LUBRICATING STRUCTURE FOR POWER TRANSMISSION DEVICE
A lubricating structure for a power transmission device wherein a rotary element chain (9) having a plurality of intermeshed gears is housed within a case (17, 18), and a first gear (10) positioned at the lowermost part of the rotary element chain supplies lubricating oil (OL) to inside of the case by scraping up lubricating oil which collects on a bottom part of the case. The bottom part of the case is a two-layer bottom part (25) comprising an inside bottom wall (22) where the lubricating oil collects, and an outside bottom wall (24) formed so as to provide a space (23) to the outside of the inside bottom wall. Moreover, the inside bottom wall is adjacent to the first gear and a second gear, and is formed so as to slope downward towards the first gear positioned at the lowermost part.
This transmission mechanism comprises a power selection mechanism (25) and a controller (27). The power selection mechanism switches between a state in which transmission of rotational power of the drive source from the input shaft to the output unit is enabled by moving a sleeve (31) in the engaging direction of the input unit (M1) and the output unit (10); and a released state in which the engagement of the input-side dog tooth and the output-side dog tooth is released by moving the sleeve in the release direction of the input unit and the output unit, thereby disabling the transmission of rotational power from the input unit to the output unit.

This transmission mechanism is provided with: a first gear (18) fixed coaxially to a hollow rotation shaft (17); a second gear (20) and a third gear (21) which are opposite of each other on the outer periphery of the rotation shaft and are arranged coaxially and capable of rotation; a gear selection clutch (50) which is arranged between the second gear and the third gear, and which selects either a state in which the second gear and the first gear are coupled and the third gear and the first gear are uncoupled, or a state in which the third gear and the first gear are coupled and the second gear and the first gear are uncoupled; and a clutch operation unit (51) which links an operation shaft (40) arranged in the hollow portion of the rotation shaft to the gear selection clutch and which operates the gear selection clutch by axially advancing and retracting the operation shaft.

According to the present invention, during starts, rotational force is transmitted by a first clutch (50) from a turbine (30) to an input shaft (2), and transmission of rotational force by a second clutch (60) from a rotational body (11) to the input shaft (2) is cut off. During lock-up, transmission of rotational force by the first clutch (50) from the turbine (30) to the input shaft (2) is cut off, and rotational force is transmitted by the second clutch (60) from the rotational body (11) to the input shaft (2). The present invention can suppress transmission loss during lock-up because the first clutch (50) and the second clutch (60) transmit rotational force as a result of the engagement of a plurality of rollers (53, 63). The present invention can suppress shock during lock-up and improve transmission efficiency during lock-up because the rollers (53, 63) absorb shock during engine torque fluctuations or the like.
According to the present invention, when torque is transmitted from an engine (3) side to a transmission (5) side, as a result of the relative rotation of an inner ring (12) with respect to a first outer ring (15), a first roller (17) rotates between an input raceway surface (13) and an output raceway surface (16) and revolves around a center axis O. The inner ring (12) and the first outer ring (15) move relative to each other in the axial direction, and the first roller (17) engages the inner ring (12) and the first outer ring (15). The present invention can absorb large torque fluctuations because the rotation/revolution of the first roller (17), the elastic deformation of the input raceway surface (13) and the output raceway surface (16), etc. ensure damping from a low torque region to a high torque region.

A power transmission apparatus (10) to be disposed in a power transmission pathway for transmitting torque and rotation speed. Shock during torque transmission can be absorbed because an inner ring (12) and a first outer ring (15) engage with first rollers (17) and move relative to each other in the axial direction during torque transmission. A limiting device (30) limits the movement of the first outer ring (15) in the axial direction when the inner ring (12) and the first outer ring (15) engage with the first rollers (17). As a result, the rolling of the first rollers (17) is restricted, inhibiting torque increase and making it possible to cut torque appropriately without a sense of anything being strange.

Provided is a transmission which eliminates torque loss during gear shift and with which the processing of components can be simplified. When an axial force is generated in a protrusion (105) due to a guide portion (82) that is inclined relative to the axial direction, a clutch ring (90) separates from a transmission gear in the axial direction by the same amount as the axial length of the guide portion (82). An axial force is generated in the protrusion (105) by means of a first portion (77) during gear shift from a low gear to a high gear, and when a low-speed transmission gear and the clutch ring (90) separate from each other, a high-speed transmission gear and the clutch ring (90) interlock. Since the guide portion (82) can be formed in a second wall (75) when providing a groove portion (73), an increase in the processing workload required to provide the guide portion (82) can be suppressed, and there is no need for processing to provide a slope in the clutch ring (90).

Provided is a transmission which eliminates torque loss during gear shift and with which the processing of components can be simplified. An axial force is generated in a protrusion (105) by means of a first portion (77) during gear shift from a low gear to a high gear, and when a low-speed transmission gear and a clutch ring (90) separate from each other, a high-speed transmission gear and the clutch ring (90) interlock. Since relative movement of the protrusion (105) in a neutral direction is suppressed by means of a first retaining portion (134) during coasting, gear disengagement whereby the transmission gears and the clutch ring (90) separate from each other can be suppressed. Since the first retaining portion (134) can be formed in a first wall (132) when providing a groove portion (131), an increase in the component processing workload can be suppressed.

Provided is a stepless transmission (10) having a simplified hydraulic circuit. Drive force in a forward and backward movement direction relative to a variator (11) is applied to a carriage (17) by a hydraulic cylinder (20) having first and second oil chambers (23, 24). A first oil passage (31) and a second oil passage (32) are connected to the first and second oil chambers (23, 24), respectively, and a first hydraulic pump (33) is connected to the first oil passage (31) and the second oil passage (32). A pump drive device (34) drives the hydraulic pump (33) in a first direction and a second direction which is opposite the first direction; therefore the single hydraulic pump (33) can supply hydraulic oil to the first and second oil chambers (23, 24) through the first oil passage (31) and the second oil passage (32). As a result, the hydraulic circuit can be simplified.

Provided is a torque converter (10) such that shock during lockup can be suppressed. A transmission device input shaft (4) is coupled to a first element (53) of a planetary gear device (50), a turbine (30) is coupled to a second element (51), and a rotary body (11) is coupled to a third element (54) in a disconnectable manner. A clutch device (60) transfers or interrupts the transmission of turning force between two elements of the planetary gear device (50) and between the rotary body (11) and the third element (54). Torque amplification or lockup can be performed with the clutch device (60). Because the rotary body (11) and the input shaft (4) are coupled via the planetary gear device (50) during lockup, torque fluctuation and the like can be absorbed by the planetary gear device (50) and shock can be suppressed.
F16H 47/08 - Combinaisons d'une transmission mécanique avec des embrayages à fluide ou une transmission à fluide la transmission à fluide étant du type hydrocinétique la transmission mécanique étant du type à organes à mouvement orbital
Provided is a torque converter with a structure that can be simplified. When the turning force of a motor is input to a pump (20), the turning force is transmitted to a turbine (30) via a fluid. When a rotary body (11) and the turbine (30) are disconnected from each other by a clutch device (50), the turning force of the motor (2) is amplified. Meanwhile, when the turning force is transmitted between the rotary body (11) and the turbine (30) via the clutch device (50), the torque converter can be locked up so that the turning force is output to the turbine (30) without having to be transmitted via the fluid. Since the pump (20) and the turbine (30) are built into a case (12) and the fluid is enclosed in the case (12), the structure can be simplified compared to conventional torque converters that are integrated with a transmission device.

Provided is a vehicle dual-clutch transmission in which a clutch mechanism and a transmission mechanism are integrated into a single structure, thereby allowing a reduction in overall length. The vehicle dual-clutch transmission is provided with: a main shaft (11) to which power from an engine (7) is input; a first input shaft (31) and a second input shaft (32) that are arranged coaxially with the main shaft (11); a first friction clutch (21) that can transmit the power from the main shaft (11) to the first input shaft (31); a second friction clutch (22) that can transmit the power from the main shaft (11) to the second input shaft (32); a gear shift mechanism (40) that can select any one of a plurality of shift positions by connecting/disconnecting the power from the first input shaft (31) and the second input shaft (32) and shift gears; and an output shaft (12) that outputs the power from the gear shift mechanism (40).

Provided is a clutch device capable of reliably transmitting predetermined torque. Power is transmitted from an outer ring to a second gear through a first gear. The teeth of the first gear are formed so that the lines of the teeth are non-parallel to the center axis. The direction of axial force generated by the reaction force of the second gear and acting on the first gear is set to be the same as the direction of movement of the outer ring. When rollers engage with raceway surfaces and power is transmitted from the first gear to the second gear, the reaction force of the second gear promotes the movement of the outer ring in the axial direction. Predetermined torque can be reliably transmitted because axial pull-in force between an inner ring and the outer ring increases.

A first strut (31) is restricted from swinging toward an engaging concavity (15) by a restricting member (60) until one end of a second strut (32) engages in the engaging concavity (15). As a result, the first strut (31) can be prevented from starting to swing when a notch plate (10) is rotating in a first direction relative to a pocket plate (20). Consequently, it is possible to prevent shocks caused by changes in inertia that occur together with the engaging of the first strut (31). Furthermore, one end of the first strut (31) can be prevented from hitting the engaging concavity (15) before the one end of the first strut (31) is sufficiently inserted into the engaging concavity (15). Consequently, it is possible to prevent the one end of the first strut (31) and the wall surface of the engaging concavity (15) from being damaged by concentrated loads.

The ratio between the numbers of rotations of the first intermediate shaft (6) and the second intermediate shaft (7) is increased or decreased by the linkage mechanism (40), and the respective change gears can be brought into a synchronized state with respect to the first intermediate shaft (6) or the second intermediate shaft (7). By the linkage mechanism (40), rapid gear change becomes possible, and the device configuration can be simplified and reduced in size and weight.

Provided is a transmission device that enables the transmission torque capacity of the respective clutches of two systems to be small and can reduce overall length. When a second input shaft (108) and a first transmission gear (111) are coupled by a first switching clutch (131), motive force from a drive shaft (2) is transmitted to a transmission gear train (110). It is possible to transmit torque to an output shaft (3) by simultaneously coupling a first clutch (107) and a second clutch (109), and so the respective transmission torque capacities of the first clutch (107) and second clutch (109) (clutches of two systems) can be made small. Also, the first clutch (107) and second clutch (109) are disposed in parallel, and so it is possible to reduce the length (overall length) in the axial direction of the transmission device (101) compared to the case that the first clutch and second clutch are disposed in series.

Provided is a speed reduction mechanism that can be made lightweight and compact. A speed reduction mechanism (20) comprises: a first gear mechanism (21a) comprising a first sun gear (22), and a first pinion gear (24) meshing with the first sun gear (22); a second gear mechanism (21b) comprising a second sun gear (23), and a second pinion gear (25) meshing with the second sun gear (23); and a planetary carrier (26) that rotatably supports both the first and second pinion gears (24, 25) and can input and output rotary power to the first sun gear (22) and the second sun gear (23). The speed reduction ratio is apportioned by way of the first gear mechanism (21a) and the second gear mechanism (21b).
Provided is a clutch device capable of reliably transmitting predetermined torque. Power is transmitted from an outer ring (10) to a second gear (13) through a first gear (12). The teeth (12a) of the first gear (12) are formed so that the lines of the teeth (12a) are non-parallel to the center axis (o). The direction of axial force generated by the reaction force of the second gear (13) and acting on the first gear (12) is set to be the same as the direction of movement of the outer ring (10). When rollers (8) engage with raceway surfaces (4a, 10a) and power is transmitted from the first gear (12) to the second gear (13), the reaction force of the second gear (13) promotes the movement of the outer ring (10) in the axial direction. Predetermined torque can be reliably transmitted because axial pull-in force between an inner ring (4) and the outer ring (10) increases.

Provided is a solar tracking device with which the output can easily be detected. Light-receiving parts (9) which receive sunlight are supported by a first shaft (7) constructed so as to be capable of rotating in response to the bearing of the sun and a second shaft (8) constructed so as to be capable of rotating in response to the elevation of the sun. The first shaft (7) is arranged with the center of the rotational axis (O) inclined with respect to the gravity axis (G), so when the first shaft (7) rotates, a first tilt sensor (41) affixed to the first shaft (7) rotates around the center of the rotational axis (O) while the angle of the gravity axis (G) and the detection axis (D) changes - in other words, while the sensor output changes. The output can easily be detected by correlating the rotational angle of the first shaft (7) and the sensor output of the first tilt sensor (41). When the first tilt sensor (41) is affixed to the second shaft (8), which rotates in conjunction with the first shaft (7), or to the light-receiving parts (9), the output can easily be detected in the same manner.

Provided is a sun tracking device wherein the number of reduction devices and motors can be reduced, size reduction and weight reduction are possible, and production costs can be reduced. The rotation of a motor (4) in one direction is transferred to a drive shaft (6) from a reduction device (5), and the rotation is transferred in a first transfer part (10) and a second transfer part (20). The rotation is transferred to a first shaft (7) by a first one-way clutch (11) for the first transfer part (10); therefore, the first shaft (7) is at least rotated according to the azimuth or the altitude of the sun. On the other hand, if the rotation of the motor (4) in the other direction is transferred to the drive axis (6), the transfer of the rotation to the first shaft (7) is interrupted by the first one-way clutch (11), and a second transfer part (20) transfers the rotation to a second shaft (8). Thus, without rotating the first shaft (7), the second shaft (8) can be rotated. As a result, the inclination of a light receiving part (9) can be changed freely.
Provided is a fluid force power generation device in which shaft power loss caused by the fact that one propeller works as a brake on the other propeller can be prevented and thereby the power generation efficiency can be improved. A first propeller (5) and a second propeller (6) having different rotational directions from each other are disposed on both ends of a main body (4) and are coupled to a first rotational shaft (7) and a second rotational shaft (8), respectively. The power of the first rotational shaft (7) is transmitted to a first element (41) (differential (40)) by a first one-way clutch (20), and the power of the second rotational shaft (8) is transmitted to a second element (42) (differential (40)) by a second one-way clutch (30). When the number of rotations of the first propeller (5) decreases and the number of rotations of the first rotational shaft (7) becomes relatively smaller than that of the first element (41), the power transmission from the first element (41) to the first rotational shaft (7) is blocked by the first one-way clutch (20). The first propeller (5) is prevented from working as a brake on the second propeller (6) having the larger number of rotations, the shaft power loss can be prevented, and thereby the power generation efficiency can be improved.

A clutch device which can, if necessary, switch between the transmission of rotation in a specific direction and the interruption of the transmission of the rotation. A load is applied to an inner retainer (5) or an outer retainer (6) by a load application device (20), and the inner retainer (5) and the outer retainer (6) are moved relative to each other about the axis (O). As a result, sprags (4) are tilted, according to the applied load, between portions of an inner ring (2) and an outer ring (3), the portions facing each other, and the inner retainer (5) or the outer retainer (6) is pressed by a pressing member (14) in the direction opposite the direction in which the inner retainer (5) and the outer retainer (6) move relative to each other. This means that driving the load application device (20) enables switching between engagement and disengagement between the sprags (4) and the inner and outer rings (2, 3). Thus, if necessary, the switching between the transmission of rotation in a specific direction and the interruption of the transmission of the rotation can be performed.

The invention provides a power transmission device in which the switching mechanism and control operation can be simplified. Regions of a first sprag (4) and a second sprag (5) on the side of an inner race (2) are retained by an inner retainer (6), and regions of the first sprag (4) and the second sprag (5) on the side of an outer race (3) are retained by an outer retainer (7). Different directions are established for the relative rotation in which the first sprag (4) engages the inner race (2) and the outer race (3), and the relative rotation in which the second sprag (5) engages the inner and outer races, whereby the inner retainer (6) and the outer retainer (7) are caused to move relative to each other about an axial center O by a load imparting device (20), and either the first sprag (4) or the second sprag (5) can be made to engage the inner race (2) and the outer race (3). The combined retention of the first sprag (4) and the second sprag (5) by the inner retainer (6) and the outer retainer (7) actuates the load imparting device (20) to allow the power transmission direction to be switched all at once, resulting in a simpler switching mechanism and control operation.

This invention is concerning a driving torque distribution method for front-and-rear-wheel-independent-drive-type electric vehicles (FRID EVs) in which it is possible to get stable steering on a low friction coefficient road surface. This method is characterized by distributing driving torque to the left and right wheels of the front and rear wheels, considering not only load movement of the longitudinal direction but also load movement of the lateral direction which is generated at cornering. The load movements are estimated by detecting components of the 3-axis directions, i.e., longitudinal and lateral accelerations and yaw rate, and the steering angle and friction coefficient of the road surface. The effectiveness of the proposed driving torque distribution method was verified using simulators equivalent to the prototype FRID EV simulated with Matlab/Simulink and CarSim software. This method is expected to be indispensable to improving running performance of FRID EVs.
