DETECTING INSUFFICIENTLY COMPRESSED LAMINATED CORES OF A ROTOR BY MEANS OF A STRUCTURE-BORNE-SOUND RESONANCE DETECTION USING AN ELECTRODYNAMIC STRUCTURE-BORNE-SOUND EXCITATION
The invention relates to a method for detecting the connection state of laminated cores (P), which are compressed together, of a rotor (R) of an electric machine (EM). According to the invention, structure-borne sound is introduced into the shaft (W) or into the rotor (R) by generating a magnetic field which acts on the rotor (R). The sound, which propagates within the rotor (R), is detected while the structure-borne sound is being introduced and/or within a period of time which immediately follows the introduction of the structure-borne sound. It is ascertained whether the detected sound exhibits a resonance behavior (RV) within a frequency band (FB) which characterizes the vibration of an individual laminated core (P). A signal which represents laminated cores (P) that are insufficiently compressed together is output if a resonance behavior has been ascertained in the frequency band (FB), otherwise a signal is output which represents laminated cores (P) that are sufficiently compressed together.

The invention relates to a vibration damper (16) with a fixing means (18) which fixes a damper mass (10) if a first limit frequency is reached or undershot and if a second limit frequency is reached or overshot. Here, the damper mass (10) is preferably fixed solely by the rotational-frequency-dependent centrifugal force which displaces, for example, one control mass (20) per damper mass (10) in the radial direction R counter to the force of a control spring (22). Resonances which lie outside the limit frequencies can be avoided by the vibration damper (16) being switched on and off. When used in the drive train of a motor vehicle, with the vibration damper (16) preferably being connected in the drive train here to a crankshaft of an internal combustion engine, the vibration behaviour of the crankshaft can be influenced in such a way that the amplitude of the vibrations of the crankshaft lies below a predefinable limit amplitude.

The hydraulic system (1) presented here advantageously makes it possible for the sump to be designed merely in the form of a dry sump (5) which does not contain a separate pump module with a dedicated drive motor for delivering the hydraulic medium. Rather, hydraulic medium is delivered from the dry sump (5) via the dry sump pump flow (7) into a high sump (3), which is located above the dry sump (5). It is thus possible for the dry sump (5) to be made much smaller than a conventional gearbox sump or an oil pan. At the same time, it is possible to avoid the situation where the presence of a pump module in the gearbox sump means that, rather than the level of hydraulic medium being able to be kept beneath all the rotating components, components rotate in the hydraulic medium. In comparison with known systems, the design of the hydraulic system (1) proposed here therefore avoids churning losses. At the same time, having a common drive shaft (11) enables the drive of the pump flows (7, 9) to allow the corresponding pump module (6) to be easily controlled and to be of a simple construction.

The first fastener extends through the center housing and into the shaft portion to secure the center housing to the lower housing.
A motorized system includes a motor that drives rotation of an input shaft, a first gear system coupled with the input shaft, a spindle drive, and a measuring arrangement. The spindle drive has a driving element that is coupled with the first gear system, such that rotation of the input shaft prompts rotation of the driving element via the first gear system, and a driven element that is engaged with the driving element, such that rotation of the driving element drives axial movement of the driven element. The measuring arrangement includes a second gear system coupled with the input shaft, an indicator coupled with the second gear system, such that rotation of the input shaft prompts rotation of the indicator via the second gear system, and at least one limit switch with which the indicator interacts to control operation of the motor.
A dirt-proof electric connection between a first installation area and a second installation area of a component is provided. The connection is characterized in that a printed circuit board is provided with a plastic encapsulation. The plastic encapsulation is designed to rest internally against a wall of the housing of a component in a first transversal direction and in a second transversal direction.
