Methods, systems, and vehicles that control the temperature of a device included in the vehicle are presented herein. The temperature of the device is controlled by ventilating the device with drivetrain air, such as transmission cooling air. In some embodiments, the device is at a greater temperature than the drivetrain air, which cools the device. In other embodiments, the device is at a lesser temperature than the drivetrain air, which heats the device. The drivetrain air is provided to the device through an exhaust duct coupled to the vehicle's transmission. The drivetrain exhaust air is preferably circulated by the transmission. The transmission may be a continuously variable transmission. The device may be an oxygen sensor that is coupled to an engine exhaust pipe. The oxygen sensor is thermally coupled to the engine exhaust and the engine exhaust pipe, which are at greater temperatures than the transmission exhaust air.
A skid frame for a snowmobile is disclosed including a generally planar skid surface extending between front and rear idler wheels. The front and rear idler wheel are offset from one another and define a longitudinal direction. A track encircles the skid frame having the skid surface positioned over a center of the track such that a major longitudinally extending portion of the track that is coextensive with the skid surface has first and second unsupported lateral portions on either side of the skid surface. The first and second unsupported lateral portions extend in the horizontal direction at least 25 percent of a width of the track. A suspension arm member may mount the skid rail and include mount portions for mounting to a tunnel and spanning a distance at least twice the width of the longitudinal beam.
A door (114) for a recreational vehicle (110) having a chassis with a step-through door opening. The door includes a forward end and a rearward end, and a hinge (138) coupled between the rearward end of the door and the chassis of the vehicle. The door includes a latch (146) at the forward end of the door to provide one operational step to release or secure the door to the chassis upon ingress or egress of the vehicle.
An electronic control unit ("ECU", (14)) for limiting at least one vehicle parameter, a corresponding method and a storage medium for storing corresponding instructions is disclosed. The electronic control unit (14) may be configured to receive a user-specified vehicle parameter limit, such as a speed limit, from an input device (30), such as a gauge interface of the vehicle or a diagnostic tool. The electronic control unit (14) is further configured to enforce the received vehicle limit, without a need to reprogram (e.g., erase and rewrite) vehicle engine control data stored by the electronic control unit (14), such as lookup tables or maps that are used to determine the operational parameters (e.g., ignition timing, throttle) based on sensor inputs (e.g., engine revolutions per minute, engine temperature).
B60K 31/04 - Vehicle fittings, acting on a single sub-unit only, for automatically controlling vehicle speed, i.e. preventing speed from exceeding an arbitrarily established velocity or maintaining speed at a particular velocity, as selected by the vehicle operator including electrically actuated servomechanism and means for comparing one electrical quantity, e.g. voltage, pulse, waveform, flux, or the like, with another quantity of a like kind, which comparison means is involved in the development of an electrical signal which is fed into the controlling means

A recreational off-highway vehicle includes side-by-side passenger and driver seats held within a chassis that is approximately 50 inches wide. The seats sit low in the chassis and are covered by a roll cage. Grab handles are positioned on the sides of the passenger seat. Select large round tubing protects the vehicle, while rectangular tubing frames the portions of the vehicle beneath body panels. The vehicle is powered by an engine rearward of the seats that is connected to a transaxle. The engine and transaxle are isolation mounted together with a portion of the air intake assembly. The vehicle is suited for rough terrain travel.
A retainer plate for preventing or at least mitigating loosening of an axle nut of a vehicle. The retainer plate comprises a generally flat section of rigid material that couples to an axle nut in a non-rotatable fashion and to a portion of the wheel to maintain the axle nut in tight threaded engagement with the axle. The retainer plate can have a central bore that non-rotatably engages the axle nut and a radially outward feature that engages the wheel to prevent the axle nut from loosening.
F16B 41/00 - Measures against loss of bolts, nuts, or pinsMeasures against unauthorised operation of bolts, nuts, or pins
F16B 39/10 - Locking of screws, bolts, or nuts in which the locking takes place after screwing down by a plate or ring immovable with regard to the bolt or object
