摘要： A vehicle transmission includes a shaft; speed-changing gears; switching mechanisms; and a shifting mechanism. The shifting mechanism is provided with a double-meshing preventing mechanism configured to switch between a one-way state in which the switching mechanisms are hindered from moving in a downshift direction and allowed to move in an upshift direction and a free state in which the switching mechanisms are allowed to move in both the downshift direction and the upshift direction.

摘要： A first dog ring and a second dog ring are biased toward each other by means of springs. When the first dog ring and the second dog ring are moved away from each other, bias force produced by the springs is applied to the second dog ring in a direction to draw the second dog ring toward the first dog ring. Accordingly, when the first dog ring is moved away from the second dog ring during shifting, the second dog ring is drawn toward the first dog ring under the bias force, and third engaging teeth of the second dog ring and meshing teeth of a first-speed gear are promptly disengaged from each other.

摘要： Auxiliary transmission actuation mechanism 200 in a power transmission unit of a vehicle includes a transmission actuating gear 202, a gear driven bush 204, a gear actuating means 206, a shift fork 208, a shift rail 210, a clutch control valve actuating arm 212, a rail shifting means 214. The transmission actuating gear 202 is used to drive at least one of an even shaft and an odd shaft which in turn drives an output shaft through gears thereby propelling the vehicle when at least one of a dual clutch unit and a hydraulic system of vehicle is not functioning. The clutch control valve actuating arm 212 is adapted to engage a movable member of a clutch control valve assembly 100V thereby actuating clutch control valve 100V to de-actuate the dual clutch unit.

摘要： A speed select shift mechanism for a belt drive assembly to be installed on a shaft capable of shifting between high, low and neutral speeds is disclosed. The shift mechanism includes a shift collar that is enclosed within an enclosure to prevent debris from contacting the inner operations of the shift mechanism and thereby reduce wear and tear of the shift mechanism along with down time for maintenance of the device. The shift mechanism includes a shaft, a first pulley, a shift collar, a second pulley and a shifter. The shift collar further includes dowels that cooperatively engage corresponding apertures on the pulleys.

摘要： An exemplary shift lever includes a mounting assembly, a flexible member coupled to the mounting assembly, and an interface coupled to the flexible member. The flexible member is resilient so as to provide a selected biasing force at a predetermined deformation angle, and flexible enough to elastically deform across a selected angular range. The mounting assembly is configured for connection with the input shaft of a transmission, and the interface is configured for connection with an output of a drive selector.
