A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing is operationally coupled to the shift actuator and a linear clutch actuator. The linear clutch actuator is a self-adjusting actuator, and the transmission includes a self-adjusting clutch.

A clutch apparatus for a vehicle drive train for transmitting torque between the vehicle's engine and gearbox. Three interoperative clutch members are provided. The clutch members cooperate with clutch plates, a pressure-receiving plate, a clutch pressure plate, clutch pressure springs, and a setting device between the second and the third clutch members, for setting a back torque between the third and first clutch members by an axial displacement of the third clutch member relative to the second clutch member. The setting device has two ring elements, which are rotatable n relation to each other, with ramp segments, and having balls arranged between the ramp segments; the ramp segments have regions with ball that rise or slope in opposite directions in such a way that when the ring elements rotate in the same direction, the distance between the ramp segments is smaller than when the ring elements rotate in opposite directions.

A twin plate separation system, comprising a pressure plate, an intermediate plate facing the pressure plate, and a spring separator assembly. The spring separator assembly comprises a mounting extending out from the intermediate plate towards the pressure plate. A spring surrounds the mounting, and the spring is biased to push the pressure plate and the intermediate plate apart. The mounting or another fixture can secure at least one drive strap to the intermediate plate. Alternatively, the mounting extends out of the pressure plate towards the intermediate plate, and the spring surrounds the mounting and is biased to push the pressure plate and the intermediate plate apart. In this alternative, the intermediate plate does not comprise a hole for receiving the mounting.
