A gearbox includes an input gear supported for rotation about an input axis and includes first and second idler gears fixedly coupled to each other and supported for rotation about a transfer axis. The first idler gear is fixedly coupled to the input gear. A planetary gear set is supported for rotation about an output axis of the gearbox and has a first component fixedly coupled to the second idler gear. A differential is supported for rotation about the output axis, co-axial with the planetary gear set, and fixedly coupled to a second component of the planetary gear set.

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 shifting device for a positively engaging clutch having complementary first and second positively engaging coupling elements includes a housing and an actuator rod which is axially movable within the housing by means of an associated rod actuating mechanism. A clutch shift fork for engagement with the first coupling element is mounted on the actuator rod for axial movement of the first coupling element into and out of engagement with the second coupling element in response to axial movement of the actuator rod. The clutch shift fork is mounted on the actuator rod by a threaded connector such that the clutch shift fork is axially movable on the actuator rod. Thus conveniently the axial position of the clutch fork on the shaft may be altered by rotating the shaft relative to the clutch fork for accurate positioning of the clutch fork relative to the coupling element with which it engages.

An electric vehicle transmission method includes the steps of: detecting a gear-shift command; judging if the gear-shift command is in conflict, if it is in conflict, then it returns back to the step of detecting the gear-shift command while if it is not in conflict, then proceeds to the next step; proceeding to a synchronized position, a dispelling fork drives a synchronizer to make the synchronizer move from the original gear position to a synchronized position, and the dispelling fork does not move within a synchronized time; and proceeding to a target position, the dispelling fork drives the synchronizer again to make the synchronizer move to the target gear position.

The present invention provides a self-aligning clutch release bearing in which consideration is taken for a fiber flow in a steel sheet of which a side plate is made. Specifically, the side plate is formed with cutout portions at locations where an imaginary line passing through the cutout portions and the center of an inner-diameter portion is across the fiber flow in the steel sheet of which the side plate is made. With this arrangement, the present invention makes it possible that cracks do not develop easily from the cutout portions when a flange portion is formed by means of burring process after the side plate is punched by means of blanking process. This leads to improved yield and increased strength of the side plate.

A clutch assembly incorporated into a power transfer assembly (72) of a motor vehicle is presented. The clutch assembly includes a power-operated clutch actuator (306) for moving a clutch sleeve (354) axially between released and engaged positions between two rotatory members. In the released position, relative rotation between two rotary members is prevented. Whereas in the engaged position, relative rotation is permitted. The power-operated clutch actuator (306) further includes an electromagnetic solenoid with an output member having an extended condition and a retracted condition urging the clutch sleeve (354) between positions. A shift isolation linkage mechanism (304) interconnects the output member of the solenoid to the clutch sleeve (354) and permits movement of the output member to its retracted position while a blocked tooth condition inhibits movement of the clutch sleeve (354) to its engaged position. Once the blocked tooth condition is removed, the isolation linkage mechanism (304) forces the clutch sleeve (354) to its engaged position.
