In a power transmission apparatus, a second clutch includes a divider dividing driving clutch plates and driven clutch plates in an axial direction such that a first region adjacent to a clutch pressure plate and a second region adjacent to a centrifugal clutch are defined. The second clutch presses the driving clutch plates and the driven clutch plates in the first region and the second region against each other during operation of the centrifugal clutch, and presses the driving clutch plates and the driven clutch plates in the first region against each other during operation of a back torque transmission cam.

A locking mechanism comprising a linkage assembly comprising a first link and a second link joined at a pivot point; a linkage assembly spring to bias the linkage assembly into a first, locked, position; a cam assembly having a cam 1 with a cam surface in engagement with the linkage assembly; a cam biasing member such as a spring arranged to bias the cam surface to press against the linkage assembly sufficiently to overcome the linkage assembly spring and to force the linkage assembly into a second, unlocked position; and a solenoid assembly arranged to engage the cam in a locked position in which the cam is prevented from forcing the linkage assembly into the unlocked position.

A shift arrangement for a motor vehicle transmission has a housing. At least two push rods are mounted on the housing so as to be movable in an axial direction between a neutral position and a shift position. The push rods can each be coupled to a shift clutch. At least two return rods are mounted on the housing. The return rods are each coupled to one of the push rods so that a push rod and the return rod associated therewith are moved in opposite axial directions. A shift cam of a shift member can be aligned with a push rod or with a return rod for the purpose of selecting, and can transmit a pushing force to a selected rod. A driving feature is arranged on the shift member and can transmit a pushing force in order to move an unselected rod into the neutral position.
