SPERR-DIFFERENTIAL

摘要

A locking differential includes a case which is rotatably driven by a power source. A cross shaft is mounted within the case for rotation therewith. A pair of pinion gears are rotatably mounted on the ends of the cross shaft. The pinion gears mesh with side gears splined onto respect axle shafts. Thus, when the case is rotated, torque is transmitted through the cross shaft, the pinion gears, and the side gears to the axle shafts. A locking collar is journalled on one of the side gears for axial movement between locked and unlocked positions. In the locked position, the locking collar is connected to the side gear for rotation therewith. In the unlocked position, the side gear is free to rotate relative to the locking collar. The locking collar is connected to a shifting collar by a plurality of spoke portions which extend through respective slots formed through the case. Bearing means are provided in each of the slots for engaging and guiding the axial movement of the shifting and locking collars.
