ABSTRACT:
A differential gearing assembly including a differential case 10 that mounts axle drive gears 22 rotatably engaged with axles 20 and transfer gearing 50 for cross coupling the axle drive gears. The axle ends are secured to the differential assembly by lock rings 32 received by lock ring grooves formed on the axle ends. A thrust spacer maintains the predetermined spaced apart position of the axle ends and in one embodiment 26 comprises elements 26a 26b which when joined together by a fastener 28 capture the lock rings in their installed positions on the axle ends. The transfer gearing includes transfer gears 50 rotatably coupled to each other by intermediate gearing 54. In an alternate embodiment, a thrust spacer 70 is bisected along a line defined by stepped confronting surfaces 74a, 74b, 74c to define interfitting halves 72a, 72b. Each half is configured and sized to facilitate removal through an opening defined between the intermediate gears. The inclination angles of the teeth on the axle drive gears 22 are equal but opposed so that equal and opposed thrust forces are exerted on the differential case.
