CROWNED PROFILE DRIVESHAFT JOURNAL

摘要

In at least some implementations, a differential for a vehicle includes a pinion gear, a pair of side gears and a housing. The side gears are meshed with the pinion gear and the housing defines a cavity in which the pinion gear and side gears are received. The housing also has an opening with an inner end leading to the cavity and an outer end spaced from the inner end. The opening is adapted to receive a shaft therethrough for coupling of the shaft to one of the side gears and the opening is defined at least in part by a journal surface. The journal surface is concave with respect to the shaft and provides a converging portion from the inner end to a central portion between the inner end and outer end and a diverging portion from the central portion to the outer end.

1. A differential for a vehicle, comprising:
at least one pinion gear; a pair of side gears meshed with the at least one pinion gear; and a housing defining a cavity in which the at least one pinion gear and side gears are received, the housing having an opening with an inner end leading to the cavity and an outer end spaced from the inner end, and adapted to receive a shaft therethrough for coupling of the shaft to one of the side gears, the opening being defined at least in part by a journal surface that is concave with respect to the shaft and provides a converging portion from the inner end to a central portion between the inner end and outer end and a diverging portion from the central portion to the outer end.
