DIFFERENTIAL

摘要

An improved locking differential for driving a pair of vehicle axles. The differential includes a rotatable case. A differential pinion is supported by the case and meshes with side gears to drive the axles. A clutch assembly is carried by the case and connects the side gear with the case upon actuation. Fluid power actuates the clutch assembly to connect the case and side gear. The improvement comprises the fluid power means having a seal retainer which encircles a portion of the case. The seal retainer has a system for evenly distributes forces applied to the axially extending portion of the case during delivery of pressurized fluid to the clutch assembly to minimize relativemovement between the seal retainer and the case. The system comprises oppositely facing surfaces formed in the seal retainer being substantially equalin area to offset oppositely directed forces acting within the seal retainer when pressurized fluid is communicated to the clutch assembly.
