ABSTRACT:
The invention is concerned with novel sealing means for a differential-final drive arrangement and with an assembly method therefore. In a differential-final drive arrangement for a vehicle comprising an axle extending from a differential through a first housing and out a hole therein removed from said differential; a final drive within a second housing having gear means driven by spline means on said axle, said second housing being rotatably supported by said first housing; and a wheel integral with said second housing and rotated by said gear means, the invention provides an improved slidable seal between a first compartment defined by said differential and said first housing and a second compartment defined by said second housing. The improved slidable seal comprises a sleeve thrust bearing about the axle within the second housing having a first end in slidable sealing abutting relation with a respective one of the first housing and the gear means and a second end extending towards a respective other of the first housing and the gear means. The improved slidable seal further includes a sleeve thrust member about the axle within the second housing having a first end abutting a respective other of the first housing and the gear means and a second end fitting within the second end of the bearing. Also a part of the improved slidable seal are compression means biasing the bearing axially away from the member and resilient toroidal sealing means compressed between the axle and the bearing.
