Problems solved by technology

However, contamination of the wheel assembly, especially from salt and / or chlorides used to melt snow and ice, can lead to corrosion of the mating interface between the joint and the outer ring
If the corrosion is severe enough, the outer race may seize in the fitting, preventing removal of the outer race from the fitting

Embodiment Construction

[0049] Referring to the drawings, wherein like numerals designate corresponding parts throughout the several views, a wheel assembly is shown generally at 20 . The wheel assembly 20 is used in a vehicle and rotatably supports wheels (not shown) relative to the vehicle.

[0050] The wheel assembly 20 includes a joint 22 . The connector 22 is configured to connect to the vehicle. The connector 22 may be configured in any suitable manner for connection to the vehicle, and may be configured as desired to meet any particular design parameters. The joint 22 defines an annular bore 24 extending along the longitudinal axis 26 . The annular hole 24 extends through the joint 22 between the outer surface 28 of the joint 22 and the inner surface 30 of the joint 22 . The annular hole 24 includes a chamfered end 32 placed adjacent the outer surface 28 of the fitting 22 . As described below, the chamfered end 32 facilitates the insertion of the outer ring 34 into the annular bore 24 .

Abstract

A bearing cap for a wheel assembly includes a bearing cap seal for sealing against an annular bore of a knuckle. The bearing cap is coupled to an outer ring, which is disposed within an annular bore of a knuckle. The bearing cap includes a face and a collar extending along a longitudinal axis into the annular bore. The bearing cap seal is disposed annularly about the collar, within the annular bore. The bearing cap seal prevents contamination of an engagement interface between the knuckle and the outer ring.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of US Provisional Patent Application Serial No. 61 / 297942, filed January 25, 2010, and is incorporated herein by reference. technical field [0003] The present invention relates generally to wheel assemblies for vehicles and, more particularly, to seals for bearing caps of such wheel assemblies. Background technique [0004] A typical wheel assembly includes a knuckle that is configured to connect the wheel assembly to the vehicle. The joint defines an annular bore extending along the longitudinal axis. The wheel assembly also includes an outer race disposed at least partially within the bore. The outer race includes a portion having an outer diameter substantially equal to the inner diameter of the annular bore of the fitting, and engages the annular bore in an engagement interface therebetween to position the outer race relative to the fitting. The wheel assembly also includes a...
