Abstract
A compact wheel end (A) serves to couple a road wheel (B) to a suspension system component (C) on an automotive vehicle and to transmit torque from a CV joint (D) to the road wheel. The wheel end includes a housing (2) that is attached to the suspension system component and a hub (4) provided with a drive flange (18) on which the road wheel is mounted and a spindle (20) that extends through the housing. The hub rotates relative to the housing on a double row tapered roller bearing (6), the raceways (40, 42, 44, 46) of which are surfaces on the housing and hub spindle. The wheel end also has a coupler (8) that is engaged with the hub spindle and the CV joint through mating splines (32, 72, 76, 94) and further provides a rib face (52) that backs the rollers (62) of the inboard row. The CV joint has a small diameter stub shaft (92) that extends through the hub to secure the CV joint to the hub, but does not transmit torque. The tapered roller bearing and coupler enable the wheel end to assume a radial size smaller than conventional wheel ends.
