COMPACT UNITIZED HUB ASSEMBLY

摘要

A hub assembly A for coupling the road wheel of a vehicle to the suspension system of the vehicle includes a hub (2) provided with a spindle (12), a housing (4) surrounding the spindle (12) of the hub (2), and an antifriction bearing (6) located between the spindle (12) and the housing (4). The bearing (6) includes tapered rollers (50) arranged in two rows as well as a pair tapered inner raceways (34) carried by the spindle (12) and a pair of tapered outer raceways (54) carried by the housing (4). One of the tapered inner raceways (34) is on a race (30) that is initially separate from the housing (4), and this race (30) has a recess (44) that opens axially out of its end. The spindle (12) has an integrally formed end that is received in the recess (44). The spindle (12) and inner race (30) may be engaged with splines (106), (108) and the inner race (30) may further have an axial extension (110) provided with an external spline (112) that is selectively engaged by a connect-disconnect ring (116) on a CV joint K.
