Abstract
A vehicle wheel hub with a flange by which a wheel is mounted, the hub being supported by a knuckle and rotated through a universal joint, such as a CV joint, the CV joint having an outer joint member or shell with a cylindrical end having an end face. Axially spaced inboard and outboard tapered roller bearing members are positioned between the hub and the knuckle. The inboard bearing member has a cone with a raceway and a back face but no thrust rib. The shell cylindrical end face abuts the inboard cone back face and is adapted to engage the back faces of tapered rollers of the inboard roller bearing member to serve as a thrust rib for the inboard bearing member.
Claims6
In an automotive vehicle having a wheel hub with a flange by which a wheel is mounted, said hub being supported by a support member and rotated through a CV joint, the CV joint having a shell with a cylindrical end having an end face, and axially spaced inboard and outboard bearing members between said hub and said support member, said inboard bearing member being a tapered roller bearing with a cone having a raceway and a back face but no thrust rib as a part of said cone, the improvement comprising said shell cylindrical end face abutting said cone back face and adapted to serve as a thrust rib of said bearing member.
In combination with an automotive vehicle, a hub assembly for coupling a road wheel to a suspension system of said automotive vehicle, said hub assembly comprising a hub with a flange by which said wheel is mounted, said hub being supported by a support member and rotated through a CV joint, the CV joint having a shell with a cylindrical end having an end face, and axially spaced inboard and outboard bearing members between said hub and said support member said inboard bearing member being a tapered roller bearing with a cone having a raceway and a back face, the improvement comprising said inboard cone having no thrust rib and said shell cylindrical end face abutting said cone back face and adapted to serve as a thrust rib of said inboard bearing member.
In an automotive vehicle having a wheel hub with a flange by which a wheel is mounted, said hub being supported by a support member and rotated through a universal joint, the universal joint having an element with an end face, and axially spaced inboard and outboard bearing members between said hub and said support member, said inboard bearing member being a tapered roller bearing with a cone having a raceway and a back face but no thrust rib as a part of said cone, the improvement comprising said universal joint element end face being shaped complementarily to and having a portion abutting said cone back face and a lip portion adapted to serve as a thrust rib of said bearing member.
