Abstract:
A wheel end assembly with hub lock for a driving axle of a motor vehicle, said wheel end assembly with hub lock comprising:a knuckle including a bore formed therethrough;a constant velocity (CV) joint having an inner member or race capable of being drivingly coupled for rotation with an axle shaft to receive torque therefrom and an outer member or race drivingly coupled to said inner member or race, said outer member or race of said constant velocity (CV) joint including a reduced diameter portion and a plurality of splines on an outside diameter thereof;a hub flange mounting member including an inwardly extending substantially cylindrical hub trunnion portion having a hollow portion and a plurality of splines on an outside diameter thereof, said reduced diameter portion of said outer member or race being supported for rotation by at least one bearing assembly within said hollow portion of said inwardly extending substantially cylindrical hub trunnion portion of said hub flange mounting member which, in turn, is supported for rotation within said bore of said knuckle by at least one bearing assembly;an adaptor flange having a plurality of splines corresponding to said plurality of splines on said outside diameter of said inwardly extending substantially cylindrical hub trunnion portion of said hub flange mounting member on an inside diameter thereof, said adaptor flange also including a plurality of splines on an outside diameter thereof; anda locking collar having a plurality of splines corresponding to said plurality of splines on said outside diameter of said outer member or race of said constant velocity (CV) joint and to said plurality of splines on said outside diameter of said adaptor flange on an inside diameter thereof, said locking collar being laterally movable to selectively engage, or not engage, with said plurality of splines on said outside diameter of said adaptor flange and transmit, or not transmit, torque from said constant velocity (CV) joint to said hub flange mounting member.
