摘要： An apparatus for transferring driving force at a wheel for a vehicle may include a housing of a constant velocity joint having a center of a first end portion formed to be penetrated and inserted into a hub bearing, and a step formed on an inner peripheral surface of a middle portion of the housing, a hub flange supporting an expansion part by the step by having one end portion coupled to a wheel side and another end portion inserted into the housing to thereby form the expansion part expanded in a radial direction, and a forming member installed in the housing to face the expansion part and having an outer peripheral surface supported by an inner peripheral surface of the housing.

摘要： A wheel drive unit for a vehicle includes a connecting member separably coupled to a constant velocity joint, a hub housing accommodating the constant velocity joint, and a hub cap to seal the hub housing. In particular, a fixing groove is formed around a first end of the constant velocity joint, and the connecting member is fitted in the fixing groove in a ring shape. When the hub cap is separated from the hub housing, the connecting member can be easily disassembled from the constant velocity joint such that inner components of the wheel drive unit can be easily replaced and repaired.
