The commercial vehicle hub bearing assembly comprises a connecting mechanism, a main body mechanism and an oiling mechanism, and the main body mechanism comprises a commercial vehicle hub body, a bearing body, an oil seal, a sealing clamping ring, a middle sealing ring and a sealing ring. According to the commercial vehicle hub bearing assembly, the commercial vehicle hub body is fixedly connected to the inner wall of the flange, the oil seal is movably clamped to the inner wall of the commercial vehicle hub body, lubricating oil in the bearing body is prevented from flowing out, when a wheel rotating shaft rotates, the bearing body is driven to rotate, and a sealing clamping ring seals the inner wall of the joint of the bearing body; the middle sealing rings are clamped in grooves formed in the outer walls of the two sides of the bearing body in a sliding mode, the outer walls of the two sides of the bearing body are stabilized, sealing rings are movably clamped to the left side and the right side of the commercial vehicle hub body, sealing connection with the left side and the right side of the commercial vehicle hub body is facilitated, and the service life of the commercial vehicle hub body is prolonged. The effect of preventing lubricating oil from flowing out of the inner wall of the bearing body joint is achieved.
