Abstract: A wheel bearing assembly includes an outer race in which a plurality of rows of track portions are formed at an inner side thereof; a hub that is coaxially disposed with the outer race to be rotatably disposed in the outer race; an inner race that is engaged with a portion of an outside surface of the hub to rotate together with the hub; a first roller that is interposed between the hub and the outer race to be rolled; and a second roller that is interposed between the inner race and the outer race to be rolled.

Abstract: The present invention discloses a wheel bearing assembly according to an exemplary embodiment of the present invention may include: an outer race in which a plurality of rows of track portions are formed at an inner side thereof; a hub that is coaxially disposed with the outer race to be rotatably disposed in the outer race; an inner race that is engaged with one side outside surface of the hub to rotate together with the hub; and rollers that are interposed between the hub and the outer race and between the inner race and the outer race to be rolled.

Abstract: A wheel end assembly includes a carrier and a wheel bearing assembly, and an outside inner race is integrally formed with a spindle of the wheel bearing assembly. The wheel end assembly includes: a carrier having a cylindrical member on its one side and a second through pipe on its other side; and a wheel bearing assembly comprising a spindle integrally formed with an outside inner race on its one side and having an insert groove on its other side, a hub having an outer race having ball receiving members receiving balls, an inside inner race provided on the inner side of the outer race by pressurization, and a seal member sealing a gap between the inside inner race and the outer race.

Abstract: The present invention is related to a connecting structure for a wheel bearing and a constant velocity joint which are connected and assembled by applying a plastic deformation of material using an orbital forming process or a swaging process. According to the present invention, the efficiency of assembly is improved and the length of a shaft is shortened compared with prior art to achieve a weight reduction. In the connecting structure, a coupling groove is formed on a hub of the wheel bearing, a recess is formed on a circumference of a shaft of the constant velocity joint, the shaft is inserted into the hub to be spline-connected with the hub, a circlip is inserted into the recess, the circlip is shrunk in the course of inserting the shaft into the hub, and the circlip is restored to former state by its elasticity and inserted into the coupling groove when the circlip is positioned on the groove.
