Patent number: 12163558Abstract: A constant velocity joint for a vehicle. The constant velocity joint includes: an axle housing fixed to a knuckle by a hub bearing, and a joint assembly inserted into the axle housing to transmit power from a shaft to the axle housing through a plurality of joint balls. In particular, the axle housing includes an extension portion which is extended from an end portion of the axle housing in a radial direction of the axle housing, and the extension portion provides a pressing force to an inner race of the hub bearing in an axial direction of the axle housing. The constant velocity joint further includes a boot surrounding an outer side of the extension portion and coupled to the extension portion so as to form a restraining force between the extension portion and the boot in the axial direction.Type: GrantFiled: August 28, 2023Date of Patent: December 10, 2024Assignees: HYUNDAI MOTOR COMPANY, KIA CORPORATION, HYUNDAI WIA CorporationInventors: Sung Su Yoo, Won Jun Choi, Hee Il Kim, Chang Hee Jeong, Yeong Wook Cho, Bum Jae Lee
