The invention provides a wheel end assembly of a vehicle, a control method and the vehicle, and relates to the technical field of a vehicle chassis. The wheel end assembly comprises a hollow hub, a steering knuckle with a shaft, at least one thrust roller bearing and at least one cylindrical roller bearing, wherein the thrust roller bearing and the cylindrical roller bearing are arranged on the shaft in a sleeving mode and located in a gap. The shaft is located in the hub, a gap exists between the shaft and the inner wall of the hub, at least part of the outer wall of the thrust roller bearingis attached to the inner wall of the hub so as to limit radial movement of the thrust roller bearing along the shaft, the outer wall of the cylindrical roller bearing is attached to the inner wall ofthe hub, and the inner wall of the cylindrical roller bearing is attached to the outer wall of the shaft. When the cylindrical roller bearing is seriously damaged, the wheel hub of the wheel end assembly is axially supported by the thrust roller bearing, so that the situation that the wheel hub drives the wheel to fall off together is avoided, and the running safety of the vehicle can be improved.
本发明提供了一种车辆的轮端总成、控制方法及车辆,涉及车辆底盘技术领域。轮端总成包括内部中空的轮毂、具有轴的转向节、以及套设在轴上并处于间隙内的至少一个推力滚子轴承和至少一个圆柱滚子轴承,轴位于轮毂的内部并与轮毂的内壁存在间隙,推力滚子轴承的至少部分外壁与轮毂的内壁相贴合,以限制推力滚子轴承沿轴的径向移动,圆柱滚子轴承的外壁与轮毂的内壁相贴合,圆柱滚子轴承的内壁与轴的外壁相贴合。本发明在圆柱滚子轴承发生严重损坏时,轮端总成的轮毂在推力滚子轴承的轴向支撑下,就不会出现轮毂带着车轮一起脱出的情况,可以提高车辆行驶的安全性。
