A vehicle brake system (2) and a vehicle including the vehicle brake system (2). In the vehicle brake system (2), a friction disc (21) and an outer ring (22o) of a thrust bearing are fixed together with a rim assembly (11) of a wheel (1) in the circumferential direction, and an inner ring (22i) of the thrust bearing faces an inner ring (13i) of a wheel bearing. When the brake assembly abuts against the friction disc (21), on one hand, friction torque generated between the brake assembly and the friction disc (21) can enable the rotating speed of the rim assembly (11) and the rotating speed of the wheel (1) to be reduced, and therefore the braking effect is achieved; on the other hand, the (axial) pressure applied to the friction disc (21) by the braking assembly is transmitted to the inner ring (13i) of the wheel bearing through the thrust bearing instead of being transmitted to the outer ring (13o) of the wheel bearing, so that the phenomenon that the outer ring (13o) and the inner ring (13i) generate relative displacement in the braking process of the wheel bearing is avoided, and the service life of the wheel bearing is prolonged. Over-abrasion and noise generated in the braking process are reduced or even eliminated.
一种车辆用制动系统(2)和包括车辆用制动系统(2)的车辆。在该车辆用制动系统(2)中,通过将摩擦盘(21)和推力轴承的外圈(22o)与车轮(1)的轮辋组件(11)在周向上固定在一起并且推力轴承的内圈(22i)与车轮轴承的内圈(13i)相对。当制动组件与摩擦盘(21)抵接在一起时,一方面,制动组件与摩擦盘(21)之间产生的摩擦力矩能够使得轮辋组件(11)及车轮(1)的转速降低,从而实现制动作用;另一方面,制动组件对摩擦盘(21)施加的(轴向)压力将经由推力轴承传递到车轮轴承的内圈(13i),而不会传递到车轮轴承的外圈(13o),从而避免了车轮轴承在制动过程中出现外圈(13o)和内圈(13i)产生相对移位的现象,减小甚至消除了在制动过程中产生的过磨耗和噪声。
