The invention relates to the technical field of vehicle braking, and provides a brake adjusting assembly, a brake device and a brake device. The brake adjusting assembly comprises a first rocker arm, a cam part and an escapement mechanism, the cam part and the escapement mechanism are both installed on the first rocker arm, and the escapement mechanism is used for synchronously moving with the first rocker arm so as to drive the cam part to move in the brake direction; the escapement mechanism comprises an escapement piece and a ratchet wheel piece, the escapement piece is clamped on the ratchet wheel piece, and when the first rocker arm moves to a preset area, the escapement piece is used for releasing the ratchet wheel piece so as to drive the cam piece to rotate by a preset angle, and therefore the initial position of the cam piece moving in the braking direction is adjusted. And during next braking, the cam piece moves from the new initial position to the braking direction, so that the abrasion of the brake shoe can be compensated, the movement stroke of the first rocker arm during braking is not increased, and the braking effect of the brake shoe is not influenced.
本发明涉及车辆制动技术领域,提供刹车调节组件、刹车装置及制动装置。刹车调节组件包括第一摇臂、凸轮件和擒纵机构,凸轮件和擒纵机构均安装在第一摇臂上,擒纵机构用于与第一摇臂同步移动,以驱动凸轮件向制动方向移动;擒纵机构包括擒纵件和棘轮件,擒纵件卡合在棘轮件上,在第一摇臂移动至预设区域时,擒纵件用于释放棘轮件,以驱动凸轮件转动预设角度,从而调节凸轮件向制动方向移动的初始位置。下一次刹车时,凸轮件从新的初始位置向制动方向移动,从而可以补偿刹车蹄块的磨损,不会增加第一摇臂刹车时的运动行程,不影响刹车蹄块的制动效果。
