The automobile parking brake shoe assembly comprises a back plate and a brake drum, a brake shoe is rotationally arranged on the back plate, and a first driving piece used for driving the brake shoe to deflect in the direction close to the inner side wall of the brake drum is arranged on the back plate; the back plate is further provided with a first elastic piece used for driving the brake shoe to deflect in the direction away from the inner side wall of the brake drum. A shoe plate is slidably arranged on the brake shoe, a friction plate is fixedly arranged on the shoe plate, a positioning plate is slidably arranged on the brake shoe in the axial direction of the brake drum, a transmission part used for driving the positioning plate to slide is arranged on the brake shoe, and a second elastic part used for driving the shoe plate to slide in the direction away from the brake shoe is arranged on the brake shoe. The friction plate is used for abutting against the positioning plate, and a limiting assembly used for preventing the shoe plate from sliding is arranged on the brake shoe. The method has the advantages that the braking response time can be controlled within a relatively stable interval, so that the possibility of traffic accidents caused by untimely braking is greatly reduced.
本申请涉及一种汽车驻车制动蹄总成,其包括背板和制动鼓,背板上转动设置有制动蹄,背板上设置有用于驱使制动蹄向靠近制动鼓内侧壁的方向偏转的第一驱动件,背板上还设置有用于驱使制动蹄向远离制动鼓内侧壁的方向偏转的第一弹性件;制动蹄上滑动设置有蹄板,蹄板上固定设置有摩擦片,制动蹄上沿制动鼓的轴向滑动设置有定位板,制动蹄上设置有用于驱使定位板滑动的传动件,制动蹄上设置有用于驱使蹄板向远离制动蹄方向滑动的第二弹性件,且摩擦片用于抵接定位板,制动蹄上设置有用于阻止蹄板滑动的限位组件。本申请具有刹车的响应时间能够控制在一个相对稳定的区间内,从而大大降低了因刹车不及时而引发交通事故的可能的效果。
