The invention discloses a novel parking brake assembly. The invention belongs to the technical field of parking braking. The novel parking brake assembly comprises a structural body, a protection cover is arranged at the top of the structural body; a protection shell is arranged at the bottom of the protection cover, a piston rod is arranged in the middle of the inner side of the protection shell,a limiting assembly is arranged at the bottom of the piston rod, movable plates are rotatably connected to the two ends of the inner side of the protection shell, and rotating rods are rotatably connected to ends of the two movable plates. The piston rod moves upwards and drives a limiting plate to move upwards; the limiting plate upwards extrudes the bottoms of the movable plates; the movable plates incline upwards by taking the rotating rods as base points; the movable plates move downwards away from the limiting assembly and extrude brake blocks to move downwards, the rotating rods serve as center lines, the side, close to the limiting assembly, of the limiting plate is twice that of the other side of the limiting plate, the extrusion of the movable plates to the brake blocks is more labor-saving by means of the separation of a lever, and the brake efficiency in parking brake is better.

    本发明公开了一种新驻车制动总成,属于驻车制动技术领域,包括结构主体,所述结构主体的顶部设置有保护罩,所述保护罩的底部设置有保护壳,所述保护壳内侧的中间位置处设置有活塞杆,所述活塞杆的底部设置有限位组件,所述保护壳内侧的两端皆转动连接有活动板,两组所述活动板的一端皆转动连接有转动杆。本发明通过使活塞杆向上移动并带动限位板向上移动,使限位板向上挤压活动板的底部,使活动板以转动杆为基点向上倾斜,使活动板远离限位组件的位置向下移动,并挤压制动块向下移动,且以转动杆为中心线,使限位板靠近限位组件的一侧是另一侧的两倍,利用杠杆的远离,使活动板对制动块的挤压更为省力,使驻车制动中的制动效率更好。
