停车制动器操纵杆

(1) 停车制动器操纵杆

(2) 停车制动器锁定释放操纵杆

停车制动杆位于座椅右侧。 向上拉起停车制动器操纵杆 (1) ,以接合停车制动器。 压下释放操纵杆 (2) 并向下推停车制动器操纵杆,以分离停车制动器。

停车制动器位于驱动轴和后桥之间。 制动力是通过操纵杆和拉线组件手动促动。

停车制动器的部件和位置

(3) 制动盘

(4) 电缆

(5) 弹簧

(6) 操纵杆

(7) 卡尺

(8) 制动衬片

制动钳 (7) 用螺栓固定到后桥上。 制动片 (3) 连接到后桥中的小齿轮上。 制动片 (3) 在制动钳 (7) 中旋转。

当停车制动器接合时,拉线 (4) 拉动操纵杆 (6) 。 操纵杆 (6) 旋转。 操纵杆 (6) 连接到凸轮上,这将迫使制动衬片 (8) 抵住制动片 (3) 。

当停车制动器分离时,弹簧 (5) 辅助拉线 (4) ,且拉线 (4) 使操纵杆 (5) 返回到分离位置。 此动作会从制动片 (3) 上释放制动衬片 (7) 。
