前轮 (3) 连接到壳体 (5) 上。 两个锥形滚柱轴承支持此连接。 壳体 (5) 不转动。 板 (9) 不转动。 盘 (8) 随着前轮 (3) 转动。

制动器冷却机油流入油道 (C) ,并冷却盘 (8) 和板 (9) 。 此后,制动器冷却机油流过出口油道 (E) 。 接着,制动器冷却机油流回液压油箱。

利用测压口 (A) 排出行车制动器液压系统的空气。 利用油道 (B) 中的塞排出停车制动器液压系统的空气。

停车制动器接合

停车制动器由弹簧接合,通过机油压力释放。 接合停车制动器时,泵压力不输送至油道 (B) 。 机油压力不输送至储油室 (13) 。 弹簧 (11) 推压活塞 (12) 。 活塞 (12) 推动活塞 (7) 。 活塞 (7) 将盘 (8) 和板 (9) 推压在一起。 将盘 (8) 和板 (9) 推到一起时就会产生摩擦。 摩擦阻止车轮组件 (3) 转动。

释放停车制动器时,泵压力不输送至油道 (B) 。 接着,机油流入储油室 (13) 。 加压油推动活塞 (12) 以压缩弹簧 (11) 。 弹簧 (15) 和弹簧导座 (14) 将活塞 (7) 从盘 (8) 和板 (9) 推开。 盘 (8) 和板 (9) 将不再接触,而停车/辅助制动器将会得到释放。

行车制动器接合

接合行车制动器或减速器时,机油压力输送至油道 (D) 。 接着,机油流入储油室 (6) 。 随着机油压力升高,活塞 (7) 将盘 (8) 和板 (9) 推到一起并产生摩擦。 摩擦导致前轮 (3) 的转速降低。 继续接合行车制动器或减速器会使前轮 (3) 停止转动。

释放行车制动器时,机油压力不流入油道 (D) 或储油室 (6) 。 弹簧 (15) 和弹簧导座 (14) 将活塞 (7) 从盘 (8) 和板 (9) 推开。 盘 (8) 和板 (9) 将不再接触,而行车制动器将会得到释放。
