行驶马达可拆分为以下三个总成:

  • 旋转总成由以下部件构成:驱动轴 (1), 滑块 (5), 挡圈 (6), 套筒 (7), 导杆 (18), 隔套 (19), 弹簧 (20) 和 活塞 (21) 。

  • 停车制动器由以下部件构成:活塞导向环 (8), 制动器先导阀 (12), 摩擦盘 (22), 分隔板 (23), 制动器弹簧 (26) 和 制动器活塞 (27) 。

  • 油量切换阀由以下部件构成:活塞 (3), 单向阀 (9), 单向阀 (10), 活塞 (17) 和 油量切换阀 (34) 。

泵输送的机油流量取决于行驶方向。 泵输送的机油经过孔口 (30) 或孔口 (31) 流进行驶马达。 泵油受力,经过孔口 (31) 或 (30) 流出行驶马达。

箱体排油经过马达盖 (15) 的排流口 (29) 流回液压油箱。

在向前行驶过程中,惰轮泵输送的机油经过孔口 (30) 流进左行驶马达。 机油从孔口 (30) 流过马达盖 (15) 的油道 (11) 和配流盘 (14) 的油道 (25) 。 然后,机油流过套筒 (7) 的油道 (24) ,并推动活塞 (21) 向左移动。

滑块 (5) 连接在活塞上。 滑块 (5) 和活塞在旋转斜盘 (4) 表面从上止点向下止点滑动。 滑块 (5) 和活塞还随套筒 (7) 旋转。 惰轮泵供应的机油经过配流盘 (14) 的油道 (25) 流进活塞 (21) 。 机油通过活塞 (21) 的油道 (11) 排出。 然后,机油流过配流盘 (14) 的油道 (35) 。 接下来,机油流过孔口 (31) 。 套筒逆时针转动。

驱动轴 (1) 通过花键连接到套筒 (7) 。 左行驶马达的轴和套筒逆时针旋转,以向前行驶。

在向后行驶时,孔口 (30) 用作回油口。 而孔口 (31) 用作供油口。 左行驶马达顺时针旋转。

当驱动泵通过孔口 (30) 向右行驶马达输送机油时,右行驶马达顺时针转动以向前行驶。 当驱动泵输送的机油流过孔口 (31) 时,右行驶马达逆时针转动以向后行驶。
