转向




图 2g01520302

液压转向油缸组件 (6) 通过两个可调横拉杆 (5) 与转向节组件 (3) 相连。 转向节组件 (3) 通过主销 (4) 中彼此相对的锥形滚柱轴承在车桥上旋转。

差速器

来自变速箱输出轴的动力通过驱动轴和万向节传输至前桥。 动力通过输入法兰进入前桥。 输入法兰连接在小齿轮上。 动力从小齿轮传输到差速器齿圈。 差速器齿圈用螺栓固定在差速器上。

动力通过小齿轮和侧齿轮经差速器传输。 侧齿轮用花键连接到车桥轴上。 有关差速器的更多信息,请参阅系统操作, "差速器"。

终传动

典型终传动和车桥

终传动和车桥的部件

(1) 行星齿轮

(2) 齿圈

(3) 法兰

(4) 壳体

(5) 销

(6) 车桥轴

(7) 万向节

(8) 太阳齿轮和轴

(9) 托架

动力通过车桥轴 (6) 和万向节 (7) 传输到终传动。 终传动会进行动力传动系中最后一次降速增扭。 终传动包括下述部件:太阳齿轮 (8) 、托架 (9) 、行星齿轮 (1) 和齿圈 (2) 。 太阳齿轮 (8) 通过万向节 (7) 接合到车桥轴 (6) 上。 齿圈 (2) 用花键固定到壳体 (4) 上。 四个行星齿轮 (1) 安装在托架 (9) 中。 托架 (9) 通过螺栓固定到法兰 (3) 上。 法兰 (3) 通过两个相对的锥形滚柱轴承在壳体 (4) 上旋转。

动力通过太阳齿轮 (8) 传输到行星齿轮 (1) 。 行星齿轮 (1) 绕着齿圈 (2) 内侧旋转。 行星齿轮 (1) 环绕齿圈 (2) 的移动导致托架 (9) 和法兰 (3) 旋转。 动力从法兰 (3) 传输到车轮。
