The invention relates to an axle system. The axle system includes a planetary gear set. Theplanetary gear set comprises a first sun gear, a first planet gear which is meshed with the first sun gear, a second planet gear which is in anti-torque connection with the first planet gear in the same rotation axis, a ring gear which is arranged coaxially with the first sun gear, a planet carrier which is mounted on the second planet gear and arranged coaxially with the first sun gear, and a second sun gear which is engaged with the second planet gear and arranged coaxially with the first sun gear. The torque of the axle system can be input into the planetary gear set from the first sun gear and can be selectively output through the planet carrier or the second sun gear. According to the axle system, the two-stage speed change function with the large transmission ratio can be achieved through simple and compact layout.

    本发明涉及一种车桥系统。该车桥系统包括行星齿轮组,行星齿轮组包括:第一太阳轮;与第一太阳轮啮合的第一行星轮;与第一行星轮同旋转轴线地抗扭连接的第二行星轮;与第一太阳轮同旋转轴线地布置的齿圈;安装在第二行星轮上并与第一太阳轮同旋转轴线地布置的行星架;和与第二行星轮啮合并与第一太阳轮同旋转轴线地布置的第二太阳轮;其中,车桥系统的扭矩能够从第一太阳轮输入行星齿轮组,并能够选择性地通过行星架或第二太阳轮输出。本发明的车桥系统能够以简单紧凑的布局实现具有较大传动比的二级变速功能。
