The invention discloses an axle and box integrated drive axle. A planetary reducer is mounted in an axle body and comprises a transmission gear set, a first-stage planetary assembly and a gear ring; a half shaft respectively penetrates through a first-stage sun gear, a first-stage planet carrier and a gear ring of the first-stage planet assembly; in the working process, a driving motor drives the first-stage sun gear in a meshed mode through the transmission gear set, the first-stage sun gear drives the first-stage planet gear in a meshed mode, and the first-stage planet gear drives the first-stage planet carrier to rotate; and the first-stage planet carrier directly or indirectly drives the half shaft to rotate through the differential mechanism, and the effects of speed reduction and torque increase are achieved. The planetary reducer is adopted, the peripheral external space of the half shaft is utilized, and compared with a traditional multi-stage gear transmission scheme adopting a large gear ratio, a smaller gear can be adopted, so that the width in the radial direction is reduced, and the size of the whole axle and box integrated drive axle is reduced.

    本发明公开一种桥箱一体式驱动桥,桥体中安装行星减速器,行星减速器包括传动齿轮组、一级行星总成和齿圈;半轴分别从一级行星总成的一级太阳轮和一级行星架以及齿圈中间穿过;工作时,驱动电机通过传动齿轮组啮合驱动一级太阳轮,一级太阳轮啮合驱动一级行星轮,一级行星轮带动一级行星架转动;一级行星架直接或者间接地通过差速器带动半轴转动,实现了降速增矩的效果;本发明采用行星减速器,利用了半轴周向的外部空间,相对于传统的采用大齿比的多级齿轮传动方案,可以采用更小的齿轮,从而减小了径向方向的宽度,整个桥箱一体式驱动桥的尺寸得以降低。
