The invention discloses a coaxial torque vector distribution system which comprises a differential mechanism and a vector motor, a motor shaft of the vector motor is hollowly sleeved on a left half shaft of the differential mechanism, and the motor shaft is in transmission connection with the left half shaft and the differential mechanism through a transmission assembly; the transmission assembly comprises a first planet row and a second planet row, the first planet row and the second planet row share the same planet carrier, a first gear ring of the first planet row is fixedly connected to the left half shaft, and a second gear ring of the second planet row is fixedly connected to the differential mechanism shell. The sun gear of the first planet row or the sun gear of the second planet row is fixedly arranged at the far end of the motor shaft. The differential mechanism has a torque distribution function, the double planet row systems share one planet carrier, and the rotating speed of the planet carrier is lower than that of the differential mechanism shell, so that the dragging torque is smaller, and the performance is higher; meanwhile, the gear ring is adopted for power output, the rotating speed of a transmission assembly of the whole system can be reduced, heat generation is greatly reduced, the problems of oil liquid oxidative deterioration, lubricating performance reduction, aging of rubber sealing pieces and the like are solved, and safety is improved to the maximum extent.

    本发明揭示了一种同轴式转矩矢量分配系统,包括差速器和矢量电机,矢量电机的电机轴空套在差速器左半轴上,所述电机轴与所述左半轴以及差速器之间通过传动组件传动连接;传动组件包括第一行星排和第二行星排,所述第一行星排和第二行星排共用同一行星架,第一行星排的第一齿圈固定连接于所述左半轴,所述二行星排的第二齿圈固定连接于所述差速器壳体,所述第一行星排或第二行星排的太阳轮择一固定设置在所述电机轴的远端。本发明具有转矩分配功能,双行星排系共用一个行星架,且该行星架的转速低于差速器壳体转速,可以使拖曳扭矩更小,性能更强;同时,采用齿圈进行动力输出,可降低整个系统传动组件的转速,大幅度减小热量产生,降低油液氧化变质、降低润滑性能以及橡胶封件老化等问题,最大程度上提高安全性。
