The invention discloses a vehicle transmission device, a vehicle drive system and a vehicle. The vehicle transmission device comprises a speed reduction mechanism, and the speed reduction mechanism comprises an input gear, an output gear and a transmission gear ring, wherein the input gear is suitable for being connected with a power source, and the output gear is used for outputting power; and the speed reduction mechanism further comprises a first diverting gear set and a second diverting gear set, wherein the input gear, the output gear, the first diverting gear set and the second divertinggear set are arranged in the transmission gear ring, the first diverting gear set meshes with the input gear and the transmission gear ring, the second diverting gear set meshes with the input gear and the transmission gear ring, and the output gear meshes with the transmission gear ring. According to the vehicle transmission device, the first diverting gear set and the second diverting gear setcan divert power input by the input gear, the gear local stress is effectively reduced, the whole structure is compact, and the bearing capacity is high.
Description
technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a vehicle transmission, a vehicle drive system with the vehicle transmission and a vehicle with the vehicle drive system. Background technique [0002] The vehicle drive system of an automobile includes a vehicle transmission device, which is generally used to reduce the speed and increase the torque of the power output by the power source, and further output it to the hub of the wheel. In the related technology, the ring gears of the reduction mechanism of the vehicle transmission are relatively concentrated, and the rigidity and strength of the ring gears are high, and the distance between the input and output shafts is too small, and the speed ratio range of the reduction mechanism is small, which is not conducive to the selection of power sources and layout. Contents of the invention [0003] The present invention aims to solve at least one of the technical p...
