The invention relates to a transmission mechanism and a double-motor electric drive axle assembly. The transmission mechanism comprises a first input shaft and a second input shaft, a sun gear of the first planetary reducer is connected with a first input shaft and a second input shaft, a planet carrier serves as an output end, and the second input shaft is connected with the sun gear through a first one-way transmission part and connected with the planet carrier through a one-way transmission structure. The second input shaft rotates in the first rotating direction, transmits power to the sun gear through the first one-way transmission piece and disconnects power transmission with the one-way transmission structure, and the second input shaft rotates reversely, transmits power to the planet carrier through the one-way transmission structure and disconnects power transmission with the sun gear. When the second input shaft rotates in the first rotation direction or rotates in the reverse direction, the rotation directions of the planet carriers are the same. The power requirements of high-speed driving and climbing working conditions can be met, the power of a single motor is low, the highest rotating speed of the motor is low, the falling point of an efficient area tends to be consistent with the working condition point of the whole vehicle, and the utilization rate of the efficient area is high.
本发明涉及一种传动机构及双电机电驱桥总成,机构包括:第一输入轴和第二输入轴;第一行星减速器,其太阳轮与第一输入轴和第二输入轴连接,行星架为输出端,第二输入轴通过第一单向传动件与该太阳轮连接,通过单向传动结构与该行星架连接,第二输入轴沿第一转动方向转动通过第一单向传动件传递动力至该太阳轮,并断开与单向传动结构之间动力传递,第二输入轴反向转动通过单向传动结构传递动力至该行星架,并断开与该太阳轮之间动力传递,且第二输入轴沿第一转动方向转动或者反向转动时,该行星架转动方向相同。本申请可满足高速行车和爬坡工况的动力需求,单个电机功率较低,电机最高转速低,高效区落点与整车工况点趋于一致,高效区利用率高。
