The invention discloses a parallel shaft type double-motor two-gear electric drive axle based on clutch control, which comprises an input shaft, an intermediate shaft, a half shaft, a main drive motor, an auxiliary drive motor and a differential mechanism, a first-gear driving gear, a gear shifting clutch and a second-gear driving gear are sequentially arranged on the input shaft, and the gear shifting clutch is connected with the first-gear driving gear and the second-gear driving gear; a first-gear driven gear and a second-gear driven gear which are meshed with the first-gear driving gear and the second-gear driving gear in a one-to-one correspondence manner are arranged on the intermediate shaft; a main reduction driving gear is further arranged on the middle shaft and meshed with a main reduction driven gear, a differential mechanism is connected with the main reduction driven gear, and the two ends of the differential mechanism are connected with wheels through half shafts respectively. Through ingenious combination of the two motors and the two gears, output or recovery of torque and rotating speed in different working modes is achieved, and therefore the requirements of different working conditions of a vehicle are met.

    本发明公开了一种基于离合器控制的平行轴式双电机两档电驱动桥,包括输入轴、中间轴、半轴、主驱动电机、辅助驱动电机和差速器,主驱动电机和辅助驱动电机均与输入轴连接,输入轴上依次设置有一档主动齿轮、换档离合器和二档主动齿轮,换档离合器连接一档主动齿轮和二档主动齿轮;中间轴上设置有与一档主动齿轮和二档主动齿轮一一对应啮合的一档从动齿轮和二档从动齿轮;中间轴上还设置有主减主动齿轮,主减主动齿轮与主减从动齿轮啮合,差速器与主减从动齿轮连接,差速器的两端分别通过半轴与车轮连接。本发明通过两个电机和两个档位的巧妙组合,实现不同的工作模式下扭矩与转速的输出或回收,从而满足车辆不同工况的需求。
