The invention discloses a dual-motor multi-gear series-parallel hybrid power transmission which comprises an engine, a first motor, a second motor, a parallel shaft gear set and three pairs of synchronizers needed for gear shifting. The parallel shaft gear set comprises an input shaft and an output shaft which are arranged in parallel; the engine is connected with the input shaft, and a synchronizer S1 is arranged on the input shaft; the output shaft is provided with a synchronizer S2, a synchronizer S3, a gear G1, a gear G2, a gear G3 and a gear G4. According to the hybrid power transmission, the engine has four speed ratios, and gear shifting can be achieved without power interruption under the HEV working condition; the two motors respectively have two gears, and gear shifting can be achieved without power interruption under the EV working condition; under the EV working condition, the two motors can be driven simultaneously, and the motor torque, the power requirement, the cost, the weight and the like are reduced; and the EV working condition and the HEV working condition can be smoothly switched.

    本发明公开一种双电机多挡串并联混合动力变速器,包括发动机、第一电机、第二电机、平行轴齿轮组、换挡所需的三对同步器;平行轴齿轮组包括平行设置的输入轴和输出轴;发动机与输入轴连接,输入轴上设有同步器S1;输出轴上设有同步器S2、同步器S3、齿轮G1、齿轮G2、齿轮G3和齿轮G4。本发明混合动力变速器中,发动机有四个速比,HEV工况可无动力中断换挡;两个电机分别具有两个挡位,EV工况可无动力中断换挡;EV工况两个电机可以同时驱动,降低电机扭矩、功率需求以及成本、重量等;能够实现EV和HEV工况相互平顺地切换。
