The coaxial type double-motor two-gear electric drive axle based on synchronizer control comprises a first half shaft, a second half shaft, an intermediate shaft, a main drive motor, an auxiliary drive motor and a differential mechanism, and a first-gear driving gear and a second-gear driving gear are fixedly connected to an output shaft of the main drive motor; a first-gear driven gear and a second-gear driven gear which are correspondingly meshed with the first-gear driving gear and the second-gear driving gear are arranged on the intermediate shaft, and a synchronizer is arranged between the first-gear driven gear and the second-gear driven gear; an output shaft of the auxiliary driving motor is fixedly connected with an auxiliary driving gear; an auxiliary driven gear correspondingly meshed with the auxiliary driving gear is arranged on the intermediate shaft; a main reduction driving gear is further arranged on the intermediate shaft and meshed with a main reduction driven gear, the differential mechanism shell is connected with the main reduction driven gear, and the two ends of the differential mechanism are connected with wheels through a first half shaft and a second half shaft. The power performance, the speed performance and the smooth performance of gear shifting are all considered.

    本发明公开了一种基于同步器控制的同轴式双电机两档电驱动桥,包括第一半轴、第二半轴、中间轴、主驱动电机、辅助驱动电机和差速器,主驱动电机的输出轴上固定联接有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对应啮合的一档从动齿轮和二档从动齿轮,一档从动齿轮和二档从动齿轮之间设置有同步器;辅助驱动电机的输出轴上固定联接有辅助主动齿轮;中间轴上设置有与辅助主动齿轮对应啮合的辅助从动齿轮;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,差速器壳体与主减从动齿轮连接,差速器的两端通过第一半轴和第二半轴与车轮连接。本发明兼顾动力性能、速度性能和换档的平顺性能。
