The invention discloses a hybrid transmission with a high-speed self-disengaging function, which comprises an input shaft; a low-speed intermediate shaft; a high-speed intermediate shaft; a transmission mechanism arranged among the input shaft, the low-speed intermediate shaft and the high-speed intermediate shaft; an auxiliary motor directly connected with the input shaft; a coupling device arranged between the auxiliary motor and the engine; a driving motor having a motor shaft arranged on the outer side of the input shaft in a sleeving mode and always meshed with a combination gear arrangedon the high-speed intermediate shaft in a sleeving mode through a transmission gear, wherein the combination gear is provided with a self-disengaging device, and the self-disengaging device and a high-speed gear synchronizer arranged on the high-speed intermediate shaft are mutually exclusive. It is ensured that the driving motor does not participate in driving any more after the vehicle speed exceeds the regulation limit vehicle speed, the engine is prevented from dragging the driving motor to idle through inertia, and consumption of extra energy is avoided; and in a pure electric driving mode, the two motors can work at the same time to provide electric driving force.
本发明揭示了一种具有高速自脱功能的混动变速器,包括:输入轴、低速中间轴和高速中间轴,设置在三者之间的传动机构,以及一辅助电机,所述辅助电机与所述输入轴直接连接;一耦合装置,所述耦合装置设置在所述辅助电机与所述发动机之间;一驱动电机,其电机轴空套于所述输入轴的外侧,所述电机轴通过传动齿轮与空套在所述高速中间轴上的结合齿轮始终啮合;所述结合齿轮上设置有自脱开装置,所述自脱开装置与设置在所述高速中间轴上的高速挡同步器互斥。本发明确保超过法规限制车速后驱动电机不再参加驱动,防止发动机拖着驱动电机的惯量空转,避免了额外能量的消耗;并且在纯电动驱动模式下,两个电机可以同时工作提供电驱动力。
