The invention discloses a three-gear hybrid transmission adopting double long-wheelbase motors. The three-gear hybrid transmission comprises an input shaft, an intermediate shaft, a transmission mechanism between the input shaft and the intermediate shaft, a differential mechanism, a first motor and a second motor, and the first motor and the second motor are high-speed, high-efficiency and long-wheelbase motors with the same wheelbase; a self-disengaging device is arranged on the input shaft, and the self-disengaging device and a high-speed gear synchronizer arranged on the input shaft are mutually exclusive. The three-gear hybrid transmission has the main beneficial effects that the two motors with the same size and specification are adopted, so that the cost of the transmission is greatly reduced; the self-disengaging device is adopted, it is guaranteed that the first motor does not participate in driving any more after the vehicle speed exceeds a regulation limit vehicle speed, thefirst motor is prevented from being dragged by an engine to idle, and consumption of extra energy is avoided.
本发明揭示了一种采用双长轴距电机的三挡混动变速器,包括:输入轴,中间轴,两者之间的传动机构,差速器,以及第一电机和第二电机,所述第一电机和第二电机采用具有相同轴距的高速高效长轴距电机;所述输入轴上设置有自脱开装置,所述自脱开装置与设置在所述输入轴上的高速挡同步器互斥。本发明的有益效果主要体现在:采用两个尺寸、规格相同的电机,使变速器的成本大大降低;采用自脱开装置,确保超过法规限制车速后第一电机不再参加驱动,防止发动机拖着第一电机的惯量空转,避免了额外能量的消耗。
