The invention discloses a longitudinally-arranged rear-drive transmission of a hybrid electric vehicle. The longitudinally-arranged rear-drive transmission comprises a range-extending power generation mechanism, a clutch and a parallel speed reduction mechanism. According to the longitudinally-arranged rear-drive transmission of the hybrid electric vehicle, coaxial arrangement is adopted, the generator and the driving motor are coaxially arranged, the structure is simple, the power transmission route is stable, and the manufacturing cost is low; the range-extending power generation mechanism is provided with two-stage speed increasing, and high power generation efficiency can be achieved; the parallel speed reduction mechanism is provided with two-stage speed reduction and one-stage speed increase, in the engine parallel drive working mode, speed reduction is conducted after one-stage speed increase, the engine drive rotating speed is reduced, the engine can drive a vehicle in parallel at the medium vehicle speed, and the fuel economy and the whole vehicle NVH performance are improved; the input shaft penetrates through an inner hole of a generator shaft, and the clutch output shaft penetrates through an inner hole of a driving motor shaft, so that the whole transmission structure is compact, and is suitable for vehicle types such as light trucks or pickup trucks.

    本发明公开了混合动力汽车纵置后驱变速器,包括:增程发电机构、离合器和平行减速机构。本发明提供的混合动力汽车纵置后驱变速器,采用同轴式布置,发电机和驱动电机同轴设置,结构简单,动力传递路线稳定,制造成本低;增程发电机构设置两级增速,能够实现较大的发电效率;平行减速机构设置两级减速和一级增速,在发动机并联驱动工作模式下,先经过一级增速再减速,降低了发动机驱动的转速,使发动机可以在中等车速实现并联驱动车辆,提升了燃油经济性和整车NVH性能;输入轴穿过发电机轴内孔设置,离合器输出轴穿过驱动电机轴内孔设置,使整体传动结构紧凑,适用于轻卡或皮卡等车型。
