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.
