Abstract

The invention relates to the technical field of automobiles, and discloses a dual-motor hybrid power speed control system and a vehicle. The power speed control system comprises an engine, a dual-mass flywheel, a transmission input shaft, a first motor, a first clutch, a one-way clutch, a planet row, an intermediate shaft, a second motor and an output shaft; the planet row comprises a sun gear, a planet gear, a planet carrier and an outer gear ring, and the transmission input shaft penetrates through one end of the motor output shaft and is connected with the outer gear ring; one end of an output shaft of the motor is connected with the sun gear; and an output gear for outputting power is arranged on the planet carrier. The hybrid power system solves the problems that an existing hybrid power system is low in transmission efficiency and large in axial installation space requirement, the play phenomenon can occur during torque coupling and decoupling, all power systems cannot operate independently, the energy recovery efficiency is low, and parking charging cannot be achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a dual-motor hybrid transmission system and a vehicle. Background technique [0002] In the existing hybrid transmission, the motor is integrated on the input or output shaft of the transmission to realize the mixed output of two kinds of power. However, such an arrangement requires a large axial space, and the powertrain needs to be re-arranged; when the engine and motor power are switched and intervened, shocks will occur, which will affect the driving performance. [0003] In addition, in the current hybrid transmission system, the motor cannot play the role of a starter, and cannot realize the function of starting and stopping the engine; since there is only one motor, the motor has to undertake both driving work and power generation work, and the optimal efficiency cannot be guaranteed. The motor drives the start-up control at the same time, which is difficult to contro...
