Hybrid system of four-wheel drive hybrid car with one-way clutch

Abstract

The invention relates to a hybrid system of a four-wheel drive hybrid car with a one-way clutch. The system comprises a plurality of power plants, which include an internal-combustion engine, a first motor, a second motor, the first transmission system, a second transmission system, a brake system, wherein the first motor is connected with a first drive shaft through the first transmission system; the second motor is connected with a second drive shaft through the second transmission system; the brake system is associated with the first drive shaft and the second drive shaft, a hybrid accessory, a hybrid control system, an energy storage device which provides energy to the hybrid control system and the hybrid accessory, and a one-way clutch, which is connected between a crank of the internal-combustion engine and the first motor. The hybrid control system controls the one-way clutch to build or cut off the connection between the crank of the internal-combustion engine and the first motor.

Description

technical field [0001] The invention relates to a hybrid power system of a four-wheel drive hybrid electric vehicle with a one-way clutch. Background technique [0002] With the further aggravation of energy shortage and global warming, energy saving and emission reduction have become the focus of attention all over the world. Governments and automobile companies in various countries have accelerated the research and development of new energy vehicles. [0003] At present, the pure electric driving of four-wheel drive hybrid electric vehicles on the market can only be driven by the drive shaft where the drive motor is located, and it is impossible to realize the pure electric drive of the front and rear drive shafts and the pure electric drive at the same time, which leads to the inability of the motor to fully exert its power performance and brake recovery. Energy is also limited. [0004] Authorized patent CN201002503Y relates to a driving system of an all-wheel drive hy...

AI Technical Summary

Problems solved by technology

In this kind of hybrid power system, it is difficult to realize the idle stop function, the engine still works in the working mode of a traditional car, and it is impossible to realize the pure electric drive of the front wheels, and it is impossible to realize the pure electric drive of the four wheels at the same time. The energy is limited, and the energy storage of the power battery is insufficient, so that the motor cannot fully exert its power performance
