Embodiment Construction

[0060] figure 1 A hybrid system for an 4WD hybrid vehicle with a one-way clutch is shown in . As shown in the figure, the hybrid system includes a power unit, a one-way clutch A, a transmission case, a differential, a drive shaft A and a drive shaft B, a braking system, an energy storage device, a hybrid accessory, and a hybrid control system Wait. The power plant includes an internal combustion engine, motor A and motor B. Motor A may be an ISG motor. The variable speed transmission includes a variable speed transmission A and a variable speed transmission B for the drive shaft A and the drive shaft B, respectively. The speed change transmission case A and the speed change transmission case B can be respectively connected to the drive shaft A and the drive shaft B through a differential. Transmission case A together with the differential forms a first drive train for driving shaft A, while transmission case B together with the differential forms a second drive train for d...

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...
