Embodiment Construction

[0035] The present invention is described in detail below in conjunction with accompanying drawing:

[0036] The object of the present invention is to provide a four-wheel-drive hybrid electric system, that is, to provide a four-wheel drive hybrid electric system with a planetary row as a coupling device. The invention can realize the decoupling of the engine speed and torque, control the engine in the optimum working range, and improve the fuel economy of the engine. At the same time, the four-wheel drive mode can greatly improve the dynamic performance of the car and maximize the braking energy recovery potential of the car. The four-wheel drive oil-electric hybrid system of the present invention can realize four-wheel drive through the front drive of the engine and the rear drive of the hub motor, and realize the four-wheel drive running of the vehicle with high comprehensive transmission efficiency and fuel economy of the whole vehicle.

[0037] refer to figure 1 , the f...

Abstract

The invention discloses a four-drive oil-electricity hybrid power system. The four-drive oil-electricity hybrid power system aims to overcome the problem that a current four-drive vehicle is high in oil consumption and serious in emission and is incapable of realizing optimal control for an engine with parallel type four-drive hybrid power. The four-drive oil-electricity hybrid power system comprises a motor, a battery, an engine, a planet row, a first clutch, a second clutch, a motor controller, a rear right wheel hub motor, a first wheel hub motor controller, a second wheel hub motor controller and a rear left wheel hub motor, wherein three connectors of the motor are connected with three connectors of the motor controller through electric wires; positive and negative pole connectors of the motor controller are connected with positive and negative pole connectors of the battery through electric wires; positive and negative pole connectors of the first wheel hub motor controller are connected with positive and negative pole connectors of the battery through electric wires; positive and negative pole connectors of the second wheel hub motor controller are connected with positive and negative poles of the battery through electric wires; three connectors of the first wheel hub motor controller are connected with three connectors of the rear right wheel hub motor through electric wires; three connectors of the second wheel hub motor controller are connected with three connectors of the rear left wheel hub motor through electric wires.

Description

technical field [0001] The invention relates to a power system of a hybrid electric vehicle, more precisely, the invention relates to a four-wheel drive hybrid electric system. Background technique [0002] In order to alleviate the current energy shortage and the increasingly serious environmental pollution, energy saving and environmental protection have become the only way for the development of automobiles. Hybrid electric vehicles have been widely recognized for their outstanding low fuel consumption and practicality, and their drive systems have three forms: series, parallel and hybrid. Series connection can achieve the optimal control of the engine, but the energy loss is relatively large; parallel connection can achieve better transmission efficiency, but the mechanical connection between the engine and the output shaft cannot ensure that the engine is always in a better working area; hybrid connection can combine series and The advantages of parallel connection and...
