Problems solved by technology

The series hybrid power system first converts all the power output by the engine into electrical energy by the generator, and then converts the electrical energy into mechanical energy to drive the wheels through the electric motor. Its advantage is that it can realize the optimal control of the engine. Lost too much energy
The parallel system is based on the traditional car transmission system, plus an electric drive system to provide auxiliary power for the car when accelerating or climbing. connection, the engine cannot always work at the high efficiency point
The common hybrid system divides the power from the engine into mechanical and electric paths through a special power distribution device, which can take advantage of the advantages of series and parallel, but the structure is complex and the cost is high. At the same time, the complex transmission mechanism will reduce transmission efficiency

Embodiment Construction

[0020] The dual-rotor hybrid driving device and driving method of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. However, it can be understood that the embodiments described in the specification are only one way of realizing the present invention, and there are many ways that are not described, but are limited in the claims. The purpose of describing the embodiments is to make the present invention more clear, not to limit the scope of protection.

[0021] Such as figure 1 Shown, be provided with engine 1, transmission shaft 3, front axle 9, rear axle 4, the wheel 5 etc. driven by front axle, rear axle in the automobile of the present invention. The crankshaft of the engine 1 is connected with the input shaft 21 of the dual-rotor motor 2 , and the output shaft 27 of the motor is connected with the rear axle 4 through the transmission shaft 3 . Of course, the output shaft 27 can also be c...

Abstract

A dual-rotor mixed power system for the 4-wheel drive car is composed of engine, dual-rotor motor, drive axle, back bridge, inverter, battery set, motor, front bridge and wheels. Said dual-rotor motor consists of input axle, the armature coils and iron core of internal rotor, the permanent-magnet steel and iron core of external rotor, and output axle. Its drive method is also disclosed.

Description

technical field [0001] The invention relates to a drive system of a hybrid electric vehicle, in particular to a hybrid drive system for a four-wheel drive vehicle with a double-rotor motor. Background technique [0002] There are three types of hybrid drive systems: series, parallel and hybrid. The series hybrid power system first converts all the power output by the engine into electrical energy by the generator, and then converts the electrical energy into mechanical energy to drive the wheels through the electric motor. Its advantage is that it can realize the optimal control of the engine. Excessive energy loss. The parallel system is based on the traditional car transmission system, plus an electric drive system to provide auxiliary power for the car when accelerating or climbing. connection, the engine cannot always work at the high efficiency point. The common hybrid system divides the power from the engine into mechanical and electric paths through a special power...
