Driving system of mixed dynamic vehicle

Abstract

A drive system with mixed power for car is composed of engine, motor-generator, the first and the second clutches, input and output planetary gangs, and the first and the second brakes. Its advantages are simple and compact structure, more running modes, and high power performance.

Description

【Technical field】: [0001] The invention relates to an automobile driving system, in particular to a hybrid electric automobile driving system. 【Background technique】: [0002] Since the 1990s, the number of automobiles has increased significantly. The currently widely used fuel engine automobiles have various disadvantages. Statistics show that under the conditions of more than 80% of the roads, an ordinary car only uses 40% of the power potential. The area will also drop to 25%, and what is more serious is that the exhaust gas pollutes the environment; in order to improve fuel efficiency and reduce exhaust emissions, people have developed a car that uses a hybrid power device (Hybrid-Electric Vehicle, abbreviated as HEV). This kind of hybrid device has not only brought into play the advantages of long continuous working time and good dynamic performance of the engine, but also can play the advantages of no pollution and low noise of the electric motor. [0003] According t...

Problems solved by technology

[0002] Since the 1990s, the number of automobiles has increased significantly. Currently, there are various disadvantages in fuel engine automobiles that are commonly used. Statistics show that under the road conditions that account for more than 80%, an ordinary car only uses 40% of its power potential. The area will also drop to 25%, and what is more serious is the pollution of the environment by exhaust emissions; in order to improve fuel efficiency and reduce exhaust emissions, people have developed a car that uses a hybrid power device (Hybrid-ElectricVehicle, abbreviated as HEV)

The disadvantage of this design is that it requires two motors and requires an equal distribution of engine power

This configuration doesn't send all of the engine's power directly to the output shaft making the car's fuel economy lower on the highway than on city roads
