Electromechanical hybrid power mobile automatic transmission drive system

Abstract

An electromechanical hybrid power mobile automatic transmission drive system is designed as an integral, which only comprises 29 main parts and can generate 6 forward gears and 1 reverse gear. Since a motor is arranged on an input shaft integrally, the whole motor has a synchronous speed with the input shaft. The motor has the functions of a generator and can drive a vehicle to travel by utilizing counterforce generated by the generator field, so as to generate electricity when an automobile travels, the automobile engine power is not additionally consumed due to the load of the generator when electricity is generated while the automobile travels, thereby reaching the energy-saving purpose. When a hybrid power driving pattern is used, a clutch and a brake are not required for gear changing during the vehicle is started or driven, thus realizing stepless speed changing and large torque transmission.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to an automatic transmission transmission system of an electromechanical hybrid electric vehicle. Background technique [0002] As the world's oil resources continue to decrease, and with the increasing awareness of environmental protection in countries around the world, energy saving and emission reduction of automobiles is the theme of today's development. The most environmentally friendly car is an electric car, but the mileage of electric cars is limited, so hybrid power has been developed. Automobiles, hybrid electric vehicles will become the mainstream of automobile development. [0003] After searching the existing automobile patent technology literature, it is found that the current technical problems of hybrid electric vehicles are as follows: [0004] First, the transmission system of the existing hybrid electric vehicle has not achieved integration, resu...

AI Technical Summary

Problems solved by technology

[0004] First, the transmission system of the existing hybrid electric vehicle has not achieved integration, resulting in scattered parts of the transmission system, causing the installation and connection between the transmission devices to occupy a limited space on the vehicle, for example: patent ZL200820033442.6 hybrid electric vehicle The power transmission system, for example: patent ZL200720123450.5, a driving system of an all-wheel drive hybrid electric vehicle, has the above technical problems

[0005] Second, the transmission system of the existing hybrid electric vehicle has no continuity in the speed change, and has never fully realized the stepless speed change. Usually, the process of speed change transmission can be completed only by exchanging two working elements. For example: patent ZL200710034415.0 electric mechanical planetary mechanism Continuously variable transmission systems, such as the patent ZL200710078132.6 dual planetary multi-mode hybrid electric vehicle transmission system, have the above technical problems

[0006] Third, the transmission system of the existing hybrid electric vehicle usually adopts a planetary gear train, a certain element of the planetary gear train is driven by the engine, and a certain element of the planetary gear train is driven by an electric motor, and the two driving speeds jointly drive the gear of the planetary gear train. For the output element, since the two driving speeds are not at the same starting point, if the engine speed increases, the motor speed must also increase to achieve the purpose of common driving. If there is an error in the coordination of the two driving speeds, it will cause energy loss

[0007] Fourth, the power supply system of the existing hybrid electric vehicle cannot meet the power supply demand of the motor for a long time. When the car is driving on the highway, if the power is exhausted, the car can only run at medium and low speeds

[0008] Fifth, the transmission mechanism of the continuously variable automatic transmission used in the existing automobiles usually adopts the friction transmission between the transmission steel belt and the transmission pulley, which has the advantages of simple structure and high transmission efficiency, but its disadvantage is that it cannot transmit large torque
