Variable-frequency speed control motor for hybrid electric vehicle

Abstract

The invention provides a variable-frequency speed control motor for a hybrid electric vehicle, which belongs to the technical field of hybrid electric vehicle motors, and driving couple and clutch devices, and mainly aims to solves the problems that the service life of an auxiliary power motor shaft adopting the conventional structure is seriously influenced due to great impact, and accident potentials exist. The variable-frequency speed control motor is mainly characterized by comprising a main power motor, an auxiliary power motor and a driving couple and clutch device; a second shaft sleeve, a second release fork, a second shift lever, a second release arm and a second release bearing seat are arranged at the rear end of the auxiliary power motor; and the second release arm is coupled with a second cylinder arranged on the auxiliary power motor. The variable-frequency speed control motor has the characteristic that when the auxiliary power motor shaft is in the state of being probably impacted, the second cylinder completes the specified action to enable a clutch to be in a semi-disengaging state to eliminate the rotational speed difference, so as to reduce the load of the auxiliary power motor shaft, and is mainly used for hybrid electric vehicles.

Description

technical field [0001] The invention belongs to the technical field of motors, drive couplings and clutch devices of hybrid electric vehicles. Specifically relates to a frequency conversion speed regulation motor for a hybrid electric vehicle. Background technique [0002] A hybrid vehicle is a vehicle that combines an internal combustion engine and an electric motor, and is powered by a mixture of gasoline (diesel) oil, gas and electricity. It has the characteristics of high efficiency and low pollution, and meets the requirements of modern automobile development. In recent years, the world Major car companies have launched their own hybrid vehicles. Since the hybrid electric vehicles in the world are used in conjunction with the variable frequency speed regulation motor and the engine, and the frequency conversion speed regulation motor is connected between the engine and the transmission, there are the following deficiencies: First, it takes up too much vehicle space due...

Problems solved by technology

Since the hybrid electric vehicles in the world are used in conjunction with the variable frequency speed regulation motor and the engine, and the frequency conversion speed regulation motor is connected between the engine and the transmission, there are the following deficiencies: First, it takes up too much vehicle space due to the increase of the motor. The internal space will increase the weight of the car, and at the same time slow down the response speed and reduce the reliability of the car; secondly, due to the limitation of the engine structure and the space inside the car, the engine and transmission need to be redeveloped and designed, the development cycle is long, and the existing Internal Combustion Engine Vehicles Going Hybrid

This structure has been tested by the actual vehicle driving, and it is found that the auxiliary power motor shaft will be greatly impacted, which will seriously affect the service life of the auxiliary power motor shaft, and there are potential accidents
