Frequency control motor and generating set for hybrid vehicle

Abstract

The present invention relates to a hybrid power vehicle used frequency-conversion speed-regulation electric motor and a generator set thereof. The invention belongs to the technical field of electric motor, driving coupling and engaging and disengaging device of the hybrid power vehicle. The invention mainly settles the problem that the power is not efficient and the storage battery is easily to lack of electricity when the hybrid power vehicle uprises as a single set of frequency-conversion speed-regulation electric motor is adopted. The invention is mainly characterized in that the electric motor comprises a main power electric motor, an accessory power electric motor and a driving coupling and engaging and disengaging device. The back-end cover of the main power electric motor is coupled with the front-end cover of the accessory power electric motor. A flange is fixed on the shaft of the electric motor of the main power electric motor. A sleeve, a release yoke, a deflector rod and a release arm are provided at the back end of the main power electric motor. The release arm is coupled with a cylinder arranged on the main power electric motor. The motor axis which is at front end of the accessory power electric motor is provided with a flywheel hub and a flywheel, and the clutch is fixed on the fly wheel. The invention has the characteristics of larger hybrid power output and strong electricity generating capacity, and is mainly used for the hybrid power vehicle.

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 regulating motor and a generator set for a hybrid 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), 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 frequency-variable speed-regulating motor and the engine, and the frequency-variable speed-regulating motor is connected between the engine and the gearbox, there are the following deficiencies: First, it takes up too much space due to the ...

Problems solved by technology

Since the hybrid electric vehicles in the world are used in conjunction with the frequency-variable speed-regulating motor and the engine, and the frequency-variable speed-regulating motor is connected between the engine and the gearbox, there are the following deficiencies: First, it takes up too much space due to the increase of the motor. The interior space of the car increases the weight of the car, and at the same time slows down the response speed and reduces the reliability of the car; secondly, due to the limitation of the engine structure and the space inside the car, the engine, gearbox, etc. need to be redeveloped and designed, the development cycle is long, and it cannot be adjusted Hybrid retrofitting of existing internal combustion engine vehicles

Due to the limited power output and power generation capacity of a single variable frequency speed regulating motor, hybrid vehicles have the problems of insufficient power when going uphill and the battery is prone to power loss.
