ISG (integrated starter generator) motor and hybrid power drive system with same

Abstract

The invention provides an ISG (integrated starter generator) motor. The ISG motor comprises a shell, a stator, a rotor, a rotating shaft, two bearings, a front end cover and a rear end cover. The ISG motor is a disc-type motor, the rotating shaft is a hollow shaft, and the disc-type motor also comprises a separation plate, a ball-cage constant-speed coupler and a rotary transformer. The invention also provides a hybrid power drive system with the ISG motor. The hybrid power drive system comprises an engine, a car clutch, a drive motor, a transmission shaft driving axle and a control assembly, the engine is sequentially connected with the car clutch, the drive motor and the transmission shaft driving axle, the engine is coaxially and integrally installed with the car clutch and the drive motor, the ISG motor is connected with the engine by virtue of the ball-cage constant-speed coupler, and the ISG motor and the engine are coaxially installed in a splitting manner. The ISG motor is small in size, small in occupied installation space and small in weight, an additional set of flywheel and flywheel shell is not needed, the axial length is reduced, and the problems caused by the arrangement of a belt transmission device such as low transmission efficiency, high oil consumption and complicated structure of the drive system can be avoided.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering, and in particular relates to an ISG motor and a hybrid drive system with the ISG motor. Background technique [0002] At present, the passenger and freight vehicles owned by the society are mostly conventional vehicles. With the application of a large number of automotive electrical equipment, such as eddy current retarders, electric air conditioners, engine electric thermal management systems and various automotive electronic equipment, etc., The power consumption is more than ten kilowatts. At present, conventional automobiles often need to install multiple conventional automobile generators driven by belts to meet the electricity demand. However, the power generation efficiency of traditional automobile generators is only about 50%, and multiple generators need to be installed, resulting in difficult and complicated engine room layout, reduced reliability and increased maintenance ...

Problems solved by technology

[0007] The object of the present invention is to provide an ISG motor with a hollow shaft, a separator, a spherical cage constant velocity coupling and a rotary transformer, and an ISG motor with the ISG motor and the ISG motor and the motor through the ball A hybrid drive system connected by a cage constant velocity coupling and installed coaxially and separately, aiming at solving the problems caused by the general motor occupying installation space in the prior art and when the ISG motor is coaxially installed at different positions behind the engine The mechanical strength of the shell is high, the shell wall is thick, and an additional flywheel and flywheel shell are added, resulting in the problem of large axial space in the drive system and the need to increase the belt drive when the ISG motor is installed in parallel with the engine. The problem of low belt transmission efficiency, high fuel consumption and the complex structure of the drive system caused by the device is brought by the belt tensioning mechanism.
