AI Technical Summary

Problems solved by technology

This not only greatly increases the number of connecting parts, reduces the connection strength, but also deteriorates the coaxiality of the system
On the engine with high-speed rotation and high torque output, it not only reduces the reliability of the system, but also increases the installation size and cost of the system

Embodiment Construction

[0014] Further illustrate the present invention in conjunction with accompanying drawing.

[0015] As shown in FIG. 2 , FIG. 2 is a structural schematic diagram of an integrated starter-generator installed with a resolver proposed by the present invention. Among them, 1-engine body, 2-engine crankshaft flange, 3-ISG stator body, 4-ISG stator winding, 5-ISG rotor permanent magnet, 6-ISG rotor body, 7-resolver stator connection plate, 8-rotary Variable stator winding, 9-resolver rotor core, 10-clutch friction plate, 11-clutch pressure plate, 12-clutch housing, 13-clutch output shaft.

[0016] The ISG rotor body (6) is fixed on the engine crankshaft flange (2) by screws, and a permanent magnet (5) is installed inside the ISG rotor body. The ISG stator winding (4) is fixed on the ISG stator (3), and the ISG stator is fixed on the engine body (1) by screws. The resolver rotor (9) is fixed directly to the ISG rotor body, between the rotor body and the engine. The resolver stator ...

Abstract

In the invention, a ISG rotor block is secured on the flange of engine crankshaft through bolt; in the ISG rotor block there is a permanent magnet mounted; ISG stator is secured on the engine block; a rotating transformer rotor is directly secured on the ISG rotor block and is located between the rotor block and engine block; the rotating transformer stator winding and ISG stator block are secured on the engine block together through resolver stator coupling pad, and are located between the stator block and the engine; the outside of ISG rotor block is a plane used for securing the clutch housing and the compacting clutch plate which is closely coupled with the clutch compressing disc so as to output the power to the clutch output shaft.

Description

technical field [0001] The invention relates to an integrated starter generator containing a rotary transformer, belonging to the technical field of engine components. Background technique [0002] Hybrid electric vehicle technology adds a motor to the power system driven solely by the engine for electric auxiliary drive, thereby effectively reducing the fuel consumption and harmful emissions of the vehicle. The integrated starter generator (the integrated starter generator, referred to as ISG) hybrid system is a hybrid configuration widely used in small vehicles such as cars and SUVs, which combines the engine flywheel and the motor into one , the flywheel of the original engine is replaced by the motor rotor, the flywheel shell is replaced by the motor stator, and the motor is integrated into the original flywheel position of the engine. Due to the close combination of the two, the motor and the engine are collectively referred to as the ISG hybrid engine. [0003] The m...
