Power generator of motor compressor for automobile air conditioner

Abstract

The invention relates to a power generator of a motor compressor for an automobile air conditioner, which comprises a machine body and a crankshaft and is characterized by further comprising an air-conditioning power generator; a crankshaft belt pulley is arranged on the crankshaft and is installed at the front end of the automobile engine crankshaft; a connecting part of the front end of the automobile engine crankshaft and the crankshaft belt pulley is hollow; a rotor of the air-conditioning power generator is arranged on the inner wall of the hollow part of the crankshaft belt pulley; and a stator of the air-conditioning power generator is arranged at a hollow part at the front end of the automobile engine crankshaft and is arranged on an engine shell. Thus, the power generator has the advantages of fewer accessories between an internal combustion engine and the power generator, simple and compact structure, remarkably shortened longitudinal mounting size, no belt drive, reduced mechanical loss and improved transmission efficiency and is convenient for a vehicle-mounted air-conditioning system conveniently to adopt an overall arrangement structure.

Description

[technical field] [0001] The invention relates to automobiles, in particular to a generator capable of providing electric energy for automobile electric compressors. [Background technique] [0002] In a conventional car, the compressor is belt driven by the engine, so it only runs when the engine is on. The compressor is driven by an engine with constantly changing speeds, and its cooling or heating effect is difficult to control. When the engine stops, the compressor also stops working. This affects the life of the engine on the one hand, because no matter whether the car is waiting or loading or unloading, the engine must be started in order to make the air conditioner run; The engine needs to burn gasoline or diesel or other fuels, and the exhaust gas discharged after combustion has different degrees of pollution, which is not conducive to environmental protection. [0003] The electric compressor in a hybrid car is powered by a separate battery and can operate indepen...

AI Technical Summary

Problems solved by technology

The disadvantages of the split arrangement of the vehicle-mounted air-conditioning system are that the system structure is complicated, and the pipeline of the compressor is very long, which is likely to cause refrigerant leakage and pollute the environment; the structure of the car engine is complex, and the crankshaft pulley needs to drive many accessories, which is prone to failure
