Problems solved by technology

The shortcoming of ordinary compressors is that after the electromagnetic coil is energized, the pulley and the suction cup will continuously attract and cause a lot of noise and wear, which will seriously affect the normal operation of the compressor.
When the compressor is stuck due to damage, the compressor pulley and the engine pulley cannot stop the transmission, and the damage to the belt drive cannot be avoided
Moreover, using an electromagnetic clutch, the mass of the compressor is large and the manufacturing cost is high

Abstract

The invention relates to an air conditioning compressor for automobiles, which comprises a front cover, a cylinder body and a back cover, wherein a valve plate assembly is arranged between the cylinder body and the back cover; a driving shaft extends out of the front cover; the end part of the driving shaft is provided with a belt pulley; the belt pulley comprises a belt roller which is rotatablely installed on the front cover; the shaft end of the driving shaft is provided with a driving disk; an overload protector is arranged between the driving disk and the belt roller; and the overload protector comprises a spring piece and a torque limiting piece. In the belt pulley of the invention, the belt roller and the driving shaft of the compressor are combined into an integral body through the torque limiting piece, and the compressor runs all the times with no joint impact and low noise, thereby eliminating the torque fluctuation and enhancing the comfort; when the compressor is stuck due to damage, the torque limiting piece deforms to disengage, and the belt roller is disconnected with the driving disk, thereby avoiding the damage of the belt transmission and performing the functionof overload protection; and in addition, since the weight of the belt roller without a clutch is reduced, the power consumption of the compressor is lowered, thus, the invention has the advantage of low cost.

Description

technical field [0001] The invention relates to an automobile air conditioner, in particular to an automobile air conditioner compressor. Background technique [0002] The automobile air-conditioning compressor is driven by the automobile engine, and generally adopts a belt drive, and a pulley connected by a belt is respectively installed on the engine and the compressor. In order to protect the compressor, an electromagnetic clutch is arranged between the compressor pulley and the compressor drive shaft, and when the compressor is overloaded, the connection between the compressor pulley and the compressor drive shaft can be disconnected. [0003] The automobile air-conditioning compressor clutch is composed of pulley, suction cup, electromagnetic coil, etc., and its types include disc armature type, spring leaf type, etc. Its working principle is that the connection or disconnection of the air conditioner compressor is controlled by the electromagnetic clutch, and the elec...
