Abstract

The invention discloses a swivel arm structure of automobile air conditioner compressor. The swivel arm structure includes a swivel arm main body provided with a central hole and fixed on a main shaft via the central hole, the central hole is in interference fit with the main shaft, two parallel spaced bosses are arranged outwards at one side of the swivel arm main body, the boss is correspondingly provided with a pin shaft hole, and a pin shaft passes through the pin shaft hole to connect the swivel arm main body with a swash plate on the main shaft. According to the invention, the swivel arm structure of automobile air conditioner compressor is connected with the swash plate on the main shaft by the simple pin shaft mechanism, and the central hole and the main shaft are in interference fit, to realize simple structure, convenient assembly, high applicability and high safety and reliability.

Description

technical field [0001] The invention relates to an automobile air-conditioning compressor, in particular to a rotating arm structure of the automobile air-conditioning compressor. Background technique [0002] In the refrigeration system of the automobile air conditioner, the change of the general variable displacement rotary disc compressor is based on the change of the angle of the swash plate on the main shaft. Usually, when the compressor is at low speed or high load, the swash plate In the state of maximum angle, that is, when the piston runs to the maximum stroke, on the contrary, when the compressor is at high speed or low load, the swash plate is in the state of minimum angle, that is, when the piston runs to the minimum stroke. [0003] The rotating arm is the main component of the variable displacement rotary disc compressor. The rotating arm of the traditional automotive air-conditioning compressor has the disadvantages of complex structure, inconvenient assembly ...
