Abstract

The present invention relates to a bidirectional swashplate type fixed-displacement automotive air-conditioning compressor. In the adopted technical scheme, the air-conditioning compressor comprises a clutch, a front cover, a front cylinder, a rear cylinder and a rear cover; wherein, a front valve plate is mounted between the front cover and the front cylinder; a rear valve plate is mounted between the rear cover and the rear cylinder; a main shaft is mounted in the front and the rear cylinders; via a front thrust bearing and a front needle bearing, the front end of the main shaft is connected with the clutch after passing through the front cover, and the other end of the main shaft is connected with the rear cylinder via a rear thrust bearing and a rear needle bearing; a swashplate is mounted on the main shaft; the outer edge of the swashplate is mounted in a notch in the middle of a double-headed piston; ball sockets are arranged in the notch in the middle of the double-headed piston; two semispheres are mounted in the ball sockets; the planes of the semispheres are contacted with the swashplate; the spherical surfaces of the semispheres are contacted with the two ball sockets of the double-headed piston; a layer of polyfluortetraethylene coating is attached on the outer diameter of the double-headed piston. The air-conditioning compressor has the advantages of compact designed structure, high working efficiency and reliability, and good sealing effect.

Description

Technical field: [0001] The invention belongs to an air-conditioning compressor on an automobile, in particular to an air-conditioning compressor for an automobile with a bidirectional swash plate type fixed displacement. Background technique: [0002] Most of the existing air-conditioning compressors for automobiles work in one direction, and the working efficiency of the compressor is low; piston rings must be installed on the outer diameter of the piston, which makes the structure of the piston complicated, the friction coefficient between the piston and the cylinder increases, and the reliability of the compressor is poor; and There is only one valve plate in the compressor, and the sealing effect of the sealing surface of the valve plate is poor. With the requirement and improvement of the power performance of automobiles, people pay more and more attention to the comfort and economy of automobile air conditioners. The design technology and structural characteristics o...
