Problems solved by technology

[0004] However, this technology has difficulties in the surface treatment process, which is likely to cause low accuracy of the surface roughness and flatness of the parts, and because the aluminum alloy itself is easy to bond, when the oxide film fails, it is easy to cause jamming between the swash plate and the sliding shoe. hysteresis, so it is necessary to propose a new type of swash plate with stable process and excellent effect to meet the requirements of compressor operation

Embodiment Construction

[0015] Please refer to figure 2 As shown, the swash plate 10 in this embodiment is a composite structure with a matrix 11 and two surface layers 12a, 12b. The material of the matrix 11 is, for example, 45# steel, and the material of the two surface layers 12a, 12b is copper alloy. The main components of the copper alloy are calculated by weight, including 78-82% of copper, 9-11% of lead and 9-11% of tin. This composite structure is made, for example, by powder metallurgy sintering technology, which has the characteristics of low cost and high performance, and the parts made have a certain porosity, and are often used in the manufacture of self-lubricating materials. The main process of powder metallurgy sintering technology includes sintering and pressing the powdered copper alloy on the substrate made of 45# steel by adopting the process of "pre-sintering → pre-pressing → deep-sintering → fine-pressing → final-sintering". The temperature of the deep sintering process reache...

Abstract

The present invention relates to a swash plate in swash plate compressor, which includes a basal body with two sides of the basal body provides with a superficial layer, wherein material of each superficial layer is copper alloy, and weight percentage is as following: copper 78-82%, lead 9-11% and tin 9-11%. The superficial hardness of the compound structure swash plate is lower than that of hard anodic oxidation aluminum alloy surface in prior art, better lubricating property, and more suitable to assort with steel quantity to form sliding friction pairs.

Description

technical field [0001] The invention relates to a swash plate compressor in an automobile air-conditioning system, in particular to a swash plate of the swash plate compressor. Background technique [0002] Such as figure 1 As shown, a swash plate type variable displacement compressor usually has a swash plate member 8 which is integrally connected with a drive shaft 9 . The swash plate member 8 rotates integrally with the drive shaft 9 and is inclined relative to the drive shaft 9 . Piston 3 engages with swash plate member 8 via a pair of shoes 6 . The drive shaft 9 rotates and reciprocates the piston 3 through the belt swash plate member 8 and the shoe 6 . The variable displacement of the compressor is adjusted by the change of the inclination angle of the swash plate member 8 relative to the X direction of the drive shaft 9 . [0003] The base material of the swash plate is usually made of iron-based materials, copper alloys, aluminum alloys or composite materials of ...
