Description
Technical field
The present invention relates to a kind of piston bindiny mechanism of compressor of automotive air conditioning system.Particularly relate to a kind of tilted-plate compressor.This semicircle steel ball and piston shoes combination physical efficiency is improved the frictional behavior of friction means of the swash plate-piston shoes-piston of tilted-plate compressor.
Background technique
The swash plate of the tilted-plate compressor of existing automotive air conditioning system and slipping-shoe device majority as shown in Figure 5, it is made up of piston 4, two steel balls 1, two piston shoes 2, swash plate 3 and cylinder bodies 5.Described two steel balls are parallel to be embedded in two hemisphere face grooves of inner chamber both sides of piston, and an end face of described piston shoes is set to sphere, and the inner ball surface of described piston shoes matches with steel ball; Another end face of described piston shoes is set to the plane, between the working plane of described two piston shoes, set a rotating swash plate, described swash plate has two working surfaces that are parallel to each other 7,8, one endoporus 6 that forms an angle with the inclined working of swash plate is arranged in the middle of the swash plate, this endoporus 6 is connecting the transmission shaft (not shown) and is driving the swash plate rotation, does reciprocating linear motion in cylinder thereby promote piston.The material of piston generally adopts aluminum alloy to make, and swash plate generally adopts the material of iron-based to make.
Above-mentioned structure piston shoes in use born should with the swash plate friction of iron-based material, again with the operating conditions of the both surface friction of the steel ball friction of base steel material; Very easily wear and tear simultaneously at (be generally 16 kilograms per centimeter square more than) piston shoes under the operating mode of heavy duty, in addition normal for the fault of piston shoes fracture occurring, influence the reliability and the operating life of tilted-plate compressor work thus.
Summary of the invention
Purpose of the present invention is exactly in order to overcome above-mentioned deficiency of the prior art, and tilted-plate compressor that a kind of novel semicircle steel ball and piston shoes are combined into one in new ways, operating conditions is changed into single-sided friction by both surface friction is provided.
The objective of the invention is by providing a kind of tilted-plate compressor with following structure to realize, it comprises the forward and backward piston that connects one and the front and rear cylinder that matches with described forward and backward piston, swash plate and two semicircle steel balls, two piston shoes; Swash plate is connected with transmission shaft, and piston shoes place on the bi-side of swash plate.
Described piston shoes have round boss, described half rounds spherical zone has circular groove, described round boss and described circular groove match and are integrated, described semicircle steel ball is configured in the hemisphere face groove of inner chamber both sides of front and rear portions of the described forward and backward piston brace rod neck that connects as one, an end face of described piston shoes is set to the plane, between the working plane of described two piston shoes, set a swash plate, described swash plate has two working surfaces that are parallel to each other, and can slide between the working plane of two piston shoes.
Above-mentioned semicircle steel ball and piston shoes are combined into one in new ways, thereby described piston shoes operating conditions is changed into piston shoes working plane and swash plate working plane single-sided friction by the both surface friction of the sphere of the sphere of original piston shoes working plane and swash plate working plane, piston shoes and steel ball, eliminated between the sphere of the sphere of described piston shoes and described steel ball friction phenomenon mutually, thereby avoided under any operating mode described piston shoes and described worn steel ball or block and cause the generation of tilted-plate compressor damage accident.Meanwhile, described piston shoes are middle male structure by original concave structural change, and described piston shoes rigidity is strengthened widely, and promptly its bearing capacity obtains greatly to improve.
The ball that described semicircle steel ball employing hardness is HRC42～65 half-and-half cuts rear center and processes.Described piston shoes employing silicone content is 12～22% high silica-alumina material.The rigid material that described swash plate adopts is an iron.Owing to semicircle steel ball and piston shoes with the new form friction phenomenon mutually that is combined into one between the sphere of the sphere of having eliminated piston shoes and steel ball, therefore from the friction condition that the aspect had both satisfied the hemisphere face groove of described semicircle steel ball and piston of choosing of material, can satisfy the friction requirements between described piston shoes and the swash plate again.
Semicircle steel ball of the present invention also is applicable to central authorities that are arranged in solid piston and the one-piece cylinder that matches with described solid piston with the structure of piston shoes assemblying body.
Compared with prior art, the invention has the advantages that: 1. semicircle steel ball and piston shoes composite unit structure can make that the working speed of tilted-plate compressor increases, compression ratio increases, thereby improved the reliability and the operating life of tilted-plate compressor; 2. the material of semicircle steel ball, piston and piston shoes is chosen the aspect more selection field, and can fully satisfy friction requirements separately.
