In sum, the present invention is by carrying out anodizing to swash surfaces, thereby forms stable, the firm patina of one deck in its surface.A kind of antiwear additive liquid of infiltration in the patina coating, can play anticorrosive, wear-resistant, adiabatic effect, effectively reduced the possibility that adhesive wear and interlock take place between swash plate outer surface and the crawler shoe, thereby improved the sliding capability of the surface of contact of swash plate and crawler shoe, prolonged the working life of oblique tray type compressor.
Description of drawings
In order to further specify concrete structure of the present invention and effect thereof, the present invention is described in detail below in conjunction with the drawings and specific embodiments, wherein:
Fig. 1 is the sectional view of oblique tray type compressor of the present invention; And
Fig. 2 is the tectal schematic representation that covers on the swash plate matrix.
Embodiment
Below with reference to description of drawings preferred embodiment of the present invention, wherein represent identical parts with identical label, wherein:
1 magnetic clutch; 2 live axles; 3 protecgulums; 4 drive lid; 5 articulated mechanisms; 6 swash plates; 7 pistons; 8 crawler shoes; 9 cylinder blocks; 10 valve board assemblies; 11 low-pressure cavity; 12 cylinder heads; 13 control valves; 14 hyperbaric chambers; 15 crankshaft cavities; 16 screws; 17 coatings; 18 matrixes
At first see also Fig. 1, this figure is the sectional view of oblique tray type compressor of the present invention.
Oblique tray type compressor of the present invention comprise cylinder block 9, the protecgulum 3 of cylinder block 9 one ends and be arranged on cylinder block 9 and protecgulum 3 between crankshaft cavity 15.The other end of cylinder block 9 also is provided with valve board assembly 10, control valve 13 and cylinder head 12, and they are linked into an integrated entity by screw 16 respectively.
Oblique tray type compressor also is provided with a piston 7, and this piston 7 is with live axle 2 rotation, and by be installed in swash plate 6 on the live axle 2 in the crankshaft cavity 15 and crawler shoe 8 in casing bore upper dead center and lower dead centre between to-and-fro motion.
To narrate the running of oblique tray type compressor of the present invention below.
Vehicle motor drives live axle 2 rotations by magnetic clutch 1, and swash plate 6 is made unitary rotation by drive plate 4 and articulated mechanism 5 with live axle 2.The rotation of swash plate 6 is converted to the straight reciprocating motion of each piston 7 in corresponding casing bore by crawler shoe 8.The to-and-fro motion of piston 7 is drawn into the refrigerant gas in the low-pressure cavity 11 in the casing bore, and the gas in casing bore is discharged to it in hyperbaric chamber 14 when being compressed to predetermined pressure.When the rotating speed of the heat load of vaporizer or compressor changes, control valve 13 passages in the cylinder head 12 open and close operation, thereby the pressure in the crankshaft cavity 15 are changed, and make the angle of inclination of swash plate 6 that respective change take place and change the stroke of piston 7.Utilize said method, can make the discharge capacity of compressor controlled, guarantee the discharge capacity regulatory function of oblique tray type compressor and stablizing of vehicle refrigeration amount by this by changing suction pressure.
For the surface of contact of the swash plate that solves oblique tray type compressor and crawler shoe is easy to take place the problem of stuck phenomenon, oblique tray type compressor of the present invention has adopted the swash plate 6 that is coated with one deck coating 17 on swash plate matrix 18.
See also Fig. 2 below, the figure shows the coating 17 that is coated on the swash plate matrix 18.As shown in Figure 2, swash plate 6 is made of matrix 18 and coating 17.In the present embodiment, matrix adopting Al-Si base aluminum alloy (for example eutectic or hypereutectic Al-Si base aluminum alloy) is made, and its composition comprises the Si of 12-30%, and surplus is Al (impurity is no more than 0.5%).After alloy matrix aluminum being carried out the hard anodizing processing, the surface of matrix 18 has formed stable, the firm patina of one deck, and this patina is the coating 17 in the present embodiment.
In another preferred embodiment, the composition of matrix also comprises the Cu of 0.5-10% and the Mg of 0.1-2%.
In addition, can also utilize the porosity of the patina on swash plate 6 surfaces, a kind of antiwear additive liquid of infiltration in the patina coating 17 on swash plate 6 surfaces, this antiwear additive liquid is a kind of phosphorous three component rare earth compounds, this rare earth compound is made up of rare earth and organophosphorated salt, and the main component of its rare earth is holmium, dysprosium, lutetium and europium etc.For the adhesion property that makes 17 pairs of rare earth compounds of patina coating improves, should make the particle of rare earth compound tiny as far as possible.Find that by test the particle diameter size is the most suitable between the 0.002-0.003 millimeter.
For antiwear additive is infiltrated through in the hole of patina as much as possible, should reduce the surface tension of this antiwear additive liquid, to quicken the capillary phenomenon of hole.Therefore, can also in antiwear additive liquid, add a kind of high-speed osmotic agent.Rely on this high-speed osmotic agent that rare earth compound is permeated in the hole of the alumina molecule that is adsorbed on aluminium alloy matrix surface.In the present embodiment, used high-speed osmotic agent is a kind of non-ionic surfactant agent---alkyl phenolic group polyoxyethylene phosphate (PEO phosphate ester).
In addition, consider effective absorption of 17 pairs of rare earth compounds of patina coating, it is considerable that antiwear additive evenly covers on the surface of patina coating 17.Therefore, can also in antiwear additive liquid, add a kind of dispersing agent.In the present embodiment, used dispersing agent is a kind of non-ionic surfactant agent a---polyoxyethylene aliphatic alcohol ether.
In addition, find that by test the thickness of the coating 17 on swash plate 6 surfaces is preferably the 0.001-0.1 millimeter.
All by sample manufacturing and checking (type approval test and bench simulation performance test), it is respond well for above scheme.
Though below in conjunction with the embodiments purpose of the present invention, structure and effect have been done to further specify, those skilled in the art will be appreciated that, the foregoing description only is used for illustrating, and can not be as to restriction of the present utility model.Therefore, can in connotation scope of the present invention, carry out modification to embodiment, these modification comprise: use have oblique tray type compressor double-head piston, fixed displacement replace having single head pison, variable-displacement oblique tray type compressor or the like, they all will drop within the scope of appending claims of the present invention.
