The utility model is mainly used in car air conditioner, a kind of variable swash plate displacement automobile air-conditioning compressor.
Background technique
At present, in domestic automobile industry, joint brand depot air condition compressor used is variable swash plate displacement automobile air-conditioning compressor.This kind of structure air condition compressor is main flow.There is good market.The air condition compressor of this kind of form that domestic automobile manufacturer is used is the external manufacturing or the domestic assembling of foreign technology.Domestic autonomous Design less.And abroad the variable swash plate displacement automobile air-conditioning compressor of this kind of form or structure are comparatively loaded down with trivial details, or technological requirement is too high, high expensive.The purpose of this utility model is to overcome the existing deficiency of existing automobile air conditioner compressor, enhances productivity, and reduces costs, and has therefore designed the inclined disc type internal control compressor with variable displacement of a kind of two body
Summary of the invention
The inclined disc type internal control compressor with variable displacement of two bodies, mainly by drive plate assembly (3), belt pulley assembly (4), coil assembly (8), protecgulum (39), push-plate (36), swash plate body (32), sliding plate (31), axle sleeve (33), main shaft (25), have strong market potential (34), cylinder body (27), piston (26), valve plate assembly (17), bonnet (19), control valve (37) forms.It is characterized in that processing straight trough after main shaft (25) and push-plate (36) interference fit, straight trough position localized quench hardening is processed, endoporus is that spherical swash plate body (32) screws rear composition swash plate assembly with the sliding plate (31) of Cuprum alloy material, with profile be spherical axle sleeve Spielpassung, swash plate assembly and axle sleeve can relative Arbitrary Rotations, axle sleeve (33) endoporus coordinates with gap of main reinforcement again, axle sleeve can slide along main shaft main line, by have strong market potential (34), make swash plate assembly and main shaft push-plate assembly be connected to become main shaft swash plate assembly, having strong market potential with swash plate body earhole is interference fit, having strong market potential with push-plate straight trough is Spielpassung, push-plate ear face and swash plate body ear face Spielpassung, make swash plate assembly not have relative rotation with push-plate, hollow coated piston coordinates with swash plate assembly clearance by a pair of hemisphere, piston coordinates with cylinder interporal lacuna, by oil film, seal.When being subject to axial force, axle sleeve slides along axis, and having strong market potential of being connected with the interference of swash plate assembly can only be slided along push-plate straight trough, makes swash plate assembly change angle, and realizing hollow coated piston stroke can change, and compressor displacement can change.Shaft seal device and front needle bearing are equipped with in protecgulum inside, and cylinder body is equipped with rear needle bearing, front and back needle bearing supports main shaft swash plate assembly, thrust-bearing and pad before and after axially having, the certain load of the given front and back of dish-like reed thrust-bearing.Between cylinder body and protecgulum, between cylinder body and valve plate assembly, between valve plate assembly and bonnet, all there is gasket seal to seal, high-pressure decompression valve and control valve and collar are housed on bonnet, suction valve chip is after valve plate assembly and cylinder body between gasket seal, locating stud makes them have certain position relationship, and stay bolt makes them form a pump housing.
Accompanying drawing explanation
Spindle screw (1), pad (2) is adjusted in gap, drive plate assembly (3), belt pulley collar (4), belt pulley assembly (5), shaft seal device collar (6), shaft seal device (7) coil assembly (8), coil collar (9), front needle bearing (10), forward thrust is selected pad (11), forward thrust bearing (12), forward thrust Gaskets (13), stay bolt (14), suction valve chip (15), gasket seal after cylinder body (16), valve plate assembly (17), bonnet gasket seal (18), bonnet (19), dish reed (20), rear bearing seat ring (21), back pressure roller bearing (22), rear bearing seat ring (23), rear needle bearing (24), main shaft (25), piston (26), cylinder body (27), hemisphere (28), straight pin (29), gasket seal (30) before cylinder body, sliding plate (31), , swash plate body (32), axle sleeve (33), the axle (34) of having strong market potential, spring (35), push-plate (36), control valve (37), control valve collar (38), protecgulum (39)
Embodiment
Push-plate and swash plate body be cast blank first, adopts at present investment pattern precision casting, quenching with Subsequent tempering, and then push-plate blank is delivered machine and is added workshop and carry out the processing of lathe, machining center machinery and clean, and finally turns heat and adds workshop Quenching Treatment.Sliding plate is manufactured by external coordination producer, after 45 steel processing, carries out surface treatment.In assembly process, increase a press machine, double inclined plane push-plate is connected by the interference of having strong market potential with two body swash plates.All the other component are all existing normal process.The utility model beneficial effect is: simplify the structure, implement conveniently, improved efficiency of assembling, further reduced cost of production, improved economic benefit.
