Description
Technical field
The utility model relates to a kind of air condition compressor on automobile-used, is a kind of Vehicular air-conditioner compressor specifically.
Background technique
Automobile air conditioner compressor is the heart of automobile air conditioning system, plays a part compression and refrigerant conveying steam.The sloping plate type vehicle air condition compressor is little with its volume, light weight, be easy in narrow and small engine compartment to install and arrange and widely use.
A kind of automobile air conditioner compressor is disclosed at present; It comprises transmission shaft, is fixed on the connection set between swash plate, piston and said swash plate and the piston on the described transmission shaft; One end of connection set for piston on the sphere that is complementary of ball-and-socket, another section is positioned at the plane that swash plate is complementary.Between this model utility connection set and the swash plate is the plane, and the frictional force in the to-and-fro motion between the two is big, is worn easily.In addition in the motion axially load increase, axial displacement takes place in axle easily, and is of long duration, zero device does not match, operate insufficient, thereby influence working efficiency easily; Moreover steel ball is extruded the back and recovers slow, also can cause to-and-fro motion to have some setbacks.
The model utility content
To the problems referred to above, it is a kind of simple in structure that the utility model provides, and reduces the friction factor that produces in the to-and-fro motion, protects the Vehicular air-conditioner compressor of each zero device.
The utility model is realized through following technological scheme: a kind of Vehicular air-conditioner compressor, comprise main shaft, protecgulum, cylinder head, cylinder body, and described front-end of spindle stretches out protecgulum; Rear-end of spindle in cylinder body connects swash plate, and the forward thrust bearing is set between described protecgulum and the swash plate, and the back thrust-bearing is set between described swash plate and the planet plate; Described planet plate is connected with piston action through connecting rod, between described cylinder body and the cylinder head valve board assembly is set, and positioning bearing also is set in the described cylinder body; Described positioning bearing and main spindle's are right; Said positioning bearing front end is embedded with steel ball, and described steel ball another part is embedded in the planet plate, and groove is offered at the later half position of positioning bearing; In the described groove locking device is set, described locking device is connected with steel ball.
As preferably, described locking device comprises strut and spring, and described strut links to each other spring with steel ball.
As preferably, described connecting rod is a spherical connecting bar.
As preferably, cylinder gasket is set also between described cylinder body and the valve board assembly.
As preferably, between described valve board assembly and the cylinder head gland shim is set.
As preferably, described main shaft is provided with asphalt felt at the protecgulum front end.
The utility model has taked above-mentioned corrective measure to carry out, and its beneficial effect is remarkable: the first, and the utility model adopts spherical connecting bar, can reduce friction factor at connecting rod and planet plate, the wearing and tearing that produce when reducing to-and-fro motion, and motion is flexibly; The second, at protecgulum and swash plate the forward thrust bearing is set, all be equipped with the back thrust-bearing between swash plate and the planet plate, it can bear thrust load and prevent the axial displacement of axle, guarantees the proper functioning of compressor, has prolonged the working life of each zero device; The 3rd, the spring recovery capability is good, can promote steel ball to be returned to next motion state fast; The 4th, set up cylinder gasket and gland shim and can fill up the microscopic void between cylinder body and the cylinder head, guarantee that there is good sealing property at the junction plane place, and then prevent cylinder leakage tester.
