Abstract
The utility model relates to an oblique plate type compressor with variable discharge capacity. A crank shaft cavity is arranged between a gas cylinder body and a front cover. A driving shaft is supported by a bearing which is positioned between the front cover and the gas cylinder body, and is provided with a driving rod, an oblique disc and a planetary disc. The planetary disc is hinged with one end of the connecting rod, and the other end of the connecting rod is hinged with the piston in the gas cylinder body. The driving rod is clamped with a left driving seat surface and a right driving seat surface. Pins are inserted and fixed in circular holes which are arranged on the centers of the left driving seat surface and the right driving seat surface, and thus the pins can optionally slide in an entire kidney-shaped hole of the driving rod. The single driving seat surface of the oblique disc is changed into double driving seat surfaces, and the utility model guarantees that the compressor can be used when the compressor rotates in the left direction and the right direction, and satisfies operation requirements of users on different rotation directions.
Description
The utility model relates to car air conditioner, the driving seat surface on the variable displacement Wobble plate type refrigerant compressor in particularly a kind of automotive air-conditioning system.
Existing variable displacement oblique tray type compressor is when normal the use, its sense of rotation needs orientation, because vehicle difference, the user just has different demands to the use rotation direction of compressor, if any customer requirements left-handed, the user who has then requires dextrorotation, if sense of rotation is got wrong, will cause variable compressor inner impaired and cause losing efficacy, can not normally use.Existing compressor has only the function of single rotation direction, i.e. dextrorotation or left-handed.
The purpose of this utility model provides a kind of variable displacement oblique tray type compressor, and it makes the swash plate list drive seat surface and changes over two seat surfaces that drive, and can use to guarantee the rotation of compressor left and right directions.
A kind of variable displacement oblique tray type compressor described in the utility model, between cylinder block and protecgulum, crankshaft cavity is set, live axle is by the bearing supporting that is arranged in protecgulum and cylinder block, driveshaft, swash plate and planetary plate are installed on the live axle, one end of planetary plate and connecting rod is hinged, the other end of connecting rod and the piston hinge in the cylinder block, clamp a left side on the described driveshaft and driven seat surface and the right seat surface that drives, plug-in mounting fixator pins in the center hole of left side driving seat surface and right driving seat surface is so that pin slides arbitrarily in the whole waist shaped hole of driveshaft.
The utility model has solved the sense of rotation of variable displacement oblique tray type compressor no matter left-handed still dextrorotation can both proper functioning, guarantee the service behaviour and the working life of compressor, enlarged the using scope of variable compressor, satisfied the usage requirement of user different rotation directions.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a kind of structural representation of variable displacement oblique tray type compressor.
Fig. 2 is the driving block surface structure schematic representation of above-mentioned compressor.
Referring to Fig. 1 and Fig. 2, a kind of variable displacement oblique tray type compressor is equipped with cylinder block 1, at an end of cylinder block 1 protecgulum 2 is housed, and between cylinder block 1 and protecgulum 2 crankshaft cavity 3 is set, the other end at cylinder block 1 is equipped with valve board assembly 4, and control valve 5 and cylinder head 6 are linked into an integrated entity by screw 7 respectively.
The bearing 8,9 that is arranged in protecgulum 2 and cylinder block 1 is supporting live axle 10, and driveshaft 11, swash plate 12 and planetary plate 13 are installed on the live axle 10.Planetary plate 13 is connected with an end hinge of connecting rod 14, piston 15 pin joint in the other end of connecting rod 14 and the cylinder block 1.
Clamp left seat surface 16 and the right side driving seat surface 17 of driving on driveshaft 11, plug-in mounting fixator pins 18 in the center hole of left side driving seat surface 16 and right driving seat surface 17 is so that pin 18 slip arbitrarily in the whole waist shaped hole of driveshaft 11.
During use, motor car engine drives live axle 10 to right rotation by magnetic clutch 19, perhaps clockwise direction rotation, driveshaft 11 transfers torque to right the driving on the seat surface 17, make swash plate 12 and planetary plate 13 together or clockwise direction rotation to the right, the rotation of swash plate 12 causes planetary plate 13 swing, and the oscillating motion of planetary plate 13 makes piston 15 reciprocating in cylinder separately.When vaporizer heat load or compressor rotary speed change, control valve 5 passages in the cylinder head 6 are opened or are closed, make the variation in pressure in the crankshaft cavity 3, and then swash plate 12 angle respective change change the stroke of piston 15 and planetary plate 13, guarantee the regulatory function of variable displacement oblique tray type compressor thus, guaranteed the stable of automobile refrigerating amount.
When motor car engine drives live axle 10 to anticlockwise by magnetic clutch 19, when perhaps counterclockwise rotating, driveshaft 11 transfers torque to a left side and drives on the seat surface 16, swash plate 12 and planetary plate 13 are rotated left or counterclockwise together, the rotation of swash plate 12 causes planetary plate 13 swing, and the oscillating motion of planetary plate 13 makes piston 15 reciprocating in cylinder separately.
The utility model make into two drive seat surfaces after, need not recognize during use to, rotation can be used to the left or to the right, makes factory and the compressor user brings convenience to compressor.
