Abstract
The utility model relates to an oblique disc rotation type compressor with variable discharge capacity. The utility model comprise an air cylinder body, a front shell body, a back shell body part, a driving shaft, an oblique disc, a guide pin of a ball head and a guide hole, wherein, a piston is arranged in the air cylinder body, the front shell body and the air cylinder body form a crank cavity, and the driving shaft is supported by the air cylinder body and the front shell body. A driving disc is fixed on the driving shaft. The oblique disc is arranged on the driving shaft and is connected with the piston through a pair of slide shoes. The guide pin of a ball head is fixedly arranged on the driving disc. The guide hole is formed on the oblique disc, and the shape of the guide hole forms a curve shape or a straight line shape. When the structure is used, the processing of the guide pin of a ball head and the guide hole is easy, and the precision can be guaranteed. Thus, the manufacturing cost of the compressor is reduced.
Description
The utility model relates to a kind of variable displacement swash plate rotary compressor that is used for Vehicular air-conditioning apparatus.
The vital part bulb guide finger that passes to the swash plate torque as drive plate of the variable displacement swash plate rotary compressor of existing air conditioner for motor vehicle normally is fixedly installed on the swash plate, and the bulb pilot hole is to form on drive plate, the shortcoming of such torque-transmitting mechanisms is the processing technology complexity and is difficult to guarantee machining accuracy, thereby passing rate of processing is low, causes the processing cost height.
Therefore, the purpose of this utility model provides a kind of variable displacement swash plate rotary compressor that is used for air conditioner for motor vehicle, and the torque-transmitting mechanisms processing between its drive plate and swash plate is easy and can guarantee machining accuracy.
For achieving the above object, variable displacement swash plate rotary compressor of the present utility model comprises: cylinder block, axially be arranged side by side several cylinder-bore, and in described each cylinder-bore, piston is installed; Front case, it seals the front end of described cylinder block, the inner crank chamber that forms of described cylinder block; Rear case parts, rear case have the rear end of air aspiration cavity and exhaust cavity and closed cylinder body and control valve parts are housed; Live axle and drive plate parts, described live axle are by described cylinder block and front case supporting, and it has an axis and axially passes described crank chamber also can be around this axis rotation, and described drive plate is fixed on the described live axle; Described swash plate is installed on the live axle by its center hole, and described piston is connected with swash plate by crawler shoe; And be arranged on torque-transmitting mechanisms between described drive plate and swash plate, comprise a bulb guide finger and a pilot hole; Be characterized in: described bulb guide finger is fixedly installed on the described drive plate, and described pilot hole forms on described swash plate.
Described pilot hole be shaped as curvilinerar figure or lineal shape.
Adopt technique scheme of the present utility model, because the bulb guide finger is arranged on the drive plate and pilot hole is to process on swash plate, such structure can improve the machining accuracy of bulb guide finger and pilot hole, has also reduced the manufacture cost of variable displacement swash plate rotary compressor simultaneously.
Understand the purpose of this utility model, characteristics and advantage for clearer, a preferred embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.
Fig. 1 is the longitudinal section of the variable displacement swash plate rotary compressor of a preferred embodiment of the present utility model;
Fig. 2 is the structure longitudinal section of live axle, drive plate and swash plate parts of the variable displacement swash plate rotary compressor of a preferred embodiment of the present utility model;
Fig. 3 is the front end view of Fig. 2.
For the purpose of the convenience of explanation, all same or analogous component all adopt same label in the above-mentioned accompanying drawing.As shown in the figure, variable displacement swash plate rotary compressor of the present utility model comprises: cylinder block 8, axially be arranged side by side several cylinder-bore 11, and in each cylinder-bore 11, piston 13 is installed; Front case 7, the front end of its closed cylinder body 8, the inner crank chamber 14 that forms of cylinder block; Rear case parts 10, rear case 10 ' have the rear end of air aspiration cavity 15 and exhaust cavity 16 and closed cylinder body 8 and control valve parts 18 are housed; Live axle and drive plate parts 1, live axle 5 are by cylinder block 8 and front case 7 supportings, and it has an axis 19 and axially passes crank chamber 14 also can be around these axis 19 rotations, and drive plate 1 ' is fixed on the described live axle 5; Swash plate 4 is installed on the live axle 5 by its center hole 6, and piston 13 is connected with swash plate 4 by crawler shoe 12; And the torque-transmitting mechanisms that is arranged on 4 of drive plate 1 ' and swash plates, comprise a bulb guide finger 2 and pilot hole 3.The shape of pilot hole 3 can be curvilinerar figure or lineal shape.Bulb guide finger 2 is fixedly installed on the described drive plate 1 ', and pilot hole 3 is to be processed on swash plate 4.
As mentioned above, bulb guide finger 2 is installed on the drive plate 1 ' of the present utility model, on swash plate 4, offers curve or rectilinear pilot hole 3; Wobbler 4 is installed on the live axle 5 by its center hole 6, and is connected with the drive plate with bulb guide finger 2 by pilot hole 3, so the inclination angle of swash plate can change; Piston 13 is installed in the cylinder-bore 11 of cylinder block 8, is connected with swash plate 4 by crawler shoe 12, is fixed on drive plate 1 ' on the live axle 5 in the crank chamber 14 and drives just that swash plate 4 rotatablely moves so that piston 13 is periodically done straight reciprocating motion in cylinder-bore 11.Because the machining accuracy of bulb guide finger and pilot hole obtains to guarantee, so the displacement that wobbler 2 can accurately be controlled self by pilot hole 3 along moving of bulb guide finger 4 is moved.
