Abstract
The utility model relates to the technical field of an automobile air-conditioning compressor, in particular to a main shaft driving rod for a piston type automobile air-conditioning compressor. The main shaft driving rod is characterized in that the length h of the main shaft driving rod is equal to 127.4mm; and the tail end of the main shaft driving rod is provided with two communicated ventilating holes. Compared with the prior art, the main shaft driving rod reduces the total length of parts thereof, and simultaneously can reduce the weight, and can effectively reduce the cost and power consumption of the compressor; and after the ventilating holes are added, the pressure in a cavity can enter a control valve smoothly, so that the pressure in the cavity can be better sensed by the control valve, and the angle of an inclined disc is controlled effectively.
Description
[technical field]
The utility model relates to the automobile air conditioner compressor technical field, specifically a kind of main shaft drives bar that is used for piston-type automobile air-conditioning compressor.
[background technique]
The main shaft drives bar is one of compressor major part.The main shaft drives bar is connected with the sucker wheel hub by spline, and when the sucker adhesive, the sucker running drives the running of main shaft drives bar, the main shaft drives bar is connected with swash plate, drives swash plate and does circumferential running, and swash plate drives the planetary plate running again, make reciprocating motion of the pistons, thereby make compressor operating.General main shaft drives bar all is solid, and cavity pressure enters control valve by main shaft bearing, and the main shaft drives bar is long, is not suitable for little capacity compressors.
[summary of the invention]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of main shaft drives bar that is used for piston-type automobile air-conditioning compressor is provided.
In order to achieve the above object, the utility model has designed a kind of main shaft drives bar that is used for piston-type automobile air-conditioning compressor, it is characterized in that: the length of main shaft drives bar is h=127.4mm, and the tail end of main shaft drives bar is provided with two vents that communicate.
The utility model is compared with prior art, and main shaft drives rod unit length overall reduces, and can reduce weight simultaneously, can effectively reduce cost and reduces the compressor power consumption; After increasing vent, cavity pressure can enter control valve smoothly, and being convenient to control valve can better the induction cavity internal pressure and effectively control the swash plate angle.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a sectional view of the present utility model.
Referring to Fig. 1 and Fig. 2,1 is vent.
[embodiment]
Now in conjunction with the accompanying drawings the utility model is described further.
Referring to Fig. 1 and Fig. 2, length h of the present utility model shortens to 127.4mm by 132.4mm, reduces 5mm, adds two vents that communicate 1 on main shaft drives bar tail end, and cavity pressure enters control valve by vent 1.The minimizing of the utility model length overall can bring alleviating of weight, can effectively reduce cost and reduces the compressor power consumption; Vent 1 on the utility model tail end can connect cylinder block and control valve simultaneously, and the endoceliac pressure of cylinder can enter control valve smoothly like this, and control valve can better be responded to the cylinder block cavity pressure and effectively control the swash plate angle.
