Description

Automobile air-conditioning compressor integrated swash plate

technical field

The invention belongs to the technical field of automobile air-conditioning compressors, in particular to an integrated swash plate of an automobile air-conditioning compressor.

Background technique

In the refrigeration system of the automobile air conditioner, the displacement of the swash plate compressor generally changes according to the change of the inclination angle of the swash plate on the main shaft. Usually, when the compressor is at low speed or high load, the swash plate is at the maximum angle state, that is, when the piston runs to the maximum stroke; conversely, when the compressor is at high speed or low load, the swash plate is at the minimum angle state , that is, the minimum travel time of the piston.

Therefore, the swash plate is the main component of the swash plate compressor. However, the swash plate of the traditional automotive air-conditioning compressor is a split structure, which has disadvantages such as inconvenient installation, poor reliability, difficult positioning, and low transmission efficiency.

Contents of the invention

In view of this, the object of the present invention is to provide an integrated swash plate for an automobile air-conditioning compressor, whose inclination angle is constant, and the displacement change is regulated by external pressure, and has the advantages of simple structure, convenient installation, accurate positioning, good safety and reliability and The utility model has the characteristics of strong practicability, and effectively solves the problems existing in the swash plate of the automobile air-conditioning compressor in the prior art.

To achieve the above object, the present invention provides the following technical solutions:

An integrated swash plate for an automobile air-conditioning compressor, comprising a swash plate body, the swash plate body is provided with a central hole for sliding fit on the main shaft of the compressor with a single degree of freedom, and the axis of the central hole is in line with the swash plate body. The axes of the disc body intersect and have an included angle.

Further, the inner wall of the central hole is provided with a slide groove for sliding engagement with the main shaft in a single degree of freedom.

Further, at least two chutes are uniformly distributed in a ring.

Further, two chutes are uniformly distributed in a ring.

Further, the chute is a trapezoidal chute.

Further, the axis of the central hole and the axis of the swash plate body are both located on the symmetrical plane of the sliding groove.

The beneficial effects of the present invention are:

The integrated swash plate of the automobile air-conditioning compressor of the present invention is provided with a single-degree-of-freedom sliding fit between the central hole and the main shaft of the compressor, and the axis of the central hole is set to intersect the axis of the swash plate body, so that the swash plate body can be relatively The main shaft of the compressor is set at an inclination, and the inclination angle remains unchanged, and the displacement change is regulated by external pressure; it adopts an integrated structure, which has the characteristics of simple structure, convenient installation, accurate positioning, good safety and reliability, and strong practicability. The problems existing in the swash plate of the automobile air-conditioning compressor in the prior art are solved.

Description of drawings

In order to make the purpose, technical scheme and beneficial effect of the present invention clearer, the present invention provides the following drawings for illustration:

Fig. 1 is the structural representation of the embodiment of the integrated swash plate of the automobile air-conditioning compressor of the present invention;

Fig. 2 is a cross-sectional view of the integrated swash plate of the automobile air-conditioning compressor in this embodiment.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

As shown in FIG. 1 , it is a structural diagram of an embodiment of an integrated swash plate for an automobile air-conditioning compressor according to the present invention. An integrated swash plate for an automobile air-conditioning compressor in this embodiment includes a swash plate body 5, on which a central hole 1 for single-degree-of-freedom sliding fit and fitting on the main shaft of the compressor is provided, and the axis of the central hole 1 It intersects with the axis of the swash plate body 5 and has an included angle.

Further, the inner wall of the central hole 1 is provided with a chute for sliding engagement with the main shaft in a single degree of freedom, and there may be only one chute, of course, at least two chutes may be evenly distributed in a ring. Specifically, the chute of this embodiment is uniformly arranged in two rings, which are respectively chute 2 and chute 3, and the symmetrical planes of chute 2 and chute 3 are coplanar, and the axis of central hole 1 of this embodiment and the axes of the swash plate body 5 are located on the symmetrical plane of the chute 2 or the chute 3, and the chute in this embodiment is a trapezoidal chute. By setting the key connection between the chute and the main shaft of the compressor, it has the advantages of simple structure, convenient assembly and disassembly, good mechanical properties and high safety and reliability.

The integrated swash plate of the automobile air-conditioning compressor of this embodiment is provided with a single-degree-of-freedom sliding fit between the central hole and the main shaft of the compressor, and the axis of the central hole is set to intersect the axis of the swash plate body, so that the swash plate body can be relatively Since the main shaft of the compressor is inclined, and the inclination angle remains unchanged, the displacement change is regulated by external pressure; it adopts an integrated structure, which has the characteristics of simple structure, convenient installation, accurate positioning, good safety and reliability, and strong practicability. The problem existing in the swash plate of the automobile air-conditioning compressor in the prior art is solved.

The above-mentioned embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention. The protection scope of the present invention shall be determined by the claims.
