Description

Sucking disc part on automobile air conditioner compressor

Technical Field

The utility model relates to a last sucking disc part of vehicle air conditioner compressor belongs to vehicle air conditioner compressor annex technical field.

Background

The suction cup component is one of the important components of the variable displacement compressor of the automobile air conditioner, the driving force of the compressor is from an automobile engine, and the suction cup component is used as a torque transmission component of the compressor and used for transmitting the power by connecting a compressor belt pulley and a compressor main shaft together. When the automobile normally runs, the engine transmits the rotating torque to the belt pulley through the belt, when the air conditioning system stops working, the sucking disc cannot rotate along with the belt pulley due to a certain gap between the sucking disc and the belt pulley, the power of the automobile engine cannot be transmitted to the compressor, and the compressor is in a non-working state; when the air conditioning system needs to work, the control system enables the electromagnetic coil inside the belt pulley to generate a magnetic field through current, the electromagnetic force attracts the sucker component to the belt pulley, the belt pulley drives the sucker to rotate together, and the sucker transmits rotating torque to the compressor spindle, so that the automobile air conditioning compressor starts to work.

The structure of the existing sucker component is shown in figure 4, and comprises a sucker 1, a rubber filler 2, an inner ring 3, a hub 4, an A rivet 5, an outer ring 6, a B rivet 7 and a gasket 8; the connection part of the sucker 1 and the outer ring 3 is provided with a torque transmission part, the sucker 1 and the outer ring 6 are riveted by two pressed pieces and 3 washers 8 through B rivets 7, and during actual operation, the sucker part is fixed on a main shaft through a nut for a hub and transmits torque through a spline. In the in-service use process, the moment of torsion transmission of sucking disc part relies on the rubber packing that bonds between inner ring circle and outer ring circle to transmit, because rubber packing and inside and outside adopt glue and vulcanizer to bond together between the ring circle, joint strength is lower, when receiving great torsional tensile stress, makes easily to tear between rubber packing and the metal connection's the position and takes off, leads to sucking disc part to damage, and the transmission effect is inefficacy, seriously influences the normal work of compressor.

Disclosure of Invention

The utility model aims to provide a novel last sucking disc part of vehicle air conditioner compressor to the above-mentioned defect that current vehicle air conditioner compressor sucking disc part structure exists.

The technical solution of the utility model is as follows: a rubber suction cup component of an automobile air conditioner compressor structurally comprises a suction cup, a rubber gasket rivet, a rubber gasket, a rivet, a hub and a front plate; wherein the surface of the front plate is provided with 3 assembling holes at equal intervals around the center, each assembling hole is provided with 1 rubber gasket, and 3 rubber gasket rivets respectively penetrate through the corresponding rubber gasket and fix the front plate and the sucker in a riveting way; the upper edge and the lower edge of the rubber gasket extend outwards, so that the front plate is tightly embedded into the side surface of the rubber gasket to form an embedded part; the hub is mounted at the center of the front plate through a rivet.

The utility model has the advantages that: the whole rubber bonding structure between the sucking disc and the hub in the traditional rubber sucking disc component is eliminated, the force transmission mode of the rubber part is changed, the tensile torsional force is converted into the compressive torsional force, the connection strength and the service life of the part are improved, the types of the assembled parts are reduced, the installation process is simplified, and meanwhile, the manufacturing cost of the part is saved.

Detailed Description

The technical scheme of the utility model is further explained in the following with the attached drawings. Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial" and the like indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for convenience of description of the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific direction to be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly, e.g., as meaning a fixed connection, a removable connection, or an integral part; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

As shown in fig. 1 and 2, the upper sucker component of the automobile air conditioner compressor structurally comprises a sucker 1, a rubber gasket rivet 2, a rubber gasket 3, a rivet 4, a hub 5 and a front plate 6; wherein the front plate 6 is arranged on the surface of the sucker 1 through a rubber gasket rivet 2 to form an elastic force transmission structure; the hub 5 is arranged at the central part of the front plate 6 through a rivet 4 to form a torque output structure; the rubber gasket 3 is arranged outside the rubber gasket rivet 2, the side face of the rubber gasket 3 and the edge of the front plate 6 form an embedding part 7, and the sucker 1, the front plate 6 and the rubber gasket 3 are combined together through the rubber gasket rivet 2 to form a torque input structure.
