Description
Technical Field
The utility model relates to an upper sucker component of an automobile air-conditioning compressor, belonging to the technical field of accessories of automobile air-conditioning compressors.
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 existing sucker component structure comprises a sucker, rubber packing, an inner ring, a hub, a rivet (A), an outer ring, a rivet (B) and a gasket; the sucker is connected with the outer ring to form a torque transmission part, 2 pressed pieces (the sucker and the outer ring) and 3 washers are riveted through rivets (B), and in actual operation, the sucker part is fixed on the main shaft through a nut for the hub and transmits torque through a spline.
The above structure has drawbacks in that: the torque transmission of the sucker component is transmitted by the rubber filler adhered between the inner ring and the outer ring, and the rubber, the inner ring and the outer ring are adhered together by glue and vulcanization, and the rubber bears torsional tensile stress; therefore, the method comprises the following steps: the connection strength is low, and the rubber is easy to tear off from the metal connection part, so that the failure is caused.
Disclosure of Invention
The utility model aims to provide a novel rubber suction cup component of an automobile air conditioner compressor, aiming at the defects of the structure of the suction cup component of the existing automobile air conditioner compressor.
The technical solution of the utility model is as follows: an improved design of a sucker component of an automobile air conditioner compressor comprises a sucker 1, a rubber pad rivet 2, a rubber gasket 3, a rivet 4, a hub 5 and a front plate 6; the rubber gasket 3 is nested on an assembly hole of the front plate 6, and the sucking disc 1 and the front plate 6 are combined together through the rivet 2 to form an elastic force transmission structure; the shock-absorbing rubber pad 7 is positioned between the sucker and the front plate and is used for absorbing impact force and noise generated when the sucker 1 rebounds in power failure; the hub 5 is fixed to the center of the front plate 6 by a rivet 4.
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 part is cancelled, the force transmission mode of the rubber part is changed, the original rubber force bearing mode is converted into the compression torsion force by the tension torsion force, the connection strength of rubber parts is improved, the service life of the rubber parts is prolonged, the types of the assembled parts are reduced, the installation process is simplified, and the part manufacturing cost is saved.
Description of the drawings:
FIG. 1 is a schematic structural diagram of a rubber suction cup component of an automobile air conditioner compressor.
Fig. 2 is an enlarged view of a structure in which a rubber bumper pad is mounted on a front plate.
FIG. 3 is a schematic view of the connection of the suction cup member and the compressor
In the attached figure 1: 1 is a sucker, 2 is a rubber washer rivet, 3 is a rubber buffer pad, 4 is a rivet, 5 is a hub, 6 is a front plate, and 7 is a shock-absorbing rubber pad.
The specific implementation mode is as follows:
the technical solution of the present invention is further illustrated by the following examples.
The structure of the sucker component on the automobile air conditioner compressor as shown in figure 1 comprises a sucker 1, a rubber pad rivet 2, a rubber gasket 3, a rivet 4, a hub 5 and a front plate 6; the rubber gasket 3 is nested on an assembly hole of the front plate 6, and the sucking disc 1 and the front plate 6 are combined together through the rivet 2 to form an elastic force transmission structure; the shock-absorbing rubber pad 7 is positioned between the sucker and the front plate and is used for absorbing impact force and noise generated when the sucker 1 rebounds in power failure; the hub 5 is fixed to the center of the front plate 6 by a rivet 4.
As shown in figure 2, the rubber cushion 3 is embedded in three holes of the front plate 6, the rubber cushion rivet 2 is inserted into the hole of the rubber cushion 6, and the periphery of the mounting hole of the front plate 6 is provided with a flange which surrounds the rubber cushion and is riveted and fixed with the sucker.
As shown in the attached figure 3, in actual use, the sucker component is fixed on the compressor main shaft through a nut, and a certain gap is formed between the sucker component and the left side surface of the compressor belt pulley; when the compressor needs to normally operate, the power of the engine transmits the torque to the belt pulley through the belt, the electromagnetic coil on the belt pulley generates electromagnetic suction to suck the sucker part of the sucker component and the belt pulley together, and the hub of the sucker component transmits the power to the main shaft of the compressor, so that the compressor normally operates.
When the electromagnetic coil of the compressor is electrified, electromagnetic suction force is generated to suck the sucker 1 to the left end face of the belt pulley, the sucker drives the rivet 2 to compress the rubber buffer cushion 3 during suction, the rubber buffer cushion 3 expands in the outer diameter direction after being compressed, and rubber fills the assembly gap between the rubber cushion and the outward flanging of the front plate 6 and bears a part of rotation torque firstly; at the moment, the sucker 1 is attached to the left end face of the belt pulley, and the sucker 1 and the belt pulley rotate synchronously. With the increase of the torque after the suction, the rubber buffer 6 is further deformed so that the front plate 6 is in direct contact with the rivet 2 to transmit the torque. The sucking disc 1 transmits the rotation torque to the rubber buffer pad 3 through the rivet 2, and then transmits to the front plate 6, and the front plate 6 transmits to the wheel hub 5 that the riveting is together through the rivet 4, and the rotation torque is transmitted to the compressor main shaft by wheel hub 5 at last, makes the compressor begin work. Otherwise; when compressor solenoid cuts off the power supply, because of the electromagnetic suction disappears, sucking disc 1 is pulled back original position by rubber buffer 3's elasticity, and rubber buffer pad is responsible for absorbing the impact force and the noise that produces when sucking disc kick-backs, and sucking disc 1 and belt pulley left end face break away from the contact, and the moment of torsion transmission route disconnection of compressor, compressor stop work.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
