Embodiment 1

[0024] Embodiment one, as figure 1 , figure 2 with image 3 As shown, the present invention provides a shock-absorbing and noise-reducing drive plate assembly for electromagnetic clutches, including a spline key 1 composed of a sleeve 1a and a flange 1b, and the compressor is connected by a spline in the sleeve 1a the main axis. The flange 1b is a triangular plate structure, an arc-shaped chamfer 1d is provided at each corner of the flange 1b, and a first installation is provided on the flange 1b close to each chamfer 1d. In the hole 1e, a support plate 1c is provided outside the center of each side of the flange 1b, and each support plate 1c is arranged on the side close to the sleeve 1a. The plate 1c is a rectangular plate, and the support plate 1c It has an integral structure with the flange plate 1b. A second mounting hole 1f is provided on the flange 1b adjacent to each supporting plate 1c. A first silencer plug 3 is installed in each first installation hole 1e, the...

Embodiment 2

[0031] Embodiment two, reed 4 described in embodiment one can also adopt following structure, as Figure 7 with Figure 8 As shown, the annular spring plate 4a adopts a straight plate 4m structure, and a sound damping plate 4d is provided on one side of the straight plate 4m.

[0032] The basic principle of shock absorption and noise reduction of the present invention: the electromagnet is energized to generate a magnetic field, the suction cup 2 is attracted to the pulley, and as the suction cup 2 moves, the reed 4 riveted with it also moves accordingly, and the second silencer plug 5 and the reed 4 synchronous movement, and after the second silencing plug 5 moves, it will quickly contact with the support plate 1c, squeeze the second silencing plug 5 to deform, under the obstruction of the support plate 1c, the second silencing plug 5 is compressed by force, effectively hindering The movement of the reed 4 hinders the suction speed of the suction cup 2, thereby effectively r...

Abstract

The invention relates to a damping and noise-reduction drive plate assembly for an electromagnetic clutch. The damping and noise-reduction drive plate assembly for the electromagnetic clutch comprises a spline plate (1) consisting of a sleeve (1a) and a flange (1b), wherein the spline plate is connected with a suction cup (2) through a group of springs; the flange is connected with a group of first noise-reduction plugs (3); the first noise-reduction plugs are in noise-reduction matching with the suction cup correspondingly; a noise-reduction plate (4d) is arranged on each spring; each noise-reduction plate is connected with a second noise-reduction plug (5); and the second noise-reduction plugs are in noise-reduction matching with the flange correspondingly. The damping and noise-reduction drive plate assembly for the electromagnetic clutch has the advantages that by the damping and noise-reduction drive plate assembly, the suction speed of the suction cup can be reduced effectively, then rigid impact, suction sound and contact abrasion are reduced when the suction cup sucks a belt pulley, so that the effect of reducing vibration and noises is achieved, the service life of the electromagnetic clutch can be prolonged, meanwhile, the structure of a drive plate is improved on the premise of meeting performance, and shortcomings of large resistance to axial deformation of complete-cycle rubber drive plates and three-eye rubber drive plates are avoided effectively.

Description

technical field [0001] The invention relates to an automobile air-conditioning clutch, in particular to a shock-absorbing and noise-reducing driving disk assembly for an electromagnetic clutch. Background technique [0002] The NVH characteristics of automobiles, that is, noise, vibration and harshness, are one of the comprehensive issues concerned by the automobile industry and related auto parts industries. According to statistics, about 33% of automobile failures are related to NVH problems of automobiles, and nearly 20% of the research and development expenses of major automobile companies in the world are invested in solving NVH problems of automobiles. [0003] From the current automobile quality situation, the noise problem of electromagnetic clutch of automobile air conditioner is very common, and the noise problem generated by electromagnetic clutch when automobile air conditioner is running has attracted more and more attention and attention from enterprises and us...
