Problems solved by technology
However, during the differential rotation of the fan fixed plate relative to the magnet fixed plate, the high-temperature heat generated cannot be discharged to the outside in time, and the heat is directly transmitted to the transmission bearings in the electromagnetic clutch, so that the inner cavity of the transmission bearing with the end face seal is placed Some lubricating grease is diluted by high-temperature heat and overflows, causing premature wear and damage of transmission bearings from time to time, which significantly increases the user's use and maintenance costs

Embodiment Construction
[0058] Such as Figure 1 to Figure 5 As shown, this electromagnetic clutch magnet fixed disk with cyclone cooling fins mainly includes a disk body made of aluminum alloy and a bearing hole connected thereon; In the fixing holes evenly spaced, 18 permanent magnets 3 are inlaid and connected to the iron plate 4 fixedly connected to the aluminum alloy disc body, and the iron plate 4 is firmly attracted and connected ( Figure 1-Figure 2Shown); On the inner circumference of the front end face between the bearing hole and the permanent magnet 3, the disc body is provided with some upright cyclone cooling fins 1 at intervals; the height of the cyclone cooling fins is 15 millimeters; On the end surface of the disc body between the cooling fins 1, there are cooling ventilation holes 2. In order to increase the effect of ventilation, heat dissipation and cooling, on the outer periphery of the front end surface between the permanent magnets, the disc body is connected with raised heat ...

The invention discloses an electromagnetic clutch magnet fixed disc with cyclone radiating fins, wherein a plurality of permanent magnets (3) which are embedded at intervals are arranged on the periphery of the front end of the disc body; a plurality of cyclone radiating fins (1) are arranged at intervals on the inner periphery of the front end surface between bearing holes and the permanent magnets on the disc body; and a plurality of radiating air vents (2) are arranged on the end surface of the disc body between the plurality of cyclone radiating fins. During work, cyclone generated by the rotation of cyclone radiating fins enters the space of the disc body relative to an actuation disc through the radiating air vents, and high temperature heat transferred to each transmission bearing is discharged smoothly outwards through the gap between the electromagnetic clutch and other connection components to achieve recirculation with the external cooling air and realize ventilation and temperature reduction of the transmission bearings, thereby the service life of the transmission bearings is effectively prolonged, and the use and maintenance costs of the user is reduced obviously.
Description
technical field [0001] The invention relates to engineering components, devices and methods for vehicles, in particular to an electromagnetic clutch magnet fixed disk, a manufacturing method and an electromagnetic clutch of the disk. Background technique [0002] Electromagnetic clutch components in the prior art, such as the magnet fixed disk of the automobile electromagnetic clutch, are placed in the inner cavity of the fan fixed disk of the automobile electromagnetic clutch, and are rotatably connected with the transmission shaft through the transmission bearing. When working, when the water temperature of the automobile engine reaches the set value, the electromagnet core coil of the electromagnetic clutch is energized and connected with the suction plate, and at the same time drives the magnet fixed plate fixedly connected with the suction plate to rotate, and passes through the magnet fixed plate. The magnet and the end face of the inner cavity of the fan fixing plate ...
