Embodiment 2

[0074] Example 2 as Figure 6 shown in Figure 3 to Figure 5 In the case of the other structures of the transmission disc embodiment 1 shown as being similar, a keyway is provided in the shaft sleeve 106 on the transmission disc through hole 101, and an interference fit is formed by pressing the shaft sleeve 106 into the hole in the center of the transmission disc. 108 annular welds at the junction. Through this structure, the processing technology of the through hole of the transmission disc can be simplified, and two parallel processes of processing the shaft sleeve and the processing of the transmission disc can be formed, thereby improving the production efficiency.

Embodiment 3

[0075] Example 3 as Figure 7 As shown, in the case of other structures similar to those of Embodiment 2, the bushing 106 is omitted, and a keyway is provided on the hole wall at the center of the transmission disc to form a through hole 101a of the transmission disc. On the premise of satisfying the performance of the transmission disc, this structure can further reduce the production cost and reduce the weight of the transmission disc.

Embodiment 4

[0076] Example 4 as Figure 8 As shown, in the case of Embodiment 2 with other similar structures, an inner wall 107 surrounding the through hole of the transmission disc is provided in the transmission disc cavity. Two accommodating cavities are formed with the outer wall 107a, so that the transmission plate can adapt to the installation of different electromagnetic cores and electromagnetic coils according to the structure of the electromagnetic clutch.

Abstract

The invention discloses a drive disc of an electromagnetic fan clutch. A drive disc body is provided with air magnetic isolation through holes and connecting ribs as well as concentrating flux layers. The air magnetic isolation through holes and the concentrating flux layers are arranged alternately along the radial direction of the drive disc body. The concentrating flux layers are provided with friction increasing grooves. The air magnetic isolation through holes and the connecting ribs are smaller in thickness than the concentrating flux layers. Six connecting ribs are uniformly arranged among the concentrating flux layers, and the connecting ribs on the both sides of the concentrating flux layers are arranged at an interval angle of 30 degrees along the radial direction of the drive disc body. The drive disc body is provided with drive disc through holes, and the concentrating flux layers are provided with receiving walls. The drive disc is made of an SPHE (Steel Plate Heat Elongation) steel plate or an SPHD (Steel Plate Heat Draw) steel plate. According to the invention, magnetic isolation effect of a solid magnetic isolation layer is realized by the air magnetic isolation through holes, meanwhile, the weight of the disc body is reduced, transmission efficiency is improved and the arrangement of the connecting ribs and the grooves on the end surfaces of the concentrating flux layers not only meets rigidity of the disc body but ensures friction effect of the end surfaces of the concentrating flux layers as friction surfaces. The invention also discloses a method for manufacturing the drive disc of the electromagnetic fan clutch.

Description

technical field [0001] The invention relates to a metal part processing method, a mold and a part manufactured by using the same, in particular to a method for manufacturing an automobile electromagnetic fan clutch transmission disc, a mold and a transmission disc manufactured by the method. Background technique [0002] Manufacturing the transmission disk of the automobile electromagnetic fan clutch needs to process a magnetic isolation layer on the end surface of the transmission disk, so that several magnetic conduction areas are formed on the end surface, so as to meet the requirements of the electromagnetic core in the transmission disk cavity and the electromagnetic coil wound on the electromagnetic core. The distribution method realizes the need to generate electromagnetic attraction in different areas of the end face of the transmission disc, and the electromagnetic attraction in different areas attracts different suction discs, driving the components connected with t...
