Problems solved by technology

The driven plate with this structure has high cost, complex process, difficult production conditions, and if the riveting is not good, it is easy to cause the friction plate to fall off and cause a safety accident.
In addition, due to the difficulty of controlling the riveting force of the riveted clutch, the flatness of the friction plate itself, the hole position and other problems, it is impossible to achieve an integrated flatness between the friction layer and the metal disc no matter how riveted.
Moreover, the riveted driven disc needs to punch holes on the surface of the friction plate, and the surface of the friction surface cannot be fully utilized

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] refer to figure 1 , figure 2 , image 3 , a clutch driven disc, comprising a metal disc 1 and a friction layer 2, the friction layer 2 is heat-pressed on the metal disc 1 to form an integral body with the metal disc 1.

[0026] The metal disk includes a central ring 3 and several identical sector-shaped disk bodies 4 connected to the central ring 3 . The sector-shaped disks 4 are provided with thermosetting holes 5, and the distribution of the thermosetting holes on each sector-shaped disk is the same. In this embodiment, the heat-setting holes 5 are divided into several rows arranged from the inside to the outside, each row of heat-setting holes 5 is arranged in an arc shape, and the arc shape of the heat-setting holes has the same shape as that of the metal plate. center of circle.

Abstract

The invention discloses a clutch driven disk, which comprises a metal disk and a friction layer, wherein the friction layer is hot-pressed on the metal disk and is integrated with the metal disk. A manufacturing method of the clutch driven disk comprises the following steps of: A, pressing a friction material into a friction layer cold blank, and stamping a metal plate into a metal disk; B, preparing a hot-pressing single die, and hot-pressing the hot-pressing single die; C, cooling a semifinished clutch driven disk product pressed in the step B, pressing a pressure block at the normal temperature for standing for 10-12 hours, and conveying to a drying oven for performing secondary sulfurization; and D, performing surface finishing on the surface of the product through a grinding machine. The driven disk is easy and convenient to manufacture, the friction layer on the hot-pressed clutch driven disk is prevented from falling off, high flatness is realized, and the bonding surface of the driven disk is larger; and due to the adoption of the pressed clutch driven disk, a flywheel and a pressure plate can be completely prevented from being damaged by complete grinding of the effective surface of the friction layer.

Description

(1) Technical field [0001] The invention relates to a clutch driven disc and a manufacturing method of the clutch driven disc. (2) Background technology [0002] The clutch driven disc includes a metal disc and a friction layer attached to the metal disc. The current clutch driven disc generally connects the friction layer to the metal disc by means of rivets. The cost of the driven plate with this structure is high, the process is complicated, the production conditions are difficult to grasp, and if the riveting is not good, it is easy to cause the friction plate to fall off and cause a safety accident. In addition, due to the difficulty of controlling the strength of the riveting clutch, the flatness of the friction plate itself, the hole position and other problems, it is impossible to achieve an integrated flatness between the friction layer and the metal disc no matter how riveted it is. Moreover, the riveted driven disc needs to be drilled on the surface of the frict...
