ッチ被動板の製造法も知られている。(Prior art) Conventionally, the manufacturing method of automobile clutch driven plates uses long fibers such as asbestos and glass fibers as a fiber base material, and adds thermosetting resin, comb material, other friction modifiers, etc. to the fiber base material. The woven clutch driven plate was formed by impregnating the material with a material, preforming it by winding it into an annular shape, then hot-pressing it, molding it, and finishing it by after-curing, gouging, and polishing. On the other hand, as disclosed in JP-A-61-41022 and JP-A-61-70225,
A clutch in which a resin-molded clutch facing plate made of woven asbestos cloth, thermosetting plum oil, and a friction modifier is placed on a backing material made of light alloys such as aluminum, duralumin, and magnesium, and then integrally formed under heat and pressure. Methods of manufacturing driven plates are also known.

て強度が補強されていて破壊回転数が高い。Compared to the manufacturing method of woven clutch driven plates, this clutch driven plate manufacturing method saves time and processing costs because it does not require the process of impregnating the fiber base material with a binder or friction modifier, or the process of wrapping it into a tablet and preforming it. can. Furthermore, this clutch driven plate generally has stable quality, is reinforced in strength by a backup material, and has a high breaking rotation speed.

った。(Problem to be Solved by the Invention) However, the clutch driven plate manufactured by the above manufacturing method is heavier than the woven clutch driven plate.
In order to use this for clutch discs, it was necessary to increase the strength of the transmission synchronizer.
それを改善するため、円筒突起のある金型を用いて熱圧
成形時に複数個のディンプルを形成し、クラッチ被動板
を軽くする方法が考えられた。In order to improve this, a method was devised in which a mold with cylindrical protrusions was used to form multiple dimples during hot press molding to make the clutch driven plate lighter.
しかし、熱圧成形と同時にディンプルを形成しようとす

、熱圧成形抜脱形する際フェーシング部材が割れたりす
る場合もあった。However, if you try to form dimples at the same time as hot-press molding, the clutch facing member is made of a material with poor flowability, so the clutch facing member remains in the dimple area between the cylindrical protrusion and the backup material, making it impossible to achieve a lightweight effect. Moreover, there was the disadvantage that the clutch driven plate had low density and was brittle. In addition, due to its brittleness, the facing member sometimes cracks during hot press molding and removal.

It is a back-up material such as aluminum, duralumin, magnesium, etc., preferably formed into a ring-shaped plate of a light metal with a specific gravity of 5 or less, and the surface that becomes the joint surface with the clutch facing member is made of epoxy or phenol-based material. The surface is roughened by shot blasting, bath polishing, chemical etching, etc. because it is coated with a nitrile phenol adhesive or the like.

A binder commonly used in friction materials such as resin and rubber materials such as NB and 8BB, cashew dust,
Friction modifiers commonly used in friction materials, such as friction dust, graphite, barium sulfate, clay, calcium carbonate, aluminum powder, copper powder, and zinc powder, can be blended.

It is molded under conditions in the range of 0 kg/cd using a mold as shown in FIG. 2 having a plurality of cylindrical protrusions with rounded tips as shown in FIG.

できる。(Function) In the present invention, when performing thermoforming, dimples are formed on the surface of the clutch facing member by a plurality of cylindrical protrusions with rounded tips, so that the clutch facing member at the dimple portion backs up with the cylindrical protrusions. It is easy to flow out of the dimple from between the material and the material, which prevents the density of the clutch facing member from decreasing after molding.
It is also possible to prevent the clutch facing member from cracking during demolding.

とができる。Further, when a tapered cylindrical projection is used, the density of the cylindrical projection side facing member increases as the cylindrical projection is pushed in. Furthermore, during demolding, the shearing force generated between the clutch facing member on the side surface of the cylindrical protrusion and the cylindrical protrusion can be reduced, thereby preventing the clutch facing member from cracking.
