本発明は複合材利用のキヤリパに関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a caliper using a composite material.

In order to reduce the weight of the conventional ductile cast iron brake body as a component for automobile disc brakes, the use of aluminum for the rear brake body is being considered and some parts are being mass-produced. However, a caliper cast from an aluminum alloy has a problem in that it can only be used for light-load calipers because its rigidity and strength especially at high temperatures are reduced.

の目的を収めたものである。 In order to deal with such problems, the present inventor molded the cylinder part in advance with a base material made of A or Mg, and then molded the entire caliper by casting this with a composite material containing the base material. This achieved the intended purpose.

とする複合材利用キヤリパに係わるものである。[Means and effects for solving the problem] The gist of the present invention is to mold the cylinder part of the caliper in advance with a base material made of A or Mg, and strengthen the remaining part by casting these parts. This invention relates to a caliper using a composite material, characterized in that it is integrally molded with a composite material made of fibers and the above-mentioned base material.

合金材キヤリパと複合材キヤリパの長所を兼ね備
えたキヤリパが得られる。 In the present invention, the part that is pre-molded with a base material made of A or Mg is the cylinder part of the caliper,
By encasing this and molding other parts with a composite material made of the base material and reinforcing fibers, a caliper that combines the advantages of a light alloy caliper and a composite caliper can be obtained.
即ち、強化繊維（例えばカーボン繊維、セラミ
ツクス繊維）と、Ａ又はMgからなる母材との
複合材は、切削化工性が悪いため加工刃物の寿命

分を上記複合材で構成すれば、複合材利用キヤリ
パの強度向上という利点と、切削箇所の切削性向
上という利点の両者に優れたものとなる。 That is, a composite material of reinforcing fibers (for example, carbon fibers, ceramic fibers) and a base material made of A or Mg has poor machinability and shortens the life of the cutting tool. Therefore, in the present invention, instead of forming the entire caliper with a composite material, the cylinder part, which has many cutting parts in the caliper, is formed not with a composite material but with its base material A or Mg, and the other parts are made of the above composite material. If this is done, the caliper using the composite material will have an excellent advantage of both improved strength and improved machinability at the cutting location.
このような複合材としてはカーボン、セラミツ
クスの強化繊維等とＡ、Mg等の軽合金材とか
らなるものが用いられる。 As such a composite material, a material made of reinforcing fibers such as carbon or ceramics and a light alloy material such as A or Mg is used.

Next, set each of the above pre-molded parts (a), (b), and (c) in the mold for molding the caliper, fill the remaining parts with carbon fiber, and place each of the above parts in the mold. The same molten aluminum alloy that was molded was uniformly injected, and the remaining parts were molded with a composite material (A) made of carbon fiber and aluminum alloy.At the same time, each part (a) and (b) previously molded with aluminum alloy was molded. , (c) is cast, and the desired integrally molded caliper is obtained.
