【発明の詳細な説明】 〔産業上の利用分野〕 本発明はヨーク部とシリンダ部からなる分割キャリパの
改良に関するものである。The present invention relates to an improved split caliper including a yoke portion and a cylinder portion.
自動車用ディスクブレーキの部品として従来のダクタイ
ル鋳鉄製のキャリパボディに代えてその重量軽減の目的
のためにキャリパボディのアルミニウム化が検討され、
一部量産化されている。For the purpose of reducing the weight of the conventional caliper body made of ductile cast iron as a component of a disc brake for automobiles, the use of aluminum for the caliper body is being considered,
Partly mass produced.
しかしアルミニウム合金で鋳造したキャリパは剛性が低
下し、特に高温時の強度が低下するため軽負荷のキャリ
パしか使用できないという問題がある。However, a caliper cast from an aluminum alloy has a problem that its rigidity is lowered and its strength is particularly lowered at a high temperature, so that only a lightly loaded caliper can be used.
またキャリパボディをヨーク部とシリンダ部とに分割構
成することも提案されているが、本発明はこの分割型キ
ヤリパボディの改良に係わるものである。Further, it has been proposed to divide the caliper body into a yoke portion and a cylinder portion, but the present invention relates to an improvement of this split type caliper body.

リパに存するものである。The gist of the present invention is, in a split caliper composed of a yoke portion and a cylinder portion, the yoke portion having a large strength requirement is formed of a fiber-reinforced composite material having high strength and is relatively lightweight, and the cylinder portion is lightweight and relatively inexpensive. The yoke portion and the cylinder portion are formed of aluminum or an aluminum alloy, and a member having good machinability such as iron or aluminum is formed in the joint portion of the yoke portion, or the yoke portion and the cylinder portion are formed by casting in a form in which the screw portion of the bolt is projected. The split caliper is characterized by being joined by screws.

ム等の単体ないしは合金が有効である。In the present invention, in a split caliper composed of a yoke portion and a cylinder portion, the yoke portion is formed of a fiber reinforced composite material having high strength and rigidity and relatively lightweight, and the cylinder portion (piston portion) is formed of aluminum or an aluminum alloy. However, long fibers or short fibers (including particles) of carbon, SiC, Al 2 O 3 , boron, ceramics, metal, etc. are effective as the reinforcing fibers of the above fiber-reinforced composite material, and the matrix thereof is A simple substance or an alloy of aluminum, titanium, magnesium, etc. is effective.
しかしながらこれらの繊維強化複合材は、比較的軽量で

ようにしてもよい。However, although these fiber-reinforced composite materials are relatively lightweight and have high strength, they have very poor machinability. Therefore, the yoke part and the cylinder part are connected by bolts, but the connecting screw part provided on the yoke part is made of iron,
Aluminum is cast, and the threaded portion is internally threaded to ensure the machinability and screw strength of the threaded portion. Further, it is desirable that the surface of the cast iron or aluminum member is uneven or knurled in order to enhance the bonding force with the composite material forming the yoke portion. Further, the bolt may be cast around the yoke with the threaded portion protruding.

により、この部分の切削性，ねじ強度を確保している。Example 1 (FIGS. 1 and 2) The yoke portion (a) is made of carbon, SiC, Al 2 O 3 , boron, ceramics, metal or other reinforcing fibers made of long fibers or short fibers such as aluminum, titanium, magnesium, etc. The cylinder part (b) is an aluminum alloy casting and both (a)
(B) is connected with a bolt (c). Further, the female thread portion (d) of the yoke portion (a) with which the male thread of the bolt (c) is screwed is a cast gurney member made of iron, aluminum or the like to secure the machinability and screw strength of this portion.
その際、雌ねじ部分（ｄ）とヨーク部（ａ）の繊維強化
複合材との結合力を上げるために鋳ぐるみ部材の表面に
は、凹凸ないしはローレット加工を施してある。At that time, in order to increase the bonding force between the female screw portion (d) and the fiber-reinforced composite material of the yoke portion (a), the surface of the cast-in member has been subjected to unevenness or knurling.
