のボルト接合時のネジ強度が劣るという問題が生ずる。In order to reduce the weight of the split caliper, the caliper member is cast from a light metal such as aluminum or an aluminum alloy, but in that case, there arises a problem that the screw strength of the yoke portion and the piston portion at the time of bolt joining becomes poor.
本発明はこの問題に対処した分割形キャリパの補強を提
供しようとするものである。The present invention seeks to provide split caliper reinforcement that addresses this problem.

である。A gist of the present invention is a split type caliper in which a yoke portion and a piston portion are divided, and both portions are bolt-bonded to each other, and the yoke portion is an integrally formed reinforcing member formed by pressing and bending a steel plate. The split caliper is characterized by the fact that the yoke part and the piston part are bolted to each other through a screw hole that penetrates this reinforcing material, and it is intended to meet the intended purpose. It is a thing.

果が得られる。As described above, according to the present invention, in the split type caliper including the yoke portion and the piston portion, the yoke portion is formed by pressing and bending a steel plate having high strength and Young's modulus, and integrally forming a reinforcing material with light metal. The yoke portion and the piston portion are joined together through the above-mentioned reinforcing material when they are joined by bolts. This makes it possible to improve the screw strength at the time of joining the bolts, and the rigidity of the caliper,
It has advantages such as high temperature strength and weight reduction, and the fact that the reinforcing material can be press-molded, which is effective in terms of mass productivity and cost. Furthermore, since the reinforcing material is integrally molded, positioning during casting can be performed. Various excellent effects such as easyness can be obtained.

当てられる。The reinforcing material (c) is made by pressing and bending a steel plate having high strength and Young's modulus, but in the example shown in the figure, one steel plate is pressed and bent into a multi-step comb tooth shape, and both side projections are formed. (1) and (2) and the intermediate connecting portion (3) are applied to the screw hole processed portion.

リパを得る。Therefore, the reinforcing material (c) is applied from the split joint surface side of the yoke portion (a).
A screw hole is formed through each of the parts (1), (2) and (3), and a screw hole corresponding to the above-mentioned screw hole of the yoke part (a) is also formed on the piston part (b) from each step part (5). By machining and screwing the bolt (6) into each screw hole so that the head of the bolt (6) is locked to the step (5), the yoke (a) and the piston (b) are brought into contact with each other on the surface (4). Obtain a split caliper bolted to.
