CALIPER FOR DISC BRAKES

摘要

A caliper comprises a hydraulic linking channel provided in a bridge section linking hydraulic cylinders, on an inner caliper section side, and hydraulic cylinders, on an outer caliper section side, to a cylinder-side hydraulic channel disposed on the back end of each respectively. A connecting channel forming section, which corresponds to each cylinder-side hydraulic channel and the hydraulic linking channel is provided, in advance, in a core used during casting of the inner caliper section, the outer caliper section, and the bridge section, and is formed by setting in a situation to be embedded at the same time as each caliper section and the bridge section are being integrally cast.

1. A caliper for disc brakes, comprising: an inner caliper section and an outer caliper section which are disposed by opposing to each other by sandwiching a disc rotor therebetween and both ends thereof in length directions are linked integrally via a bridge section; and pressurizing piston hydraulic cylinders which are provided to respective opposing surface regions of the inner caliper section and the outer caliper section and simultaneously pressurize the disc rotor from both surfaces thereof via brake pads when in an action, wherein:
the hydraulic cylinder on the inner caliper section side and the hydraulic cylinder on the outer caliper side are linked by cylinder-side hydraulic channels provided on respective back face sides and a hydraulic linking channel provided inside the bridge section; and each of the cylinder-side hydraulic channels and the hydraulic linking channel are set to be in a state embedded simultaneously in each of the caliper sections and the bridge section when integrally casting-molding each of the caliper sections and the bridge section through providing a connecting channel forming section corresponding to each of the cylinder-side hydraulic channels and the hydraulic linking channel in advance in a core used when casting-molding the inner caliper section, the outer caliper section, and the bridge section.
