Abstract
A method for manufacturing a monoblock brake caliper in which brake hydraulic lines, which are pipes, are provided inside a caliper body and a brake hose fixing device is provided on the outside the caliper body, and a plurality of cylinders are cast by sand casting. Prior to the casting process for forming the caliper body, the brake hydraulic lines are pressed into a sand cast, and then the caliper body is formed by the casting process. The brake hose fixing device comprises: a brake hose fixing omnidirectional bolt which fixes by rotating into a thread on the caliper body; the brake hose seated on the brake hose fixing omnidirectional bolt; and a fixing nut which fixes the brake hose fixing omnidirectional bolt and brake hose by rotating same from the center thereof.
Claims3
A method for manufacturing a brake caliper, the method comprising:
- forming a sand core having at least one cylinder core corresponding to at least one cylinder of a caliper body;
- preparing a plurality of brake hydraulic lines, including:
- forming a cutting groove on a boundary, of each brake hydraulic line, between a first portion configured to be planted into the caliper body during a casting process and a second portion configured to be cut away from the caliper body after the casting process;
- and
- blocking an end of the second portion such that casting material is prevented from flowing into each brake hydraulic line during the casting process;
- press-inserting the second portion of each brake hydraulic line into the at least one cylinder core of the sand core prior to the casting process;
- forming the caliper body, in which the plurality of brake hydraulic lines are planted and which has a threaded hole formed thereon, using the casting process;
- removing the sand core from the caliper body after the casting process;
- cutting away, from the caliper body in which the plurality of brake hydraulic lines are planted, the second portion of each brake hydraulic line at the cutting groove;
- and
- fastening a brake hose fixing device into the threaded hole formed in the caliper body.
