Abstract
A brake device that pressurizes a brake pad as brake fluid in a master cylinder operates a caliper piston by a master piston that operates by receiving power of a driving motor of a brake module kit in the present disclosure applies a brake module kit to various types of caliper bodies and commonizes the brake module kit.
Claims10
A brake device comprising:
- a caliper body;
- a brake pad disposed within the caliper body;
- a caliper piston configured to press the brake pad;
- a caliper cylinder containing the caliper piston;
- and
- a brake module kit connected to the caliper cylinder and including:
- a master cylinder containing brake fluid;
- a master piston disposed within the master cylinder;
- and
- a driving motor configured to linearly move the master piston within the master cylinder,
- wherein the master piston, when moved by the driving motor, pressurizes the brake fluid in the master cylinder to flow to the caliper cylinder, and a pressure in the caliper cylinder generated by the brake fluid in the caliper cylinder causes the caliper piston to press the brake pad.

A vehicle comprising:
- a vehicle body;
- a plurality of wheels configured to rotate, each wheel including a brake disc;
- and
- a plurality of brake devices respectively disposed on the plurality of wheels and respectively in contact with the brake discs to limit rotation of the plurality of wheels,
- wherein at least one of the plurality of brake devices includes:
- a caliper body;
- a brake pad disposed within the caliper body;
- a caliper piston configured to press the brake pad;
- a caliper cylinder containing the caliper piston;
- and
- a brake module kit connected to the caliper cylinder, wherein the brake module kit includes:
- a master cylinder containing brake fluid;
- a master piston configured to move linearly in the master cylinder;
- and
- a driving motor configured to move the master piston,
- wherein, when moved by the driving motor, the master piston pressurizes the brake fluid in the master cylinder to flow to the caliper cylinder, and a pressure generated by the brake fluid in the caliper cylinder causes the caliper piston to press the brake pad.
