Abstract

A brake actuating apparatus includes a caliper body with a cylinder. An electric motor is fixed to the caliper body. A piston is installed in the cylinder. A plug and a rotational shaft are installed in the cylinder to be rotated by the motor. A head is attached to the rotational shaft and the plug defines a fluid-receiving space. The rotation of head varies the volume of a fluid contained in the fluid-receiving space, thereby moving the piston.

Description

Technical field [0001] The present invention relates to a braking device using a motor, and more specifically, to a braking device capable of realizing a braking function without converting the rotational motion of the motor into linear motion. That is, the present invention relates to a brake device having a fluid pressurizing member that rotates by receiving the rotational force of a motor to pressurize the fluid contained in the cylinder of the caliper and thereby push the piston of the caliper. Background technique [0002] Generally, the conventional hydraulic brake device includes a hydraulic circuit, in which the pedal pressure generated by the driver's stepping on the pedal is increased in the master cylinder and the multiplier, and then transmitted to the brake device installed on each wheel through a liquid pipe. The disadvantage of traditional hydraulic braking is that braking cannot be achieved if the fluid pipe is damaged. It takes a lot of time to transmit the pedal...
