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 brake actuating device using a motor, and more particularly, to a brake actuating device capable of realizing a braking function without converting a rotational motion of a motor into a linear motion. That is, the present invention relates to a brake actuator having a fluid pressurizing member rotated by receiving a rotational force of a motor to pressurize fluid contained in a cylinder of a caliper and thereby push a piston of the caliper. Background technique [0002] A conventional type of hydraulic brake device generally includes a hydraulic circuit in which pedal pressure generated by a driver depressing a pedal is increased in a master cylinder and a force multiplier, and then transmitted to a brake device mounted to each wheel through a fluid pipe. The disadvantage of conventional hydraulic brakes is that braking cannot be achieved if the liquid pipe is damaged, and it takes a lot of time to transmit the pedal'...
