Disclosed is an electric caliper brake. The electric caliper brake includes a carrier including a pair of pad plates installed to be moveable forward and backward, a caliper housing configured to be installed to be slidable on the carrier and to have a cylinder in which a piston of which an inside is dug in a form of a cup is moveable forward and backward due to a brake hydraulic pressure, a power conversion unit including a spindle member installed to pass through a rear of the cylinder and rotating due to a rotational force delivered from an actuator and a nut member screw-coupled to the spindle member, disposed in the piston, moving forward and backward according to rotation of the spindle member, pressurizing the piston, and releasing the pressurizing, and a filling member configured to be disposed in the piston in such a way that rotation of the filling member is limited, the filling member being coupled to the nut member.

Electric caliper brake

Disclosed herein is an electric disk brake including: a carrier in which a pair of pad plates for pressing both sides of a rotating disk together with wheels are installed to make advance and retreat; a caliper housing that is slidably installed in the carrier and has a cylinder in which a piston is installed to make advance and retreat due to brake hydraulic pressure; an adjuster disposed in the piston; a push rod that is installed in the cylinder and is screw-coupled to the adjuster; a ramp unit that is installed to penetrate the rear of the cylinder, converts a rotation motion into a rectilinear motion by receiving a rotation force from an actuator that generates a parking brake force, and presses the push rod toward the piston; and an elastic member that is disposed in a spring case formed between an inner circumferential surface of the cylinder and the push rod and provides an elastic force to the push rod, further including a connector having one end coupled to a rotating ramp plate of the ramp unit so that the connector is rotated together with the rotating ramp plate, and having the other end connected to a final output gear among a plurality of gears configured to decelerate a rotation force generated from the actuator so that the rotation force is transferred only in a direction in which a brake force is generated in the rotating ramp plate, wherein at least one hole is spaced by a predetermined distance apart from a center of the connector in a radial direction and is formed in an arc shape, and protrusions are formed in the final output gear to penetrate the at least one hole and to rotate, and the connector includes: a first coupling part that penetrates a center of the final output gear and is coupled to the rotating ramp plate; and a second coupling part, which extends from the first coupling part in a radial direction and in which the at least one hole is formed in the radial direction of a center of the second coupling part.

Electric disk brake

Disclosed is an electronic disc brake. The electronic disc brake includes a caliper housing at which a piston is installed, a carrier coupled with the caliper housing, a pair of pad plates installed at the carrier to be slidable toward a disc, an adjuster to prevent the pad plates from moving away from the disc and maintain the pad plates at a certain distance from the disc, a push rod screw-coupled to the adjuster, a spindle unit coupled to the push rod and installed at a cylinder of the caliper housing, a spring case forming an accommodation space between the cylinder and the push rod, a low-pressure spring and a high-pressure spring arranged in parallel in the spring case, and a support plate slidably installed in the cylinder so that a gap is formed between the low-pressure spring and the high-pressure spring in the longitudinal direction.

Electronic disc brake

Disclosed is a disc brake including a carrier on which a pair of pad plates are movably installed and a caliper housing, which is slidably installed on the carrier and is provided with a cylinder having a piston mounted so as to move forward and backward by a hydraulic braking pressure, the disc brake including: an adjuster installed in the piston to prevent the pad plates from moving away from a disc and to maintain the pad plates at a constant distance from the disc; a push rod installed in the cylinder, a front portion thereof being screw-coupled to the adjuster and a rear portion thereof being provided with a flange extending toward an inner circumferential surface of the cylinder; a ramp unit into which the rear portion of the push rod is inserted and which is installed in the cylinder and compresses the push rod toward the piston in cooperation with a parking cable to prevent rotation of the push rod; a spring case having an end portion of one side thereof fixed to the cylinder and forming a predetermined accommodation space between the inner circumferential surface of the cylinder and the push rod; a first elastic member and a second elastic member arranged in series with each other in the accommodation space of the spring case to provide elastic force to the push rod; and a support plate supported by an end portion of the ramp unit and interposed between the first elastic member and the second elastic member.
