Abstract: Disclosed is a disc brake for a vehicle, such as an electronic wedge brake, capable of preventing a disc from being subject to the moment due to misalignment of inner and outer friction members with respect to a disc. The disc brake includes a disc rotating together with a vehicle wheel, inner and outer friction pads disposed at both sides of the disc, respectively, a wedge unit installed at rear sides of the inner and outer friction pads to press the inner and outer friction pads against the disc, a driving device that operates the wedge unit for a braking operation, and a sync member for synchronizing braking positions of the inner and outer friction pads with respect to the disc. Since the disc is prevented from being subject to the moment, uneven wear does not occur in the friction member and/or the disc and deformation of the disc is prevented.

Abstract: An elevator car braking apparatus includes a gear drive assembly for compressing one or more springs which are coupled by a cam follower to one or a pair of brake shoes. When the springs are released from a compressed state, the brake shoes engage and grip hoisting ropes, part of the hoisting apparatus or the car guide rails, within a predetermined time from the start of a brake application cycle. During a brake application cycle, the springs move the cam follower along cam surfaces shaped and disposed to cause the cam follower to move at least one of the brake shoes toward the other brake shoe. The gear assembly includes clutch means for disengaging from and engaging with a gear or axle of the gear assembly during decompression and compression of the springs, respectively. A resilient material in the braking apparatus initially accelerates movement of the cam follower when the springs begin to decompress, and may protect gears of the gear assembly from damage at the end of a brake release cycle.

Abstract: In a brake system, when setting a control origin position for a resolver for detecting a moved position of a booster piston, communication between a master cylinder and wheel cylinders is interrupted by cut valves. Thereafter, the booster piston is moved forward by an electric actuator in a direction in which a hydraulic pressure is generated so that a position detected by the resolver upon detection of generation of the hydraulic pressure by a hydraulic pressure sensor (position at a time of generation of hydraulic pressure) is obtained. A position obtained by moving backward the position at the time of generation of hydraulic pressure by a predetermined amount is set as the control origin position.

Abstract: A brake assembly includes a brake pad, a bracket supporting the brake pad and having a first portion, a second portion spaced apart from the first portion, and a linkage interconnecting the first and second portions. The linkage is configured to transfer tensile loads between the first and second portion, but is characterized by the absence of any bending modes. The absence of bending modes prevents excitation of the linkage, thereby reducing sound generated during application of the brake assembly.

Abstract: A piston with a piston rod coupled thereto is inserted in a cylinder, which sealingly contains oil. An oil flow generated by movement of the piston is controlled by a damping force generation mechanism, thereby generating a damping force. A separator tube is disposed around the cylinder, and the oil is transmitted to the damping force generation mechanism through a branch tube integrally formed on a cylindrical sidewall of the separator tube. The branch tube is tapered at the outer circumferential portion thereof with the outer diameter thereof reducing toward the distal end of the branch tube.

Abstract: The present invention provides a heat dissipation plate which includes a heat dissipator and two elastic plates. The heat dissipation plate is adapted to be disposed in a bicycle disc brake. The elastic plates are fixed to the heat dissipator, and the elastic plates are disposed in the bicycle disc brake so as to fix the back panels of the brake linings in the disc brake. Thereby, the elastic plates of the present invention can conduct the heat, which is generated when braking, to the heat dissipator, so that it can prevent the brake linings from overheating when braking. The overheated brake linings may make the disc brake fail to stop the bicycle; therefore, the present invention can enhance the safety of the bicycle disc brake.

Abstract: Provided is an electric brake capable of accurately estimating the brake pad temperature and securing a sufficient braking force and response. An electric brake has a disc rotor rotating with a wheel, an actuator for rectilinearly actuating a piston in the axial direction of the disc rotor by using an electric motor, a drive controller for controlling the drive of the actuator, a brake pad pressed by the piston to give a frictional resistance to the disc rotor in the direction of rotation, and a braking start position detector for detecting a braking start position of the piston where the disc rotor is brought into contact with the brake pad. The drive controller stores the braking start position detected by the braking start position detector as the maximum braking start position. When the braking start position shifts in the pressing force-increasing direction, the drive controller updates the value stored as the maximum braking-start position.
