Abstract: A wedge-operated brake apparatus includes a piston for generating a braking force when axially driven, an actuator for generating a linear brake-actuating input, and a wedge transmission mechanism for converting the linear brake-actuating input into a brake-actuating output in the axial direction of the piston. The brake-actuating output is transmitted to the piston so as to drive the piston to thereby generate a braking force. The wedge transmission mechanism includes a first plate member which moves together with the piston, a second plate member disposed in opposition to the first plate member and fixedly secured to a housing, a wedge member disposed between the first and second plate members and engaging respective engaging surfaces of the first and second plate members via rollers, and a holder for rotatably holding the rollers and holding the wedge member while allowing linear movement of the wedge member. When the wedge member moves linearly, the holder moves, while being guided by the first and second plate members.

Abstract: A wedge-operated disc brake apparatus includes a piston for pushing a brake pad toward a brake rotor when driven, an actuator for generating a linear brake-actuating input, a wedge transmission mechanism for converting the linear brake-actuating input into a brake-actuating output in the axial direction of the piston, and an automatic gap adjusting mechanism for automatically adjusting a gap between the brake pad and the brake rotor during a non-braking state. The automatic gap adjusting mechanism includes an adjusting wheel having ratchet teeth and provided on an outer circumference of an end portion of the piston, the end portion being toward the wedge transmission mechanism, an adjusting nut provided on an inner circumference of the piston, an adjusting lever having a pawl which is formed on an end of the lever and is engaged with the ratchet teeth of the adjusting wheel, the adjusting lever being rotated via a spring by means of the brake-actuating input so as to rotate the adjusting wheel, and an adjusting bolt threadingly engaged with the adjusting nut and engaged with the brake pad to thereby be prevented from rotating.

Abstract: An electric brake apparatus includes an electric motor which generates a rotational drive force. A gear train is driven by the electric motor and generates a rotational drive force. A screw feed mechanism is driven by the gear train and converts the rotational drive force from the gear train into a linear drive force. A wedge transmission mechanism is driven by the screw feed mechanism and converts the linear drive force from the screw feed mechanism into a linear drive force transverse to the linear drive force from the screw feed mechanism. A piston is driven by the wedge transmission mechanism in an axial direction of the piston and generates a braking force.

Abstract: A wedge-operated disc brake apparatus includes a piston accommodated within a cylinder portion to be slidable along an axial direction of the piston and adapted to push a brake pad toward a brake rotor, an actuator for generating a linear brake-actuating input, and a wedge transmission mechanism for converting the linear brake-actuating input into a brake-actuating output in the axial direction of the piston. The brake-actuating output is transmitted to the piston so as to cause the piston to push the brake pad toward the brake rotor. A resilient member is provided in order to axially urge the piston toward a direction away from the brake pad. A bearing may be provided between the piston and the cylinder portion in order to enable smooth axial movement of the piston.
