A method for manufacturing a disc brake, the disc brake having a brake caliper and a brake actuation mechanism being supported in it, in which the brake actuation mechanism includes an amplification mechanism for introducing a clamping force, an adjustment device for compensation of lining wear with a torque clutch, a thrust element for transmitting the clamping force onto a brake disc and a reset device, which components are arranged around a rod, in which the torque clutch is formed as a roller-ramp-mechanism. A spring force can act onto the torque clutch by means of the reset device thereby forming a torque limit.

An electric disc brake is disclosed. An electric disc brake comprises a caliper housing configured to include a cylinder at which a piston is installed to be reciprocally movable by a brake hydraulic pressure, an adjuster arranged inside the piston, a pushrod provided inside the cylinder, an actuator configured to decelerate a rotational force according to an activation of a motor to output the decelerated rotational force through an output gear so as to pressurize the piston, and a ramp unit installed inside the cylinder and configured to receive the decelerated rotational force from the actuator to pressurize the pushrod to the piston so as to prevent rotation of the pushrod.

A disk brake includes a brake disk, a brake caliper, at least one application device lying within the brake caliper on one side of the brake disk, an axially movable device configured to move a brake pad axially toward the brake disk by way of at least one actuating spindle when the brake is actuated, and an adjustment mechanism configured to rotate the actuating spindle because of a rotational coupling acting in the direction of rotation. The adjustment mechanism comprises a thread device, which, at least in the case of rotation in a second direction of rotation opposite a direction of rotation, is configured to mesh with an external thread of the actuating spindle and is configured to screw the adjustment mechanism in relation to the actuating spindle.

The present invention concerns a brake actuation mechanism for a disc brake, in which a translational movement in the direction of the brake disc leads to a rotation of an input element of an adjustment device, the input element of the adjustment device being designed as part of a ball screw drive. Furthermore, the invention concerns a disc brake with such a brake actuation mechanism.

A disk brake includes a brake disk, a brake caliper, at least one application device lying within the brake caliper on one side of the brake disk, an axially movable device configured to move a brake pad axially toward the brake disk, and an adjustment mechanism configured to be rotated about an rotation axis lying parallel to a rotation axis of the brake disk and which, in the case of rotation in a first direction of rotation bringing about adjustment, is configured to rotate the actuating spindle. The adjustment mechanism includes a thread device which, at least in a rotation in a second direction of rotation opposite the first direction of rotation, is configured to mesh with the external thread of the actuating spindle and to screw the adjustment mechanism in relation to the actuating spindle.

A disc brake includes a pressure piece, an adjusting spindle, and an adjustment unit. The adjusting spindle is guided through an opening, provided with a thread unit, of the pressure piece. The adjusting spindle is guided through the adjusting unit, and the adjusting unit protrudes into the opening. The adjusting spindle has a limitation disposed in a thread turn of the adjusting spindle.

A caliper brake for braking a moving component, including a housing and two brake shoes, which are movable within the housing toward the component to be braked, and a bearing part, which is movable within the housing by an actuator. The brake shoes each have a wedge surface on a side facing away from the component to be braked, by which a braking force acting on the bearing part is transmitted to the brake shoes with deflection and force multiplication. For higher braking forces using a spring-actuated brake, and to reduce the effects of spring travel on the braking force, the bearing part has offset bearing locations against which the wedge surfaces of each brake shoe bear. The wedge surfaces each have, in the region of the bearing locations, a step which is overcome during a closing movement of the brake shoes before they engage the component to be braked.

Disclosed herein a electromechanical brake includes a power converter including a nut provided in a cylinder portion of a caliper housing slidably coupled to a carrier and configured to rotate by receiving a driving force from an actuator, and a spindle connected to the nut and configured to move forward or backward by rotation of the nut in a first direction or a second direction; a pressing member coupled to a front side of the spindle and configured to press a pad plate; and a position adjuster screwed into the cylinder portion so that the power converter is mounted and configured to adjust a relative position of the caliper housing in response to an operation of the power converter.

An electromechanical brake apparatus includes a housing supporting an inboard brake pad and an outboard brake pad for selective frictional contact with a rotor interposed longitudinally therebetween. The housing includes a mechanism cavity located longitudinally between the inboard pad and a motor having a sun gear motor output shaft. An adjuster ramp assembly indirectly receives torque from the motor. A spindle is provided for selectively moving the inboard brake pad longitudinally. The spindle is operatively connected with the adjuster ramp assembly to indirectly receive torque from the motor therethrough. A leading ramp assembly is configured to transmit applied torque from the motor to the adjuster ramp assembly. The leading ramp assembly receives stepped-up torque from the motor via the sun gear motor output shaft and a plurality of planet gears located radially between the sun gear motor output shaft and a toothed inner lumen of the leading ramp assembly.
