An actuator gearbox includes a drive shaft including a plurality of gear linkages that are spaced apart along the drive shaft, and a plurality of output shafts adjacent respective ones of the plurality of gear linkages. Each of the gear linkages includes a fixed gear coupled to one of the plurality of output shafts and a moving gear that is slideably coupled to the drive shaft. A bias spring is coupled to the moving gear to urge the moving gear out of engagement with the fixed gear. The mechanical switch moves the moving gear into engagement with the fixed gear on the output shaft adjacent the linkage to thereby cause the output shaft to rotate in response to rotation of the drive shaft.

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.

A no-back device for resisting feedback torque from an actuator. The no-back device comprises: a flange arranged to receive torque via a shaft; a ratchet assembly comprising a ratchet wheel arranged parallel to the flange; and a braking assembly comprising a resistance wheel, which is sandwiched between the flange and the ratchet wheel, and a braking device, which acts on the resistance wheel to generate a resistive angular force reacting against torque exerted on the resistance wheel. The braking device comprises a follower arranged to roll, under bias from a spring in the braking device, on a cam surface extending around a circumferential perimeter of the resistance wheel. Radial displacement of the follower energizes the spring to generate resistive angular force.

A brake system includes a brake disc, rotary movable around a disc axis, and a brake mechanism. The brake mechanism includes a brake pad, movable in a first direction, a cylinder having a piston movable in a second direction, a lever rotary movable around a lever axis, the lever being connected to the piston, a cam element, arranged to convert a rotary motion of the lever around the lever axis, into a translation motion in the first direction, and a rod, expanding between the brake pad and the cam element. The lever, the cam element and the rod are housed in a housing. Considering a plane including the disc axis and the first direction, the lever axis is inclined relative to the plane, at an angle different from 90°.

A disc brake for a commercial vehicle has a brake caliper spanning a brake disc on the vehicle side, in which brake caliper a clamping device is arranged which has a pivotable brake lever engaging in at least one bridge carrying a brake plunger, which at the same time is directly or indirectly supported at the inner side of a wall of the brake caliper. The contact area of the bridge at the brake lever or of the brake lever at the brake caliper is configured as a pivot bearing having a bearing shell cross-sectionally configured as an arc forming a part of the pivot bearing. The bearing shell is placed in a seating. The disc brake is configured such that the bearing shell is located in the pivoting direction of the brake lever with its opposite longitudinal borders at stop edges, which longitudinally limit the trough-shaped seating.

A brake apparatus includes a coupling member configured to couple one end parts of a pair of link arms, an actuator mounted on the coupling member and configured to advance and retract an output member, a lever rotatably coupled to the output member and configured to rotate by advancing and retracting movements of the output member and a booster unit provided on at least one of the one end parts of the pair of link arms and configured to rotate the link arms with supporting portions as fulcrums by boosting a force transmitted by the rotation of the lever.

A system and method of adjusting a zero reference may comprise retracting ram of an actuator coupled to a load cell from a first position to a second position. The system and method may comprise reporting a measurement by a load cell, in response to the actuator being in a second position. The system and method may comprise calculating a force being measured by t the load cell. The system and method may comprise creating a zero reference offset value based on the calculation, in response to the force calculation resulting in a non-zero force calculation. The system and method may comprise adjusting a zero reference value of the load cell by the zero reference offset value.

A brake device includes a brake caliper with a first frictional surface and a first actuation surface, a pressing part of the brake device being linearly guided along a first straight line on the brake caliper. The pressing part has a second frictional surface and a second actuation surface, a region being provided between the first frictional surface and the second frictional surface for arranging a brake element. The brake device has a rotatable spreading element which interacts with the first actuation surface and the second actuation surface. During a rotation of the spreading element, the rotation occurring in order to actuate the brake device, a first spreading element surface is in direct contact with a first rolling surface and rolls substantially on the first rolling surface, and the first rolling surface corresponds to the first actuation surface or the second actuation surface.

An electromechanical brake actuator (102, 202, 302, 402) for a brake, in particular a commercial vehicle disc brake, has an electric motor (106, 206) for generating a drive torque, a cam disc (108, 208, 308, 408) operatively connected to the electric motor (106, 206) and mounted in a rotationally movable manner, and a brake plunger (114, 214, 314) which can be moved along a plunger axis for the actuation of a brake lever (358) of the brake (368). The cam disc (108, 208, 308, 408) and the brake plunger (114, 214, 314) have contact faces which are in contact with one another and slide or roll on one another for the direct transmission of the drive torque between the cam disc (108, 208, 308, 408) and the brake plunger (114, 214, 314).
