There is provided an apparatus for applying a braking force to a brake disc using a brake pad. The apparatus comprises a lever configured to rotate about a first fulcrum, and a pressing member attached to said lever and for urging a brake pad against a brake disc. A component is arranged and configured to ensure that said pressing member has a circular translational movement upon rotation of said lever, and a rotatable input member is configured to rotate a first member. In use, rotation of said first member causes movement of an actuating member along an first axis (A), and said axial movement of said actuating member causes said lever to rotate about said first fulcrum for applying a braking force to said brake disc.

A brake apparatus includes a first coupling member coupled to one end part of one of a pair of link arms, a second coupling member coupled to the one end part of the other of the pair of link arms to freely advance and retract with respect to the first coupling member, an actuator configured to advance and retract an output member, a lever rotatably coupled to the output member and configured to be rotated by advancing and retracting movements of the output member and a booster unit configured to advance and retract the second coupling member with respect to the first coupling member by boosting a force transmitted by the rotation of the lever.

A bicycle brake assisting apparatus may comprise a main body, a traction apparatus, two control cable members, a rear brake tube, and a front brake tube, and the traction apparatus further comprises an operating block and a rotating piece which are pivotally connected with each other. The bicycle brake assisting apparatus of the present invention is configured to achieve the effect of stopping the rear wheel of the bicycle first and concurrently stopping the rear wheel and the front wheel of the bicycle thereafter regardless of pulling a left brake lever, a right brake lever, or both of the brake levers of a bicycle, thus increasing safety of use for a cyclist.

A brake apparatus for restricting rotation of a rotatable member of a mowing machine, thereby controlling rotation of a wheel of the mowing machine, includes a brake member fixable on the rotatable member, and a gripping member for engaging and disengaging the brake member for restricting or permitting rotation of the rotatable member. A thrust link is coupled to the gripping member such that movement of the thrust link causes the gripping member to engage or disengage a radially outer surface of the brake member. For example, the gripping member may be biasedly engaged with at least a partial circumferential extent of the brake member such that actuation of the thrust link causes disengagement of the gripping member from the brake member.

An expansion device for drum brakes, which is floatingly and approximately centrally arranged between two substantially symmetrical brake shoes, the expansion device including at least two gear levers articulated to each other and each supported on a brake shoe, at least one of the gear levers of the expansion lock being coupled to an actuating element of an actuator system such that the brake shoes carry out an even, translationally directed expanding movement, which is converted by a gearing, in the direction of the brake drum. At least one of the gear levers of the spreader lock has a spring element integrated into it that can be elastically reversibly deformed by a brake application force about a defined elasticity S of at least 1 mm in a defined manner.

The invention relates to an operating apparatus for a brake, having an actuator unit with a linearly mobile actuator element, an actuating unit with a linearly mobile actuating element by means of which a braking element can be moved relative to a brake disc or a brake drum, and a transmission unit for transmitting a force from the actuator element to the actuating element. The transmission unit has a deflection device by means of which the force which is transmitted from the actuator element to the actuating element can be deflected from a first direction into a second direction.

A motor vehicle drum brake (10) includes: two braking segments (18A, 18B); an anchoring element (28) including two bearing surfaces (32A, 32B) of two second ends (24) of the braking segments (18A, 18B); a wheel cylinder (34) which, in a first simplex operating mode, is suitable for transversally separating the adjacent first ends (22) of the segments (18A, 18B); the anchoring element (28) including: a fixed body (42) wherein two sliding pistons (50A, 50B) each carry a bearing surface (32A, 32B); and elements (44) for separating the pistons (50A, 50B) between an anchoring position wherein they abut against the body (42), and a sliding position wherein the pistons (32A, 32B) are separated to allow the sliding thereof during operation in so-called servo-dual mode.

A vehicular parking brake includes a braking device, a linear actuator, a first tie rod connected to the linear actuator, a second tie rod connected to the braking device, and a motion transmitting mechanism connecting the first tie rod to the second tie rod with a variable transmission ratio that varies based on a reaction force produced by the braking device.

Apparatus to provide motor backdrive resistance are described. An example apparatus described herein includes a brake to engage an output shaft of a motor. The example apparatus also includes a brake release arm operably coupled to the brake. A reaction arm is fixed relative to the brake release arm and operatively coupled to the motor. The reaction arm causes the brake to disengage the output shaft of the motor in response to a reaction torque of the motor.

A brake apparatus includes a first coupling member coupled to one end part of one of a pair of link arms, a second coupling member coupled to the one end part of the other of the pair of link arms to freely advance and retract with respect to the first coupling member, an actuator configured to advance and retract an output member, a lever rotatably coupled to the output member and configured to be rotated by advancing and retracting movements of the output member and a booster unit configured to advance and retract the second coupling member with respect to the first coupling member by boosting a force transmitted by the rotation of the lever.
