A floating caliper brake device for a railroad vehicle includes: a support pin that is supported by a cylindrical portion of a support frame in such a manner as to be slidable in a direction X; a caliper; a first and second brake shoe; a pressurizing device that moves the first brake shoe back and forth; an elastic member that is expandable and contractible in the direction X; a stopper member that is immovable relatively to the cylindrical portion in the direction X; and a moving member that is frictionally engaged with the support pin so as to be slidable in the direction X.

An actuation system includes a power drive unit that drives a plurality of drive shafts that each has a first end individually connected to the power drive unit. The power drive unit includes a geartrain including a plurality of individual gears that are offset relative to each other along the gearbox, and a motor-driven rotation of one of the plurality of individual gears drives rotation of the other individual gears, and each of the plurality of individual gears rotates to drive rotation of a respective one of the plurality of drive shafts. A plurality of torque brakes is mounted to the gearbox, the torque brakes being mechanically coupled to respective individual gears and drive shafts. When the torque being passed through is above a predetermined threshold value, a locking of one of the torque brakes stops rotation of all gears simultaneously to maintain positional symmetry in the actuation system.

A tire engaging brake for use with a vehicle having a vehicle frame supporting a tire from a suspension includes a base securable to the vehicle frame, a brake pad mounting arm pivotally connected to the base, and a brake pad connected to the brake pad mounting arm. An over-center linkage has an inner link pivotally connected at an inner end to the base at a position spaced from the pivotal connection of the brake pad mounting arm to the base. An outer link of the over-center linkage is pivotally connected at an inner end to the inner link and is pivotally connected at an outer end to the brake pad mounting arm. A lever arm is cooperable with the inner link for pivoting the inner link, the outer link and the brake pad mounting arm between a retracted position and a tire engaging position in which the inner link and the outer link extend in an over-center condition.

A wet friction disc includes a friction surface and a lubrication groove through which a lubricant supplied to the friction surface flows. The lubrication groove has a plurality of circumferential groove portions that extends in a circumferential direction and a plurality of intersecting groove portions that extends in directions intersecting the circumferential direction. At least one of the circumferential groove portions has a through-hole that extends through the wet friction disc between an opposite surface facing s mating member and a surface on the opposite side in an axial direction.

A powered axle for a work vehicle with a dual wheel arrangement includes an axle housing, an axle hub mounted to the axle housing, and an output hub having opposite axial ends supported by one or more wheel bearings for rotation about the axle hub along a rotation axis. An electric drive is disposed, at least in part, within the axle housing, and a hub gear set is disposed, at least in part, within the axle hub and configured to transmit power from the electric drive to the output hub for rotation of the dual wheel arrangement. A wheel brake disposed radially between the axle hub and the output hub and axially between the ends of the output hub is configured to selectively permit and arrest rotation of the output hub.

A vehicle brake (2, 102), in particular a utility vehicle compressed-air disc brake, includes a brake caliper (4, 104), a pressure piece guide (8, 108), which is arranged in the brake caliper (4, 104), and a pressure piece (6, 106), which is guided in the pressure piece guide (8, 108) along a movement axis (10, 110). The pressure piece guide (8, 108) is designed as a recess (12, 112), and the pressure piece (6, 106) has an outer contour (14, 114) corresponding to the recess. The pressure piece guide (108) and/or the outer contour (14) of the pressure piece are/is divided, on both sides of the pressure piece (6), into a plurality of curved, mutually spaced partial surfaces (16, 116).

A torque limiter (TL) is provided for torque transmission (TT) to downstream components. The TL includes an input shaft, an output shaft and a torsional spring which is preloadable by a preload torque whereupon the torsional spring is fittable about the output shaft with the output shaft fit about the input shaft. For input shaft rotation, first TT paths proceed from the input shaft to the output shaft through the torsional spring when downstream torque of the downstream components deceeds the preload torque and a second TT path proceeds from the input shaft to an external structure when the downstream torque exceeds the preload torque.

An example rotational joint assembly for a robotic medical system, the rotational joint assembly comprising at least one arm segment and a rotational joint provided at one end of the arm segment. The rotational joint is to allow the arm segment to rotate about a rotational axis. The rotational joint comprising a brake to lock rotation of the arm segment at the rotational joint and an actuator to selectively engage or disengage the brake. The actuator comprising a cam having two stable regions separated by two transition regions, the two stable regions comprising a first stable region corresponding to engagement of the brake and a second stable region corresponding to disengagement of the brake.

There is provided an indicator for a torque limiter, comprising one or more resilient members configured to move from an initial, compressed state during normal operation of the torque limiter, to a subsequent, expanded state upon tripping of the torque limiter, to provide a visual indication that the torque limiter has tripped.

A tension brake assembly includes a frame, a plurality of brake pad assemblies, and a hub configured to be coupled to a rotating component. The hub includes a plurality of drive pins adjacent an annular wall. A rotor engages the plurality of drive pins such that rotation of the hub causes rotation of the rotor while permitting axial movement relative to the annular wall. The rotor has friction surfaces for engagement with the brake pad assemblies. An actuator is provided. Movement of the actuator in a first direction moves the friction components together in the axial direction to increase friction exerted by the tension brake assembly. Movement of the actuator in a second direction moves the friction components away from one another in the axial direction to decrease friction exerted by the tension brake assembly.
