A brake for an aircraft includes a housing, a shaft defining an axis (X) and extending into the housing, a floating brake disk on the shaft, the brake disk fixed for rotation with the shaft and arranged to be axially movable within the housing, a static brake pad arranged on a first side of the floating brake disk, a movable brake pad arranged on a second, opposite, side of the floating brake disk and biasing means for moving the movable brake pad relative to the housing to press the movable brake pad against the floating brake disk. The biasing means press the floating brake disk against the static brake pad to apply braking force to the floating brake disk. The brake also includes a thermal fuse in thermal contact with the static brake pad. The thermal fuse has a fusing temperature, T, above which the thermal fuse fuses.

A brake pad may have at least one plate. The plate may be provided with a first slot. The first slot may have a first slot edge adapted to accommodate a first pin. The first slot edge may have a first portion and a second portion, in which the brake pad has a tangential center-of-gravity plane. The first and second portions may be crossed by the tangential center-of-gravity plane so that under a reverse braking condition the brake pad rests against the first pin in at least a first contact point of the first slot. Under a forward braking condition the brake pad rests against the first pin in at least a second contact point of the first slot in which the second contact point of first slot lies in the tangential center-of-gravity plane.

A brake pad may have at least one plate and at least one friction material supported by the plate. The friction material surface may have a barycenter. The plate may have a first slot and a second slot. The first slot may have a first slot edge adapted to accommodate a first pin mounted on the caliper body. The second slot may have a second slot edge adapted to accommodate a second pin mounted on the caliper body. In a forward braking condition, the brake pad rests on the first pin with a first slot first portion, and the brake pad rests on the second pin with a second slot first portion. The first slot is arranged in a radially outer position with respect to the barycenter and the second slot is arranged in a radially inner position with respect to the barycenter. The first slot and the second slot may be radially external with respect to a barycenter circumference centered on a rotation axis and passing through a barycenter.

A compact, efficient, and reliable electromechanical actuator that is capable of driving heavy loads at a high rate of speed and also capable of resisting large back driving forces. The actuator resists tension and compression back driving forces in a static state as well as when the actuator extends and retracts. The back driving forces are resisted even if the electronics (e.g., motor) fail.

According to an aspect, there is provided an elevator car parking brake comprising a brake carrier having a first plate and a second plate, the plates being spaced from each other and positioned to enable a guide rail to travel within the space between the plates, a caliper movably connected to the brake carrier, brake pads, and an actuator configured to move the brake pads against a guide rail in a braking operation. The elevator car parking brake further comprises at least one first compression spring arranged between the first plate of the brake carrier and a brake pad directly associated with the actuator; and at least one second compression spring arranged between the second plate of the brake carrier and the caliper, the first and second compression springs being configured to keep the brake pads substantially centered with respect to the brake carrier.

To provide a rear wheel braking device for a motorcycle that can reduce an unsprung mass and the number of pieces of components on the rear wheel side of a shaft drive type motorcycle. In a rear wheel braking device for a motorcycle transmitting a drive force of a power unit of a motorcycle to a rear wheel through a drive shaft that extends in a vehicle longitudinal direction, the drive shaft includes a propeller shaft that is connected to a rear end of an output shaft through a universal joint, the output shaft protruding to the vehicle body rear side from a case member of the power unit. A brake disk is attached to the output shaft, the brake disk being braked by a rear wheel brake caliper. The rear wheel brake caliper is fixed to a bracket that is arranged in the case member, and is disposed on the vehicle body upper side of the brake disk.
