The brake assembly includes a housing, a rotor disc. The rotor disc includes at least one internal cavity. The at least one internal cavity includes a pawl and a thermal fuse. In use, the thermal fuse is configured to maintain the position of the pawl in the at least one internal cavity when a temperature is below a predetermined threshold, and wherein the thermal fuse is configured to melt when a predetermined threshold of temperature is reached during braking to release the pawl out of the at least one internal cavity towards the housing. The housing includes at least one recess configured to receive the pawl.

Disclosed is a brake system for a railroad vehicle, including a parking brake provided with a piston and having a first configuration in which the piston is in a working position in which it acts on a lining support and applies a predetermined force to a brake disc; a second configuration in which the piston is in a rest position in which it does not act on the support and does not apply any force to the disc; and a third configuration in which, when the vehicle is not at a standstill and the ambient temperature in the environment of the disc is greater than a threshold value, it forces the piston to move towards a trip position different from its working and rest positions, in order to limit or cancel the force applied to the disc.

A magnetorheological braking device has two braking components that are continuously rotatable relative to one another. A first braking component extends in the axial direction and the second braking component includes a hollow casing extending around the first braking component. A peripheral gap is filled with a magnetorheological medium. The first braking component has an electric coil and a magnetically conductive core which extends in the axial direction. A star contour with magnetic field concentrators on the core and/or on the shell part project into the gap, which results in a peripheral gap region with a variable gap height. The electric coil is wound around the core such that a magnetic field runs through the core and the magnetic field concentrators and through the gap into a wall of the casing. A star contour is formed by a stack of star plates.

An elevator braking device and an elevator system are provided by the present disclosure. The elevator braking device includes: a fixed frame; a floating bracket, which is disposed on the axial guide of the fixed frame and movable along the axial guide; a movable plate supported by the floating bracket, the movable plate having a second friction plate on a second side of the brake disc; an actuator; and a position self-adjusting member which includes a magnetic portion to act on the magnetic member on the floating bracket such that after the braking state is released, the floating bracket tends to move towards a balanced position, thereby reducing a difference between a first gap G1 between the first friction plate and the brake disc and a second gap G2 between the second friction plate and the brake disc.
