A brake disc assembly includes a central drive hub and a wear disc, which includes first and second faces held together axially about the hub. Each face has a respective inner surface and is formed of at least two distinct segments. Each segment extends between two radial edges. The radial edges of the segments of one face do not extend opposite the radial edges of the segments of the other face. Each segment of the face is adapted to be secured to a segment of the other face via at least one fastening member adapted to hold said faces.

Shaped material (1), in particular a disc for a disc brake includes layers (2, 4, 6) of carbon fibers stacked in a construction direction (X). Each layer (2, 4, 6) has segments (8, 10) placed side by side and joined together to form the layer, the segments of a layer (2, 4, 6) include radial segments (8) and transverse segments (10). In each layer (2, 4, 6) of carbon fibers, the number of transverse segments (10) is greater than the number of radial segments (8). A method manufactures a shaped material.

A brake disc configured to control airflow through portions of a brake disc assembly includes a brake disc, at least one airflow restrictor, and an actuator. The at least one airflow restrictor includes at least one gate member configured to move between a closed position and an open position. In the closed position, the at least one gate member at least partially reduces airflow between a circumferential inner edge and a circumferential outer edge of the brake disc. In the open position, the at least one gate member is positioned to permit increased airflow between the circumferential inner edge and the circumferential outer edge of the brake disc, relative to when the at least one gate member is in the closed position. The actuator is coupled to the at least one airflow restrictor and configured to move the restrictor between the open position and the closed position.

A braking system for aircraft landing gear including a plurality of clamping zones for clamping a brake disk. The braking system comprises an actuator, a caliper, a rim rotatable about an axis of rotation, and the brake disk, which is floatingly mounted relative to the rim. The caliper comprises a stationary inner support, a movable intermediate support, and an outer support that is hinged relative to the inner support. Under action of the actuator, the movable intermediate support moves and causes the brake disk to move so that the brake disk is clamped between the intermediate support and the outer support, and then causes the outer support to tilt so that the brake disk is clamped between the inner support and the outer support.

A friction disk may comprise a friction disk core and a wear liner coupled to the friction disk core. A depression may be formed in a surface of the friction disk core. The wear liner may comprise a protrusion extending from a non-wear surface of the wear liner. The protrusion may be positioned within the depression of the friction disk core.

A disc/brake friction torque for railway vehicles consisting of at least one pad comprising at least one friction element and a disc. The friction element is made of a sintered material comprising copper, iron, graphite, 0.02 to 1.5% by weight of molybdenum, 1 to 3% by weight of chrome and a porosity ranging from 20 to 35%; and the disc is made of cast iron comprising 0.05 to 2% by weight of chrome, 0.05 to 2% by weight of molybdenum, 0.1 to 2% by weight of nickel.

A brake assembly for a servo including a motor includes: a brake disk fixed to and rotatable together with the output shaft of the motor of the servo, the brake disk having a lateral wall defining at least one opening; and a linear motion actuator including a plunger and an elastic member. The plunger sides from a first position where a first end of the plunger is received in the at least one opening to a second position where the first end of the plunger is disengaged from the brake disk when the linear motion actuator is energized. The elastic member applies an elastic force to cause the plunger to slide from the second position to the first position when the linear motion actuator is deenergized so as to stop rotation of the output shaft of the motor.

A friction disk includes a friction disk core having an inner diameter edge, an outer diameter edge, and a first surface with multiple mortises extending radially across the first surface, each of the multiple mortises having a different dimension at the inner diameter edge than at the outer diameter edge. The friction disk further includes a first wear liner having two wear liner segments each including a wear surface and a non-wear surface having a tenon with a complimentary shape to each of the multiple mortises, the tenon being configured to be received by a corresponding mortise of the multiple mortises to couple the wear liner segments to the friction disk core to form an annular liner.

A disk brake for a brake disk ring of an azimuth drive of a wind turbine includes a brake housing which has two housing halves that, on opposite sides, flank receiving jaws for the brake disk ring. At least two brake pistons which hydraulically act upon friction lining carriers assigned to the receiving jaws are mounted in each housing half. At least one housing half has a cleaning channel, extending from a rear side of the housing and towards a front housing area, in which the receiving jaws and the friction lining carriers are provided.
