The aircraft brake vibration damper (30, 60) comprises a mesh material (30, 60) located at axially extending spaced-apart side walls (22) of a spline (12) of a torque tube (10) so that the mesh material (30, 60) is located between the spline (12) and a metal cover cap (20, 50) for the spline (12). The mesh material (60) can extend about the torque tube (10) and splines (12) and completely over a top surface (17) of each spline (12). The mesh material (80) can be located in a cavity (75) of heat shield segments (70) located between the splines (12). The mesh material (30, 60, 80) may be a knit or woven damping material (30, 60, 80) that dampens vibrations during brake operation.

Scheibenbremse für ein nutzfahrzeug

An automotive vehicle drum brake including a brake drum for connected to the vehicle wheel and a backing plate for connected to the vehicle. At least one brake shoe is and pivotally mounted with respect to the backing plate. A non-rotative nut mounted for linear motion with respect to said backing plate and has a pivotal connection with the brake shoe. A power screw is threadably engaged with the nut. An electric motor powers the power screw to turn the same to actuate the brakes. A parking brake mechanism is also provided by a coil spring which surrounds a drum which is connected with the power train from and including the electrical motor and the power screw. An actuator is provided to move the coil spring to an unwound position to allow the parking brake to release.

The friction member (4a) is actuated, via a piston mechanism (5), by an assembly consisting of a wedge (12) and of rollers (14), put into operation as a result of the rotation of a control shaft (11) driven by an electric motor (8) under the supervision of a force or pressure sensor (23) associated with one of the surfaces of ramps (16) interacting with the rollers (14).

The invention relates to a multi-disc brake comprising a stationary rotary disc (1) and a movable rotary disc (2) which is mounted on a splined sleeve (5) sliding on the hub (3) of axis (14) and with which the disc (1) is solid. An assembly of friction pads (6-9) can interact with the discs (1, 2) under the action of a hydraulic jack (13). To prevent any rattling at the start of each braking operation, elastic blocks (50) are inserted inside housings provided in the system of splines of the sleeve (5) and of the hub (3) and, when expanded, draw the flanks of the splines against one another in working contact during a braking operation.

Disc brake of the type incorporating a caliper (10) sliding on a fixed support by way of at least one axial pin (14) lying parallel to the axis of the disc (16), a brake actuator (22) acting directly upon an inner friction component (28), and, by reaction through the caliper (10), upon an outer friction component (30), the friction components (28, 30) being tangentially offset each side of a radial plane (Pr) passing through the axis of the brake actuator (22), the inner friction component (28) being anchored on the fixed support, the outer friction component (30) being anchored on the caliper (10), the tangential offset of the friction components (28, 30) being such that during forward braking (B) the caliper is subjected to a tangential force (Ft) generated by the outer friction component (30). The caliper (10) incorporates a device for positioning (32) the caliper relative to the fixed support, the positioning device (32) being progressive and dependent upon the tangential force (Ft) over a predetermined range of the force (Ft).

Device for automatically taking up play designed to be inserted between two consecutive portions of a mechanical control. The device includes two telescopic connecting parts (32, 34), which are movable in the axial sense within a fixed casing (22), and are respectively connected to consecutive portions (10, 12) of the control and releasable lock (66) which operate unidirectionally when the connecting parts move in the linear sense, characterized in that the lock comprises a component constituting a cam or eccentric (66) pivotally mounted on one of the connecting parts (32) so as to come into engagement with a surface (76) arranged opposite it on the other of the connecting parts (34) when the control is operated in an axial sense so as to provide, as a result of a wedging action, locking of the two connecting parts in the sense of linear movement.
