7results about "Mechanically actuated brakes" patented technology

A method for electronic air gap control of an electrical motor vehicle brake system comprises electrical wheel brakes, wherein a resting position is adopted and maintained by supplying electric energy. Mechanical elements for adjusting the resting position can thus be dispensed with. Furthermore, an electrical motor vehicle brake system comprising electrical wheel brakes for carrying out such an electronic air gap control method is described.

The present invention is entitled "Electric Brake." In some examples, the present invention provides a brake assembly including an actuator assembly configured to cause translation of a piston to compress a disc stack. The actuator assembly is configured to generate a first torque about a motor axis using a motor and a second torque from the first torque using a harmonic drive. The actuator assembly can include a gear set configured to cause a linear actuator to translate the piston using the second torque. In some examples, the actuator is configured to translate the piston along a compression axis that is different from the motor axis.

A brake actuator plate assembly includes an electromechanical brake actuator, a connector configured to communicatively couple with an aircraft, a wire harness configured to terminate at the connector and conduct at least one of a voltage or a current to and from an actuator motor, and an actuator plate comprising a wire harness channel configured to house the wire harness.

axle with an axle housing (1) having an axle housing flange (14) and with a brake unit which is arranged in the axle housing, wherein the axle has two shafts (2, 3) rotatable about a common axis of rotation (20), wherein the brake unit comprises: - an electromagnet unit (4) with at least one coil (5, 6) for generating a magnetic field; - at least one spring element (10, 11); - at least one brake rotor (12, 13) per shaft (2, 3), which is rotationally fixed to the corresponding shaft (2, 3), but is axially displaceable thereon; and - at least one magnetizable armature element (8, 9); where - the electromagnetic unit (4) is fixed in position in the axle housing (1); - the magnetizable armature element (8, 9) and the brake rotors (12, 13) are arranged between the electromagnet unit (4) and the axle housing flange (14); - the magnetizable armature element (8, 9) is arranged axially displaceable but non-rotatable in the axle housing (1) between the brake rotors (12, 13) and the electromagnet unit (4) along the axis of rotation (20); and - the spring element (10, 11) is arranged and supported in such a way that it pre-tensions the anchor element towards the brake rotors (12, 13) to provide a braking force, characterized in that, in order to generate a braking force, the current flow through one or both of the coils (5, 6) is reduced, thereby reducing the attractive force on the corresponding magnetizable armature element (8, 9) or on both magnetizable armature elements (8, 9), wherein, when the attractive force becomes sufficiently low, the corresponding magnetizable armature element (8, 9) is pressed by the corresponding spring element (10, 11) towards an axially displaceable force transmission element (7), which displaces accordingly towards a first of the brake rotors (12), which, due to its displaceability, is in turn displaced towards a displaceable friction element (16), which in turn is displaced towards a second of the brake rotors (13), whereby corresponding frictional forces occur between the axle housing flange (14), the second brake rotor (13), the friction element (16), the first brake rotor (12) and the force transmission element (7), which cause braking and, if necessary, complete locking of the rotatable shafts (2, 3). wherein the electromagnet unit (4) is firmly connected to the axle housing (1) and / or the axle housing flange (14), in particular by screwing.

An electromagnetically switchable brake is described, which comprises a curved element in the form of a curved ring (16) or a curved ring segment (18) for suppressing switching noise of a fail-safe brake and a working current brake, the curved element being arranged between a coil support (1) and an armature disc (2) and acting there as a resilient element, wherein the axial length (L) of the curved element is greater than its radial width (B).

The invention relates to a vehicle brake disc (1) comprising a peripheral annular ring (100) having two friction faces, and a central fixing bowl (200) integral with said ring, said central bowl comprising an annular flange (210), an annular ring (220) extending in the direction of said ring from the outer peripheral edge of said flange, and a peripheral rim (230) projecting radially from the outer side from the distal end of said ring opposite said flange; said brake disc further comprising several assembly inserts (300) made of polymer material, fitted onto corresponding notches formed on the outer periphery of said rim, and further comprising holes through which the threaded rods of screws (V) also pass through respective holes formed in said ring and screwed onto nuts so as to ensure the clamping of said central bowl to said ring.Figure to be published with the abbreviation: Fig. 1.
