A self-adjusting brake having a brake drum, primary and secondary brake shoes, a brake cylinder and a stationary brake shoe support for floatingly mounting the brake shoes. The latter are arranged interiorly of the brake drum and coact with it, the ends of the brake shoes being curved and pressed against the brake cylinder and the brake shoe support by means of return springs which also serve to lift the brake shoes off the brake drum when the brake is in non-actuated condition. Each brake shoe ...

A brake comprises a ring-shaped housing formed of sheet metal halves secured together and forming openings for receiving pins. The pins slidably support braking plates that are normally biased apart and are movable for engagement with the opposite surfaces of a brake disc. The housing halves also provide an opening for receiving an actuating lever that is engageable with one of the braking plates. The housing may be shiftably mounted on a fixed mounting plate for use with an axially fixed rotati...

A brake mechanism, particularly for trucks and buses, of the type wherein each shoe is independently anchored by a separate anchor pin, wherein the anchor pin of the secondary shoe is modified to have a generally eccentric cross-sectional configuration. The pin fits within a circular hole in the brake shoe, and the arrangement is such as to permit the shoe, when operating as a secondary brake shoe, to move outwardly at its end adjacent the anchor pin in a direction toward the brake drum when act...

The invention relates to a brake gear for a disc brake serving to transfer a force to a brake pad that acts upon a brake disc. The brake gear is accommodated in a brake caliper of the disc brake and comprises both a pressing element, which interacts with the brake caliper, as well as a rod. The pressing element is mounted in the housing of the brake caliper with the aid of the rod in such a manner that it is parallel to the rotation axis of the brake disc.

The invention relates to a brake disk for a disk brake, in particular for utility vehicles. Said brake disk comprises two spaced friction rings, which are linked to each other forming an air space and is linked to a wheel hub and/or axle in a rotationally fixed manner. Said brake disk is designed, such that it is fixed to the hub, by means of a separate link piece radially extending, in a manner that said disk can be elastically displaced in the hub axial direction.

The invention relates to a brake disc for a rail vehicle, with which a hub body (16) and a brake ring (12) are connected to one another such that with braking procedures a thermal expansion of the brake ring (12) relative to the hub body (16) is possible. At the same time screws (15) pass through axially aligned openings in a hub flange (14) arranged on the hub body (16) and a brake ring flange (13) arranged on the brake ring (12). According to the invention the screws at their end exiting the b...

A pad for a disk brake comprising a plate for supporting a friction lining which can come into contact, at the braking stage, with a disk associated with the brake is characterized in that the pad comprises weights associated rigidly with the plate for varying the mass of at least one portion of the plate so as to achieve an inertia of the pad that substantially prevents vibrations of the pad which could cause noise of the disk brake during braking.

A brake lining of a vehicular brake device is produced by a friction material which has a characteristic that a friction coefficient of the friction material decreases according to an increase of a sliding speed between the brake lining and a rotational member when the sliding speed is greater than or equal to a predetermined speed during the braking operation, and the friction coefficient is substantially constant when the sliding speed is smaller than the predetermined speed.

A brake shoe assembly (1) for a drum brake, the brake shoe assembly being a single-piece construction and including a brake shoe (2) of generally circular form having two separate and opposed ends (17, 18), and defining a pair of friction lining mounting sections (11, 12) disposed on opposite sides of the brake shoe (2). The friction lining mounting sections (11, 12) have a T-shaped cross-sectional form defining an arcuate, radially outer platform (15) for mounting a friction lining (16) and a r...

A drum brake comprising a plate on which at least one shoe having a friction lining is mounted. A lever moves the shoe against a wheel drum in response to a braking command to effect a brake application. A resilient return spaces the shoe apart from the drum when braking ceases. The shoe is mounted to slide along an essentially radial axis between two guide walls secured to the plate The lever for applying the shoe bears against the inside wall of the shoe for exerting a substantially radial for...
