A brake module for a drive system, in particular for doors, including at least one thrust washer and at least one brake disc, wherein the at least one thrust washer and the at least one brake disc each have at least one friction surface rubbing against each other during braking operation is provided. The embodiments also relate to a drive system, in particular for doors, including such a brake module. The embodiments further relate to a production method for a brake module of the abovementioned type. Known brake modules have a high variation in the braking force on the one hand in the course of their service life and on the other hand as a function of the temperature.

A brake disc for a wheeled vehicle; said brake disc including opposing annular braking surfaces; each of said surfaces provided with an identical pattern of disparate arcuate groove segments; said groove segments arranged in groups oriented in both clockwise and anti-clockwise directions; each of said groups including, one series of at least two arcuate groove segments lying along a common arc extending from proximate a hub of said braking surface to proximate the periphery of said braking surface, one inward arcuate groove segment extending from proximate said hub to a point intermediate said hub and said periphery, and one outward arcuate groove segment extending from a point intermediate said hub and said periphery to proximate said periphery.

A braking band has a first plate and an opposite second plate having inner surfaces delimiting a gap, outer surfaces forming braking surfaces, and a plate body. The plates are joined by connecting elements. At least one plate has at least one ridge projecting into the gap without reaching the opposite plate. The ridge extends from a first connecting element to an adjacent connecting element, and along a circumferential direction, the connecting elements and the ridge being groupable in modules circumferentially distributed along the gap. A first module has three adjacent connecting elements connected by two ridges projecting from the first plate into the gap without reaching the second plate. A second module has three adjacent connecting elements connected by two ridges projecting from the second plate into the gap without reaching the first plate. A third module has at least one connecting element free of ridge connection.

The present disclosure relates to a brake drum for a drum brake for a vehicle. The brake drum comprises a braking surface adapted to receive at least one brake shoe of the drum brake. The brake drum further comprises a cooling arrangement comprising a set of cooling conduits located between a braking surface and an outer surface.

The material of the brake drum located radially between the set of cooling conduits and the braking surface at an inner axial cross-section has an inner axial aggregate thermal conductance and the material of the brake drum located radially between the set of cooling conduits and the braking surface at the outer axial cross-section has an outer axial aggregate thermal conductance.

Accordingly, the inner axial aggregate thermal conductance is different from the outer axial aggregate thermal conductance.

A brake rotor includes a friction portion, a hat portion axially extending from the friction portion and including a top face that is axially displaced from the friction portion and a side wall that extends from the friction portion to the top face, and a nose portion which extends axially from the top face of the hat portion away from the friction portion.

A system for cooling the brakes of a brake system of a landing gear of an aircraft, including: a compressor configured to generate a pressurized airflow, the compressor including at least one air outlet, and an air jet pump including: a pump tube including a first end connected to the air outlet and a second end, the pump tube being designed to carry the pressurized airflow between the first and second ends, and a plurality of injectors connected to the second end of the pump tube, and configured to inject the pressurized airflow.

A brake disc (1) including at least one friction ring (2) and a brake hub (3) connected to the friction ring (2) for conjoint rotation. A side wall section (17) of the brake hub (3) has a plurality of radially oriented deformations (5). A contact surface (7) extending in the radial direction is formed by these deformations (5), and a rotationally fixed connection (8) is established by the contact surface (7) between the friction ring (2) and the brake hub (3). A ratio Da/Di formed from the outer diameter Da of a side wall section (17) of the brake hub (3) and an inner diameter Di of the friction ring (2) is at most 1.01.

Brake calipers and rotors for bicycles are described herein. An example brake caliper includes an outboard caliper portion to be disposed inboard of a frame of the bicycle. The outboard caliper portion includes an outboard caliper body and an outboard brake pad that is fixed relative to the outboard caliper body. The brake caliper also includes an inboard caliper portion coupled to the outboard caliper body. The inboard caliper portion is disposed inboard of the outboard caliper portion when the brake caliper is coupled to the bicycle. The inboard caliper portion includes an inboard caliper body and an inboard brake pad that is movable relative to the inboard caliper body.

Brake rotors for bicycles are described herein. An example brake rotor for a bicycle includes a carrier to be coupled to a hub of the bicycle. The brake rotor also includes a brake track having braking surfaces to be engaged by brake pads. The brake track is disposed radially outward of the carrier. The brake track has a first thickness and the carrier has a second thickness greater than the first thickness. The brake track is coupled to the carrier such that the brake track is axially movable relative to the carrier while being radially and circumferentially constrained relative to the carrier.

A disk brake for a motor vehicle includes an internally ventilated brake disk, a brake disk nave, and radially directed bores. In the radially directed first bores the connecting means are introduced such that they extend further into radially directed second bores in the friction ring into the friction ring. The brake disk nave forms the fit with a single friction ring half and this fit has material convexities, which point inward toward the cooling channels or the ribs, at the points at which the second bores are introduced for the connecting means.
