A disk rotor of a vehicle brake with improved efficiency in cooling the disk rotor by a synergy effect that comes from ensuring velocity of airflow flowing between cooling fins, ensuring surface areas of the cooling fins, and generating turbulent flow by second fins. A plurality of cooling fins each extending radially from an inner peripheral edge to an outer peripheral edge of a disk rotor are provided inside the disk rotor at intervals in the circumferential direction. Each of the plurality of the cooling fins includes a radial fin extending radially and a second fin spaced apart from the radial fin in the radial direction.

A vehicle braking system reduces particulate emissions resulting from wear of the brake pad and rotor during stopping or slowing of a vehicle. The rotor includes at least one friction surface, that has an outer coating of a corrosion and wear-resistant material. This outer coating can optionally include a first layer comprising a crystalline material and a second layer overlaying and contacting the first layer and comprising an amorphous material. The first layer and the second layer can optionally have an inter-layer period of less than 10 nm such that the structure of the outer coating is that of a superlattice. A brake member that includes a friction material is mounted to a caliper on the vehicle with the friction material disposed opposite the at least one friction surface so that the friction material reversibly engages with the outer coating of the corrosion and wear-resistant material when the braking system is operated to stop or slow the vehicle. Contact between the friction material and the outer coating results in substantially reduced conversion of the friction material to dust while producing an improved coefficient of friction relative to standard braking systems. Related systems, apparatus, methods, and/or articles are also described.

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.

Some pin elements may have a substantially circular cross section, forming a circumference-shaped edge. Other pin elements may have a substantially rhomboidal cross section, forming a symmetric rhombus-shaped edge with respect to a radial direction and a circumferential direction orthogonal to this radial direction. Yet other pin elements may have a substantially circular cross section, forming a circumference-shaped edge.

A triboelectric generation apparatus based on a friction brake and a friction brake provide a simple structure with high reliability, a stable circuit, and high energy recovery efficiency. The triboelectric generation apparatus includes two sensing electrodes arranged in a first friction component of the friction brake. When the first friction component is in frictional contact with a second friction component, induced electric charges are generated on the two sensing electrodes. The induced electric charges are different. An electric charge collection circuit is connected to the sensing electrodes and is configured to store the induced electric charges. Storing the induced electric charges allows for the recovery of energy using a simple structure with high reliability.

The invention relates to an axle-mounted brake disk for a rail vehicle, comprising two friction rings which are arranged in parallel and at a distance from each other and are interconnected by a plurality of ribs extending in the direction of the rotational axis of the friction rings, where at least some of the ribs are embodied with different cross-sections from each other, where the cross-sections of a first subset of the ribs, embodied as supporting elements transmitting pressure forces, do not fall below a minimum cross-section, defined by the stability required in relation to the mechanical load during a brake process, and the cross-section of a second subset of the ribs, used to radiate thermal energy, falls below the minimum cross-section.

A brake pad for a disk brake of a vehicle, in particular a rail vehicle, includes a backing plate, to which a plurality of friction units is fastened, each using a securing element supported on the rear side of the backing plate facing away from the friction unit, wherein each friction unit has, on the side of the backing plate facing away from the securing element, a friction element, which is mounted for tilting by means of a spherical-portion-shaped attachment and under the load of a spring supported on the backing plate, is designed in such a way that an annular disk is arranged between the spring and the friction element, at least some regions of said disk lying against the spring and the friction element.
