An improved friction part for a frictionally operating device includes friction lining pieces, which are spaced apart from each other by grooves in order to create a friction surface in the form of a circular-ring-shaped disk, especially in respect of suitability for production and/or functionality. In an example embodiment, the friction part has friction lining pieces, which are spaced apart from each other by grooves in order to create a friction surface in the form of a circular-ring-shaped disk, if some or all of the friction lining pieces are in the shape of triangles. The triangular friction lining pieces may be arranged in a plurality of circumferential rows. The grooves between the friction lining pieces may extend as far as a carrier element. Virtually waste-free usage of the linings is thereby possible. A carrier plate can be used as a carrier element, for example.

A brake disc configured to be connected to a vehicle axle and to be squeezed between brake pads, comprising a central disc body (30) having a first and a second side (32, 34), wherein the second side faces in the opposite direction compared to the first side; a first and a second disc plate (36, 38), each disc plate having a wear surface for producing friction when a brake pad is pressed against the wear surface. The disc plates are releasably secured to said first side and second sides, respectively, so as to enable the first and second disc plates to be replaced by other disc plates. A connecting member (64) prevents rotation of the disc plates relative to the central disc body, the connecting member extending from the first disc plate, through a passage (58) in the central disc body, to the second disc plate. Also presented is a vehicle comprising such a brake disc.

A brake disk includes a circular base body having a circumferential outer brake rim, a friction layer in certain regions on the base body and an adhesion-promoter or functional layer arranged over an entirety of the base body.

A method for applying friction lining elements to a friction lining support is provided. The invention is characterized in that friction lining elements are applied simultaneously to opposite sides of the friction lining support.

The invention relates to a process for producing a brake disk for a vehicle, in which a friction layer is arranged at least in certain regions on a base body of the brake disk.

A friction brake body, in particular a brake disc, for a friction brake of a motor vehicle is disclosed. The friction brake body has a main part with at least one wear protection layer on at least one frictional contact region of the main part. The wear protection layer forms a frictional contact surface on the wear protection layer face facing away from the main part. The degree of hardness of the wear protection layer increases incrementally or continuously from the main part to the frictional contact surface.

A friction part for a frictionally working device includes a plurality of friction lining elements arranged to form a circular disk-shaped friction surface having radial slots disposed between the friction lining elements. The radial slots are arranged to receive a coolant or lubricant traversing from a radial inside of the friction surface to a radial outside of the friction surface. The conformation of the friction lining elements and the arrangement of the friction lining elements relative to one another are optimized with regard to an interdependency between a drawing-in of air and a separation behavior of the frictionally working device, and drag losses. The radial slots may extend in a diffuser-like manner from the radial inside to the radial outside, or the radial slots may narrow in a nozzle-like manner from the radial inside to the radial outside.
