Abstract: The invention relates to a device for measuring and detecting brake dust particles that have been removed from the brake (3). Said device can comprise a particle measuring device (8) for measuring the number of brake dust particles. The particle measuring device (8) can measure the size of the brake dust particles. A removal device (6) for removing or receiving brake dust particles is mounted in an exhaust air duct (10) which conducts an air stream away from a housing (11) surrounding the brake (3). A device (7) is used to guide the brake dust particles from the removal device to the particle measuring device (8). A fan system with a fresh air channel (9) and the exhaust air channel (10) is used to guide an air stream over the brake (3). The device can be an integral component of a brake test level.

Abstract: A steering wheel for a motor vehicle, includes a rim skeleton and at least one rim casing surrounding the rim skeleton, wherein the rim skeleton and the at least one rim casing rest upon each other with respective border surfaces, and wherein the border surfaces are displaceable relative to each other in at least one section.

Abstract: The invention relates to an internally ventilated brake disk for disk brakes, in particular for motor vehicles, having two friction disks that are arranged adjacent to one another, that are connected to one another by webs that have an essentially radial, preset curvature, and that form cooling channels between them for cooling air, and that are separated from one another in the peripheral direction. According to the invention, the webs in each case extend along a preset curve section of a web curve that has a preset curvature, with the individual web curves, separated from one another in the peripheral direction and extending between an outer peripheral edge and an inner peripheral edge, have an essentially identical design.

Abstract: The invention relates to a brake mechanism for a vehicle, in particular for a motor vehicle, with a brake disk and a friction lining. As claimed in the invention, the friction lining forms a reservoir for a protective agent, preferably additives, which transfers the protective agent to the brake disk in the course of a frictional connection between the friction lining and the brake disk.
