A brake disc for a disc brake having one or more sliding or not sliding discs on a hub or other central part is provided. The brake disc has an outer circumference and an inner circumference with a number of alternating teeth and gaps on the inner circumference. One or more measures are taken to reduce the risk of crack formation. One of the measures is to arrange areas of reduced material thickness at and/or adjacent each tooth. The areas of reduced material thickness may be openings having an axial or radial extent. Other measures include designing the teeth and gaps in an appropriate way and forming the brake disc with different properties at different parts.

Disc brake

The present invention concerns a disc brake having a caliper encircling one or more brake discs. At least one of said brake discs is received sliding on a hub or a part connected to the hub. According to the invention a maximal angle (&#x3b3;) between the rotational axes of the wheel axle and the brake disc is limited by the clearance between the brake disc and adjacent brake pads.

Guidance of a disc brake

The present invention concerns a disc brake having a caliper encircling one or more brake discs. At least one of said brake discs is received sliding on a hub or a part connected to the hub. According to the invention the caliper is to be mounted in a lagging position. In said lagging position at least a portion of the brake pad assemblies is positioned 0&#xb0;-180&#xb0; behind an imaginary point vertically above the centre of a wheel axle, when seen in the normal direction of disc rotation. The invention is intended for brakes, in which the brake pads only act on a restricted part of a full circle.

Positioning of a brake caliper

The present invention concerns a disc brake having one or more sliding or floating brake discs. The discs are received on a hub by means of splines on the discs and hub, respectively. The discs have means to widen the support of each disc on the hub. The means may have the form of one or more rings, pins and/or clips attached to the discs.

Supported disc

The present invention concerns disc brakes and more precisely a brake disc () to central part () interface. The disc brake has a caliper () receiving one or more brake pads () and encircling one or more brake discs (). At least one of the brake discs () is received sliding on a central part () in the form of a hub, a sleeve or the like. Said central part () is received on a wheel axle or the like. The discs () are connected to the central part () in a rotationally interlocked but axially sliding way by means of teeth (), splines or the like. At least contact parts of the teeth () or the like of the at least one disc () and/or the central part () have the form of arcs, seen in the direction of the wheel axis. Said contact parts are the parts of the teeth faces expected to make contact with each other in a released position of the brake.
