A hub configured to rotate about an axis of rotation in the circumferential direction, and having a connection surface and a connection opening, the connection opening configured to at least partially receive a connector, the connection surface configured to contact indirectly and/or directly with a contact surface of a brake disc, where the contact surface does not include connection openings.

A composite brake disk for a vehicle disk brake, including a brake disk pot which is formed from a first material and is connected to a friction ring made of a different material, wherein the pot shell and a circular-cylindrical collar formed on the friction ring overlap in some regions in the radial direction in a connecting region and are penetrated by a plurality of connecting elements oriented substantially orthogonally with respect to the axis of rotation, wherein the composite brake disk is suitable for transmitting high mechanical and thermal loads in all operating states, while being simple to manufacture, and can also be formed with a particularly thin pot base and, for this purpose, enables the collar to engage radially on the outside around the pot shell in the connecting region.

A carrier pot for a brake disc includes a radially inner hub ring portion for fastening to a wheel axle, a radially outer brake disc ring portion for fastening to the brake disc, and at least one electric/electronic functional component. The carrier pot is made from a fiber-plastic composite and the at least one electric/electronic functional component is integrated into the fiber-plastic composite.

A disc assembly has a braking band, a bell and at least one driving element. The bell has at least one driving surface, forming a tangential abutment surface. The bell rests on at least one surface of the braking band or on a plurality of surfaces of the braking band coplanar with one another. The braking band has at least one driving band surface extending along axial and radial directions, forming at least one tangential abutment surface and slidingly rests on the at least one driving band surface. The driving element is selectively movable from a position in which it avoids resting on the bell to a position in which it rests on the bell and constrains the bell to the braking band in axial and circumferential directions, preventing the braking band from being constrained to the bell in radial direction.

A wheel brake arrangement for a wheel of a vehicle, said wheel brake arrangement comprising a wheel hub (102) comprising an outwardly facing gear teeth arrangement (104) arranged in a circumferential direction thereof; and a brake disc (106) comprising an inwardly facing gear teeth arrangement (108) arranged in meshed connection with the outwardly facing gear teeth arrangement of the wheel hub for preventing a relative circumferential movement between the brake disc and the wheel hub, wherein one of the wheel hub and the brake disc comprises a circumferentially arranged groove (110); wherein the wheel brake arrangement further comprises at least one retainer (112) connected between the wheel hub and the brake disc for preventing a relative axial movement between the wheel hub and the brake disc, wherein the at least one retainer is at least partially arranged in the circumferentially arranged groove (110) of one of the wheel hub and the brake disc.

A braking band of a disc for disc brake includes a first plate and a second plate, arranged facing each other so as to form a gap, a plurality of connecting elements and/or spacers having a plurality of connecting fins, each extending between a radially inner peripheral portion and a radially outer peripheral portion of the braking band along a longitudinal fin direction, coinciding with the longitudinal development axis of the connecting fin. Some connecting fins extend along a longitudinal fin direction and comprise an arched stretch having a concavity kept in the same sense along the entire longitudinal extension of the arched stretch, defining ventilation channels. The first plate inner surface has a plurality of first plate protrusions projecting into the gap from the first plate inner surface towards the second plate. The second plate inner surface has a plurality of second plate protrusions projecting into the gap from the second plate inner surface towards the first plate.

A braking band of a disc for disc brake has a first plate and a second plate, a group of connecting fins connecting the first plate and the second plate, defining a module (M) repeated according to a circumferential direction (C-C). The first fin extends along a first longitudinal direction between a radially inner edge and a radially outer edge forming a circumferentially arched first stretch of first fin having a first concavity (R13) kept in the same sense along the entire extension of the first stretch of first fin in the first longitudinal direction, a circumferentially arched second stretch of first fin having a second concavity (R14), a circumferentially arched third stretch of first fin, and a circumferentially arched fourth stretch of first fin. The second fin develops along a second longitudinal direction between the radially inner edge and the radially outer edge. The first fin is shorter than the second fin.

A braking band of a disk brake disk has a first plate and a second plate arranged joined to each other by connecting elements. The first and second plates have first and second plate outer surfaces, opposite portions of the first and second outer surfaces forming opposite braking surfaces. The braking band has a plurality of attachment portions for connecting the braking band to a vehicle hub or a bell. Each attachment portion has a connection seat. The attachment portions are spaced by recesses. Each attachment portion has an attachment portion wall having opposite side wall portions, two bottom wall portions and an inner end wall portion, and opposite first and second attachment portion surfaces. Each recess extends radially beyond the connection seat. Each side wall portion is joined to the adjoining bottom wall portion by a cylindrical bottom arch avoiding edges. Each side wall portion is joined to the adjoining inner end wall portion by a cylindrical end arch avoiding edges. Each first attachment portion surface is coplanar to the first braking surface except for the wear of the first braking surface.

In a brake-disc intermediate product, a corrugated portion is molded using an upper mold and a lower mold. The brake-disc intermediate product is set in a mold, the mold has a slope corresponding to the corrugated portion, and an angular portion formed along the outer circumferential edge of the corrugated portion is in contact with the slope in a state where the brake-disc intermediate product is set in the mold. The angular portion in contact with the slope is deformed by pressing the brake-disc intermediate product in a direction of the mold, to mold a chamfer portion. The slope is formed so that a chamfering angle formed with respect to an inner bottom surface of the mold is larger at a portion in contact with the concave portion than a chamfering angle at a portion in contact with the convex portion.
