An arrangement and method for mounting a brake disc to on axle hub of a vehicle is provided. The arrangement includes wedge-shaped holes at an radially inner region of the brake disc, corresponding wedge-shaped key inserts, a retaining device such as a retaining ring, and mounting devices such as bolts or studs and nuts that pass through the retaining ring and keys to bias the keys against the axle hub. The circumferential sides of the wedge shapes are aligned with radial lines extending from the rotation axis of the axle hub. This arrangement and method provides a simple, robust and easily installed brake disc mounting that minimizes heat transfer between the brake disc and the axle hub and accommodates thermal expansion of the brake disc and the axle hull to minimize thermal ex pans ion-induced stresses to the brake disc.

A brake disc arrangement to be located at an end of an axle of a vehicle driven by au electric motor includes a rotor assembly having multiple rotor assembly pieces joined together with fasteners, as well as an adaptor. The pieces mentioned include rotor sections defining an engagement portion having surfaces to be contacted by friction pads. The rotor assembly also includes an attachment base and an intermediate section, surrounding a rotor assembly axis of rotation, extending along the rotor assembly axis of rotation between the engagement portion and the attachment base. When assembled, the adaptor extends between a wheel hub base and the attachment base of the rotor assembly so that the rotor assembly is securable to the wheel hub. The adaptor defines an internal volume within which a housing for the electric motor and at least a portion of the wheel hub are receivable.

A segmented support element for at least one lining element includes at least two support segments. support segments are not directly, but indirectly connected to one another.

The present disclosure describes brake rotor preforms and brake pads configured to reduce fracturing and failure of brake rotors by distributing the axial force applied during braking across butt joints between abutting segments of preforms and rotors manufactured therefrom. The preforms comprise a spiral annular structure formed about a longitudinal axis from a plurality of carbon fiber precursor tow segments having a partial annular shape. Each segment is asymmetrical when viewed in the longitudinal axis direction and configured so planes defined by the segment's ends are never coplanar with planes extending radially from the longitudinal axis. The brake pads have a partial annular shape and ends adapted to prevent planes defined by the ends from being coplanar during use with a plane extending radially from a brake rotor longitudinal axis.

A disc brake rotor includes a core including a hat-shaped section, an annular inboard mounting surface, and an annular outboard mounting surface axially spaced from the inboard mounting surface and connected to the inboard mounting surface. The hat-shaped section has a central mounting face and a cylindrical shoulder extending from a periphery of the mounting face. The outboard mounting surface has an interior peripheral edge radially spaced from the shoulder, and the inboard mounting surface has an interior peripheral edge engaged to the shoulder. An inboard friction ring includes radially extending first projections secured to the inboard mounting surface. The outboard friction ring includes radially extending second projections secured to the outboard mounting surface. The first projections are angularly aligned with the second projections. The first and second projections extend into the space between the inboard and outboard mounting surfaces and have a gap therebetween.

A bicycle brake disc includes: a disc body, having connecting portions extending from an inner periphery of the disc body, and each connecting portion including a connecting hole, and first connecting elements; a rotor carrier having a center hole and carrier arms formed by extending from the center hole to an outer periphery of the rotor carrier, and each carrier arm having a through hole; each heat dissipation baffle has a first and second end portions, and fitting holes, the first and second end portions of each heat dissipation baffle respectively clamped between two adjacent connecting portions and two adjacent carrier arms, so that the connecting hole, the fitting hole, and the through hole are sequentially aligned; and the first connecting element passing through the holes to fixedly connect the disc body, the heat dissipation baffles, and the rotor carrier.

A friction disk may comprise a friction disk core and a wear liner coupled to the friction disk core. A depression may be formed in a surface of the friction disk core. The wear liner may comprise a protrusion extending from a non-wear surface of the wear liner. The protrusion may be positioned within the depression of the friction disk core.

A shaped material, for example, a disc for disc brakes, and a method for the manufacturing thereof. The shaped material has a plurality of layers of carbon fibers stacked along an overlap axis, each layer being formed by a plurality of radial segments and transverse segments. Each radial segment is adjacent and joined, on both sides, to a transverse segment and each transverse segment is adjacent and joined, on both sides, to a radial segment, forming in each layer an alternation of radial segments and transverse segments.

A braking and/or clamping device for a shaft guided in relation to a basic body, includes an actuating assembly (10) and a shaft-coupling assembly (80). The actuating assembly comprises a split housing (11) which has two bending plates (15, 16) which can bulge elastically in certain regions. The bending plates each have gripper jaws (23, 24) with frictional surfaces (31, 32). A sealed pressure chamber (37), which can be filled with a pressure medium, is situated between the bending plates. Parts of a shaft-coupling assembly project between the clamping zones, said parts establishing and establish the linking to the braked or clamped shaft. When the pressure in the pressure chamber is relieved, the frictional surfaces of the actuating assembly can be applied to the frictional surfaces of the shaft-coupling assembly, thereby providing the braking and/or clamping force.

A reinforcing rib type barbed backing plate of brake pad, comprising a main body, wherein the upper surface of the main body is provided with inclined upward barbs connected with friction material, and the inclination of the barbs is less than 90. The inner side of the root of the barbs inclines and extends downwards to form grooves lower than the upper surface, and the bottom of the groove inclines upward in the opposite side of the barbs for transition to intersect with the upper surface. The Invention can effectively increase the strength of the backing plate of brake pad, adhesion of friction material and brake performance of the brake pad.
