A method for manufacturing a clutch body for a synchronizing device of a transmission includes the steps of: a) providing an externally toothed clutch disk, b) providing a counterfriction ring, c) applying a friction lining onto the counterfriction ring, d) establishing a non-releasable connection between the clutch disk and the counterfriction ring, and e) upsetting a portion of the counterfriction ring at least partly provided with the friction lining in radially inwardly facing direction, so that a counterfriction cone is formed, which is provided for cooperation with a friction surface of the synchronizer ring.

The present teachings provide a method comprising steps of: forming an integral brake caliper body and support bracket that comprises a caliper body and a support bracket; and separating the caliper body from the support bracket.

A disc brake component, includes: a cast-iron bridge having two passage openings, which are connected to one another by a bridge body and are each configured to receive an actuating spindle, wherein a mold parting line delimiting a draft angle is formed at a distance from an outer edge of the bridge body for manufacturing purposes, and the mold parting line runs parallel to a profile of the outer edge associated with the mold parting line of the bridge body.

A brake disc, and a method of manufacturing the same, yield a brake disc capable of exhibiting low thermal deformation and superior wear resistance and corrosion resistance using a new composition for grey cast iron and through nitriding gas treatment thereof.

A brake element carrier body with a metallic base body is claimed, wherein a surface of the base body is at least partially, preferentially completely, coated with an alloy, wherein the alloy has diffused into the base body in a diffusion zone.

In one aspect, a centering sleeve is disclosed herein that includes a hub defining a central opening extending in an axial direction between a first axial end and a second axial end. At least one of the first axial end or the second axial end includes a plurality of fluid grooves on an axially outer surface. Both the first axial end and the second axial end can include the plurality of fluid grooves.

A brake pad assembly for a bicycle includes a spreader spring, and a pair of friction pads. The spreader spring has a first leaf, a second leaf, and a spring joint joining the first leaf and the second leaf together. The spreader spring is biased towards a spread position in which the first leaf and second leaf are spaced apart from each other, and is moveable to a compressed position in which the first leaf and the second leaf are moved towards each other relative to the spread position. Each leaf has a rotor facing surface, and each leaf has a set of grooves gouged into the rotor facing surface to yield a corresponding set of barbs extending from the rotor facing surface. The friction pads are secured to the rotor facing surfaces via the barbs, which are embedded in friction pads.

A method of manufacturing a brake rotor or brake drum having a composite structure includes casting an aluminum alloy to form a core of the brake rotor or brake drum, the core defining a core surface, depositing a high entropy alloy or yttrium stabilized zirconia on the core surface to form a thermal barrier layer on the core surface, and depositing an iron-aluminum-silicon-zirconium alloy on the thermal barrier layer to form a wear-resistant layer on the thermal barrier layer, the wear-resistant layer defining a friction surface of the brake rotor or brake drum.

A brake rotor for a motor vehicle having a composite structure may include an annular body defining opposite friction surfaces of the brake rotor. The annular body may include a core made of a lightweight, magnesium-based alloy; a thermal barrier layer made of a thermally insulating material disposed on the core; and a wear-resistant layer made of an AlFeSiZr alloy of aluminum (Al)+iron (Fe)+silicon (Si)+zirconium (Zr) that is disposed on the core over the thermal barrier layer. The wear-resistant layer may define a first one of the opposite friction surfaces of the annular body.

A clutch device includes a pressure plate movable toward or away from a clutch center and rotatable with respect to the clutch center. The pressure plate includes a flange extending radially outward from an outer circumferential edge of a body, pressure-side fitting teeth projecting in a first direction from a front surface of the flange, holding input-side rotating plates and output-side rotating plates, and being arranged in a circumferential direction, and a flange-side recessed portion recessed in the first direction from a back surface of the flange. As seen in an axial direction of an output shaft, the flange-side recessed portion at least partially overlaps one of the pressure-side fitting teeth.
