The invention relates to a brake pad for a disk brake system, comprising a backplate, the backplate being delimited by two opposing lateral surfaces and an edge comprising a leading edge and a trailing edge of the backplate, wherein a friction layer is attached to one of said lateral surfaces. The backplate comprises two hammerheads extending in a plane defined by the backplate, a leading hammerhead of the two hammerheads protruding from an outer end of the leading edge of the backplate and a trailing hammerhead of the two hammerheads protruding from an outer end of the trailing edge of the backplate.

A brake rotor assembly is provided. The brake rotor assembly includes a brake rotor portion formed from a first material. A tone ring formed from a second material is coupled to the brake rotor portion. The tone ring is formed by an additive manufacturing process, a subtractive manufacturing process, or a combination thereof. The brake rotor portion may be cast from an iron or iron alloy. The tone ring is formed by an additive manufacturing, or 3D printing, process machine from a second material that is corrosion resistive, such as, for example, stainless steel.

The present invention relates to a disk (2) for a disk clutch or brake (4) comprising a first friction surface (28) and a second friction surface (34) facing away from the first friction surface (28), in which recesses and/or grooves (40, 42, 44) are provided. A first type of recesses and/or grooves (40), which is generated by a material shaping and/or a material casting and/or a non-material removing first manufacturing method, is provided in the first friction surface (28), and a second type of recesses and/or grooves (42), which is generated by a material removing second manufacturing method, is provided in the second friction surface (34). In addition, the present invention relates to a disk clutch and brake (4) comprising such a disk (2) and a method for producing such a disk (2).

The invention relates to a method for applying sand to the inner radius of drum brake linings comprising the following steps: a) rolling a UV-curing adhesive onto the inner radius of a drum brake lining, b) applying a frictional grain, such as zircon sand, to the adhesive layer, c) removing the frictional grain not retained by the adhesive from the lining surface, and d) curing the coating by means of UV radiation.

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.

A laminated shim for a disc brake includes base and cover shim plates. The base shim plate includes a base side substrate portion, and a base side locking piece extending in a lamination direction of the base shim plate and the cover shim plate. The cover shim plate includes a cover side substrate portion which is laminated on the base side substrate portion, and a cover side locking piece which extends from the cover side substrate portion in an extension direction of the base side locking piece and is radially overlapped with the base side locking piece. A circumferential end portion of one of the base side locking piece and the cover side locking piece abuts against a movement restricting surface facing a circumferential direction and provided at one of the base side substrate portion and the cover side substrate portion.

A method of manufacturing a camshaft for a drum brake includes designing a tubular camshaft and thereafter forming the camshaft as a unitary body through, for example, an additive manufacturing process. The camshaft is designed with a first end portion configured for coupling to a brake actuator, a second end portion defining a cam configured to engage cam followers coupled to first and second brake shoes, rotation of the cam causing the first and second brake shoes to move between positions of engagement and disengagement with an associated braking surface, and an intermediate portion disposed between the first and second end portions. A wall thickness of at least one of the end portions and the intermediate portion is configured to achieve at least one of a predetermined torsional stiffness in the camshaft and vibration damping in the camshaft at a selected frequency.

A spring applied hydraulic released brake includes a brake housing including a pair of stator assemblies, a pair of piston-spring assemblies, each of the piston-spring assemblies including a piston assembly, a spring assembly adapted to apply spring force to the piston assembly to thereby engage the piston assembly with a first stator assembly of the pair of stator assemblies in a default position of the brake, and an end cap adjuster providing an opposing surface against which the spring assembly is biased, the end cap adjuster including a body portion having an end cap threading therearound generally corresponding with a housing threading within the brake housing.

A hydraulic caliper assembly includes a caliper brake housing including two opposing pairs of two piston assemblies, each of the pairs of two piston assemblies adapted to place a respective stator assembly of a pair of stator assemblies in a braking position, where the caliper brake housing is a unitary, cast component having an internal fluid porting system fluidly coupling each of the piston assemblies with a source of hydraulic fluid, and where each of the piston assemblies have a common configuration.

A stator pad assembly includes a backing plate including a plate slot extending to a plate slot end, the backing plate carrying a stator lining including a lining slot extending to a lining slot end, the lining slot being generally positioned with a portion of the plate slot such that the plate slot end and the lining slot end are of similar position, and the plate slot defining a tool-engaging surface adapted to receive a tool to thereby cause the stator pad assembly to travel.
