A brake rotor comprising a brake pad wear surface; a hat surface; and a decorative insert comprising an insert material, the decorative insert disposed on the brake pad wear surface, the hat surface, or both; wherein at least one of a friction coefficient between the decorative insert and a brake pad is substantially the same as a friction coefficient between the brake pad wear surface and the brake pad, a wear rate of the decorative insert is substantially the same as or greater than a wear rate of the brake pad wear surface, or a wear rate of the decorative insert is substantially the same as or greater than a wear rate of the hat surface; and at least a portion of the decorative insert is visible on the brake pad wear surface, the hat surface, or both.

An exemplary method for making a metal matrix composite vented brake rotor includes: providing a first side plate; providing a second side plate; and welding the first and second side plates together. The first and second side plates have outer surfaces, inner surfaces, and metal matrix composite portions extending from the outer surfaces to a distance from the inner surface that is less than a thickness measured between the inner surface and outer surface. The inner surface of the first side plate includes a vent portion. The step of welding includes welding the first vent portion to the second inner surface to form the vented brake rotor, the vented brake rotor having a plurality of vents formed by the first and second inner surfaces and the first vent portion.

A pressure plate for a friction coupling such as a clutch or brake system includes one or more pockets with a phase change material disposed therein. The phase change material operates to absorb and release heat when the friction coupling cycles between activation and deactivation so as to minimize a maximum temperature of the pressure plate.

Method and plant for manufacturing braking elements such as vehicle brake pads. The plant can comprise a first station that applies an adhesive to a first face of a metallic element; a second station that applies to the first face of the metallic element a block of friction material; a checking station that verifies the presence of the adhesive by detecting the gray level of a plurality of points of at least one zone of the first face; and a processing unit that compares the gray level detected for each point with a first threshold value, counts the number of points that have a gray level that satisfies a relationship (which is a function of the threshold value) and compares such a value with a second threshold value to discard those metallic elements for which the percentage calculated does not correspond to the second threshold value.

The invention relates to a seal assembly for a brake piston of a vehicle wheel brake, the brake piston being displaceably received in a housing and the seal assembly being configured to fluidically seal the brake piston with respect to the housing; the seal assembly comprising: an elastically deformable seal member having a first portion that is configured to contact an outer surface of the brake piston; a stiffening member arranged at least a second portion of the seal member.

The invention also relates to brake piston assembly comprising such a seal assembly.

The present disclosure describes a brake system for a track section of a linear motor system. The brake system includes a housing receiving a brake flag of a mover and a first brake pad disposed within the housing and having a first tapered surface. The brake system also includes a second brake pad disposed within the housing and having a second tapered surface and a wedge disposed within the housing and comprising a third tapered surface. The brake system also includes an actuator that moves the wedge, wherein movement of the activation wedge causes the first brake pad to move and causes the second brake pad to move.

The present disclosure relates to mechanical braking mechanisms used in electric motor applications. The present braking mechanisms may be configured as non-back-drivable mechanical brakes and provide immediate braking of the motors. According to one embodiment, a mechanical brake assembly for an electric motor may include a female disk having a curved groove and an abutment. The mechanical brake assembly further includes a male disk having a projection, the male disk being attached to a rotor of the electric motor. When the electric motor is energized, the projection of the male disk is allowed to rotate uninterrupted with the rotation of the rotor. However, when the electric motor is de-energized, the projection of the male disk travels within the curved groove of the female disk and abuts the abutment of the female disk, thereby stopping the rotation of the rotor of the electric motor.

A brake pad assembly having a consolidated lining comprised of an enhancement framework disposed within a tribological lining, the enhancement framework and tribological lining having substantially the same compressibility factor. The enhancement framework or tribological lining may advantageously be manufactured using an additive manufacturing technique.

A reinforcement for a hub ratchet base comprising a chain-ring and a ratchet ring. The chain-ring is made of an aluminum material having a chain-ring socket and an assembly shaft. The ratchet ring is made of a metal material with high hardness which can be the titanium alloy material or the chrome-molybdenum steel material. The ratchet ring has an engaging slot corresponding to the assembly shaft of the chain-ring. There are at least three connecting slots disposed on the ratchet ring for accepting at least three ratchet members and at least three corresponding elastic members. Each of the connecting slots of the ratchet ring has a pivoting portion on an end for engaging with a ratchet member and an engaging portion on another end for engaging with an elastic member such that the elastic member pushes against a bottom portion of the ratchet member.

A disc brake is proposed having a brake calliper (1) which reaches over a brake disc (2) and brake linings (3) which are arranged on the two sides thereof and are composed in each case of a friction lining (4) and a rear plate (5), and having a hold-down (7) which runs transversely over the brake linings (3) and is supported against the brake linings towards the disc brake axis (A). The circumferential contour of the rear plate (5) of at least one of the brake linings is defined by an upper edge (21), a lower edge (22) and two side edges (23A, 23B) which extend between the upper and the lower edge. The circumferential contour of the friction lining (4) is also defined by an upper edge (31), a lower edge and two side edges which extend between the upper and the lower edge. In order to make a contribution to the solution of the problem of the structural tightness between the components of the disc brake and the vehicle wheel which rotates around the brake, the main course of the upper edges (21 and 31) of the rear plate (5) and the friction lining (4) where the hold-down (7) runs over the brake lining (3) is interrupted by a recessed portion (25 and 35) of the upper edge (21 and 31) in the direction of the brake disc axis (A).
