A pad for disc brakes, a method for the manufacturing thereof, and a braking system with the pad are disclosed. The pad for disc brakes has a thickness y and a first surface cooperating with actuating means of a disc brake. The pad also has a second tribologically active friction surface that cooperates with the disc of the disc brake. The pad also has a first portion and a second portion, where the first portion of the pad extends for a thickness y.sub.1 from the first surface, and the second portion of the pad extends for a thickness y.sub.2 from the second tribologically active friction surface. The first surface and the first portion of the pad are made of carboceramic material, while the second surface and the second portion of the pad are made of carbonaceous material C/C.

The invention relates to a wet-running multi-plate clutch (1) comprising a number of inner plates (2) and a number of outer plates (3), and a first friction lining (6) is disposed on either side of every inner plate (2) respectively and a second friction lining (8) is disposed on either side of every outer plate (3) respectively, and the first friction linings (6) are located entirely underneath the second friction linings (8) in the radial direction so that the first friction linings (6) move into frictional contact with the outer plate main bodies (7) when the multi-plate clutch (1) is engaged and the second friction linings (8) move into frictional contact with the inner plate main bodies (5) when the multi-plate clutch (1) is engaged. The first friction linings (6) respectively have at least one first groove (13) with a groove depth of up to 100% of a friction lining thickness of the first friction linings (6) and the second friction linings (8) have no or respectively have at least one second groove (16) which has a smaller cross-sectional surface area, as viewed in the longitudinal extension of the second grooves (16), than the first grooves (13) as viewed in the same direction.

A clutch-brake device having an actuating disc, a braking disc, a shaft sleeve, a friction disc, a main coupling body, an intermediate disc, and a cutting tool seat. The coupling and dis-coupling between the main coupling body and a flange of the shaft sleeve is achieved by a cooperative motion between the intermediate disc and the adjacent main coupling body and the cutting tool seat. The clutch-brake device can be used for coupling of the engine and cutting blades of a lawn mower or other applications, and is reliable, of high load capability, stable and durable.

A friction material comprises a base and a porous friction generating layer penetrating into and integral with the base. The base presents a bonding surface. The porous friction generating layer presents a friction generating surface facing opposite the bonding surface of the base. The porous friction generating layer comprises fibers and friction adjusting particles, and about 30 to about 95% of a total surface area of the fibers is in contact with the friction adjusting particles. A curable resin is dispersed throughout the porous friction generating layer and the base.

A number of variations may include a product including a single clutch pack having a plurality of clutch plates, and a first friction material on a first plate of the plurality of clutch plates, and a second friction material on a second plate of the plurality of plates, the first friction material being different than the second friction material, and constructed and arranged to provide a tailored combination of torque capacity and response time that would be produced by a clutch pack having solely the first friction material on plates thereof or the second friction material on plates thereof.

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.

A friction material presents a friction generating surface and a bonding surface facing opposite the friction generating surface. The friction material includes an organopolysiloxane resin, a plurality of fibers, and a plurality of friction particles. The organopolysiloxane resin includes siloxy units independently represented by the following formula: (R.sub.1SiO.sub.3/2) and/or (R.sub.2SiO.sub.2/2); wherein each R.sub.1 and R.sub.2 is independently selected from a monovalent hydrocarbon group having from 1 to 20 carbon atoms.

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.
