摘要:
A brake pad assembly is provided, including a friction lining providing a wear surface for contacting a brake rotor and a back plate coupled to the friction lining. The back plate is made of a carbon fiber reinforced carbon matrix composite. In one example, a majority of the carbon fibers of the back plate are oriented in a x-y in-plane direction resulting in a structure where the thermal conductivity is at least 2 times greater in the x-y in-plane direction versus a z through-plane direction. In another example, the back plate is provided as at least one sheet of a carbon fiber reinforced carbon matrix composite. A method of manufacturing the brake pad assembly is also provided.

The present invention is directed to benzoxazine-containing adhesives having high adhesive strength at high temperature. These materials are especially useful in automotive applications, in particular, as adhesives for brake components. Methods of their use are also described.
摘要:
In a method for producing a brake shoe (1), particularly a brake shoe for disk brakes in motor vehicles, by preforming a friction lining (6), arranged on a carrier plate (2), from a friction material fed into a press mould and by press-molding the friction material under pressure and heat to form a friction lining (6), it is provided that grooves (8) are formed in the friction lining (6) which are open at least towards the front face of the friction lining, that the friction lining (6) provided with grooves (8) is exposed to a scorching process, that, subsequent to the scorching process, an elastic filling agent (12) is inserted into the grooves (8), and that, subsequent to the insertion of the filling agent (12), the brake shoe (1) is subjected to a drying process, a hardening process or a cross-linking process depending on the filling agent (12) used.
摘要:
There is provided a method for producing a friction plate, capable of improving the throughput of friction material and reducing the time and work required for adhering friction material segments to a core plate. The method produces a friction plate having oil grooves communicating between the internal periphery and the external periphery, by fixing friction material segments formed from a friction material to a core plate, and is featured by forming the oil grooves by plastic working of the friction material and fixation of the friction material segments with predetermined gaps therebetween to the core plate.

The brake lining (100) for disk brakes comprises a carrier plate (10) and a friction material block (20) fixed thereon made of a pressed friction material, the friction material block (20) being fixed positively and/or nonpositively on the carrier plate (10), the carrier plate (10) being made of a hard amorphous plastic rigid up to the decomposition temperature which is composed of spatially close meshed interlaced macromolecules with a high mechanical strength like for example a duroplastic, the material of the carrier plate (10) gripping into the carrier plate free surface (20a) of the friction material block (20) and overlapping the side walls (21, 22, 23) of the friction material block (20) placed on the carrier plate (10) and being welded with the material of the friction material block (20).
摘要:
A structure of a clutch plate is provided which is capable of retaining its stable quality without any chemical treating agent. In the clutch plate structure, laminar facings (9, 9) are attached to the sides (8, 8) of a metallic core plate (7) with a binding material (10), and a plurality of concaves (11 . . . ) filled with the binding material (10) are formed physically in the sides (8, 8) so that the adhesion area on the side of the core plate (7) becomes larger.
摘要:
A clutch facing (1) having an annular friction material (3) and reinforcing plate (4) integrally connected to the friction material (3) characterized by that the reinforcing plate (4) having substantially the same shrinkage as the friction material has, an annular rib (6) concentrically formed on the connecting surface (5) of the reinforcing plate (4), and radial ribs (7) formed on the connecting surface (5) and crossing the annular rib (6).
摘要:
A fluid operated coupling which includes an inflatable annular tube element of an elastomeric material moves a plurality of aligned friction shoes in a radial direction to effect a torque sustaining clutching or braking engagement. A thermal barrier is provided to retard the transfer of heat from the friction shoes to the annular tube element. The thermal barrier protects the tube element and adds mechanical strength thereto to prevent excessive elongation and extrusion of the tube element between the plurality of friction shoes when the tube element is expanded. The thermal barrier is at least partially imbedded in the exterior surface of the tube element.
摘要:
A brake shoe for a drum brake of the type wherein the lining is attached to a carrier solely by being integrally moulded thereto without the use of rivets or other mechanical fastening device. The carrier is provided with a flat central part and outwardly inclined wings defining a shallow trough in cross-section. The wings have circumferentially spaced radially inward unbroken depressions therein. The concave cross-section of the carrier keys the lining against axial or transverse displacement and the depressions key the lining against arcuate displacement when the lining is applied to the drum.
摘要:
A brake shoe for spot-type disc brakes wherein a backing plate is formed with at least two projections, one extending further than the other, at the opposite lateral edges of the plate to which the friction lining is bonded. As a piston drives the backing plate and lining toward a brake disc, the lining is gradually worn away until the metal of the further extending projection comes into contact with the metal of the disc, thereby providing an audible squeal or warning signal to the vehicle operator while there is still enough brake lining remaining to provide adequate stopping power.
