A brake disk, the main body of which has been produced from gray cast iron, is coated on its annular brake surfaces with a metallic coating by way of laser deposition welding. In the coating, which includes a welding material with an austenitic structure or at least structural components, a state of internal compressive stress is set by plastic deformation which affects the external outer layer thereof and in one form is performed by a rolling tool.

A one piece drum brake spider construction eliminates welds and distortion, at least relative to a typically fabricated spider, and should improve brake performance. The spider includes a main body plate having opposed flat sides, an outer perimeter, and an inner perimeter configured to receive an axle tube. Vibration control structure is preferably formed on at least one of the opposed flat sides of the main body plate, and the brake drum spider additionally includes weight minimizing features. At least the main body plate may be produced by any of a casting technique, a stamping technique, a machining technique, and an additive manufacturing technique. The invention also concerns a process of producing such a brake drum spider.

A hub built-in type constant velocity joint may include a plurality of wheel guide coupling portions to which wheel guides are configured to be coupled, and a hub housing which is formed between the wheel guide coupling portions and in which a discharge portion is formed to be stepped with each of the wheel guide coupling portions and configured to discharge foreign materials to the outside.

A backing plate for a brake pad that helps improve attachment of the friction pad. The backing plate has a multi-layered structure including a locking plate and a reinforcement plate. Locking holes or locking rings in the locking plate create an undercut portion at mold holes in the reinforcement plate to help mechanically lock the friction material of the brake pad. In some embodiments, retention holes and/or locking rails can be provided to help further retain the friction pad by increasing the available surface area for bonding. Additionally, the retention holes and/or locking rails can help decrease the weight of the backing plate by minimizing the overall size of the locking plate.

A brake pad having a backing plate, friction lining, and a surface coating adhered to the friction lining. The surface coating may be formulated to generate a transfer layer on a brake rotor faster than the friction lining alone. The surface coating may be adhered to the friction lining in a predetermined design.

To provide a rotating member that allows formation of protrusions to be dug into an opposite surface with a simple configuration, and that can prevent a direction-dependent reduction of anti-slip effect and provide sufficient slip prevention in the direction of torque as well as in the radial direction, and a method of forming this rotating member. The rotating member has a boss and an anti-slip surface on at least one of both axial end faces of the boss. The anti-slip surface includes a plurality of crater-like depressions each having a peripheral protrusion. At least some of the plurality of crater-like depressions are arranged serially to form a plurality of crater chains.

A method of manufacture for a carbon/carbon part including a method to remove contamination from an intermediate product of the carbon/carbon part and furnace utilizing a gaseous reducing agent hydrogen gas to reduce the contaminates, thereby causing the contaminates to transition to a gaseous state at relatively lower temperatures. A method to remove contamination from an intermediate product of the carbon/carbon part and furnace utilizing hydrogen gas to reduce the contaminates, thereby causing the contaminates to transition to a gaseous state at relatively lower temperatures.

An asbestos-free friction material includes inorganic and/or organic and/or metallic fibers, at least one binder, at least one friction modifier or lubricant, at least one filler or abrasive and a carbonaceous material constituted by a microstructure. The microstructure is in the form of flakes or scales of micrometric planar dimensions and of nanometric thickness consisting of a substantially pure graphene mono- or multilayers, preferably pre-blended with at least part of the organic binder.

An end disk of a multi-disk clutch is described, which has a ring plate, the ring plate having a central opening and at least one axial impression on a front side via which a corresponding projection is formed on the opposite front side.
