A brake backing plate includes first and second sheet metal stampings. Each sheet metal stamping has a respective textured face with a plurality of integrally formed piercing members. A solid non-porous metal core is sandwiched between the first sheet metal stamping and the second sheet metal stamping. The piercing members of the first sheet metal stamping penetrate into the metal core, and the piercing members of the second sheet metal stamping penetrate into the metal core, to secure the first sheet metal stamping, the second sheet metal stamping, and the metal core together.

A back-plate composition of the present invention is a composition for forming a back plate of a brake pad, the brake pad having a friction material and the back plate bonded to the friction material. The back-plate composition includes a resin, a plurality of first fibers and a plurality of second fibers having an average length shorter than an average length of the first fibers. In the case where the average length of the first fibers is L1 [m] and the average length of the second fibers is L2 [m], L2/L1 is in the range of 0.001 to 0.5. This makes it possible to provide a back-plate composition having excellent moldability, as well as a back plate formed of the back-plate composition, a brake pad including the back-plate and a caliper device provided with the brake pad.

A brake disc for a motor vehicle is disclosed. The brake disc includes a substrate, in particular a grey cast iron substrate, at least one friction surface formed on the substrate and at least one cover layer applied at least to the at least one friction surface. The cover layer is harder and thinner than the substrate and color changes to enable identification are introduced in the cover layer by a pulsed laser.

A composite driveshaft includes a body having a first end, a second end, and an intermediate portion defining a driveshaft axis (DSA). The first end defines a first coupling region and the second end defines a second coupling region. At least one of the first and second coupling regions defines a virtual hinge configured to accommodate both bending moments and axial changes of the body.

A compensating coupling connects a first shaft to a second shaft along an axis of rotation. The compensating coupling has a first coupling body connected to an end of the first shaft and a second coupling body connected to an end of the second shaft. At least one elastic coupling element has a longitudinal axis lying in a plane that is oriented perpendicularly to the axis of rotation. The two coupling bodies are arranged with respect to one another to form a three-dimensional coupling region in which the elastic coupling element is arranged. The elastic coupling element is connected to the two coupling bodies such that the two coupling bodies are displaceable in the radial direction with respect to the axis of rotation. The elastic coupling element is displaceable in the axial direction with respect to the axis of rotation.

A number of variations may include a product that may include at least one working friction surface that may include at least two layers that may include a compound layer and a nitrogen diffusion layer wherein the compound layer may have a porosity ranging from about 19% to about 50%.

A corrosion and wear-resistant brake disc is disclosed. The brake disc comprises a brake body having at least one braking surface, and a corrosion and wear-resistant coating electrodeposited on the braking surface. The corrosion and wear-resistant coating comprises a precipitation-hardened cobalt-phosphorus (CoP) alloy and exhibits a Vickers hardness of from about 900 to about 1050 HV. A method of preparing the brake disc is also disclosed, and comprises electrodepositing a cobalt-phosphorus (CoP) alloy onto at least one braking surface of a disc body to a thickness of at least about 150 m to give a coated disc body. The method also comprises heat treating the coated disc body to precipitation harden the CoP alloy and give the corrosion and wear-resistant coating on the braking surface.

Disclosed is a brake pad for yaw control comprising: a braking part having a braking surface, and including a fluororesin fiber assembly and a matrix resin infiltrated into the fluororesin fiber assembly.
