An apparatus (10) that houses functional components of a mechanical assembly includes a frame component (12) formed of a first material, the frame component (12) bearing primary load, torque or pressure applied to the apparatus (10) during operation of said mechanical assembly. The housing apparatus (10) further includes a composite reinforcement component (130) for resisting forces applied to the apparatus during operation of the mechanical assembly and an enclosure component (80) formed of a second material of lower density than the first material of the frame component (12), the enclosure component (80) covering and sealing at least the functional components of the mechanical assembly from external conditions during operation of the mechanical assembly.

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.

Method for producing a compound, rotationally symmetrical component (3) with internal and external teeth consisting of a blank (1) and a toothed body (5), wherein the two parts (1, 5) are designed in the form of a pot and in a first method step are inserted coaxially one inside another with interlocking, mutual support and in a second method step are interlocked together with at least one forming tool (17, 27) applied against the (inner and/or outer) circumference, wherein in the second method step the circumferential surface (14, 14) of said blank (1) is continuously deformed in a rolling forming process in the axial direction and in the radial direction such that the circumferential surface (14, 14) of the blank (1) is deformed to interlock into the tooth bases (10) of the teeth (6) of the toothed body (5).

A method of manufacturing a splined coupler is provided. The method comprising: sintering powdered metal to form a splined coupler; quenching the splined coupler; applying a vacuum pressure across the splined coupler; and migrating oil into the splined coupler using the vacuum pressure.

A flexible coupling includes a first flange and a second flange, wherein in a relaxed state the first flange and the second flange are each aligned along a longitudinal axis. A plurality of first coupling members extends from the first flange. Each first coupling member includes a first and second driving beam meeting at a first node to form a topologically triangular truss. A plurality of second coupling members extend from the second flange. Each second coupling member includes a first and second driven beam extending from the second flange and meeting at a second node to form a topologically triangular truss. The first node of each of the first coupling members is connected to the second node of a respective one of the second coupling members.

A method produces a synchronizer ring for a synchronizing device in which blocking teeth extending radially outwards or radially inwards are produced by a forging method. The blocking teeth each have a flank portion and two oblique top flanks merging into a common top ridge. A depression is formed on the rear side of a blocking tooth opposite the top ridge.

A vehicular brake rotor component made from a Ti base powder alloy which has been 3D printed to a desired shape before one or both of its wear surfaces are coated with a 0.005 to 0.01 inch thick mixture containing about 1-40% chromium carbine. Then the combined product is sintered, machined and double disc ground. Related methods of manufacture of this brake rotor component are also disclosed.

A disc brake rotor has a support hub and coaxial braking band. The support hub has a plurality of radial seats and the braking band has a plurality of connecting elements which transfer torque between the band and the hub. The connecting elements are integral and made as one piece with the braking band and extend from the braking band in order to engage the corresponding radial seats. The connecting elements are surrounded by walls which are integral and made as one piece with the support hub such as to be fastened in the axial direction and in the tangential direction, but capable of sliding in the radial direction.

A method for manufacturing at least one synchronizing ring includes providing a rough-turned blank made from a hardenable material that is in a not-hardened state and laser-cutting the rough-turned blank to form the at least one synchronizing ring, the laser cutting being performed with an energy chosen to be sufficient to selectively harden at least a portion of the material in a region along which the laser cutting occurs.

In some implementations of the current subject matter, a brake rotor can include a supporting layer applied to a friction surface of a brake rotor substrate, which can optionally include cast iron, and a coating applied over the supporting layer. The supporting layer can include a preparatory metal, and the coating can impart wear and corrosion resistant properties to the friction surface. Related systems, methods, articles of manufacture, and the like are disclosed.
