Disclosed are a method of manufacturing cage for a constant velocity joint and a cage for a constant velocity joint manufactured using the same for providing a cage having improved hardness, strength, and elongation while having a structure with a uniform core part and surface and for ensuring economic feasibility by reducing manufacturing time. The method includes a cutting operation of forming a structure having an outer shape by cutting a cylindrical pipe, forming an outer circumference of the cut structure to have a curved surface thereon, performing a turning operation on a surface of the formed structure, a punching operation of forming a window in the surface of the structure on which the turning operation is performed, a broaching operation of processing an edge of the window formed via punching, and a heat treatment operation of fully hardening the completely broached cage via austempering.

A brake disc having a friction ring and a hub produced as a separate element and arranged inside the friction ring according. Recesses are configured in the friction ring on the inside to connect the hub to the friction ring and corresponding projections are formed on the hub, which projections engage in the recesses of the friction ring in order to be able to transfer torque from the friction ring to the hub. The recesses have an undercut at least partially in a radial direction, as viewed looking inward from the outside. The disc is simple and cost-effective to manufacture and has an acoustically advantageous operating performance, in particular in the case of thermal expansion.

There are provided a method of manufacturing an aluminum product and a method of manufacturing an aluminum brake caliper each using die casting, for improving flow and run of molten metal during casting and enhancing productivity and quality. In a method of manufacturing an aluminum product provided with opposing portions opposed to each other with a hollow portion interposed in between, and connecting portions connecting the opposing portions at two sides thereof, the method includes a die casting step of performing casting by pouring molten metal of an aluminum alloy from a gate for the molten metal formed in one of the opposing portions via the connecting portions and a bridge connecting the two opposing portions, and a bridge removing step of removing the bridge.

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.

The present invention relates to a disk clutch comprising a first disk set (32) which is connected rotationally fixed to a first disk carrier (18) and a second disk set (42) which is connected rotationally fixed to a second disk carrier (24), wherein the disks (34 through 40, 46 through 52) of the two disk sets (32, 42) may be brought into frictional engagement with one another via friction surfaces (54, 56), wherein recesses and/or grooves are provided in at least one or more friction surfaces (54, 56) of the disks (34 through 40; 46 through 52) of the first and/or second disk sets (32; 42). A first type of recesses and/or grooves (68) is thereby provided, which is generated by a material shaping and/or a material casting and/or a non-material removing first manufacturing method, and a second type of recesses and/or grooves (70) is provided, which is generated by a material removing second manufacturing method. In addition, the present invention relates to a disk (66) for such a disk clutch and a method for producing such a disk clutch (2) and such a disk (60).

A brake shoe for a drum brake includes a unitary body defining a brake table and one or more webs supporting the brake table. Each web has first and second ends. The first end is configured for pivotally coupling to an associated brake spider of the drum brake and the second end is configured to respond to a force applied by an actuator that causes the brake shoe to move between positions of engagement and disengagement with an associated braking surface. The unitary body further defines one or more supports extending between the two webs and/or between one of the webs and the brake table. In some embodiments, the supports comprise vibration dampers configured to deflect from an unloaded position to a loaded position in the presence of a load and to return to the unloaded position in the absence of the load.

A length-adjustable steering shaft for a motor vehicle may include a hollow outer shaft with an unround inner cross section, in which an inner shaft is received in a torque-locked and axially movable manner. A profiled sleeve may be arranged between the inner shaft and the outer shaft, and the profiled sleeve may have a fastening portion connected to the inner shaft. The inner shaft may be configured at least in part as a hollow shaft that has an interior that is open towards the end that is inserted into the outer shaft. To reduce the outlay in terms of production and assembly, the fastening portion may extend from the end into the interior of the inner shaft and is connected to an inner surface of the interior.
