A centrifugal clutch (1) for a drive train of a motor vehicle, has an input component (2) which serves for the introduction of torque, an output component (3) which serves for the discharge of torque, and a switchable friction unit (4) which is arranged between the input component (2) and the output component (3) and connects the input component (2) to the output component (3) in a torque-transmitting manner by way of a frictionally-locking connection. The clutch includes an engine-side centrifugal mass (5) and a transmission-side centrifugal mass (6) for actuating the friction unit (4), which centrifugal masses (5; 6) are operatively connected to an engine-side and transmission-side bent sheet metal piece (7, 8) in such a way that a radial displacement of at least one of the centrifugal masses (5; 6) forces an axial displacement of the respective bent sheet metal piece (7; 8). At least one of the centrifugal masses (5; 6) has a cut-out (9) which is such that at least one device (10) which is fixed to the input component has an arm (11) which engages into the cut-out (9) in such a way that guidance of the radial displacement of at least one of the centrifugal masses (5; 6) is ensured.

A laminated shim for a disc brake includes base and cover shim plates. The base shim plate includes a base side substrate portion, and a base side locking piece extending in a lamination direction of the base shim plate and the cover shim plate. The cover shim plate includes a cover side substrate portion which is laminated on the base side substrate portion, and a cover side locking piece which extends from the cover side substrate portion in an extension direction of the base side locking piece and is radially overlapped with the base side locking piece. A circumferential end portion of one of the base side locking piece and the cover side locking piece abuts against a movement restricting surface facing a circumferential direction and provided at one of the base side substrate portion and the cover side substrate portion.

A method for producing a joint outer part by means of flow forming is provided. A blank is arranged on a contour mandrel such that it cannot rotate with respect to the contour mandrel. The contour mandrel is driven in such a way that the blank and the contour mandrel rotate about a common axis. The blank is shaped at least partially with the aid of a flow forming roller which acts on the blank in order to form the joint outer part. At least one track is formed with a concave region in the joint outer part.

Provided are a disc brake and a piston whose weights can be effectively reduced. A disc brake includes a piston configured to press a pad against a disc. The piston includes a body member formed into a bottomed cylindrical shape and including a cylinder portion and a bottom portion. The cylinder portion and the bottom portion are approximately equal in wall thickness. The piston further includes a plate-shaped member fixed to an external bottom surface of the body member and disposed within a range of the external bottom surface and in a region including a center of the external bottom surface.

A brake component mounting structure for a thin-wall axle of a heavy-duty vehicle including a mounting plate and a brake component bracket. The brake component bracket is attached to and extends from the mounting plate. The mounting plate has at least one continuous edge attached by a continuous weld to the axle.

A synchronizer ring for a synchronization unit has a substantially constant sheet-metal cone which tapers in direction of its ring axis from a first axial cone end towards a second axial cone end. At the sheet-metal cone a centering collar is integrally molded and the sheet-metal cone includes a first sheet portion and axially adjacent a second sheet portion. In addition, the sheet-metal cone includes a step portion which axially extends between the second axial cone end and the first sheet portion, wherein a radial outer side of the step portion is offset with respect to a radial outer side of the first sheet portion towards the ring axis. Furthermore, there is shown a method for manufacturing a synchronizer ring.

A shoe element for use in a drum brake includes a web segment and a support segment, wherein the support segment includes a spherical segment, the web segment includes a web-side engagement segment for interlocking engagement with a shoe web or is integrally formed with a shoe web, and wherein the web segment and the support segment are integrally formed with one another.

A multiplate clutch or brake has a plate carrying device (2) having a plate carrier (4). The plate carrier (4) has a tubular section (24). The plate carrying device (2) also has a supporting ring (6), which surrounds the tubular section (24) and on which the tubular section (24) can be supported or is supported outwardly in a radial direction (12). A cross section of the supporting ring (6) has at least one radial leg (30; 38) extending substantially in a radial direction (12, 14).

A method for producing an automotive friction material with optimized multi-dimensional construction includes receiving a base friction-disc material, cutting the base friction-disc material to a predetermined size and shape, assembling the sized and shaped cut base friction-disc material, bonding the base friction-disc material to a base friction plate, and utilizing a multi nozzle printing array to deposit friction enhancing materials overtop a reaction surface of the base friction-disc material.
