A coil housing has an inner ring, which is shaped into an annular form and is placed on an inner side of an electromagnetic coil in a radial direction of a rotational axis. A thermal fuse is placed on an inner side of a coil inner peripheral end of the electromagnetic coil in the radial direction, so that the thermal fuse can be placed in such a manner that the thermal fuse does not limit a length of the electromagnetic coil in a direction of the rotational axis by using a radial thickness of the inner ring that is indispensable as a part of a structure of a magnetic circuit. Thus, it is possible to sufficiently limit occurrence of limiting of a size of the electromagnetic coil that is caused by the placement of the thermal fuse.

The invention relates to a device and a method for the thermal treatment of friction linings by means of IR-radiation, characterized in that IR radiators or IR heating fields are used as a source of infrared radiation, said radiators or heating fields generating IR-radiation in the wavelength range of 2260 nm to 3000 nm.

A synchronizer ring (10) for synchronized manual transmissions is manufactured by forming or reshaping a flat material of metal, wherein a conical friction surface (20) is produced, into which axial grooves (24) are incorporated by chipless machining, wherein a tool is axially shifted relative to the friction surface (20) to produce the final friction surface (20). At least the friction surface (20) is vibration-ground and subsequently hardened.

A brake disk includes a circular base body having a circumferential outer brake rim, a friction layer in certain regions on the base body and an adhesion-promoter or functional layer arranged over an entirety of the base body.

A method for manufacturing a clutch body for a synchronizing device of a transmission includes the steps of: a) providing an externally toothed clutch disk, b) providing a counterfriction ring, c) applying a friction lining onto the counterfriction ring, d) establishing a non-releasable connection between the clutch disk and the counterfriction ring, and e) upsetting a portion of the counterfriction ring at least partly provided with the friction lining in radially inwardly facing direction, so that a counterfriction cone is formed, which is provided for cooperation with a friction surface of the synchronizer ring.

The invention relates to a method for producing a wet friction lining wherein an oil is delivered through pores to a device operated using oil. In a method in which oil delivery from the wet lining is adjustable regardless of the production process for the wet friction lining, the pores are formed using a perforation process.

In some examples, the disclosure describes a method including depositing a first layer including a resin and at least one of a carbon fiber or a carbon fiber precursor material on a work surface of a three-dimensional printing system, carbonizing at least the resin of the first layer using a carbonizer attached to the three-dimensional printer to form a first layer of carbon-carbon composite including carbon fibers and carbonized matrix material, depositing an additional layer including a resin and at least one of a carbon fiber or a carbon fiber precursor material of material on the first layer of carbon-carbon composite, and carbonizing at least the resin of the additional layer using the carbonizer to form an additional layer of carbon-carbon composite on the first layer of carbon-carbon composite.

A disk brake piston system having a piston having a metallic outer wall surrounding a central axis, the outer wall being of a material and a thickness which that could be formed by deep drawing; a metallic front wall closing one end of the outer wall, the front wall including a curved area extending toward an interior of the piston, the front wall being of a material and having a thickness that could be formed by deep drawing; and a sleeve positioned at least partially within the piston and configured to interface with an interior side surface of the outer wall such that the sleeve and the piston are restrained from rotating relative to one another around an axis parallel to the central axis, the sleeve comprising a flat or curved internal surface, having a non-circular cross-section, wherein the sleeve comprises a polymeric material.

A disc brake component, includes: a cast-iron bridge having two passage openings, which are connected to one another by a bridge body and are each configured to receive an actuating spindle, wherein a mold parting line delimiting a draft angle is formed at a distance from an outer edge of the bridge body for manufacturing purposes, and the mold parting line runs parallel to a profile of the outer edge associated with the mold parting line of the bridge body.

The invention relates to a process for producing a brake disk for a vehicle, in which a friction layer is arranged at least in certain regions on a base body of the brake disk.
