The invention relates to a friction device (1) comprising a cage-like support element (2), wherein the support element (2) comprises a cage casing which is formed from a plurality of a disks (4) which are arranged consecutively in axial direction (5), comprise an annular main disk body (6) and which each have on their outer periphery (7) or inner periphery (14) a plurality of torque transmission elements (8), wherein gaps (10) are formed respectively between the torque transmission elements (8) in peripheral direction (9) of the disks (4), and the torque transmission elements (8) of the respectively adjacent disk (4) engage in the gaps (10) of the disks (4).

A clutch disc assembly, comprising a friction plate, a damper fixedly secured to the friction plate, comprising an inwardly facing saline and a retainer plate, the retainer plate comprises a first radially inwardly facing surface and a second radially inwardly facing surface radially offset from the first radially inwardly facing surface, and a hub, the hub comprises a first radially outwardly facing surface having a circumferential groove, a second radially outwardly facing surface having an outer saline that meshes with the inwardly facing saline to non-rotatably connect the hub and the damper, and an internal saline surface.

A double cardan yoke joint is disclosed. The double cardan yoke joint comprises a housing having an axial direction. The housing includes a top end and a bottom end. The double cardan yoke joint further comprises at least four flanges positioned inwardly with respect to the axial direction of the housing. The two of the at least four flanges are provided on the top end of the housing and remaining two of the at least four flanges are provided on the bottom end of the housing. The housing is a circular housing with a single weld. The single weld is disposed along the axial direction of the housing.

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 disc brake assembly and a method of mounting a disc brake assembly. The disc brake assembly may have a caliper that may receive first and second brake pads, a cover, and a spacer. The cover may have an opening pattern arranged to allow insertion and removal of the spacer.

Fiber for tribological applications, with the exception of mineral fibers, comprising at least one solid lubricant, with the exception of graphite, or boated with at least one solid lubricant, with the exception of graphite.

A water entanglement system having a first rotatable surface comprises a first water jet which may be configured to water-entangle a preform in situ. The water-entanglement system may comprise a second rotatable surface disposed proximate the first rotatable surface. The second rotatable surface may comprise a second water jet configured to water-entangle the preform in situ. The first rotatable surface may be oriented substantially parallel to the second rotatable surface.

A race for a mechanical clutch assembly may be formed from multiple race layers that assembled from pluralities of stamped arcuate segments. First and second race layers may have the same shape when their arcuate segments are assembled are assembled. The arcuate segments of the first race layer may be identical to each other, and the arcuate segments of the second race layer may be identical to each other, but the first layer arcuate segments are not identical to the second layer arcuate segments. Interlocking joints between the first layer arcuate segments are not aligned with interlocking joints between the second layer arcuate segments when the race layers are joined together and aligned for use in the mechanical clutch assembly.

A new iron-based powder containing a plurality of composite particles composed of a ferritic iron or iron-based porous 5 structural particles having at least one particulate friction modifier distributed in the pores and cavities of the structural particles and further containing at least one particulate stabilizer-sealer. The composite particle is especially suited to be used as a functional material in friction formulations such as brake pads and enable replacement of copper or copper-based materials used in such friction 10 material formulations.

Disclosed herein are pistons for transferring a force perpendicular to a length of a cylinder in which the piston is arranged. The pistons may include an outer structure including a piston face configured to transfer the force, a piston wall configured to align parallel with and proximate to a cylinder wall of the cylinder, and the piston face and piston wall defining an internal volume of the piston. Further, the pistons may also include a inner structure. The outer and inner structures can bound hollow spaces within the piston. The inner structure can also include a discharge hole or a pair of intersecting crossing members.
