A method of manufacturing a brake pad including a friction pad and a mounting structure includes providing a cure mold; filling the cure mold with granulated thermoset plastic to form the mounting structure and particulate friction material to form the friction pad; and press curing in a single step the filled cure mold to form the brake pad.

The present disclosure provides a fibrous preform, comprising an annulus having at least one of an outer diameter portion or an inner diameter portion, the outer diameter portion extending radially inward from an outer diameter of the fibrous preform and the inner diameter portion extending radially outward from an inner diameter of the fibrous preform. In various embodiments, the fibrous preform further comprises a medial diameter portion disposed between the outer diameter and the inner diameter, wherein the medial diameter portion comprises a first needling profile, and the at least one of the outer diameter portion or the inner diameter portion comprises a second needling profile. In various embodiments, the first needling profile is less than the second needling profile.

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.

A sliding sleeve for a synchronous manual transmission assembly is produced by the following steps: a tubular blank is provided in which an internal toothing arrangement is present, and the blank which is provided with the internal toothing arrangement is further processed to form a plurality of sliding sleeves.

A method for producing a molded body of particularly steel, and including a hub and a bell-shaped lower part axially connected thereto, in which an inner contour is made in the lower part by non-cutting forming in a convex region. The inner contour includes of ball tracks and cage paths that are concave in the axial direction and arranged in a peripherally alternating manner, for receiving rolling bodies, the cage paths being shallower than the ball tracks. The hub is formed from a rotating round blank and reducing the thickness thereof using at least one pressure roller. The flat region of the round blank that radially connects to the hub is pressed onto contour segments of a rotating first inner contour tool, partially forming the inner contour using at least one axially and radially moving pressure roller to form a preform of the lower part. The fixed preform is pressed against contour segments of a second inner contour tool by a die of partial dies, fully forming the cage paths and ball tracks.

A method of manufacturing an outer joint member of a constant velocity universal includes forming cup and shaft members of medium carbon steel, preparing, as the cup member, a cup member having cylindrical and bottom portions integrally formed by forging, and a joining end surface formed on an outer surface of the bottom portion after the forging, preparing, as the shaft member, a shaft member having a joining end surface to be joined to the bottom portion of the cup member, and bringing the joining end surfaces of the cup and shaft members into abutment against each other. The method also includes welding the cup and shaft members from an outer side of the cup member to an abutment portion between the cup and shaft members in a radial direction of the cup member.

A wet parking brake device includes a shaft case, a rotary shaft, a plurality of stators, a plurality of brake discs, a piston member, and a pressing mechanism. The wet parking brake device is configured such that the brake discs and the stators come in contact with each other by a pressure from the piston member pressed by the pressing mechanism to thereby generate a braking force against the rotary shaft. The pressing mechanism includes a parking rod. The parking rod includes a rod main body, a turning shaft portion, and a connecting shaft. The shaft case includes an opening and a shaft hole. A length of the parking rod, the diameter of the shaft hole and the diameter of the turning shaft portion are respectively designed such that the turning shaft portion is inserted into the shaft hole when the parking rod is inserted from the opening.

An electric linear motion actuator is provided which includes an outer ring member, a rotary shaft, planetary rollers, and a carrier including a disk, and in which the outer ring member is formed with a helical rib, each of the planetary rollers being formed with circumferential grooves in which the helical rib is engaged. When the rotary shaft rotates, the planetary rollers rotate about their axes while revolving around the rotary shaft so that the outer ring member axially linearly moves. The actuator includes thrust roller and retainer assemblies each mounted between one of the planetary roller and the disk of the carrier, and each guided by a raceway, i.e., an end surface of the corresponding planetary roller. The actuator includes a common raceway disk common to all of the thrust roller and retainer assemblies, and mounted between the thrust roller and retainer assemblies and the disk of the carrier.

A brake pad includes a friction material and a backing plate which are coupled to each other. An apparatus for manufacturing the brake pad includes a forming device forming friction material powder in the form of the friction material and attaching the formed friction material to the backing plate in a forming process, a quality stabilization device heating and pressing the friction material, and a heat treatment unit heating the brake pad at a predetermined temperature.

A roller freewheel includes a roll body cage, a plurality of roll bodies accommodated in the roll body cage, and a ramp ring having a ramp contour. The ramp contour blocks the roll bodies in a first direction of rotation and allows rotation of the roll bodies relative to the ramp ring in a second direction of rotation, opposite the first direction of rotation. The ramp contour is designed to accommodate a plurality of roll body rows. The roll body cage includes a plurality of separate partial cages, with each partial cage including at least one roll body row.
