The aim of the invention is to provide a running gear with a mount for a brake linkage on a bogie, wherein the mount has a long service life and requires little maintenance. The transmission of shocks and vibrations between the brake linkage and the bogie is reduced, and the bogie and the brake linkage are electrically insulated from each other. A running gear for a rail vehicle including a bogie and a brake linkage is proposed, having at least one bearing element. The brake linkage is mounted on the bogie and/or is connected to the bogie by means of the at least one bearing element, and the at least one bearing element has a plastic and/or consists of a plastic.

A sliding member includes an overlay layer made of a resin on a side of a sliding surface of a bearing alloy layer. When a valley void volume Vvv (μm.sup.3/μm.sup.2) in the sliding surface of the overlay layer is defined as Vv1, Vv1 is in a range of 0.015≤Vv1≤0.200.

A drag link guide assembly for guiding a drag link comprises a slide bushing and a housing enclosing the slide bushing. The housing comprises a socket portion, into which the slide bushing is inserted. The slide bushing comprises a locating area for the drag link having a substantially circular cylindrical periphery with at least one plane torsional locking face. The slide bushing comprises an outward-pointing structure, which interacts with a mating structure that is provided on the internal surface of the housing. A method for producing a drag link guide assembly is furthermore described.

To provide a rotor for electric water pumps in which a sliding bearing formed of a thermoplastic resin composition can be produced at a low cost and has superior low friction and low wear property, and an inner diameter of the sliding bearing is hardly contracted by the insert-molding. A rotor 1 used for electric water pumps has a main body 2 that supports an impeller of the pump, a sliding bearing 3 that rotatably supports a shaft, and a magnet 4 disposed to face a stator. The sliding bearing 3 is an annealing treated body of a polyphenylene sulfide resin composition. The polyphenylene sulfide resin composition contains 5-30 vol % of carbon fiber, 1-20 vol % of polytetrafluoroethylene resin and 1-30 vol % of graphite relative to the whole volume of the polyphenylene sulfide resin composition. The main body 2 is an injection-molded body disposed by insert-molding a thermoplastic resin composition, which is different from the polyphenylene sulfide resin composition, at an outer diameter side of the sliding bearing 3.

A plain bearing for a steering spindle of a steering column for a motor vehicle. The bearing includes an inner ring with an axially continuous bearing opening for slidably receiving the steering spindle. A prestressing element is configured to exert a prestressing force on the inner ring to clamp the inner ring on the steering spindle and thereby to assign a defined, uniform braking torque.
