A torsion bushing includes a body portion defining a torsion rod-receiving bore, one or more helical flexion ribs defining at least a portion of the torsion rod-receiving bore, and a helical lubrication reservoir adjacent to the one or more helical flexion ribs. The torsion bushing may be included in a torsion busing assembly that further includes a bracket. The bracket may have a saddle to receive the torsion bushing, and one or more flanges for coupling the bracket to a frame. The torsion bushing may be included in a torsion rod assembly that further includes the bracket and a torsion rod.

A sliding member includes a resin overlay layer on a sliding-surface side of a bearing alloy layer. The resin layer includes a resin binder and 20% by volume or more of solid lubricant particles with an anisotropic shape dispersed in the resin binder. The sliding surface is located at 0° and has a virtual axis perpendicular to the sliding surface at 90°. An angle θ is formed by a straight line and a major axis of the particles. The total number of the particles in a observation region is N. A rate R1=N1/N of the number N1 of first particles at the angle θ of 70°≤θ≤90° from among the particles is 3%≤R1≤20%, and a rate R2=N2/N of the number N2 of second particles with the angle θ being θ≤20° is 35%≤R2≤65%.

Wear detection in a plain bearing is proposed, with a first component comprising at least one sliding element of plastics material, which has a sliding surface for mobile guidance of a second component relative to the first component. The first component, in particular the sliding element, has a device for detecting wear in a critical region of the sliding element, in particular at the sliding surface thereof, with a transponder and with a detector element which cooperates with the transponder and is arranged on the sliding element. The detector element changes the behavior of the transponder when a predetermined degree of wear is reached in the critical region of the plastics sliding element, such that the wear-induced change is wirelessly detectable. The system and detection method are particularly advantageous for plain bearings for a lubricant-free bearing arrangement.
