Abstract: An electric linear motion actuator includes planetary rollers mounted between the radially inner surface of an outer ring member and the radially outer surface of a rotary shaft, and a carrier rotatable about the rotary shaft and including radially movable roller shafts rotatably supporting the respective planetary rollers. Elastic rings each having circumferentially separate ends are each wrapped around the roller shafts to radially inwardly bias the roller shafts, thereby bringing the respective planetary rollers into elastic contact with the radially outer surface of the rotary shaft. Each elastic ring is prevented from rotating relative to the roller shafts, thereby preventing one of the roller shafts from being axially aligned with the gap between the circumferential separate ends, causing the elastic ring to be radially compressed and thus making it impossible for the elastic rings to radially bias the roller shafts.

Abstract: A multi-part piston for a brake saddle of a hydraulically and/or mechanically and/or electromechanically actuated disk brake is described herein. The piston is a pot open on one side and including a base and a wall attached thereto in one piece. The base can be impinged by brake pressure coming from the inside of the pot so that an outward-facing abutting surface of the base can be pressed against a brake lining. The inside of the pot receives at least one pressure piece associated with a parking brake mechanism. For simplified manufacture in the form of a modular piston system for use in various applications, it is proposed that the pressure piece and the base comprise conical surfaces facing one another for transferring braking pressure.
