Abstract: A particularly cost-effective electric-motor brake actuator which is useable in a highly flexible manner in respect of structural boundary conditions has an integrally formed cup which is equipped with a permanent magnet assembly and can be equipped with a separately manufactured, electromagnetic rotor assembly. In this manner, the equipment outlay is reduced as is the construction costs.

Abstract: The invention relates to a rail (16a) of a flexible drive, which rail (16a) is intended to guide a drawing means (2). A lubricant which is introduced into the rail (16a) via the lubricant channel (13) brings about a pressure gap (15) which is formed between the inner side of the drawing means (2) and a guide face (9) of the rail (16a). Direct contact of the drawing means with the rail (16a) is suppressed on account of the lubricant which is introduced into the pressure gap (15), which has a friction-reducing effect.

Abstract: In spite of the absence of a pullout fuse block, functional elements comprising simple socket-type connectors come into contact with an external cable in a mechanically and electrically reliable manner, when said cable has a rod-type or sword-type mating connector which engages directly in the connector by means of a radially protruding return baffle, in a sealed manner, through the rear of an opening in the wall of a housing. If, during the plug-in action, an injection-molded skin which first at least partially closes the opening is enlarged or perforated, the breaking edge nestling against the envelope surface of the mating connector in the plug-in direction provides another retraction block with additional sealing and vibration damping.
