Device for maintaining the position of a rotatably or displaceably mounted shaft, particularly an armature shaft () of an electric motor (), wherein a gripping body () is arranged around the shaft (), and said gripping body is impinged upon by a force () in order to form a friction closure between the gripping body () and the surface () of the shaft (), wherein the force () for maintaining the position is provided by an actively actuated control member () that is connected at least to one end () of the gripping body ().

Device for maintaining the position of a rotatably or displaceably mounted shaft

The invention relates to a device for preventing shifting of a vibration-loaded seal retained between two components braced against one another with the aid of clamping means, in particular to prevent shifting of a seal retained between a plug strip and a housing half shell of a motor vehicle clutch control element. This device includes stop faces for the seal, which act in a plane essentially perpendicular to the prestressing direction and which are embodied at least in part on the clamping means.

Device for preventing a vibration-loaded seal from shifting

Device for connecting components with various electrical potentials and subject to vibration

The invention is based on a device for actuating a clutch ( ), in particular for motor-vehicle drives, having an electronically controllable clutch servo unit ( ) that comprises an electric motor ( ) and a reduction actuator gear ( ) having two gear elements arranged coaxially in relation to each other ( and/or and/or ) that are interconnected with each other in terms of propulsion via a thread ( ) and that are displaced axially in relation to each other when they rotate relative to one another, whereby one of the gear elements ( ) is immobilized axially in a housing ( ) of the clutch servo unit, and the actuating motion of the other gear element ( ) is transferred to a throwout bearing ( ) of a clutch disk. It is proposed that the gear element ( ) that is axially displaceable relative to the housing ( ) is interconnected via a longitudinal guide ( ) with a rotor ( ) or a motor shaft ( ) of the electric motor ( ) in a fashion that is torsion-resistant but axially displaceable, and acts on the throwout bearing ( ) via an actuator ( ).
