Abstract
The invention concerns a linear actuator for the conversion of a rapid rotational movement with low moment into a slow linear movement with high force. The concept of a special roller drive of planet gears and two ring wheels makes possible purely theoretically infinitely large reductions with relatively high efficiency. As preferred application of this linear actuator device there is suggested an integration in an electric driven brake system for example for automobiles. The inventive linear actuator is realizable with comparatively small constructional expenditure and in very small construction sizes.
