MANUAL CONTROLLER WITH CONTROL LEVER

摘要

In a manual controller with a control lever mounted in a housing and held in a bearing so as to swivel around two orthogonal axes around a fixed point, the bearing is designed as an elastomer joint whose elastic restoring force is directed towards the zero position of the control lever from all deflected positions of the control lever. This elastomer joint ensures an accurate bearing and remplaces by a single piece several mechanical components of previous devices. By appropriate dimensioning, additional restoring elements for returning the control lever to its zero position may either be completely dispensed with or have smaller dimensions. In addition, rubber or a corresponding plastic material for the elastomer joint also prevents humidity from entering the housing and thus has an additional sealing function. The elastomer joint, as an easy-to-produce, single-piece component, thus replaces several bearing, restoring and sealing components required in the state-of-the-art, or simplifies their design and production.
