Electromechanical steering system for use in motor car, has ball threaded nut standing in intervention with handlebar and rotatably supported in steering housing by bearing, where bearing is arranged with housing in decoupling manner

摘要

The system (10) has a handlebar (18) extended through a steering housing (20). A gear box converts a drive moment of an electromotor (12) into axial force at the handlebar. The gear box includes a synchronous belt drive that is coupled with a ball threaded nut (32) at an output side, and is coupled with an output shaft of the electromotor at an input side. The ball threaded nut stands in intervention with the handlebar, and is rotatably supported in the steering housing by a bearing. The bearing is arranged with the steering housing in a decoupling manner.
