Abstract
A steering apparatus includes a user-actuable steering-angle input device with an associated steering shaft, a steering-angle setting device coupled nonmechanically to the steering-angle input device and a reaction torque device which is coupled to the steering shaft. The reaction torque device produces a reaction torque mechanically and has at least one element which can be deflected elastically in a linear manner and is coupled to the mechanism by a driver unit acting axle steering shaft. In certain embodiments, a steering-shaft pinion and a rack which is coupled to the latter serves as a piston rod for at least one piston that can be deflected elastically in a linear manner. The at least one piston is guided in axially moveable fashion in a cylinder and, together with the piston rod, forms the driver unit. Alternatively, the mechanism can contain an eccentric disc which is coupled rotatably to the steering shaft and against the outer circumference of which there rests the end of a piston rod of a piston guided in axially moveable fashion in a cylinder.
