Abstract
A haptic operating device for vehicles. The device has a rotatable operating part, a magnetic field source, and a magnetorheological braking device for braking a rotational movement of the operating part. The magnetorheological braking device has two braking components which can be rotated relative to one another and one of which is coupled to the rotatable operating part. The second brake component, acting as an outer brake component, surrounds the first brake component that acts as an inner brake component. A closed magnetorheological brake chamber is provided with a magnetorheological medium and is formed between the two brake components and has a peripheral braking gap.
