Abstract
A haptic operating device for a motor vehicle has a base, a stationary central part connected thereto, a rotary knob which can be rotated about the stationary central part and which has a hollow design. A magnetorheological transmission device influences the rotational movement of the rotary knob in a controlled manner. The transmission device has two components which can be rotated relative to each other and one component of which is designed as a brake component that can be rotated relative to the base. The stationary central part is secured to the base by means of a support arm. The transmission device and the support arm are arranged adjacent each other and both are received radially within the rotary knob. The rotary knob is rotationally fixed to the rotatable brake component via a coupling device.
Claims18
A haptic operating device for a motor vehicle, the operating device comprising:
- a base plate, a stationary central part connected to said base plate, and a hollow rotary knob rotatably mounted about said stationary central part, said hollow rotary knob being rotatably mounted about a central rotation axis;
- a magnetorheological transfer apparatus for targeted influencing of a rotational movement of said rotary knob, said transfer apparatus having two components that are rotatable relative to one another, a first component being a brake component that is rotatable relative to said base plate about a rotation axis that is parallel to the central rotation axis and radially offset from the central rotation axis;
- said stationary central part being fastened to said base plate by way of a carrier arm and said transfer apparatus and said carrier arm being disposed adjacent to one another and received radially within said rotary knob;
- and
- a coupling device rotationally conjointly coupling said rotary knob to said rotatable brake component.
A haptic operating device for a motor vehicle, the haptic operating device comprising:
- a base plate;
- a stationary central part disposed above said base plate and connected to said base plate by way of a carrier arm;
- a hollow rotary knob rotatably mounted about said stationary central part, said hollow rotary knob having an internal diameter, said hollow rotary knob being rotatably mounted about a central rotation axis;
- a magnetorheological transfer apparatus for selectively braking a rotational movement of said rotary knob, said transfer apparatus having a braking component that is rotatable relative to said base plate about a rotation axis that is parallel to the central rotation axis and radially offset from the central rotation axis;
- a coupling device disposed to couple said rotary knob to said transfer apparatus for conjoint rotation;
- said transfer apparatus having an external diameter that is smaller than said internal diameter of said hollow rotary knob;
- and
- said carrier arm and said transfer apparatus being disposed next to one another inside said hollow rotary knob.
