Abstract
A Mecanum wheel having a first wheel rim () which bears a multiplicity of rollers () which are arranged adjacent to one another in a circumferential direction and which are in each case mounted so as to be rotatable about a roller axis of rotation () arranged at an angle with respect to a first wheel rim axis of rotation (), wherein said Mecanum wheel is characterized by a second wheel rim () which can be driven together with the first wheel rim () by means of a common drive shaft () and which bears a multiplicity of rollers () which are arranged adjacent to one another in a circumferential direction and which are in each case mounted so as to be rotatable about a roller axis of rotation () arranged at an angle with respect to a second wheel rim axis of rotation (), which second wheel rim is connected to the first wheel rim () via damping means () formed so as to permit a limited relative movement of the first and the second rim () relative to one another. It is provided according to the invention that the damping means () are formed so as to permit a damped, limited relative movement between the first and the second wheel rim () in the circumferential direction and/or perpendicular to a Mecanum wheel axis of rotation () and/or perpendicular to the first and/or to the second wheel rim axis of rotation () and/or at a tilt angle relative to one another.
