Tyre test stand with a hexapod arrangement

A tire test stand, comprising:

• a frame;
• a tire holder to which a tire with a tread can be attached so as to be rotatable about an axis of rotation;
• a hexapod arrangement with six linear drive elements, each of the six linear drive elements being attached at a first end to the frame and at a second end to the tire holder;
• and
• a rolling surface unit having a rolling surface configured to be moved in relation to the frame,
• wherein when the tire is rotatably attached to the tire holder, the tire can be brought by adjustment of the linear drive elements of the hexapod arrangement into a contact position in which the tread of the tire contacts the rolling surface,
• wherein when the tread and the rolling surface are in contact and the rolling surface is moved in relation to the tire, the tire rolls on the rolling surface;
• wherein, in an initial configuration, a tangential plane running parallel to the axis of rotation on the tread is identical to a tangential plane on the rolling surface, a tangential speed of the tread is the same as a tangential speed of the rolling surface at a contact point between the tread and the rolling surface, and each force acting on the tire can be divided into a lateral force component running in the tangential planes and parallel to the axis of rotation, a tangential force component running in the tangential planes and perpendicular to the lateral force component, and a radial force component running perpendicular to the tangential planes;
• and
• wherein the six linear drive elements are arranged in the initial configuration in such a manner that at least one linear drive element of the six linear drive elements is arranged such that when the at least one linear drive element exerts a force on the tire, a largest force component of said force is oriented in the direction of the lateral force component,
• at least one linear drive element of the six linear drive elements is arranged such that when the at least one linear drive element exerts a force on the tire, a largest force component of said force is oriented in the direction of the tangential force component, and
• at least one linear drive element of the six linear drive elements is arranged such that when the at least one linear drive element exerts a force on the tire, a largest force component of said force is oriented in the direction of the radial force component.
