The rotary axes of the arms are parallel to the plane of the disk and are perpendicular to the radial direction. Each arm is provided with a traction surface (5), which adjoins to the peripheral tire area in a working position and is pressed to the tire middle point in an idle position. Each arm is fastened to the carrier element at two pins by two levers (3,4).</p> |
