A wheel holder for fastening to a wheel comprises at least two arms extending outward from a base plate of the wheel holder radially; each of the arms having at least one movable element that is movable radially; a central rotation element that is arranged in the center of the wheel holder such that it can rotate; and at least two coupling elements each extending between one of the movable elements and the central rotation element such that the movable elements are movable radially by rotation of the rotation element. The rotation element is attached to the base plate of the wheel holder via a freewheeling system. The freewheeling system has at least one operating state in which the rotation element is rotatable in a freewheeling direction and rotation of the rotation element in a blocking direction opposite to the freewheeling direction is blocked.

This invention improves the process of using automotive wheel alignment toe plates to perform wheel alignment by measuring from the wheel of the vehicle instead of the tire as is standard with toe plates measurement. The result of this new invention is the elimination of the tire as a source of error.

A skate blade sharpening system retains a skate blade in a sharpening position whose centerline has a first location relative to a first visual reference feature. A motor-driven rotating shaft has a wheel-mounting location for mounting a grinding wheel for sharpening operation. The shaft accepts an alignment wheel at the wheel-mounting location during an alignment, the alignment wheel having a second visual reference feature having a second location relative to a centerline of the grinding wheel when occupying the wheel-mounting location. An adjustment mechanism moves the shaft transversely during alignment to vary relative position between the wheel-mounting location and the sharpening position including an aligned position in which the centerline of the grinding wheel is aligned with the centerline of the sharpening position, the aligned position being indicated by alignment of the first visual reference feature with the second visual reference feature during alignment.

The present disclosure relates to a device for detecting and identifying play and checking the attachment of wheel, steering-assembly and suspension parts of vehicles. The device includes a linearly displaceable carriage and a supporting plate which is configured to support a wheel of a vehicle. The supporting plate is rotatable, and the carriage is displaceable with respect to the supporting plate in a direction corresponding to the transverse direction of the vehicle. Additionally, the carriage includes a rotatable structure which is configured to rotate the supporting plate about an axis of rotation.

An alignment frame for affixing a sensor configured to measure one or more alignment angles to a wheel of a vehicle can include a pair of arms configured to contact a tire mounted on the wheel to support the alignment frame, a center base configured to receive a first bar, a second bar, and a third bar orthogonally aligned in a linear alignment such that the first bar is at ninety degrees from the horizontal axis defined by the second and the third bar, and a spacer positioned on each of the first, second, and third bars and configured to align the bars with a face of the rim so as to center the center base with respect to the rim of the wheel. The center base can receive a mounting portion of the sensor to center the sensor with the respect to the rim of the wheel.

An alignment gauge for aligning a hub of a vehicle is provided. The alignment gauge includes a first gauge component having a first slot to receive a first hub of the vehicle. The alignment gauge further includes a second gauge component having a second slot to receive a second hub of the vehicle. The second hub and the first hub are separated from each other, via an axle carrier of the vehicle. The alignment gauge further includes a retractable cable component that couples with at least one of the first gauge component or the second gauge component, and span between the first gauge component and the second gauge component, to align at least of the first hub or the second hub of the vehicle.
