A wheel holder (1) for clamping attachment to a wheel (9), in particular to a wheel (9) of a motor vehicle, and for attaching a target (5) for vehicle wheel alignment measurement, comprises a base body (10) having a central portion and at least two, in particular three, arms (22, 23, 24) extending radially outwards from the central portion of the base body (10). Each of the arms (22, 23, 24) has a movable element (32a, 33a, 34a) which is movable relative to the base body (10) in the radial direction in order to vary the length of the arm (22, 23, 24) in the radial direction; a pressure element (52, 53, 54), in particular a compression spring, which is arranged and adapted to push the movable element (32a, 33a, 34a) outward in radial direction; and a traction element (62, 63, 63) mechanically coupled to the moveble element (32a, 33a, 34a) and arranged and adapted to pull the movable element (32a, 33a, 34a) inward in radial direction. The wheel holder (1) further comprises a coupling element (60) that mechanically couples the traction elements (62, 63, 63) of the at least two arms (22, 23, 24) to each other.

A wheel measurement system includes a wheel position and orientation system (WPOS) that has a linear sensor configured to connect with a vehicle and extend between a body of the vehicle and a wheel of the vehicle to measure linear motion therebetween while the vehicle is in motion and two or more rotary sensors configured to monitor angular changes at a mounting position of the linear sensor at the body of the vehicle and a mounting position of the linear sensor at the wheel of the vehicle while the vehicle is in motion. The linear motion and the angular changes determine movements of the wheel relative to the body while the vehicle is in motion.

A bracket for wheel alignment control instruments for vehicle wheels includes a central body having a center, an outer face and an opposing parallel inner face facing a wheel; three gripping arms, the ends of which are distal to the center, have grip members and are simultaneously slidingly mounted onto the central body to slide in radial directions, driven by a first drive system and guided by first guide devices between wheel gripping or releasing positions; spacers holding the bracket, parallel to one side of the wheel, which are simultaneously movable in radial directions relative to the center through adjustable abutment positions, the spacers being slidingly mounted onto the central body to slide independent of the arms, driven by a second drive system independent of the first drive system and guided by the first guide devices.

The present invention relates to a method and a device for adjusting the wheel alignment parameters of the wheels of a vehicle, wherein at least one vehicle axle is gripped by one gripping device per wheel axle, near the wheel flanges of the corresponding axle. According to the present invention, the gripping devices are moved by means of controllable drive means in such a way that the wheel alignment parameters of the wheels are adjusted via the orientation of the gripping devices.
