CLAMP APPLICABLE TO A WHEEL TYRE AND METHOD FOR APPLYING A CLAMP
A clamp (100) applicable to a tyre (P) on a vehicle wheel and comprising a body (10) that includes a plurality of arms (11) extending radially from a central axis (X) and angularly distributed about the central axis (X) and a plurality of sliders (20), each slidably coupled to a respective arm (11) to move radially between a retracted position and an extracted position. The clamp (100) also comprises an manoeuvring member (30) connected to the body (10) and a plurality of connecting levers (40) having a first end that is articulated to the manoeuvring member (30) and a second end (40b) that is articulated to a corresponding slider (20) of the plurality of sliders (20) so that a movement of the manoeuvring member (30) corresponds to a movement of the sliders (20). The clamp (100) also comprises a locking device (50), movable between a locked position and an unlocked position, and a handgrip (60) integral with the manoeuvring member (30) and grippable by a user to directly move the manoeuvring member (30) about the central axis (X).
UNIVERSAL WHEEL-FIXATION FRAME FOR ELECTRONIC ALIGNMENT SENSOR
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.

Vehicle Leveling Device and Method
A vehicle leveling device for ensuring that a vehicle is level for calibration of sensors that are installed on the vehicle is presented. A lifting jack is placed under each of the vehicle's wheels and a mounting clamp is mounted to each wheel. Each mounting clamp has a sizing frame having two ends, a clamping member slidably mounted upon each end of the sizing frame and a pair of pivotally mounted engagement hooks. A support member mounted central to the sizing frame that supports an indicator that allows a level reading to be taken. The lifting jacks may be actuated under each of the vehicle's wheels as needed the ever level indicator reads the same indicating that each wheel is coplanar and the vehicle is level.
Wheel holder
A wheel clamp (2) for fastening to a wheel (1), in particular to a wheel (1) of a motor vehicle, comprises at least two arms (22, 23, 24) which extend outward from a center (28) of the wheel clamp (2) in a radial direction. Each of the arms (22, 23, 24) has at least one movable element (32, 33, 34) which is movable in the radial direction. The wheel clamp (2) comprises a locking member (82) which is designed such that the movable elements (32, 33, 34), by operation of the locking member (82), can be fixed such that the movable elements (32, 33, 34) are no longer movable in the radial direction. The wheel clamp (2) also comprises an unlocking member (84) which is designed such that a fixation of the movable elements (32, 33, 34) can be released by operation of the unlocking member (84).

In Situ Wheel Position Measurement Using Inertial Measurement Units (IMUs)
Disclosed herein are systems and methods for the in-situ determination of vehicle wheel position using an inertial measurement unit (IMU). In one aspect as the wheel is rotating, gyroscope measurements are used to find a slip angle defined between the direction of wheel travel and the direction of vehicle travel, to determine a toe alignment condition for the wheel. System and methods are also presented for using an accelerometer to measure slip angle and camber angle. Using an accelerometer or gyroscope, instantaneous wheel angle measurements can also be made to predict vehicle movement, and aid in autonomous steering and in-situ wheel alignment adjustments.

WHEEL HOLDER
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.
