An apparatus configured to be removably attached to a tire/hub assembly of a vehicle via lug nuts of the tire/hub assembly is used to determine imbalance forces of the tire/hub assembly during motion of the vehicle. The apparatus includes a disk and a plurality of cup-shaped objects fixed at one end to the disk and extending perpendicularly outward from the disk. The plurality of cup-shaped objects are arranged a fixed radial distance from a radial center of the disk in a pattern that matches the lug nuts of the tire/hub assembly. The apparatus is mounted to the vehicle's tire/hub assembly by fitting the plurality of cup-shaped objects over the lug nuts of the tire/hub assembly. The apparatus further includes three inertial measurement units (IMU's) mounted to the disk to measure parameters that are used for calculating the imbalance forces during motion of the vehicle. A method for collecting measurement parameters related to imbalance forces of a tire/hub assembly of a vehicle during motion of the vehicle on a road surface by using the apparatus is also described.

Apparatus and method for measuring imbalance forces of a tire/hub assembly of a vehicle during motion of the vehicle

A method is provided for collecting measurement parameters related to imbalance forces of a tire/hub assembly of a vehicle during motion of the vehicle. An apparatus is removably attached to the tire/hub assembly of the vehicle via lug nuts of the tire/hub assembly. The apparatus includes a disk, a plurality of cup-shaped objects, and one or more inertial measurement units (IMU's) mounted to the disk. Each of the cup-shaped objects are rigidly fixed at one end to the disk and extend perpendicularly outward from the disk. The plurality of cup-shaped objects are arranged a fixed radial distance from a radial center of the disk in a pattern that matches the lug nuts of the tire/hub assembly. The one or more inertial measurement units (IMU's) are mounted to the disk and configured to measure parameters that are used for calculating the imbalance forces during motion of the vehicle.
