An apparatus for applying weight material onto a wheel may include a conveyor assembly, upper and lower severing-head assemblies, and upper and lower control arms. The severing-head assemblies may be mounted above and below the conveyor assembly and may include a housing, a severing device and a dispensing mechanism. The dispensing mechanism may position the weight material from a source relative to the severing device. The severing device may separate a predetermined amount of weight material from a source. The control arms may be movably mounted above and below the conveyor assembly and have weight-application tools configured to transfer the predetermined amounts of weight material from the severing-head assemblies to locations on the wheel.

An assembly of a rotating component and a rotationally stationary component includes a first bearing portion located at the rotating component and rotatable therewith, and a second bearing portion located at the rotationally stationary component. The second bearing portion is supported at the rotationally stationary component and rotatably with the rotating component when in contact with the first bearing portion. The first bearing portion and the second bearing portion define a single point contact therebetween.

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 one or more 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.
