Abstract:
A vehicle service or inspection system including a load roller for applying a radial load to a vehicle wheel assembly consisting of a tire mounted to a rim, with at least one sensor for acquiring measurements of acoustical energy generated by the wheel assembly during loaded rotational movement. The vehicle service or inspection system is configured with a programmed processor to evaluate the acquired measurements to provide a measure of tire road noise, identification of tire defects, and/or identification of sources of noise, vibrations, or acoustical energy on the tire surface such as tire flat spots, cupping, bubbles, embedded foreign objects, or other defects. The processor is further configured with software instructions to utilize the acquired measurements to provide a consumer with a figure of merit associated with the acoustics of the tire undergoing testing
Abstract:
Methods and apparatus for utilizing vehicle wheel assembly surface profile data acquired by a vehicle wheel service system from a non-contact imaging sensor and a projected pattern of optically distinct elements on the vehicle wheel assembly surface to identify one or more features of the vehicle wheel assembly, to receive operator input, and to facilitate the placement of imbalance correction weights onto the vehicle wheel assembly surface.
Abstract:
A vehicle wheel service system configured with a load roller assembly to apply a generally radial load to a vehicle wheel assembly during rotation, and which is configured with sensors to obtain one or more measurements of lateral forces associated with the vehicle wheel assembly during the loaded rotation, from which a quantified representation of lateral force for the tire of the vehicle wheel assembly is determined.
