Abstract
A load cell detects wheel forces and/or moments at tire test stands in the laboratory and on mobile test vehicles based on the piezoelectric measurement principle. The load cell comprises a base plate and a cover plate facing the base plate as well as a plate-shaped quartz sensor, arranged between the plates in a laminar manner. The base plate and cover plate are designed in an elongated shape and include two or more of the plate-shaped quartz sensors there between. The plate-shaped quartz sensors are arranged in an array with respect to the longitudinal orientation of the plates and are preloaded by the plates.
