    • 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.
    • 测力传感器基于压电测量原理,在实验室和移动测试车辆轮胎测试台上检测车轮力和/或力矩。 测力传感器包括基板和面对基板的盖板以及以层状布置在板之间的板状石英传感器。 基板和盖板设计成细长的形状,并且包括两个或更多个在其间的板状石英传感器。 板状石英传感器相对于板的纵向排列成阵列,并由板预加载。
