Development of a verification device for axle (wheel) load scales based on the automatic loading

Abstract During the verification process of special axle (wheel) load scales for motor vehicles test using standard dynamometer method, it is necessary to first apply pressure vertically receptor through axis force sensor, which a prerequisite subsequent parameter work such as indication error. Aiming at problem low automation in lifting and lowering sensors jacks, this paper introduces device based on automatic loading function proposes specific methods steps. According experimental data after implementation, has advantages high efficiency, can replace existing jack achieve sensor. With its measurement meet requirements JJG1014-2019 “Special Axle (Wheel) Load Scales Motor Vehicle Test”.
