WEIGHT MEASURING SYSTEM FOR WHEEL OR AXLE

摘要

PROBLEM TO BE SOLVED: To remove errors that are caused depending on a height difference between a weighing table and a road surface and are changed with time in a weight measuring system for wheel or axle.;SOLUTION: A first weighing scale 4 includes a first weighing table 6 having a larger size than the length of contact surface of tires of a vehicle in the traveling direction of the vehicle, and it measures the weight of vehicle wheels while the contact surfaces of the tires are not in contact with a road surface 2. Second weighing scales 16 and 18 include a second weighing table 24 respectively having a smaller size than the length of contact surface of tires of a vehicle in the traveling direction, and they measure the weight of vehicle wheels while the contact surfaces of the tires are not in contact with the road surface 2. The weighing scales 4, 16 and 18 are arranged along the traveling direction of the vehicle. Based on the comparison results of the weight measured values of the weighing scales 16 and 18 and the weight measured value of the weighing scale 4 when the vehicle passes through the weighing scales 4, 16 and 18, a computation circuit 14 corrects errors specific to the weight measured values of the weighing scales 16 and 18.;COPYRIGHT: (C)2011,JPO&INPIT
