Measurement device of position of center of gravity of vehicle to be measured on truck scale and truck scale

摘要

As a measurement table (10), an object provided with a flat surface (11) having an area on which all wheels of a vehicle can be mounted at the same time and a front wheel mounting table (12) which is disposed in front of the flat surface (11) and is lifted by a step of a predetermined height is used, a wheel position detector (8) which is capable of detecting a front wheel position and a rear wheel position of a vehicle to be measured is provided, a computation processing device (3) is provided with anterior-posterior displacement calculation means, an inter-axle distance calculation means (21), a vehicle inclination calculation means (22), a front wheel axle load calculation means (23A), a rear wheel axle load calculation means (23B), an anterior-posterior gravity center position calculation means (24), a storage means (32), an anterior-posterior gravity center displacement calculation means (25), and a vehicle gravity center height position calculation means (26), and from a gravity center displacement which is calculated from anterior-posterior gravity center position information calculated on the flat surface (11) and anterior-posterior gravity center position information in the state in which front wheels are mounted on the front wheel mounting table (12) and a vehicle inclination which is calculated by the vehicle inclination calculation means (22), the position of the height of the center of gravity of the vehicle to be measured is calculated.
