PURPOSE:To promote the accuracy of detection of puncture, by using load cells to find out the ground contact load upon the rubber tires of a vehicle, memorizing and processing the maximum load upon each wheel and the time of presence of the load and comparing the processed values with judgment references to detect the puncture. CONSTITUTION:Load cells 6R, 6L are provided between a track 4 for a vehicle 1 and tread boards 5R, 5L. When wheels 3A-3D pass the load cells 6R, 6L, the load of each wheel and the time of presence of the tires on the tread boards 5R, 5L are found out so that the maximum load values LA-LD of the wheels and the durations TA-TD of presence of the load are memorized. The values LB/ LA, LD/LC, TB/TA, TC/TD are then calculated. The calculated values are compared with set values KL, KT. For example, when the value LB/LA is larger than that KL and the value TB/TA is smaller that than KL, the tire 3A is regarded as punctured. The accuracy of detection of puncture is thus promoted. |
