摘要： PROBLEM TO BE SOLVED: To provide a method and device for determining over load loading on the track by detecting the pressure of air springs supporting the car body. SOLUTION: The car body 1 of a railcar is supported on the track 31 (32) through the air springs 21 and 22 (23 and 24), wherein the air pressures P1 and P2 (P3 and P4) of the air springs 21 and 22 (23 and 24) on a track 31 (32) are measured by the air-electric converters 41 and 42 (43 and 44), and averaged with arithmetic processor 5 if this averaged value exceeds the set value, the over load is determined and the over load signal is output. The variations of internal pressures are canceled by averaging, the weight of the car can be detected with same precision as the precision at the time of not rolling. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To perform detection of excessive load by a simpler system constitution in a railway vehicle under the articulated truck system.
SOLUTION: The articulated truck 52 (two axle truck) having front and rear wheels 52C, 52D is arranged so as to straddle on vehicle bodies C
1 , C
2 of the first vehicle and the second vehicle. The front and rear vehicle bodies C
1 , C
2 are supported by the articulated truck 52 through air springs 52A, 52B. The other side of the vehicle body C
1 is supported by the truck 51 (two axle truck) having front and rear wheels 51C, 51D through air springs 51A, 51B. Further, the other side of the vehicle body C
2 is supported by the truck 53 (two axle truck) having front and rear wheels 53C, 53D through air springs 53A, 53B. Static converters 41, 42 are provided on a route of air pipes 21, 22 and are constituted so as to input an internal pressure signal AS1 of the air springs 51A, 51B and an internal pressure signal AS2 of the air springs 52A, 52B to an operation processing unit 3. It is determined whether or not it is the excessive load by the signals AS1, AS2.
