|発明の名称||WHEEL SUPPORT DEVICE|
PROBLEM TO BE SOLVED: To provide a wheel support device capable of supporting wheels so as to vibrate a whole rolling stock car including trucks at vibration test.
SOLUTION: Elastic support parts 17 and 18 of the wheel supporting device 16 are arranged between rails R1 and R2 and wheels 3a and 3b. When axle boxes of trucks are vibrated, the elastic support parts 17 and 18 are therefore elastically deformed, extended, and contracted to vibrate the trucks over railway tracks and vibrate the whole rolling stock car with the trucks. When the axle boxes at first and second locations are vibrated, at this time, vibrations tend to propagate from wheels 3a and 3b at first and second locations to wheels 3a and 3b at third to eighth locations through the rails R1 and R2, but the elastic support parts 17 and 18 block the propagation of the vibrations. Since movement restriction parts 19 and 20 restrict the movement of the wheels 3a and 3b, the wheels 3a and 3b are prevented from moving forwards and backwards, and to the sides and coming off of the rails R1 and R2.
