PROBLEM TO BE SOLVED: To realize measurement for attack angle between a wheel and a rail so that weight is reduced, durability is improved, resulting in providing cheap property and an excellent anti-noise property.SOLUTION: A distance sensor 15 measures distance between arrangement positions of wheel axles 14a, 14b for front and rear wheels in a vehicle moving direction of a two-axle cart 12 of a railway vehicle and a side surface of a rail 13 respectively. A displacement sensor 18 measures front and rear displacement of an axle box 16 at both sides in a vehicular width direction supporting the front wheel axle 14a. A calculator 19 calculates a yaw angle of the two-axle cart 12 from right and left displacement of the wheel axles 14a,14b for front and rear wheels calculated with the measurement distance measured by the distance sensor 15. In addition, wheel axle angle of the front wheel axle 14a is calculated with the front and rear difference in axis box 16 on both sides measured by the displacement sensor 18. Attack angle is calculated by adding a wheel axle angle of the front wheel axle 14a to the yaw angle of the cart.SELECTED DRAWING: Figure 1

    【課題】車輪とレールとのアタック角測定を、軽量で耐久性を向上させて、安価で、ノイズに強いようにする。【解決手段】鉄道車両の二軸台車12における車両進行方向前後の輪軸14a,14bの設置位置からレール13の側面までの距離をそれぞれ距離センサー15で測定する。前側の輪軸14aを支持する車両幅方向両側の軸箱16の前後変位を変位センサー18で測定する。演算器19で、距離センサー15で測定した前記測定距離を用いて求めた前後の輪軸14a,14bの左右変位から二軸台車12のヨー角を求める。また、変位センサー18で測定した前記両側の軸箱16の前後変位の差を用いて前側の輪軸14aの輪軸角を求める。これら台車のヨー角に前側の輪軸14aの輪軸角を加算し、アタック角を求める。【選択図】図1
