力が、ブレーキがかけられている間台車に回転力
を及ぼし、そして走行方向に対して或る角度をな
す方向に台車を片寄らせる。(Problems to be Solved by the Invention) The braking system of the centering truck requires that an anchor of the braking system be attached to the truck bolster (lateral joist, cushion). Since the anchor is placed off center on the bogie bolster, the force couple created thereby exerts a rotational force on the bogie while the brakes are applied, and in a direction at an angle to the direction of travel. Move the cart to one side.
この回転力の作用が、台車の対角線的位置にお
けゆ車輪鍔（wheel flange）に対角線的に反対
側に位する車輪よりもより早い割合で磨耗を生ぜ
しめる傾向がある。 This rotational force action tends to cause wheel flanges at diagonal locations on the truck to wear at a faster rate than wheels located diagonally opposite.
それは更に、台車を一方へ片寄らせて、その方
向と一致する方向へ平行四辺形作用、即ち菱形作
り（lozenging）、を起させて、さらに対角線位置
の車輪鍔を益々磨耗させる。 It also causes the truck to shift to one side, causing a parallelogram effect, or lozenging, in a direction consistent with that direction, further increasing wear on the diagonally located wheel collars.

る。 Because the wheels are permanently attached to the axle,
A heavily worn wheel in a pair will dominate the rework period to recreate the correct shape, so to balance the wheels of the pair, the wheel that is not worn will have to More metal will be removed than would otherwise be required. This represents a waste of useful wheel tread metal.

The braking force causes the bogie to become irregularly shaped on a large scale, but this problem cannot be completely eliminated.

The steering arm member allows the bogie to assume a non-parallel attitude with its axles at track curves, eliminating irregularities caused by braking force on the bogie, reducing wheel wear, eliminating hunting, and therefore reducing traction force. This allows for low fuel cost operation. Further, a column 12 for pivoting the bogie at the curved track portion is provided on the upper surface of the central portion of the bogie bolster, and an elastic bearing plate 23 is arranged between the flat upper surface of the bogie around the column 12 and the car body pedestal. Therefore, it is possible to reduce the concentration of load at the edge of the flat top surface of the truck and maintain the cross-sectional strength.
