To provide a railroad vehicle truck capable of reducing noise due to solid propagation sound inside a car by suppressing excitation to a truck frame from a main motor.SOLUTION: A railroad vehicle truck includes a truck frame, a forward main motor and a backward main motor respectively arranged on a forward position and a backward position of the truck frame, a forward wheel shaft and a backward wheel shaft respectively arranged on the forward position and the backward position of the truck frame, a forward driving device transmitting rotational force generated by the forward main motor to the forward wheel shaft, and a backward driving device transmitting rotational force generated by the backward main motor to the backward wheel shaft. The forward main motor and the backward main motor generate the rotational force in the opposite directions from each other. Any one of the forward driving device and the backward driving device has an inverse correction mechanism for inverting the direction of the rotational force and transmitting the force to the forward wheel shaft or the backward wheel shaft.SELECTED DRAWING: Figure 3

    【課題】 主電動機による台車枠への加振を抑制することにより、車内の固体伝搬音による騒音を低減できる鉄道車両台車を提供する。【解決手段】 この鉄道車両台車は、台車枠と、台車枠の前位と後位にそれぞれ配置された前位主電動機及び後位主電動機と、台車枠の前位と後位にそれぞれ配置された前位輪軸及び後位輪軸と、前位主電動機が発生する回転力を前位輪軸に伝達する前位駆動装置と、後位主電動機が発生する回転力を後位輪軸に伝達する後位駆動装置と、を備え、前位主電動機と後位主電動機とは、互いに逆方向に回転力を発生する。前位駆動装置または後位駆動装置の何れか一方は、回転力の方向を逆転させて前位輪軸または後位輪軸へ伝達する逆転補正機構を有する。【選択図】図3
