PROBLEM TO BE SOLVED: To provide a truck frame which can be commonly used for most kinds of vehicles whose locations of air springs are differently arranged and brings about improved efficiency of truck designing.SOLUTION: A truck frame of a railway vehicle comprises a pair of lateral beam bodies, longitudinal members which orthogonally cross the beam bodies on both sides of the beam bodies in the vehicle width direction and have insertion spaces extending in the vehicle width direction and formed between the pair of beam bodies, lower plates bridging the pair of beam bodies and the spaces between on both sides of the beam bodies in the vehicle width direction and lateral members extending in the vehicle width direction to be inserted in the insertion spaces and bonded not only to the lower plates from above but also to edge parts forming the insertion spaces, of the longitudinal members. The lateral members comprise column members having insertion spaces through which cylindrical parts projecting downward from bottom wall parts of air springs are inserted and a pair of reinforcement members neighboring the column members on both sides in the vehicle width direction.SELECTED DRAWING: Figure 2
【課題】空気バネ位置の異なる車種間で台車枠の大部分を共通化することを可能とし、台車の設計効率を向上させる。【解決手段】鉄道車両用台車枠は、一対の横梁本体と、前記一対の横梁本体の車幅方向両側部にて前記横梁本体に直交し、前記一対の横梁本体の間で車幅方向に延びる挿通空間が形成された縦部材と、前記一対の横梁本体の車幅方向両側部にて前記一対の横梁本体に架け渡された下板と、前記挿通空間を挿通して車幅方向に延び、前記下板に上方から接合されて且つ前記縦部材のうち前記挿通空間を形成する縁部に接合された横部材と、を備える。前記横部材は、空気バネの底壁部から下方に突出する筒部が挿入される挿入空間が形成された柱材と、前記柱材の車幅方向両側に隣接した一対の補強材と、を有する。【選択図】図2
