To provide a straddling type monorail vehicle in which a center pin provided in a vehicle body is mechanically fastened to a center pin holding portion of a bogie via a cushioning rubber with a small number of work steps, and an assembly method thereof.SOLUTION: In a straddling type monorail vehicle, a center pin of a bogie is formed in a hollow shape, and has a large cylindrical portion on a bolster beam side and a small cylindrical portion on a track side. A center pin holding portion is elastically supported by a bogie frame. A fixing metal fitting having a cylindrical rod shape is inserted through the center pin, and has a first threaded portion at an upper end portion thereof and a second threaded portion at a stepped lower end portion thereof. A lower metal fitting is disposed below the center pin holding portion, and has a female threaded hole to be threadedly engaged with the second threaded portion. An upper metal fitting is placed on an upper end surface of the center pin, and has a hole through which the first threaded portion penetrates. By threadedly engaging a nut with the first threaded portion that penetrates through the hole in a state in which the second threaded portion is threadedly engaged with the female threaded hole, the lower metal fitting is biased toward a lower end of the center pin, and the upper metal fitting is biased toward an upper end of the center pin.SELECTED DRAWING: Figure 3
【課題】少ない作業工数で、車体に備える中心ピンを台車の中心ピン保持部に緩衝ゴムを介して機械締結する跨座型モノレール車両、および組立て方法を提供する。【解決手段】跨座型モノレール車両において、その台車の中心ピンを中空形状とし、枕梁側の大円筒部と軌道側の小円筒部とを有する。中心ピン保持部が台車枠に弾性支持される。円柱の棒状の固定金具が中心ピンに挿通され、その上端部に第1ねじ部、段状の下端部に第2ねじ部を有する。下部金具が中心ピン保持部の下方に配設され第2ねじ部に螺合する雌ねじ穴を有しており、上部金具は中心ピンの上端面に載置され第1ねじ部が貫通する孔を有する。雌ねじ穴に第2ねじ部が螺合し状態で、孔を貫通した第1ねじ部にナットを螺合させることにより、下部金具が中心ピンの下端に、上部金具が中心ピンの上端に向かってそれぞれ付勢される。【選択図】図3
