The invention provides a straddle suspension type rail transit vehicle and a rail transit system.The straddle suspension type rail transit vehicle comprises a first carriage and a second carriage which are the same in structure, are arranged in parallel and symmetrically and are connected through a vehicle upper cross beam located on the upper portion; the bearing wheel is arranged between the first carriage and the second carriage, the bearing wheel is coaxially and rotatably arranged on the vehicle upper cross beam, and the distance between the bearing wheel and the first carriage is the same as that between the bearing wheel and the second carriage; the guide wheel sets comprise the upper guide wheel set and the lower guide wheel set and are arranged on the opposite carriage walls of the first carriage and the second carriage in the vertical direction in a spaced mode, and the upper guide wheel set is located below the bearing wheels. The device has the beneficial effects that the gravity center or the centroid of the carriage is ensured to basically coincide with the gravity center or the centroid of the bridge, and a vehicle cannot generate transverse additional bending moment on the bridge, so that the twisting effect on the bridge is avoided, the damage to the bridge is reduced, and the service life of the bridge is favorably prolonged.

    本发明提供了一种跨悬式轨道交通车辆及轨道交通系统,跨悬式轨道交通车辆,包括:结构相同的第一车厢和第二车厢,平行且对称设置,第一车厢和第二车厢通过位于上方的车辆上横梁连接;承重轮,设置在第一车厢和第二车厢之间,承重轮同轴且能转动地设置在车辆上横梁上,且承重轮与第一车厢和第二车厢之间的距离相同;导向轮组,包括上导向轮组和下导向轮组,沿竖直方向间隔设置在第一车厢与第二车厢的相对车厢壁处,且上导向轮组位于所述承重轮下方。本发明的有益效果是,确保了车厢的重心或形心与桥梁的重心或形心基本重合,使车辆不会对桥梁产生横向的附加弯矩,从而不会对桥梁产生扭动效应,减轻对桥梁的破坏,有助于提高桥梁的寿命。
