PURPOSE: A flexible trolley having one articulation is provided to improve performance of maintenance by installing plural elastic displacing devices between separated trolley frames and to make the trolley smoothly run on curve rails with variability of an elastic displacing device in running at high speed. CONSTITUTION: In a trolley for a railway vehicle having wheels and two axles(2a,2b) installed to a wheel(1), trolley frames(3a,3b) are connected to the axles each and the trolley frames are formed separately. Joint portions are prepared at the connecting part of the trolley frames. A mounting frame(4) having width to be able to cover clearance between separated trolley frames to function as a bolster in coupling of a body is installed to the upper end surface. An elastic displacing device(6) raising elastic displacement corresponding to the power reciprocally acting is connected to the edge of a trolley frame. Therefore distribution of the power transmitted to the elastic displacing device is changed and the trolley smoothly runs on the curb rails. |
