Abstract

A transverse swing control method for a wheel-rail low-power bogie is characterized in that spherical positioning seats are respectively mounted on mounting surfaces of inner cavities of lower chordsof central square frames of two side frames which are arranged in parallel on the wheel-rail low-power bogie, the spherical positioning seats are transversely and symmetrically arranged along the sideframes, spherical centers of the spherical positioning seats are positioned in the longitudinal direction of the side frames, namely a central plane along the running direction of a vehicle, and transverse swing of the side frames is controlled by the two spherical positioning seats. Transverse swing of the rail wagon side frames is effectively controlled through the two spherical positioning seats, the positioning reliability is high, and the problem of positioning reliability of a swing device in the prior art can be solved.

Description

technical field [0001] The invention relates to a component method of a side frame of a railway freight car bogie, in particular to a method for controlling the lateral swing of a bogie under low dynamic force of the wheel and rail. The method for controlling the lateral swing of the side frame can effectively control the lateral swing of the side frame; Technical field of railway wagon manufacturing. Background technique: [0002] With the development of heavy-duty railway wagon technology, increasing the axle load has become one of the main trends in the development of heavy-duty wagons. The increase of the truck axle load will bring about a significant increase in the efficiency of railway truck transportation, but at the same time the dynamic force between the wheels and rails will also increase significantly. Therefore, reducing the wheel-rail dynamics of railway freight car bogies has become one of the main objectives of the development of heavy-duty freight car bogie...
