Abstract

A transverse swing control device for a side frame of a rail wagon comprises side frames, a spring supporting plate, a spring bearing seat, a spherical wear-resistant gasket and spherical positioningseats; and the two spherical positioning seats are respectively arranged on mounting surfaces of lower chord inner cavities of the central square frames of the two parallel side frames, and are transversely and symmetrically arranged along the side frames, and the centers of spheres of the spherical positioning seats are positioned in the longitudinal directions of the side frames, namely the central plane along the running direction of a vehicle. Transverse swing of the railway wagon side frames is effectively controlled through the two spherical positioning seats, the positioning reliabilityis 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 device of a railway freight car bogie side frame, in particular to a lateral swing control device for a gold railway freight car bogie side frame, which 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 bogies. [0003] Theoretical research shows (Shen Zhiyun, Research on the Dynamic Perfo...
