Embodiment 1

[0028] as attached Figure 2-4 As shown, the present invention relates to a new type of side frame swing control device, including a side frame (1), a spring support plate (2), a spring bearing seat (3), a spherical wear-resistant liner (4), a spherical positioning seat ( 5).

[0029] Two spherical positioning seats (5) are arranged on the installation surface of the lower chord inner cavity of the central frame of the two side frames (1) arranged in parallel, and are symmetrical along the lateral direction of the side frames (horizontal direction perpendicular to the running direction of the vehicle) Arranged, the center of the ball is located in the longitudinal (along the running direction of the vehicle) center plane of the side frame (1).

[0030] A spring bearing seat (3) is arranged on the two spherical positioning seats (5) arranged on the same side frame, and there are two spherical positioning holes opening downward on the spring bearing seat (3), and the spherical ...

Abstract

A wheel-rail low-power-effect bogie with a transverse swing control device comprises a side frame transverse swing control device, a wheel set, a rolling bearing device, a bearing saddle, a splayed rubber elastic pad, a side frame assembly, a swing bolster assembly, a central suspension damping device, a normally-contacted elastic side bearing and a foundation braking device. The side frame transverse swing control device comprises side frames, a spring supporting plate, a spring bearing seat, a spherical wear-resistant gasket and spherical positioning seats; and the two spherical positioningseats are respectively arranged on the 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 directionof the vehicle. 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 railway freight car bogie structure, in particular to a wheel-rail low-power bogie with a lateral swing control device, which can effectively The invention relates to controlling the lateral swing of a side frame; it belongs to the 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 Dynam...
