A lateral swing control method and device for side frame of railway freight car

Abstract

A lateral swing control method for side frame of railway freight car bogie is characterized in that two lateral oscillation control devices are respectively arranged in a central square frame of two side frames arranged in parallel, and spherical rotation pairs are arranged in that lateral oscillation control device; As that vehicle swing laterally, the spherical rotation pairs only generate relative rotation without lateral movement; The swing center of the side frame always coincides with the connecting line of the center of the two spherical hinges, so as to ensure that the swing device always maintains a good positioning state. The lateral swing of the side frame of the freight car bogie is restrained by the rotation of the spherical rotating pair, and the purpose of controlling the lateral swing of the side frame of the freight car bogie bogie is achieved.

Description

technical field [0001] The invention relates to a walking control method and device for railway freight cars, in particular to a lateral swing control method and a lateral swing control device for railway freight car bogie side frames, which are mainly used in heavy-duty transport railway freight cars and belong to the manufacturing technology of railway freight cars field. 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 res...

Problems solved by technology

[0016] The purpose of the present invention is to aim at the swing control device of the existing railway freight car bogie. When a larger lateral or longitudinal force is applied, there will be a dislocation between the two components of the swing motion pair, and this dislocation cannot be restored; at the same time, After the motion sub-components are worn to a certain limit, it is difficult to repair and must be replaced as a whole, which leads to the lack of reliability of the swing control device. A new type of lateral swing control method and lateral swing control device of the side frame is proposed to solve the problem of railway in the prior art. The positioning reliability of the swing device in the truck bogie is poor, and it is difficult to repair after the wear reaches a certain limit
