Hanging system of rail car

Abstract

The invention discloses a hanging system of a rail car, and belongs to the field of rail traffic. The hanging system comprises a supporting body. A rail is arranged above the supporting body, and a carriage is arranged on the side face of the supporting body. The hanging system further comprises a hanging assembly, one end of the hanging assembly is connected with a carriage box, the other end ofthe hanging assembly stretches into the rail, and the carriage is hung on one side of the rail. The hanging assembly comprises a hanging arm, a hanging part, a clamping part and a connecting part, wherein the hanging part is fixedly connected to the carriage body, the clamping part is clamped into the rail, and the connecting part is fixedly connected with a power drive device. In addition, a supporting structure for supporting the rail is provided with an inwards-concave auxiliary rail, and an auxiliary structure arranged on the carriage is clamped into an auxiliary rail. Traditional steel wire ropes or chains are replaced with the hanging system of the rail car, by the adoption of the mode that the hanging assembly is used for hanging and the side face auxiliary rail is used in cooperation, the carriage is supported and dragged, and the carriage runs along one side of the rail more stably.

Description

technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a rail vehicle suspension system. Background technique [0002] At present, the urban rail suspension device mainly adopts the following methods: using anti-off board, steel wire rope, chain, bolt assembly and other structures. Among them, the anti-off board needs to occupy a large installation space and has high requirements for the installation position, so it is not suitable for application in On rail vehicles, when steel wire ropes or chains are used, due to the relative movement between the car body and the horizontal beam, it is necessary for the steel wire ropes or chains to have a considerable margin. At this time, under certain conditions, they will sag and touch The horizontal beam will cause the horizontal beam to be worn and corroded, and even cause a fracture accident. The chassis equipment is directly hung on the lower surface of the chassis beam throu...

Problems solved by technology

[0002] At present, the urban rail suspension device mainly adopts the following methods: using anti-off board, steel wire rope, chain, bolt assembly and other structures. Among them, the anti-off board needs to occupy a large installation space and has high requirements for the installation position, so it is not suitable for application in On rail vehicles, when steel wire ropes or chains are used, due to the relative movement between the car body and the horizontal beam, it is necessary for the steel wire ropes or chains to have a considerable margin. At this time, under certain conditions, they will sag and touch The horizontal beam will cause the horizontal beam to be worn and corroded, and even cause a fracture accident. The chassis equipment is directly hung on the lower surface of the chassis beam through bolts and bolt assemblies. When the bolt breaks, because the equipment has no anti-off protection , will cause the equipment to fall off. This kind of hanging method has certain safety hazards and is easy to cause safety accidents. Only the method of hanging above is used to support the car body, and the stability is low.
