Description

Suspension structure for equipment box of rail vehicle underframe

technical field

The utility model relates to a suspension structure of an equipment box of a rail vehicle underframe, which belongs to the field of rail vehicle suspension structures.

Background technique

The structure of the existing electrical box under the rail vehicle is suitable for the suspension mode of the hook, but cannot cooperate with the suspension mode of the side beam and the cross beam. Therefore, in order to cooperate with the installation method of the underframe equipment of the side beam suspension car body and adapt to the development requirements of rail vehicles, it is urgent to design a simple, feasible, safe, reliable, and wide applicability electrical box installed under the side beam suspension method. suspension beam structure.

Utility model content

The utility model aims to provide a suspension structure for an equipment box of a rail vehicle underframe, which is simple, feasible, safe and reliable, and has wide applicability.

In order to achieve the above object, the technical solution adopted in the utility model is:

A rail vehicle underframe equipment box suspension structure, including a side beam installed at the bottom of the car body; its structural feature is that at least two suspension beams are installed at the bottom of the side beam, and the equipment box is installed at the bottom of the suspension beam; The two ends of the suspension beam are fixedly connected with the equipment box through reinforcing ribs, the upper part of the reinforcing rib is riveted or screwed with the bottom of the suspension beam, and the lower part of the rib is riveted or screwed with the side wall of the equipment box , and at the same time, the suspension beams, reinforcing ribs and equipment boxes are connected by welding or bonding.

Following is the further improved technical scheme of the utility model:

Further, the top of the equipment box is fixedly connected to the cross beam at the bottom of the vehicle body through a suspension beam.

In order to facilitate the adjustment of the relative position between the equipment box and the side beam, a vertical waist-shaped hole is opened on the reinforcing rib, and the waist-shaped hole is used as the installation interface between the equipment box and the vehicle body.

Preferably, spacers are provided between the suspension beam and the reinforcing rib, and between the reinforcing rib and the equipment box, through which the relative position of the equipment box and the side beam can be adjusted.

With the above structure, the suspension structure of the present invention is divided into two parts: the main body of the suspension beam and the reinforcing rib of the suspension beam, which can be installed with the electrical box under the suspension of the vehicle body with the side beam.

Compared with the prior art, the beneficial effects of the utility model are:

1. The structure of the suspension beam is simple, and the manufacturing process is difficult.

2. The suspension beam cooperates with the internal reinforcement ribs of the box body, and the suspension beam reinforcement ribs and other structures are established on the reliable connection of the box body, which is evenly stressed and safe and reliable.

3. In addition to the rivet connection, there is a welding connection between the suspension beam and the reinforcement rib of the suspension beam and the electrical box under the car, and the connection is firm.

4. The length of the suspension beam can be adjusted according to the structure of the box body, which has strong applicability.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

detailed description

A suspension structure for an equipment box on an underframe of an urban rail vehicle. As shown in FIG. The connection between rib 2 and equipment box 3 is treated with fillet welding to enhance the reliability of the connection. There is a waist-shaped hole on the reinforcement rib 2 of the suspension beam as the installation interface of the equipment box 3 on the chassis. The box 3 is connected to the vehicle body crossbeam by the suspension beam 1, and after the horizontal position is adjusted by the spacer, it is fixed with bolts to complete the installation of the underframe equipment box.

The utility model is mainly suitable for the suspension beam structure of the electric box body installed in the side beam suspension mode of urban rail vehicles, and this installation method is also suitable for other electric box bodies with similar structures, such as light rail vehicles, magnetic levitation vehicles, and EMU vehicles The suspension beam structure of the electrical box installed in the side beam suspension mode.

The above-mentioned embodiments should be understood that these embodiments are only used to illustrate the utility model more clearly, and are not intended to limit the scope of the utility model. After reading the utility model, those skilled in the art will understand each aspect of the utility model The modifications of all equivalent forms all fall within the scope defined by the appended claims of the present application.
