Abstract
The utility model relates to a lightweight welding framework, which adopts the integral structure of the welded framework, thereby simplifying the connecting structure among girders and effectively achieving lightweight improvement of the framework. The framework mainly comprises a pair of side girder assemblies, an end girder assembly, a cross girder assembly and a lengthways subsidiary girder assembly, wherein the side girder assemblies are connected with each other, and the lengthways subsidiary girder assembly is connected between the side girder assemblies at two sides; the side girder assemblies, the end girder assembly, the cross girder assembly and the lengthways subsidiary girder assembly are respectively connected in a welding way to form the integral structure; and the side girder assemblies and the end girder assembly are respectively formed by welding a plurality of steel plates. With the adoption of the characteristics of the basic scheme, the framework has the integral structure, the connecting structure among the girders and the lightweight design level can be effectively simplified under the condition of realizing the connecting stability and intensity.
Description
Technical field
The utility model improves at the integral structure of rail vehicle truck framework, belongs to mechanical manufacturing field.
Background technology
Follow domestic main line railway significantly to raise speed and the fast development of urban track traffic, require bogie of car framework to take into account the optimal design of lightweight and structural strength simultaneously.
Existing truck frame adopts the reinforced structure form usually, each parts all adopts comparatively complicated structure to be connected with the suspension installed device, characteristics are that big, the outside installation of weight is bigger with the load bearing component occupation space, are unfavorable for the lifting of framework self light-weight design and Vehicle Speed.
In view of this special present patent application that proposes.
The utility model content
Lightweight welded frame described in the utility model, its design goal are to solve the problem that above-mentioned prior art exists and the framework one-piece construction taking to be welded to connect, improve with the lightweight of simplifying connection structure between each beam, implementing framework effectively.
For realizing above-mentioned design goal, described lightweight welded frame mainly includes:
Interconnective a pair of curb girder is formed, end carriage is formed, crossbeam is formed;
The difference with the prior art part is that the curb girder of forming framework is formed, end carriage is formed, the crossbeam composition connects into the integral frame structure by welding respectively;
Curb girder is formed, the end carriage composition is welded by the several piece steel plate respectively.
As above-mentioned basic scheme feature, framework has one-piece construction, can simplify connection structure and light-weight design level between each beam under the prerequisite that realizes connective stability and intensity effectively.
For improving connective stability between the framework inner structure, be convenient to the installation of other equipment, crossbeam is formed and is had elongated steel-tube construction, and being welded with linear electric machine traction seat, two on steel pipe is traction seat and anti-side rolling torsion rod seat.
For improving the light-weight design performance that end carriage is formed, the end carriage composition is provided with integrated foundation brake mount pad.
Content to sum up, the advantage that described lightweight welded frame has is:
1, the one-piece construction of framework has been simplified the connection between each beam, implements lightweight effectively and improves design, helps high vehicle speeds.
2, the framework inner connecting structure is stable, can increase the safety of running at high speed under the antitorque commentaries on classics state of wide-angle.
Description of drawings
Now in conjunction with the following drawings the utility model is described further
Fig. 1 is the scheme drawing of lightweight welded frame;
As shown in Figure 1, curb girder composition 1, end carriage composition 2, crossbeam composition 3, linear electric machine traction seat 5, two are traction seat 6, foundation brake mount pad 7, anti-side rolling torsion rod seat 8.
The specific embodiment
Wherein, curb girder composition 1, end carriage composition 2 are welded by the several piece steel plate respectively.
Crossbeam is formed 3 and is had elongated steel-tube construction, and being welded with linear electric machine traction seat 5 and two on steel pipe is traction seat 6, anti-side rolling torsion rod seat 8
End carriage is formed 2 and is provided with integrated foundation brake mount pad 7.
