Description

Structure based on 12 meters bears city passenger train front suspension gasbag fixing base entirely

Technical Field

The utility model relates to a structure based on 12 meters bear city passenger train front suspension gasbag fixing base entirely belongs to city passenger train front suspension gasbag fixing base assembly technical field.

Background

In recent years, pure electric city buses with full-bearing type vehicle body structures are more and more in various cities in China, and the good performance of the full-bearing type vehicle body structures is widely accepted; adopt full bearing structure, make the driving of passenger train have agility, stationarity, travelling comfort and security more, in addition its humanized configuration, low emission, environmental protection ization, passenger space advantage such as big, the theory that embodies "science and technology is leading, people oriented" that modern society advocated has also made the unique product advantage of full bearing passenger train.

1. The whole body of the whole vehicle adopts a closed ring structure, the whole body participates in load, the upper part and the lower part of the body structure form a whole, and when the body bears the load, the shell of the whole body reaches a stable balance state.

2. The strength and rigidity of the whole vehicle are increased, and the vehicle body framework has enough strength due to the fact that the city passenger vehicle is in bad running conditions, such as serious overload, and the vehicle body framework is frequently started and braked. Numerous passenger car manufacturers in China can not solve the problem, and passenger door columns crack in sequence after the cars run for one or two years. The fully loaded body structure can effectively avoid the problems;

3. the comfort is good, and the noise is low; because the full-bearing vehicle body is used, all the connecting parts of the vehicle body and the underframe are welded to form a whole, no relative movement exists, no noise is generated, and a plurality of noise sources are reduced compared with other vehicle bodies.

4. The maximization of window glass, the same height and size uses the full-load automobile body, and side window glass can maximize, along with the acceleration of city construction, city beautification degree further improves, and city passenger train is mobile "viewing platform" again, more is favorable to appreciating city beauty scenery, and preceding shelves glass is bigger simultaneously, and the driver's field of vision is more open, has made things convenient for the operation.

The characteristic of the whole structure of the full-bearing type vehicle body is considered, the reliability of the whole structure of the full-bearing type vehicle body is guaranteed, and meanwhile, the local design structure of the full-bearing type vehicle body is reasonably adjusted and optimized, so that the advantage maximization is realized.

At present, the common structure of a 12-meter full-bearing type structure urban passenger car front suspension airbag fixing seat assembly is shown in figure 1, wherein the common structure comprises 1-an upper cover plate, 2-a reinforced vertical plate, 3-a left side plate, a right side plate and 4-a lower cover plate; as can be seen from the figure 1, the overall design structure of the existing common front suspension air bag fixing seat assembly is formed by 1 6mm upper cover plate, 2 6mm reinforcing vertical plates, 2 6mm left and right side plates and 1 6mm lower cover plate, and the whole is welded together by carbon dioxide arc welding; the disadvantages of the above structure:

1. the front suspension air bag fixing seat assembly with the common structure is formed by processing and welding 6mm steel plates, so that the purchasing cost is greatly improved;

2. the main body of the front suspension air bag fixing seat assembly with the common structure is made of a 6mm steel plate, so that the whole body is heavy;

3. after the front suspension airbag fixing seat assembly with the common structure is welded to the whole vehicle, the weight of the whole vehicle is greatly increased, and the aim of the light-weight design of the whole vehicle is greatly different.
