Abstract
The utility model relates to a chassis frame for the large-size passenger bus. The chassis frame for the large-size passenger bus is composed of a longitudinal beam and a cross beam made of groove type section shaping materials. The chassis frame for the large-size passenger bus is characterized in that the cross beam is sheathed and welded on the longitudinal beam in an integral interpenetrating type, and a reinforced plate is arranged in the connection part of the longitudinal beam and the cross beam. The stress bearing condition of the whole vehicle frame is reasonable, and the shape and the position of the chassis frame for the large-size passenger bus can be ensured when the cross beam is connected with the longitudinal beam, so the reliability and the safety of the large-size passenger bus can be ensured.
Description
Technical field
The utility model relates to a kind of improved motorcoach chassis frame structure.
Background technology
At present, in the domestic motorcoach chassis frame structure, the cross member of frame of stamping forming grooved section all is a segmentation structure, promptly by crossbeam and overhanging beam, is tied with longeron respectively by the method for welding or rivet.The shortcoming of this pattern is:
1, the vehicle frame stressing conditions is unreasonable, intensity difference.
Because overhanging beam is a cantilever beam, when its bearing load, the moment of flexure maximum that its root bore, and this position connecting portion of the welding of overhanging beam and longeron or riveted joint exactly, again because overhanging beam and crossbeam are not an integral body, so this position intensity a little less than, so infantile failure often appears in this position;
2, vehicle frame is yielding.
Because overhanging beam and crossbeam are not an integral body, the two is to be tied with longeron respectively by the method for welding or rivet, and therefore in the process and assemble process, its type shape and position degree all can not obtain failure-free and guarantee.
Summary of the invention
The purpose of this utility model is for overcoming the above-mentioned shortcoming that present domestic motorcoach chassis frame structure exists, proposing a kind of improved motorcoach chassis frame, with bulk strength and the making precision that improves the motorcoach chassis frame.
The utility model motorcoach chassis frame is made up of the longitudinal and cross beam that grooved section section bar is made, and it is characterized in that described crossbeam is that whole through structure is nested with, is welded on the longeron, and at the junction of longeron and crossbeam welding brace panel.
The advantage of the utility model motorcoach chassis frame is:
Through crossbeam makes the overhanging beam of traditional vehicle frame become as a whole with crossbeam, has increased its intensity greatly, makes the stressing conditions of whole vehicle frame more be tending towards reasonable; Because cross member of frame is a whole through structure, therefore when being connected with longeron, its type shape and position degree can both obtain failure-free and guarantee, make the reliability of motorcoach and safety obtain sufficient assurance.
