Description
Technical field
The invention mainly relates to city rail vehicle engineering field, more particularly to a kind of city rail vehicle lightweight drawing pull bar.
Background technology
The drawing pull bar component of city rail vehicle is applied to, its primary structure is to draw club shaft and the compound bullet of metal-rubber
Property node, traction bar assembly by elastic panel nodes connection body and bogie, primarily served in vehicle operation connection and
The load effect of transmission traction braking, and reach vibration and noise reducing effect by elastic panel nodes.
Current drawing pull bar, the mounting hole for installing elastic panel nodes is provided with shaft two ends, and body of rod section is typically using circle
Shape, rectangle and I-shaped three kinds of structures, because the body of rod mainly uses high strength steel material, quality is larger, integrally seems and compares
It is heavy.
With the fast development of urban track traffic, passenger is to the speed of service of city rail vehicle and the riding comfort of vehicle
The requirement of more high-tech is proposed, used as one of effective solution, the development that Lightweight Technology has become city rail vehicle becomes
Gesture.Realize that light-weighted method mainly there are three kinds at present：1st, structure optimization is carried out to vehicle component, the body of parts is reduced
Product；2nd, using material substitution mode, original material is substituted with all kinds of lightweighting materials that new density is small, intensity is high；3rd, should
With advanced moulding process and process for treating surface, the intensity of material is improved, so as to reach lightweight target.In this 3 kinds of methods,
Light weight effect is obtained preferably in material substitution mode, product weight-loss ratio can reach more than 40%.
It is the development trend that current lightweight field is applied, the support and bar manufactured using fibre reinforced plastics to mould Dai Gang
Part, has applied in various types of vehicles.But the lightweight for realizing drawing pull bar for steel method to mould how is used, is traction
The problem for needing to solve in pull bar R ＆ D of complex.
At present, the light weight method of city rail vehicle drawing pull bar is generally structural optimization, or is substituted using high strength steel
Original material, the product weight-loss ratio that can be realized is less than 20%, it is difficult to reach final loss of weight target.For with circular or molding
The polymer composite pull bar of technological forming, its complex forming technology, and the bar structure of shaping is simple, it is impossible to meet urban rail
The requirement of vehicle drawing pull bar structure.Because the limitation of moulding process, the product structure of final molding are single, bar cross section is general
It is circular or rectangle.
The content of the invention
