Abstract
The utility model discloses a vehicle chassis with a diamond bar steel structure. A frame structure is composed of a draft sill and edge beams on the two sides of the draft sill, as well as a buffer beam in the front and a needle beam and a sleeper beam in the back. A diamond supporting mechanism which is composed of a crossbeam and a sloping beam is arranged in the middle of the frame structure, and longitudinal beams are connected between an acute angle end of the diamond supporting mechanism and the sleeper beam. After the diamond structure is combined with the longitudinal beams, the load applied to an end part can be decomposed and transferred to the edge beams and the draft sill through the diamond structure, then a part of the load is composed and transferred to the sleeper beam through the longitudinal beam assembly, thereby optimizing the structure of the chassis, enabling all parts in the overall structure to bear the acting force, and distributing the applied load reasonably. In addition, all the parts in the diamond structure and the longitudinal beam assembly adopt hot-rolling rectangular steel tubes, thereby enlarging the cross sections, improving the bending modulus of the parts, and enhancing the structural rigidity.
Description
Technical field
The utility model is to the improvement of existing guideway vehicle Undercarriage structure, and a kind of rhombus steel structure floor underframe for vehicle is provided, and belongs to the guideway vehicle technical field of structures.
Background technology
Existing guideway vehicle Undercarriage structure adopts the block form structure, parts such as needle beam, B-mode beam, stringer, side bar are parallel and vertical arrangement in its structure, part all adopts steel plate to be pressed into U or L shaped load, because the load forces dispense path is few, therefore, its structure can not satisfy the safety requirements of modern vehicle.
Summary of the invention
The utility model provides a kind of rhombus steel structure floor underframe for vehicle, has overcome the low shortcoming of existing guideway vehicle Undercarriage structure load.
Technical solution of the present utility model is as follows: the side bar of draw beam and both sides and forward and backward buffer beam thereof and needle beam, sleeper beam constitute framed structure, be provided with crossbeam and cant beam at the middle part of framed structure and constitute the rhombus supporting mechanism, longeron is connected between the acute ends and sleeper beam of rhombus supporting mechanism.
Good effect of the present utility model is: adopt diamond structure and longeron to combine, the load that is applied to the end is passed through diamond structure, at first load is decomposed and pass to side bar and draw beam, again that part load is synthetic afterwards, pass to sleeper beam by the longeron composition, by the underframe existing structure is optimized, parts are all bearing application force in the integral structure, and applied load is carried out reasonable distribution thus.All employings hot rolling rectangular steel pipe that parts in next diamond structure and longeron are formed, cross-sectional area become big, have increased the composite bending modulus of parts, have improved the rigidity of structure.
Description of drawings
Fig. 1 is the utility model structure principle chart.
1, buffer beam; 2, draw beam; 3, sleeper beam; 4, cant beam; 5, crossbeam; 6, cant beam; 7, side bar; 8, needle beam; 9, longeron.
The specific embodiment
According to shown in Figure 1, draw beam 2 constitutes framed structure with the side bar 7 of both sides and forward and backward buffer beam 1 and needle beam 8, sleeper beam 3 thereof, be provided with crossbeam 5 and cant beam 4,6 formation rhombus supporting mechanisms at the middle part of framed structure, longeron 9 is connected between the acute ends and sleeper beam 3 of rhombus supporting mechanism.
Claims (1)
1, a kind of rhombus steel structure floor underframe for vehicle, the side bar of draw beam and both sides and forward and backward buffer beam thereof and needle beam, sleeper beam constitute framed structure, its feature exists: be provided with crossbeam and cant beam at the middle part of framed structure and constitute the rhombus supporting mechanism, longeron is connected between the acute ends and sleeper beam of rhombus supporting mechanism.
