Description
The present invention relates to a kind of series of combined chassis frames, particularly superimposed trailer and bogie vehicle frame.
General vehicle frame is the carrying of longeron single-beam formula, and except that direct biographies such as tire are stated from the ground-surface member, all parts nearly all are its loads; In bogie, vehicle frame and railway carriage load larrying member repeat, and cause the curb mass of vehicle big, the carrying surface height.This raw MAT'L that not only expends is more, also is unfavorable for energy savings, and is also influential to transportation safety and trafficability.In bogie, also exist suspension place two girder spaces in back narrower, outstanding bigger outside the railway carriage both sides, cause the vehicle lateral stability to owe desirable problem.
Alleviate the Vehicle preparation quality, its approach has a lot, as adopting to mould way such as Dai Gang.But to a vehicle frame that rams the loose soil with a stone-roller after sowing in must using also at present that steel make, greatly, people often prolong the pressure longeron with high tensile steel plate by mould and main equipment; In superimposed trailer, also the steel plate of useful different-thickness is made longeron by the welding of long weld seam; The hole of on the web of above-mentioned longeron, punching again that has, but owing to be the carrying of single-beam formula, therefore the curb mass that not only can alleviate is few, and the technology more complicated.The vehicle frame of pressing longeron is prolonged in employing, also have the renewal of product, must be subjected to pining down of mould renewal, moreover the material source of high tensile steel plate is also relatively more nervous.
In semi-trailer frame, also have and adopt highly less I-beam section, middle part along its web sections by certain tortuous rule, and then parallel shifted, welding, make it become a height I-beam section bigger, web band nature hole and make longeron, the chassis side rail of for example Polish D-18 type superimposed trailer is exactly this form.It truly has effect preferably to alleviating the vehicle frame curb mass, but because its technology is more complicated, the requirement on equipment and engineering factor is also higher, causes general producer to be difficult to reach.In addition, it also is the vehicle frame of longeron single-beam formula carrying, therefore still is difficult to fundamentally alleviate the curb mass of vehicle.
The height of vehicle carrying surface is concerning transportation safety, also influences the consumption of the energy, and is more relevant with its crossing ability.This is in general vehicle, and contradiction is also very not remarkable, and just more outstanding in freight container traffic, because this directly is decided by its whether problem of superelevation.The way that solves is the height of compression vehicle frame and traction seat contact portion.But this part highly is subjected to the control of respective cross-section moment of flexure, and more reduction can't be arranged.Therefore, in the large-tonnage container semi-trailer,, have to adopt the way of restriction tractor truck rear tyre diameter to solve for avoiding superelevation.For example JTBG35J40 ' the container semi-trailer of one of Ministry of Communication " six or five " national science and technology research project is exactly a representative type example.Like this, not only during vehicle operating need with spare tyre increase, and the numerical value of the carrying surface height that can reduce is also few.In addition, on the tire loading strength, can not say and do not have certain inadequate property.
Recently, in motor omnibus, employing " syllogic vehicle frame " is arranged, be that front and rear sections is a punching press flute profile straight beam, the stage casing is a framed structure, this truly has significant improvement with respect to the original one straight beam formula vehicle frame that leads to the end, but it can't solve the problem of the further compression of chassis frame height at bogie railway carriage, the repetition of vehicle frame load larrying member and superimposed trailer traction seat place.Moreover, itself also remain at back suspension place two girder spaces narrowlyer, hang greatlyyer railway carriage the both sides outside, cause the vehicle lateral stability to owe problems such as ideal.
