Abstract

The utility model provides an extensional beam structure of a heavy-duty car frame to overcome the problems that the machining cost of an abnormal frame rail of the existing heavy-duty car frame is higher, the machining period is longer, and the like. The extensional beam structure of the heavy-duty car frame comprises a left extensional beam, a right extensional beam, a cushion block and a bolt; the extensional beams are connected with the frame rail through the cushion block and the bolt; and the extensional beams adopt the structure which takes the shape of a slot and is provided with an upper wing surface and a lower wing surface. The extensional beam structure of the heavy-duty car frame has the beneficial technical effects that the frame rail of the heavy-duty car frame does not need to be stamped into the abnormal frame rail with certain flexibility and punches and molds with high requirements are not needed, so that the production cost is lowered, the production efficiency is improved, in addition, the structure of the frame is compact, the bearing capacity is high, the performances are reliable, and the assembly efficiency and the generality of the parts are also improved.

Description

Heavy motor vehicle vehicle frame overhanging beam structure

Invention field

The utility model relates to the heavy motor vehicle frame assembly, specially refers to heavy motor vehicle vehicle frame overhanging beam structure.

Background technology

The arrangement of prior art heavy motor vehicle generally is the type of drive that adopts engine behind front wheel, and under the increasing situation of driving engine profile, power, the water tank size that needs also can correspondingly increase, and the installation dimension of operator's compartment also can strengthen.Usually, the operator's compartment of heavy motor vehicle, driving engine and water tank are installed in the front portion of vehicle frame, need the front portion of vehicle frame be widened, to adapt to the installation of above-mentioned parts.The heavy motor vehicle vehicle frame of prior art adopts the mode machine-shaping of punching press usually, requires vehicle frame front wide and rear narrow, just need chassis side rail be struck out the special-shaped chassis side rail of certain sinuousness; Therefore; Processing is got up very complicated, to having relatively high expectations of punch press, and; Also need drop into some secondary moulds, tooling cost is higher.

Summary of the invention

Higher for the special-shaped chassis side rail tooling cost that overcomes prior art heavy motor vehicle vehicle frame, the process-cycle, the utility model proposed a kind of heavy motor vehicle vehicle frame overhanging beam structure than problems such as length.The utility model heavy motor vehicle vehicle frame overhanging beam structure comprises: left overhanging beam, right overhanging beam, cushion block and bolt; Overhanging beam is connected with chassis side rail with bolt through cushion block; Overhanging beam adopts flute profile and has top airfoil and the structure of lower aerofoil.

Further, the material thickness of the utility model heavy motor vehicle vehicle frame overhanging beam structure bathtub construction overhanging beam is 7～10mm, and section height is 300～340mm; The shape of last trough rim is front wide and rear narrow, wherein, is 43mm～48mm apart from front end 705mm scope insied width, and 323mm scope insied width is 33mm～40mm apart from the rear end, and the inclined-plane that broadens, centre is the arc transition of R155mm～200mm; Wide both sides are narrow in the middle of the shape of following trough rim, wherein, are 48mm～56mm apart from front end 290mm scope insied width, are 75mm～85mm apart from front end 350mm to 855 scope insied widths, and leaning on the width in the 325mm scope of rear end is 33mm～40mm.

The useful technique effect of the utility model heavy motor vehicle vehicle frame overhanging beam structure is the special-shaped chassis side rail that need the heavy motor vehicle chassis side rail not struck out certain sinuousness, need not drop into the punch press and the mould of having relatively high expectations, and has reduced productive costs; Improved production efficiency; And, the compact conformation of vehicle frame, bearing capacity is big; Dependable performance has also improved the commonality of efficiency of assembling and part.

Below in conjunction with accompanying drawing and specific embodiment the utility model heavy motor vehicle vehicle frame overhanging beam structure is further described.

The specific embodiment

Accompanying drawing 1 is the schematic three dimensional views of the utility model heavy motor vehicle vehicle frame overhanging beam structure, and accompanying drawing 2 is cross-sectional schematic of the linkage section of the utility model heavy motor vehicle vehicle frame overhanging beam structure, among the figure, and the 1st, left overhanging beam, the 2nd, right overhanging beam, the 3rd, cushion block, the 4th, longeron.Can know that by figure the utility model heavy motor vehicle vehicle frame overhanging beam structure comprises: left overhanging beam 1, right overhanging beam 2, cushion block 3 and bolt, overhanging

beam

1,2 is connected with chassis side rail 4 with bolt through cushion block 3.Obviously; The utility model heavy motor vehicle vehicle frame overhanging beam structure adopt cushion block and bolt with overhanging beam with after longeron is connected; Reached the front wide and rear narrow requirement of heavy motor vehicle vehicle frame, chassis side rail need not strike out the special-shaped chassis side rail of certain sinuousness, need not drop into the punch press and the mould of having relatively high expectations; Reduce productive costs, improved production efficiency.

Accompanying drawing 3 is schematic three dimensional views of the overhanging beam embodiment of the utility model heavy motor vehicle vehicle frame overhanging beam structure; Accompanying drawing 4 is sectional schematic diagrams of the overhanging beam embodiment of the utility model heavy motor vehicle vehicle frame overhanging beam structure; Accompanying drawing 5 is schematic top plan view of the overhanging beam embodiment of the utility model heavy motor vehicle vehicle frame overhanging beam structure, and accompanying drawing 6 is elevational schematic view of the overhanging beam embodiment of the utility model heavy motor vehicle vehicle frame overhanging beam structure.Can be known that by figure for guaranteeing the strength and stiffness of vehicle frame, the material thickness of the flute profile overhanging beam of the utility model heavy motor vehicle vehicle frame overhanging beam structure is 7～10mm, section height is 300～340mm.Equally, for guaranteeing the strength and stiffness of overhanging beam, the overhanging beam of the utility model heavy motor vehicle vehicle frame overhanging beam structure adopts bathtub construction, and upper and lower trough rim all is not a square, and promptly the trough rim width changes.The shape of the last trough rim of the bathtub construction overhanging beam of the utility model heavy motor vehicle vehicle frame overhanging beam structure is front wide and rear narrow; Wherein, Apart from front end 705mm scope insied width is 43mm～48mm; 323mm scope insied width is 33mm～40mm apart from the rear end, and the inclined-plane that broadens, centre is the arc transition of R155mm～200mm; Wide both sides are narrow in the middle of the shape of the following trough rim of bathtub construction overhanging beam, wherein, are 48mm～56mm apart from front end 290mm scope insied width, are 75mm～85mm apart from front end 350mm to 855 scope insied widths, and leaning on the width in the 325mm scope of rear end is 33mm～40mm.

Through above improvement, the utility model heavy motor vehicle vehicle frame overhanging beam structure need not strike out the heavy motor vehicle chassis side rail the special-shaped chassis side rail of certain sinuousness, need not drop into the punch press and the mould of having relatively high expectations; Reduce productive costs, improved production efficiency, and; The compact conformation of vehicle frame; Bearing capacity is big, and dependable performance has also improved the commonality of efficiency of assembling and part.
