Abstract
The utility model is the improved rear frame of vehicle beam of a kind of loader, relates to the improvement of loader modular construction.It is characterized in that crossbeam docks the variable cross-section that one section cross section is made as mild continuous transition with body cradle, the side view of crossbeam Butt Section is that the mild of the trapezoidal side of body cradle extends continuously.Press the loader rear frame of vehicle beam that this programme is implemented, because of the Butt Section with former uniform section box girder and body cradle is improved to mild excessive box section girder continuously, and comparatively reasonably increased the intensity of crossbeam Butt Section and improved the anti-ability of destroying in Butt Section, prolonged the application life of loader relatively.The utility model structure is simple and direct, reasonable in design, is a kind of useful improvement.
Description
Technical field
The utility model relates to the improvement of loader parts, the particularly relevant improved rear frame of vehicle beam of a kind of loader.
Background technology
The back vehicle frame of existing a kind of loader, two uniform section box girders in its vehicle frame dock with being connected to of its anterior body cradle is direct, that is to say that prismatic box girder is an one with the body cradle weldering directly, the direct welding of this two unequal section objects, according to the principle of the mechanics of materials, its welding position promptly is a weakest stressed link.The use of such loader facts have proved, in the use behind the loader vehicle frame often destroy or the position of rupturing just at the joint of crossbeam and body cradle.Though employed this its type is the loader that the eighties in 20th century, typing was produced at present, and will be replaced by more advanced type gradually, but, in view of domestic existing still in a large amount of also reality of this type loader of extensive use of producing, in order better to use and further to improve existing loader usage ratio of equipment, the structure of above-mentioned existing loader rear frame of vehicle beam is awaited improving.
The utility model content
The purpose of this utility model, be for improving the weak link of existing loader rear frame of vehicle beam Butt Section structure, the improved rear frame of vehicle beam of a kind of loader is proposed, for realizing this purpose, adopt following technical scheme: the improved rear frame of vehicle beam of a kind of loader, comprise the uniform section box girder, it is characterized in that crossbeam docks the variable cross-section that one section cross section is made as mild continuous transition with body cradle, the side view of crossbeam Butt Section is the mild extension of the trapezoidal side of body cradle.
Press the loader rear frame of vehicle beam that this programme is implemented, because of the Butt Section with former uniform section box girder and body cradle is improved to mild excessive box section girder, and comparatively reasonably increased the intensity of crossbeam Butt Section and improved the anti-ability of destroying in Butt Section, prolonged the application life of loader relatively.The utility model structure is simple and direct, reasonable in design, is a kind of useful improvement.
Description of drawings
Fig. 1 for the side-looking of a kind of embodiment of the utility model, overlook and part variable cross-section schematic diagram;
Fig. 2 is that the side-looking of former back vehicle frame is with reference to schematic diagram.
The specific embodiment
Be further described in detail in conjunction with the accompanying drawings.According to the principle of the mechanics of materials, to the choosing and designing of same beam or rod member different parts section area, should be that the size by active force that bear at its position adapts, promptly be the cross section at stressed big position should be greater than its stressed little cross section.So, vehicle frame stressing conditions behind the loader, the position of its stressed maximum is progressively to reduce at the body cradle front end and to the rear portion of crossbeam.By this principle, adapt with docking of body cradle 2 actual state stressed for making crossbeam 1 with it, promptly be that a section of docking with body cradle of crossbeam should have rational a design.For this reason, the utility model is made as the side of body cradle 2 trapezoidal, the side view of connected crossbeam Butt Section is improved to the extension of the trapezoidal side of body cradle---and promptly the L section among the figure is trapezoidal, it so, promptly is the box girder that the prismatic box girder of former back vehicle frame is improved to variable cross-section (or unequal section).The cross section at c-c place is greater than the cross section greater than the a-a place, the cross section at b-b place as shown in the figure, and this Butt Section unequal section is mild continuous transition.Among the figure 3 is weld seams that crossbeam docks with body cradle.The phenomenon that the back vehicle frame of implementing after above-mentioned improvement comparatively rationally and has effectively overcome unbalance stress and easily fracture taken place and destroy.
Claims (2)
1, the improved rear frame of vehicle beam of a kind of loader comprises the uniform section box girder, it is characterized in that crossbeam docks the variable cross-section that one section cross section is made as mild continuous transition with body cradle.
2, by the improved rear frame of vehicle beam of the described loader of claim 1, the side view that it is characterized in that the crossbeam Butt Section is the mild extension of the trapezoidal side of body cradle.
