Abstract
The invention discloses an all-terrain vehicle longitudinal beam which belongs to an improved structure of crawler type engineering vehicle longitudinal beams, and aims to provide a crawler type engineering vehicle longitudinal beam with light weight, good bending resistance and torsional strength and strong obstacle crossing capability. The all-terrain vehicle longitudinal beam comprises a main beam, a drive wheel support which is fixed on the front end of the main beam, beam installation seats which are respectively fixed on the top surface of the drive wheel support and the top surface of the tail end of the main beam, a plurality of supporting wheels installation sleeves which are fixed on the main beam and a carrier roller installation seat, wherein the main beam (3) is of a box body-shaped structure which is formed by welding a left board (7) and a right board (8) which are of steel channel-shaped structures in a folding manner, the beam installation seats (4) are in steel channel-shaped structures, and a damping oil cylinder installation seat (6) is arranged on the main beam (3) and is close to the drive wheel support (1). The self weight of the all-terrain vehicle longitudinal beam is reduced, the bending resistance and torsional strength are improved, and moreover, harm which is caused by stress concentration is also reduced; and the improved structure is used for the all-terrain vehicle longitudinal beam.
Description
Technical field
The present invention relates to a kind of caterpillar engineering vehicles longeron, relate in particular to a kind of caterpillar engineering vehicles longeron and improve structure.
Background technology
Tracked ATV is a kind of amphibious multi-functional pair of car body Off-road vehicle for landform such as mountain region, snowfield, marsh, river shoal, desert, gullies, its operating environment is very complicated abominable, therefore require it must have cross-country crossing ability and higher maneuverability preferably, but also will possess good anti-seismic performance.Longeron is the main bogey of caterpillar engineering vehicles, and all drive element, compartment, chassis, the crossbeam of vehicle is all mounted thereto; Therefore longeron must have good bending resistance, torsional strength.At present, the longeron of common caterpillar engineering vehicles adopts straight plate welding or integral body to be stamped to form mostly, has the shortcomings such as complex structure, distribution of stress are concentrated, own wt is large; Can not meet the requirement of all-terrain vehicle.
Summary of the invention
For the above-mentioned defect that exists in prior art, the present invention aims to provide a kind of lightweight, bending resistance and torsional strength is good, obstacle crossing ability is strong all-terrain vehicle longeron.
To achieve these goals, the present invention is by the following technical solutions: it comprises girder, be fixed on the drive wheel bracket of girder front end, be separately fixed at this drive wheel bracket end face and described girder tail end end face the crossbeam mount pad, be fixed on a plurality of caterpillar wheel installation sleeves and upper track wheel mount pad on girder; Girder is that the crossbeam mount pad is channel-section steel shape structure by the left plate that is channel-section steel shape structure and the involutory box-like structure that is welded of right panel, and there is the damping cylinder installation seat position near drive wheel bracket on girder.
The center of drive wheel bracket is higher than the line of centers of girder.
Compared with the prior art, the present invention, owing to having adopted technique scheme, has changed longeron into box-like structure, has therefore not only alleviated own wt, has improved bending resistance and torsional strength, but also reduced bonding area, thereby reduced the harm that extending stress band comes.In addition,, due to the layout of having improved longeron, therefore the damping cylinder installation seat can be increased on longeron, thereby the anti-seismic performance of vehicle can be improved by the damping oil cylinder is installed.Due to the center of the drive wheel bracket line of centers higher than girder, thereby increase the angle of attach of vehicle, thereby improved the ability of the vertical leaping over obstacles height of vehicle.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of girder of the present invention;
Fig. 3 is the section drawing of girder of the present invention.
In figure: drive wheel bracket 1, caterpillar wheel installation sleeve 2, girder 3, crossbeam mount pad 4, upper track wheel mount pad 5, damping cylinder installation seat 6, left plate 7, right panel 8.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and specific embodiment:
As shown in Figures 1 to 3: girder 3 is by the left plate 7 that is channel-section steel shape structure and the involutory box-like structure that is welded of right panel 8, front end at girder 3 is welded with drive wheel bracket 1, at the end face of this drive wheel bracket and the tail end end face of girder 3, respectively is welded with the crossbeam mount pad 4 that is the channel-section steel shape; Be welded with a plurality of caterpillar wheel installation sleeves 2 that cross left plate 7 and right panel 8 on girder 3, and a plurality of upper track wheel mount pad 5; Position near drive wheel bracket 1 on girder 3 is welded with damping cylinder installation seat 6.
In order to improve the ability of car body leaping over obstacles, the center of drive wheel bracket 1 is higher than the line of centers of girder 3.
Claims (2)
1. all-terrain vehicle longeron, comprise girder, be fixed on the girder front end drive wheel bracket, be separately fixed at this drive wheel bracket end face and described girder tail end end face the crossbeam mount pad, be fixed on a plurality of caterpillar wheel installation sleeves and upper track wheel mount pad on girder; It is characterized in that: girder (3) is by the left plate (7) that is channel-section steel shape structure and the involutory box-like structure that is welded of right panel (8), crossbeam mount pad (4) is channel-section steel shape structure, in the upper position near drive wheel bracket (1) of girder (3), damping cylinder installation seat (6) is arranged.
2. all-terrain vehicle longeron according to claim 1, it is characterized in that: the center of drive wheel bracket (1) is higher than the line of centers of girder (3).
