Abstract
The utility model provides a grooved girder type rear longitudinal beam with the central section thereof to be widened and provided with an inward opening, which comprises an upper wing plate, an outer side plate, an interior side plate and a lower wing plate mutually connected together. The upper wing plate, the outer side plate, the interior side plate and the lower wing plate are subjected to butt welding so as to form an enclosed grooved beam with the opening thereof to be facing the interior side plate. The inner sides of the central sections of both the upper wing plate and the lower wing plate are wider than the homolateral sides of the two end portions of both the upper wing plate and the lower wing plate. According to the utility model, different from the box-girder structure of a conventional rear longitudinal beam, the rear longitudinal beam provided by the utility model adopts an enclosed grooved-girder structure with an inward opening, wherein the central section of the rear longitudinal beam is widened. Therefore, the intensity of the rear longitudinal beam is increased, while the capabilities of the rear longitudinal beam in shock load resistance, bending load resistance, distortion load resistance and the like are improved. Meanwhile, the deformation and the fracture of the rear longitudinal beam of a vehicle frame due to the insufficient strength of the rear longitudinal beam are avoided.
Description
Technical field
The utility model relates to a kind of parts of heavy mining truck, refers to the grooved beam type floor side member that the middle part is widened, opening is inside on a kind of heavy mining truck vehicle frame particularly.
Background technology
The environment for use of heavy mining truck is abominable, and the carrying capacity of chassis of heavy mining truck is bigger, and the effect of the load that withstands shocks simultaneously, torque load and reverse load equal stress.
The back longitudinal beam structure of employed in the market heavy mining truck vehicle frame is the be upturned box girder of certain angle of low or rear portion, preceding high back.Floor side member and preceding protection thick stick, front side member, lifting bearing, back turning supporting seat are spliced into a unitized frame.
But said structure can be because overweight and stress concentration cause damages such as the fracture, distortion of vehicle frame, thereby influence the whole in-use performance of heavy mining truck.
Summary of the invention
The purpose of the utility model will overcome the existing in prior technology deficiency exactly, and the grooved beam type floor side member that the middle part is widened, opening is inside on a kind of heavy mining truck vehicle frame is provided.
For realizing above-mentioned purpose; The grooved beam type floor side member that the utility model institute widens at the design-calculated middle part, opening is inside; Said floor side member comprises interconnective upper flange, outer panel, interior plate and lower wing plate; Said upper flange, outer panel, interior plate and lower wing plate are welded into the closed trough girder of opening towards interior plate, and the inboard at the middle part of said upper flange and lower wing plate is all wide than the homonymy at its both ends.
Further, weld with the inboard of outer panel respectively the side of said upper flange and the side of lower wing plate, and the lower surface of said upper flange and the upper surface of lower wing plate weld with the outside of interior plate respectively.
The beneficial effect of the utility model is: make floor side member into the middle part is widened, opening is inside closed trough girder by the box girder of routine; To increase the intensity of floor side member; Strengthen the ability of its resistance to shock loads, flexural load and torsion loads etc., avoid the vehicle frame floor side member to produce the distortion fracture because of insufficient strength.The structure design of the utility model is more reliable, rationally, more can avoid the stress concentration at each position and cause vehicle frame to damage.
Description of drawings
Fig. 1 is the side-looking structural representation of heavy mining truck vehicle frame.
Fig. 2 is the cross-sectional view of floor side member among Fig. 1.
Fig. 3 is the plan structure scheme drawing of floor side member among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail.
The grooved beam type floor side member that middle part shown in Fig. 1～3 is widened, opening is inside, floor side member 1 comprise interconnective upper flange 2, outer panel 3, interior plate 4 and lower wing plate 5.Upper flange 2, outer panel 3, interior plate 4 and lower wing plate 5 are welded into the closed trough girder of opening towards interior plate 4, and the inboard at the middle part of upper flange 2 and lower wing plate 5 is all wide than the homonymy at its both ends.Weld with the inboard of outer panel 3 respectively the side of the side of upper flange 2 and lower wing plate 5, and the upper surface of the lower surface of upper flange 2 and lower wing plate 5 welds with the outside of interior plate 4 respectively.
Floor side member 1 makes the closed trough girder that the middle part is widened, opening is inside into by the box girder of routine; To increase the intensity of floor side member 1; Strengthen the ability of its resistance to shock loads, flexural load and torsion loads etc., avoid vehicle frame floor side member 1 to produce the distortion fracture because of insufficient strength.
