A vehicle frame assembly has reasonable rigidity and flexibility, has the functions of rigidity and flexibility, reduces stress, enhances the load-carrying performance of the whole vehicle frame, reduces the dead weight of the vehicle frame, and enhances the effective load of the whole motor vehicle.
Description
Technical field
The utility model belongs to automotive frame, relates in particular to a kind of improved variable section straight frame.
Background technology
Existing domestic heavy duty truck generally adopts the trapezoidal loading carriage of uniform cross section side bar formula, crossbeam is connected on aerofoil with longeron, though this vehicle frame structure, technology is simple, but the engine installation space is less, difficulty is installed, adaptive surface is narrow, especially can't satisfy the installation of the needed high-output engine of heavy duty truck, this vehicle frame makes that also the dynamic assembly center of gravity is higher, is unfavorable for improving the stability of enforcement, crossbeam is connected on aerofoil with longeron, make vehicle frame rigidity have a surplus, flexible not enough, stress is bigger, the integrated carrying poor-performing of frame assembly, the aerofoil connection mode also is unfavorable for the repacking needs of street rod producer, and in addition, this vehicle frame is comparatively heavy, raise unloaded WT, reduced the capacity weight of car load.
Summary of the invention
The purpose of this utility model is the trapezoidal loading carriage of a kind of later-model variable section side bar formula of design, improve vehicle frame dynamic assembly is especially heavily blocked the comformability that needed high-power dynamic assembly is installed, lower the center of gravity, improve riding stability, make frame assembly have rational rigidity and flexibility, accomplish hard and soft double Ji, reduce stress, improve the integrated carrying performance of frame assembly, reduce the vehicle frame deadweight, improve the car load capacity weight.
The purpose of this utility model is achieved like this: the trapezoidal loading carriage of a kind of variable section side bar formula, form by left and right longeron and front cross rail, after cross member, second road to the, seven road crossbeams, each cross-sectional plane that it is characterized in that frame assembly is a variable section, the transversal face width of leading portion, the posterior segment cross-sectional plane is narrow, and cross-sectional plane is gradual change place of fish belly tripe shape by wide narrow part, and this just can satisfy the installation requirement of the especially high-power assembly of each dynamic assembly; A left side, right vertical beam is all made with high strength alloy steel, a left side, the leading portion of right vertical beam i.e. a left side, right main longitudinal grider is an individual layer variable section flute profile girder steel, from front to back, its vertical fabric width changes from small to big, a left side, the posterior segment from gradual change place of fish belly tripe shape begins of right vertical beam is promptly left, right secondary longeron is double-deck uniform cross section flute profile girder steel, an and back segment left side hereinto, brace panel and reinforced support are set up in the inboard of right vertical beam, so both helped reducing the center of gravity of driving engine and attached assembly thereof, improve riding stability, also reduced cab heights, enlarge the visual field, improved the intensity of frame assembly again effectively;
In addition, except that being connected to aerofoil is connected of front cross rail, second crossbeam and the after cross member of vehicle frame and left and right longeron, the 3rd road crossbeam, the 4th road crossbeam, the 5th road crossbeam, the 6th road crossbeam, the 7th road crossbeam and be outside of belly riveted joint being connected of left and right longeron, eliminated stress effectively, guarantee that frame assembly has corresponding flexibility, and there is not rivet on the aerofoil of vehicle frame, for the repacking product provides utmost point advantageous conditions;
The trapezoidal loading carriage of variable section side bar formula that the utility model proposed, improved vehicle frame dynamic assembly has especially heavily been blocked the comformability that needed high-power dynamic assembly is installed, reduced center of gravity, improve riding stability, made frame assembly have rational rigidity and flexibility, accomplished hard and soft double Ji, reduced stress, improve the integrated carrying performance of frame assembly, reduced the vehicle frame deadweight, improved the car load capacity weight.
Now in conjunction with the accompanying drawings and embodiments the trapezoidal loading carriage of variable section side bar formula that the utility model proposed is further described.
Description of drawings
Fig. 1 is that the trapezoidal loading carriage master of variable section side bar formula that the utility model proposes looks scheme drawing.
Fig. 2 is that scheme drawing is looked on the trapezoidal loading carriage of the variable section side bar formula right side that the utility model proposes.
Among Fig. 1: 1, right vertical beam 2, left longeron 3, right main longitudinal grider 4, left main longitudinal grider 5, front cross rail 6, the second road crossbeam 7, the 3rd road crossbeam 8, the 4th road crossbeam 9, the 5th road crossbeam 10, the 6th road horizontal stroke 11, the 7th road crossbeam 12, after cross member 13, gradual change place 14, right secondary longeron 15, left secondary longeron
Among Fig. 2: 16,17 brace panels 18, reinforced support
The specific embodiment
From Fig. 1, Fig. 2 as can be seen: the trapezoidal loading carriage of a kind of variable section side bar formula, form by left and right longeron 2,1 and front cross rail 5 and after cross member 12, second road to the, seven road crossbeams 6,7,8,9,10,11, each cross-sectional plane that it is characterized in that frame assembly is a variable section, the transversal face width of leading portion, the posterior segment cross-sectional plane is narrow, and cross-sectional plane is fish belly tripe shape gradual change place 13 by wide narrow part, and this just can satisfy the installation requirement of the especially high-power assembly of each dynamic assembly; A left side, right vertical beam 2,1 all makes with high strength alloy steel, a left side, right vertical beam 2,1 leading portion i.e. a left side, right main longitudinal grider 4,3 is individual layer variable section flute profile girder steel, from front to back, its vertical fabric width changes from small to big, a left side, right vertical beam 2,1 the posterior segment from fish belly tripe shape gradual change place 13 beginnings is promptly left, right secondary longeron 15,14 is double-deck uniform cross section flute profile girder steel, an and back segment left side hereinto, right vertical beam 2, brace panel 16 is set up in 1 inboard, 17 and reinforced support 18, so both helped reducing the center of gravity of driving engine and attached assembly thereof, improve riding stability, also reduced cab heights, enlarge the visual field, improved the intensity of frame assembly again effectively.
