Abstract
The utility model relates to a high-strength steel frame of a light truck. The high-strength steel frame is composed of a left longitudinal beam, a right longitudinal beam and more than two cross beams, wherein the left longitudinal beam and the right longitudinal beam are in split structure; the longitudinal beam on each side comprises a longitudinal beam body and a front section of the longitudinal beam; and the front section of the longitudinal beam is sheathed on the front end of the longitudinal beam body and is connected and fixed by a rivet. The high-strength steel frame of a light truck is characterized in that the front-end structure of the novel frame adopts a stamping form and is installed in a riveting mode. The front-end structure of the frame is analyzed by a finite element and is verified by a road experiment to ensure that the frame has enough strength and proper rigidity, and the phenomenon that a frame assembly is subjected to torsion damage and bending breakage of the longitudinal plane is avoided under different load and road surface situations.
Description
Technical field
The utility model belongs to running car system technical field, is specifically related to a kind of light-duty truck vehicle frame front-end architecture.
Background technology
Present stage, light truck frame longeron adopted the longeron form of unequal section, and the upper surface of longeron is along the constant or local reduction of total length, and the lower surface at two ends is according to the stress situation, and suitable upwards shrinks.
The longeron of unequal section must adopt the mode of drawing to make, and can not adopt rolling formation, high strength steel material drawing difficulty, and manufacturability is bad; Because the leading portion alternation of cross-section will change whole longeron shape, so the commonality of unequal section longeron is bad; Because manufacturing needs shaping dies, so time-to-market is long, minimum needs 60 days.
Traditional longeron need improve the manufacturability of stringer forming, improves the commonality of longeron, shortens the time-to-market of longeron.
The utility model content
The utility model is optimized from the frame assembly front-end architecture; The form that installs uniform cross section (symmetry convergence) longitudinal beam front section combination through the longeron front end additional solves the Cab mounting problem of the frame assembly of uniform cross section longeron; Improve the universalization of longeron, accelerate the longeron product development cycle.
The technical scheme that the utility model adopted is:
A kind of high strength steel vehicle frame of light truck, said vehicle frame is connected to form by left longeron, right vertical beam and plural crossbeam; Said left longeron and right vertical beam are for dividing body structure, and every side girder comprises longeron body and longitudinal beam front section, and longitudinal beam front section is set in longeron body front end and connects fixing through rivet.
Said longitudinal beam front section is whole flute profile, and two ends are the pipe reducer structure, and microcephaly's one side is an anterior extension end, and big first side is a coupling end, and anterior extension end is connected with the symmetry convergence transition phase of coupling end through the middle part;
The coupling end of said longitudinal beam front section is sleeved on the joint portion of the longeron body and second crossbeam;
Connecting first crossbeam between the anterior extension end of said both sides longitudinal beam front section.
The wide of said longitudinal beam front section is 81mm; The anterior extension end height 121mm of said longitudinal beam front section; The coupling end height of said longitudinal beam front section is less than 242mm.
The useful technique effect of the utility model is following:
Manufacturability: prismatic longeron form, can adopt rolling formation, make high strength steel be applied to chassis side rail, improved the manufacturability of the longeron of high strength steel greatly.
Commonality:, can improve the commonality of longeron because the employing longitudinal beam front section adds the array configuration of longeron.
Time-to-market: longitudinal beam front section, shaping dies exploitation only needs 20 days, compares with 60 days of stringer forming mould, has shortened the cycle of exploitation greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the longitudinal beam front section birds-eye view of Fig. 1.
Fig. 3 is the longitudinal beam front section lateral plan of Fig. 1.
Among the figure: left longitudinal beam front section 1, right vertical beam leading portion 2, first crossbeam 3, second crossbeam 4, left longeron body 5, right vertical beam body 6, rivet 7.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done explanation further through embodiment.
Embodiment:
Referring to Fig. 1-Fig. 3, a kind of high strength steel vehicle frame of light truck, vehicle frame is connected to form by left longeron, right vertical beam and plural crossbeam; Left side longeron and right vertical beam are for dividing body structure, and every side girder comprises longeron body and longitudinal beam front section, and longitudinal beam front section is set in longeron body front end.Left side longeron body 5 adopts the QSTE650-6 material with right vertical beam body 6; Left and right longitudinal beam front section adopts the 510L-6 material to meet the GB/T3273 standard.
Left side longitudinal beam front section 1 is whole flute profile with right vertical beam leading portion 2, and two ends are the pipe reducer structure, and microcephaly's one side is an anterior extension end, and big first side is a coupling end, and anterior extension end is connected with the symmetry convergence transition phase of coupling end through the middle part; The wide of longitudinal beam front section is 81mm; The anterior extension end height 121mm of said longitudinal beam front section; The coupling end height of said longitudinal beam front section is less than 242mm (can be used for a series of different model car bodies).
The coupling end of longitudinal beam front section is sleeved on the joint portion of the longeron body and second crossbeam 4; Connect fixing through rivet 7; Connecting first crossbeam 3 between the anterior extension end of left side longitudinal beam front section 1 and right vertical beam leading portion 2; Be used to improve the torsional stiffness of vehicle frame front end.
