Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: a truck front lower protection device comprises a front lower protection cross beam 1 and a front lower protection connecting plate 3, wherein the front end of the outer wall of the front lower protection connecting plate 3 is fixedly connected with a front lower protection left and right support 2, the front left end of the front lower protection cross beam 1 is fixedly connected with a left pedal connecting plate 4, the front right end of the front lower protection cross beam 1 is fixedly connected with a right pedal connecting plate 5, the front lower protection cross beam 1 is integrally rolled and formed by 980dp cold-rolled dual-phase steel plates, a front protection plane is firstly rolled with 2 reinforcing ribs through a die to improve the structural strength of the front lower protection cross beam, then is rolled towards the back to form 2 rectangular square tubes, the front lower protection connecting plate 3 is fixedly connected to the left and right sides of the front end of the front lower protection cross beam 1, the front lower protection left and right supports 2 and the front lower protection connecting plate 3 are connected by M12 hexagonal bolts, the front lower protection end heads 6 are respectively installed at the left and right ends of the outer wall of the front lower protection cross beam 1, the front lower protection connecting plate 3, the left and right pedal connecting plate 4 and the right pedal connecting plate 5 are formed by stamping and bending 500L steel plates with the wall thickness of the front lower protection cross beam 1 by welding, the Q235 mm, and the lower protection cross beam with the front lower protection cross beam with the wall thickness;
through preceding protection crossbeam 1 down, preceding protection left and right sides support 2 down, preceding protection connecting plate 3 down, pedal connecting plate 4 in left side, pedal connecting plate 5 in right side and preceding cooperation between the protection end 6 down, make the structure to preceding protection crossbeam 1 down optimize, be character cut in bas-relief structure with the cross-section design, compare with traditional rectangle mouth style of calligraphy structure, the anti deformability is stronger after suffering the impact, simultaneously because 980dp diphase steel sheet that adopts high strength is behind integrative roll-in shaping, the wall thickness is 1.5mm by the 4mm attenuate, so the wall thickness is thinner, light in weight, it is relatively poor to have avoided traditional protector structure anti striking performance, yielding after the impact, and the wall thickness is thicker, whole weight is heavier, consequently, whole car weight increases, the problem of market competition advantage has been reduced.
Principle of operation
When the front lower protection device of the truck is required to be used, the front lower protection cross beam 1 is integrally formed by rolling 980dp cold-rolled dual-phase steel plates in a rolling mode, 2 reinforcing ribs are firstly rolled out on a front protection plane through a die, the structural strength of the front lower protection cross beam is improved, then the front lower protection cross beam is rolled to the back face to form 2 rectangular square tubes, then welding seams of the front protection plane is performed through a seam welder to form an integrated concave hollow closed structure, the wall thickness of the front lower protection cross beam is 1.5mm, the length of the front lower protection cross beam is 1960mm, the width of the front lower protection cross beam is 120mm, the height of the front lower protection cross beam is 84mm, round corners of the front lower protection cross beam are R8, and the front lower protection cross beam is installed at the front end of a frame and is welded with a front lower protection connecting plate 3, a left pedal connecting plate 4, a right pedal connecting plate 5 and a front lower protection end head 6.
The front lower protection connecting plate 3 and the left and right pedal connecting plates 4 and 5 are formed by stamping and bending 500L steel plates with the wall thickness of 5mm, the bent sections of the front lower protection connecting plates are concave and matched with the front lower protection cross beam 1, the front lower protection connecting plates are attached to the back side of the front protection plane of the cross beam 1 and are connected together through welding, and meanwhile the other side of the front lower protection connecting plate 3 serves as the mounting surface of the front protection left and right connecting support 2 and is connected through an M12 bolt.
The front lower protection end 6 is formed by stamping a Q235 steel plate with the wall thickness of 3mm and is connected with the front lower protection beam 1 through welding.
The front protection left and right connecting bracket 2 is of an angle seat structure formed by assembling and welding 2L-shaped triangular plates, is formed by punching, bending and assembling and welding 500L steel plates with the wall thickness of 8mm, and is used for connecting a truck girder and a front lower protection device assembly.
Compared with the traditional structure, the beam has the advantages that the strength is higher than that of the traditional rectangular cross section, the deformation resistance is improved by 40%, and the anti-collision and energy-absorption effects are obvious; the wall thickness of the beam is reduced by 60 percent (4 mm wall thickness of the original beam) compared with that of the traditional square beam, and the weight is reduced by more than 30 percent; the production process of the beam is simple, the whole beam is rolled by a steel plate and then only has one seam welding seam, and polishing is not needed in the later period.
Consequently in the use, the present case is optimized through the structure to preceding lower protection crossbeam 1, be character cut in bas-relief structure with the cross-section design, compare with traditional rectangle mouth style of calligraphy structure, anti deformability is stronger after being hit, simultaneously because the 980dp duplex steel sheet that adopts high strength is behind integrative roll-in shaping, the wall thickness is 1.5mm by the 4mm attenuate, so the wall thickness is thinner, light in weight, it is relatively poor to have avoided traditional protector structure anti-impact performance, yielding after the striking, and the wall thickness, whole weight is heavier, consequently, whole car weight increases, the problem of market competition advantage has been reduced.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
