Abstract
Larger for solving the weight that prior art heavy type automobile vehicle frame crossbeam assembly exists, structure is more complicated, and intensity and the problem such as rigidity is lower, the utility model proposes a kind of heavy type automobile vehicle frame crossbeam assembly.The utility model heavy type automobile vehicle frame crossbeam assembly, adopts unitized construction, comprises a crossbeam stage casing, two upper junction plates and four side connecting plates; Described crossbeam stage casing is that flute profile and slit opening arrange downwards; Described upper junction plate is the width that L shaped its length is greater than channel crossbar stage casing; Described side connecting plate is inclination bent; Described crossbeam stage casing, upper junction plate and side connecting plate are plate stamping part.Useful technique effect of the present utility model is to guarantee under the intensity of cross member of frame and the prerequisite of rigidity, solved the weight that prior art heavy type automobile vehicle frame crossbeam assembly exists larger, and structure is more complicated, and intensity and the problem such as rigidity is lower.
Description
Invention field
The utility model relates to heavy-duty automobile frame technology, specially refers to a kind of heavy type automobile vehicle frame crossbeam assembly.
Background technology
Conventionally, each midway location of heavy-duty automobile frame is all provided with crossbeam, and its Main Function is to increase chassis torsion rigidity, improves intensity and the rigidity of vehicle frame integral body.In addition, the drop hanger carrying on vehicle frame, brake system valve parts and electric system valve parts are also all fixed or are arranged on crossbeam.Therefore, outside the requirement of heavy type automobile vehicle frame crossbeam apart from intensity and rigidity, also have easy for installation, weight is lighter and the requirement such as simple in structure.Prior art heavy type automobile vehicle frame crossbeam assembly adopts channel crossbar middle section structure conventionally, and slit opening direction is arranged and horizontal direction parallel simultaneously, makes whole unbalance stress, has to increase the thickness of channel crossbar, to guarantee required intensity and rigidity.Obviously, it is larger that prior art heavy type automobile vehicle frame crossbeam assembly exists weight, and structure is more complicated, and intensity and the problem such as rigidity is lower.
Summary of the invention
Larger for solving the weight that prior art heavy type automobile vehicle frame crossbeam assembly exists, structure is more complicated, and intensity and the problem such as rigidity is lower, the utility model proposes a kind of heavy type automobile vehicle frame crossbeam assembly.The utility model heavy type automobile vehicle frame crossbeam assembly, adopts unitized construction, comprises a crossbeam stage casing, two upper junction plates and four side connecting plates; Described crossbeam stage casing is that flute profile and slit opening arrange downwards, and is provided with upper junction plate through hole at upper flat end, and side end is provided with side connecting plate through hole, and middle part, side is provided with parts mounting hole; Described upper junction plate is the width that L shaped its length is greater than channel crossbar stage casing, and its transverse plane is trapezoidal and is provided with crossbeam stage casing through hole, and vertical plane is rectangle and is provided with vehicle frame through hole; Described side connecting plate is inclination bent, is provided with crossbeam stage casing connecting bore in hypotenuse end, at horizontal edge, is provided with vehicle frame connecting bore; Described crossbeam stage casing, upper junction plate and side connecting plate are plate stamping part.
The useful technique effect of the utility model heavy type automobile vehicle frame crossbeam assembly is to guarantee under the intensity of cross member of frame and the prerequisite of rigidity, the weight that has solved the existence of prior art heavy type automobile vehicle frame crossbeam assembly is larger, structure is more complicated, and intensity and the problem such as rigidity is lower.
Accompanying drawing explanation
Accompanying drawing 1 is the three-dimensional structure schematic diagram of the utility model heavy type automobile vehicle frame crossbeam assembly;
Accompanying drawing 2 is the three-dimensional structure schematic diagrams in the utility model heavy type automobile vehicle frame crossbeam assembly crossbeam stage casing;
Accompanying drawing 3 is three-dimensional structure schematic diagrams of the utility model heavy type automobile vehicle frame crossbeam assembly upper junction plate;
Accompanying drawing 4 is three-dimensional structure schematic diagrams of the utility model heavy type automobile vehicle frame crossbeam assembly side connecting plate.
Below in conjunction with drawings and the specific embodiments, the utility model heavy type automobile vehicle frame crossbeam assembly is further described.
The specific embodiment
Accompanying drawing 1 is the three-dimensional structure schematic diagram of the utility model heavy type automobile vehicle frame crossbeam assembly, accompanying drawing 2 is the three-dimensional structure schematic diagrams in the utility model heavy type automobile vehicle frame crossbeam assembly crossbeam stage casing, accompanying drawing 3 is three-dimensional structure schematic diagrams of the utility model heavy type automobile vehicle frame crossbeam assembly upper junction plate, accompanying drawing 4 is three-dimensional structure schematic diagrams of the utility model heavy type automobile vehicle frame crossbeam assembly side connecting plate, in figure, 1-1 is crossbeam stage casing, 1-2 is upper junction plate, 1-3 is side connecting plate, 2-1 is upper junction plate through hole, 2-2 is side connecting plate through hole, 2-3 is parts mounting hole, 3-1 is vehicle frame through hole, 3-2 is crossbeam stage casing through hole, 4-1 is crossbeam stage casing connecting bore, 4-2 is vehicle frame connecting bore.As seen from the figure, the utility model heavy type automobile vehicle frame crossbeam assembly adopts unitized construction, comprises a crossbeam stage casing 1-1, two upper junction plate 1-2 and four side connecting plate 1-3; Described crossbeam stage casing 1-1 is that flute profile and slit opening arrange downwards, and is provided with upper junction plate through hole 2-1 at upper flat end, and side end is provided with side connecting plate through hole 2-2, and middle part, side is provided with parts mounting hole 2-3; Described upper junction plate 1-2 is the width that L shaped its length is greater than channel crossbar stage casing, and its transverse plane is trapezoidal and is provided with crossbeam stage casing through hole 3-2, and vertical plane is rectangle and is provided with vehicle frame through hole 3-1; Described side connecting plate 1-3 is inclination bent, is provided with crossbeam stage casing connecting bore 4-1 in hypotenuse end, at horizontal edge, is provided with vehicle frame connecting bore 4-2; Described crossbeam stage casing 1-1, upper junction plate 1-2 and side connecting plate 1-3 are plate stamping part.Because the utility model heavy type automobile vehicle frame crossbeam assembly adopts plate stamping part, combine, its weight is lighter, and structure is simpler.The utility model heavy type automobile vehicle frame crossbeam assembly crossbeam stage casing adopts upper junction plate to be fixedly connected with vehicle frame with side connecting plate, and the slit opening in crossbeam stage casing arranges downwards, not only actv. has increased Joint strenght, and actv. improved the force-bearing situation in connecting portion and crossbeam stage casing, effectively improved intensity and the rigidity of crossbeam assembly.And be arranged on various through holes or the connecting bore on crossbeam stage casing, upper junction plate and side connecting plate, facilitated upper junction plate, side connecting plate to be fixedly connected with crossbeam stage casing, facilitate being fixedly connected with of crossbeam assembly and vehicle frame, also facilitated being fixedly connected with of each type component.
Obviously, the useful technique effect of the utility model heavy type automobile vehicle frame crossbeam assembly is to guarantee under the intensity of cross member of frame and the prerequisite of rigidity, solved the weight that prior art heavy type automobile vehicle frame crossbeam assembly exists larger, structure is more complicated, and intensity and the problem such as rigidity is lower.
