Background technology
Body drawing at vehicle is made the field, usually can be divided into self-supporting body and body-chassis frame construction, the former does not have independently vehicle frame, vehicle body is comprised of skeleton, housing and base plate and shifting board, wherein skeleton is divided into again hold skeleton and truss, housing comprises front coaming plate, rear end panel, left side coaming plate, right side coaming plate, top board, is provided with door, window, hatchcover etc. on the housing.Just as each assembly being installed and being born the matrix of various load, whole bodywork component all participates in carrying to vehicle body; And the latter has independently rigid-frame, and vehicle body separates with vehicle frame, the independent assembly of respectively doing for oneself, and vehicle body flexibly is fixed on the vehicle frame by suspending.Monocoque skin construction of the prior art is without the main longitudinal grider of carrying throughout, skeleton does not form the framework of relative closure, needs jointly to carry by housing, and integrally bending and torsional rigid are relatively poor, when larger load demand is arranged, just can't satisfy bending resistance and torsion stiffness requirement.
Summary of the invention
Technical matters to be solved by this invention provides preferably vehicle body of a kind of integrally bending rigidity and torsional rigid.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of vehicle body, comprise body framwork and housing, described housing surrounds body framwork, described body framwork is comprised of hold skeleton and truss, the symmetry that comprises described hold skeleton runs through left main longitudinal grider, the right main longitudinal grider of hold skeleton bottom, connects by some bottoms main beam between described left main longitudinal grider, the right main longitudinal grider; Described truss is comprised of two symmetrical top longerons and the link span that connects between described two top longerons and the described hold skeleton, and described two top longeron symmetries run through described truss top; Described left main longitudinal grider, right main longitudinal grider are respectively " Z " font longeron, are inverted trapezoidal, and the angle of described left main longitudinal grider, right main longitudinal grider and vertical guide is in 6 °-12 ° scope.Because left main longitudinal grider, right main longitudinal grider symmetry run through the skeleton bottom, guaranteed bending, the torsional stiffness of vehicle body integral body, improved the ability that vehicle body bears various static state, dynamic load, also guaranteed the space of running device; Connect by some bottoms main beam between left main longitudinal grider, the right main longitudinal grider, two top longeron symmetries run through the truss top, Effective Raise the bending stiffness of vehicle body.
Be provided with the first brace panel and the first reinforced rib between each parts of described truss and the left main longitudinal grider, be provided with the first brace panel and the first reinforced rib between each parts of described truss and the right main longitudinal grider.So that truss is reliable with being connected of left and right main longitudinal grider, has strengthened truss and born vertically and the ability of lateral impact.
Be provided with transition the second reinforced rib between each parts of described truss.Avoid truss junction stress raisers, strengthened the ability that truss bears static state, dynamic load.
The macropore place that offers on the described left main longitudinal grider is equipped with the second brace panel, and the macropore place that offers on the described right main longitudinal grider is equipped with the second brace panel.Avoid left and right main longitudinal grider stress raisers, strengthened the fatigue durability of left and right main longitudinal grider structure.
Door on the described housing, window, hatchcover place are equipped with reinforced bulkhead.Avoid stress raisers, strengthened the fatigue durability of housing structure.
The invention has the beneficial effects as follows that whole bodywork component all participates in carrying, be implicative of each other during each component load-bearing and coordinate, can make body quality little and integrally bending and torsional rigid are strong; Simultaneously, under attack or when bumping, vehicle body has even stand under load and with the ability of load diffusion, has improved year member's safety.
Description of drawings
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is further described in detail.
Fig. 1 is embodiment of the invention vehicle body framework construction scheme drawing;
Fig. 2 is embodiment of the invention vehicle body main longitudinal grider, bottom main beam local structure scheme drawing.
The specific embodiment
A kind of vehicle body, comprise body framwork and housing, housing surrounds body framwork, housing comprises on front coaming plate, rear end panel, left side coaming plate, right side coaming plate, top board, the housing and is provided with door, window, hatchcover, skeleton and housing carry jointly, mutually pin down during each component load-bearing and coordinate, have even stand under load and with the ability of load diffusion, Effective Raise the strength and stiffness of vehicle body.Its body framwork is comprised of hold skeleton and truss, as shown in Figure 2, the symmetry that comprises the hold skeleton runs through left main longitudinal grider 8, the right main longitudinal grider 1 of hold skeleton bottom, connect by many root bottom parts main beam 4 between left main longitudinal grider 8, the right main longitudinal grider 1, guarantee bending, the torsional stiffness of vehicle body integral body, improved the ability that vehicle body bears various static state, dynamic load.As shown in Figure 1, truss is comprised of two symmetrical top longerons 2 and several link spans 3 of connecting between two top longerons 2 and the hold skeleton, and two top longeron 2 symmetries run through the truss top, have improved the bending stiffness of vehicle body; Left main longitudinal grider 8, right main longitudinal grider 1 are respectively " Z " font longeron, are inverted trapezoidal, and left main longitudinal grider 8 is 9 ° with the angle of vertical guide, and right main longitudinal grider 1 is 9 ° with the angle of vertical guide, has fully guaranteed the space of Running System.Body framwork has been connected to form left main longitudinal grider 8, right main longitudinal grider 1, two top longerons 2 by the link span 3 of some layouts the rigid frame structure of a sealing, connect before and after the whole body framwork, link to each other up and down, about join, form firm, stable structure, can bear the various load of car load, and because body framwork has formed the framed structure of an integral body, the vehicle body stress point is evenly distributed, under attack or when bumping, the safety of carrying the member is improved.Be provided with the first brace panel and the first reinforced rib 7 between each parts of truss and the left main longitudinal grider 8, be provided with the first brace panel and the first reinforced rib 7 between each parts of truss and the right main longitudinal grider 1.Be provided with the second reinforced rib 5 between each parts of truss.The macropore place that offers on the left main longitudinal grider 8 is equipped with the second brace panel 6, and the macropore place that offers on the right main longitudinal grider 1 is equipped with the second brace panel 6.Door on the housing, window, hatchcover place are equipped with reinforced bulkhead.Avoid stress raisers, strengthened the fatigue durability of housing structure.
