The specific embodiment
Hereinafter will be in conjunction with the accompanying drawings the chassis and the vehicle body framework construction of expansion van-type semitrailer of the present utility model be elaborated.
Fig. 1 a and Fig. 1 b are respectively the front elevation and the birds-eye vieies on the chassis of expansion van-type semitrailer, and Fig. 1 c is the section drawing of the chassis of expansion van-type semitrailer along the intercepting of the A-A among Fig. 1 b.As seen, this chassis has towing pin 1 from these figure, and this towing pin is used for linking to each other with tractor truck.In embodiment of the present utility model, can adopt 50# or 90# pin, it can be changed mutually.This chassis also comprises fixed bearing 2, and this is fixedly supported upon when superimposed trailer and tractor truck link and is withdrawn in the bottom of superimposed trailer, and reaches ground when tractor truck breaks away from superimposed trailer always, is used to support superimposed trailer, keeps the balance of superimposed trailer.As required, one or more such supportings can be set.Chassis of the present utility model also comprise girder 3 with " worker " font section structure and by the hole on the girder web through running through crossbeam 4 between two girders, this runs through crossbeam and main Vehicle body skeleton is rigidly connected, make main Vehicle body skeleton and chassis be combined as an integral body, main Vehicle body skeleton is shared part bending and torque load.The chassis also has and is arranged on described girder 3 outsides, the false longeron 5 parallel with described girder roughly, and it plays interconnect function.The many deep beams 6 on chassis are used to connect two girders 3, two girders are become one.Can be clear that from above-mentioned each figure the two side ends that runs through crossbeam 4 on described chassis does not have side bar.In addition, the chassis also comprises circuit (not shown), brake equipment and the gas circuit (not shown) thereof of air bag suspension and vehicle bridge 7, tire, wheel rim, ABS complemental brake system 8, spare tyre 9, consumer, these parts and master, crossbeam organically combine, and form complete chassis system.
Fig. 2 a is an expansion van-type semitrailer at the viewed diagrammatic sketch of a side that launches fully under (withdrawal) state from body framwork, Fig. 2 b is that expansion van-type semitrailer is launching under (withdrawal) state fully from the viewed diagrammatic sketch of the opposite side of body framwork, Fig. 2 c diagrammatic sketch that to be expansion van-type semitrailer observe forward behind the car at retracted mode under body skeleton fully, Fig. 2 d diagrammatic sketch that to be expansion van-type semitrailer observe forward behind the car at deployed condition under body skeleton fully, Fig. 2 e is the birds-eye view of the body framwork of main envelope of including of expansion van-type semitrailer and two secondary envelopes.By among these figure as seen, body framwork comprises main Vehicle body skeleton 10, respectively exists a large-scale planer-type hole, the horizontal direction at the hole to have two on the side wall frame of the main envelope left and right sides and expands the scalable secondary envelope 11,12 that and withdraw in the direction.The undersized of secondary envelope is in the size at hole, and these two secondary envelopes can be mutually nested and can be nested in the main envelope 10.Under the state of withdrawal fully, the outer side skeleton in scalable railway carriage or compartment and main envelope side wall frame are basically on a common plane.Simultaneously, being arranged on two front and back aperture of doors on the scalable envelope overlaps basically, form a passage that to become owner of envelope, make and still can normally utilize vehicle under the state of withdrawing fully in scalable railway carriage or compartment, this moment, expansion van-type semitrailer can be by tractor truck cruising on road.Under expansion did well fully, main envelope floor and scalable secondary envelope floor were on same horizontal surface, and scalable railway carriage or compartment does not have obviously sagging.The floor area that provide this moment is equivalent to three times under the state of withdrawal fully basically.Body framwork adopts the rectangular frame and the diagonal rib structure design of " well " font, guarantees that fully vehicle body has enough strength and stiffness.Simultaneously, adopt light-weight design, use the rectangular tube steel of high strength, light weight, alleviate complete vehicle quality.
Fig. 3 is that the skeleton scheme drawing is enclosed in the main envelope left side of expansion van-type semitrailer.Can see that from this figure this body framwork has the roof rail 13 that section is less, span is long.In general, cause bending easily because little, the span of section is long, sinuousness is excessive will to have a strong impact on scalable envelope motion, in embodiment of the present utility model, adopts truss structure design and pre-arch technology to solve the problem of crooked deformation thus.
Fig. 4 a is the scheme drawing that attaches together of the chassis of expansion van-type semitrailer and main Vehicle body skeleton, Fig. 4 b shows car front end face scheme drawing, Fig. 4 c shows gooseneck district cross sectional representation, the dress welding position of Fig. 4 d demonstration chassis and main Vehicle body skeleton is put scheme drawing, Fig. 4 e shows car aft end face scheme drawing, and Fig. 4 f is the section drawing along the intercepting of the B-B among Fig. 4 d.The connection location relation that from these several figure, can more clearly reflect this chassis and body framwork, wherein, described chassis becomes as a whole with described body framwork through behind the assembly welding, thereby makes the chassis of this vehicle and vehicle body framework construction become an integral structure pattern.Particularly, the front wall frame 15 of main envelope and rear wall frame 16 are integrally welded with chassis front edge crossbeam and lagging dege crossbeam respectively, and skeleton 17 and right side are enclosed in the left side of main envelope, and to enclose skeleton 14 integrally welded with the two ends of a plurality of crossbeams 4 on chassis respectively; One end of a plurality of cantilever beams 18 that can transversal stretching laterally is welded on the upper surface on chassis, and two secondary envelopes are integrally welded with the free outer end of the cantilever beam of each side respectively.
Above with reference to the accompanying drawing illustrated embodiment the utility model is had been described in detail, but it should be appreciated by those skilled in the art, the utility model is not limited to these certain embodiments, but can carry out variations and modifications to it under the situation that does not depart from scope of the present utility model or spirit.
