Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail. But should be by thisThe scope that is interpreted as above-mentioned theme of the present invention only limits to following embodiment.
In conjunction with Fig. 1-Fig. 6, a kind of railway lightweight type gondola car chassis by steel floor 8, central sill form 5,Sleeper beam composition 4, cross bearer composition 6, needle beam composition 7, train tail apparatus mount pad 1, gate beam groupOne-tenth 2 and false longeron 3 form, and this underframe does not arrange end carriage and curb girder, and underframe two ends are provided with train tail apparatusMount pad 1 and gate beam composition 2.
Central sill composition 5 is positioned at the middle part of underframe along the longitudinal direction of underframe, central sill composition 5 is by twoCold bending tank shaped steel assembly welding forms, and central sill composition 5 is provided with slave plate after integrated impact seat 5.1, monoblock typeSeat 5.2, body center plate 5.4, cartridge back-up ring 5.3 and dividing plate, monoblock type rear draft lug 5.2 draws with U-steelBe riveting and connect, good manufacturability, maintains easily; Body center plate 5.4 adopts high-strength bolt to be connected with U-steel,In ensureing connection reliability, improve maintainable; Cartridge back-up ring 5.3 is welded in body center plate 5.4Portion, can bear longitudinal impulse, reduces the longitudinal impact force at body center plate bolt place, improves underframe and bears vehicleThe ability of longitudinal impulse.
A composition sleeper beam composition 4 is respectively set at underframe two ends, and sleeper beam composition 4 is auxiliary vertical near two endsBeam composition 3 is also parallel to gate beam composition 2, and its two ends are respectively with central sill composition 5 with contain this underframeThe side wall assembly welding of open-top car connect, sleeper beam composition 4 is by upper cover plate, lower cover, web and stiffener groupWeldering forms, and web is between upper cover plate and lower cover, and sleeper beam composition 4 is positioned at whole on central sill composition 5Body formula rear draft lug 5.2 places, sleeper beam composition 4 is from central sill composition 5 to the side wall that contains this underframe open-top carCross section from large to small, forms the two web box type structure girders of variable cross-section, improves under the prerequisite of structural-load-carrying capacityAlleviate dead load, improve vehicle load.
Between two sleeper beam compositions 4, be furnished with three cross bearer compositions 6 and two needle beam compositions 7,Cross bearer composition 6 and needle beam composition 7 are formed by upper cover plate and lower cover, web and stiffener assembly welding,Web, between upper cover plate and lower cover, forms I shape section beam. The two ends of cross bearer composition 6 are dividedBe not connected with central sill composition 5 and the sidewall welding of the open-top car that contains this underframe, cross bearer composition 6 is from central sillFrom large to small, every two cross bearers form between 6 in composition 5 cross sections to the side wall that contains this underframe open-top carNeedle beam composition 7 is set, and it is 7 mutual that described sleeper beam composition 4, cross bearer composition 6, needle beam formParallel; False longeron 3 is arranged in underframe two ends and underframe middle part, and is parallel to central sill composition 5, the end of atAbove frame, lay steel floor 8.
Due to the two ends of the sleeper beam composition 4 on underframe and the side of central sill composition 5 and the open-top car that contains this underframeWall assembly welding connects, and the sidewall welding of the two ends of cross bearer 2.6 and central sill 2.5 and the open-top car that contains this underframe connectsConnect, headwall and the side wall of the open-top car that contains this underframe are welded to connect by corner post, make underframe, contain this endThe side wall of the open-top car of frame and headwall by overall all steel be welded to connect form a whole and underframe for no reasonThe stress frame structure of beam and curb girder. Because underframe employing is novel without end carriage and curb girder, and adopt change to cutFace box type structure girder and enclosed type section structure beam, adopt light-weight design and equal strength design concept, makesThe steel structure of car body that must contain the open-top car of this underframe forms rational overall stress frame structure, makes each carryingParts are stressed evenly, ensureing, under the prerequisite of vehicle strength and stiffness, to have reduced Undercarriage structure deadweight, fallThe steel structure of car body deadweight of the low open-top car that contains this underframe, has improved the load-carrying of vehicle bicycle.
Underframe is all steel Welding Structure, and main beam and plate adopt high-strength weather resisting steel, to strengthenAntiseptic property, improves vehicle service life, extends the car inspection and repair cycle, alleviates maintenance workload and transportCost.
The above is optimum way of the present invention, may utilize this for the designer in the design fieldInventive principle is done the profit of the forms such as name modifications, installation site exchange, material improvement, structural Shape OptimizationDecorations, any retouching on this basis and optimization are all in protection domain of the present invention.
