Abstract
The invention relates to a center sill assembly for a heavy-duty railway wagon. The center sill assembly is characterized by comprising two parallel center sills, wherein the upper end face of each center sill is firmly connected with a center sill upper cover plate; the lower end faces of the two center sills are firmly connected into a whole through a center sill lower cover plate; a center sill connecting plate is arranged between draft sills at the two ends of the center sills; a plurality of center sill clapboards are arranged longitudinally between the two center sills between the two center sill connecting plates; the center sill clapboards construct a box-shaped structure together with the center sill upper cover plates and the center sill lower cover plate; the lower parts of the draft sills at the two ends of the center sills are provided with upper center plates which are matched with lower center plates of a bogie. The center sill assembly consists of box-shaped center sills constructed by fish-belly center sills, so that the center sill assembly has high vertical, transverse and torsional rigidity and can bear major stress of a wagon body. Meanwhile, the gravity center of the wagon body can be lowered, and the improvement on vehicle dynamics under high-speed running of vehicles is facilitated.
Description
Technical field
The present invention relates to a kind of railway truck, particularly about a kind of heavy－duty railway truck central sill, form.
Background technology
The existing vehicle central sill of China mainly adopts highly the H shaped steel assembly welding for 600mm or 630mm to become box-structure, and this kind of central sill rigidity and static strength cannot meet the load-carrying capacity of 92t.Also having part vehicle central sill to adopt the height of steel plate installed-welded is 800mm or 830mm, although this central sill can bear larger load-carrying, adopts steel plate installed-welded work capacity large, and work difficulty is high, and the welding deformation of generation is difficult for adjusting, and manufacturability is poor.Therefore, existing center sill structure has affected the further raising of railway truck load-carrying, and railroad train conveying efficiency and benefit are not high.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of railway truck central sill that can meet heavy－duty.
For achieving the above object, the present invention takes following technical scheme: a kind of heavy－duty railway truck central sill forms, it is characterized in that: it comprises two central sills that be arranged in parallel, the top airfoil of every described central sill is all fastenedly connected with a central sill upper cover plate, and the lower aerofoil of two described central sills is fastenedly connected and is integrated with a central sill lower cover; One central sill connecting panel is all set between the draw beam at described central sill two ends; Described in two, between two described central sills between central sill connecting panel, be vertically arranged with a plurality of central sill dividing plates, described central sill dividing plate and described central sill upper cover plate and central sill lower cover form box-structure; The draw beam bottom at described central sill two ends is provided with the body center plate matching with bogie truck truck center plate.
In a preferred embodiment, described central sill adopts H type shaped steel to cut into or steel plate installed-welded becomes variable section fish belly shape.
In a preferred embodiment, behind the H type cross section of the draw beam at described central sill two ends excision inboard wing limit, be flute profile.
In a preferred embodiment, 800mm heavy in section, described central sill middle part height is to the transition of the draw beam 350mm depth of section at described central sill two ends.
In a preferred embodiment, at described body center plate, place sets up cartridge brace panel, and described cartridge brace panel and described central sill length direction are symmetrical.
In a preferred embodiment, the top airfoil width of described central sill is 200mm.
The present invention is owing to taking above technical scheme, and it has the following advantages: 1, the present invention adopts variable section H-type steel fish belly central sill, guarantees central sill high cross section, middle part so that central sill when obtaining high rigidity, makes again its end cross-sectional meet carrying surface height.2, the present invention adopts the box central sill consisting of fish belly type central sill to form, thereby has larger vertical, horizontal and torsional stiffness, can bear the mainly stressed of car body.Meanwhile, can make body gravity reduce, be conducive to the lower dynamic (dynamical) improvement of vehicle of vehicle high-speed operation.3, because central sill of the present invention adopts fish belly shape H section steel beam, therefore reduce the work capacity with steel plate butt welding, reduced work difficulty, improved the manufacturability of manufacturing.
Accompanying drawing explanation
Fig. 1 is the front axonometric drawing that central sill of the present invention forms;
Fig. 2 is that the master that central sill of the present invention forms looks half view;
Fig. 3 is half view of overlooking of central sill composition of the present invention;
Fig. 4 is the reverse side axonometric drawing that central sill of the present invention forms.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.Yet only providing in order to understand better the present invention of accompanying drawing is provided, they not should be understood to limitation of the present invention.
As shown in Figure 1 to 4, central sill forms 1 and comprises central sill 11, central sill connecting panel 12, central sill dividing plate 13, central sill upper cover plate 14, central sill lower cover 15 and body center plate 16.Central sill 11 is two and be arranged in parallel, and the lower aerofoil center that the top airfoil of every central sill is all welded with 14, two central sills 11 of a central sill upper cover plate is welded as a whole with a central sill lower cover 15.For strengthening the strength and stiffness of draw beam (being the end of central sill 11), a central sill connecting panel 12 is all set between draw beam, make central sill 11 there are enough strength and stiffness.11 of two central sills between two central sill connecting panels 12 are vertically arranged with a plurality of central sill dividing plates 13, central sill dividing plate 13 also forms box-structure with central sill upper cover plate 14 and central sill lower cover 15, to strengthen vertical, the horizontal and torsional stiffness of central sill 11, make central sill 11 there are enough strength and stiffness to bear the vertical application force of the payload of freight container of curb girder, sleeper beam composition and each transverse beam transmission.Draw beam bottom is provided with body center plate 16, and it coordinates with bogie truck truck center plate, realizes location, the power transmission of car body on bogie truck.
In the above-described embodiments, central sill 11 can adopt H type shaped steel to cut into fish belly shape or adopt steel plate installed-welded to become fish belly shape, thereby realizes the heavy in section height of central sill 11 middle part 800mm to the transition of draw beam 350mm depth of section.
In the above-described embodiments, the H type cross section of draw beam is flute profile behind excision inboard wing limit, to guarantee the assembling space of coupler and draft gear in draw beam.
In the above-described embodiments, for coordinating the support of body center plate 16, and increase the local strength of central sill 11, at body center plate, 16 places set up cartridge brace panel 17, and cartridge brace panel 17 is symmetrical with central sill length direction.
In the above-described embodiments, the top airfoil width of central sill 11 is 200mm.
The various embodiments described above are only for illustrating the present invention, and wherein the structure of each parts, connection mode etc. all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
