Abstract
The present invention relates to a kind of guideway vehicle heavy stand formula sleeper beam structure, composition comprises: upper cover plate, lower cover, web, it is the corresponding breach of steel spring that lower cover offers with bogie truck two, gap position is fixed with for inserting the box body that bogie truck two is steel spring upper end, box body is between lower cover and upper cover plate, box body coordinates with breach and forms heavy stand structure, it is the pin-and-hole that steel spring locating dowel pin inserts that the top of box body offers for two, and it is the locating dowel pin mount pad that steel spring locating dowel pin inserts that the back of box body is fixed with for two.It is the bogie truck adopting steel spring that sleeper beam of the present invention is applicable to two, and steel spring is placed in more than bolster, improves curve passing through crossing ability, reduces manufacture and the maintenance cost of vehicle simultaneously; The heavy mesa structure of sleeper beam of the present invention, sinks to sleeper beam inside by sleeper beam and bogie truck steel spring interface, is strengthened the intensity of heavy stand box body and locating dowel pin mount pad, can meet rigidity and requirement for height that two are steel spring by gusset.
Description
Technical field
The present invention relates to guideway vehicle heavy stand formula sleeper beam structure, belong to chassis of rail vehicle technical field.
Background technology
Sleeper beam is one of topmost load member of railroad car bodywork, and the weight of car body is all passed on bogie truck by it.And form a pair " draw and combine " with bogie truck and be with motor vehicles bodies or bogie truck to run quickly in orbit.
Along with domestic passenger train export increasing, how to meet route requirements that some are external complicated, become passenger train and manufacture and design middle problem demanding prompt solution.
Because national line condition is relatively better, common domestic passenger train structure cannot meet the relatively little radius of curve requirement of some external circuits, in addition some state-owned railroads operation ability external is relatively weak, line security is not good, design one good by performance, easy to maintenance, the structure that safety is high, effectively can promote the developing of foreign market.
Bolster structure bogie truck under applicant applied for guideway vehicle in 2012, its secondary suspension adopts air bellow, is provided with corresponding empty spring mounting seat below sleeper beam.The bogie truck of this form is comparatively widely used at present, and its comfort level is high, and controllable degree is done, but manufacture, maintenance cost is too high, cannot adapt to the demand of low developed area.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the above-mentioned shortcoming of prior art, provides a kind of guideway vehicle heavy stand formula sleeper beam structure.
In order to solve above technical matters, guideway vehicle heavy stand formula sleeper beam structure provided by the invention, composition comprises: upper cover plate, lower cover, web, it is characterized in that: it is the corresponding breach of steel spring that described lower cover offers with bogie truck two, described gap position is fixed with for inserting the uncovered box body that bogie truck two is steel spring upper end, described box body is between lower cover and upper cover plate, described box body coordinates with breach and forms heavy stand structure, it is the pin-and-hole that steel spring locating dowel pin inserts that the top of described box body offers for two, it is the locating dowel pin mount pad that steel spring locating dowel pin inserts that the back of box body is fixed with for two.
Further, dividing plate is fixed with between described box body and web.
Further, gusset is fixed with between the back of described box body and locating dowel pin mount pad.
Further, the both sides of sleeper beam are fixed with draw beam draw-bar seat.
It is the bogie truck adopting steel spring that sleeper beam of the present invention is applicable to two, and steel spring is placed in more than bolster, improves curve passing through crossing ability, reduces manufacture and the maintenance cost of vehicle simultaneously; The heavy mesa structure of sleeper beam of the present invention, sinks to sleeper beam inside by sleeper beam and bogie truck steel spring interface, is strengthened the intensity of heavy stand box body and locating dowel pin mount pad, can meet rigidity and requirement for height that two are steel spring by gusset.
The results showed, structure of the present invention can not only pass through less radius of curve, and cost easy to maintenance is low, and safety is high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is guideway vehicle heavy stand formula sleeper beam structure schematic diagram of the present invention.
Fig. 2 is the exploded view of Fig. 1.
Number in the figure is schematically as follows:
1-lower cover; 2-upper cover plate; 3-breach; 4-box body; 41-pin-and-hole, 5-web; 6-locating dowel pin mount pad; 7-drawing pull bar seat; 8-tie-beam; 9-transverse damper seat; 10-dividing plate, 11-gusset.
Detailed description of the invention
As shown in Figure 1, the present embodiment guideway vehicle heavy stand formula sleeper beam structure, composition comprises: upper cover plate 2, lower cover 1, web 5, it is the corresponding breach 3 of steel spring that lower cover 2 offers with bogie truck two, gap position is fixed with for inserting the uncovered box body 4 that bogie truck two is steel spring upper end, box body 4 is between lower cover 1 and upper cover plate 2, box body 4 coordinates with breach 3 and forms heavy stand structure, it is the pin-and-hole 41 that steel spring locating dowel pin inserts that the top of box body 4 offers for two, it is the locating dowel pin mount pad 6 that steel spring locating dowel pin inserts that the back of box body 4 is fixed with for two, the both sides of sleeper beam are fixed with draw beam draw-bar seat 7.In the present embodiment, in order to improve the intensity of box body 4 and locating dowel pin mount pad 6, between box body 4 and web 5, be fixed with dividing plate 10.Gusset 11 is fixed with between the back of described box body 4 and locating dowel pin mount pad 6.In figure, 8 is tie-beam; 9 is transverse damper seat.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
