Abstract
The invention relates to a bearing platform type sleeper beam structure for a railway vehicle. The bearing platform type sleeper beam structure comprises an upper cover plate, a lower cover plate and a web. A notch corresponding to a secondary steel spring of a bogie is formed in the lower cover plate. A box which is located between the lower cover plate and upper cover plate and used for being inserted into the upper end of the secondary steel spring is fixed at the notch. The box and the notch coordinate to form a bearing platform structure. A pin hole allowing for insertion of a secondary steel spring positioning pin is formed at the top of the box. A positioning pin mounting seat allowing for insertion of the secondary steel spring positioning pin is fixed at the back of the box. The bearing platform type sleeper beam structure is suitable for the bogie with secondary steel spring, the steel spring is disposed on a swing bolster, vehicle curve negotiation rate is increased, and vehicle production and maintenance cost is lowered. A connector of a sleeper beam and the steel spring of the bogie is submerged into the sleeper beam, and the rigidity and height requirements of the secondary steel spring can be satisfied by strength of the rib plate reinforced bearing platform box and the positioning pin mounting seat.
Description
Technical field
The present invention relates to guideway vehicle heavy stand formula sleeper beam structure, belong to the chassis of rail vehicle technical field.
Background technology
Sleeper beam is one of topmost load member of railroad car bodywork, and it all is passed to the weight of car body on the bogie truck.And form a pair of " traction combination " band motor vehicles bodies or bogie truck benz in orbit with bogie truck.
How increasing along with the outlet of domestic passenger train satisfies some external complicated route requirements, becomes passenger train and manufactures and designs middle problem demanding prompt solution.
Because the national line condition is relatively better, common domestic passenger train structure can't satisfy the radius of curve requirement of some external circuit less, in addition external some state-owned railroads operation ability relatively a little less than, line security is not good, design one good by performance, structure easy to maintenance, safe can effectively promote the developing of foreign market.
The applicant has applied for bolster structure bogie truck under the guideway vehicle in 2012, its secondary suspension adopts air bellow, and the sleeper beam below is provided with corresponding empty spring mount pad.The bogie truck of this form is comparatively widely used at present, and its comfort level is high, and controllable degree is done, but make, maintenance cost is too high, can't 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, and a kind of guideway vehicle heavy stand formula sleeper beam structure is provided.
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 the steel spring upper end, described box body is between lower cover and upper cover plate, described box body cooperates formation heavy stand structure with breach, the top of described box body offers and supplies two to be the pin-and-hole that the steel spring locating dowel pin inserts, and it is the locating dowel pin mount pad that the steel spring locating dowel pin inserts that the back of box body is fixed with for two.
Further, be fixed with dividing plate between described box body and the web.
Further, be fixed with gusset between the back of described box body and the locating dowel pin mount pad.
Further, the both sides of sleeper beam are fixed with the draw beam draw-bar seat.
It is the bogie truck that adopts steel spring that sleeper beam of the present invention is fit to two, and steel spring places more than the bolster, improves the curve passing through crossing ability, reduces simultaneously manufacturing and the maintenance cost of vehicle; The heavy stand formula structure of sleeper beam of the present invention sinks to sleeper beam inside with sleeper beam and bogie truck steel spring interface, strengthens the intensity of heavy stand box body and locating dowel pin mount pad by gusset, and can satisfy two is rigidity and the requirement for height of steel spring.
The results showed, structure of the present invention not only can be passed through less radius of curve, and cost easy to maintenance is low, and is safe.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
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:
The 1-lower cover; The 2-upper cover plate; The 3-breach; The 4-box body; The 41-pin-and-hole, the 5-web; 6-locating dowel pin mount pad; 7-drawing pull bar seat; The 8-tie-beam; 9-transverse damper seat; The 10-dividing plate, the 11-gusset.
The specific embodiment
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 the steel spring upper end, box body 4 is between lower cover 1 and upper cover plate 2, box body 4 cooperates formation heavy stand structure with breach 3, it is the pin-and-hole 41 that the steel spring locating dowel pin inserts that the top of box body 4 offers for two, the back of box body 4 is fixed with and supplies two to be the locating dowel pin mount pad 6 that the steel spring locating dowel pin inserts, and 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, be fixed with dividing plate 10 between box body 4 and the web 5.Be fixed with gusset 11 between the back of described box body 4 and the locating dowel pin mount pad 6.Among the figure, 8 is tie-beam; 9 is the 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 requirement of the present invention.
