Description
Technical field
The utility model relates to a kind of vehicle body of railway vehicle edge beam of underframe and end pieces connection structure, belongs to rail traffic vehicles body construction technical field.
Background technology
Current domestic railcar stainless steel car body underframe end part generally adopts carbon steel material.As shown in Figure 1, end pieces forms an entirety by two elongated carbon steel side bars, then with the plug welding hole of corrosion-resistant steel edge beam of underframe by reserving on carbon steel side bar, be formed by connecting by plug welding and arc-welding, although this structure can reach the object connecting edge beam of underframe and end pieces, there is gap between end pieces medium-carbon steel side bar and corrosion-resistant steel edge beam of underframe, although add anti-corrosion treatment at these positions, but also can produce corrosion, increase car body manufacturing process and maintenance cost.
Along with the continuous progress to vehicle body of railway vehicle technology, the life-span of body construction is had higher requirement.
Utility model content
The utility model aims to provide a kind of vehicle body of railway vehicle edge beam of underframe and end pieces connection structure, this connection structure optimizes the connection mode of underframe end part and edge beam of underframe in car body, the contact between edge beam of underframe and end pieces carbon steel part can be reduced, reduce the risk of car-body corrosion, reduce the weight of car body, there are good strength and stiffness, for floor underframe for vehicle design provides a kind of connection mode.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of vehicle body of railway vehicle edge beam of underframe and end pieces connection structure, wherein said end pieces comprises sleeper beam lower cover and draw beam upper cover plate; Its constructional feature is, described end pieces to be arranged between two edge beam of underframes and to be directly connected with edge beam of underframe, and described edge beam of underframe is provided with the connecting interface being respectively used to be connected with sleeper beam lower cover with described draw beam upper cover plate.
Be below the technical scheme of further improvement of the utility model:
In order to strengthen the structural strength of underframe main body further, between described end pieces and edge beam of underframe, being provided with reinforcement gusset, reducing the distortion of edge beam of underframe under unwheeling operating mode.
Preferably, between described end pieces and edge beam of underframe, define box connection structure, effectively can increase support strength and the rigidity of underframe.
Above structure, the utility model car body stainless steel car body underframe, primarily of underframe left and right corrosion-resistant steel edge beam of underframe, end pieces, strengthens the compositions such as riser.Edge beam of underframe and end pieces, bear longitudinal force load and vertical force longitudinal loading in vehicle operation, by optimizing end pieces upper and lower cover plates and side bar interface, by corrosion-resistant steel edge beam of underframe and end pieces.
Compared with prior art, the beneficial effects of the utility model are: the utility model corrosion-resistant steel edge beam of underframe and end pieces connection structure Path of Force Transfer directly, optimize end pieces, decrease the contact between corrosion-resistant steel edge beam of underframe and end pieces carbon steel part, reduce the risk of car-body corrosion, reduce the weight of car body, there is good bulk strength and rigidity, decrease carbon steel structure number of packages amount, the force request of current corrosion-resistant steel underframe complex working condition can be met.

Detailed description of the invention
In conjunction with the accompanying drawings and embodiments the utility model is further elaborated for city rail stainless steel car body edge beam of underframe and end pieces connection structure for one below.
A kind of be used for city rail stainless steel car body edge beam of underframe and end pieces connection structure, as Fig. 2 shows: its end piece 1, corrosion-resistant steel edge beam of underframe 2, by the HV weld seam shown in Fig. 2, in Fig. 2, in HY weld seam and Fig. 3, fillet weld couples together, formation underframe agent structure.The longitudinal force that hitch brings is delivered in side bar and whole body construction.
As shown in Figure 3, corrosion-resistant steel edge beam of underframe 2 is provided with the connecting interface with draw beam upper cover plate 1d, end pieces sleeper beam lower cover 1a in end pieces 1, be provided with between end pieces 1 and corrosion-resistant steel edge beam of underframe 2 and strengthen gusset 3, add the support stiffness of end pieces and edge beam of underframe, reduce under unwheeling operating mode, the distortion of edge beam of underframe.
As shown in Figure 5, end pieces 1 by optimize wherein sleeper beam lower cover 1b to achieve with the connection shape of end pieces sleeper beam lower cover 1a be directly connected with edge beam of underframe, the two carbon steel side bars decreased in Fig. 1, optimize draw beam upper cover plate 1c, draw beam upper cover plate 1d in addition, between end pieces 1 and corrosion-resistant steel edge beam of underframe 2, define box-structure, increase underframe support strength and stiffness.
The content that above-described embodiment is illustrated should be understood to these embodiments only for being illustrated more clearly in the utility model, and be not used in restriction scope of the present utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
