Abstract
The utility model relates to a railway carriage underframe end portion structure which comprises a buffer box, an underframe side beam, a sleeper beam and a floor, wherein the two ends of the buffer box and the sleeper beam are respectively fixedly connected with the underframe side beam, and the buffer box is connected with the floor through deforming plates, wherein the underframe side beam is fixed with the sleeper beam through Huck riveting. As the buffer box is connected with the floor through the deforming plates, the deforming plates can deform when the buffer box transmits longitudinal force, the longitudinal force only can be transmitted to the underframe side beam through the two sides of the buffer box as the deforming plates can generate larger deformation, and then is transmitted to mechanisms, such as the sleeper beam and a bogie connected with the sleeper beam through the underframe side beam, thereby avoiding transmitting the longitudinal force to the sleeper beam directly, and obviously improving the forced performance of a vehicle. The railway carriage underframe end portion structure has the characteristics of light weight, simple structure and reasonable stress. In addition, the sleeper beam is riveted with the underframe side beam rather than a welding structure, which prevents welding from deforming, and guarantees the outer dimension of an assembled underframe.
Description
Technical field
The utility model relates to a kind of passenger train underframe end construction, belongs to rolling stock machinery the manufacturing technology field is installed.
Background technology
The integral solder structure is generally formed by buffer beam, draw beam and sleeper beam in the underframe end of passenger train, and it is an important stressed member of railway passenger train, and its structure directly has influence on the stress performance of vehicle.
The draw beam of common railway passenger vehicle directly and sleeper beam be welded to connect, because the longitudinal force of vehicle is mainly by the draw beam transmission, so draw beam must design very powerfully, draw beam uses section bar in a large number for this reason, cost and weight have been increased, if handle badly, stress concentration can appear in draw beam itself, draw beam and sleeper beam junction, causes the vehicle operating safety problem.
Day bus underframe end sleeper beam and underframe side bar generally all are welded structures, and welding can produce two problems, the one, and welding deformation influences geomery and tolerance that underframe is formed, and the 2nd, the fatigue problem that weld defect causes influences traffic safety.
Summary of the invention
The utility model main purpose is to address the above problem and is not enough, provides a kind of stressed reasonable, simple in structure, lightweight passenger train underframe end construction.
For achieving the above object, the technical solution of the utility model is:
A kind of passenger train underframe end construction, comprise baffle-box, underframe side bar, sleeper beam, floor, captive joint with described underframe side bar respectively in the two ends of described baffle-box and sleeper beam, be connected by deformed plate between described baffle-box and the floor, fix by the Huck rivet between described underframe side bar and the sleeper beam.
The utility model further improves and is that the section form of described deformed plate is the second font, is provided with ripple on two face.
Welding is fixing between described deformed plate and baffle-box and the floor.
Content to sum up, passenger train underframe end construction provided by the utility model has been cancelled traditional draw beam structure, has avoided original day bus draw beam to be directly connected to the structure of growing up of sleeper beam, has alleviated weight.In this structure, be connected by deformed plate between baffle-box and the floor, deformed plate and baffle-box and floor welding are fixing, but do not weld with the underframe side bar, so longitudinal force impassabitity deformed plate passes to the floor until sleeper beam, can only pass to the underframe side bar by the baffle-box both sides, again by the underframe side bar pass to sleeper beam and with mechanism such as sleeper beam bonded assembly bogie truck, longitudinal force is dispersed to both sides underframe side bar, has significantly improved the vehicle stress performance.
In the utility model, be connected by the Huck rivet between sleeper beam and the underframe side bar, non-welded structure has been avoided welding deformation, guaranteed underframe stack-mounted oad, the Huck rivet that adopts when riveting simultaneously also has high strength, anti-loosening, install simply fast, need not characteristics such as maintenance.
This structure is applicable to the passenger train that adopts stainless steel car body, can satisfy the requirement of speed per hour 200Km.
Description of drawings
Fig. 1 the utility model structural representation;
Fig. 2 the utility model deformed plate and baffle-box end and corrugated floor bonded assembly scheme drawing;
Fig. 3 the utility model deformed plate section structure scheme drawing;
The connection structure exploded drawings of sleeper beam and underframe side bar in Fig. 4 the utility model.
As shown in Figures 1 to 4, baffle-box 1, deformed plate 2, underframe side bar 3, sleeper beam 4, floor 5, Huck rivet 6, hitch Connection Block 7, ripple 8.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1, passenger train underframe end construction described in the utility model is installed in two ends, car body underframe bottom, comprises baffle-box 1, deformed plate 2, underframe side bar 3, sleeper beam 4, floor 5, Huck rivet 6.
Wherein, baffle-box 1 can adopt the slab and girder that generally adopts in the prior art, and baffle-box 1 is captiveed joint with the hitch (not shown) by the hitch Connection Block 7 on it, and the two ends of baffle- box 1 and 3 welding of underframe side bar are fixing.As shown in Figure 4, riveted joint between the two ends of sleeper beam 4 and the underframe side bar 3, and adopt a plurality of intensity height, Huck rivet that performance is good to rivet, the welding deformation that has produced when so just having avoided the two ends of sleeper beam 4 and 3 welding of underframe side bar, guarantee underframe stack-mounted oad and tolerance, guaranteed the traffic safety of passenger train.
As shown in Figure 2, be connected by deformed plate 2 between baffle-box 1 and the floor 5, being welding between deformed plate 2 and baffle-box 1 and the floor 5 captives joint, but its two ends are unfixing with underframe side bar 3, so longitudinal force impassabitity deformed plate passes to the floor until sleeper beam, can only pass to the underframe side bar by the baffle-box both sides.
Draw or glancing impact at vehicle, the longitudinal force that baffle-box 1 transmits is passed to deformed plate 2, and deformed plate 2 produces distortion, because deformed plate 2 can produce moderate finite deformation, so deformed plate 2 can't pass through floor 5 to sleeper beam 4 direction transmission with longitudinal force.Longitudinal force is passed to underframe side bar 3 along the both sides of baffle-box 1, again by underframe side bar 3 pass to sleeper beam 4 and with mechanism such as sleeper beam 4 bonded assembly bogie trucks, like this, longitudinal force is dispersed to both sides underframe side bar 3, has significantly improved the vehicle stress performance.
As mentioned above, given in conjunction with the accompanying drawings and embodiments scheme content can derive the similar techniques scheme.In every case be the content that does not break away from technical solutions of the utility model, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical solutions of the utility model according to technical spirit of the present utility model.
