Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As shown in Figure 1 to Figure 3, the utility model provides a kind of Undercarriage structure of low-floor rail vehicle, is provided with lower hinge mount pad at the end winding support of underframe.Wherein, the end of underframe comprises edge beam of underframe (not shown) and is positioned at the crossbeam 1 of underframe outermost end, and the two ends of crossbeam 1 are weldingly fixed on edge beam of underframe.
The lower hinge mount pad that the utility model provides comprises buffer beam 5, vertically disposed front mounting plate 2, horizontally disposed upper mounting plate 3 and lower installation board 4, front mounting plate 2 is vertically set on forefront, the parts be connected with articulated structure, front mounting plate 2 is provided with multiple mounting hole 9, the mode of the mode that articulated structure is bolted or riveted joint is fixed on front mounting plate 2, and articulated structure comprises hinged disk etc.Bolt can being adopted to fix and rivet fixing connection mode, the present embodiment between above-mentioned each parts, in order to improve the overall construction intensity of lower hinge mount pad, between each parts, preferably adopting the mode be welded to connect to fix.
Wherein, buffer beam 5 one, the outside of crossbeam 1 is set in parallel in crossbeam 1, in the present embodiment, buffer beam 5 preferably adopts bending beam, to ensure bulk strength and the rigidity of buffer beam 5, the two ends of buffer beam 5 are weldingly fixed on edge beam of underframe or headwall column, are preferably weldingly fixed on edge beam of underframe by buffer beam 5 in the present embodiment.
Front mounting plate 2, upper mounting plate 3, lower installation board 4 are welded and fixed formation box type construction with buffer beam 5, wherein, upper mounting plate 3 extends to crossbeam 1 direction, and its end is welded and fixed with crossbeam 1 and is connected, ensure the structural strength of lower hinge mount pad, ensure the transmission of power.
In order to improve the intensity of whole lower hinge mount pad, between buffer beam 5 and crossbeam 1, multiple tie-beam is set again, in the present embodiment, the tie-beam arranged between buffer beam 5 with crossbeam 1 comprises four longerons 6 vertical with crossbeam 1 and two cant beams be obliquely installed 7, four longerons 6 be arranged in parallel, two cant beams 7 points are located at the both sides of four longerons 6, one end of longeron 6 and cant beam 7 is welded and fixed with buffer beam 5 and is connected, the other end is welded and fixed with crossbeam 1 and is connected, buffer beam 5, longeron 6, cant beam 7 are together with crossbeam 1 assembly welding, and further guarantee power can evenly be transmitted.Because the height of front mount pad 2 is greater than the height of crossbeam 1, therefore, longeron 6 and cant beam 7 one section of being fixedly connected with crossbeam 1 is the section of variable section, forms an approximate step-like transition structure in bottom.
Upper mounting plate 3 is horizontally set on the upper surface of buffer beam 5, front mounting plate 2 and longeron 6, its one end and front mounting plate 2 are welded and fixed, the other end and crossbeam 1 are welded and fixed, be welded and fixed with the upper surface of buffer beam 5 and the upper surface of longeron 6 simultaneously and be connected, upper mounting plate 3 is important force transmission members, is also the parts installed with run-through channel disk simultaneously, should ensures the installation of top run-through channel disk, ensure again that the end of underframe forms general frame structure, guarantee power can evenly be transmitted simultaneously.
In the box type construction that buffer beam 5, front mounting plate 2, upper mounting plate 3 and lower installation board 4 surround, be also provided with multiple gusset 8 for reinforcement, gusset 8 and buffer beam 5, front mounting plate 2, upper mounting plate 3 and lower installation board 4 are welded and fixed.Between every two mounting holes 9 on front mounting plate 2, correspondence arranges a gusset 8, equidistantly be arranged in parallel between multiple gusset 8, ensures to be box type construction around each mounting hole 9, improves the structural strength of lower hinge mount pad further.The end of gusset 8 is inserted into the inside of buffer beam 5, is welded and fixed with buffer beam 5, further to improve the structural strength of lower hinge mount pad.Lower installation board 4 is provided with multiple auxiliary hole 10 to multiple mounting hole 9, the fasteners such as the convenient bolt that installation connects when installing articulated structure.
One end of gusset 8 adopts the mode of grafting welding to be fixedly connected with buffer beam 5, and the other end and front mounting plate 2 are welded to connect, and ensure Joint strenght.Longeron 6 and cant beam 7 adopt degree of lip-rounding beam, and three faces of inside and buffer beam 5 that the end of longeron 6 and cant beam 7 stretches to buffer beam 5 are welded to connect, and ensure Joint strenght.Above-mentioned connection structure can make front mounting plate 2, upper mounting plate 3, lower installation board 4, longeron 6, cant beam 7 form integral structure after welding with buffer beam 5, even if ensure that mount pad lost efficacy under the effect of great power, also articulated structure can not be made to come off, prevent roll-over accident.
For ensureing the installation strength of articulated structure, front mounting plate 2 is formed by plate iron overall processing, installs articulated structure at its facade.The attachment face of front mounting plate 2 carries out overall processing again after end underframe assembly welding completes, to ensure the setting accuracy requirement with articulated structure.
In this implementation column, upper mounting plate 3 welds with crossbeam 1 after welding with buffer beam 5 again, and after end underframe assembly welding completes overall processing upper mounting plate 3 again, to ensure run-through channel disk setting accuracy.
Lower hinge mount pad is designed into the structure that in the underframe of end, formation one is overall by the utility model, eliminate the structures such as draw beam of the prior art, integral structure advantages of simple, lightweight, meet the requirement of vehicle weight-saving, and utilize the underframe integrated carrying longitudinal direction that articulated structure transmits in vehicle operation, transverse direction and vertical force, avoid producing peak force, lower hinge mount pad stressed excessive time, whole end underframe integrated carrying can be passed through, overcome the problem that crackle easily appears in lower hinge mount pad independent in prior art, and then reach the effect strengthening lower hinge mount pad strength and stiffness.
As mentioned above, plan content given by reference to the accompanying drawings, can derive similar technical scheme.In every case be the content not departing from technical solutions of the utility model, any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
