Abstract
The utility model discloses a kind of cab door mount structure, comprise rear end side wall outer panel and front end side wall outer panel, rear end side wall outer panel and side wall outer panel top, front end are fixed with top cover side bar, this top cover side bar axially extends to rear end side wall outer panel from front end side wall outer panel along car body, and exceed the top cover side bar that rear end side wall outer panel becomes whole driver's cab, described top cover side bar front end is concordant with front end side wall outer panel, and top cover side bar front end is provided with the chamfering of mating with head-shield radian.It is complicated that the utility model solves cab door mount structure in prior art, and the problem that weld seam quantity is many and dense degree is large, has weld defect and welding deformation is little, the advantage that product design is high.
Description
Technical field
The utility model belongs to rail traffic vehicles body construction technical field, is specifically related to a kind of cab door mount structure being applicable to aluminum alloy light rail car body.
Background technology
As shown in Figure 1, current cab door mount structure mainly adopts the version by door crossbeam 6, A front end side wall outer panel 8 and B rear end side wall outer panel 7 assembly welding.Described door crossbeam 6 adopts the Hybrid connections mode of docking and overlap with B rear end side wall outer panel 7, and door crossbeam 6 adopts the mode of mitered to be connected with A front end side wall outer panel 8.Because door angular zone exists the concentrated problem of stress, in order to improve the intensity of an angular zone, reducing the stress of weld seam near door angle and door angle, often increasing the parts such as an angle gusset at door angular zone.
For this doorframe structure, in order to meet the parts that strength demand increases, all connect by the mode of welding, in the position of front and back ends side wall outer panel and door beam welding, there are many weld seams, weld seam is intensive, and during production, these position heat inputs are large, welding deformation difficulty is controlled, and weldquality can not be guaranteed.
Utility model content
For above-mentioned technical matters, the utility model aims to provide a kind of cab door mount structure, and this doorframe structure weld seam quantity is few, and structure is simple, can farthest reduce weld defect and distortion.
The technical scheme that the utility model is dealt with problems is: a kind of cab door mount structure, comprise rear end side wall outer panel and front end side wall outer panel, rear end side wall outer panel and side wall outer panel top, front end are fixed with top cover side bar, this top cover side bar axially extends to rear end side wall outer panel from front end side wall outer panel along car body, and exceed the top cover side bar that rear end side wall outer panel becomes whole driver's cab, described top cover side bar front end is concordant with front end side wall outer panel, and top cover side bar front end is provided with the chamfering of mating with head-shield radian.
In order to adapt to the installation of the door of more different sizes, the top cover side bar between rear end side wall outer panel and front end side wall outer panel being fixed with needle beam, supporting as installation; Meanwhile, needle beam also can bearing load, can reduce front end side wall outer panel, stress between rear end side wall outer panel and top cover side bar.
In technique scheme, the chamfering of described top cover side bar front end is fixed with and can covers section bar cavity and the shrouding adapting to head-shield radian, bonding for head-shield, prevent glue from entering the die cavity of section bar.
The beneficial effects of the utility model are: simplify cab door mount structure, top cover side bar is axially extended to rear end side wall outer panel from front end side wall outer panel along car body, and exceed the top cover side bar that rear end side wall outer panel becomes whole driver's cab, because top cover side bar itself has enough intensity, an angular zone can be made to have enough intensity, so without the need to using door angle gusset etc. to strengthen parts, also weld seam quantity and dense degree is just consequently reduced, reduce thermal weld stress, effectively reduce weld defect and the welding deformation in cab door crossbeam region, improve product design, also make installation regulate more convenient simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the cab door mount structure schematic diagram of prior art.
Fig. 2 is the utility model cab door mount structure schematic diagram.
Fig. 3 is the utility model needle beam structural representation.
In figure, 1-rear end side wall outer panel, 2-top cover side bar, 3-needle beam, 4-front end side wall outer panel, 5-shrouding, 6-door crossbeam, 7-A rear end side wall outer panel, 8-B front end side wall outer panel.
Detailed description of the invention
As shown in Figure 2 and Figure 3, a kind of cab door mount structure, comprise rear end side wall outer panel 1 and front end side wall outer panel 4, rear end side wall outer panel 1 and front end side wall outer panel 4 top are fixed with top cover side bar 2, this top cover side bar 2 axially extends to rear end side wall outer panel 1 from front end side wall outer panel 4 along car body, and exceeding the top cover side bar that rear end side wall outer panel 1 becomes whole driver's cab, described top cover side bar 2 front end is concordant with front end side wall outer panel 4, and top cover side bar 2 front end is provided with the chamfering of mating with head-shield radian.Described chamfering is fixed with and can covers section bar cavity and the shrouding 5 adapting to head-shield radian, bonding for head-shield, prevent glue from entering the die cavity of section bar.
In order to adapt to the installation of the door of more different sizes, the top cover side bar 2 between rear end side wall outer panel 1 and front end side wall outer panel 4 being fixed with needle beam 3, supporting as installation.
When door assembly mount structure, first by shrouding 5 assembly welding of top cover side bar 2, top cover side bar front end together; Afterwards, by top cover side bar 2 and rear end side wall outer panel 1, front end side wall outer panel 4 assembly welding to together with, top cover side bar 2 front end is concordant with front end side wall outer panel 4 front end.Top cover side bar 2 front end provides support for the bonding of head-shield jointly with front end side wall outer panel 4; Finally, by needle beam 3 assembly welding on the top cover side bar 2 between rear end side wall outer panel 1 and front end side wall outer panel 4.
Claims (3)
