Abstract

A kind of 70% low-floor light rail vehicle apron board mounting structure it is characterised in that：Skirtboard upper end is arranged on vehicle body bottom frame side bar by hinged joint, and skirtboard two sides are connected support by spring with car body, setting sound absorber in skirtboard, and car body arranges rubber backstop.The skirtboard of the present invention is attached with vehicle body bottom frame side bar by folding, opens offer center of rotation for skirtboard；Skirtboard is connected with car body by spring, provides support force for skirtboard, skirtboard is being opened in the range of certain angle, the power that spring provides is the power of closing, so, when vehicle passes through curve, bogie produces certain corner with car body, bogie axle head is contacted with skirtboard, and skirtboard is opened slightly, after curve, skirtboard automatically retracts, when overhauling bogie, only skirtboard need to be opened after certain angle, skirtboard can automatically open up；Car body arranges rubber backstop, makes skirtboard lower in off position and car body crust keeps identical；This mounting structure ensure that the clearance control of skirtboard and car body, in 5mm, is placed sound absorber in skirtboard in addition, reduced the propagation outwardly of wheel track noise.

Description

A kind of 70% low-floor light rail vehicle apron board mounting structure
Technical field
The invention belongs to rail vehicle technical field, especially relate to a kind of skirtboard of application on 70% low-floor light rail vehicle Mounting structure.
Background technology
Conventional 70% low-floor light rail vehicle skirtboard is arranged on (as shown in Figure 1) above bogie, there is problems with：（1）Often Secondary vehicle returns storehouse maintenance bogie and is both needed to dismantle skirtboard 1；（2）Between skirtboard 1 and car body 2, gap reaches 100mm, and wheel track noise is direct It is diffused into outside car, affect along thread environment, and unsightly；（3）When vehicle passes through curve, skirtboard exceeds vehicle outer profile size Greatly, easily scratch with circuit two side apparatus.
Content of the invention
It is an object of the invention to provide a kind of 70% low-floor light rail vehicle apron board mounting structure, it is not required to tear open during maintenance bogie Unload skirtboard, reduce the propagation outwardly of wheel track noise, it is to avoid vehicle passes through skirtboard scratch circuit both sides during curve, improve safety With car load aesthetic property.
For achieving the above object, the present invention provides a kind of 70% low-floor light rail vehicle apron board mounting structure, and its feature exists In：Skirtboard upper end is arranged on vehicle body bottom frame side bar by hinged joint, and skirtboard two sides are connected support, skirtboard by spring with car body Interior setting sound absorber, car body arranges rubber backstop.
The skirtboard of the present invention is attached with vehicle body bottom frame side bar by folding, opens offer center of rotation for skirtboard；Skirt Plate is connected with car body by spring, provides support force for skirtboard, and skirtboard is being opened in the range of certain angle, and the power that spring provides is equal For the power closed, so, when vehicle passes through curve, bogie produces certain corner with car body, and bogie axle head and skirtboard connect Touch, skirtboard is opened slightly, after curve, skirtboard automatically retracts, when overhauling bogie, only skirtboard need to be opened certain angle Afterwards, skirtboard can automatically open up；Car body arranges rubber backstop, makes skirtboard lower in off position and car body crust keeps kissing Close；This mounting structure ensure that the clearance control of skirtboard and car body, in 5mm, places sound absorber, fall in skirtboard in addition The propagation outwardly of low wheel track noise.
Brief description
Fig. 1 is conventional 70% low-floor light rail vehicle skirtboard scheme of installation；
Fig. 2 is that sectional view installed by skirtboard of the present invention.
Specific embodiment
With reference to Fig. 2, the specific embodiment of the invention is：Skirtboard 1 upper end is arranged on car body 6 edge beam of underframe by hinged joint 3, Open offer center of rotation for skirtboard.Skirtboard two sides are connected support by spring 8 with car body, provide support force, skirt for skirtboard Plate is being opened in the range of certain angle, and the power that spring provides is the power of closing, so, when vehicle passes through curve, bogie Produce certain corner with car body, bogie axle head 7 is contacted with skirtboard, and skirtboard is opened slightly, and after curve, skirtboard is received automatically Return, when overhauling bogie, only skirtboard need to be opened after certain angle, skirtboard can automatically open up；Rubber is arranged on car body Backstop 4, makes skirtboard lower in off position and car body crust keeps coincideing；This mounting structure ensure that the gap of skirtboard and car body Control in 5mm about, place sound absorber 5 in skirtboard in addition, reduce the propagation outwardly of wheel track noise.
