Abstract
The utility model relates to an inhale sound absorbing floating floor structure belongs to rail train's ground plate structure. Including train chassis, car body side wall, floor, wooden bone or aluminium side, heat preservation insulating layer respectively with train chassis top fixed connection, place the shock pad between floor and wooden bone or aluminium side, inhale sound material and floor below fixed connection, have the sound of inhaling cavity between sound material and the heat preservation insulating layer inhaling, the floor is peripheral to be connected with the extrusion of side wall end position shock pad, the sealed gluey and floor periphery of side wall, the splicing of side wall end position shock pad. The advantage is novel structure, plays the vibration/noise reduction effect through shock pad and the sealed realization floor of gluing simultaneously with the soft contact of automobile body, constitute between floor and chassis and inhale phonetic system all through inhaling sound material and cavity, play and inhale the sound and fall the effect of making an uproar, through vibration/noise reduction with inhale the sound and fall to make an uproar effectively to reduce and come from the car under and car body side wall's vibration and noise, improve noise pollution, improve the train internal environment, improve the interior passenger's of car comfortable ride.
Description
Technical field
This utility model belongs to the floor panel structure of a kind of track train.
Background technology
Train floor structure originally is that floor is directly layered on train underframe, if there being injustice, then pads rubber blanket between；Present floor panel structure is to place wood bone or aluminum side on train underframe in order to levelling, fills the coldproof materials such as heat-preservation cotton in the space got discard；Existing and before train floor structure fail rationally to arrange the way of contact of floor and train, fail Appropriate application underfloor space and fail to consider that reducing internal car noise pollutes, ignore the wheel-rail noise and car body mechanical noise from bottom to top propagated.
Summary of the invention
This utility model provides the floating floor structure of a kind of sound-absorbing damping, and the internal car noise existed to solve current train floor pollutes the problem failing effectively to reduce.
This utility model adopts the technical scheme that: include train underframe, vehicle body side wall, floor, wood bone or aluminum side, heat-insulating and cold layer are fixed above with train underframe respectively is connected, cushion is placed between floor and wood bone or aluminum side, sound absorber is fixing with below floor to be connected, having sound-absorbing cavity, floor periphery and side wall end position cushion squeeze flow between sound absorber and heat-insulating and cold layer, side wall fluid sealant glueds joint with floor periphery, side wall end position cushion.
The utility model has the advantages that novel structure, realize contact soft with car body of floor by cushion with fluid sealant and simultaneously work as damping noise reduction effect；Between floor and underframe, sound-absorbing system is constituted by sound absorber and cavity, play the effect of absorbing sound and lowering noise, can effectively reduce under car by damping noise reduction and absorbing sound and lowering noise and the vibration of vehicle body side wall and noise, improve sound pollution, improve train environment, improve the comfort level by bus of passenger inside the vehicle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Including train underframe 1, vehicle body side wall 2, floor 5, wood bone or aluminum side 4, heat-insulating and cold layer 10 are fixed above with train underframe respectively is connected, cushion 3 is placed between floor 5 and wood bone or aluminum side 4, sound absorber 8 is fixing with below floor 5 to be connected, having sound-absorbing cavity 9, floor 5 periphery and side wall end position cushion 7 squeeze flow between sound absorber 8 and heat-insulating and cold layer 10, side wall fluid sealant 6 glueds joint with floor 5 periphery, side wall end position cushion 7.
Claims (1)
1. the floating floor structure of a sound-absorbing damping, including train underframe, vehicle body side wall, floor, wood bone or aluminum side, heat-insulating and cold layer are fixed above with train underframe respectively is connected, it is characterized in that: place cushion between floor and wood bone or aluminum side, sound absorber is fixing with below floor to be connected, and has sound-absorbing cavity between sound absorber and heat-insulating and cold layer, floor periphery and side wall end position cushion squeeze flow, side wall fluid sealant glueds joint with floor periphery, side wall end position cushion.
