Abstract
A unit-to-unit damping device of a high-speed multiple-unit train belongs to the technical field of railway carriages and is used for reducing air resistance. The technical scheme includes that the unit-to-unit damping device of a high-speed multiple-unit train consists of lateral wind shields arranged on lateral edges of end walls of units, each lateral wind shield consists of a strip-shaped rubber sac with the shape matching with an arc line of the lateral edge of the end wall of each unit and a rubber sac frame, and the rubber sacs are connected with the end walls of the units through the rubber sac frame. The unit-to-unit damping device is simple in structure and convenient and fast in installation without disassembling the multiple-unit train, can greatly reduce air resistance generated by impacting the end walls of the units via air flows, and then increases running speed of the train.
Description
Technical field
The utility model relates to a kind of being loaded between EMU two vehicles, is used to reduce air resistance, improves the device of running velocity, belongs to the passenger train technical field.
Background technology
The ordinary train running velocity is when 120km/h, and the train air resistance accounts for 40% of total drag, and running velocity is when 160km/h, and air resistance accounts for 70% of total drag.Because train air resistance and train running speed square are directly proportional, therefore, the raising train running speed need reduce the train air resistance.The factor that influences the train air resistance has running velocity, car body nose shape, car body profile, car end structure form etc.
Owing to have the gap between adjacent two vehicle ends of EMU, motor train unit are when operation (speed is greater than 200km/h), and gas shock shunting and disturbance will occur to the car body headwall, air resistance is increased.Therefore, change the version of car body end, alleviate the shunting and the disturbance of air-flow, improving train speed, energy-saving and cost-reducingly having a crucial meaning at this place.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and can effectively reduce gas shock car body headwall and the device for reducing drag between high-speed multiple unit trains of the air resistance that produces.
The alleged problem of the utility model realizes with following technical proposals:
A kind of device for reducing drag between high-speed multiple unit trains, comprise the crosswind retaining that is installed on each car body headwall side in the formation, described crosswind retaining is made up of bar shaped rubber capsule and capsule framework that the camber line of shape and car body headwall side is complementary, and described rubber capsule passes through the capsule framework and is connected with the car body headwall.
Above-mentioned device for reducing drag between high-speed multiple unit trains also comprises the top deflecting plate that is fixed in car body headwall top edge in the formation, the radian of described top deflecting plate is complementary with the radian of car body roof plate and docks with car body roof plate, and dock with the crosswind retaining at its two ends.
Above-mentioned device for reducing drag between high-speed multiple unit trains, the baffle at bottom that also comprises each crosswind retaining below in the formation, the radian of shirt rim is complementary and is fixed on the floor underframe for vehicle by the baffle at bottom support under the radian of described baffle at bottom and the car body, and its upper end keeps off with crosswind and docking.
The utility model installs the crosswind retaining additional in car body headwall both sides, make the car body profile be stream line pattern, has effectively reduced flow perturbation, has reduced air resistance; Crosswind retaining main body is made of the rubber capsule, has not only reduced the slit between the adjacent two car body sidewalls, has reduced air resistance, and can guarantee that vehicle has good curve negotiation ability; The effect of top deflecting plate and baffle at bottom is the distance that as far as possible shortens between adjacent vehicle, reduces the air shunting, thereby reduces air resistance to greatest extent.The utility model is simple in structure, and is easy for installation, quick, do not need motor train unit to separate volume, and can reduce the air resistance that produces because of gas shock car body headwall greatly, improves the running velocity of train.

The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model comprises that top deflecting plate 3 between vehicle, baffle at bottom 2, crosswind keep off 1 three parts.By increasing crosswind retaining 1, make the streamlining of car body profile, reduce flow perturbation and reduce air resistance; By increasing top deflecting plate 3, baffle at bottom 2, shorten the distance between vehicle, reduce the air shunting.
Referring to Fig. 3, Fig. 4, top deflecting plate 3 is welded by aluminium sheet, is installed in roof by bolt.
Referring to Fig. 5～Fig. 7, crosswind retaining 1 is made of capsule framework 4 and rubber capsule 5, and rubber capsule 5 is by being bolted on the capsule framework 4.Capsule framework 4 is installed on the car body headwall by bolt.Behind the coupling of vehicles, the rubber capsule 5 of two crosswind retainings is closely connected, makes the streamlining of car body profile, reduces flow perturbation and reaches the effect that reduces air resistance.
Referring to Fig. 8～Figure 10, baffle at bottom 2 is welded by aluminium section bar, is fixed on the floor underframe for vehicle by baffle at bottom support 6.
Referring to Figure 11, EMU has shortened the distance between vehicle after top deflecting plate, baffle at bottom are installed, and has reduced the air shunting.
But this fairing Fast Installation does not need motor train unit to separate volume.According to circuit operation and test requirements document, can on-the-spot install with bolt, simple in structure, have good reduction air resistance effect and curve negotiation ability, and satisfy the related request of EN12663:2000 " railway applications---railroad car structural requirement ".
