Abstract
The present invention relates to a kind of draw-gear of rail vehicle with elastic bolster guide function, with vertically arranged pressing plate and backboard, set and have elastic component between pressing plate and backboard, backboard is used to be fixed on side of the bogie towards sleeper beam, the lateral surface of pressing plate is provided with friction plate, for propping up the sleeper beam of rail vehicle from longitudinal direction.Rail vehicle is during operation, tractive force is passed to rail vehicle by the draw-gear of the present invention ensures the normal operation of rail vehicle, due to being provided with elastic original paper in elastic bolster guide, rail vehicle can be effectively eliminated to start and caused impact of collision in braking procedure, the comfortableness and security of raising passenger's seating.Often contacted simultaneously because vehicle body bottom frame and elastic bolster guide are elasticity, can effectively suppress snake operation of the rail vehicle on straight way, it is ensured that the security of rail vehicle.
Description
Technical field
The present invention is to meet the tendency of to transmit longitudinal traction between vehicle body of railway vehicle and bogie and limit vehicle in straight line
A kind of elastic bolster guide of upper snake operation, belongs between a kind of rail vehicle truck and car body and draws and limit vehicle hunting
Technical field.
Background technology
In the design process of rail vehicle, typically transmitting longitudinal force by center draw-gear ensures vehicle along laying
Rail running, currently used center draw-gear have traction rubber metal pad traction, single traction rod traction and double drawing pull bars
Three kinds of traction.These three common draw-gears are arranged on bogie pivot center position and are connected with car body sleeper beam or draw beam, lead
Draw rail vehicle along rail running.Traditional traction device is complicated, and current check is difficult in maintenance, while by rail vehicle
Lower space limits, and can sacrifice the vertical comfortableness of rail vehicle.
Due to the characteristic of rail vehicle orbiting, rail vehicle can produce hunting when rectilinear orbit travels,
At present typically by setting backstop and parameter optimization to suppress the hunting of vehicle.
The content of the invention
The technical problems to be solved by the invention are to overcome the disadvantages mentioned above of prior art, there is provided a kind of rail vehicle band
The draw-gear of elastic bolster guide function.
In order to solve the above technical problems, draw-gear of the rail vehicle provided by the invention with elastic bolster guide function, its
It is characterised by：With vertically arranged pressing plate and backboard, set and have elastic component between the pressing plate and backboard, the backboard is used
In being fixed on side of the bogie towards sleeper beam, the lateral surface of the pressing plate is provided with friction plate, for being propped up from longitudinal direction
The sleeper beam of rail vehicle.
The present invention also has feature further below：
1st, the center of the pressing plate is raised to backboard, and projection is provided with screw, the backboard center drilling, spiral shell is screwed in by bolt
Realize the compression of flexible member in hole.
2nd, the backing plate for carrying bolt is prevented in the backboard center drilling.
3rd, the flexible member is made up of flexible polyurethane material, tartan or non-metallic composite material.
For rail vehicle during operation, tractive force is passed to rail vehicle by draw-gear of the invention ensures track
The normal operation of vehicle, due to being provided with elastic original paper in elastic bolster guide, it can effectively eliminate rail vehicle and start and braking
Caused impact of collision in journey, improve comfortableness and security that passenger takes.Simultaneously because vehicle body bottom frame and elastic bolster guide are
What elasticity often contacted, it can effectively suppress snake operation of the rail vehicle on straight way, it is ensured that the security of rail vehicle.
To sum up, the present invention can either meet the transmission of rail vehicle longitudinal traction, and can limit rail vehicle straight
Hunting when line travels, draw-gear is simple in construction feasible, and current check is easy to maintenance, while solves rail vehicle and lead
Draw with hunting problem, save human and material resources, not only increase the comfortableness of rail vehicle, and reduce enterprise
Manufacturing cost, kill two birds with one stone.

Embodiment
As shown in figure 1, draw-gear of the present embodiment rail vehicle with elastic bolster guide function, has vertically arranged pressing plate
2 and backboard 4, set between pressing plate 2 and backboard 4 and have elastic component 3, backboard 4 is used to be fixed on side of the bogie towards sleeper beam,
The lateral surface of pressing plate 2 is provided with friction plate 1, for propping up the sleeper beam of rail vehicle from longitudinal direction.The center of pressing plate 2 is to backboard
Projection, projection are provided with screw, and backboard center drilling is simultaneously interior to set backing plate 5, and screwing in screw by interior hexagonal compression bolt 6 realizes bullet
The compression of property element.
Friction plate 1 is using synthetic materials such as the good nylon of anti-wear performance, aramid fiber enhancing composites.Pressing plate 2, backboard 4, pad
Plate 5 is manufactured using the steel such as 45# steel, Q345 steel or stainless steel and other metal materials.Flexible member 3 is flexible polyurethane
Material, tartan or non-metallic composite material are made.Interior hexagonal compression bolt 6 is it is contemplated that press the standards 8.8 of ISO 10642
Level requires production, material selection 45# steel, does modifier treatment, surface blackening or plating Geomet processing.
The height of whole elastic bolster guide can be compressed by interior hexagonal compression bolt 6, facilitates the installation of sleeper beam.Consider simultaneously
To safety factor, h rigid backstop gap is set in the inside of elastic bolster guide according to the structural parameters of rail vehicle, works as compression body
When 3 failures or damage, rigid backstop h=0, it can be ensured that the rolling stock section that reaches of rail vehicle safety is more changed jobs again.
The installation method of the present embodiment draw-gear, step are as follows：
Step 1, four draw-gears are symmetrically fixed on bogie 9, specifically, by bolt by the backboard of draw-gear 7
It is fixed on side of the bogie towards sleeper beam；
Step 2, interior hexagonal compression bolt head is passed through into backboard center drilling and screwed in the raised screw of pressing plate, pressing plate and the back of the body
Plate compression elastic element, the spacing of two relative draw-gears is set to be not less than the width of sleeper beam；
It is on spring 10 that step 3, sleeper beam 8, which are put between draw-gear 7 and fallen two,；
Hexagonal compression bolt in step 4, release, the elastic force of flexible member act in a longitudinal direction through pressing plate and friction plate successively
In sleeper beam, sleeper beam is set to be clamped in a longitudinal direction by draw-gear.
In addition to the implementation, the present invention can also have other embodiment.It is all to use equivalent substitution or equivalent transformation shape
Into technical scheme, all fall within the protection domains of application claims.
