Description
Technical field
The present invention relates to rail vehicle technical fields, and in particular to a kind of coupler draft gear.
Background technique
Coupler draft gear is one of the important device on rail vehicle, main function be by headstock and compartment or compartment with
Compartment links together, for mitigate train in operation due to the variation of tractive force or in starting, brake and when the company of shunting hangs
Vehicle mutually collide caused by impact of collision and vibration, vehicle turning hour wheel to cross force, to mitigate the broken of body construction
Bad effect, improves the stationarity and comfort level of train operation.One group of N part buffer element of existing coupler draft gear point, is responsible for vehicle
Compressed when compressed and vehicle deceleration when starting, not only structure is complicated for this kind of coupler draft gear, and structure is too long, overweight, dimension
Repair replacement trouble, expend the time it is longer, cause installation maintenance efficiency relatively low.
In addition, for the work more than the turns sweep very littles (about R50m) such as current harbour lorry track and bend
Place, existing coupler and draft gear structure is too long, overweight and existing hitch buffer element structure is not able to satisfy curve half
The driving requirements of diameter very little are easy to produce biggish wheel to cross force, cause freight car deraicment, rollover event.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide a kind of coupler draft gear, it is being protected
On the basis of demonstrate,proving certain compression travel, maximum force, buffer capacity and S. E. A., not only have structure simple, installation
Easy to maintain, installation maintenance efficiency is higher, also has the characteristics that length is shorter, lighter weight, be conducive to entire coupler draft gear to
Light-weighted direction is developed, while it can also effectively reduce wheel to cross force, avoids that the accidents such as freight car deraicment, rollover, fortune occurs
Capable safety is higher.
In order to solve the above technical problems, technical solution proposed by the present invention are as follows: a kind of coupler draft gear, including cushioning element
Part, end carriage link block and hitch, the end carriage link block be equipped with for place buffer element and with buffer element dimensional fits
Putting hole, the hitch side is equipped with slot for blocking the upper and lower bottom surface of buffer element, is equipped in the middle part of the buffer element
Pin hole A, the hitch be equipped with the matching used pin hole B of pin hole A, the buffer element by bolt and hitch it is tight
Close connection；The buffer element includes the symmetrically arranged buffer structure of inner core and inner core two sides, and the buffer structure is by several
Buffer cell rearranges.
As a further improvement of the above technical scheme: being fixedly connected between the buffer cell, each buffer cell packet
Include the metal partion (metp) and an elastomer being fixedly connected.
Further, the buffer cell includes two metal partion (metp)s and an intermediate elastomer, the metal partion (metp)
It is connect by the way of being fixedly connected between the elastomer.
Further, split type connection between the buffer cell, the buffer cell include a metal partion (metp) and one
A elastomer, the metal partion (metp) are attached by the way of fixed or seperated with the elastomer.
Further, the metal partion (metp) is identical as the shape of elastomer, is the V-structure toward and away from inner core,
The bending angle of the V-structure is 100-180 °, when the bending angle of V-structure is 180 °, metal partion (metp) and elastomer
It is board-type structure.
Further, the metal partion (metp) is identical as the shape of elastomer, is the arcuate structure toward and away from inner core,
Transmit the active force between metal partion (metp) and elastomer more smoothly, it is more advantageous when turn sweep is smaller, it will not
Increase the cross force of wheel pair suddenly or excessive.
Further, the metal partion (metp) is identical as the shape of elastomer, is zigzag structure.
Further, the thickness of the elastomer is not less than twice of metal partion (metp) thickness, can satisfy compressed line in this way
The requirement of journey.
Further, the elastomer is rubber structure, has and preferably absorbs, slows down train in operation due to traction
The variation of power or in starting, brake and the company of shunting hang when vehicle mutually collide caused by impact of collision and vibration, vehicle turning
Hour wheel is to cross force.
Further, the quantity of the buffer cell of the inner core side is no less than one, guarantees that the thickness of buffer element is full
Sufficient buffer requirements can reach the requirement of buffer capacity and maximum force as far as possible in this way, be unlikely to when impact force is larger
When make buffer full compression and lead to rigid shock.
Compared with the prior art, the advantages of the present invention are as follows:
1, the present invention uses symmetrically arranged buffer structure, it is ensured that when lorry low speed passes through bend, can effectively reduce wheel
To cross force, generation lorry is avoided to overstep the limit, lorry rollover event；
2, present invention employs the building forms of several metal partion (metp)s and several elastomer cross arrangements, it is ensured that
Under the premise of meeting buffer requirements, can effectively shorten buffer element length and mitigate its weight, single coupler draft gear is in bullet
Property body by full compression state when length be not more than 880mm (from coupler head end face to bicycle beam mounting surface), be particularly suited for port
Road conditions more than the turns sweep very littles (about R50m) such as mouth lorry track and bend, can preferably realize tractive force between compartment
Size and Orientation when vehicle crosses bend will not sudden change it is very big so that wheel increases cross force or excessive suddenly, really
Lorry is avoided to overstep the limit, lorry rollover event；
3, the achievable vehicle of the present invention has lesser turning radius, and in lesser turning radius, buffer element
Buffering effect will not reduce；
4, the configuration of the present invention is simple makes two parts of the buffer element in vehicle deceleration or acceleration using symmetrical structure
Structure function effect is independent of each other, will not be to the rubber of the other side when being able to achieve the rubber layer of rubber bumper side and being compressed
Layer causes to stretch, and can extend the service life of buffer to greatest extent, reliability is higher, and is easily installed, maintenance, repair
Deng operation.
