Description
Technical field
The present invention relates to rail vehicle technical fields, and in particular to a kind of split type cushioning element on coupler draft gear
Part.
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, is not able to satisfy sweep driving requirements, is easy to produce biggish
Wheel causes freight car deraicment, rollover event to cross force.
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 on coupler draft gear
Split type buffer element, on the basis of guaranteeing certain compression travel, maximum force, buffer capacity and S. E. A., it
Not only have structure simple, convenient for installation and maintenance, installation maintenance efficiency is higher, also have the characteristics that length is shorter, lighter weight,
Develop conducive to entire coupler draft gear to light-weighted direction, while it can also effectively reduce wheel to cross force, avoids that goods occurs
Accidents, the safeties of operation such as vehicle derailing, rollover are higher.
In order to solve the above technical problems, technical solution proposed by the present invention are as follows: a kind of fission on coupler draft gear
Formula buffer element, including buffer element ontology, the middle part of buffer element ontology are equipped with the mounting hole for being connected and fixed with hitch,
The buffer element ontology includes the symmetrically arranged buffer structure of inner core and inner core two sides, and the buffer structure includes that several are slow
Unit is rushed, is attached between each buffer cell using split type connecting method.
As a further improvement of the above technical scheme: the buffer cell includes two metal partion (metp)s and intermediate one
Elastomer is connected by the way of being fixedly connected between the metal partion (metp) and the elastomer.
Further, the buffer cell includes metal partion (metp) and elastomer, and the metal partion (metp) is adopted with the elastomer
It is attached with the mode of fixed mode or fission.
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.
Further, the metal partion (metp) is identical as the shape of elastomer, is zigzag structure, this structure is convenient for metal
The multi-direction transmitting of active force between plate and elastomer, convenient for guaranteeing that buffer element is still with higher when bearing compared with big load
Reliability.
Further, the face shape of the left and right of the metal partion (metp) two is identical or not identical, wherein the structure on left and right two sides
For any one of V-structure, arcuate structure, zigzag structure, two or three of combination；The left and right of the elastomer two
Face shape is identical or not identical, and wherein the structure on left and right two sides is V-structure, arcuate structure, any one in zigzag structure
Kind, two or three of combination.
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.
