Description
Technical field
The present invention relates to rail vehicle technical fields, and in particular to a kind of monoblock type cushioning element on coupler draft gear
Part.
Background technique
Hitch is one of the important device on rail vehicle, and main function is to connect headstock and compartment or compartment and compartment
Be connected together, for mitigate train in operation due to the variation of tractive force or in starting, brake and vehicle phase when the company of shunting hangs
Mutually impact of collision and vibration, vehicle turning hour wheel caused by collision are to cross force, thus mitigate the destruction of body construction,
Improve the stationarity and comfort level of train operation.One group of N part buffer element of existing coupler draft gear point, when being responsible for vehicle launch
Compressed when compressed and vehicle deceleration, not only structure is complicated for this kind of coupler draft gear, and structure is too long, overweight, maintenance replacement fiber crops
It is tired, to expend the time 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 on coupler draft gear
Monoblock type buffer element, it on the basis of guaranteeing certain compression travel, maximum force, buffer capacity and S. E. A.,
It not only has structure simple, convenient for installation and maintenance, and installation maintenance efficiency is higher, also shorter, lighter weight the spy with length
Point develops conducive to entire coupler draft gear to light-weighted direction, while it can also effectively reduce wheel to cross force, avoid occurring
The safety of the accidents such as freight car deraicment, rollover, operation is higher.
In order to solve the above technical problems, technical solution proposed by the present invention are as follows: a kind of entirety 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 is by several metals
Partition and several elastomer cross arrangements form, and are fixedly connected between the metal partion (metp) and the elastomer and form one
It is whole.
The further technical solution of the present invention are as follows: the metal partion (metp) is identical as the shape of elastomer, is direction or back
V-structure from inner core, the bending angle of the V-structure are 100-180 °；When the bending angle of V-structure is 180 °,
Metal partion (metp) and elastomer are 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, and rubber structure is connect by vulcanizing bonding mode with metal partion (metp),
Guarantee that the being completely embedded property between rubber bodies and metal plate is preferable, rubber structure, which has, preferably to be absorbed, slows down train and running
In due to the variation of tractive force or in starting, brake and impact of collision and vibration caused by vehicle mutually collides when the company of shunting hangs
Dynamic, vehicle turning hour wheel is to cross force.
Further, the metal partion (metp) of the inner core side and the quantity of elastomer are no less than one, guarantee cushioning element
The thickness of part meets buffer requirements, can reach the requirement of buffer capacity and maximum force as far as possible in this way, be unlikely to work as
Make buffer full compression when impact force is larger and leads 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.
