Abstract
An elastic energy-absorbing device for the railcars adopts the compound device of a metal and a soft elastic material to absorb the energy generated by the collision between the railcars. The elastic energy-absorbing device is divided into a metal part and a soft elastic part, wherein the metal part can form a metal plastic deformation thin wall sleeve structure, and the soft elastic part is a lump body that is made from the soft elastic materials and is arranged inside the thin wall sleeve of the metal part. The soft elastic part will absorb the energy generated by the railcars collision when the plastic deformation is generated to some extent by the metal part. The metal part comprises an end cover, a sleeve, an internal post and a lower plate, which are welded as a whole. The end cover adopts multi-guiding structure which is composed of a plurality of neighboring circular arcs. The soft elastic part is composed of a plurality of soft elastic lumps, which are piled and arranged inside the sleeve of the metal part.
Description
Technical field
The utility model belongs to a kind of mechanical absorption device, refers in particular to a kind of used for rail vehicle elasticity energy absorption device, is mainly used in when the macromutation of guideway vehicle generation speed, effectively absorbs impact kinetic energy, reduces the impact between car body and the coupler draft gear; Effectively alleviate the large impact between car body, reduce car body acceleration, guarantee safety by bus, and make car body, coupler and draft gear avoid damaging.
Background technology
Used for rail vehicle elasticity energy absorption device is installed between car body and the coupler draft gear.When the macromutation of vehicle generation speed, spot speed is unequal between the adjacent car body, can produce great impact.Car body, elasticity energy absorption device, coupler draft gear and hitch produce bump each other; coupler draft gear is compressed to absorb impact energy; the tank body of elasticity energy absorption device produces plastic deformation to continue absorbing impact energy until destruction when impulsive force is excessive, and it is a crucial energy-absorbing, the protection link of whole buffer system.The deformation process of tank body was divided into for two stages: at first its neck produces plastic deformation under the guiding of guiding groove; After acquiring a certain degree, distortion produces rupture failure.Therefore the energy of whole absorption is divided into two parts: the energy that energy that plastic deformation absorbs and rupture failure absorb.There is following shortcoming in existing elasticity energy absorption device:
1, energy absorption device is a simple metal spare, has fixing energy absorption, can not adjust to meet the different needs.
2, end cap adopts single guide groove.When car body was subjected to great impact, the tank body of energy absorption device only produced the plastic deformation of an annular along this guiding groove, and deformation tendency is difficult to control, and it is little to absorb energy.
Summary of the invention
The purpose of this utility model is: at the deficiency of existing used for rail vehicle elasticity energy absorption device, a kind of novel track vehicle elasticity energy absorption device is provided, this device is not changing on due function of energy absorption device self and the external structure basis, provide a kind of when car body is subjected to clashing into, have the elasticity energy absorption device of big energy absorption ability and big controllable deforming.
Technology implementation scheme of the present utility model is: utilize the compound elasticity energy-absorbing principle of metal and elastic soft material, the energy that is produced when adopting the compound elasticity energy absorption device of a kind of metal and elastic soft material to absorb the guideway vehicle bump.It is characterized in that: the elasticity energy absorption device is divided into metal partial sum elastic soft part (see figure 1), and wherein said metal part is divided into the thin shelled tubular structure of able to produce metal plastic deformation; The blocks that described elastic soft is partly made for the rubber-like soft material, blocks is installed in the thin-wall barrel of metal part, and partly producing plastic deformation elastic soft part to a certain degree the time at metal will absorb the energy that is produced when guideway vehicle clashes into by plastoelastic deformation.The metal part can comprise end cap, sleeve, inner prop and four parts of lower plate, and as a whole by being welded into, end cap adopts repeatedly guiding structural, and this guiding structural is formed (see figure 2) by a plurality of adjacent circular arcs; The elastic soft part is made up of polylith software piece, and the software piece is stacked together and is installed in the sleeve inner of metal part.
Advantage of the present utility model shows as following four aspects:
1, this elasticity energy absorption device is the endergonic structure of metal plastic deformation and elastic soft material plastoelastic deformation, and big energy-absorbing power can be provided, and can protect car body, the coupler and draft gear of guideway vehicle effectively.
2, this elasticity energy absorption device has adopted repeatedly guiding structural, and the metal part of controllable deforming is bigger, can effectively increase the deflection and the energy-absorbing power of elasticity energy absorption device.
3, the elastic soft piece is installed in the sleeve inner of metal part, does not influence the outward appearance and the installation of elastic element, and can utilize self advantage absorption portion Impact energy of elastic soft material.
4, by adjusting the rigidity and the quantity of elastic soft piece, can adjust the energy absorption of elasticity energy absorption device, to satisfy different needs.
