Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail：
Refer to Fig. 1～4, it suitable for EMU two is damping buffer device that the utility model is provided a kind of, bag
Include the top board 1 and lower shoe 2 be arrangeding in parallel up and down；Be triangularly arranged three be arranged between top board 1 and lower shoe 2
Individual locating rod 3, the two-fold volute spring group 18 being sheathed in each locating rod 3, and it is arranged on triangle center location and position
Rod-type cartridge type hydraulic buffer 4 between top board 1 and lower shoe 2.From three point one side principles, using rounded projections arranged
Three locating rods 3, shock absorption buffering mechanism can be made more firm.
As shown in figure 3, the triangular shape of the top board 1, in the outward flange at each angle chamfered is carried out.At three
Spring supporting platform 5 on one is respectively equipped with the position at angle, a upper Positioning holes 6 are equipped with each on spring supporting platform 5, it is described fixed
The upper end of position bar 3 is arranged in the upper Positioning holes 6.Between spring supporting platform 5 in each two and near the edge of the top board 1
Position on open up fixing hole 7 on, the car that buffer unit is fixed on high speed motor car is coordinated by upper fixing hole 7 and bolt
On body base plate.It is provided with one at the center of triangle on the top board 1 and fixes counterbore 8, the rod-type cartridge type hydraulic buffer 4
Upper end be arranged in fixed counterbore 8.
As shown in figure 4, the triangular shape of the lower shoe 2, in the outward flange at each angle chamfered is carried out.At three
Spring supporting platform 9 is respectively equipped with the position at angle, a lower Positioning holes 10 are equipped with each lower spring supporting table 9, it is described
The lower end of locating rod 3 is arranged in the lower Positioning holes 10.Between each two lower spring supporting table 9 and near the lower shoe 2
A lower fixed hole 11 is opened up on the position at edge, is coordinated by lower fixed hole 11 and bolt and buffer unit is fixed on into high quick-action
On the hull bottom plate of car.It is provided with the center of triangle on the lower shoe 2 and fix counterbore 12, the rod-type cartridge type hydraulic pressure
The lower end of shock absorber 4 is arranged in the lower fixed counterbore 12.
As shown in Fig. 2, Fig. 5, each two-fold volute spring group 18 by two height it is different and it is inside and outside be arranged in
Volume volute spring 13 and outer volume volute spring 14 are constituted.The outer volume volute spring 14 is with the involute volute spring 13 coaxially
In locating rod 3 and both direction of rotation is conversely, the outer volume volute spring 14 dextrorotation, the outer volume volute spring 14
It is left-handed.The height of the outer volume volute spring 14 is more than the height of the involute volute spring 13, by the different spiral shell of two length
The mutual fit of rotation spring together, constitutes the different two-fold volute spring group 18 of height, is delayed by two-fold volute spring group 18
Rush the impact and vibrations of vertical direction.The outer volume volute spring 14 and the involute volute spring 13 are made using cold-rolled steel

17, the liquid container 15 is fixed in lower fixed counterbore 12, and the car body connector 17 is arranged in fixed counterbore 8, and convex
Arrange for the top board 1.The rod-type cartridge type hydraulic buffer 4 does negative work to absorb vibrational energy using liquid viscous resistance
Amount, when piston rod is stretched relative to cylinder barrel or compresses motion, internal fluid is produced by throttle orifice during flowing
Raw resistance, dissipation energy；Its entirety is vertically mounted between car body and framework, to decay car body and the vertical of bogie is shaken
It is dynamic, coordinate the load for alleviating each several part, improve the vertical stationarity of car body.
When train bogie and car body are subjected to circuit impact and external environmental interference, and car body heavy duty and underloading are not
Axle weight transfer effect lower body during balance is sidewindered, and yaw etc. acts on the top board 1 on damping buffer device and goes to the bottom
On plate 2, it is undertaken on first on rod-type cartridge type hydraulic buffer 4 so that lower shoe 2 produces downwards displacement, when extraneous load continues
During increase, then the outer volume volute spring 14 for being distributed on three two-fold volute spring groups 18 of surrounding is compressed, and alleviates a part of energy
Amount.Under having emergency circumstances so that rod-type cartridge type hydraulic buffer 4 and outer volume volute spring 14 are all compressed, then contacted
To involute volute spring 13, the involute volute spring 13 and the outer three of volume volute spring 14 carry jointly；External applied load is removed
Then initial position is gradually returned to when disappearing in the case where the rod-type cartridge type hydraulic buffer 4 of bidirectional reciprocating flow damping is acted on.
Obviously, those skilled in the art can carry out various changes and modification without deviating from this reality to the utility model
With new spirit and scope.So, if these modifications of the present utility model and modification belong to the utility model claim
And its within the scope of equivalent technologies, then the utility model is also intended to including including these changes and modification.
