Embodiment
Below, with reference to accompanying drawing, the mode of execution of suspension device for rolling stock involved in the present invention is described as the state that is applied on the railway vehicle.In addition, for the easy to understand structure, Fig. 1 describes as the sectional drawing of the Z-Z line of Fig. 2.
[embodiment 1]
Embodiment's 1 related railway vehicle is inserted between the above-below direction of railway vehicle (omitting diagram) and chassis (omitting diagram) with draft hitch A, constitutes to have: pneumatic spring a, and it is made of upper support portion 1, lower support portion 2 and diaphragm 3; And the stopper b of stacked rubber structure, its array is provided in the below of pneumatic spring a.
Pneumatic spring a constitutes to have: roughly discoideus upper support portion 1, and it is the center with the vertical axis P that is fixed on the supported body such as passenger vehicle (omitting diagram); Lower support portion 2, its ring portion 2B by discoid upper cover part 2A and tubular constitutes; And diaphragm (bellows (bellows)) 3, its by across above-mentioned both 1,2 and the rubber (example of elastic material) of configuration is made, lay across slightly and in the form of a ring.
Stopper b be by main shaft 4 and and main shaft 4 have that plug-in mounting spring section 5 constitutes between ring portion (example of the urceolus) 2B of the vertical axis P of mutually the same (or roughly the same), this spring section 5 have with a plurality of elasitic layer 5A～5C and hard partition wall 5a, 5b with the state of vertical axis P concentric (or roughly concentric) along the alternately laminated stacked rubber structure of diameter inward-outward direction, and, be " Ha " word shape along the observation of the section in the direction of vertical axis P shape.This dispose section is stopper b of " Ha " word shape and the device that pneumatic spring a forms in upright arrangemently up and down, is commonly referred to " the empty mood ば of ユ ニ カ Le ス ト Star パ one type ね ".
Upper support portion 1 forms, utilization is roughly hook-shaped installing ring 14 at the installation peripheral part 1a of its external diameter side place formation with at this section shape that lower face side bolt of peripheral part 1a is installed, and seizes airtight shape and keep side week end, big footpath (the going up flanging part) 3a of diaphragm 3 on both sides by the arms.In addition, the path side of diaphragm 3 week, end (Rolldown hem portion) 3b was with the state along annular projection 9, was installed among the ring portion 2B in the extraterrestrial embedding of the airtight shape of the upside of annular projection 9.Thus, the internal space S of diaphragm 3 and outside airtight shape ground completely cut off, and are constructed such that the compression by air produces buffer function (air cushion).In addition, can adopt following structure, that is, by via with the incorporate shaft sleeve part 1B of the central part of upper support portion 1, with respect to the ejection of carrying out air in the diaphragm 3/charge into, thereby the soft or hard of carrying out air cushion is regulated.
Each side's opposite sex setup unit 6 is installed in this draft hitch A, its make with as the place ahead of vehicle forward direction to (arrow " イ " direction) and rear the relevant spring constant of elasticity to (arrow " ロ " direction), less than with the relevant spring constant of elasticity of left and right directions (direction of arrow " Ha " and " ニ ").Each side's opposite sex setup unit 6 as shown in Figure 1 and Figure 2, constitute, in the position of the fore-and-aft direction (example of " specific direction relevant ") of spring section 5 with the axle center, form make elasitic layer 5A～5C in the footpath relevant with axle center P upwards local disappearance and the wall thickness attenuation n of portion of formation.
Promptly, specifically, by in each elasitic layer 5A, 5B, 5C with vertical axis P be the center fore-and-aft direction about each 45 the degree scopes in and on the diameter inner end, the the 1st～the 3rd wall thickness attenuation portion 11 (n), 12 (n), 13 (n) that make each elasitic layer 5A, the local disappearance of 5B, 5C and form are set with the state that runs through up and down (state that runs through along axle center P direction), thus, constitute described each side opposite sex setting device 6.The radial dimension of each wall thickness attenuation portion 11～13, according to the size in describing accompanying drawing than being about 1/4～1/5 of the radial dimension of elasitic layer 5A～5C, but be not limited to this.In addition, have rubber membrane at the radially inner side of wall thickness attenuation portion 11～13, this is processing antirust for each hard partition wall 5a, 5b and cone axial region 4A and that carry out.That is, the wall thickness attenuation n of portion forms with penetration state attitude up and down in all radially inner side ends of a plurality of elasitic layer 5A～5C, and these the 1st～the 3rd wall thickness attenuation portion 11～13 angular ranges relevant with vertical axis P are set to be equal to each other (90 spend).
In stopper b, by radially partly removing rubber system elasitic layer 5A～5B, promptly, setting makes elasitic layer 5A～5C wall thickness attenuation n of portion that upwards local disappearance forms in the footpath relevant with vertical axis P, thereby the spring constant on this direction relevant with vertical axis P is compared with the position that does not have the wall thickness attenuation n of portion and become lower.Therefore, can make the spring constant of draft hitch A integral body on described direction (in embodiment 1, being fore-and-aft direction) that comprises pneumatic spring a become lower.
That is,, can realize comparing the lower railway vehicle of the spring constant draft hitch A of fore-and-aft direction with left and right directions by the each side's opposite sex setting device 6 that is formed by the wall thickness attenuation n of portion is set.Thus, become the desirable railway vehicle draft hitch A that has carried out improvement as described below, promptly, owing on the fore-and-aft direction that produces shearing force on the pneumatic spring a, set lower spring constant by bend etc., and, on left and right directions, set higher spring constant, so that do not produce inclination in the mode of effective support.
And, because the wall thickness attenuation n of portion is the structure by the local disappearance of elasitic layer 5A～5C is formed, so have the advantage that the spring constant on this direction (fore-and-aft direction) non-linearly increases.That is, under the situation that stopper b is bent upwards in front and back, the wall thickness attenuation n of portion exist during, in scopes, become and do not have identical condition with elasitic layer 5A～5C across each 90 degree of front and back, become lower spring constant.In addition, if front and back are crooked the wall thickness attenuation n of portion is disappeared diametrically, then owing to add the elasticity of the 1st～the 3rd rest layers 15～17 in the diameter outside that is present in the wall thickness attenuation n of portion, so spring constant is corresponding with it and increase.
Promptly, if observing line X relevant with the above-below direction load in " load-displacement curve " shown in Figure 6 will learn, can obtain that spring constant becomes big nonlinear characteristics (rising characteristic) to be bent upwards in front and back to a certain degree along with stopper b, therefore, can obtain the elasticity of softness at crooked initial stage and effective support of midway beginning from bending elasticity the two.。Therefore, can pneumatic spring a easily be out of shape when passing through bend along fore-and-aft direction, make railway vehicle carry out negotiation of bends swimmingly with no crossbeam chassis common.
And, though the ineffective shortcoming of this pneumatic spring a when existing in gas leakage and waiting pneumatic spring a to become air-free state, but, because can obtain if stopper b becomes big and effective supporting nature to be out of shape then spring constant to a certain degree on fore-and-aft direction, thus even have that on the fore-and-aft direction unexpected heavy load of effect also can access good suspension property the advantage that can stably carry out negotiation of bends.In addition, the change point of this spring constant hour moves to low load side in the radial width of the wall thickness attenuation n of portion, the radial width of the wall thickness attenuation n of portion greatly the time to the high capacity side shifting.
In addition, in each side that this suspension device for rolling stock A is had opposite sex setting device 6, also have the effect and the effect that can produce better suspension property at the load of above-below direction.That is,, under non-loaded or underloaded state, as shown in Figure 3,,, the 1st～the 3rd wall thickness attenuation portion 11～13 exists so keeping former states or almost keep former state because stopper b is not crooked or crooked hardly on above-below direction as Fig. 3～shown in Figure 5.
If effect load up and down to a certain degree, then as shown in Figure 4, the part that each elasitic layer 5A～5C and cone axial region 4A etc. are present in its diameter inboard relative to and move downwards, but, owing to be " Ha " word oblique structure, compare with the two ends up and down that are pulled, the restricted intermediate portion up and down of above-below direction distortion radially protrudes distortion (dilatancy).Thus, increase and part (the cone axial region 4A or the first hard partition wall 5a etc.) butt of beginning and diameter inboard from intermediate portion radial dimension up and down.Promptly, because the elasticity of rest layers 15,16,17 begins subparticipation, so shown in the line Y relevant, roughly be linear changing condition distortion before this in " load-displacement curve " as shown in Figure 6, change starting point s place spring constant at spring constant and begin increase with the above-below direction load.
In addition, if the load of above-below direction continues to increase, then each wall thickness attenuation portion 11～13 continues to reduce gradually, at last as shown in Figure 5, wall thickness attenuation portion disappears, each rest layers 15,16,17 across its up and down and with part (cone axial region 4A, the first hard partition wall 5a, the second hard partition wall 5b) butt (spring constant among the line Y changes end point e) of inboard.Further increasing in contrast to this under the situation of above-below direction load, according to maximum spring constant and displacement increases (part that the spring constant among the line of reference Y changes the heavy load side of end point e).
As described above, the wall thickness attenuation n of portion is at the spring constant as stopper b of above-below direction load, the rising characteristic that obtain non-linearly along with the increase of above-below direction load, promptly increases progressively.Thus, can realize having the railway vehicle draft hitch A of excellent stopper b, this stopper b when empty wagons～when the regulation number is ridden, act on flexibly, when when full or above full number, riding, effectively support, that is, when sensation is taken in improvement, can also bear heavy load.
And, as the unit that is used for this, only make the local diametrically disappearance of elasitic layer 5A～5C among the stopper b and simple and do not need the constituting component of periphery is carried out all transformations and rationally.Thus, the advantage on using is a lot, promptly both economical, and easily subsequent installation is medium at existing machine.
In addition, though the diagram of omission, but under the situation that is applied to truck (automobile), in order to act on flexibly usually, but support and bear among the stronger deceleration G that causes bringing to a halt, also can be formed on the place ahead relevant and the wall thickness attenuation n of portion is set and makes the spring constant in the place ahead be set at the suspension device for rolling stock A of the state of non-linear rising with vertical axis P.
[other embodiments]
The wall thickness attenuation n of portion only is arranged on the 1st elasitic layer 5A, perhaps is arranged on the 2nd and the 3rd elasitic layer 5B, the 5C structure on the two, in addition, also can not be penetratingly formed along the vertical direction.In addition, its setting can be corresponding with desired condition and at random change, such as only being arranged at the place ahead or rear, perhaps in the scopes of the scopes of 60 degree relevant with axle center P or 120 degree.
Stopper b also can be as shown in Figure 7, has each side's opposite sex setup unit 6 of the structure of the diameter outboard end that each wall thickness attenuation portion 11～13 (n) is formed at each elasitic layer 5A～5C.
