The content of the invention
For example, the air cylinder device 100 described in Japanese Unexamined Patent Publication 2011-201332 publications shown in Fig. 7, stops in motor
Played a role during only as damping force variable shock absorber, it possesses：Cylinder body 101, it connects with the side in vehicle body and bogie
Connect；Piston 102, it is sliding freely inserted in cylinder body 101；Piston rod 103, it inserts in cylinder body 101 and connected with piston 102
Connect, and be connected with the opposing party in vehicle body and bogie；Side room R1 and compression side room R2 are extended, it is led in cylinder body 101
Cross what piston 102 was marked off；Storage tank T；First switch valve 105, it is arranged at connection elongation side room R1 and compression side room R2's
The midway of first passage 104；Second switch valve 107, it is arranged at connection compression side room R2 and storage tank T second channel 106
Midway；Passing away 108, elongation side room R1 is connected to storage tank T by it；Variable overflow valve 109, it is arranged at passing away
108 midways and it can change cracking pressure；Suction passage 110, it only allows liquid to be flowed from storage tank T towards compression side room R2；
And rectification passage 111, it only allows liquid to be flowed from compression side room R2 towards elongation side room R1.
According to above-mentioned composition, the company of second channel 106 is allowed by second switch valve 107 during motor stops
It is logical, first passage 104 is blocked by first switch valve 105 in the case of, due to when air cylinder device 100 extends, by piston
Liquid in the elongation side room R1 of 102 compressions is pushed variable overflow valve 109 open and discharged to storage tank T, and therefore, air cylinder device 100 is sent out
Wave the damping force of resistance elongation.But, when air cylinder device 100 is in the shape that second channel 106 is connected, first passage 104 is blocked
When being shunk under state, because the liquid in compression side room R2 flows out via second channel 106 to storage tank T, and liquid is via rectification
Passage 111 is supplied in elongation side room R1, and therefore, air cylinder device 100 is shunk without resistance.
In addition, allowing first passage 104 to connect, opened by second by first switch valve 105 during motor stops
In the case that pass valve 107 blocks second channel 106, when air cylinder device 100 is shunk, due to what is compressed by piston 102

When vehicle body is moved towards right and also moved relative to bogie towards right, air cylinder device 100 shrinks, so as to play resistance
The damping force of the contraction simultaneously suppresses movement of the vehicle body towards right, further, it is possible to the valve opening pressure by adjusting variable overflow valve 109
Power and change the damping force.But, under the same conditions, moved in bogie than vehicle body more quickly toward right, vehicle body direction
Right move but relative to bogie towards left move when, air cylinder device 100 understand be extended without resistance, so as to will not promote
Enter movement of the vehicle body towards right.
That is, according to above-mentioned air cylinder device 100, as long as by being used when performing active control regular based on suspension control
Computing come obtain resistance air cylinder device 100 elongation power (thrust of shrinkage direction) and resistance contraction power (prolonging direction
Thrust), and control the cracking pressure of variable overflow valve 109 to enable air cylinder device 100 to play the power, though according to
This mode is set, also will not when the direction of the direction of the speed of vehicle body and vehicle body and the relative velocity of bogie is inconsistent,
Make body vibrations because of the vibration of bogie.
Moreover, in the existing shock absorber device for railway vehicle of semi- active control is performed by this way, although as long as
One is only installed between vehicle body and a bogie as the air cylinder device 100 of damping force variable shock absorber can just suppress vehicle body
Side-to-side vibrations, and suppress the vibration increase of vehicle body, still, needed in an air cylinder device 100 (damper) as switch

The compression area of the compression side room R2 sides of plug 3 is multiplied by the value obtained by compression side room R2 pressure.Therefore, because being intended to by above-mentioned
First damper DL and the second damper DR obtain the power equal with existing air cylinder device 100, and by making relative to displacement
The flow of amount is identical and when obtaining equal response, the cross-sectional area of piston 3 can be set to existing 1/2nd, because
This, can make the internal diameter of cylinder body 1 be less than existing internal diameter.Then, the internal-and external diameter of the external diameter of cylinder body 1 and outer shell 2 is respectively less than existing
Value, so as to minimize the first damper DL and the second damper DR.Accordingly, because the first damper DL and the second damping
Device DR can suppress fee of material and reduce cost to be small-sized, also, set on a bogie the first damper DL and
Second damper DR, also it is easy to ensure that installing space.
Also, as described above, in the case where air cylinder device 100 is one-way flow type, the pressure in elongation side room R1 becomes
It is high.Thus, because when the pressure in elongation side room R1 is uprised, the direction of the pressure towards upper ejection lid 112 plays a role, because
This, air cylinder device 100 has the outer shell for covering the periphery of cylinder body 101, forms storage tank T's between the outer shell and cylinder body 101
In the case of, draw direction is applied to the junction surface of outer shell, the junction surface of the outer shell and top cover 112 and outer shell and bottom 113
Load.Therefore, turn into elongation side room R1 in the air cylinder device 100 of high pressure, it is necessary to by the drawing at outer shell and the junction surface of outer shell
Stretch intensity to be set to that the intensity of above-mentioned load-carrying can be born, thus it requires higher-strength.
In contrast, in the above-mentioned first damper DL and the second damper DR of present embodiment, due to elongation side room
R1 pressure is pressure of storage tank and approximately fixed, and will not be uprised, therefore, for outer shell 2, the stretching at the junction surface of outer shell 2
The requirement reduction of intensity.Therefore, it is possible to reduce the thickness of outer shell 2 or form outer shell 2 using synthetic resin, so as to Enough System
Make the outer shell 2 of cheap and light weight.In addition, in the case of by welding outer shell 2 being engaged with top cover 5 and bottom 6, by
Weld job is easily carried out in requiring performance relatively low, also, their engagement can also be carried out by split ring or press-in etc.,
So as to use simple linking method.
Also, in above-mentioned air cylinder device 100, as noted previously, as turning into high pressure in elongation side room R1, therefore, inciting somebody to action
, it is necessary to by the sealing ring component 114 of the low-pressure side as atmospheric side and as cylinder body in the case of the periphery of piston rod 103 is sealed
The on high-tension side both sides of sealing ring component 115 of 101 sides are set to series connection.Because the on high-tension side sealing ring component 115 bears to stretch
Long side room R1 pressure and compressed so that internal diameter reduce, therefore, with above-mentioned on high-tension side sealing ring component 115 by strength
By the tendency to piston rod 103.Therefore, on high-tension side sealing ring component 115 is easily worn, so that replacement frequency is higher.
In contrast, in the above-mentioned first damper DL and the second damper DR of present embodiment, as noted previously, as
High pressure will not be turned into by extending the pressure in the R1 of side room, therefore, removed on high-tension side sealing ring component 115, only set low-pressure side
Sealing ring component 50.Therefore, it is possible to reduce the number of components so as to reduce cost, and piston rod 4 can be made relative to cylinder
The action of body 1 is good.
By above-mentioned reasons, in the first damper DL, the second damper DR and air cylinder device 100, will be except
When part outside the valve type of electric drive valve etc. is as main body, compared with the main body of air cylinder device 100, can extraordinarily it drop
The manufacturing cost of low first damper DL and the second damper DR main body.Therefore, even if every bogie W needs two dampings
Device (the first damper DL and the second damper DR), but compared with possessing the shock absorber device for railway vehicle of air cylinder device 100,
Shock absorber device for railway vehicle S according to possessing above-mentioned first damper DL and the second damper DR can also reduce every steering
Frame W cost.But, the first paired damper DL and the second damper DR composition are not limited to above-mentioned composition, can also
Suitably changed.Represent to represent first in the first damper DL and the second damper DR the first variation, Fig. 5 in Fig. 4
Damper DL and the second damper DR the second variation.
The damper D1 that the first variation shown in Fig. 4 is related to possesses：Cylinder body 1；Storage tank T, it is arranged at outside the cylinder body 1
Portion；Piston 3, it is inserted in cylinder body 1 in the way of it can move and elongation side room R1 will be divided into cylinder body 1 and compression side room
R2；Piston rod 4, it links with the piston 3 and stretched out through elongation side room R1 from cylinder body 1；Hole (communicating passage) 3a, it will
Elongation side room R1 is connected with compression side room R1；Suction passage 8, it only allows liquid from storage tank T towards compression side room R2 flowing；
Damp channel 7, compression side room R2 is connected to storage tank T by it；And, variable overflow valve (variable damper valve) 70, it is arranged at
On the damp channel 7.Moreover, above-mentioned hole 3a is arranged to will not occur undergauge.
According to above-mentioned composition, damper D1 is the damper for the pressure action type that damping force is only played when shrinking, so that
Damping force is not played in elongation and is extended without resistance.In addition, the regulation of the cracking pressure by variable overflow valve 70, can
Damping force when damper D1 is shunk is set to variable.Therefore, as long as a bogie W with the reverse side in left and right
Formula is installed the damper D1 of a pair above-mentioned pressure action types or damper D1 and the first damper DL is reversely installed with left and right
Or second damper DR any one, then can be by damper D1, D1 or damper D1 and the first damper DL or second
Damper DR damping force is set to variable, so as to suppress the oscillation crosswise of automobile body B, and can suppress the vibration increase of automobile body B.
Moreover, in the case where shock absorber device for railway vehicle S utilizes above-mentioned damper D1, the electricity needed for every damper
Driving valve quantity be also only as variable damper valve variable overflow valve 70 this.Therefore, even if every bogie needs
A pair of (two) dampers, also can be set to two by the quantity of the electric drive valve needed for every bogie W, can be with existing skill
Art is compared and cut down.That is, in the shock absorber device for railway vehicle S using above-mentioned damper D1, electric drive can also be reduced
The quantity of dynamic valve, so as to reduce cost.Even if moreover, the first damper DL of above-mentioned pressure action type, the second damper DR with
And in elongation side room R1 to produce suction bad by damper D1, but due to not playing elongate sides damping force, even if thus hole 1a, 3a with
Somewhat the mode of undergauge and playing a role also has no problem.
In addition, when damper D1 shrinks, the liquid in the compression side room R2 of diminution is moved into the elongation side room R1 of expansion
It is dynamic, so that both pressure becomes equal, also, the liquid of the amount corresponding with entering the volume of the piston rod in cylinder body 1
Push variable overflow valve 70 open and moved towards storage tank T.Therefore, the pressure in cylinder body 1 turns into the cracking pressure of variable overflow valve 70,
Power produced by damper D1 turns into above-mentioned pressure and is multiplied by the elongation side room R1 sides of piston 3 and the compression area of compression side room R2 sides
Value obtained by difference.In above-mentioned damper D1, because the pressure for extending side room R1 turns into high pressure, therefore, while it is desirable in piston
The periphery of bar 4 sets on high-tension side sealing ring component 51, still, due to that can make elongation side room R1 and compression side room R2 pressure
It is identical, therefore, it is possible to omit the seal 30 (Fig. 3) of the periphery of piston 3.
Moreover, being intended to obtain the power equal with existing air cylinder device 100 by above-mentioned damper D1, and obtain equal
Response when, the cross-sectional area of piston 3 can be set to be less than existing cross-sectional area.Because：In the feelings so constituted
Under condition, as long as making the compression face product moment of the both sides of piston 3 same as the prior art, the compression area of elongation side room R1 sides is pressure
Less than/2nd of the compression area of contracting side room R2 sides also may be used.Thus, when reducing the cross-sectional area of piston 3, it can reduce
The internal diameter of cylinder body 1, and the external diameter of cylinder body 1 and the internal-and external diameter of outer shell 2 can be also reduced, therefore, it is possible to make damper D1 small
Type, and cost can be reduced.
Further, since the passage that side room R1 is connected with storage tank T need not will be extended in above-mentioned damper D1, therefore,
Can not be in the periphery of cylinder body 1 using the formation storage tank T of outer shell 2, and storage tank T is arranged side by side with cylinder body 1.
Then, the damper D2 that the second variation shown in Fig. 5 is related to possesses：Cylinder body 1；Outer shell 2, it is in the cylinder body 1
Periphery forms storage tank T；Piston 3, it is inserted in cylinder body 1 in the way of it can move and elongation side room R1 will be divided into cylinder body 1
With compression side room R2；Piston rod 4, it links with the piston 3 and stretched out through elongation side room R1 from cylinder body 1；Piston channel
3b, it only allows liquid from compression side room R2 towards elongation side room R1 flowing；Suction passage 8, it only allows liquid from storage tank T
Towards compression side room R2 flowing；Damp channel 9, elongation side room R1 is connected to storage tank T by it；And, variable overflow valve is (variable
Orifice valve) 90, it is arranged on the damp channel 9.Same with above-mentioned variable overflow valve 70, the variable overflow valve 90 is set
In the midway of damp channel 9, and it is configured to, has：The valve body 90a that is switched to damp channel 9, with by damp channel 9
The mode of blocking applies the spring 90b of active force to valve body 90a and the ratio of resistance spring 90b thrust is produced when being powered
Solenoid 90c.In addition, the elongation side room R1 of the upstream as damp channel 9 pressure is made in the way of opening damp channel 9
For valve body 90a.
According to above-mentioned composition, damper D2 is the damper for the stretching action formula that damping force is only played in elongation, so that
Damping force is not played when shrinking and is shunk without resistance.In addition, the regulation of the cracking pressure by variable overflow valve 90, can
Damping force when damper D2 is extended is set to variable.Therefore, as long as being installed for a bogie W in the reverse mode in left and right
The damper D2 and pressure of stretching action formula are installed in the damper D2 of a pair above-mentioned stretching action formulas or left and right identical direction
The first damper DL, the second damper DR or the damper D1 of action type, then can change damper D2 damping force or
Damper D2 and the first damper DL, the second damper DR or damper D1 damping force, so as to suppress the horizontal stroke of automobile body B
To vibration, and the vibration increase of automobile body B can be suppressed.Left and right identical direction mounting shock absorber refers to：It is installed as,
When automobile body B is relative to bogie W transverse shiftings so that two damper simultaneous retractables.
Moreover, in the case where shock absorber device for railway vehicle S utilizes above-mentioned damper D2, the electricity needed for every damper
Driving valve quantity be also only as variable damper valve variable overflow valve 90 this.Therefore, even if every bogie needs
A pair of (two) dampers, also can be set to two by the quantity of the electric drive valve needed for every bogie W, so as to showing
There is technology to compare and cut down.That is, in the shock absorber device for railway vehicle S using above-mentioned damper D2, it can also reduce
The quantity of electric drive valve, so as to reduce cost.
In addition, in the present embodiment, in order to play damping force and make the damping force variable, in the first damper DL,
Variable damper valve is set in two damper DR, damper D1 and damper D2, and can as this by the use of variable overflow valve 70,90
Mutative damp valve.The variable overflow valve 70,90 is the magnetic valve with proportional solenoid 70c, 90c, and is occurring what can not be powered
During failure, it is fixed to the pressure-control valve of maximum as cracking pressure and plays a role.Therefore, in failure, the first damping
Device DL, the second damper DR, damper D1 and damper D2 damping force are uniquely determined relative to piston speed.In addition,
Variable damper valve can also be the motor-driven valve for example using motor, for playing damping force and enabling the composition of damping force variable
It is enough suitably to be changed.The variation of variable damper valve is shown in Fig. 6.In addition, although the adaptive damping that the variation is related to
Valve 71, which will be arranged at, to be compressed on the damp channels 7 that are connected with storage tank T of side room R2, but naturally it is also possible to by the adaptive damping
Valve 71, which is arranged at, will extend on the damp channel 9 that side room R1 is connected with storage tank T to replace variable overflow valve 90.
Variable damper valve 71 shown in Fig. 6 is configured to, and is had：It is arranged at the first overflow valve of the midway of damp channel 7
72 and it is arranged in series in the second overflow valve 73 and switch valve 74 on the subaisle 7a around the first overflow valve 72.First overflows
Valve 72 is flowed with the valve body 72a for switching damp channel 7, to apply active force to valve body 72a to block damp channel 7
Spring 72b, also, as upstream compression side room R2 (Fig. 3) pressure by make damp channel 7 open in the way of act on valve
On body 72a.In addition, the second overflow valve 73 has the valve body 73a switched to subaisle 7a and made with applying to valve body 73a
Firmly so as to block subaisle 7a spring 73b, also, turn into the compression side room R2 of upstream pressure so that subaisle 7a is opened
Mode act on valve body 73a.In addition, switch valve 74 is arranged at the downstream of the second overflow valve 73, and have：Valve body
74a, it is located at the blocking position blocked by the subaisle 7a communicating positions connected or by subaisle 7a；Spring 74b, it is to valve
Body 74a applies active force so that valve body 74a is located at communicating position；Proportional solenoid 74c, its resistance spring 74b when being powered
Active force by valve body 74a so that switch to blocking position；And push rod 74d, it prolongs from valve body 74a towards the side of the first overflow valve 72
Stretch.Moreover, when being powered, proportional solenoid 74c thrust is also transmitted to the valve body 72a of the first overflow valve 72 via push rod 74d,
Above-mentioned thrust plays a role towards the direction of resistance spring 72b active force.
Therefore, the first overflow valve 72 is configured to：When the pressure for compressing side room R2 exceedes cracking pressure, direction makes damping
Thrust produced by the direction that passage 7 is opened promotes the pressure in valve body 72a compression side room R2 is produced with proportional solenoid 72c
Raw thrust sum, makes effect of the direction that damp channel 7 is blocked to the spring 72b of valve body 72a application active forces more than direction
Power, so that valve body 72a is retreated and opened damp channel 7.That is, the proportional solenoid of the first overflow valve 72 and switch valve 74
74c together constitutes with variable overflow valve, can adjust valve opening pressure by supplying to the regulation of the proportional solenoid 74c magnitude of current
Power.
And then, in above-mentioned variable damper valve 71, in failure, because switch valve 74 is located at communicating position, therefore, even if
The cracking pressure of first overflow valve 72 becomes maximum, but when compression side room R2 cracking pressure of the pressure more than the second overflow valve 73
When, the second overflow valve 73 can open subaisle 7a.In addition, when being powered, because subaisle 7a is hindered by switch valve 74
Disconnected, therefore, compression side room R2 liquid does not pass through the second overflow valve 73 and moved towards storage tank T.Therefore, because according to it is above-mentioned can
Mutative damp valve 71, second acted when can be by the cracking pressure of the first overflow valve 72 acted when controlling and failure
The cracking pressure of overflow valve 73 is independent of each other and independently set, therefore, it is possible to the damping force made during control and during failure
Respectively reach optimal.

Easily the variable damper valve of the variable grade of overflow valve 70 is arranged on bottom 6.Herein, although damper D2 as shown in Figure 5 that
Variable overflow valve 90 as variable damper valve, can be installed on top cover 5 by sample, still, and top cover 5 is to allow piston rod 4 to insert
Lead to and by cylinder body 1 and the component of the closure of openings of outer shell 2, and when forming runner and installing variable damper valve, structure becomes multiple
It is miscellaneous.In addition, being in most cases provided with one end of dust cover (not shown) on top cover 5, the dust cover is by outside the piston rod 4
Week covering is so as to protect the sliding surface of piston rod 4.Therefore, when variable damper valve is arranged on top cover 5, it is necessary to avoid dust-proof
Cover and variable damper valve is installed, thus it is not easy to install.Further, since variable damper valve is heavier, therefore, pacify by such weight
During neighbouring loaded on the part being supported to piston rod 4, the part is tilted relative to piston rod 4, it is possible to hindering
The smooth movement of piston rod 4.
From above-mentioned situation, when variable damper valve is installed on bottom 6, the first damper DL and can be simplified
Two damper DR structure, so as to reduce cost, further, it is possible to make piston rod 4 good relative to the action of cylinder body 1.Profit
The effect above can be also obtained with damper D1, also, no matter how the structure of variable damper valve can obtain above-mentioned certainly
Effect.
In addition, the composition of the damper of pressure action type is not limited to above-mentioned composition, can also suitably it be changed.Separately
