Description
Technical field
The present invention relates to the aseismatic mechanism of a kind of pneumatic spring used in the moving bodys such as railway vehicle and the moving body using pneumatic spring.
Background technique
Pneumatic spring has the ride quality improved when moving body travels, and, do not rely on number of passengers, all the time the step between car body and platform is kept the speciality such as constant, extensively used as the aseismatic mechanism parts between the car body of railway vehicle and bogie.The ride quality this respect of pneumatic spring when improving usually traveling by using the barrier film by air expansion has superiority.On the other hand, there is following shortcoming: when exitting, after air release, barrier film cannot play a role; Substantially horizontal spring constant, close to linear, stops the ability of the substantially horizontal relative movement of bogie and car body weak.Therefore, for ride quality when improving venting or the object of derailing preventing railway vehicle, the structure in the inside of barrier film or outside with stop rubber is adopted.
In patent documentation 1, about the stop rubber be arranged in barrier film, disclose following structure, by the 2nd stop rubber of high spring-constant of the axial deflection of the 1st stop rubber and restriction the 1st stop rubber that arrange low spring constant, thus play nonlinear spring performance, reduce the impact on ride quality, the deflection of restriction vehicle, thus safe traveling can be realized.
In patent documentation 2, as the Retraining Measures of substantially horizontal displacement, disclose following structure, it utilizes the movement of the substantially horizontal of the housing restriction pneumatic spring of stop flange and stop component or diaphragm sides.Above-mentioned structure attempts by making substantially horizontal spring constant become non-linear, thus in order to tackle the speed up in vehicle, and suppress by left and right directions rate of travel during bend point, suppress the significantly yaw of car body, the deterioration of ride quality.
Patent documentation 1: Japanese Unexamined Patent Publication 2006-105244 publication
Patent documentation 2: Japanese Patent No. 3400551 publication
The structure of patent documentation 1 to keep ride quality when exitting, and the deflection of restriction car body, thus the structure of safety traffic, but do not improve the spring constant of substantially horizontal.Patent documentation 2 can limit the displacement in left and right vehicle wheel direction, makes spring constant have nonlinear characteristics, but there is following problem, that is, in the method in outside housing being located at barrier film, pneumatic spring maximizes, in addition, inoperative when exitting.In addition, in the structure using stop flange, there is room for improvement in having an impact in the collision when stop component action to ride quality.In addition, these structures all likely make the structure of pneumatic spring become complicated, cause cost to increase.
Summary of the invention
Therefore, the object of the invention is to obtain one and can utilize and more simply construct, take into account moving body aseismatic mechanism and the pneumatic spring of ride quality and vehicle run stability.
To achieve these goals, the aseismatic mechanism of moving body of the present invention be arranged on moving body vehicle between car body and bogie, and there is the Shockproof of vehicle mechanism of pneumatic spring, wherein, this moving body vehicle has bogie and is positioned in the car body on this bogie, described pneumatic spring has barrier film, and the stop rubber be arranged between this barrier film and described bogie, suppression face component is provided with in the aseismatic mechanism of this moving body, this suppression face component is being separated with the side of described stop rubber, and by the described distortion of stop rubber the position contacted at least partially of the side with described stop rubber, there is the suppression face with this contacts side surfaces.
Utilize above-mentioned structure, when usually travelling in the scope that the Horizontal displacement of pneumatic spring is less, because the side of stop rubber and suppression face are arranged discretely, therefore, stop rubber is in free state in the horizontal direction, can keep less by the substantially horizontal spring constant of aseismatic mechanism (namely soft), and, under the state of necessity, substantially horizontal spring constant can be made to become large (firmly) and work.
Can be configured to, the direct of travel of moving body vehicle is being set to fore-and-aft direction, the direction orthogonal in horizontal plane with fore-and-aft direction is set to left and right directions, by the distortion of the left and right directions of the corresponding stop rubber of the relative displacement of the left and right directions with car body and bogie, thus the side of stop rubber contacts with suppression face.Due to centrifugal force during negotiation of bends, under the state that car body waves in the lateral direction, if stop rubber is out of shape to the left and right, then contacted with suppression face by the side of stop rubber, by being further out of shape, this distortion is suppressed, thus spring constant becomes large (namely hardening), displacement is suppressed gradually.
In addition, can be configured to, when barrier film is exitted, by the distortion of the stop rubber caused by the load that is applied to the above-below direction on stop rubber, and the side of stop rubber be contacted with suppression face.When barrier film is exitted (during so-called explosion), when applying the load of larger above-below direction to stop rubber, stop rubber due to the compression of above-below direction to substantially horizontal dilatancy, but in the case, the side of the stop rubber expanded is suppressed face and suppresses, its result, gently can stop the displacement of above-below direction.
As pneumatic spring as above, as long as have by the barrier film of top plate and lower panel clamping with by the stop rubber of lower panel and grip block clamping, suppress face component to be fixed on grip block, or be configured to a part for grip block.
On the basis of existing air-spring design, suppress face component by installing in a part for grip block, or suppression face component is formed integratedly as the part structure of grip block, thus with low cost, the structure with suppression face can be realized.Especially, if face component also will be suppressed one-body molded when manufacturing grip block, then cost advantage will be obvious.
On the other hand, suppress face component also can be fixed on bogie, or be configured to a part for bogie.As pneumatic spring, can directly use existing structure, cost advantage is obvious.In addition, by forming suppression face in bogie side, thus the design freedom of face component is suppressed to improve.
Preferably be configured to, the area of contact between the side of stop rubber and suppression face, change corresponding to the deformation extent of stop rubber.Its reason is, little by little can increase spring constant, can suppress the change in displacement of violent car body, improve ride quality.
As the example of said structure, the side of preferred stop rubber is circular cone or spindle shape, and upper surface and lower surface are plane shape, and suppression face is substantially vertical wall.Or also can be that the side of stop rubber is substantially vertical shape, upper and lower surface be plane shape, and suppression face is the wall of following shape, that is, form a part of side of circular cone or spindle shape.
In addition, suppression face can be formed with resinous coat.Usually, the component inner surface of pneumatic spring is the face directly produced by stamping die or forge mould, mold, mostly coarse and obviously concavo-convex.In the present invention, owing to playing function by the contact with stop rubber, therefore, when coarse surface, the harmful effect of life of product that the damage due to rubber causes or function aspects is produced.Therefore, preferred pin, to the part contacted with stop rubber suppressing face, reduces surface roughness, is more preferably formed with resinous coat.The resin that this resin can use nylon, polyethylene etc. general, does not limit especially, but in order to realize low coefficient of friction and particularly preferably fluorine-type resin etc.
In said structure, the direct of travel of moving body vehicle can be set to fore-and-aft direction, the direction orthogonal in horizontal plane with fore-and-aft direction is set to left and right directions, suppression face is being arranged in the lateral direction, and does not arrange in the longitudinal direction.Or, following shape can be formed, that is, compared with left and right directions, suppress the separating distance between face and the side of stop rubber larger in the longitudinal direction.On the fore-and-aft direction of the direct of travel as vehicle, mostly require that pneumatic spring is as far as possible soft, therefore, preferably do not suppress the distortion of stop rubber in the longitudinal direction.
In addition, the present invention comprise as moving body aseismatic mechanism as above pneumatic spring monomer and use and have the moving body vehicle of above-mentioned moving body aseismatic mechanism.
The effect of invention
According to the present invention, one can be obtained and can utilize and more simply construct, take into account the moving body pneumatic spring of ride quality and vehicle run stability.

Embodiment
With reference to accompanying drawing, the structure of pneumatic spring involved in the present invention is described.In addition, mark the key element of identical label in different drawings, represent identical or corresponding key element.The present invention is not limited to these contents, but by shown in claims, comprises the content identical with claims and the whole changes in scope.
Fig. 1 is the generalized section of the pneumatic spring represented as an example of the present invention.Fig. 1 represents along by the vertical surface of the central shaft of pneumatic spring, by the section that this pneumatic spring is cut open, plan view, worm's eye view is not shown, but entirety be rotate centered by central shaft and obtain round-shaped.Fig. 1 is used to be described basic structure key element of the present invention and its effect.The essential structure of pneumatic spring is made up of barrier film 4, and upper and lower surface is sealed and clamping by top plate 1 and lower panel 2 by this barrier film 4 respectively.The structure of top plate 1 and lower panel 2 is not simple plate, and there is the structure of various complexity, but which kind of structure what do not focus on that it adopts in the present invention is, therefore in each accompanying drawing headed by Fig. 1, as an one example, representative structure is schematically shown.Barrier film 4 is filled air by compression in the space clamped by top plate 1 and lower panel 2 and expands.Top plate 1 is arranged on the car body side of vehicle, the weight on barrier film 4 supported cart side, makes air play the effect of spring.
The pneumatic spring of Fig. 1 below between plate 2 and grip block 6, the position of the outside of barrier film 4 has stop rubber 5.Because stop rubber is located at exterior, therefore, also referred to as outside stop component.In FIG, stop rubber 5 abuts with lower panel 2 with its upper surface, the block rubber that the mode that its bottom surface abuts with grip block 6 is arranged.Grip block 6 is fixed on bogie side.In this condition, stop rubber 5 as the spring of connecting with barrier film 4 supported cart body weight.
Fig. 2 is the figure of the state (this state is called deflation status) after the air release of the pneumatic spring representing Fig. 1.If become deflation status, then barrier film 4 cannot play the function as pneumatic spring.Top plate 1 declines downwards owing to being subject to from the load on its top and the load of car body side, contacts with lower panel 2.At this, due to the existence of stop rubber 5, therefore only stop rubber 5 load-supporting.Stop rubber 5 is owing to being subject to the load from top, and to be crushed in the vertical direction, the mode expanded in the lateral direction is out of shape.
In addition, the size of the pneumatic spring shown in Fig. 1 is, such as, the outer diameter of top plate is 350 to 1000mm, and the diameter of the lower surface of stop rubber is 100 to 500mm, and the diameter of upper surface is 50 to 450mm, be highly 15 to 250mm, the spring constant of stop rubber 5 is about 3 to 15kN/mm, but these etc. correspond to be suitable for railway vehicle specification determine, be not limited to illustrative numerical value.
Suppression face component involved in the present invention and its function are described.In Fig. 1 and Fig. 2, arrange in the mode relative with the side of stop rubber 5 and suppress face component 3.The face relative with the side of stop rubber of face component 3 is suppressed to be worked as suppressing face 3a.At this, so-called side, refer to be connected to stop rubber the upper surface relative with top plate side and the lower surface relative with lower panel side on, and due to the face of the load and this side of dilatancy that are subject to above-below direction.In addition, suppress face component 3 to be configured to discretely, suppress the side of face 3a and stop rubber 5 to become separated state (Fig. 1) when the normal use of barrier film.Once barrier film 4 becomes deflation status, then the side of stop rubber 5 is out of shape by a larger margin due to the increase of load, contacts with suppression face 3a, suppresses its distortion (Fig. 2) by suppressing face component 3.By this suppression, stop rubber 5 is difficult to distortion, that is, become as state harder rubber.
The plotted curve of Fig. 9 illustrates above-mentioned situation.The transverse axis of Fig. 9 represents that the compression displacement amount X of the above-below direction of stop rubber 5, the longitudinal axis represent the compressive load P applied on this stop rubber 5.Barrier film is become deflation status, and top plate 1 contacts with lower panel 2, and the positional representation starting to be applied with to stop rubber 5 lower load is initial point X=0.By the normal load (i.e. the weight of car body side) from top plate 1, stop rubber 5 is constantly compressed, and, be out of shape in the mode of side to lateral expansion.Therefore, relative to load P, compression displacement amount X changes as shown by lineb.But, if the side of stop rubber 5 becomes and the state (P=P suppressing the suppression face 3a of face component 3 to contact
c, X=X
c), then because the distortion of side is suppressed the suppression in face, therefore, the spring constant of rubber becomes large, not as the elongation line (dotted line) of line B, and as shown by line a, reduces relative to the displacement amount of compressive load.It has following effect, that is, at the initial stage when exitting generation, soft rubber car body, on the other hand, carries out suppressing and making car body be difficult to the displacement be more than or equal to a certain degree.If car body is to bogie side exceedingly displacement (sinking), then except the harmful effect such as there is the breakage that is arranged on other equipment base parts between car body and bogie or action is bad, also can produce the problem such as function that cannot play completely as spring.According to the present invention, can the problems referred to above be suppressed, and guarantee ride quality when exitting.
As mentioned above, show the example suppressing face component 3 to form integratedly as a part for grip block 6 in the drawings, but also can welding or bolt etc. be utilized to be fixed on grip block 6 the suppression face component 3 as miscellaneous part, in addition, also can be one-body molded.From the viewpoint of manufacture cost or intensity, most preferred integrated situation.In addition, except suppression face component 3 is arranged on except on grip block 6, it also can be the structure be located on lower panel 2 downward.No matter be which kind of situation, as long as be configured to the side of stop rubber and suppression face under the deflation status of barrier film, be configured in relative position, can by with the structure abutting the distortion suppressing stop rubber suppressing face.
From preventing damaged this respect from considering, the contact segment contacted with stop rubber 5 of preferred suppression face 3a is covered by the sliding material of low friction.That is, the friction factor of the tangent direction under the state contacted with stop rubber is preferably utilized to cover than the material suppressing the surface of face component itself little.The sheet material of low friction can be had on surface, but in order to convenient, on suppression face, form coating by the resin outside rubber.Resin material can be polyethylene, PVC＝polyvinyl chloride or nylon etc., does not limit especially, but considers from low friction this respect, the fluorine-type resins such as preferably polytetrafluoroethylene.
Next, with reference to Fig. 3 to Fig. 5, when using the direct of travel of vehicle as fore-and-aft direction, the function of the pneumatic spring of the present invention when there is relative displacement in the lateral direction to bogie and car body is described.Fig. 3 to Fig. 5 is under the state that pneumatic spring is mounted on a vehicle, utilizes the section vertical with the direct of travel of vehicle with the generalized section cut open by the mode of central shaft.
The state neutral in the lateral direction by vehicle, that is, the steady state when common straight-line travelling is as the state of Fig. 3.Be the load upwards applying car body side between panel 1 and grip block 6, supported the state of this load by barrier film 4 and stop rubber 5.Stop rubber 5 does not contact with suppression face 3a.Shown in Figure 4 due to the centrifugal force etc. during negotiation of bends, car body is relative to the state of bogie displacement to the left and right.Panel 1 is relative to lower panel 2 and grip block 6 displacement to the right in fig. 4, the upper.Barrier film 4 and stop rubber 5 are shared this displacement and stop, and barrier film 4 is out of shape and stop rubber 5 is also out of shape.By this distortion, the side (right flank in Fig. 4) of stop rubber 5 is freely out of shape when being out of shape initial, but from the distortion be more than or equal to a certain degree, contacts (Fig. 4) with suppressing the suppression face 3a of face component 3.If continue distortion, then as shown in Figure 5, under the state that a part for stop rubber 5 stops distortion owing to suppressing face component 3, the state of portion deforms freely is only become.If be out of shape suppressed face component 3 to suppress, then the spring constant of stop rubber 5 entirety increases, and namely becomes harder rubber.
Also illustrate in Figure 5 and suppress face component 3 to contact with lower panel 2 in left side, do not continue the ultimate state of displacement to the right.As mentioned above, by making the displacement of the left and right directions of stop component stop under certain conditions, thus contribute to stable traveling, and suppress the durability of stop component itself to decline.As existing known configuration, there is the stop component flange etc. of the movement mechanically stoping lower panel, but these structures are prevented compared with the displacement of lower panel 2 with Fig. 5 by abutting with suppression face component 3, have identical function in the displacement stoping substantially horizontal.According to suppression surface construction of the present invention, as reaching the last stage before mechanically stoping, because the spring constant of stop rubber increases gradually, therefore, it is possible to relax the impact of this prevention to passenger, can contribute to further improving ride quality and stable traveling.
Figure 10 is the plotted curve of the characteristic that the pneumatic spring shown in from Fig. 3 to Fig. 5 is described.The transverse axis of Figure 10 is top plate 1 and grip block 6, that is, the relative shift X of the substantially horizontal of car body and bogie, and the longitudinal axis is the load P of the substantially horizontal to stop rubber 5 applying.Be initial point X=0 by the state representation of Fig. 3 neutral in the horizontal direction for vehicle.Start the stage increased at X, the spring constant of substantially horizontal is determined by the synthesis of barrier film 4 and stop rubber 5.Displacement continues to become large, and the side of stop rubber 5 is X with the displacement of the state suppressing face 3a to contact
c.By suppressing face to suppress displacement, thus the spring constant of stop rubber 5 increases, and slope of a curve becomes large.Owing to becoming large gradually with the impact suppressing face 3a to contact, therefore, spring constant increases gradually, in the graph, depicts the curve protruded as downwards.Then, lower panel 2 plays the position of interception is X
s.Following stop rubber 5 is inoperative, only changes according to the spring constant of barrier film 4.As mentioned above, by producing interim load variations, thus suppressing the change of impact, can contribute to realizing good ride quality.On the other hand, as compared with not suppressing the situation of face component 3, line B is shown.This line B is at displacement X
cand X
splace does not change, and dull change is shown.At this, when also having the stop component structure of other mechanisms, utilize the effect of stop component can produce the change of spring constant sharply.
Fig. 6 to Fig. 8 is as another configuration example of the present invention, stop rubber is replaced to the example of the stacked stop rubber 50 be made up of laminated latex.Stacked stop rubber 50 is by structure multilayer laminated for plywood 50a and laminated latex 50b, and wherein, the sheet metal of the disc-shape of this plywood 50a Shi center apertured, this laminated latex 50b has the disc-shape with plywood 50a same thickness.Above-mentioned stacked stop rubber is widely used in the field of pneumatic spring, and detailed configuration uses known technology.
The state that vehicle is neutral in the lateral direction, that is, the steady state when common straight-line travelling is the state of Fig. 6.The load upwards applying car body side between panel 1 and grip block 6, the state that this load is shared by barrier film 4 and stop rubber 5 and supported.Stacked stop rubber 50 does not contact with suppression face 3a.Shown in Figure 7 due to the centrifugal force etc. during negotiation of bends, car body is relative to the state of bogie displacement to the left and right.In the figure 7, top plate 1 is relative to lower panel 2 and grip block 6 displacement to the right.Barrier film 4 and stacked stop rubber 50 are shared this displacement and stop, and barrier film 4 is out of shape and stacked stop rubber 50 is also out of shape.By this distortion, the side (right flank in Fig. 7) of stacked stop rubber 50 is freely out of shape when being out of shape initial, but from the distortion be more than or equal to a certain degree, contacts (Fig. 7) with suppressing the suppression face 3a of face component 3.If distortion continues further, then as shown in Figure 8, under the state that a part for stacked stop rubber 50 stops distortion because suppressing face component 3, the state of portion deforms freely is only become.Suppress face component 3 to suppress distortion if utilized, then the spring constant of stacked stop rubber 50 entirety increases, and namely becomes harder rubber.In fig. 8, identical with the situation of Fig. 5, illustrate and suppress face component 3 to contact with lower panel 2 in left side, do not continue the ultimate state of displacement to the right.
When using stacked stop rubber, stacked each laminated latex 50b works as the elastomer of series connection.Therefore, in order to little by little play the inhibition suppressing face component 3 to be brought, can arrange tilt a little by suppressing the suppression face of face component 3, or be set to, corresponding to each laminated latex with step-like expansion.
Figure 11 is the figure that another configuration example of the present invention is described.Be with the difference of the pneumatic spring shown in Fig. 1, pneumatic spring self does not suppress face component.The feature of the aseismatic mechanism of the moving body of Figure 11 is, makes the suppression face component be arranged on bogie and the pneumatic spring concerted action with outside stop component, plays the effect of aseismatic mechanism.
Figure 11 is along the vertical surface by the central shaft of pneumatic spring, by the section that this pneumatic spring is cut open, schematically represent the section vertical with vehicle direct of travel, plan view, worm's eye view be not shown, but pneumatic spring be centered by central shaft rotation and obtain round-shaped.Pneumatic spring has barrier film 4 and stop rubber 5, and wherein, this barrier film 4 utilizes top plate 1 and lower panel 2 upper and lower surface to be sealed and clamping respectively, and this stop rubber 5 is arranged between lower panel 2 and grip block 6, and is in the position of the outside of barrier film 4.Shown in Figure 11, stop rubber 5 abuts with lower panel 2 with its upper surface, and the mode that its bottom surface abuts with grip block 6 is arranged, and side is the situation of the block rubber of a part of side view of roughly spindle.Grip block 6 is arranged in bogie upper side 20.The upper side 20 of bogie is fixed with and suppresses face component 30, this suppression face component 30, around the stop rubber 5 of pneumatic spring, has and the side of stop rubber 5 suppression face 30a in a distance.Suppress face component 30 also can be fixed on as miscellaneous part on bogie, also can be formed as one-body molded with bogie.
Figure 12 is the stravismus schematic diagram of the suppression face component 30 illustrated in the structure of Figure 11.Face component 30 is suppressed to be arranged in bogie upper side 20 to suppress the face 30a mode relative with the side of stop rubber.The shape or the mounting construction that suppress the part except suppressing face 30a of face component 30 are arbitrary, as long as can install have enough intensity and work.Figure 12 illustrates a pair suppression face 30a is generally perpendicularly fixed on bogie upper side example in mode respect to one another.
In the structure of Figure 11, suppress the function of face component self to have with pneumatic spring as above and suppress the situation of face component identical.As shown in figure 11 and the advantage formed is, pneumatic spring self, without the need to arranging special structure, can realize overall cost reduction, design freedom raising etc.
The configuration example of face component is suppressed shown in Figure 13 (a) to (e).Figure 13 is only retrieval inhibition face component, and the figure of the arbitrary section of top view is the schematic diagram of the configuration representing suppression face.Mark fore-and-aft direction and the left and right directions of the vehicle carried to some extent.The spring constant of pneumatic spring is preferably soft on vehicle direct of travel, suppresses the function in face mainly to require the displacement of left and right directions when suppressing negotiation of bends.Therefore, be preferably configured to, suppress face to arrange in the lateral direction, and do not arrange in the longitudinal direction.Above-mentioned example shown in the (a) and (b) of Figure 13, (c).In addition, also can be formed as following shape, that is, suppress face component continuous in the longitudinal direction, with the separating distance of the side of stop rubber, compared with left and right directions, larger in the longitudinal direction.(d), (e) of Figure 13 illustrates above-mentioned configuration example.Especially, suppression face component be located in the structure of bogie side, the design freedom with the shape of above-mentioned suppression face component is high, is easy to the advantage of the effect obtaining expectation.
In such a configuration, what enumerate is shape as stop rubber 5, in Fig. 1, Figure 11, side is a part of shape of spindle, upper surface and lower surface are plane shape, suppression face 3a, 30a of suppression face component 3,30 are the example of substantially vertical wall, but in addition also can be following structures.
First, as basic mode, side and both suppression faces of stop rubber can be vertical faces.In the case, stop rubber becomes substantial cylindrical shape.Due to the load of above-below direction, the side of stop rubber is such as thick with the central part of above-below direction, and the thin mode of upper and lower end parts is out of shape unevenly, therefore, for upper and lower load, abuts successively from the part expanding thicker with suppression face.For the displacement that left and right load causes, work in the mode first contacted with suppression face away from this side of grip block.The difference of above-mentioned shape shows as, different with curve shape from the slope of the line A in the plotted curve of Fig. 9.Therefore, it is possible to carry out various design, to make, by the side of stop rubber and the configuration shape (interval and slope) suppressing face, to become the spring constant of expectation.In order to realize the change of milder spring constant, be preferably configured to, the separation spacing in side and suppression face increases in the vertical direction or reduces.The side of stop rubber can be spindle shape as shown in Figure 1 or cone shape, the suppression face 3a suppressing face component 3 can be substantially vertical wall, in addition, the side of stop rubber can be substantially vertical shape, suppression face can be the wall of following shape, that is, forming a part of side of circular cone or spindle shape, also can be above-mentioned combination.
