Embodiment
Below, be described with reference to the embodiment of accompanying drawing to axle spring of the present invention.In addition, as shown in Figure 1, because urceolus 2 is more with the situation being in upper state use relative to main shaft 1, therefore this state is called upright state, and specifies up and down with this upright state.
According to the present invention, as shown in Figure 1, axle spring A comprises: main shaft 1; Urceolus 2; Spring section 3, its intervention is arranged between these main shaft 1 and urceolus 2; And block 4, it is arranged on the upper end portion of main shaft part 1.As shown in Figure 1, the situation that axle spring A is positioned at the upright state use below urceolus 2 with main shaft 1 is more, but is not limited thereto.
Main shaft 1 there is axle center P and viewed from the direction of axle center P time rounded, main shaft 1 comprises: the supporting portion 1A of lower end, and it is subject to the support of chassis side; The main part 1B on top; Lip part 1C, its supporting portion 1A and main part 1B upper and lower between; Hollow portion 1D rounded when overlooking, what it was formed to supporting portion 1A from upper end centre haply.Outer circumferential face 5 and the inner peripheral surface 6 of main part 1B are formed as, and more become more downward large conical surface (tapered outer circumferential surfaces, inverted cone inner peripheral surface) relative to the diameter of axle center P.That is, hollow portion 1D with its diameter on the direction of axle center P from annular end face 1b more towards the deep inside of main shaft 1 more become large mode be formed as bottom enlarged shape.
Cylindric urceolus 2 comprises: skirt (skirt) portion 7, and it has and more becomes more downward large conical surface, i.e. tapered inner circumferential surface 7a relative to the diameter of upper and lower axle center P; And cylinder top 8, it is positioned at the top in skirt section 7.The angle of inclination of circular cone inner peripheral surface 7a and direction setting become identical with the outer circumferential face 5 of main part 1B.Cylinder top 8 is that to have relative to the diameter of axle center P be the part of fixing inner peripheral surface substantially, and described cylinder top 8 is formed with the bigger insertion part 8a of diameter, makes following fixed component 18a etc. can be embedded in insertion part 8a.
This urceolus 2 with time from the side compared with main shaft 1 closer in upside and the state of surrounding main shaft 1 from outside configure, its condition is the underpart of urceolus 2 and the position residing for the upper end portion of main shaft 1 is identical height level.
Spring section 3 is, by by the elasitic layer 11,12,13 of first and second inside and outside middle hard cylinder 9,10 and rubber with the state with axle center P concentric (or roughly concentric also can), alternately laminatedly in radial inward-outward direction to form.
Each the middle hard cylinder 9,10 be made up of metallic material etc. and each elasitic layer 11-13, be formed as on the direction that the outer circumferential face 5 with main part 1B is identical with the circular cone tubular that equal angular tilts.The inner peripheral surface of the first elasitic layer 11 of inner side is formed integrated by methods such as bonding by Vulcanizations with the outer circumferential face 5 of main shaft 1, and the outer circumferential face of outermost 3rd elasitic layer 13 is formed integrated by methods such as bonding by Vulcanizations with the tapered inner circumferential surface 7a of urceolus 2.
As shown in Figure 1, block 4 is components of the stepped cylindrical shape with the larger service portion A of diameter and the less assembly department 4B of diameter, and it is formed by having flexual elastic material such as rubber.The diameter of assembly department 4B is set as that described assembly department 4B can be pressed into the value of the top degree of the hollow portion 1D in main shaft 1, mobile by being forced downwards by assembly department 4B, end difference (ladder surface) 4a making assembly department 4B be inserted into ring-type can be loaded into the position of the annular end face 1b of main part 1B.As method block 4 being fixed to main shaft 1, such as can for the method such as bonding except being pressed into.
As shown in Figure 6, axle spring A is such as used as the unit of axle box 17 suspension strut at chassis frame 18, and wherein, described axle box 17 is for the axletree 16 of the wheel 15 of support iron road chassis 14.In this example, be configured with axle spring A respectively in the front and back of axletree 16, on the upside of the spring identical with rail truck (omit and illustrate), be namely fixed on the embedded insertion part 8a being fixed on urceolus 2 of fixed component 18a of chassis frame 18.Accommodation section 17a rounded when main shaft 1 is by being embedded in viewed from above-below direction by its supporting portion 1A is configured in axle box 17, and wherein, described accommodation section 17a is formed with state recessed downwards at axle box 17.
As the example that block 4 works, rail truck (time more than staffing by bus) heavy load as emergency braking when full can be enumerated and put on the situation of chassis.Following state shown in example shown in Fig. 2: make spring section 3, relative to main shaft 1, resiliently deformable occur, fixed component (example of the body that is fixed) 18a is made to decline significantly thus, thus make fixed component 18a not only be connected to the annular upper face 2a of urceolus 2, but also be connected to the state of the upper surface 4b of block 4.In this condition, if fixed component 18a declines relatively further, then till current only by the state under the elastic reaction of spring section 3, and be formed as now the state of the elastic reaction being also added block 4.
Therefore, if resiliently deformable from spring section 3 to the fixed component 18a amount of deformation be connected on P direction, axle center when block 4 abuts, spring section 3 to be set as α (established amount relative to close to move), then the pass between the amount of deformation of spring section 3 and load ties up to shown in the chart of Fig. 3.Namely, when amount of deformation is at below α, represent resiliently deformable change (mild nonlinear line x) under only being acted on by spring section 3, if amount of deformation is more than α, change the resiliently deformable change (steep anxious nonlinear line y) under being acted on by both spring section 3 and block 4 into.In addition, dotted line z represents change when not having block 4 (only having the situation of spring section 3).
Because block 4 utilizes the structure of main shaft 1 (hollow portion 1D and annular end face 1b) releasably to install, therefore, except installation and removal become easily, parts can also be changed separately.In addition, also existing axle spring can be arranged on by adding after block 4.By changing size (diameter, height etc.) or the hardness (rubber hardness, spring constant) of service portion 4A, adjustment setting can be carried out to nonlinear characteristics.In addition, by changing the size of assembly department 4B, also can finely tune spring performance or the length of durability be set.
As shown in Figure 1, for block 4, when the height dimension of service portion 4A being set as h1, the height dimension of assembly department 4B is set as h2 and by between the upper surface 4b of the block 4 and upper surface 2a of urceolus 2 between the upper and lower in time being set as X, preferred h2 > X.
Because upper surface 2a is provided with fixed component 18a (with reference to Fig. 2), the gap size therefore between the upper and lower when X is so-called empty wagons between block 4 and fixed component 18a.When full, the violent not shown lower body face (or fixed component 18a) to move up and down etc. abuts with the upper surface 4b of block 4 (with reference to Fig. 2), block 4 can be close to lower body face, then, when lower body face rises mobile, block 4 may be extracted from main shaft 1.
Therefore, if be set as h2 > X, then tool has the following advantages: even if be in above-mentioned condition, and block 4 also can not be extracted from main shaft 1 completely, when block 4 by the decline again of vehicle body move press and turn back to origin-location time, can maintain and insert the state of main shaft 1 of being supported in.
In addition, when the fixed component 18a such as lower body face are embedded into the structure of insertion part 8a of urceolus 2, about the interval X that the line of being drawn by double dot dash line in Fig. 1 represents, h2 > X is set as.
In addition, special provision be there is no to the ratio of the height dimension h1 of service portion 4A and the height dimension h2 of assembly department 4B, but from obtaining the viewpoint of stable braking characteristic or sufficient durability, can adopt the structure being set to h1 < h2 yet.
As shown in Fig. 1 etc., the upper end peripheral part of service portion 4A is formed circle or oblique cutting, in addition, if the lower end perimembranous of assembly department 4B to be formed circle or oblique cutting, then there is durability and improve or the advantage improved such as be easy to insert.
