So, under the effect of the load of above-below direction, if urceolus 2 is at the axle center P of main shaft 1
Direction on interval L1 (specified rate) relatively close to, the then middle hard cylinder of initial inner side
The lower end of 5A abuts with inner peripheral portion 11, thus becomes the middle hard cylinder 5A of its above inner side
Restriction state can not be moved to the 1st of main shaft 1 side shifting the.
If increasing load, then it is close, the most now with interval L2 from free state to move urceolus 2
The middle hard cylinder 5B in outside abuts with peripheral part 12, thus becomes in its above outside
Between hard cylinder 5B can not move restriction state to the 2nd of main shaft 1 side shifting the.
Fig. 4 be the main shaft 1 illustrating axle spring A on transverse axis with urceolus 2 on P direction, axle center
Relative displacement, and the load verses displacement figure of load is shown on the longitudinal axis.At urceolus 2 relative to master
Axle 1 is with interval L1 close to before, and elastic 3 is with rubber layer 4A, 4B, 4C of inside and outside three layers
The minimum spring constant k1 of elastic reaction is all occurred to carry out elastic deformation.
Because making the middle hard cylinder 5A of inner side can not carry out close to mobile by interval L1, because of
This urceolus 2 relative to main shaft 1 from interval L1 to interval L2 carry out close to time, elastic layer 3
Elastic deformation is carried out with the spring constant k2 that intermediate rubber layer 4B and outer rubber layer 4C produces.
It addition, because made in addition to middle the hard cylinder 5A of inner side also by interval L2
Outside middle hard cylinder 5B can not close to movement, so urceolus 2 relative to main shaft 1 with
Exceeding under the state that moves of amount of interval L2, elastic 3 is only produced with outside rubber layer 4C
Raw spring constant k3 carries out elastic deformation.
Three spring constants k1, k2, k3 are because having the relation of k1 ＜ k2 ＜ k3, so equipment
The axle spring A of state can as the increase along with main shaft 1 and the relative shift of urceolus 2 bullet
Spring constant becomes the draft hitch of big nonlinear characteristic and plays a role.
For in stop mechanism S as the supporter a of strength member, because at flange
1b is provided with the flange part 6B from upper cover, so the axle center P side acted on locking plate 7
Gear is connect by flange part 6B by flange 1b to the load of (downwards).Therefore, with there is no flange
Supporter a is supported on method by the friction only produced with the fastening force of bolt, nut 13 of portion 6B
Structure on blue 1b is compared, and has and there is not supporter a and come off in P direction, axle center the wind of movement
Danger, and the advantage that can really support load.
It addition, under the non-equipment state being not provided with stop mechanism S shown in Fig. 3, axle spring
The linear suspension characteristic that load is the most proportional to displacement can be obtained.Further, since elastic 3
For section splayed, therefore can allow axle spring A have shown in Fig. 4 along with the increase of displacement
Spring constant is with the big nonlinear characteristic of minimum quantitative change.
As it has been described above, the axle spring A of the present invention may be configured as can at attaching stop mechanism S
The equipment state used as the draft hitch of nonlinear characteristic is non-with not attaching stop mechanism S's
Equipment state selects.
Accordingly, the suspension property of the comfortable feeling for taking that meets the requirements is had the advantage that
Non-equipment state or there is the equipment shape of the suspension property possessing stiffness bearing heavy load
The suspension property of state etc. and output, and except can in addition to the stop mechanism S that attaching connects afterwards other
Can be constant, thus suppression or the open parts carried out because of the demand of catering to caused by special designs
Quantity increases and the complication of artefact management.
If the abutting with middle hard cylinder 5 is highly carried out various change, then can also be to dress
The nonlinear suspension performance (suspension property) of the axle spring A having stop mechanism S is carried out respectively
Plant change setting.Therefore, by the change setting of stop mechanism S, axle spring A self is not only
Can be set to a kind but also the spring with various nonlinear characteristic can be set to.And,
After can carrying out on axle spring A, attaching connects, and therefore having can be to being mounted on physical device
Axle spring carries out attaching, easily realizes nonlinear advantage.
