である。2. Description of the Related Art Conventionally, air springs used as suspension springs in railway vehicles, automobiles, etc. have lost their function as air springs due to breakage of a bellows or diaphragm constituting the air spring or failure of an air system. for,
Further, a stopper made of a rubber-like elastic body or the like is provided inside or outside in order to buffer the impact against the excessive displacement and to limit the displacement. Therefore, since the spring characteristic of the stopper is a temporary load supporting device when the air spring fails, and is a device that limits excessive displacement, the vehicle or the like is supported only by this stopper in the conventional method. Therefore, it is difficult to carry out normal traveling in order to absorb the vibration.

て、要求される性能の空気ばねを提供する点にある。However, in recent years, in air springs used in railway vehicles, there is a demand to add a function of a suspension spring other than the purpose of the stopper of the conventional air spring. This is because it takes time to fill the air spring with air when the vehicle suspended by the air spring is being transported or moved on the premises, so that the vehicle is run without being filled with air. Moreover, it is used at normal operating speed. For this reason, the spring constant that supports the vehicle is too high with the conventional air spring stopper without filling the air spring with air, and the function of absorbing vibration during running cannot be obtained, and the vehicle cannot be safely driven. It is said. Therefore, the stopper installed in the air spring also needs to support the load of the vehicle when the vehicle is empty, and has a spring characteristic that is substantially the same as the spring constant of the air spring. As a means to solve this problem,
A proposal to provide another rubber spring outside the air spring is also conceivable, but this is not preferable because it causes a drastic change in the bogie structure in the mounting space, reinforcement of the support base, and the like, which causes a cost increase. An object of the present invention is to provide a pneumatic spring having required performance by reducing the cost as much as possible and suppressing the cost increase by improving and devising a stopper installed in the air spring like the conventional air spring.

る。The present invention has been achieved as a result of intensive research to solve the above problems, that is, the present invention relates to an air spring having a central ventilation part communicating with an auxiliary air chamber. A doughnut-shaped rigid plate which is continuous in the diameter direction between the annular rubber elastic bodies of 2 to 4 layers and the independent annular rubber elastic bodies around the ventilation part, and between the annular rubber elastic bodies of 2 to 4 layers , Two or more are provided for each annular rubber elastic body or including a portion continuous in the diameter direction,
It is equipped with stacked stoppers, and the stopper of the outermost ring part of 2 to 4 layers in which such an annular rubber elastic body and a doughnut-shaped rigid plate are laminated is pre-compressed with a pre-compression retainer, and each of the other annular stoppers is also compressed. The annular stopper is configured to have different spring constants, and the height of the air spring of the annular stopper in the direction of the central axis of the air spring is such that the outer annular portion becomes higher in order from the inner annular portion. It is composed of elastic material and rigid donut-shaped plate. Further, the spring constants of the respective annular stoppers may be the same. Even if the air spring with this stopper is used without being filled with air, it supports the vehicle in an empty state, and even when traveling at normal speed, vibration damping due to traveling is possible and the vehicle can travel safely. I can.

Therefore, according to the present invention, when the inside of the upper plate of the air spring is in contact with the stopper, the stopper of the vehicle is almost the same. Since the pre-compression press has been compressed in advance to obtain a reaction force equivalent to the empty vehicle load, even if the vehicle load of the empty vehicle is applied to this stopper, the deflection due to this static load does not increase. The non-linear load deflection characteristics in which the spring constant can be adjusted, the vehicle runs in this state, the dynamic load due to vibration is added and the deflection also increases, and the spring constant increases in sequence by contacting the inner annular stopper. The performance of is obtained.

FIG. 1 is a cross-sectional view of an air spring according to the present invention. The annular stopper is double-layered, and the stopper at the outermost annular portion is pre-compressed so that it can support the load when the vehicle is almost empty at the same time as it comes into contact with the stopper. The pad 6 and the precompression pad 7 are restricted so that a constant stopper distance can be maintained at the neutral height of the air spring. The outermost annular portion and the next annular portion of the doughnut-shaped rigid plate (intermediate plate) are partially composed of a structure that is continuous in the diameter direction,
The spring constants of the annular stoppers are Ka, Kb,

The spring constant of Kc acts. 2, 3 and 4 show another embodiment of the spring constant selection of the present invention.
In the cross-sectional view of the quadruple annular stopper portion, the portion that comes into contact with the stopper pad is divided into four folds, but the donut-shaped rigid plate (intermediate plate) is arranged in two, three, and four folds from the middle. is there.

ことができる。FIG. 5 is a graph showing a load / deflection curve for explaining the present invention. That is, in the case of the conventional air spring stopper with a built-in stopper, a considerably high spring constant (K) is required to support the empty load (P) of the vehicle within a fixed deflection range.
O ) has to be taken into account, and it is therefore difficult to dampen the vibration due to running of the vehicle with such a high spring constant. According to the present invention, the spring constant is lowered to reduce the traveling vibration of the vehicle so that the vehicle can travel normally.
The pre-compression (P O ) is applied at the position of, and the static deflection when the empty static load (P) of the vehicle is applied to the stopper can be made almost the same as the conventional one having a high spring constant. Next, when the dynamic deflection increases due to the traveling of the vehicle, the annular stopper sequentially obtains a nonlinear spring-deflection diagram in which the deflection spring constant is Ka + Kb Ka + Kb + Kc Ka + Kb + Kc + Kd. A spring constant is high, and it is possible to provide a stopper for an air spring having a characteristic of having a stopper effect.

である。EFFECTS OF THE INVENTION When the bellows or diaphragm constituting the air spring is damaged or the function of the air spring is lost due to a failure of the air spring system, or when the air spring is not filled with air when the vehicle is forwarded or the like. When traveling, it has a performance close to the spring characteristics of an air spring, lowers the spring constant when the displacement is small, and increases the spring constant when the displacement is large.
This is an air spring that has a great effect in ensuring the safety of the running of the vehicle when the vehicle is empty, from the viewpoint of vibration damping, by the non-linear load / deflection characteristics that combine the spring constants of the annular stoppers.
