Further, the left and right projection that each spring is corresponding with it, bonding, so that fixing spring.
Further, also can by left and right projection corresponding with it for each spring, interference connects, and by each spring clamping between left projection and right projection, make spring keep mild compression state, preparatory work at any time, facilitates the dismounting of spring.
Further, left and right projection, rising height be not more than the diameter of connected spring.
Further, the length in each bent capsule portion is not more than 1/5th of cylindrical bodies, just can alleviate the working pressure of air pump preferably, effectively extend its operating life.
Further, the bent capsule number in each bent capsule portion is consistent with the number of turns of spring, is convenient to Compress Spring, and can saves material as best one can.
Further, the height of the axis along cylindrical bodies of every bent capsule unit is less than the pitch of spring, facilitates the dismounting of spring, installation and later maintenance.
Compared with prior art, the invention has the beneficial effects as follows: self-recoverage rubber air spring of the present invention, the bent capsule portion be made up of the bent capsule unit being no less than two is provided with at least one end of its cylindrical bodies, and left projection and right projection is respectively equipped with on the inwall at the two ends, left and right in bent capsule portion, be used for clamping spring, spring is wrapped on the inwall in bent capsule portion, first enhances the intensity of this rubber air spring, secondly, also be the mode that this main structure adopts multibody system to combine, ensure that this self-recoverage rubber air spring is when normally working, spring is in free state, when being collided outside the cylindrical bodies of rubber air spring or extruding, its inner air is compressed, Compress Spring simultaneously, collision or extruding terminate rear spring and to affranchise rapidly state, state when simultaneously driving the cylindrical bodies of rubber air spring to return to normal work, realize automatically returning to form, and without the need to using outside air pump supercharging to recover, decrease workload and the operating range of air pump on the one hand, thus extend the working life of the air pump that origin is provided for rubber air spring, decrease the local superheating phenomenon caused because air pump uses for a long time, and decrease the maintenance of rubber air spring.
The present invention, by improving the structural feature of himself, realizes improve rubber air spring automatic recovery ability operationally, enhances intensity and the self-adjusting ability of rubber air spring, extend its working life, and improve its quality.
