Description
Technical field
The present invention relates to rubber air spring technical fields, more particularly to the self- recoverage of, damping anti-sway for vehicle etc.
Rubber air spring.
Background technology
Now with the development of vehicle, it is cross-country that rubber air spring is widely used in load-carrying vehicle, offroad vehicle and SUV
In vehicle, bus, high ferro etc., for airsuspension system, air damping system, utilization rate on heavy goods vehicles is more than 80%,
It 100% is used on bullet train and luxurious city bus, there are also installed this systems for part car.Air rubber spring is outstanding
Ground clearance sensor can be all equipped near the vehicle front wheels and rear wheels of frame, by the output signal of ground clearance sensor, row
Vehicle computer can judge that bodywork height changes, then control air compressor and drain tap, and spring is made to compress or extend automatically, from
And chassis road clearance is reduced or increases, to increase the passability of high speed vehicle body stability or complex road condition.
Certainly, traditional suspension is compared, since the adjustable suspension frame structure of air type is complex, the probability and frequency that break down
Rate can also be higher than screw spring suspension system, and use air as the power resources of adjustment chassis height, the sealing of associated components
Property be also a problem, in addition, if continually adjusting chassis height, it is also possible to cause air pump system hot-spot, can be big
The big service life for shortening air pump.
Invention content
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides self- recoverage rubber air spring, its object is to
It by improving the design feature of its own, realizes and improves the automatic recovery ability of rubber air spring at work, enhancing rubber is empty
The intensity and self-adjusting ability of gas spring, extend its service life, and improve its quality.
The technical solution adopted in the present invention is：Self- recoverage rubber air spring, including cylindrical bodies, cylindrical bodies are extremely
Few one end is equipped with bent capsule portion, and bent capsule portion includes at least two and its bent capsule unit above；The both ends of each bent capsule portion inner wall
It is left and right raised equipped with extending to cylindrical bodies axial centre position, and the left protrusion inside each bent capsule portion and the right side
Spring is provided between protrusion.The self- recoverage rubber air spring of the present invention is equipped at least one end of its cylindrical bodies by not
The bent capsule portion that bent capsule unit less than two is constituted, and it is respectively equipped with left protrusion and the right side on the inner wall of the left and right ends in bent capsule portion
Spring is wrapped on the inner wall in bent capsule portion for being clamped spring, enhances the intensity of the rubber air spring first by protrusion；
Secondly, and the structure the most main is by the way of multibody system combination, ensures the self- recoverage rubber air spring just
Often when work, spring is in free state, when being collided or squeezing outside the cylindrical bodies of rubber air spring, inside
Air is compressed, while compressed spring, collision or spring affranchises rapidly state after squeezing, while driving rubber empty
The cylindrical bodies of gas spring are restored to state when working normally, and automatic recovery state are realized, without using external air pump
Supercharging could restore, and on the one hand reduce the workload and working range of air pump, provided for rubber air spring to extend
The service life of the air pump of origin, reduce due to air pump uses for a long time and caused by hot-spot phenomenon, and reduce rubber
The repair of glue air spring.
Further, the corresponding left protrusion of spring and right protrusion bonding, so as to fixed spring.
Further, the corresponding left protrusion of the spring, right protrusion and the bent capsule portion interference connection close to it, will
Each spring clamping makes spring keep mild compression state, is ready to work, facilitates bullet between left protrusion and right protrusion
The dismounting of spring.
Further, the rising height of left and right protrusion is not more than the diameter of spring connected to it.
Further, the length in each bent capsule portion is not more than 1/5th of cylindrical bodies, can preferably delay
The operating pressure for solving air pump, effectively extends its working life.
Further, the bent capsule unit number in each bent capsule portion is consistent with the number of turns of spring, is convenient for compressed spring, and
Material can be saved as best one can.
Further, the pitch for being less than spring along the axial height of cylindrical bodies of each bent capsule unit, it is convenient
Dismounting, installation and the later maintenance of spring.
Compared with prior art, the beneficial effects of the invention are as follows：The self- recoverage rubber air spring of the present invention, in its cylindricality
At least one end of main body is equipped with the bent capsule portion being made of the bent capsule unit for being no less than two, and in the left and right ends in bent capsule portion
It is respectively equipped with left protrusion and right protrusion on wall, for being clamped spring, spring is wrapped on the inner wall in bent capsule portion, is enhanced first
The intensity of the rubber air spring；Secondly, and the structure the most main is by the way of multibody system combination, and ensureing should be certainly
Restore rubber air spring normal work when, spring is in free state, when outside the cylindrical bodies of rubber air spring by
When collision or extruding, inner air is compressed, while compressed spring, and spring restores rapidly certainly after collision or extruding
By state, while the cylindrical bodies of rubber air spring being driven to restore to state when working normally, realizes automatic recovery state,
Without using external air pump supercharging that could restore, on the one hand reduce the workload and working range of air pump, to extend
The service life that the air pump of origin is provided for rubber air spring, reduce due to air pump uses for a long time and caused by part
Superheating phenomenon, and reduce the repair of rubber air spring.
The present invention improves the self- recoverage of rubber air spring at work by improving the design feature of its own, realization
Ability enhances the intensity and self-adjusting ability of rubber air spring, extends its service life, and improves its quality.
Description of the drawings
Fig. 1 is the structural schematic diagram of self- recoverage rubber air spring.
