Abstract

The invention discloses a rubber air spring and application thereof. The rubber air spring comprises a rubber air spring main body, the rubber air spring main body comprises at least one lantern-shaped structure body, the rubber air spring main body comprises an outer rubber layer, a first cord fabric layer and a second cord fabric layer from outside to inside. The rubber air spring is reasonable in design and compact in structure, can serve as an air travel adjuster for use, has the advantages that the original height is small, the bending angle is large, maintenance and lubricating are not needed, no internal operating rod or piston is needed, installation is simple, the allowable working pressure is high, and the cost is low. In addition, the rubber air spring can also serve as an air damping isolator, and has the advantages that the isolation damping capability is good, control over the height is accurate, the vibration isolation efficiency is stable, the damping specialty can be loaded independently, resonance can be prevented effectively, the horizontal stability is good, and noises can be lowered effectively. The rubber air spring has good using effects and high marketing promotion value.

Description

technical field [0001] The invention relates to a buffer device, in particular to a rubber air spring and its application. Background technique [0002] Rubber air springs are commonly known as pneumatic tires, corrugated pneumatic tires, air bags, etc. It is a precision-designed rubber fiber bellows, which does not provide force or support load itself, but fills it with compressed air through an air compressor to achieve force transmission and elastic action. According to the travel requirements, air springs are generally designed with 1-3 curves, and can be designed and manufactured with 4 or more curves when necessary. Under certain conditions, two air springs can also be used superimposed. The air spring has nonlinear characteristics, and its stiffness changes with the load, so its natural frequency remains almost constant under any load, so that the spring device has almost constant characteristics; it has good performance in absorbing high motion and sound insulation;...
