Rigidity-adjustable engineering truck rubber damping equipment

Abstract

The invention relates to the technical field of rubber damping equipment, and discloses rigidity-adjustable engineering truck rubber damping equipment. The equipment comprises a tire, wherein a rotating shaft is movably connected into the tire, the surface of the rotating shaft is sleeved with a hollow channel, a suction pipeline is fixedly connected into the hollow channel, a suction bag is fixedly connected into the suction pipeline, an air supply pipeline is fixedly connected to the position, located on the surface of the suction pipeline, inside the hollow channel, and a rubber sleeve is fixedly connected to the surface of the hollow channel. When a temperature of the surface of the rubber sleeve rises, and the suction bag is pushed by pressure, air in the rubber sleeve can be drained out, and the air and air generated by the air bag are sent out through the air supply pipeline and blown to the surface of the rubber sleeve, so that the effect of reducing expansion deformation of the rubber sleeve when the external temperature is too high is achieved, the rubber sleeve expands and deforms, so that the hardness of the rubber sleeve is reduced, the rigidity is weakened, and the expected working effect is also changed.

Description

technical field [0001] The invention relates to the technical field of rubber damping equipment, in particular to a rubber damping equipment for engineering vehicles with adjustable stiffness. Background technique [0002] Rubber shock absorbers, as an important type of shock-absorbing components, have been widely used in various types of machinery, automobiles, railway locomotives, water vehicles, aircraft and other aircraft; especially for engineering vehicles used to transport ultra-high and overweight equipment. The special nature of work uses rubber shock absorbers more frequently. [0003] The reason why the rubber shock absorber is widely used is that it has durable high elasticity, and has excellent functions of vibration isolation, impact isolation and sound insulation, but its essence is rubber, and rubber is susceptible to temperature, oil, ozone, sunlight, etc. And chemical solvent corrosion, the function is easy to age and relax, so the service life is short. ...

AI Technical Summary

Problems solved by technology

[0004] Among them, the temperature has the greatest influence on the rubber shock absorber. It is well known that the rubber shock absorber is related to the hardness of the rubber. The hardness is high, the stiffness is large, the load is large, the hardness is low, the stiffness is low, the load is small, and the temperature will affect the hardness of the rubber. impact, that is, high temperature and low hardness, and vice versa, and the traditional rubber shock absorber has not set up a special treatment method for this, resulting in the shock absorption effect of the rubber shock absorber inconsistent with the expectation, so a stiffness can be Rubber damping equipment for adjustable engineering vehicles came into being
