The characteristics of air spring
| (1)The elastic coefficient of air spring is variable. |
| (2) the air spring rubber body is relatively light, the quality of air is also very small, the weight of the air spring comes mostly from the upper cover and the lower cover, unlike the steel spring, the metal is heavier. |
| (3) The bearing capacity of the air spring can be adjusted according to the size of the inflation pressure in the rubber bag. For the same air spring, the size of the inflation pressure can be adjusted to meet the needs of different bearing capacity. |
| (4) Because the air spring takes the air as the elastic medium, when compressed, the internal friction is small, so the vibration isolation effect is better. In addition, the air spring has a good ability to eliminate noise, because the ability of air and rubber to transmit sound is relatively weak. |
| (5) the fatigue resistance of air spring is relatively strong, the experiment shows that: under normal circumstances, the stress cycle number of leaf spring can withstand is 500,000 to 600,000 times, and the general air spring can reach about 3 million times, and the stress cycle number of high-quality air spring can withstand can reach more than 5 million times. Therefore, the air spring has outstanding effect in resisting strain. |
Airbag for heavy truck lift axle
Modern heavy trucks have higher and higher requirements for lightweight, fuel-saving performance and comfort. The lifting axle is the time to play its role. It can be lowered to carry the weight when it is heavy, and the axle can be lifted when it is empty. Lifting, the tires of the lifting axle have no frictional resistance with the ground, which can reduce the fuel consumption. Coupled with the comfort of the airbag suspension, the airbag lifting axle has become a must for high-end models.
Working principle:
The lifting airbag is mounted on the U-shaped bracket, the U-shaped bracket is connected with the frame, and the lifting airbag is connected with the axle.
When the axle needs to be lifted, the lifting airbag is inflated, the 4 shock-absorbing airbags are deflated, and with the U-shaped bracket as the support point, the airbag just like the jack lifts the axle to realize the lifting of the axle.
