3B12-304 Goodyear Air Spring Genuine Triple Convoluted Cross to Firestone W01-358-8013

Instructions of air spring:

To ensure stability, the distance from the floor to the center of gravity of the load should not exceed the shortest distance between the air springs.
The air spring has almost no lateral stability. Therefore, a laterally stable fixation must be added. The path of motion must be guided because the air spring provides almost no lateral stability.
Only pressurize the air spring when it is loaded.
An external extension stopper is required to limit the extension of the air spring, so that it is not easy to damage the air spring.

Goodyear® Goodyear air spring features

Goodyear® Goodyear air springs utilize the compressive elasticity of air, and are essentially different from metal springs such as leaf springs. It has excellent characteristics as a suspension spring. For example, the combined use with a control device keeps the height of the vehicle always constant or arbitrarily changed. It can also improve the vehicle's inclination by individually controlling the left and right air springs.

Modern road transportation places high demands on the comfort and efficiency of automobiles. STEMCO (Stemco) company's mission is to "make our roads safer", knowing user satisfaction, easy and comfortable user experience, is the foundation of the product, and fully consider commercial vehicles in product design The demanding requirements of trucks and customers, such as its super-buffered air springs, use the materials and design of the load to provide industry-leading vibration damping, light weight and long service life. In addition, the unparalleled comfort performance design makes the super-buffer air spring reduce driving fatigue, reduce parts wear and tear, shorten the failure time, and thus improve safety performance.

One of our America customers explation:

I have not explained the function of the air spring better. The clutch I sent to you as an app did not get enough instructions to work properly. Both torsion load and air spring function. It turns out that the function of the first sample is as expected, the horsepower is less than 150 HP, and there is air pressure to stabilize the air spring. I don't have any problems with the torque requirements, because the torque requirements of the prototype I developed are not a problem. My current request from potential customers is to increase the horsepower applied to stabilize the air spring without applying air pressure. This request caused problems with my design. I believe that with your help, we can create a startup program that meets the requirements of the new application.

I think your method of changing the direction of the wires is a good solution. The increase in the number of layers will also help. If the compression load increases due to the increase of multiple layers, I can use an air spring. If the increased torque requirement is met, I will be able to use the improved protective cover (perhaps an improved function) in all applications. I know this is not universal, but the interest in design has become very strong. I hope to use boots that exceed the safety factor requirements to meet the new requirements (twice the original design).
