Gas shock absorbers

Examples of advanced technical solutions in gas shock absorbers:

1. Valve system that reacts to the speed of the vehicle.
A multi-stage valve system allows the properties of the shock absorber to be adapted to road conditions (type of surface, travel speed). When driving slowly on an even surface, the valve system allows the shock absorber to work freely (compression-stretching). During dynamic driving and worse surfaces, the shock absorber is compressed faster. Thus, the damping medium is compressed faster. The valve system guarantees an immediate response from the damper, "Stiffening" of the suspension, ensuring constant contact of the tire with the ground and full control of the vehicle.

2. Sintered piston and piston rod guide
Sintered metals provide much greater durability than other traditional materials, increasing the shock absorber's resistance to wear and extending the service life.

3. Single tube design and free piston
In single-tube gas shock absorbers, a free piston separates the oil and the compressed nitrogen. Thanks to this, the phenomenon of foaming of the damping agent was eliminated, negatively affecting the shock absorber's work under high loads

4. Piston rod superfinished, case hardened and chrome plated
Even the smallest imperfections on the piston rod surface can cause premature wear of the oil seal – the most common cause of damage to a shock absorber.

5. Jointless housing cylinders (seamless pipes) and mounting brackets Most tubular shock absorber housings and mounting brackets are obtained by forming a sheet metal cylinder. The place where the edges of the sheet forming the cylinder are joined (spaw) is one of the weakest points of such a shock absorber. Low fatigue resistance and high loads may lead to breakage of joints and complete destruction of the shock absorber. Housing cylinders as well as shock absorber mounting brackets are pressure extruded, so they are not connected anywhere. This means that there are no weak points whatsoever.

6. Multi-lip sealants
To ensure operational reliability, the oil must not leak out, and the contaminants cannot penetrate into the working space of the shock absorber. Multi-lip sealants, ensure proper working conditions of the shock absorber.

7. Special design control valve
Particularly severe operating conditions can mix the oil with the gas and cause foam inside the shock absorber, significantly reducing the effectiveness of vibration damping. A control valve used in gas shock absorbers of a special design to minimize the foaming phenomenon, which ensures proper operation even in difficult road conditions.
