In two-wheel vehicles, single-tube shock absorbers are frequently used. A suspension strut with a progressive spring has been used. Blowing or discharge of nitrogen into/out of the compensation container changes the attenuation (hard, soft).
The following can be shown:
- Compression by pressing on the suspension strut
- Device to change the spring hardness by turning the stepped sleeve on the bottom of the suspension strut of adjusting nut
- Movement of the cutaway work piston with finned valves for the pusher and tractor phase
- In the cutaway compensation container, the cutaway dividing piston (rubber membrane), in which the gas cushion can be found, can be seen.
