Abstract

The present invention includes a suspension apparatus as shown in figure 1 with telescoping tubular elements (30) and (60), and a mechanical spring (40) in parallel with an air spring chamber (50), positioned in one of the tubular elements (30), providing a mechanism for adjustment (48) of the air pressure, the weight of the apparatus, and resistance of the apparatus to compressive shocks.
