Abstract
A skateboard is provided with trucks, each of which carries a plurality of wheels mounted in independent suspension. Longitudinally extending swing arms carry the wheel axles forwardly or rearwardly through a yoke mounted under the skateboard by a pivot connection and by a resilient support. The arms are resiliently biased by means of separate springs or torsion bars so that varying pressures across the skateboard platform alter the distance of the skateboard wheels from the underside of the platform and conversely roadway irregularities displace the skateboard wheels towards the platform independently one from another. In one embodiment the swing arms are mounted such that the wheel axles extend substantially across the axis of the resilient support.
