Abstract:

A wheeled vehicle includes a front steered wheel, a rear driven wheel, and a support member that supports a rider. A main structural tube is disposed substantially horizontally along a longitudinal axis for supporting the front steered wheel at a forward end of the main structural tube, for supporting the rear driven wheel at a rear end of the main structural tube, and for supporting a rider who controls and steers the wheeled vehicle. An improved torsion acting shock absorbing mount is disclosed for the cantilevered shock absorbing support of at least one of the vehicle wheels from the frame. The torsion acting shock absorber includes a square sectioned metal tube, a correspondingly square sectioned metal shaft, and confined compressible resilient compound rods acting there between. The torsion acting shock absorber is attached at right angles to the main structural tube. A cantilevered wheel support is mounted offset from the main structural tube at the end of the shock absorber remote from the main structural tube. The square tube fastens at right angles to the main structural tube while the square metal shaft connects to the cantilevered wheel support. The cantilevered wheel support torsion rotates through the shock absorber at right angles with respect to the main structural tube to undertake shock absorbing movement between at least one of the wheels and the main structural tube, and the rider.
