ABSTRACT:
A shock absorbing device is disclosed, allowing reducing the vehicle weight at least by half. The device includes a tubular housing (TH) and within it a resilient shock dampening assembly (SDS) elastically axially movable is secured, through one or more inter coiled preliminary extended tension coil springs 6 and (6a). (SDS) also is locked to (TH) by a locking ring (8), in order to preserve said preliminary extension. (SDS) includes a plurality of telescopic sections, (UTS), (ITS2), (ITS1), and (LTS), resiliently supported by a plurality of compression coil springs (1), (2), and (3), interposed between them, designed to absorb average shocks. When the greater shock forces after entirely compressing the springs reach their predetermined unlocking level, rather than bottoming, ring (8) is opened, allowing the (SDS) to extend axially upward, opposed by springs (6) and (6a). Thus the (SDS) absorbs upward extensions and prevents the shocks to the vehicle's frame which would otherwise occur when a conventional shock absorber "bottoms out," because of its limited absorbing height. Since the respective wheel overcomes the obstacle, the force of the preliminary extension of springs (6) and (6a) returns the (SDS) for locking.
