ABSTRACT:
Bump stop for an amphibious vehicle suspension having a member selectively movable between an operating position, and an inoperative position. This allows the suspension to retract road wheels along locus for conversion to marine mode. Bump stop free end may be moved by filling cavities with pressurized fluid. Alternatively, the entire bump stop may be rotated on a pivot by a hydraulic cylinder, an electric solenoid, manually or by any other mechanical means. Alternatively, the movable member may be a position in a cylinder, withdrawn against a return spring by hydraulic pressure, and may act against resilient snubber on the vehicle suspension. Bump pad has a curved undersurface, allowing the bump stop to be bent out of the way when the suspension is lowered.
