ABSTRACT:
The present invention provides a suspension for a conveyance that is capable of traversing obstacles and rough terrain. The suspension includes a frame, a pivot arm, a front caster, a drive assembly and a rear caster. The pivot arm substantially remains in a first position when the drive assembly moves in a first direction. Movement of the drive assembly in a second direction urges the pivot arm away from the first position.
