Abstract
A self-righting rolling suspension system is disclosed which has two ground contact zones and has self-righting stability in perpendicular planes, one of which includes the contact zones and one of which is perpendicular thereto. The system includes rolling support members that may be discs, annuli, cones or similar bodies of revolution. With the preferred orientation of the rolling supports, an effective radius several times the actual radius of the rolling support results. A self-adjusting differential is also obtained from one application of the principles.Shock absorbing and braking assemblies can also be incorporated in the system.
