Tests are described and actual traffic accident situations are recounted where school buses equipped with Mor/ryde rubber spring suspension systems did not rollover when they would otherwise have been expected to do so. The details of this suspension system are described. The two outstanding features of this system are, first, the utilization of rubber blocks that are sandwiched between the axle and the rim, and second, the complete elimination of the rear leaf steel springs. Three main benefits are seen in this system: (1) safety--drivers enjoy better control, have constant wheel-to-road contact, and the bus is virtually roll-proof; (2) softer, smoother ride qualities stemming principally from the absence of metal-to-metal contact between the road and the bus body; side-to-side rocking is greatly reduced, and there is minimum tipping of the body while cornering; and (3) since all moving parts are rubber or rubber-insulated, they require little or no maintenance.
