Mechanical Interface for an Electric Propulsion Test Bed.

Abstract

As a result of the test bed/MERADCOM dc propulsion system optimization process, two configurations appear to be reasonable choices from a performance standpoint. The fundamental differences lie in the placement of the driver axle and electric propulsion system components. The rear wheel drive configuration is considered the optimum primarily due to a slight performance advantage. Highlights of both configurations are: Two speed involute tooth form electro-mechanically shifted transmission, 10:1 primary drive ratio and 5:1 final drive ratio; High capacity drum brakes with regenerative brake coupling; de Dion drive axle suspension with independent coil or torsion spring suspension on non-drive wheels (battery trays integral with suspension support frame); Radial construction tires; Four occupant interior capacity; 229-239 centimeter wheel base; Virtually no requirement for routine maintenance; Conventional occcupant safety equipment retained; Performance capability exceeds the requirements of the SAE; J227a schedule 'D' driving cycle with either 108 volt dc or 132 volt dc electric propulsion systems.
