Abstract

See full text

An electrically powered vehicle achieves maximum structural strength with minimum weight by utilizing a combined body and chassis formed entirely of plastic material, molded and bonded into an integral composite structure which includes a central, hollow longitudinal beam, top, bottom, and side panels of the vehicle body portion, and a power unit supporting chamber at the forward end closing the forward end of the beam and tying it to the side panels. The beam holds the batteries, and the chamber contains all of the components of the power unit including the controlling device. The structure is thus as rigid and light as possible, in addition to eliminating any possibility of any unwanted grounding or electrical paths. The only metal in the vehicle is that of the additional components such as road wheels, suspension members, steering, and power unit and the fasteners and brackets used to retain them in mounted position.
