ABSTRACT:
An electric vehicle of adequate performance and range and of low cost uses a long tray of batteries easily rolled into or from a housing which also comprises a structural backbone of the car. The body provides useful space, such as a passenger compartment on both sides of the backbone, extending down to about the level of the bottom of the backbone, thereby keeping a low center of gravity, and compactness for low wind resistance. The steering wheel is on a swing-arm standing out laterally from the backbone, the backbone supporting the steering shaft in a position not "aimed" at the driver. The steering arm swings out of the way to facilitate access, and in one form of the invention the body top swings open and there are no side doors. Separate V belt drives from the motor through automatic speed-changing pulleys for each side minimize current draw on start-up and acceleration, maximize performance, ensure driving both drive wheels in slippery weather, and permit differential wheel speed on turns. Independent suspension of the drive wheels ("knee action") without universal joints is achieved by using the flexibility of the V belts to permit the driven pulley to rock out of alignment with the drive pulley.
