ABSTRACT:
The invention relates to a center drive car, having conventional steerable front wheels and rear wheels. The center drive has either roller or paired wheel traction. These are mounted on a swivel, which is directionally slave controlled by the conventional steering. A small motor, either directly linked via a differential, or more preferably via a hydraulic circuit including a differential, drives the central roller or wheels. The swivel is preferably retractable, by a lifting device, which may be operator controlled, or speed controlled by a governor. The center drive can be used under limited speed conditions, in a vehicle for urban use, where it would be more economical than a conventional high speed engine. It can also be used in a conventional vehicle under limited speed conditions, instead of the conventional engine.
