Steer-Drive  

The Torvec Full Terrain Vehicle (FTV™) bridges an important gap between wheeled and tracked vehicles. This new vehicle combines the high-speed capabilities of trucks and cars with the high-traction capabilities of tracked vehicles.

Steer-Drive Design
From U.S. Patent #6,554,729

The patented design of the FTV™ required a unique steering system. Most tracked vehicles are steered employing either "skid steering" or hydrostatics. Torvec has designed a revolutionary steering system which is hydromechanical, and allows the vehicle to be steered using a conventional steering wheel. The result is a traditional driving experience in a most unconventional vehicle.

The FTV™ steers as easily as a truck through the use of a steering wheel. The steering is accomplished by changing the relative speeds of the two tracks. For example, when moving straight forward, both tracks are moving at the same speed; when turning, the inside track slows down while the outside track speeds up proportionately. The vehicle turns in the direction of the slower track. Our unique steering mechanism separates the mechanical function of driving the vehicle forward for high speed, from the steering function, as needed. The two functions operate independently and simultaneously.
