ABSTRACT:
The speed of a driverless vehicle is controlled along the length of the module from an incoming high speed to an outgoing low speed or vice versa. The module includes first, second and third aligned drive tubes between tracks adapted to support a vehicle. A first motor is coupled to the first drive tube for driving the same at a first (high) speed. The second drive motor is coupled to the third drive tube for driving the same at a second (low) speed. The second drive tube is maintained out of mechanical engagement with the first and third drive tubes. A variable speed motor is coupled to the second drive tube to drive the second tube between the first (high) and second (low) speeds, independently of the first and second motors.
