Abstract
A power transmission and steering apparatus for vehicles includes an engine coupled for rotating a pair of coaxial, spaced-apart driver wheels formed of a low durometer plastic material. A pair of discs are positioned in an opposed, spaced apart relation and adjacent to the peripheries of the driver wheels and one being on each of the opposite sides thereof. The discs are each coupled to a different one of the vehicle drive wheels, and each disc is mounted for rotation on a pivotable shaft. Independent control levers are coupled to each disc for independently tilting the same into engagement with a selected one of the driver wheels for rotation in one direction upon engagement with a first drive wheel and for rotation in the opposite direction upon engagement with the other driver wheel, the speed of rotation being controlled by the pressure between the disc and the driver wheel.
