Arrangements for driving and steering of motor vehicles

Abstract From the Canadian patent

A transmission arrangement for an engine driven vehicle having two continuously variable transmissions serving to drive left and right hand vehicle wheels at separately variable drive ratios. Each transmission incorporates a variator of the type in which a net torque applied to the variator through its input and output is referred to a ratio control part which may be formed as a control lever whose position governs the , transmission's drive ratio. The control parts of the variators are each operatively coupled to a driver's speed control such that the speed control , determines a mean position of the two control parts. However they are both also able to move relative to the mean …
