| 20110053731 | Arrangements for Driving and Steering of Motor Vehicles - 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 position, under the influence of the torque they react. Additionally the control parts are coupled to each other such that any displacement of one control part from the mean position is accompanied by an opposite displacement of the other control part. In this way the transmissions are enabled to the relative speeds of the driven vehicle wheels automatically to reduce or even eliminate wheel slip, whilst still providing the driver with control over overall vehicle speed. | 03-03-2011 |
