Abstract:
1. An arrangement for driving and steering a motorised vehicle, the arrangement comprising: a right hand drive arrangement for driving a right hand vehicle wheel at a speed which is continuously variable through a range including forward and reverse speeds, a left hand drive arrangement for driving a left hand vehicle wheel at a speed which is continuously variable through a range including forward and reverse speeds, a driver actuable speed control, and a driver actuable steering control, wherein both the left and right hand drive arrangements are controlled, in dependence upon driver inputs, by means of the speed and steering controls acting either through a common mechanism or through two mechanisms, where the common mechanism or each of the two mechanisms comprises: wherein movement of the speed control in a first direction causes an increase in the speed of both the left and the right vehicle wheels, movement of the speed control in a second direction opposite to the first causes a decrease in the speed of both the left and the right vehicle wheels, so that vehicle speed is controllable by means of the speed control when the vehicle is steered straight, and movement of the steering control causes a change in the speed of one of the left and right vehicle wheels relative to the speed of the other to provide for vehicle steering.
