The cross link KL slides in the bearing and carries pin at its end K and L. The slide blocks are pivoted on these pins and move with turning of bell crank levers as the steering wheel is when the vehicle is running straight, the gear said to be in the mid-position. The short arms AK and Bl are inclined at angle of alpha+90 to their stub axles AC and BD. The correct steering depends upon a suitable reaction of cross-arm angle alpha, and is given
