| contd :- -4- to the method of lubrication and assembly, friction is a widely varying factor. If all side steering tubes fitted up with one strength of spring gave results which did not vary by more than 20%, we should consider this to be a reasonable variation. Therefore if we are to fit springs which are certain to make a marked difference to steering shocks, somebody is bound to consider that in isolated cases they are rather flexible for maximum selectiveness. Our tests in France indicate that really 1000 lbs. springs are the highest rating which produce a really marked reduction in steering shocks under all conditions; we recommended 1500 lbs. out of consideration for control. The whole question of the arrangement of the side steering tube, the best initial set up, the optimum travel to be allowed, and the best production method of obtaining consistency is now receiving attention. The actual spring strengths are only one of a number of factors affecting this particular steering feature. Hs{Lord Ernest Hives - Chair}/W.A. Robotham. | ||
