| contd :- -2- Thus for quick reversals of minute amplitude the frictional load is more effective than the spring controlled hydraulic damping, which is more constant over its whole range. The friction load gets easier once the steering has begun to turn on a lock, the hydraulic loading remains the same. We would not consider this difference to be worth much more than 10% under normal driving conditions. We appreciate that as at present fitted up, the effective load of the steering damper increases on a lock which is the reverse of what is desirable, due to (a) the angular movement of the lever (b) the cross steering tube approaching the axle. We minimise these features by making our observations on relatively small angular movements of the steering wheel. HS{Lord Ernest Hives - Chair}/W.A.Robotham. | ||
