Bailey - Chief Engineer} PN.{Mr Northey} R2/M6.10.26. STEERING WOBBLES. X.235 X.457 X.8430 If we can eliminate low and high speed wobbles by the use of the new axle, and by the hydraulic shock dampers between the axle and the frame, and the hydraulic damper on the steering, then perhaps we can increase the lean of the front pivots sufficient to make the steering less dangerous and so do away with the risk of it taking charge. The critics are making it very difficult to meet all their wants, because the self-righting prohibits our going further with irreversibility. Irreversibility is a [strikethrough]konkret[/strikethrough] source of security against road shocks etc. It has occurred to me that it is just possible we might get the self-righting by a suitable spring on the worm shaft. This spring would be set to give no force in a position of straight steering, but would return the worm to this position after KAM cornering, independent of the road wheel re-actions. We will instruct something to try this suggestion out. It might be a patentable scheme. R.{Sir Henry Royce} | ||
