We have tried a mock up of the improved steering geometry FD.{Frank Dodd - Bodies}199/200/201/205 on 7.B.V. The new geometry is a considerable improvement on the original layout but there is still some wandering on undulating roads. We have made some measurements which indicate that the geometry of the cross steering tubes is now very good but that the road wheels are deviated by movement of the outer ball pins due to bending of the yokes under the varying spring loads. We are trying to counteract this by altering the geometry of the cross steering tubes. In any case we prefer the new levers to the original and will probably wish to fit these to the 10,000 mile test Bentley III. Will you please have the schemes detailed. Some slight alterations will be necessary owing to the altered position of the rear torque arm rubber bearing and the altered heights of the cross steering ball pins which we are now trying. We have explained these to Da{Bernard Day - Chassis Design}/DB.{Donald Bastow - Suspensions} Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer} | ||
