L. Edwards} Mr. W. A.{Mr Adams} Robotham, c/o Rolls Royce, Limited, Derby, England. Dear RM{William Robotham - Chief Engineer}: Yours of May 31, 1934. Rubber bushings in spring shackles and wishbones, re- duce tire noise and also reduce shock. That is, vibrations of high frequency down to say at a guess, 1000 c/min are cushioned or absorbed. Front roll stabilizer we think is better than rear at least in some ways. It appears to reduce the small or incidental motions of wheel fight (probably by keeping the wheels on the ground better). If the car nose has a frequency such that true shimmy may occur I have the hunch that the front stabilizer, by raising the wheel hop frequency, may actually make the condition worse. There appears to be better handling with front sta- bilizer though this is difficult to describe. It avoids a con- dition when braking on a high speed turn where the rear stabili- zer in cars like the Airflows may actually lift the inner rear wheel off the ground. On the other hand the rear axle is definitely more inclined to hop with stabilizer removed. Sincerely, Maurice Olley Maurice Olley M.{Mr Moon / Mr Moore} Olley H | ||
