| E ) FROM DA.{Bernard Day - Chassis Design} BY.{R.W. Bailey - Chief Engineer} ) C. to Mr. HS.{Lord Ernest Hives - Chair} LID{A. J. Lidsey} DA{Bernard Day - Chassis Design}2/W15.4.32. x433 x5410 J.{Mr Johnson W.M.} 3. - SPRING CONTROLLED REAR SHACKLE FOR FRONT SPRINGS. Herewith are N. schemes 3453/54., alternative suggestions for the flexible shackle on the above car. Because of the short distance between the frame and the spring eye, an arrangement exactly like N. scheme 3452. (for P. 2.) does not seem possible. N. sch. 3453. is very much like it, but the pads supporting the springs are not exactly normal to the movement, so that there is a little lateral bending of the springs, which is negligible on the P. 2. scheme. N. sch. 3454. is an alternative with this feature reduced. The spring stress in both cases is a maximum. We think we prefer N. sch. 3453. as being more compact and conventional. The drawing is for the L. H.{Arthur M. Hanbury - Head Complaints} car but is of course easily adaptable to R.{Sir Henry Royce} H.{Arthur M. Hanbury - Head Complaints} The 25HP. is still shorter. The spring negative camber may have to be increased. DA.{Bernard Day - Chassis Design} | ||
