| TO BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} SECRET. DA{Bernard Day - Chassis Design}1/M26.6.24. Copy to - EH. HS.{Lord Ernest Hives - Chair} E.{Mr Elliott - Chief Engineer} A.{Mr Adams} C. 11. FRONT AXLE. X8421 We send herewith N.scheme 1811., shewing a scheme for adapting double radius rods to the front axle control. When this drawing was begun it was intended to make a few modifications to the whole front axle to get rid of one or two points considered not quite perfect, but this policy has been subsequently changed, and a new axle will be sent shortly dealing with most of the troubles. In the meanwhile Mr. Royce would like the Exp. Dept. to test the double radius rods which are indicated on this drawing. They would have to be rigged up in a temporary and experimental way, preferably using an existing axle. We would like them to be tried with double rods as shewn, and also using the spring as one of the radius rods and the bottom rod shewn on the drawing as the other. We know Mr. Hives has tried a scheme something of this kind but we would like it tested approximately in the positions indicated on N.sch.1811. The rear bracket for the radius rods could be temporarily of stout plate with the ball ends projecting from it, and it should be placed well back near the steering box. The brake drum pivot and outer end of front axle shewn on this drawing are not to be worked to as they will not now be correct. DA.{Bernard Day - Chassis Design} [Stamp] RECEIVED 28 JUN 1924 | ||
