R.R. & Co. Ltd. G.S.D. 18.2.13. COPY. COPY. X168 To De from R.{Sir Henry Royce} Copy for Wor.{Arthur Wormald - General Works Manager} R11/P 25.9.13. Confirmation of telephone messages of to-day :- Re Steering Pivots, one 4 1/2 degrees and one 3 degrees wheel pushed on. The pivot joint can be shortened at the top to bring stub axle central. Only trouble I can see is difficulty of lubricating the bottom pivot joint without removing wheel " see other suggestions. Re Lay-out. Make the ball joint well clear of the wheel spokes. I think it would be slightly advantageous if the wheel were 2 1/2° instead of 3°, and the pivot were 5° instead of 4 1/2°. This would make it slightly more self-righting and be slightly better for the tyre. This arrangement so reduces the shocks that I think the cross steering tube with its spheres can remain the old standard dimension. R.{Sir Henry Royce} Stub axle should be put in hand at once 7 1/2 to 8° inclination. Also axle forging. Steering arms should be nicely round and smooth so that there shall be no over stressed edges. | ||
