Eric Platford - Chief Quality Engineer} R1/M16.10.22. RE. SPRINGS FOR ABROAD X.2628. X3461 Referring to your BJ16/H26.9.22., if my memory is right we generally spring our cars for less than the maximum weight, that is to say when the car is fully loaded, it is down at the back below the normal position, but owing to the ample clearance we allow on the rear bump in England this causes no trouble. When however we are dealing with extremely rough roads we may find that the car strikes the buffers too frequently. I quite agree with springing the cars for nearer their maximum weight; possibly 10% is not too much but I would like the Works to consider 5%, especially now that we are fitting shock dampers to the rear of the car. Naturally the shock dampers would do very much towards avoiding the trouble without altering the strength of the springs and this should be considered when settling on the amount. I think it would a be quite feasible to try 5% with the shock absorbers for the time being. I very much fear going too far as it spoils the riding of the car. R.{Sir Henry Royce} | ||
