| TO HS{Lord Ernest Hives - Chair}/RM.{William Robotham - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} ORIGINAL DA{Bernard Day - Chassis Design}1/M5.11.26. X8300 X9425 X8420 X8430 X235 FRICTION IN NEW FRONT AXLE. With reference to your proposal to increase the friction on the ball ends, increasing the dia. of the ball so as to keep the unit loading about the same as on the original spring loaded cross steering tube, R.{Sir Henry Royce} does not care for these spring loaded ball ends in any form, but hopes that you will hurry on the hydraulic shock damper with a view to getting that on as soon as possible. With reference to the friction in the steering pivots we should be much obliged if you would try an experiment on the lines of N. scheme 2296. which we send herewith. It will be seen that we suggest inserting a spring in the multi plate clutch so as to shunt part of the weight directly to the bottom plate by using a suitable strength of spring. It seems to be possible to obtain any friction in this way - from the original friction, without extra plates, to 3 times the friction (as originally instructed on N. scheme 2254). In addition to this a part of this friction, the amount depending also on the spring strenguh, is retained when the wheel flies into the air. DA.{Bernard Day - Chassis Design} | ||
