X.891. X.1242. Front Axle. This should be as near as possible centre point steering, and if this gives any inclination for a steering wobble, or want of stability at high speeds or low speeds. I have suggested that the thrust bearings on the steering pivot on the axle should be fitted with plain thrust washers of vulcanized fibrem instead of ball thrust washers - Such steering wobbles appear to be increased by blowing up the tyres very hard. The forgoing assumes, of course, that the inclination of the steering pivots on the axle are inclined backwards the correct amount for good high speed steering, which please include on your report. X.3461a. The front axle is to be fitted with the shock dampers as previously . They should be tightened through a bdg range to find the possibilities of the adjustment, that is, one would tighten them more and more until some disadvantage was found, such as causing vibrations to the front of the chassis at slow speed. It will be noticed that the front of the chassis at high speed will be steadier the more these are tightened. R.{Sir Henry Royce} | ||
