| To De. From Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} C. to EY. 47420 Hs {Lord Ernest Hives - Chair} /Rn {Mr Robinson} 2/T19.4.29. RE CROSS STEERING TUBE. 47425 With reference to your Da {Bernard Day - Chassis Design} 4/M17.4.29, without brake application there is no doubt that the cross steering tube would not foul the dampers. When we pull the axle down to the chassis there is plenty of clearance. As we believe we once demonstrated to you, however, when maximum braking is indulged in, the rear of the front spring is buckled, and the axle comes back a little while the cross steering tube rises. This is because the back of the rear spring cannot withstand the amount of compression it gets. We think that 22-EX running in France has developed too much front braking which may have accentuated the trouble. Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} | ||
