Bailey - Chief Engineer} c. to Da.{Bernard Day - Chassis Design} 4704 Hs{Lord Ernest Hives - Chair}/Gry{Shadwell Grylls}/9/KW.1.4.35. Rear Axles. We think it worthy of putting on record that, during the gearbox testing we have carried out on the Vulture car equipped with an engine giving an open exhaust torque of 400 lbs. ft., the 12 x 35 spiral bevel axle gears have completed 2 hours full torque running on 3rd, 2nd and 1st gears. This is the same amount as our usual axle test. No trouble has been experienced and the axle has remained quiet. Whitmore's oil has been used throughout. The stresses in this axle were thought to be about as high as could be used. The same gears have also done 9,000 miles road running, chiefly testing gearboxes, including full throttle ascents of test hills on 1st gear. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
