| -5- without these loads. We still consider that Timken bearings on the cam are preferable to the Adamant type parallel rollers, as there is less risk of variation of friction characteristics due to small errors in manufacture. It will always be beneficial to keep the mechanical efficiency of the geardown consistent with the necessary lightness of steering during shunting of the car. We have yet to try increasing the stiffness of the steering system on a 25 HP. chassis, so that we do not know whether resonance is occurring. The problem on this chassis is more complicated than on the Ph.III as the steering geometry is far from perfect. We have for trial an articulated side steering tube with an intermediate drop arm for giving perfect geometry. Hs{Lord Ernest Hives - Chair}/F.J.Hardy. | ||
