ORIGINAL Hs {Lord Ernest Hives - Chair} /AJE/L619.8.26. GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) III. STEERING. V5750 X5450 Comparative tests between the following types of steering. (a) The original India(Production 20 HP. with 4-speed box and Front Wheel Brakes) and present standard steering. (b) Conversion steering to N.sch.2062 i.e. .700 lead, large diameter worm in standard steering box. (c) As (b) but with side steering tube fitted with stronger and equal buffer springs as used with the latest outside pendulum lever steering. Direct comparison tests between the original India(Production 20 HP. with 4-speed box and Front Wheel Brakes) steering (a) and (b) show a very definite advantage in favour of the lower geared steering. At high speeds over rough roads, the shocks transmitted to the steering wheel are very definitely decreased but are not eliminated. A long test over very bad winding roads, on loose surfaces and potholes, showed up the advantages of the lower geared steering (b) - there was greater immunity from road shocks, easier steering when shunting or cornering on highly cambered roads combined with an increased general stability were definitely appreciated. When travelling at high speeds on wavy or highly cambered roads, the steering (b) has a tendency to wander, con-stantly requiring checking; it is scarcely positive enough in this respect. This fault is not glaringly bad, but is suffic-iently in evidence to cause the driver slight uneasiness if he attempts to pass other vehicles at high speeds. contd :- | ||
