| contd :- -2- especially if it necessitates pulling into the side of a highly cambered road to do so. In order to minimise this effect a side steering tube fitted with stronger and equal buffer springs, as used on the latest outside pendulum lever type of steering, was tried in conjunction with this steering - giving the steering (c). This effected a noticeable improvement, the steering at once being slightly more positive and stable at high speeds, while not appreciably increasing road shocks transmitted to the steering wheel. Apart from this improvement it was definitely appreciated that any tendency towards low speed wobbles was very considerably reduced after fitting the stronger buffer springs. The steering (b) even when fitted with the latest friction device on the off-side pivot could be made to wobble at low speeds, (14 to 16 m.p.h.), but after changing over side steering tubes and fitting the stronger and equal buffer springs, this wobble could not be obtained; the steering has altogether a better feeling in this respect. It was definitely established that the steering (c) is a decided improvement over (b), and that in consequence the old type of side steering tube and buffer springs should not be used with this steering. The following are particulars of the buffer springs used in each case :- contd :- | ||
