| contd :- -9- SUSPENSION - Summary. Summarising results of various tests, the main difficulty with independent suspension of all four wheels would appear to be lack of lateral ex stability. If the car is arranged so that it will not roll, the independent movement of the wheels is impaired, and the benefits of the suspension are lost. A practical compromise, somewhat better than the present method of springing cars appears to have been obtained by Lancia and Ansaldo, who combine widely spaced semi elliptic springs giving good lateral control, with abnormal front springs. We do not consider that either of the two cars tried with fully independent wheel suspension had made the best of the scheme at their disposal. It appears to us that with suitable modifications the Cottine Desgouttes could be made into a well-sprung car. Hs{Lord Ernest Hives - Chair}/W.A.Robotham. | ||
