| - 19 - a clip for every leaf as will be observed by the illustration of the Lancia rear spring. There are a number of other types of clip used to prevent the spring leaves separating on the re-bound, some of which undoubtedly increase the internal spring friction. It appears to us that the principle of reversed leaves or any other device for increasing the internal spring friction is wrong because the friction so obtained is difficult to measure, difficult to control and bound to vary enormously with the life and condition of the springs. It is possibly the failure to obtain a reliable and adequate friction damper which will not wear out rapidly on the worst continental roads which has caused the reversed leaf spring to be evolved. [IMAGE CAPTION] LANCIA LAMBDA SPRING (e) Anti-rolling devices. There are several ways of preventing a car rolling on corners. The general principle employed is to restrain the motion of one spring relative to the other, but to leave them free to work together. Considering the sketch of the hydraulic arrangement - when the axle moves parallel to the frame, liquid passes from one cylinder to the other via the connecting pipe and sets up little or no resistance to the motion. When any tendency to roll occurs, however, and one side of the frame rises while the other falls, oil in each cylinder is forced through the holes X which can be contd. | ||
