| -3- (10) "Swing axle" effect in the front wheels (i.e., change of camber) undoubtedly promotes high frequency wheel fight. A flexible frame has the same effect. This effect, which depends on gyroscopic action, is less harmful on Dubonnets because of their inherent tendency to pick up the low frequency type in preference to the high. (11) Devices like the shimmy shackle or Mercedes wheel-mount obviously "tune-down" the steering in two ways, by added flexibility and by increasing the oscillating masses. It appears therefore that for a given addition of "rubberiness" to the steering they are more effective than a simple addition of flexibility to the pitman arm. Rubber-mounted lower wishbones on our present suspensions are effective in this way. (Sgd.) Maurice Olley. | ||
