| To.Bw. from E. {Mr Elliott - Chief Engineer} c. Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} re Turner-Faudi Suspension Unit. There will be a car here next Thursday at 10.30 a.m. fitted with the Turner-Faudi suspension, and I should be glad if you would examine this and try it. The suspension is completely independent on all four wheels, but the chief point of interest is the spiral springing combined with air springing and damping, as shewn on the attached blueprint. Apparently as far as can be seen there is a double acting piston with a leak hole in it working with a cylinder, and the effect is to produce an air spring with increasing amplitude of movement which probably alters the spring rating and prevents the vehicle from getting into a periodic swing. A certain amount of damping is probably also provided by the air leak through the piston but for small amplitudes of movement there is obviously no effect at all. Personally I do not attach much importance to the Faudi suspension but think that we ought to try the car. The curves on the print show a comparison with what is called normal suspension and are therefore valueless. ATT: E. {Mr Elliott - Chief Engineer} | ||
