| -3- at low speeds. This is quite natural because one is riding on a Hydraulic machine instead of resilient springs, yet when a customer complains of hard riding, our thoughts fly to weaker springs whereas the opposite may be the cure with reduced S.A. loadings. I must say here that I am adopting an opinion that our springs now that they are well lubricated are too flexible. I should like to have an opportunity of experimenting with springs which reduced deflection for a given load. I do not mean a heavier spring, but rather one which has less up and down movement. I also think our Hydraulic Shock Ansorbers do not offer sufficient damping even when set up to 80/100 or 100/100. I should like to have authority to fit a double friction damper in instances where the circumstances appear to call for damping out violent rebounds. Ps. | ||
