Improving steering systems by incorporating friction and spring centering to reduce road shocks and wobbles.

However, increasing the dimensions of the worm and nut should result in consistency over a greater period.

We are convinced that we can demonstrate that friction incorporated on the steering wheel side of the side steering tube springs is more effective than anywhere else in the steering system, provided always that low speed wobbles have been otherwise dealt with by damping on the axle. Our explanation is that in this position friction makes the side steering tube springs do more work when absorbing shocks, and less work when the car is being steered, result - greater freedom from road shocks and less sponginess.

We believe spring centering would improve the effect. On EAC.V11 the lightness of the steering when shunting due to the decrease in weight over the front axle with the alum: engine, is agreeably pronounced.
