Abstract

An auxiliary solid rubber tyred wheel 8 is fitted on an arm 6 which rotates round a horizontal axis, just like the normal wheels. The bearing is itself free to rotate about a vertical axis 5. The arm is pulled sideways by a spring 11 fitted to the chassis at one end 12 and partway along the arm 10 at the other. When the vehicle is at rest the wheel is pulled sideways till the spring hangs loose, dotted position. A contact pin touches a blade 14. When the vehicle moves, the wheel tends to align itself with the vehicle axis, and when successful another contact is made and a safe indication given. Too much ice, etc makes the ground slippery and the wheel cannot maintain its position, the other contact is made and a suitable warning is given to the driver.
