Design and Development of Wet Disc Brakes for Agricultural Tractors

A multiple wet disc braking system has been developed for the Allis-Chalmers Models 7030 and 7050 agricultural tractors. An extensive test program was developed, numerous friction materials were tested, and laboratory testing supplemented tractor testing so that all factors could be evaluated. The multiple disc brake shows promise for greater tolerance in the selection of friction materials to solve such braking problems as noise, fade, energy capacity, and torque capacity.
