A Magnetic Powder Coupling for Multistop Vehicles

The replacement of clutch discs in vehicles that operate under stop-and-go operating conditions represents a bother-some and sometimes major service problem. As a means toward alleviating this situation, Eaton Manufacturing Co. has developed a magnetic powder coupling which can be used to replace the manually operated dry disc clutch located between the engine and transmission of multistop vehicles. This paper describes the design, development, and test installation of the magnetic powder coupling unit in medium and large range vehicles.
