Development of Low Friction Washer for AT·CVT (Torque Converter)

Various needle bearings and metal thrust washers are used in automatic transmissions (ATs and CVTs) for automobiles, however, in recent years thrust washers made of engineering plastics are begining to be adopted, because of their superiority in saving space, reducing weight and cost. This paper reports the newly developed low friction thrust washer made of engineering plastic for torque converters of AT·CVT.
