摘要：
In order to reduce the friction and wear between the friction plate and the pulley of the metal belt type continuously variable transmission (CVT) and enhance the transmission efficiency of the CVT, a magnesium alloy material with wear resistant coating by heat treatment is proposed to replace the bearing steel material for friction plate. It is founded by finite element simulation analysis that the friction plates of different materials have a significant influence on their contact stress and a certain effect on their stress distribution. The centrifugal force generated by magnesium alloy metal belt has much less effects on the system than that generated by bearing steel metal belt. The results of experimental study show that all three wear resistant coatings prepared on the surface of magnesium alloy can enhance its wear resistance, and hence reduce the friction and wear between the friction plate and the pulley and extend the service life of the metal belt of CVT. © 2020, Society of Automotive Engineers of China.
