Trends in Wet Clutches Contributing towards Carbon Neutrality

Abstract

Wet clutches are mainly used in automobile automatic transmissions. To reduce greenhouse gas emissions, it is important to improve the fuel efficiency of automobiles. Wet clutches are required to reduce the drag torque when the clutch is disengaged. Drag torque varies greatly depending on the design of the clutch plates, represented by the shape of the friction material segment pieces. It will be explained the efforts to reduce drag torque related to the design of friction plates.
