The investigation of effects of surface grooves on friction disc on drag torque and heat dissipation in wet clutches
The friction pairs in wet clutches can cause drag torque and associated energy loss,when friction discs are not engaged,due to the viscous fluid nature of the lubricant subjected to relative motion between the friction pairs.This phenomenon is detrimental to the service life of wet clutches and causes concern of risk.In addressing this issue,based on the Navier-Stokes equation,a total of 12 groove designs with 24 configurations are designed and analyzed by means of finite element numerical simulation to explore the methods of reducing the drag torque and energy loss.The results show that the combination of spiral groove and radial non-slot design has good cooling effect and high dynamic friction coefficient.This paper provides an important reference for the design of friction pairs oil grooves,which is of great significance for guidance.
