Wet Clutch Friction Material: The Surfaced Groove Effect
Grooves are either machined or molded into the friction material to improve the performance of a wet clutch by enhancing the ATF (automotive transmission fluids) flow rate, thus providing a means for better dissipation of heat during engagement. Grooves can also improve friction and wear characteristics as well as durability.
A disk-type wet clutch is an important component of an automatic transmission. Wet disk clutches are designed to provide adequate torque for the transmission of power from the driving member to the driven member during operation. A wet clutch pack consists of a series of separator and core disks to which friction-lining materials are bonded. The core and the separator disks are arranged alternately to a clutch hub that accommodates axial actuation and hydraulically presses the disks together. A wet clutch is immersed in...
