Friction plates are the actuators, relying on hydraulic pressure and lubricating oil to operate, directly responsible for power transmission and interruption. The main clutch support is the core carrier, providing structural support, power transmission path, and lubrication and cooling oil passages. The lubrication valve is the control center, ensuring precise piston movement and sufficient lubrication of the friction plates by controlling oil pressure and flow. These three components form a closed-loop system: Lubrication valve failure → Abnormal oil pressure in the support → Friction plate burnout → Metal debris contaminating the oil → Further damage to the lubrication valve/support oil passages, creating a vicious cycle.

Friction Plates (Clutch Friction Plates/Discs)

Function: Alternating with steel plates (Steel Plates/Driven Plates), they form the clutch assembly.

Core Function: To transmit or disconnect power. When the hydraulic piston pushes the friction plates against the steel plates, friction transmits engine power to the gearbox system; disengagement interrupts power (used for shifting or neutral).

The surface is covered with a special friction material (such as paper, carbon fiber, sintered metal), requiring a balance between lubrication and friction.

Main Clutch Hub/Drum/Retainer

Function: Physical Carrier: The core skeletal structure (usually cylindrical or drum-shaped) that mounts the friction plates, steel plates, and piston.

Power Transmission Hub: The outer spline connects to the friction plates or steel plates, and the inner bore connects to the gearbox input shaft/planetary gear elements, transmitting power to the gearbox system.

Cooperative Operation of Friction Plates and Main Clutch Support

Power Engagement: The TCM issues a shift command → The valve body (including related solenoid valves/lubrication valves) outputs pressurized oil → The oil enters the piston chamber through the support's oil passages → The piston pushes the friction plates against the steel plates, pressing them together → The support transmits power to the gear system via splines.

Lubrication and Cooling: The oil flow regulated by the lubrication valve → passes through the support's oil passages → continuously flushing the friction plate surface to remove heat → simultaneously lubricating bearings, splines, and other components.

Power Disengagement: The valve body cuts off the oil pressure → The piston returns to its original position → The friction plates separate from the steel plates → The support stops transmitting power.
