Clutch Shoes

Clutch shoes are made from composite material or aluminum. They are attached to the engine flywheel. They expand under increasing RPM to activate the clutch bell which in turn employs the spur gear for moving the vehicle.

Types of Clutch Shoes

• Aggressive Clutch Shoes: The friction force acts in a direction to increase the normal force with the contact surface. This increases the torque, but reduces operating smoothness.
• Non Aggressive Shoes: Non aggressive clutch shoes operate more smoothly, but with lower torque transfer.

Characteristics of Clutch Shoes
