The BorgWarner Multi-Mode Clutch Module is a multi-mode rotation device. The flexible clutch design can provide up to four different modes and combinations. 1) Overrun Mode: freewheel in both rotation directions with very low drag 2) Lock Mode: transmits torque in both directions similar to a dog clutch or engaged friction clutch pack 3) One-way Clockwise Mode: clutch race freewheels in clockwise rotation direction and locks in opposite direction 4) One-way Counter Clockwise Mode: clutch race freewheels in counter clockwise rotation direction and locks in opposite direction How the Multi-Mode Clutch Module works: The Transmission Control Unit (TCU) selects the operating mode. The actuator indexes the cam plate to block or unblock the locking element or engagement notch. Technical Features and Advantages: Improved fuel economy, High torque capacity, Flexible engagement control, Better shift feel, Low system total mass, Low rotating mass, Optimal mode biasing plate flexibility, Engaging or disengaging locking elements, Simplified manufacturing (Bearing grade steel NOT required), Small cross-section required - axially and radially, High torque density, Can reduce total number of clutches in transmission.
