Clutch actuator cuts weight, cost

What: Centrifugal electrohydraulic actuator for all-wheel drive
Innovation: The device uses an electric motor drive pump and a centrifugal pressure regulator to control the hydraulic pressure to an all-wheel-drive clutch. By eliminating a standard system’s accumulator, electronic solenoid control valve and pressure sensor, the actuator is less complex and more compact. The result: a less expensive actuator that is 20 percent lighter.
