4WD SYSTEM USING DRUM CLUTCH FOR FRONT WHEEL DRIVE-BASED VEHICLE

摘要

The present invention relates to a 4WD system and, more specifically, to a 4WD system, which can increase efficiency of power transfer by using a drum clutch, improve 4WD response performance by using a centrifugal force of a drive shaft; and improve fuel efficiency by completely blocking a driving force to be transferred in a two-wheel drive driving condition. According to the present invention, the 4WD system comprises: a drum clutch module; an actuator module; and a 4WD control module.;COPYRIGHT KIPO 2016
