GEAR ACTUATOR OF DUAL CLUTCH TRANSMISSION

摘要

The present invention provides a gear actuator of a dual clutch transmission, which is used to operate a dual clutch transmission. The gear actuator of a dual clutch transmission comprises a shift device part and a select device part. The shift device part comprises: a screw member rotated by a shift motor; and a movement member moved in the longitudinal direction of the screw member by rotation of the screw member. The select device part comprises: a driving gear rotated by a select motor; a driven gear engaged with the driving gear to be rotated; a first one-way clutch bearing coupled to one end of the driven gear; a first finger coupled to the first one-way clutch bearing and having a first protrusion formed from a rotation center in a radial direction; a second one-way clutch bearing coupled to the other end of the driven gear to be rotated in a direction opposite to the first one- way clutch bearing; a second finger coupled to the second one-way clutch bearing and having a second protrusion formed from a rotation center in a radial direction; and a shift member coupled to the movement member to be moved in an axial direction together with the first finger and the second finger and performing relative rotation with the first finger and the second finger.
