Switchable reduction gear and lockable differential gear actuating device for all-terrain vehicle, has coupling device including actuating element pivoted within operating condition areas and attached to switching element of reduction gear

摘要

The device (1) has an electrical machine (4), and a coupling device (7) converting rotary drive of the electrical machine into operating movement of a switching element (5) of a switchable reduction gear (2) for adjusting transformation of the reduction gear and a switching element (6) of a lockable differential gear (3). The coupling device comprises an actuating element (23) pivoted within operating condition area and another operating condition area over a nut (17) of a spindle-nut-arrangement (14) and attached to the switching element of the reduction gear.
