Transfer case operation mode shifting apparatus for a four-wheel drive vehicle |
摘要 |
A transfer case operation mode shifting apparatus is actuated by an electric actuator including an electric motor and a differential power transmitting mechanism which transmits a driving power for axially moving a differential gear shift member to shift a center-differential gear assembly between a four-wheel and a two-wheel drive mode of operation. The driving power transmitted by the differential power transmitting mechanism and acting on the differential gear shift means is smaller when shifting the center-differential gear assembly from the four-wheel to the two-wheel drive mode of operation than when shifting back the center-differential gear assembly from the two-wheel to the four-wheel drive mode of operation. |
