Abstract:
1. An actuating device for a transmission of a vehicle operative for moving a trip cam of the transmission forward and backward in a longitudinal direction, and also in a transverse direction in one direction or the other transversely to the longitudinal direction, the actuating device comprising a drive device with a spindle that includes two axially adjacent thread sections with opposing thread directions; a spindle nut provided on each of said thread sections of said spindle; a drive motor for each spindle nuts to drive a respective one of said spindle nuts in a rotary motion; and a coupling member engageable with the trip cam and moving the later in the longitudinal and transverse directions, said coupling member being actuatable using said spindle, wherein said spindle has an output side and is provided on said output side with a motion convertor which converts a rotary output motion of said spindle, in one direction of rotation or in the other, into a translatory transverse motion of said coupling member in one transverse direction or the other, wherein said motion convertor is carried in the longitudinal direction with said spindle, and a longitudinal motion of said spindle results in a corresponding longitudinal motion of said coupling member.
