Schaltvorrichtung für mehrstufige Schaltgetriebe

摘要

A shift mechanism for shifting multi-ratio gearboxes of motor vehicles is connected to an electric motor which can be connected via a coupling mechanism and a clutch to a shift rod (9) displaceable essentially parallel to the axis of the gears. Depending on the clutch position, the coupling mechanism provides either a rotary connection with the electric motor or conversion of the rotary motion of the electric motor into a translational motion of the shift rod (9). To connect the shift rod (9) to the electric motor is a spindle mechanism. The spindle nut (1) of the spindle mechanism is firmly connected to the rotor (6) of the electric motor or represents part of the rotor (6), and the clutch (13, 23) is arranged between the rotor (6) and the spindle (2) or a part connected firmly in terms of rotation to the spindle, and the coupling mechanism (18) is arranged between the shift rod 9 and the housing (19).
