Abstract
An electric gearshift mechanism for a change-speed gearbox of a motor vehicle with selector gates has an electric motor and a gear shifting member. The gear shifting member can be moved in two substantially mutually transverse shifting movements. The gear shifting member includes a threaded spindle having an axis of rotation drivably connected to the motor carrying a nut having a finger for preselecting selector gates. A linear guide conducts the nut along the axis and a clutch rotatably connects the nut and the spindle.

An electric gearshift mechanism for a change-speed gearbox with selector gates for a motor vehicle comprising:
- an electric motor;
- and
- a gear shifting member for providing two substantially mutually transverse shifting movements, said member including a threaded spindle having an axis of rotation drivably connected to said motor;
- a nut carried by said spindle having a finger for preselecting selector gates;
- linear guide means for guiding said nut along said axis;
- and, clutch means for connecting said nut and said spindle to rotate together so as to rotate the finger.
An electric gearshift mechanism for a change-speed gearbox with selector gates for a motor vehicle comprising:
- an electric motor;
- and
- a gear shifting member that can be moved in two necessary and substantially mutually transverse shifting movements, said gear shifting member including a threaded spindle having an axis of rotation drivably connected to said electric motor, a nut carried by said threaded spindle having a finger for preselecting selector gates, linear guide means for guiding said nut axially and holding said nut fast against rotation to derive a linear movement, and clutch means for releasably and non-rotatably connecting said motor and said guide means to derive a rotary movement of the finger.
