Abstract
A gearshift actuator configured to be driven by an eccentric electric motor has a rotating nut configured to be driven by the electric motor, an actuation member, and a converter adapted to convert a torque of the rotating nut into a translational force and to provide the translational force as an actuating force for a gear shift.
Claims10
A gearshift actuator configured to be driven by an eccentric electric motor, comprising:
- a rotating nut configured to be driven by said electric motor;
- an actuation member;
- a converter adapted to convert a torque of said rotating nut into a translational force and to provide said translational force as an actuating force for a gear shift;
- a first gear wheel;
- a second gear wheel;
- a rotary shaft, wherein a rotation axis of the rotating nut is the same as a rotation axis of the rotary shaft;
- and
- a sliding sleeve, configured, upon a translational movement, to couple the first gear wheel or the second gear wheel with the rotary shaft, said sliding sleeve being rotatable relative to said actuation member but axially fixed with respect to said actuation member to enable said gear shift driven by said electric motor,
- wherein the coupling is provided by a toothed internal surface of the sliding sleeve, facing the rotary shaft, and by toothed external surfaces on the rotary shaft, on the first gear wheel, and on the second gear wheel, respectively.
