Abstract

An actuator for a twin clutch device includes a single electric motor, first and second drive mechanisms, first and second transmission mechanisms, first and second hydraulic damper mechanisms and a control unit. Each first/second drive mechanism is configured to receive a first/second directional rotation from the electric motor and drive its respective first/second release member in a first operational direction. Each first/second transmission mechanism is configured to transmit only the first/second directional rotation from the electric motor to its respective first/second drive mechanism. Each first/second hydraulic damper mechanism is configured to regulate a moving speed of its respective first/second release member in a second operational direction opposite to the first operational direction. The control unit is configured to control the rotation of the electric motor.

Dependent claims

An actuator for a twin clutch device, the actuator being configured to operate a first release member and a second release member in the twin clutch device, the actuator comprising:

a single electric motor;
a first drive mechanism configured to receive a first directional rotation from the electric motor and drive the first release member in a first operational direction, the first drive mechanism including
a first rotary shaft;
and
a first drive member movable in the first operational direction and the second operational direction by means of a rotation of the first rotary shaft, the first drive member being configured to drive the first release member in the first operational direction;
a second drive mechanism configured to receive a second directional rotation from the electric motor and drive the second release member in the first operational direction, the second drive mechanism including
a second rotary shaft;
and
a second drive member movable in the first operational direction and the second operational direction by means of a rotation of the second rotary shaft, the second drive member being configured to drive the second release member in the first operational direction;
a first transmission mechanism configured to transmit only the first directional rotation of the electric motor to the first drive mechanism;
a second transmission mechanism configured to transmit only the second directional rotation of the electric motor to the second drive mechanism;
a first speed regulation mechanism configured to regulate a first moving speed of the first release member in a second operational direction opposite to the first operational direction;
a second speed regulation mechanism configured to regulate a second moving speed of the second release member in the second operational direction;
and
a control unit configured to control the rotation of the electric motor.
