  • Patent number: 9181990
    Abstract: A clutch actuator for a vehicle includes a lifting member having a first end connected to a power generator, a middle portion provided with a hinge point, and a second end formed with an inclined plane, the lifting member being linearly moved by receiving a power from the power generator; a guide member provided at one side of the second end of the lifting member to rotate the second end of the lifting member around the hinge point as the lifting member is linearly moved while the inclined planes are supported; and a lever provided at one side of the lifting member and having a first end thereof supported by a clutch housing and a second end rotating around the first end by being pressed by the lifting member according to the movement/rotation of the lifting member, to engage with or release a clutch.

  • Patent number: 8821346
    Abstract: A clutch actuator unit is provided that includes a housing having a mounting space and a penetration aperture for receiving an operating rod. A slide pad and slider are disposed along an inner side surface of the mounting space, and are configured to move back and forth within the housing. An operating rod that is connected to the slider through the penetration aperture is moved back and forth, along with the slider and slide pad, through the aperture via a drive portion. A stopper is also integrally formed along the front surface of the slide pad to limit the movement of the slider accordingly. In doing so, the disclosed actuator is able to dynamically locate certain stroke positions and provide an improved shifting operation.
