Abrasion compensation device, clutch actuator unit including abrasion compensation device, and vehicle including clutch actuator unit

An abrasion compensation device, comprising:

• an outer member including a groove of which the rear is opened and includes a female screw portion formed on an inner circumference surface of the groove;
• a push rod connected to a front of the outer member and pushing a first side of the fork;
• an inner member including a male screw portion screwed into the female screw portion formed on an outer circumference surface of the inner member, changing length thereof inserted in the groove by rotating around a central axis of the outer member, including a rotation center portion of a rear end portion thereof in which a support portion is formed and including a first gear portion formed at an outer side of the support portion;
• a fixed guide member guiding the outer member so that the outer member is not rotated and is not moved in front and rear directions, and including a reference pin formed at a front thereof which is a position corresponding to a position of the support portion;
• a pushing member including a second gear portion meshed with the first gear portion and pushing the inner member forward in a state where the second gear portion and the first gear portion are joined;
• an actuator using an actuator rod to push the pushing member forward or to pull the pushing member rearwards;
• and
• a controller controlling the actuator.

A vehicle comprising:

• a clutch actuator unit including an abrasion compensation device and removing an adhesive force between a clutch disc and a flywheel by using a diaphragm spring to press the clutch disc against the flywheel and by using a fork to push a first side of the diaphragm spring;
• and
• an engine that delivers torque to the flywheel,
• wherein the clutch actuator unit comprises:
• an outer member including a groove of which a rear thereof is opened and includes a female screw portion formed on an inner circumference surface of the groove;
• a push rod connected to the front of the outer member and pushing a first side of the fork;
• an inner member including a male screw portion screwed into the female screw portion formed on an outer circumference surface of the inner member, changing length thereof inserted in the groove by rotating around a central axis of the outer member, including a rotation center portion of a rear end portion thereof in which a support portion is formed, and including a first gear portion formed at an outer side of the support portion;
• a fixed guide member guiding the outer member so that the outer member is not rotated and is not moved in front and rear directions and including a reference pin formed at a front thereof which is a position corresponding to a position of the support portion;
• a pushing member including a second gear portion meshed with the first gear portion and pushing the inner member forward in a state where the second gear portion and the first gear portion are joined;
• an actuator employing an actuator rod to push the pushing member forward or to pull the pushing member rearwards;
• and
• a controller controlling the actuator.
