Abstract
Disclosed herein is a dual clutch actuator including: a housing; a stroke controller disposed in the housing, and configured to actuate a clutch by linearly moving a pushrod; a power generation unit configured to generate driving power to operate the stroke controller; and a stroke return unit disposed between the housing and the stroke controller so as to elastically support the stroke controller, and configured to return the linearly moved pushrod to the original position, when the operation of the clutch is released. According to this structure, the dual clutch actuator can return the pushrod to the original position without an operation of a separate actuator, when removing a clutch connection.
Claims5
A dual clutch actuator comprising:
- a housing;
- a stroke controller disposed in the housing, and configured to actuate a clutch by linearly moving a pushrod;
- a power generation unit configured to generate driving power to operate the stroke controller;
- and
- a stroke return unit disposed between the housing and the stroke controller so as to elastically support the stroke controller, and configured to return the linearly moved pushrod to the original position, when the operation of the clutch is released;
- wherein the stroke controller comprises:
- the pushrod inserted into a through-hole formed in the housing and linearly moved;
- a driven gear rotatably fastened to the housing, and engaged with the power generation unit;
- a pushrod coupling part inserted on the driven gear, rotatably fastened to the pushrod, and linearly moving the pushrod in response to rotation of the driven gear;
- a pushrod holder disposed along the circumference of the pushrod;
- and
- a holder support extended from the pushrod holder, inserted into a guide hole of the pushrod coupling part, and preventing swaying of the pushrod when the pushrod is linearly moved.
