| 摘要 |
The present invention relates to a linear-conversion actuator (100) applying a linear driving force to a piston (17) of a semi-auto clutch driving device, comprising: a driving mater cylinder (18) with a clutch pedal (11), a master cylinder (14), the piston (17); a driving motor (110), a release cylinder (19), and a clutch disc (22). The present invention provides the linear-conversion actuator of the semi-auto clutch driving device including: the driving motor (110) with a rotary shaft (111) protruding from one side of the driving motor (110); a screw (120) with a coupling joining unit (121) connected to the rotary shaft (111) by a coupling (131) received in a coupling housing (130); a retractable rod (160) connected to the screw (120) and reciprocating and moving the piston (17) of the driving master cylinder (18) by being retractable while reciprocating forward and backward when the screw (120) rotates; and a body (170) receiving the screw (120) and the retractable rod (160) inside and guide grooves (171) on the inner upper and lower parts. The present invention enables remarkable improvement of durability and convenient maintenance by structurally simplifying the actuator. Especially, the present invention is capable of precisely controlling the actuator, thereby enabling stable conversion. |
