Abstract
An actuator used for an automatic cruising control device and possible to be assembled very easily, which comprises an electric motor, reduction gear, an electromagnetic clutch provided with a clutch yoke and a bobbin formed with a coil, an output pulley to be connected to a throttle valve of the engine of the motor vehicle through a throttle cable, and the clutch yoke and the bobbin are provided with coupling means composed of, for example, a hook formed to the bobbin, a hook-insertion hole formed in the clutch yoke and a hook-engaging part formed in the vicinity of the hook-insertion hole of the clutch yoke. The bobbin is easily fastened to the clutch yoke through the coupling means by snap action.
Claims10
An actuator comprising:
- an electric motor;
- reduction gears connected with a motor shaft of said electric motor;
- an electromagnetic clutch combined with a final section of said reduction gears;
- and
- an output pulley combined with load and an output section of said electromagnetic clutch, wherein
- said electromagnetic clutch is provided with a clutch yoke for forming a magnetic circuit and a bobbin housed in said clutch yoke, and said clutch yoke and said bobbin are formed with coupling means for fastening the bobbin to the clutch yoke by snap action.
An actuator comprising:
- a case;
- an electric motor housed in said case;
- reduction gears housed in said case and connected with a motor shaft of said electric motor;
- an output shaft maintained in said case;
- a rotor combined with a final section of said reduction gears and supported rotatably by said output shaft;
- a clutch yoke secured to said case;
- a bobbin housed in said clutch yoke;
- a coil formed around said bobbin;
- a clutch disk rotatably supported by said output shaft to be attracted to said rotor according to excitation of said coil;
- an output pulley rotatably supported by said output shaft and combined with load;
- and
- a clutch spring disposed around said output shaft and engaged between said clutch disk and said output pulley for transmitting rotational force of the rotor to the output pulley according as the clutch disk is attracted to the rotor by the excitation of the coil;
- said clutch yoke and bobbin being formed with coupling means for fastening the bobbin to the clutch yoke by snap action.
