Electronic Control Coupling

•
An electromagnetic clutch, which operates smoothly due to the lack of influence from the
front and rear wheel traction force, has been used for the electronic control coupling
system.
•
The construction of the coupling enables the torque formed by the pilot clutch to be
amplified by the cam mechanism, thus allowing the main clutch to obtain a high degree
of torque.
•
The electronic control coupling basically consists of an electromagnetic clutch, a cam
mechanism and a torque transmission system.
•
The electromagnetic clutch consists of a 4WD solenoid (electromagnetic coil), rear
housing that forms a magnetic path, pilot clutch, and armature. The cam mechanism
consists of a pilot cam, balls, and main cam. The torque transmission system consists of
a main clutch and ATF (Automatic Transmission Fluid).
