End Of SieELECTRONIC CONTROL COUPLINGA6E632227100202Outline
Features
•An electromagnetic clutch, which operates smoothly due to the lack influence from the front and rear wheel
traction force, has been adopted 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. Due to this, size and weight
reduction of the component parts has been achieved.
Construction
•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 hydraulic oil (ATF).
