Drive mode
selector

The drive mode selector has been installed on the floor console.
When the dial is rotated with the ignition switch turned to ON
position, you can select the drive mode from FWD (2WD), AWD
(4WD), or LOCK modes.

ELECTRONIC CONTROL COUPLING

M22700000007USA0000010000

FEATURES

The  electronic  control  coupling  realizes  the  highly
reliable AWD system with lighter weight and simpler
construction.

The  electronic  control  coupling  is  comprised  of  the
front housing, main clutch, main cam, ball, pilot cam,

armature, pilot clutch, rear housing, magnetic coil, and
shaft.

｠

The front housing is joined to the propeller shaft and
rotates along with the shaft.

｠

The main clutch and pilot clutch are assembled to
the front housing on the outer side and to the shaft

on the inner side (The pilot clutch is installed via the
pilot cam).

｠

The shaft is engaged via serrations with the drive
pinion of the rear differential.

The drive force from the transfer is transmitted to the
front  housing  connected  to  the  propeller  shaft.  The
drive force is also transferred to the pilot clutch and
the  outer  side  of  the  main  clutch  assembled  to  the

front housing. Because the pilot clutch and the main
clutch  are  not  engaged  with  the  magnetic  coil  de-
energized,  the  drive  force  is  not  transferred  to  the
shaft and the drive pinion of the rear differential.

The drive force from the transfer is transmitted to
the front housing connected to the propeller shaft.
The drive force is also transferred to the pilot clutch
and the outer side of the main clutch assembled to
the  front  housing.  When  the  magnetic  coil  is
energized, the magnetic field is generated among
the  rear  housing,  pilot  clutch,  and  armature.  The
magnetic field induces the pilot clutch and armature
to engage the pilot clutch. When the pilot clutch is
engaged, the drive force is transferred to the pilot
cam.  When  there  is  a  difference  in  wheel  angle
between  the  front  and  rear  wheels  (i.e.  rotation
speed of the propeller shaft is different from that of
the drive pinion), the rotation speed of the pilot cam
applied with the drive force and that of the main cam
not  applied  with  the  drive  force  become  different.

The ball slides along the curved space between the
pilot  cam  and  main  cam  by  the  rotational  speed
difference and pushes the pilot cam and main cam.
Then, the main clutch is pushed toward the main
cam to engage. When the main clutch is engaged,
the drive force is transferred to the rear wheels via
the shaft and the drive pinion of the rear differential.

｠

By controlling the current applied to the magnetic
coil, the amount of the drive force transferred to the
rear wheels can be controlled within the range of 0
to 100%.
