3-4REAR AXLE - Axle Shaft / Drive Shaft
AXLE SHAFT
R03cAAAThe axle shaft is a semi-floating type supported by
ball bearings (outer and inner) in the housing.To prevent mud that may be deposited around the
bearing (outer), a dust cover has been provided.
D.O.J.
Companion flangeIG ?ust cover
Trailing arm
IllA0013
DRIVE SHAFTBirfield type constant velocity ball joints have been
provided for the drive shaft.
On the axle shaft side, the D.O.J. type has been
adopted to absorb the change in distance between
the joints that may be caused by the movement of
the suspension.
On the differential carrier side, the B.J. type has
been adopted which allows considerable flection in
keeping with the movement of the suspension.
Drive shaft and B.J.RO3OAAAOn the axle shaft side, they are coupled with the
axle shaft with the companion flange in between.
On the differential side, they are spline coupled with
the side gears.
On vehicles with a viscous coupling type limited slip
differential, the right and left drive shafts are
different in length. In addition, the B.J. side of the
drive shaft (R.H.) is two-stage serration coupled.

(3.7)The propeller shaft length is the length between the centers of the joints.
LOBRO JOINTRl6CMAThe
L6bro joint absorbs longitudinal displacement
and angle change and prevents the transmission of
vibration. It has the following features.
0Its constant velocity performance is excellent,
due to the inclination of the ball grooves of the
inner and outer races at same degree in
oppo-site directions.l It has a smaller sliding resistance in the axial
direction than a spline type slip joint.
l
It has smaller rotational variations, and hence is
more suitable for high speed operation than
other constant velocity joints due to smaller ball
play achieved by crossing the ball grooves of the
inner and outer races.

Since the rear clutch and the kickdown brake are actuated when theshift is in
2nd gear in the “0” or the “2” range, driving force is
transmitted to the forward sun gear which rotates in the clockwise
direction,
Therefore, torque is conveyed from the forward sun gear through the
short and long pinions to the annulus gear, as in the case of 1 st gear.
--However, since the reverse sun gear is fastened by in the case of
2ndgear, the long pinion“walks” on the reverse sun gear in the direction
of arrow (A), causing the annulus gear to rotate faster (or more) than
in the case of 1 st
gear in proportion to the length that the long pinionhas “walked”.
The reduction ratio of
2nd gear is achieved in this way.

Seat Belt Warning Light/Reminder Light

Outer Switch (LH., R.H.)
Located at the quarter panel on the driver’s seat side.The system is controlled based upon various input signals, thereby
regulating motor operation,
warnrng light illumination or continuousflashing, and buzzer sounding.
Located at the front of the guide railThis switch is for turning the shoulder belt drive motor off.
It transmits an “OFF” signal to the control unit when the shoulder
belt is completely unfastened. Once the “OFF” signal is received,
the control unit shuts off the motor.
Located at the rear of the guide railThis switch is for turning the shoulder belt drive motor off.
It transmits an “OFF” signal to the control unit when the shoulder
belt is completely fastened. Once the “OFF” signal is received,
the control unit shuts off the motor.
Located at the combination meter.
This light warns the driver
and/or passenger to fasten his/her seat
belt; it illuminates of flashes by the control unit, and the length of the
illumination or flashing time changes, dependent on which seat belt
is not fastened. (Refer to WARNING SYSTEM)
Located at the driver’s seat belt buckle.This switch transmits an “OFF” signal to the
control unit when the
lap belt is fastened and an “ON” signal when it is not fastened.
Incorporated within the shoulder belt retractor.
This switch detects the amount of shoulder belt wind-in and sends
an “OFF” signal to the control unit if the amount of wind-in is the
specified amount or more. or an “ON” signal if the amount of
wind-in is less than the specified amount.
