CLUTCH DISC
OPERATING MECHANISM
The clutch cover assembly is fitted to the flywheel of
the engine by several bolts, and rotates integrally with the
same speed as the engine.
The diaphragm spring type exerts pressure against the pressure plate
more equally than the coil spring type.
The clutch disc may be worn to a greater extent without reducing the
pressure that is applied to the pressure plate.
Unlike the coil spring type clutch, whose spring force decreases at
high speed ranges because of centrifugal force, the diaphragm spring
type clutch is free from such a problems.
Since the diaphragm spring require only a small space in the axial
direction, cooling fins can be installed on the pressure plate.

The propeller shaft is a lightweight hollow carbon steel
tube which is strong enough to resist torsional- bending.
universal joint yokes are welded to both
ends of this tube.
The overhall length of each segment of the two joint type propeller shaft
is relatively great. This means that, when the propeller shaft rotating at
high speed, the shaft tends to bend sligtly and vibrate more because o
of the residual unbalance. So a higher precision balance is required
to minimize such deflection and vibration.
On the contrary, the length per shaft of the two piece, three-joint type
propeller shaft is shorter and bending due to imbalance is therefore
less. Vibration at high speeds is also reduced for the same reason.
The three-joint type propeller shaft used more often today because of
These advantages.
The purpose of the universal joint is to absorb the angular
changes brought about by changes in relative positions of
the differential in relation to the transmission, and in this
way to smoothly transmit power from the transmission to
differential.
The center bearing supports the two parts of the propeller shaft at
the middle, and is installed via flange to the splines located at the
end of the front propeller shaft (called an intermediate shaft). The
center bearing itself, consists of the rubber bushing that covers the
bearing which, in turn, support the propeller shaft, and is fitted to
the body through a bracket.
The drive shafts transmit the rotation of the engine to the wheels via
the transmission and differential. They are used on vehicles with drive
(2) Since the same wheels are used for steering and for
driving, they must be capable of maintaining the same
operating angle while the front wheels are being steered,
and they must rotate the wheels at uniform speeds.
The constant velocity joint is designed mush the same
as set of bevel
gears. Balls and grooves are used, rather than gears.
Ball and grooves connect the input and output shafts.
If the balls are placed in elongated grooves, the result
is a CV joint. This type of joint does not produce the
speed or velocity changes on the output shaft that a
cross and bearing type universal joint produces. As
you recall, when a cross and bearing universal joint is
used, there are several speed variations within each
revolution of the drive shaft.
As the tripod joint has three rollers and is simple in
designed, it costs less to manufacture. Normally, most
joints of this type are designed in such a way that they
can move in the axial direction.
This is a joint having several steel balls, which allows a
uniform speed to be maintained with a high very
accuracy.
The purpose of the differential is to transmit the torque from
The drive shaft to the axles and drive wheels of the vehicle.
On front wheel drive vehicles, the differential is located
Inside the transaxle is a part of the total assembly. Torque
Is transmitted from the engine, through the transmission
And to differential. The differential then splits the torque and
Sends it to the drive wheels.
