Multiplate clutch
Construction
Multi plate clutch has more than one clutch
plate known as metal plates and also it consist of number of outer plates
known as friction plates. Friction plates are slides and engage by means of
slots on the cover which is bolted to the flywheel. A pair of lining made of an
asbestos based material is riveted to the both the side of clutch plate and
clutch plate is sandwiched between two friction plates in multi plate clutch.
The inner splines of clutch plates are fitted on the splined hub. They also
slides on the splined hub. Trust spring push the plates together to form a
drive. The size of clutch plates is small as compared to single plate clutch.
Working
When
clutch is in engage position, clutch plates are gripped between friction plates
with the help of thrust spring also known as pressure spring. All the plates
pressed together causing to rotate at same speed The drive is transmitted
from flywheel to outer plates then outer plates or friction plates to clutch
plates and finally it transmitted to clutch shaft. As shown in fig. clutch is
in disengaging position, when pressure is applied on the friction plates with
help of push pedal. Clutch plates and friction plates gets separate from each
other so that clutch plates rotate separately due to inertia and then stops.
Thus clutch gets disengage so drive is not transmitted from friction plates to
clutch shaft.
