In an automobile engine, there is a mechanical device that allows the engine to work at a stationary position It is called a clutch. The component engages and disengages power transmission especially from a driving shaft to the driven shaft. In order words, clutches connect and disconnect two rotating shafts (drive shafts or line shafts).

Today we’ll be looking at the definition, working principle, parts, types, functions, as well as problems of clutch systems in automobile engines.


What is a clutch?

A clutch is a mechanical device that engages and disengages the power transmission from the driving shaft to the driven shaft. The device features two-shaft, one is connected to the engine or power unit (the driving member) while the other shaft provides the power output that does the work.

Working principle of a clutch

The working principle of a clutch is quite interesting and easy to understand. It works perfectly fine in that no torque/power is transmitted until the friction plates touch each other. The clutch consists of two different plates, one is mounted to the flywheel, and the other moves over the crankshaft. The amount of torque applied determines the amount of axial load that is applied to the friction disc.

This is to say the more the axial load the more the power transmission and the less the axial load, the lesser the power transmission. The moveable disc which is splined on the crankshaft moves back and forth with the aid of the clutch pedal. The load is applied by the pressure plate which is connected to multiple helical springs or single diaphragm springs. If the clutch pedal is complete press, the moveable friction disc moves back from the shaft which disengaged from the flywheel.

As there is no axial load applied by the pressure plate hence there is no power/torque transmission applied. This is why the engine can run without moving. And if the clutch pedal is completely released, the moveable friction disc slides forward on the shaft to the flywheel. This is the engaged condition when the disc touches the flywheel. The amount of working pressure applied is also determined by how much the clutch pedal is pressed. This means the amount of axial load applied by the pressure plate will reflect on the power transmitted.
