Application Of Single Plate Clutch

Here you can get application of single plate clutch. Single plate clutch used in different types of vehicles.

Single plate clutch is the most common type of clutch plate used in automobiles. It consists only one clutch plate which is mounted on the splines of the clutch plate. The Flywheel is mounted on the engine crankshaft and rotates with it.

Single Plate Clutch Application

  • Single plate clutches are used in trucks, buses, and cars etc.
  • Single plate clutches used where large radial space is available.
  • As sufficient surface area is available for the heat dissipation in Single plate clutches, no cooling oil is required. Therefore, single plate clutches are dry type.
  • In the automotive industry, a single plate clutch may be used via way of means of maximum of the cars across the globe. Due to the big radial form of the single-plate clutch, it’s far ordinarily utilized in big cars in comparison to small ones, together with buses, cars, vans specifically use a single plate clutch.
  • This sort of clutch does now no longer require any lubricant for cooling. But, in the back of this, some other purpose is present. Due to the big length of a single plate grab quantity of warmth dissipation takes place significantly. Therefore, oil or lubricant isn’t always had to cool the, plate.
  • Due to the high coefficient of friction, most of the vehicles use a single plate clutch. The amount of the coefficient of friction is more than 0.3. 
  • Apart from that, the amount of torque generation is also very high as compared to a wet clutch due to which this type of clutch can mostly be used in a big vehicle.
  • But, in regards to the application of a single plate clutch, the user has to prevent the contamination. Also, the moisture that presents within the plate should be prevented by the user through sealing the ports. 

Working Principle

The pressure plate is bolted to the flywheel through clutch springs and is free to slide (Move) on the clutch shaft when the clutch pedal is operated (Engage and Disengage).

If Clutch Engaged

When the clutch is engaged (Means when you not pressed clutch pedal), the clutch plate is gripped between the flywheel and pressure plate.

The friction linings are on both the sides of the clutch plate. The clutch plate revolves the flywheel because of the friction between the flywheel, clutch plate and the pressure plate.

The clutch shaft also revolves with clutch plate. Clutch shaft is connected to the transmission gearbox. Now, the engine power is transmitted to the crankshaft and then to the clutch shaft and gearbox.

Clutch always engaged due to the spring forces.

If Clutch Disengaged

When the clutch is disengaged (Means when you pressed clutch pedal), the pressure plate moves back against the force of the springs, and the clutch plate becomes free between the flywheel and the pressure plate.

The Flywheel always rotating with crankshaft. Then, Clutch shaft speed reduces slowly and stops rotating.

Line Diagram

This is the line diagram (Drawing) of Single Plate Clutch.

Line Diagram of Single Plate Clutch


  • Single Plate Clutch is not expensive.
  • It has little maintenance.
  • Gear shifting is easier compare to cone clutch because pedal movement is less.
  • Single Plate Clutch is more reliable because it does’t suffer from disadvantages of binding of cone.


  • Greater force required to disengage because the springs have to be more stiff.
