In addition, some clutches for heavy-duty applications has a two friction plate and an intermediate pressure plate. Some clutches are operated by hydraulic means. The dry single-plate type of friction clutch is almost used in American passenger cars.The various types of clutches used in the automobile depend upon the type and use of friction.Most designs of the clutches use a number of coil springs but some use a diaphragm or conical type spring. The type of friction materials also varies in the clutches of different passenger cars.Types of ClutchesFollowing are the different types of clutches:Friction clutchSingle plate clutchMultiplate clutchWetDryCone clutchExternalInternalCentrifugal ClutchSemi-centrifugal clutchConical spring clutch or Diaphragm clutchTapered finger typeCrown spring typePositive clutchDog clutchSpline ClutchHydraulic clutchElectromagnetic clutchVacuum clutchOverrunning clutch or freewheel unitRead also: What is clutch and how it works?Single Plate ClutchSingle plate clutches are one of the most commonly used types of clutches used in most modern light vehicles. The clutch helps to transmit torque from the engine to the transmission input shaft. As the name states it has only one clutch plate.It consists of a clutch plate, friction plate, pressure plate, flywheel, bearings, clutch spring and nut-bolts arrangement.The single-plate clutch has only one plate which is attached on splines of the clutch plate. Single plate clutch is one of the main components of the clutch. The clutch plate is simply thin metallic disc which has both side friction surfaces.The flywheel is attached on the engine crankshaft and rotates with it. A pressure plate is bolted to flywheel through clutch spring, which provides the axial force to keep the clutch engaged position, and is free to slide on the clutch shaft when the clutch pedal is operated.A friction plate which is fixed between the flywheel and pressure plate. The friction lining is provided on both sides of the clutch plate.Working:In a vehicle, we operate the clutch by pressing the clutch to peddle for disengagement of gears. Then springs get compressed and the pressure plate moves backwards. Now the clutch plate becomes free between the pressure plate and flywheel. Due to this now the clutch is getting disengaged and able to shift the gear.

A friction clutch can be used by engineers in engaging and disengaging transmission and flywheel.

For engaging clutches, Centrifugal clutch uses the concept of centrifugal force. It is operated automatically according to the speed of an engine. Thus, in a vehicle, any clutch paddle is not required for the movement of the clutch.A driver can stop as well as can start an engine without downing or upping the gear. FOR REUSE ATTRIBUTION NEEDEDWorking Principle of Centrifugal Clutch:This clutch includes a weight that is pivoted in a specific location. According to engine speed centrifugal force moving up the weight and it applies force on the bell crank. Due to this, the plate is pressed.
For keeping in the engaged position, the semi-centrifugal clutch uses spring force along with the centrifugal force. Semi-Centrifugal Clutch is made of a Clutch plate, Friction lining, Levers, Pressure plate, Flywheel, and Clutch springs.Working Principle of Semi-Centrifugal Clutch:Clutch spring and levers fix upon the pressure plate equally. At a normal speed of an engine, the clutch is designed to send torque spring.At a normal speed and low power transmission, there is no pressure on the pressure plate. Hence, a clutch remains engaged.
Consumer inclination in countries such as China and India is towards affordable cars with AMT systems, this is resulting in growth of AT system in these countries. On the basis of clutch type, the automotive clutch market is segmented into dog clutch, friction clutch, centrifugal clutch, semi centrifugal clutch, hydraulic clutch, vacuum clutch and electro-magnetic clutch.
The NLSTM centrifugal clutch is a rugged time-provenunit which provides equipment protection and systemoverload protection. This is done by allowing the motoror other driving source to accelerate to operating speedwithout load and to slip automatically when overloaded.This clutch is available in a free (type A) and delayedengagement (type AD) model, also in various sizes tohandle different horsepower capacities. 2ff7e9595c
