How Many Types of car Clutchs?

A clutch is a mechanical device that plays a crucial role in power transmission by enabling the engagement and disengagement of rotational motion between a driving and driven shaft.

It is an essential component in transmission systems, particularly when changing gears. When the clutch is engaged, power flows from the engine to the wheels through the transmission system, propelling the vehicle forward.

1. Positive and Spline Clutch:

In a positive clutch system, grooves are carved into either the driving member or the driven member, with specially designed components in both members. When the driver releases the clutch pedal, these specialized parts engage with the grooves, causing the driving and driven shafts to rotate together.

2. Friction Clutch:

The friction clutch is a highly significant type of clutch used for transferring rotary motion from one shaft to another as needed. In this type of clutch, the axes of the two shafts align perfectly.

3. Single Plate Clutch:

A single plate clutch consists of a clutch plate attached to a hub with splines, allowing it to slide axially along the splines of the driven shaft. The clutch plate is typically made of steel and features friction linings on each side, known for their high coefficient of friction. The engine shaft supports a flywheel.

4. Multi-plate Clutch:

In a multi-plate clutch, the capacity to transmit torque is increased by incorporating a higher number of frictional linings and metal plates. The friction rings feature splines on their outer periphery, allowing them to engage with corresponding splines on the flywheel.

5. Cone Clutch:

Cone clutches feature contact surfaces shaped like cones. In the engaged position, the friction surfaces of the two cones are in complete contact due to spring pressure, ensuring continuous contact while the clutch is engaged.

6. Centrifugal Clutch:

Centrifugal clutches are increasingly utilized in automobiles and machines. They consist of a driving member with four slipping blocks that are held in position by flat springs.

7. Hydraulic Clutch:

This type of clutch utilizes hydraulic fluid to transmit torque. Based on their design, this clutch is divided into two types: Fluid Coupling and Hydraulic Torque Converter.

8. Electromagnetic Clutch:

The electromagnetic clutch utilizes electromagnetism to apply pressure and engage the clutch. In this type of clutch, the driving plate is connected to electric coils.

9. Hysteresis-powered Clutch:

Electrical hysteresis units offer an exceptionally wide torque range, making them highly suitable for testing applications that require variable torque. These units can be precisely controlled, allowing for precise adjustment of torque levels.

10. Semi-centrifugal Clutch:

In this type of clutch, power transmission is accomplished through a combination of clutch springs and the centrifugal action of an additional weight integrated into the system. This configuration allows for efficient engagement and disengagement of the clutch, particularly in demanding scenarios such as racing or high-performance driving.

11. Diaphragm Clutch:

In a diaphragm clutch, coil or helical springs are replaced with diaphragm springs. Unlike other types of clutches, diaphragm clutches do not require separate release levers, as the diaphragm spring itself serves as a series of levers.

12. Vacuum Clutch:

A vacuum clutch linkage operates through the vacuum created during the engine's suction stroke. It comprises a vacuum reservoir tank connected to the engine's inlet manifold via a non-return valve.

13. Freewheel Clutch:

A Freewheel clutch is a mechanical device that allows rotational motion in one direction while preventing it in the opposite direction. It consists of two members: the inner race and the outer race.
