Clutch

Mechanical and Hydraulic Clutches

Two main types of clutches used in cars:
1. Mechanical (cable) clutch:

How it works: When the driver presses the clutch pedal, a steel cable is pulled, causing the clutch to disengage.
Components:
Clutch pedal: Directly controlled by the driver.
Steel cable: Transmits force from the pedal to the release bearing.
Release bearing: Squeezes the clutch diaphragm, separating the driven and driving parts.

2. Hydraulic clutch:

How it works: When the clutch pedal is pressed, a piston in the master cylinder creates pressure in the hydraulic system, which is transmitted to the slave cylinder, causing the clutch to disengage.
Components:
Clutch pedal: Controls the master cylinder.
Master cylinder: Converts mechanical force into hydraulic force.
Hydraulic fluid: Transmits pressure from the master to the slave cylinder.
Slave cylinder: Acts directly on the release bearing.
Release bearing: Performs the same function as in a mechanical clutch.

Advantages and disadvantages:

Mechanical clutch:
Advantages: Simple design, easy to repair.
Disadvantages: Can stretch over time, causing clutch slippage.
Hydraulic clutch:
Advantages: Softer engagement, smoother steering.
Disadvantages: More complex design, hydraulic fluid leaks are possible.

Modern cars are usually equipped with a hydraulic clutch due to its advantages.
