HYDRAULIC CLUTCH SYSTEM

 REAL MAN USES THREE PEDAL 💪

THINGS TO KNOW ABOUT CLUTCH 


DEFINITION 👇

The hydraulic clutch is a type of automotive clutch that uses hydraulic fluid rather than a cable to move the clutch plate. These clutches have a master cylinder linked to the clutch pedal, which moves the fluid inside the clutch lining with high pressure when the driver presses the clutch pedal to disengage the clutch. 

CONSTRUCTION AND PARTS 🔧


1. Clutch pedal:
The clutch pedal is the primary part that engages a clutch in a vehicle. The clutch disengagement process starts when a driver presses the clutch pedal.
 
2. Master Cylinder:
As the name suggests, it is a primary hydraulic cylinder in which the clutch fluid is applied at high pressure with the help of a piston present inside the cylinder.
 
The clutch fluid reservoir is connected to the master cylinder which supplies the clutch fluid when the clutch pedal is pressed.
 
3. Pressure Pipe:
It supplies the fluid from the master cylinder to the slave cylinder at high pressure to operate the clutch.
 
4. Slave Cylinder:
The slave cylinder is the second hydraulic cylinder present in the system. It consists of a push piston rod that is connected to the clutch release fork.

The fluid from the master cylinder enters the slave cylinder and presses against the push piston rod which in turn actuates the release fork.
 
5. Release fork:
The clutch release fork is connected to the slave cylinder at one end and another end is connected to the clutch shaft which has the clutch release bearing mounted on it.
 
When the clutch pedal is pressed, it is used to press the release bearing on the diaphragm to apply pressure on it.
 
6. Release bearing:
The clutch release bearing is mounted on the clutch shaft. It presses against the middle of the diaphragm spring when the clutch pedal is pressed.
 
7. Diaphragm spring:
The diaphragm is a semi-circular or ‘C’ shaped spring. It is mounted on the pressure plate and is used to maintain pressure on the clutch plate.
When the clutch pedal is pressed, the middle of the diaphragm spring is pushed in and the spring pulls the pressure plate away from the clutch plate.
 
8. Pressure plate:
The purpose of the pressure plate is to push the friction plate against the flywheel. It is kept under pressure with the help of the diaphragm spring.
 
When the clutch pedal is pressed, the diaphragm spring pulls away from the pressure plate clutch plate, which causes disengagement of the engine from the transmission.
 
9. Splined sleeves:
The splined sleeves are located between the friction lining of the clutch plate and the pressure plate. The pressure plate keeps the splined sleeves under pressure to keep the clutch engaged.
 
When the pressure plate releases pressure the splined sleeves to pull away and it disengages the engine from the transmission.

10. Clutch plate:
The clutch plate is held between the pressure plate and the flywheel. It has friction lining on both sides of its surface. The frictional surface creates friction between the flywheel and the pressure plate.

The friction between them is responsible for producing or interrupting the power flow between the engine and transmission.

11. Flywheel:
The flywheel is a part that is connected to the engine crankshaft at one end and the clutch plate at the other end. The flywheel is responsible for transferring the flow of power from the engine to the transmission through the clutch plate.

When the clutch pedal is pressed, the linkage between the flywheel and clutch plate is interrupted. This causes disengagement of the power transfer and permits the change of gears smoothly.


WORKING PRINCIPLE 

The basic function of a clutch is to produce the flow of power from the engine to transmission and interrupt the flow of power to enable the change of gears without slippage. This is done by separating the linkage between the flywheel and the pressure plate.

The Hydraulic Clutch utilizes the fluid stored in the reservoir when the clutch pedal is pressed. The pushing force on the clutch pedal will force the piston inside the master cylinder and the fluid will be compressed to high pressure. 

Pressure pipes are used to transfer the high-pressure fluid from the master cylinder to the slave cylinder.

BRAKE SYSTEM

  THE BRAKE SYSTEM What is a brake system ?       A brake is a mechanical device designed to restrain motion by absorbing energy from a moving system usually by the means of friction. It is used to slow or stop a moving vehicle, wheels, axle, etc. The braking system is a complication device with a lot of parts, but its working seems very easy. After all, pressing a single pedal will activate all brakes on the four wheels. The slowing down is achieved by hydraulic fluid, which is often bleed to get the best performance of the breaking. Air is not allowed in the system else the component won’t work well.      Most brakes are designed to use friction between two surfaces, they’re pressed to convert the kinetic energy of the moving object into heat. Though several methods of energy conversion are now employed. In an automobile, friction brakes store braking heat in the drum brake or disc brake which then gradually converts into the air.  ...

4G63T ENGINE

THE GLORY MITSUBISHI’S 4G63 ENGINE: SPECS, POWER & RELIABILITY Popularly dubbed as the 2JZ of the 4-cylinder world, the 4G63 is a real hoot to have under the hood. The fact that it was built to meet the standards of the World Rally Championships explains why it can be tuned to make over 1000 hp. History of Mitsubishi’s 4G63 Engine The 4G63 engine was first introduced in the 1980 Mitsubishi Galant model as a replacement for the 4G52 engine. It’s part of the Mitsubishi Sirius 4G6 engine family; a series of inline-four high-performance engines that were produced by Mitsubishi in the late 70s. In fact, when Mitsubishi sought to compete in the FIA World Rally Championship, it introduced the turbocharged version of the 4G63 engine in the Galant VR-4, Lancer Evolution, Lancer EX 2000 Turbo, and Carisma GT. At the peak of its glory, the Mitsubishi Lancer Evolution III fitted with a turbocharged 4G63 engine dominated the World Rally Championship by winning four consecutive titles. 4G63 En...

MOTOR OIL (ENGINE OIL)

  A guide for you to know about motor oil.  In this blog you will get to know what is the motor oil does means to you. Here’s what we’ll cover: What is motor oil? What is in motor oil? What must a motor oil do? What is viscosity? SAE viscosity grades (oil weights) What is motor oil?  Motor oil is one of the most important factors in your engine’s performance and longevity. Put simply,  it’s the lubricant that prevents all those metal parts from tearing each other apart or welding themselves together  into the world’s coolest boat anchor. It reduces friction and heat while helping keep your engine clean. Without motor oil, your engine would destroy itself in a matter of seconds. What is in motor oil? Motor oil contains two fundamental components:  base oils  and  additives . The two work in tandem to produce the final product you put in your engine. Think of coffee as an analogy – the base oil is the water and the additive package are the co...
