Clutch Use and Function Toyota L Engine Guide

Clutch Use and Function

This is a clutch disk of Toyota L engine. It is not noticeable that this has already a defect upon driving but since the engine was overhauled and is obviously thin it should be replaced to minimize time and work.

2. The Function of the Clutch

The clutch is located between the engine and transmission. The clutch engages the engine with the transmission to move the vehicle. In the same way, the clutch disengages the engine from the transmission by pressing it and changing gears to neutral thereby you can you can halt your vehicle through the break.

A detailed explanation of how the clutch works are viewed here:

 

3. Types of Clutch (Hino)

Single Plate Type-This refers to clutches that use a single clutch disc between the flywheel and pressure plate. These types of clutches have simple construction, are lightweight, do not require large movements of the pressure plate, offer a good clutch response, and allow quicker gear shifting. The majority of Hino manual transmission vehicles currently use this type of clutch.

Dual Plate Type-This refers to clutches that use two clutch discs between the flywheel and pressure plate. These types of clutches are able to transmit greater torques and have smaller disc circumferences and consequently smaller inertial moments, which means they require less shifting force and pedaling force. These types of clutches are currently not used on many Hino vehicles.

4. Clutch Disk Materials

Molded disc-This type of disc produces less shock when the clutch engages. This means that this type has relatively fewer adverse effects on the drive train, and there is no need to replace the clutch cover or flywheel when replacing the disc.

This type of disc enables a greater half-clutching range, making it easier to operate the vehicle with the clutch not fully engaged. The outer edge of the disc is lightweight, producing less inertial moment and improves clutch response at high engine revolutions.

Metal disc-Metal material is durable and therefore offers a longer life cycle. Metal material offers good temperature characteristics with greater resistance to fading, which means that there are fewer adverse effects on performance caused by high temperatures, and less slippage even when the clutch is used extensively in the half-clutch state.
