Do you look for faster pick-ups and high velocity in cars that you drive? Then your car must have a multi-clutch system in the car.

Sports cars and sports bikes have these multi-clutch systems. These are used in place of single plate clutches. This system is not just for enhanced comfort for the drivers but also it makes cars safer. With advanced car technologies lower friction in power transmission is a need. Multi-clutch systems in cars are an essential feature of the present time.

Significance of Multi-Clutch Systems in Cars

Multiple friction plates stacked together in a multi-plate clutch system transmits high torque from engine to transmission. The features of multi-plate clutches are as follows:

• In a multi-plate clutch system, increase in the surface area of friction, leads to smoother engagements, improved heat dissipation and higher torque capacity compared to single plate clutch systems.
• Multi-plate clutch systems often use an oil-cooled ‘wet’ design for improving durability.
• It is light weight and compact in comparison to the single plate clutch system. Because of multiple plates distributing the wear among all of them in an even fashion, the total wear is much reduced on each plate. For this reason the engine system’s lifespan increases. As an impact, the longevity of the car that has a multi-plate clutch system increases a lot.
• Even though this system takes more plates, the part is quite lightweight and compact compared to the single plate clutch system. This system helps increase performance without slippage.

In modern small and light cars with high velocity, the multi-clutch system is more suitable compared to single plate clutch systems.

Checking for Multi-Clutch Plate in Used Cars

You can check the used car that you are buying to compare with the paper reports on it. It will be far better if you let a trusted mechanic/ technician check the parts of the car and then compare the reports. They can help you check if the car’s multi plate clutch is working or not in the car that you are about to buy.

• Where to find a multi clutch plate? - To check for a multi plate clutch in a used car you must look for a part mounted between the flywheel and pressure plate.
• How does a Multi-Clutch Plate look? - The part comprises many disc-like friction plates separated by steel separator plates.
• Checking if a multi plate clutch is working or not? - To check for a multi plate clutch working or not you need to check the followings: Whether a hydraulic mechanism or diaphragm spring presses the plates together to engage the transmission. Whether the gear box loses power flow once the clutch pedal is pressed as they remove pressure and allows the plates in the clutch system to separate.
• Multi plate clutch used in which vehicle? - This multi plate clutch is most common in sports cars. They are also found in dual-clutch transmission (DCT) cars where one clutch works on odd gears and the other on even gears. The presence of this part is obvious in AWD/4WD systems working for automatic all-wheel-drive systems that need dynamic torque distribution. Also, almost all motorbikes use wet multi-plate clutch systems for torque distribution.

Multi Clutch Problem Solutions

Multi clutch problem in car are but are not limited to the followings:

• Overheating: Multi-plate clutches can suffer from overheating under frequent stop and go situations in heavy traffic.
• Higher cost and complexity: The multiple friction discs makes the structure of multi-plate clutches more complex compared to single plate clutches because of multiple friction discs and steel plates. The manufacturing of multi-plate clutches are costlier, too.
• Premature wear: The friction material that clamps to the flywheel often fails because of frequent stop-and -go conditions in heavy traffic and because of aggressive driving.
• Clutch/ Judder or Vibration: During engagement the system with multi-plate clutches may experience vibration.
• Hydraulic issues: Often leaking in the cylinder results in sinking pedal and imperfect clutch engagement.

Used Car Buying Guide

If a used car has a multi-plate clutch system or not can be found in AutoHealth Vehicle History Report. AutoHealth Vehicle History is a holistic report on many aspects of a car. Along with other factors, it contains the maintenance history of the car. The latest ten maintenance histories are shown in detail. If ever a multi-plate clutch was serviced as part of routine maintenance or accident repair then the vehicle history will make clear that the car under investigation has multi-plate clutch.

Besides the report, a check by a trusted mechanic/ technician will reveal if the car has a multi-plate clutch in it.

FAQ

Does a multi-clutch system in a car make the car costlier?

Yes. The complexity of making multiple friction plates and steel plate separators cling to flywheels makes the process of manufacturing multi-plate clutches costlier. Also, the more plates need more materials which hikes the material cost of the part.

How Autohealth helps finding if a used car has a multi clutch system in cars?

The CarCheck feature of AutoHealth generates Vehicle History Reports. If the Vehicle History Report contains the maintenance record of the multi-plate clutch system in the car in its maintenance history section, then the user gets confirmation that the car under investigation has a multi clutch system.

Why is AutoHealth the one-stop guide of buying used cars?

The CarCheck feature of AutoHealth creates a holistic vehicle history report. In the vehicle history report there are sections about registration information of the vehicle and the owner information of the vehicle along with chassis number and engine number. Also, there are sections showing mechanical specifications of the car. Besides, there is information on maintenance and accident history. These are all that a buyer of a used car needs to know before buying a car.
