The automotive industry, which is not indifferent to technological developments, makes progress towards environmentally friendly, fuel-saving and driving comfort activities. Depending on these developments, the flywheel system that plays a role in internal combustion engines has also improved. The dual mass flywheel, which is used as an interconnection element in distributing the engine power to the system, provides many advantages in terms of driving comfort and vehicle performance compared to the single-mass flywheel system.
Although it undertakes similar tasks with the single-mass flywheel system, since a pre-installed spring system is used between the masses in the dual-mass flywheel system, the negativities caused by the fluctuations created by the crankshaft are eliminated in the system. This provides less vibration and more comfortable driving pleasure.
What is a Dual Mass Flywheel?
The interconnection element, colloquially called flywheel in the automotive industry, is found in all internal combustion vehicles without exception. The location of the flywheel in the vehicle is between the crankshaft and the gearbox. It undertakes the task of transmitting the rotational force received from the crankshaft to the gearbox within the system.
While a single-mass flywheel requires pressure and lining components to transfer power, a dual-mass flywheel transfers power smoothly thanks to its spring damper system components. Since the system uses two different masses, it is defined as a dual mass flywheel.
Dual Mass Flywheel Components
Dual mass flywheel, which undertakes similar tasks with other flywheel types, differs from other types in terms of its structure.
In the system component;
o Dual mass flywheel,
o Dental cavity,
o Pulse sensor disk,
o Gear,
There are such personnel. The spring damper located within the flywheel masses acts between the first mass and the second mass and undertakes the task of sending the torsional vibration produced in the engine to the transmission. As can be seen in other flywheel systems, there is a flywheel gear in the dual mass system. In this way, the first movement provided by the starter dynamo is transmitted to the crank system and the first movement of the vehicle is achieved.
Differences between Single and Dual Mass Flywheels
Although there is no difference between single and dual mass flywheels in terms of clutch time, it has been observed that the dual mass system carries out the process more smoothly during gear shifting. In this way, the gripping process takes place more smoothly. Even when the vehicle is running at a speed close to idle, the vibrations are dampened by the springs within the dual-mass flywheel system. However, such fluctuations cannot be damped sufficiently in classical flywheel systems.
How Does a Dual Mass Volat Work?
The dual mass flywheel system works similarly to classical flywheel systems. It works in conjunction with the clutch system and provides the transfer of torsional force with a rigid clutch disc without vibration dampers.
There is a spring or gear system within the flywheel system. One of the masses is placed on the crank, and the other mass forms the transmission connection point. Fixed parts and moving parts can rotate in different directions up to 120 degrees depending on the operating condition of the vehicle. This plays an important role in eliminating concussion.
What are Dual Mass Flywheel Failures?
As with other flywheel failures, it is possible to feel dual mass flywheel failures. If the vehicle makes noise when idling and stops when the clutch is pressed, it may be a flywheel failure.
If precautions are not taken in time, the fault situation develops further and warns the driver with a different sound when the clutch is pressed. If disturbing sounds occur when the engine operates at different speeds, ange indicate a problem in the flywheel system.it may be associated with a flywheel failure.
