What is a Flywheel?
A flywheel is a round, heavy metal disk that helps your car’s engine work smoothly. It stores energy from the engine and keeps it balanced, making sure the engine runs steadily without sudden stops or jerks. In manual cars, the flywheel connects the engine to the clutch, helping transfer power to the transmission. In automatic cars, a similar part called a flexplate does the same job. The flywheel also plays a key role in starting the engine, as the starter motor uses it to crank the engine when you turn the key. Simply put, the flywheel helps your engine run smoothly and keeps everything working in sync.
Difference Between Flywheel & Flexplate
A flywheel and a flexplate are both parts of a car’s drivetrain, but they serve slightly different purposes depending on the type of transmission. A flywheel is used in manual cars. It’s a heavy, solid metal disk that connects the engine to the clutch, stores energy, and helps keep the engine running smoothly. It also has a surface that the clutch presses against to transfer power to the transmission.
A flexplate, on the other hand, is used in automatic cars. It’s thinner and lighter than a flywheel and connects the engine to the torque converter instead of a clutch. The flexplate still helps transfer power, but its main role is to ensure the engine and transmission work together in an automatic system.
The main difference is that flywheels are designed for manual transmissions, while flexplates are made for automatic transmissions. Both are essential for their respective systems to function properly.
