Modern cars are built with ingenious engineering, so you can just sit back and enjoy the ride. One of the most important modern innovations is the automatic transmission, but just how does an automatic transmission work? This smart system shifts gears perfectly every time, and you don't even have to lift a finger. Let's dive deeper into the mechanics of the modern automatic transmission, so you can see just how much goes on under the hood of your car!
Automatic vs. Manual
While automatic vehicles are more popular these days, manual vehicles used to be the only cars on the road. Manual transmissions require the use of a clutch, which enables the driver to shift up and down as necessary when speeding up or slowing down. The automatic transmission revolutionized this process by taking care of the shifting patterns for the driver. The clutch disappeared from the cabin, and drivers could just focus on the road ahead.
Components
Automatic transmissions use several components to operate effectively. In simple terms, these components work together to move fluids through the mechanical systems of the vehicle. This movement of fluid is known as "fluid coupling." The movement of these fluids transmits the mechanical power that your car needs to drive smoothly, and a set of gears shifts the vehicle as needed. But, how does each component work?
- Next to the engine of an automatic vehicle, you'll find the bell housing that contains a torque converter - which takes the place of the manual clutch.
- The torque converter utilizes its stator to deliver power, and even significantly multiply power, as it rotates and adjusts the flow of fluids through the converter's body.
- While the torque converter generates power, the planetary gear sets select the actual gear that you need. Depending on the fluid pressure generated by the converter, different gears of the planetary gear set will engage. This set your vehicle into the proper gear.
