The transmission gets power directly from the engine.
The engine generates rotational power, and this power is then transferred to the transmission. Let's break down the process:
-
Engine Output: The engine's crankshaft, driven by the combustion process, spins. This spinning motion represents the engine's power output.
-
Connection to the Transmission: The engine's crankshaft is connected to the transmission, typically through a flywheel or flexplate and a clutch (in manual transmissions) or a torque converter (in automatic transmissions).
-
Manual Transmission: The clutch allows the driver to engage or disengage the engine from the transmission, allowing for gear changes. When engaged, the engine's power flows directly to the transmission's input shaft.
-
Automatic Transmission: The torque converter uses fluid dynamics to transfer power from the engine to the transmission. It also provides torque multiplication, especially at lower speeds.
-
-
Transmission Input: The power from the engine enters the transmission through the input shaft. This shaft is the starting point for the transmission's gear system.
Once the power is inside the transmission, the various gears and other components manipulate the speed and torque to drive the wheels. The transmission essentially acts as an intermediary between the engine and the wheels, optimizing the engine's power output for different driving conditions.
In summary, the engine is the source of power, and it is directly coupled to the transmission to initiate the process of transferring that power to the wheels.
