How Does a Manual Car Transmission Work?
1 Answers
The working principle of a manual car transmission involves the combination of gears with different tooth counts meshing together to achieve changes in rotational speed and torque. A manual transmission, also known as a mechanical transmission, requires the driver to manually shift the gear lever to alter the gear meshing positions inside the transmission, thereby changing the gear ratio to achieve speed variation. Most passenger car manual transmissions are four-speed or five-speed stepped gear transmissions, typically equipped with synchronizers for smoother and quieter gear shifting. A manual transmission is a speed-changing device that allows the vehicle to obtain varying levels of traction and speed under different operating conditions, such as starting from a standstill, climbing hills, turning corners, or accelerating, while also keeping the engine operating within a more favorable range.
