How Does a Manual Transmission Work?

[DiAlexis]

Manual transmission works by utilizing the combination of gears with different tooth counts to achieve changes in speed and torque. Below is more related information: 1. Manual Transmission: A manual transmission is a gear-shifting device used to alter the speed and torque transmitted from the engine to the drive wheels. It enables the vehicle to achieve varying traction and speed under different conditions such as starting from a standstill, climbing hills, turning corners, and accelerating, while also allowing the engine to operate within a more favorable range. 2. Components of a Manual Transmission: A manual transmission consists of two main parts: the gear-shifting mechanism and the gear-shifting control mechanism. The gear-shifting mechanism primarily includes the input shaft, output shaft, reverse gear shaft, various gear sets, synchronizers, bearings, and housing, with some models also featuring an intermediate shaft. Its function is to alter torque, speed, and direction. The gear-shifting control mechanism mainly comprises the operating device, locking device, and cover, among others, and is responsible for completing gear-shifting operations. During gear shifting, especially when downshifting from a higher gear to a lower gear, impacts between gear teeth or spline teeth can easily occur. To prevent such impacts, synchronizers are installed in the shifting mechanism. Synchronization involves creating frictional contact between the teeth on the sleeve and the gear (blue) before engagement. The conical protrusion on the gear (blue) fits into the conical notch on the sleeve, and the friction between them ensures synchronization of the sleeve and the gear (blue). The outer part of the sleeve slides to engage with the gear.
