Matching RPM and Gears in Manual Transmission?
1 Answers
Manual transmission vehicles require proper gear-speed synchronization as follows: 1st gear at 15 km/h; 2nd gear at 25 km/h; 3rd gear at 35 km/h; 4th gear at 55 km/h; 5th gear at 65 km/h or above. Manual transmission, also called manual gearbox, represents a fundamental type of automotive transmission system. Its primary function is to alter the gear ratio (also known as the torque ratio) by utilizing larger-diameter low-gear wheels based on the lever principle's torque mechanism, thereby amplifying engine torque to initiate vehicle movement. A manual transmission consists of three core components: the gear mechanism, transmission housing, and shift linkage assembly.
