Is the Transmission the Same as the Gearbox?
1 Answers
Transmission is indeed the same as the gearbox, also referred to as the gear case. Inside the transmission, gears of different sizes mesh together to increase or decrease rotational speed or torque, thereby enabling the vehicle to change gears. The meshing of gears resembles the interlocking of human teeth, hence the term "gearbox." Transmissions are categorized into manual and automatic transmissions. Manual transmissions include 5-speed manual and 6-speed manual, while automatic transmissions comprise 6-speed automatic, 7-speed dual-clutch, 8-speed semi-automatic, and CVT (continuously variable transmission). The transmission consists of a gear shifting mechanism and a control mechanism, with some vehicles also featuring a power take-off unit. Transmissions can be further classified into stepped, stepless, and integrated types, serving functions such as enabling reverse driving, interrupting power transmission, and altering gear ratios.
