Fordonstransmission

Fordonstransmission is a system in motor vehicles that transmits power from the engine to the drive wheels and modulates torque and speed. The term broadly covers manual, automatic, continuously variable (CVT), and dual-clutch transmissions, as well as automated manuals. It enables the engine to operate in its optimal RPM range while providing the driver or vehicle control over acceleration and speed.

Key components include the gearbox, which houses gear sets; a clutch or torque converter; hydraulic or electronic actuators; a final drive; and a control unit. Manual transmissions use a clutch and synchronizers to engage gears; automatics use a torque converter and planetary gear sets; CVTs use a belt or chain with variable pulleys; dual-clutch transmissions use two separate clutches for even/odd gears.

Operation: driver selects a gear or the transmission controller selects; power is transmitted through the chosen path; gear ratios determine torque multiplication and output speed. Efficiency, smoothness, and performance depend on design and control strategies.

Maintenance: requires transmission fluid changes and checks for leaks; symptoms of problems include rough shifting, slipping, noises, or delayed engagement.
