So, if the driving gear has a diameter of 1 cm and the driven gear is 10 cm across, the gear train will increase the torque 10-fold while reducing the rotational speed by a factor of 10.

Traditional automatic transmissions use a torque converter attached to the flywheel at the rear of the engine's crankshaft to create a fluid coupling between the engine and transmission. The three ...

A less common option is the automated manual transmission (AMT). Sometimes called a semi-automatic transmission, this model pairs the clutches and gears of a manual transmission with a set of ...

Power transmission transfers mechanical power. Gear trains change speed/torque. Idler gears reverse rotation. Belts/pulleys and chains/sprockets transfer motion efficiently.

Torque vectoring is a relatively new technology that has been employed in automobile differentials, most commonly all-wheel-drive vehicles, that allows the amount of power sent to each wheel to be ...
