  • Transmission (mechanics) - Wikipedia

    Often the term transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device. In British English, the term transmission refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive), differential, and final drive shafts.

  • Gear - Wikipedia

    A gear or cogwheel is a rotating machine part having cut teeth, or in the case of a cogwheel, inserted teeth (called cogs), which mesh with another toothed part to transmit torque.Geared devices can change the speed, torque, and direction of a power source.Gears almost always produce a change in torque, creating a mechanical advantage, through their gear ratio, and thus may be considered a ...

  • How automatic gearboxes work | How a Car Works

    Most modern automatic gearboxes have a set of gears called a planetary or epicyclic gear train.. A planetary gear set consists of a central gear called the sun gear, an outer ring with internal gear teeth (also known as the annulus, or ring gear), and two or three gears known as planet gears that rotate between the sun and ring gears.. The drive train is coupled to a mechanism known as a ...

  • Locking differential - Wikipedia

    A locking differential is designed to overcome the chief limitation of a standard open differential by essentially "locking" both wheels on an axle together as if on a common shaft. This forces both wheels to turn in unison, regardless of the traction (or lack thereof) available to either wheel individually. When the differential is unlocked (open differential), it allows each wheel to rotate ...

  • How the transmission works | How a Car Works

    Front-wheel-drive cars use the same transmission principles as rear-wheel-drive cars, but the mechanical components vary in design according to the engine and gearbox layout. Transverse engines are normally mounted directly above the gearbox, and power is transmitted through the clutch to the gearbox by a train of gears.

  • Worm drive - Wikipedia

    Worm gears are used on many lift/elevator and escalator-drive applications due to their compact size and the non-reversibility of the gear. In the era of sailing ships, the introduction of a worm drive to control the rudder was a significant advance. Prior to its introduction, a rope drum drive controlled the rudder.
