A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine.

2021年3月4日 · Transmissions are important elements in mechanical engineering. Transmissions control the power supplied in favour of a high velocity (rotational speed) or in favour of a high force (torque)! In addition, transmissions also have the task of influencing the direction of rotation.

Several gearboxes, including manual, automatic, continuously variable transmission (CVT), automated manual/semi-automatic, and dual-clutch, each serving a unique purpose. The transmission is the mechanism that transmits power from the engine to …

A gearbox, also known as transmission, is a mechanical component that helps to transfer power from the engine to the wheels by using different gear ratios. It is usually located between the engine and the wheels, consisting of several gears, shafts and bearings.

In your vehicle, the gearbox and transmission work together to manage power from the engine to the wheels. However, they aren’t the same thing. Your gearbox, sometimes termed the “transmission box,” is an integral part of the larger transmission system, controlling power generated by the engine.

2024年6月10日 · Unlike a manual transmission, which has a set of multiple gears that make up the gear box, an automatic transmission has a one or more (usually more) planetary gear sets. Planetary gears have three sets of gears. The main gear is the sun gear, and it is in the center of the planetary carrier. The second set is the planetary gears.

A transmission system is more specifically referred to as the gearbox; in fact, the 5-speed transmission refers simply to the gearbox that uses gears and gear trains. Gears and gear trains provide speed and torque conversion from the rotating power source to another device.

2023年10月19日 · Torque modulation is achieved by selecting appropriately sized gears from those available in the gearbox. Apart from torque modulation, gearboxes also enable drive reversal; in other words, appropriate gearing allows wheels to move in reverse, rather than solely moving forward.

2018年8月2日 · How does a gearbox (transmission) work? The conversion of speed and torque takes place in gearboxes through the arrangement of gears or pulleys of different sizes. As explained in the article What is a transmission (gearbox) and what is it used for?, transmissions are used, among other things, to set the speed to a desired value.

From the early days of unsynchronized manuals to the sophisticated dual-clutch systems and hybrid-specific gearboxes, the evolution of transmissions highlights the innovative strides in automotive engineering. Let's delve into the myriad types of gearboxes and how they work.
