A Gear Box is an assembly consisting of various gears, synchronizing sleeves, and a gear-shifting mechanism fitted inside a metal housing. Of which the gearbox is an integral part.

Explained with diagrams. And also you can download the PDF format file of this article. It may be a gearbox, a torque converter, overdrive , fluid drive, or hydraulic drive. The purpose of the transmission is to provide high torque at the time of starting, hill climbing, accelerating, and pulling a load. When a vehicle is starting from rest, hill climbing, accelerating, and meeting other resistance, high torque is required at the driving wheels.

An automatic transmission seems pretty simple; after all, you just put it in Drive and go. But as with most things automotive, a lot of complexity goes into making it look easy. The engine contains a heavy central crankshaft cylinder that spins, which provides the power to turn the wheels. The transmission is the vital link, increasing torque to accelerate away from a stop, or preventing the engine from working too hard at highway speeds. An automatic transmission uses sensors to determine when it should shift gears, and changes them using internal oil pressure. While there are numerous components stuffed into the transmission, and their actual operation is a bit more complicated than the simplified version presented here, the key components are the torque converter and planetary gearsets. In order to shift gears, the transmission must be temporarily disconnected from the engine.

Romina Ronquillo. Gears are toothed, mechanical transmission elements used to transfer motion and power between machine components, and in this article, we discuss the different types of gears available and how gears work. Operating in mated pairs, gears mesh their teeth with the teeth of another corresponding gear or toothed component which prevents slippage during the transmission process. Each gear or toothed component is attached to a machine shaft or base component, therefore when the driving gear i. Depending on the design and construction of the gear pair, the transference of motion between the driving shaft and the driven shaft can result in a change of the direction of rotation or movement. Additionally, if the gears are not of equal sizes, the machine or system experiences a mechanical advantage which allows for a change in the output speed and torque i.

Here are the different types of Automatic Transmissions

This is a transmission that uses a torque converter, planetary gearset and clutches or bands to shift through a vehicle's forward gears automatically. Some automatics allow the driver a limited amount of manual control over the vehicle aside from choosing a forward, reverse or neutral mode -- for example allowing the driver to control upshifts and downshifts by utilizing buttons or paddles on the steering wheel or the gear selector. Common names for such transmissions are "shiftable automatic," "Tiptronic" and "autostick. With a manual transmission, the driver selects all gears manually using both a movable gear selector and a driver-operated clutch. This type of transmission is also known as a "stick shift" or a "standard" transmission. See Manual Transmission Basics for more information.

Internal-combustion engines run at high speeds, so a reduction in gearing is necessary to transmit power to the drive wheels, which turn much more slowly. The gearbox provides a selection of gears for different driving conditions: standing start, climbing a hill, or cruising on level surfaces. The lower the gear, the slower the road wheels turn in relation to the engine speed. The gearbox is the second stage in the transmission system, after the clutch. It is usually bolted to the rear of the engine , with the clutch between them. Modern cars with manual transmissions have four or five forward speeds and one reverse, as well as a neutral position. The gear lever , operated by the driver, is connected to a series of selector rods in the top or side of the gearbox.

What are the different types of transmissions?

In one of my previous articles, we learned what are gearboxes, their main parts, why do we need them and their working in detail.

Traditional Automatic Transmission

В его голове смешались мысли о кольце, о самолете Лирджет-60, который ждал его в ангаре, и, разумеется, о Сьюзан. В тот момент, когда он поравнялся с сиденьем, на котором сидела девушка, и подумал, что именно ей скажет, автобус проехал под уличным фонарем, на мгновение осветившим лицо обладателя трехцветной шевелюры. Беккер смотрел на него, охваченный ужасом. Под густым слоем краски он увидел не гладкие девичьи щеки, а густую щетину. Это был молодой человек. В верхней губе у него торчала серебряная запонка, на нем была черная кожаная куртка, надетая на голое тело. - Какого черта тебе надо? - прорычал он хриплым голосом - с явным нью-йоркским акцентом.

Велел ему сегодня не приходить. Он ничего не сказал о том, что поменялся с тобой дежурством. У Чатрукьяна ком застрял в горле. Он молчал. - Ну ладно, - вздохнул Стратмор.

Кроме того, тот старик вроде бы обо всем позаботился. - Канадец. - Да.

 Некоторые идеи о протоколах вариативных фильтров и квадратичных остатках. - Стопроцентный бестселлер. Она засмеялась. - Сам удивишься. Дэвид сунул руку в карман халата и вытащил маленький предмет.
