Automatic {gears|feeds} contain many gears {in a variety of|in several|in numerous} combinations. In {a hands-on|a tutorial|a normal} transmission, gears slide along shafts as you move the shift lever from one position to another, engaging various sized {equipment|things|armor and weapon upgrades} as required to source the correct gear {percentage|proportion|rate}.
In an {programmed|computerized} {tranny|transmitting|indication}, however, the gears are never physically moved and are always engaged to the same gears. This kind of is accomplished through the use of planetary {equipment|products|items} sets.Planetary Gear Sets
The basic planetary gear set {contains|involves} a sun gear, {a band|an engagement ring|a diamond ring} gear and several {world|globe|entire world} gears, all remaining in {regular|frequent} mesh. {Our planet|The entire world|The environment} {equipment are|things are|armor and weapon upgrades are} {linked} to {the other person} through a common {company|transporter|jar} which allows the {equipment|things|armor and weapon upgrades} to spin on shafts called "pinions" which are attached to the {company|transporter|jar}.
One example of a way that this system can {be applied is|be taken is|provide is} by {linking|hooking up|attaching} the ring gear to the input shaft {arriving|approaching} from the engine, {linking|hooking up|attaching} the planet carrier to the outcome shaft, and locking {sunlight|the sunlight|direct sunlight} gear so that it can't move. In this scenario, when we turn the {band|engagement ring|diamond ring} gear, the planets will "walk" over the {sunlight|sunshine} gear (which is {kept|placed|organised} stationary) {creating|triggering} {our planet|the entire world|the environment} {company|transporter|jar} to turn the {result|end result|outcome} shaft in the same direction as the {insight|suggestions|type} shaft but at a slower speed {creating|triggering} {equipment|products|items} reduction (similar to a car in first gear).
If we unlock the sun gear and {secure|locking mechanism|fasten} any two elements {collectively|jointly|along}, this will cause all three elements to {change|switch|convert} at the same {velocity|rate|acceleration} {so the|in order that the} output shaft will turn at the same rate of speed as the input shaft. This kind of is like a car that is in third or high gear. {An additional|One more|One other} way that we {may use|are able to use} a Planetary gear {collection is|place is|set in place is} by locking the planet carrier from moving, then applying capacity to the ring gear {which will allow|causing} the sun gear to turn in the {reverse|opposing|contrary} direction giving us {invert|change} gear.
The illustration on the right shows how the simple system {explained|referred to|defined} above would look in {a real|a proper} transmission. The {insight|suggestions|type} shaft is {linked} to the ring gear (Blue), The outcome shaft is {linked} to the {world|globe|entire world} carrier (Green) {which|and this is} {linked} to a "Multi-disk" {clutch system|clutch i465 black|clutch i465} pack. The sun {equipment is|products is|items is} {linked} to another container (yellow) which is also {linked} to the other half of the clutch pack. Surrounding the exterior of the carol is a band (red) that can be {stiffened|more strict} around the drum when {necessary to|needed to|instructed to} prevent the carol with the attached {sunlight|sunshine} gear from turning.
The clutch pack is used, in this instance, to lock the planet {company|transporter|jar} with {sunlight|the sunlight|direct sunlight} gear {making|driving|pushing} both {to show|to choose} at the same speed. If {both|the|the two} clutch pack and the band were released, {the device|the machine|the program} would be in {natural|simple}. Turning the input {base|canal} would turn the {world|globe|entire world} gears {up against the|resistant to the} sun {equipment|products|items}, but since nothing is holding the sun {equipment|products|items}, it will just rotate free and have no effect on the {end result|result|final result} shaft. To place the unit in first {equipment|products|items}, the band is applied to hold the {sunlight|sunshine} gear from moving. To shift from first to high gear, the {music group is|strap is|group is} released and the clutch is applied {creating|triggering} the outcome shaft to turn at the same speed as the {insight|suggestions|type} shaft.
Many more {mixtures are|combos are|blends are} possible using two or more planetary {units|models|pieces} {linked} in various ways to provide {the several|different} {ahead|forwards|front} speeds and reverse that {are located|are normally found|are simply} in modern {programmed|computerized} transmissions.
Some of the clever gear arrangements found in four and now, five, six and even seven and eight-speed automatics are complex enough to make a technically clever lay person's head rotate trying to understand the flow of power through the transmission as it shifts from first {equipment|products|items} through top gear while the vehicle accelerates to highway speed. On modern vehicles (mid '80s to the present), the vehicle's computer monitors and {settings|handles|adjustments} these shifts so that they are almost {impasible|invisible|sordo}
