The differential has three functions: to turn the direction of drive through 90 degrees to the rear wheels; to allow either rear wheel to turn faster than the other when cornering; and to effect a final gear reduction . A pinion gear inside the differential is driven by the propeller shaft and has its gears bevelled - cut at an angle.

This increase is also referred to as transmission spread S and is calculated as follows: S = imax imin = 3.6 0.8 = 4.5 (5) (5) S = i m a x i m i n = 3.6 0.8 = 4.5. For the described gearbox, the spread is S = 4.5, which means that the gear ratio can be increased by a factor of 4.5 starting from the minimum value. Epicyclic gearing diagram, as used in hydraulic automatic transmissions A transmission (also called a gearbox) is a mechanical device which uses gears to change the speed or direction of rotation in a machine. [1] [2] Many transmissions have multiple gear ratios, but there are also transmissions that use a single fixed gear ratio. Visit me at: http://www.ericthecarguy.com/This is part one of my front wheel drive (FWD) automatic transmission dissection video. In this video I cover the. The diagram at left is a simple one from a 3-speed automatic from the '60s. The newer systems are much more complex and are combined with computerized electrical components. Transmission fluid serves a number of purposes including: shift control, general lubrication and transmission cooling.

Unlike a manual transmission, which has a set of multiple gears that make up the gearbox, 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. The automatic transmission diagram shows the parts of the transmission system, the connection between the torque converter, clutches, planetary gears, etc. You can get a more straightforward representation of the automatic transmission in a block diagram or 2D model.
The transmission ensures that your engine spins at an optimal rate (neither too slow nor too fast) while simultaneously providing your wheels with the right amount of power they need to move and stop the car, no matter the situation you find yourself in. Parts of an Automatic Transmission 1) Friction Clutch 2) Bands 3) Spring-Loaded Valve 4) Load Sensor 5) Shift Valve 6) Torque Converter 7) Seals and Gaskets 8) Gear Stick Parts of an Automatic Transmission Below is a list of the parts of an automatic transmission system.

Automatic Transmission, An Anatomy Lesson. Put simply, the modern automatic transmission is a marvel of engineering, pulling together multiple disciplines, including physics, hydraulics, electronics, and mechanical theory. Made up of hundreds of both moving and stationary parts, a bevy of sensors and solenoid valves, pumps, clutches, brakes. Operation of an Automatic Transmission. The most common type of automatic transmission uses hydraulic power to shift gears. According to How Stuff Works, this device combines a torque or fluid.
