Automatic Transmission Technology, Evolution Plus Electronic Mechanical

Filed under: definition

Starting from a costly transmission known alias just for the rich, because it is only available on luxury cars with strangling care. Until a gearbox that has been unpopular, are almost evenly on the entire car variants.

Call it the Toyota Avanza Daihatsu Xenia or that provide an automatic transmission is also on staff. Even many who only provide a smart transmission model. Take for example the Honda Freed or a Suzuki Grand Vitara, not to mention the premium cars like Mercedes-Benz or BMW.

Various models of this smart tranmisis changed. Starting from the conventional hydraulic type, which later evolved into a hydraulic-electronic mechanical developments to emerge. As the presence of CVT, AMT or DSG.

Hydraulic CONVENTIONAL

This technology is widespread at the beginning of automatic-automatic. For example the automatic gearbox on a Mercedes-Benz, BMW, Toyota. Conventionally regarded as the gearshift only be set using the alias ATF automatic transmission oil pressure.

For example on gear 1, as rising oil pressure was elevated rpm. So that the oil pressure opens the valve for a higher gear. Valve itself restrained by a computed will open if the pressure rises to a certain value.

Although there is an electronic solenoid, still simple. “The average elektronisnya only for OD (overdrive, red) as in the Toyota Cressida and the Crown,” said Encik Mohammad Holil, Wani Matic boss in Pinang Griya Permai, Ciledug. While the automatic Honda or Mercedes-Benz is wearing the D4 model, there is no electronic valves for OD.
Electric hydraulic

Along with the development of injection car, automatic with electronic management is growing. Take for example the Mitsubishi Galant Eterna and have full electronically. “If the module is damaged, will limp home and stuck in gigi3,” commentator guy is 39 years.

Mercedes introduced the automatic generation of full electronic on New Eyes. Toyota started the electronic automatic on All New Corolla or Camry. It was still wearing kick-down cable on first generation.

While Honda is still a little conventional. “Basically regular automatic, but there is a safety reverse gear. If you do not accidentally move to the ‘R’ when the road ahead, auto matic ngelos, “he explained. There are two solenoid control module on this gearbox. Although the module is removed, the automatic stay could work, but the feature did not work.

Now, with full electronic gearbox, present other features such as a Steptronic or tiptronic manual gear shift allows the rider. But in construction, the automatic transmission remains

Transmission System in Car Engine
CVT

The first known output at Fiat Uno Selecta 1992. But more crowded in the ear pinned to the public since the Honda Jazz and City. Then there is also the dimension of such cars on the New Nissan X-Trail and Teana.

No tooth wear, because the transmission ratio obtained from the two main pulleys. So the Honda Jazz comparisons can be made up to 7-Speed.
AMT

Short for Automated Manual Transmission. In principle, this gearbox is a manual transmission that made gear shifting system and the electronic clutch lever. So, it’s the manual gearbox with a motor attached on it. Can be found on the Proton Savvy, also Peugeot 206 and 207 2-Tronic.
DSG

Alias ​​Dual Clutch Gearbox. The principle is also a manual transmission with two clutch. A tooth for tooth odd and one even. Gearshift is set electronically for selecting gear and the clutch is activated. So the driver is more practical, can drive like a drive automatic. For example the Ford Fiesta. There also are providing manual gear shifting like the Ford Focus TDCi.
