VEHICHLE TRANSMISION SYSTEM

Transmission system, in automotive, is a system that becomes energy from engine to differential and axis. By twisting, the wheels can spin and drive the car. Transmission is necessary because the combustion engine commonly used in cars is an internal combustion engine that produces rotation (rotation) between 600 to 6000 rpm. Whereas, the wheels rotate at a rotational speed between 0 to 2500 rpm. Currently, there are two common transmission systems, namely manual transmission and automatic transmission. There are also transmission systems that are combined between the two systems, but this is the latest development that can only be found in high-tech cars and certain brands only. Manual transmission is one type of transmission that is widely used for reasons of easier maintenance. Usually on manual TRANSMISIONS consists of 3 to 7 speed. Automatic transmission consists of 3 main parts, namely: Torque converter, Planetary gear unit, and Hydraulic control unit.

Torque converter serves as an automatic clutch and can enlarge the engine moment. While Torque converter consists of Pump impeller, Turbine runner, and Stator. Which is where the Stator is located between the impeller and the turbine.Torque converter is charged with ATF (Automatic Transmition Fluid). The engine moment is moved in the presence of fluid flow. Actually the same as the regular Automatic system, but we can move the gears themselves with the lever. Slightly more expensive than regular matic. Mercedes already has a 7 AT system. Advantages: comfort matic but we can move your own gear. Weakness: same as ordinary matic, less responsive. Now there are no cars that use this system. Like a matic system, but using a variable belt so the ration can be changed. Actually only have one tooth or often called not toothed. Audi call it Multitronic, other manufacturers also have their own names2 but all the same. There are also who use it to deceive customers like Honda with its '7-speed Steermatic' system. Unlike the Mercedes 7 AT that actually has 7 genuine teeth, Steermatic Honda is only change2 ratio belt only. Compare it with Tiptronic, the power response is far less.

Because the CVT system has a linear power curve. Gearshift 'does not feel'. Actually it is not 'not felt', but because there really is NO TEET MOVING because it only has one tooth. More efficient than regular matic because it does not use torque converter. Very unsuitable for performance car. Power is unresponsive, less responsive by ordinary matic though. At regular matic so in-kickdown directly down gear, while the CVT only change the ratio belt only. Case example: match Vios (4AT) vs City (CVT). Manual transmission of clutch arranged by computer, can shift gears in just a fraction of a second. There is no clutch pedal, and there must be a PADDLE behind the wheel to move the gear. Distinguish the 'gear button' on tiptronic or CVT, PADDLE is not a button on the steering wheel but a kind of lever behind the steering wheel. There is an 'auto' mode, it can move its own gear like a regular matic, but not as smooth as a regular matic as it remains a manual transmission.

In 'auto mode' and incoming gear position, if not brake the car will not move forward itself because this system is manual and not matic, there is no torque converter. Used only optional on hi-performance sports cars. Advantages: responses are even faster than regular manuals, even if moved by a professional racer though. Weaknesses: in "auto" mode, gearshift is not so smooth and sometimes noticeable, especially in stop-and-go conditions that are not suitable for sports cars. Example: Transmission of F1 cars, BMW's SMG Transmission, Ferrari's Sequential F-1, SMT (Toyota, on MRS spider) and E-Gear (Lamborghini). The system was originally regarded as 'the future', before the advent of double-clutch gearbox technology (look below). Now it's getting abandoned due to many uncomfortable complaints on its auto mode. Manual transmission of clutch is set computer like Sequential Manual above, but the main difference is, using TWO CLUTCH, whose job is to handle two different teeth: the teeth being used, and the teeth to be entered. Two clutches allow it to enter the next gear even when the first tooth has not been fully removed. The gearshift is not felt, as in CVT, but the big difference is, its power is even more responsive than ordinary manual. New VW Group that already use this system, they call it DSG. BMW and Porsche are still preparing their respective versions (ZSG for BMW, PDK for Porsche).
