Torque converter: The underestimated hero of the automatic transmission!

Automatic transmission and its key component, the torque converter, remain indispensable despite the growing competition from electric vehicles and double clutch transmission. The combustion engine shows its weaknesses in particular when starting starts, since it can only develop its performance through speed. Here the torque converter comes into play, which connects the engine and gearbox via a special oil system and thus ensures a gentle end. This is particularly advantageous if vehicles have to start slowly, for example when parking or maneuvering, as it describes krone.at .

functionality of the torque converter

The torque converter uses a tough liquid that is set in motion by a pump wheel. This current activates a fixed guiding bike and leads to a turbine wheel that forwards the power to the gear. This allows the vehicle to be set in motion before the engine and the transmission reach the same speed. The converter bridging (Wük) becomes active when the leather is separated. This technique has the advantage that it is less susceptible to wear, which makes it particularly popular with commercial vehicles, such as "https://aftermarket.zf.com/de/aftermarket-Portal/expert-blog/kurzerklaert-sachs--wrehmentwandler/"> aftermarket.zf.com The main components of the torque converter are particularly noteworthy: the pump wheel, the turbine wheel, the LeTrad with a disposable free run and the integrated converter bridging coupling. This construction improves power transmission and increases driving comfort by reducing vibrations. Overall, vehicle operation becomes more efficient, even if the automatic is affected with a certain inefficiency: So far, this technology has been increasingly used for vehicles that have to prove itself in the trailer operation. With the growing trend towards electrical drives, however, the technology of the torque converter faces new challenges, but still remains a valuable option in the area of hybrid drives and with many new car models.
