Torque Converters for Forklift - A torque converter in modern usage, is normally a fluid coupling that is used so as to transfer rotating power from a prime mover, like for example an internal combustion engine or an electrical motor, to a rotating driven load. Like a basic fluid coupling, the torque converter takes the place of a mechanical clutch. This allows the load to be separated from the main power source. A torque converter can provide the equivalent of a reduction gear by being able to multiply torque whenever there is a considerable difference between output and input rotational speed.
The fluid coupling kind is actually the most common kind of torque converter utilized in car transmissions. During the 1920's there were pendulum-based torque or likewise called Constantinesco converter. There are other mechanical designs used for constantly changeable transmissions that could multiply torque. Like for example, the Variomatic is one type that has a belt drive and expanding pulleys.
A fluid coupling is a 2 element drive that could not multiply torque. A torque converter has an additional part which is the stator. This changes the drive's characteristics all through times of high slippage and produces an increase in torque output.
In a torque converter, there are at least of three rotating parts: the turbine, in order to drive the load, the impeller that is driven mechanically driven by the prime mover and the stator. The stator is between the impeller and the turbine so that it could alter oil flow returning from the turbine to the impeller. Normally, the design of the torque converter dictates that the stator be stopped from rotating under whichever condition and this is where the word stator starts from. Actually, the stator is mounted on an overrunning clutch. This particular design stops the stator from counter rotating with respect to the prime mover while still enabling forward rotation.
Modifications to the basic three element design have been integrated at times. These adjustments have proven worthy especially in application where higher than normal torque multiplication is needed. More often than not, these modifications have taken the form of multiple turbines and stators. Each and every set has been designed to generate differing amounts of torque multiplication. Some examples include the Dynaflow that uses a five element converter so as to generate the wide range of torque multiplication considered necessary to propel a heavy vehicle.
Even though it is not strictly a component of classic torque converter design, different automotive converters include a lock-up clutch in order to reduce heat and so as to enhance cruising power transmission efficiency. The application of the clutch locks the turbine to the impeller. This causes all power transmission to be mechanical that eliminates losses associated with fluid drive.
