Forklift Torque Converter - A torque converter in modern usage, is commonly a fluid coupling that is utilized to transfer rotating power from a prime mover, for example an electric motor or an internal combustion engine, to a rotating driven load. Like a basic fluid coupling, the torque converter takes the place of a mechanical clutch. This enables 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 input and output rotational speed.
The most common type of torque converter utilized in automobile transmissions is the fluid coupling model. During the 1920s there was even the Constantinesco or likewise known as pendulum-based torque converter. There are other mechanical designs for constantly variable transmissions that have the ability to multiply torque. Like for example, the Variomatic is a version which has a belt drive and expanding pulleys.
A fluid coupling is a 2 element drive that is incapable of multiplying torque. A torque converter has an extra part that is the stator. This alters the drive's characteristics all through occasions of high slippage and generates an increase in torque output.
There are a minimum of three rotating components in a torque converter: the turbine, that drives the load, the impeller, that is mechanically driven by the prime mover and the stator, that is between the impeller and the turbine so that it can change oil flow returning from the turbine to the impeller. Traditionally, the design of the torque converter dictates that the stator be prevented from rotating under whatever condition and this is where the term stator starts from. In truth, the stator is mounted on an overrunning clutch. This particular design prevents the stator from counter rotating with respect to the prime mover while still permitting forward rotation.
In the three element design there have been alterations that have been incorporated at times. Where there is higher than normal torque manipulation is required, modifications to the modifications have proven to be worthy. Most commonly, these alterations have taken the form of many turbines and stators. Every set has been meant to produce differing amounts of torque multiplication. Some instances comprise the Dynaflow which makes use of a five element converter to be able to generate the wide range of torque multiplication required to propel a heavy vehicle.
Although it is not strictly a part of classic torque converter design, various automotive converters comprise a lock-up clutch in order to lessen heat and in order 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 connected with fluid drive.
