Forklift Torque Converter - A torque converter in modern usage, is commonly a fluid coupling that is utilized so as to transfer rotating power from a prime mover, for instance 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 mechanized 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 when there is a considerable difference between input and output rotational speed.
The fluid coupling unit is actually the most popular 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 for always variable transmissions which have the ability to multiply torque. Like for example, the Variomatic is one type which has expanding pulleys and a belt drive.
The 2 element drive fluid coupling cannot multiply torque. Torque converters have an element called a stator. This alters the drive's characteristics all through occasions of high slippage and produces an increase in torque output.
Inside a torque converter, there are a minimum of three rotating components: the turbine, to drive the load, the impeller that is driven mechanically driven by the prime mover and the stator. The stator is between the turbine and the impeller so that it can change oil flow returning from the turbine to the impeller. Usually, the design of the torque converter dictates that the stator be prevented from rotating under any situation and this is where the word stator begins from. In truth, the stator is mounted on an overrunning clutch. This design stops the stator from counter rotating with respect to the prime mover while still allowing forward rotation.
Changes to the basic three element design have been integrated at times. These changes have proven worthy especially in application where higher than normal torque multiplication is needed. More often than not, these alterations have taken the form of various stators and turbines. Every set has been meant to produce differing amounts of torque multiplication. Some examples comprise the Dynaflow that utilizes a five element converter so as to generate the wide range of torque multiplication considered necessary to propel a heavy vehicle.
Various auto converters comprise a lock-up clutch to be able to lessen heat and to improve the cruising power and transmission efficiency, even though it is not strictly part of the torque converter design. 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.
