Forklift Torque Converters
Forklift Torque Converter - A torque converter in modern usage, is usually a fluid coupling which is utilized in order to transfer rotating power from a prime mover, like for instance an electric motor or an internal combustion engine, to a rotating driven load. Similar to a basic fluid coupling, the torque converter takes the place of a mechanized clutch. This allows the load to be separated from the main power source. A torque converter can offer the equivalent of a reduction gear by being able to multiply torque whenever there is a significant difference between input and output rotational speed.
The most popular kind of torque converter utilized in auto transmissions is the fluid coupling kind. During the 1920s there was even the Constantinesco or pendulum-based torque converter. There are various mechanical designs utilized for constantly variable transmissions that have the ability to multiply torque. Like for instance, the Variomatic is a version 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 extra part that is the stator. This alters the drive's characteristics all through occasions of high slippage and produces an increase in torque output.
Within a torque converter, there are a minimum of three rotating components: the turbine, so as 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 can alter 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 whichever situation and this is where the term stator starts from. In point of fact, the stator is mounted on an overrunning clutch. This design stops the stator from counter rotating with respect to the prime mover while still permitting forward rotation.
In the three element design there have been changes which have been integrated at times. Where there is higher than normal torque manipulation is required, changes to the modifications have proven to be worthy. More often than not, these modifications have taken the form of multiple turbines and stators. Each set has been intended to produce differing amounts of torque multiplication. Various examples include the Dynaflow that makes use of a five element converter in order to generate the wide range of torque multiplication considered necessary to propel a heavy vehicle.
Different automobile converters include a lock-up clutch to reduce heat and so as to improve the cruising power and transmission effectiveness, even though it is not strictly part of the torque converter design. The application of the clutch locks the impeller to the turbine. This causes all power transmission to be mechanical which eliminates losses associated with fluid drive.
