Forklift Torque Converter
Torque Converter for Forklifts - A torque converter is a fluid coupling that is used in order to transfer rotating power from a prime mover, which is an internal combustion engine or as electrical motor, to a rotating driven load. The torque converter is similar to a basic fluid coupling to take the place of a mechanized 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 if there is a significant difference between input and output rotational speed.
The most common type of torque converter used in car transmissions is the fluid coupling model. In the 1920s there was even the Constantinesco or pendulum-based torque converter. There are various mechanical designs utilized for constantly changeable transmissions which 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 is incapable of multiplying torque. A torque converter has an added component which is the stator. This alters the drive's characteristics all through times of high slippage and produces an increase in torque output.
There are a at least three rotating parts inside a torque converter: the turbine, that drives the load, the impeller, which is mechanically driven by the prime mover and the stator, that is between the turbine and the impeller so that it could alter oil flow returning from the turbine to the impeller. Usually, the design of the torque converter dictates that the stator be stopped from rotating under any condition and this is where the term stator originates from. In reality, 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 enabling forward rotation.
In the three element design there have been changes which have been incorporated sometimes. Where there is higher than normal torque manipulation is considered necessary, alterations to the modifications have proven to be worthy. Most commonly, these modifications have taken the form of several stators and turbines. Every set has been designed to produce differing amounts of torque multiplication. Various instances comprise the Dynaflow that uses a five element converter in order to generate the wide range of torque multiplication required to propel a heavy vehicle.
Different car converters comprise a lock-up clutch to be able to lessen heat and to improve the cruising power and transmission effectiveness, even if it is not strictly component 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.
