Torque Converters for Forklifts
Forklift Torque Converters - A torque converter in modern usage, is commonly a fluid coupling that is used to be able to transfer rotating power from a prime mover, for instance an internal combustion engine or an electrical motor, to a rotating driven load. Same as 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 could offer the equivalent of a reduction gear by being able to multiply torque when there is a substantial difference between output and input rotational speed.
The most popular kind of torque converter utilized in automobile transmissions is the fluid coupling kind. During the 1920s there was even the Constantinesco or otherwise known as pendulum-based torque converter. There are various mechanical designs utilized for always variable transmissions which can multiply torque. For example, the Variomatic is a type that has a belt drive and expanding pulleys.
A fluid coupling is a 2 element drive that cannot multiply torque. A torque converter has an extra part that is the stator. This changes the drive's characteristics through occasions of high slippage and generates an increase in torque output.
Within a torque converter, there are at least of three rotating parts: 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 turbine and the impeller so that it could 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 whichever condition and this is where the term stator begins from. In point of fact, the stator is mounted on an overrunning clutch. This design prevents the stator from counter rotating with respect to the prime mover while still allowing forward rotation.
In the three element design there have been modifications that have been incorporated periodically. Where there is higher than normal torque manipulation is considered necessary, changes to the modifications have proven to be worthy. Usually, these alterations have taken the form of multiple stators and turbines. Each and every set has been designed to produce differing amounts of torque multiplication. Several examples comprise the Dynaflow that utilizes a five element converter so as to produce the wide range of torque multiplication considered necessary to propel a heavy vehicle.
Various automobile converters consist of a lock-up clutch to reduce heat and to be able to enhance 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 turbine to the impeller. This causes all power transmission to be mechanical that eliminates losses related with fluid drive.
