Forklift Torque Converter - A torque converter in modern usage, is commonly a fluid coupling which is utilized 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. Like 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 can provide the equivalent of a reduction gear by being able to multiply torque when there is a significant difference between output and input rotational speed.
The most popular kind of torque converter utilized in automobile transmissions is the fluid coupling unit. During the 1920s there was also the Constantinesco or otherwise known as pendulum-based torque converter. There are various mechanical designs for continuously variable transmissions that can multiply torque. Like for instance, the Variomatic is one kind that has expanding pulleys and a belt drive.
A fluid coupling is a 2 element drive that is incapable of multiplying torque. A torque converter has an extra element which is the stator. This alters the drive's characteristics all through times of high slippage and generates an increase in torque output.
In a torque converter, there are a minimum of three rotating parts: the turbine, in order 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. Traditionally, the design of the torque converter dictates that the stator be stopped from rotating under any situation and this is where the term stator starts from. In point of fact, the stator is mounted on an overrunning clutch. This particular 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 alterations 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. Usually, these adjustments have taken the form of many turbines and stators. Each set has been intended to produce differing amounts of torque multiplication. Various examples comprise the Dynaflow that makes use of a five element converter so as to produce the wide range of torque multiplication needed to propel a heavy vehicle.
While it is not strictly a part of classic torque converter design, various automotive converters include a lock-up clutch so as to lessen heat and in order to enhance cruising power transmission efficiency. The application of the clutch locks the impeller to the turbine. This causes all power transmission to be mechanical that eliminates losses associated with fluid drive.
