Forklift Torque Converter - A torque converter is a fluid coupling which is used to be able to transfer rotating power from a prime mover, that is an electric motor or an internal combustion engine, to a rotating driven load. The torque converter is like a basic fluid coupling to take the place of a mechanical 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 substantial difference between output and input rotational speed.
The most popular type of torque converter used in automobile transmissions is the fluid coupling unit. In the 1920s there was likewise the Constantinesco or also known as pendulum-based torque converter. There are different mechanical designs for continuously changeable transmissions that have the ability to multiply torque. For instance, the Variomatic is a type that has expanding pulleys and a belt drive.
A fluid coupling is a 2 element drive that cannot multiply torque. A torque converter has an added component which is the stator. This changes the drive's characteristics all through occasions of high slippage and generates an increase in torque output.
In a torque converter, there are at least of three rotating components: the turbine, to be able 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. 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 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 enabling forward rotation.
Alterations 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 considered necessary. Most commonly, these modifications have taken the form of many turbines and stators. Every set has been intended to generate differing amounts of torque multiplication. Several examples consist of the Dynaflow which utilizes a five element converter in order 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 improve the cruising power and transmission efficiency, even though it is not strictly component 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.
