Modifications to the basic three element design have been periodically incorporated, especially in applications where higher than normal torque multiplication is required. In practice, however, the stator is mounted on an overrunning clutch, which prevents the stator from counter-rotating with respect to the prime mover but allows forward rotation. The classic torque converter design dictates that the stator be prevented from rotating under any condition, hence the term stator. In a torque converter there are at least three rotating elements: the impeller, which is mechanically driven by the prime mover the turbine, which drives the load and the stator, which is interposed between the impeller and turbine so that it can alter oil flow returning from the turbine to the impeller. The equation expands to include the fifth power of radius as a result, torque converter properties are very dependent on the size of the device.Ī fluid coupling is a two-element drive that is incapable of multiplying torque, while a torque converter has at least one extra element-the stator-which alters the drive's characteristics during periods of high slippage, producing an increase in output torque. Torque converter equations of motion are governed by Leonhard Euler's eighteenth century turbomachine equation: Industrial power transmission such as conveyor drives, almost all modern forklifts, winches, drilling rigs, construction equipment, and railway locomotives.įunction Theory of operation.Forwarders and other heavy duty vehicles.Automatic transmissions on automobiles, such as cars, buses, and on/off highway trucks.Variomatic with expanding pulleys and a belt drive. They include the pendulum-based Constantinesco torque converter, the Lambert friction gearing disk drive transmission and the There are also mechanical designs for continuously variable transmissions and these also have the ability to multiply torque. There are also hydrostatic systems which are widely used in small machines such as compact excavators. This is a feature beyond the simple fluid coupling, which can match rotational speed but does not multiply torque and thus reduces power.īy far the most common form of torque converter in automobile transmissions is the hydrokinetic device described in this article. The main characteristic of a torque converter is its ability to increase torque when the output rotational speed is so low, it allows the fluid, coming off the curved vanes of the turbine to be deflected off the stator while it is locked against its one-way clutch, thus providing the equivalent of a reduction gear. The equivalent location in a manual transmission would be the mechanical clutch. It is usually located between the engine's flexplate and the transmission. In a vehicle with an automatic transmission, the torque converter connects the power source to the load. So far we have seen only the oem scanner can do this.A torque converter is a type of fluid coupling that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. Perform adaption procedure with diagnostic tool. Use the proper transmission fluid MB 236.14. In general at 100.000 KM or more the valve body should be rebuild. Pessure regulator valve, TCC/valve and lubrication valve are known for wear. Make sure the transmission and valve body are in good condition.
