| Effect | The function of the torque converter is to transfer power by means of the high-speed movement of the liquid. It has the function of stepless speed change and torque change, and can change the running direction of the locomotive without stopping. Widely used as a transmission device between various power engines and working machines. For example, it is used as a transmission device for road transport vehicles and railway transport vehicles. In addition, it is also used in construction machinery, mining machinery and large ships |
| Structure | The hydraulic torque converter is composed of a pump wheel, a turbine and a guide wheel. The pump wheel is connected with the drive shaft, and the mechanical energy input by the drive shaft can be converted into the kinetic energy and pressure head of the liquid by the action of centrifugal force for the turbine to do work. The turbine is connected to the driven shaft, and the kinetic energy of the liquid and the energy contained in the indenter are output by the driven shaft.
The operating characteristic of the torque converter is that the speed and torque at the input end are basically constant; Or although there are changes, but the change is small. The speed and torque at the output end can be greater than, equal to or less than the speed and torque at the input end, and the output speed and output torque can be adjusted automatically and continuously with the size of the driving machine load |
Torque converter is a non-rigid torque converter with liquid as the working medium, and is one of the forms of hydraulic transmission. The picture shows the hydraulic torque converter, which has a closed working chamber, the liquid circulates in the chamber, wherein the pump wheel, turbine and guide wheel are connected with the input shaft, the output shaft and the housing respectively. When the power engine (internal combustion engine, electric motor, etc.) drives the input shaft to rotate, the liquid comes out from the centrifugal pump in turn, passes through the turbine, the guide wheel and then returns to the pump wheel, circulating and flowing again and again. The pump wheel transfers the mechanical energy of the input shaft to the liquid. The high-speed liquid spins the turbine, sending energy to the output shaft.
The torque converter transfers torque by the change of dynamic moment generated by the interaction between the liquid and the blade. The main feature of the torque converter is that it has a fixed guide wheel which is different from the hydraulic coupler. The guiding wheel of the liquid diversion effect makes the output torque of the hydraulic torque converter higher or lower than the input torque, so it is called the torque converter. The ratio of output torque and input torque is called the torque coefficient, and the zero speed torque coefficient is usually about 2~6 when the output speed is zero. The torque coefficient decreases with the increase of output speed. The input shaft of the torque converter is connected with the output shaft by the liquid, and there is no rigid connection between the working members. The characteristics of the torque converter are: can eliminate shock and vibration, overload protection performance and good starting performance; The speed of the output shaft can be greater than or less than the speed of the input shaft, and the speed difference between the two axes varies with the size of the transmitted torque; It has good automatic speed change performance, the output speed automatically decreases when the load increases, and automatically rises otherwise; Ensure that the engine has a stable working area, and the transient change of load will not be reflected to the engine.
The efficiency of the torque converter is high near the rated working condition, and the maximum efficiency is 85%~92%. The impeller is the core of the torque converter. Its type, layout position and blade shape have a decisive effect on the performance of the torque converter. Some torque converters have more than two turbines, guides or pump wheels to achieve different performance. The most common are forward turning (output shaft and input shaft turn in the same direction), single-stage (only one turbine) torque converters. Both torque converter and coupler performance characteristics are called comprehensive torque converter, such as the guide wheel can be fixed, can also be rotated with the pump wheel hydraulic torque converter. In order to make the torque converter work normally, avoid cavitation and ensure heat dissipation, auxiliary oil supply system and cooling system with certain oil supply pressure are needed.
