1 maj 2020 · A torque converter, which is a hydrodynamic clutch in automatic transmissions, transmits power from the engine shaft to the transmission shaft either by dynamically multiplying the engine...
Typical torque multiplication ranges from 1.8 to 2.5:1 for most automotive applications, up to 5.0:1 or more for static industrial applications or heavy maritime propulsion systems.
Referred to as the mighty one, this torque converter offers a torque multiplication factor of up to 10! This powerful torque converter uses a double-stage turbine, in order to enable the 10-fold torque increase and allows a maximum input speed of 3 600 rpm. The guide vane adjustment is equipped with electric actuators.
For any given output torque demand, for example, for a given vehicle speed on a given grade, slip increases with the loose converter, as shown in Figure 3. This means that loss increases as well (see Figure 4b). In contrast to a clutch, a torque converter can multiply engine torque.
The document summarizes the structure and work principle of a torque converter. It has three main components: an impeller, turbine, and stator. The impeller is connected to the engine and spins fluid outwards, hitting the turbine and making it spin.
The torque converter can either multiply the torque generated by the engine or function as a fluid coupling. The torque converter also serves as the engine flywheel to smooth out engine rotation as its inertia helps to maintain crankshaft rotation between piston power pulses.
6 sie 2018 · The chapter focuses on the mechanism of fluid circulation and torque multiplication, including fluid velocity diagrams, analysis of the angular momentum of automatic transmission fluid (ATF) circulating inside the torque converter, and torque formulations on the torque converter elements.
