Viscous fluid coupling between rotating driveline shafts
Simscape / Driveline / Couplings & Drives
The Torque Converter block models a torque converter. The Torque Converter block has two mechanical rotational conserving ports that are associated with the impeller and turbine, respectively. The block transfers torque and angular velocity between the impeller port I and turbine port T by acting as a lookup table. The block can simulate drive (power flows from I port to T port) and coast (power flows from T port to I port) modes.
When Coast mode modeling is set to
Continuous
:
The impeller shaft must always rotate in a positive direction. Simulation is not valid for < 0.
If you drive the Torque Converter block by using a torque source, such as the Generic Engine block, you must include an inertia in the source to represent the engine, shaft inertia, or other source components. To ensure that the impeller starts by rotating in a positive direction, set the initial speed for this inertia to a positive value.
