One Way Rotational Clutch
Parallel connection of freewheel and clutch
Description
Connections
Parameters
Modelica Standard Library
The One Way Rotational Clutch (or One Way Clutch) component models a one-way clutch, which is a clutch connected in parallel to a free wheel. This special element is provided because such a parallel connection introduces an ambiguity to the model (the constraint torques are not uniquely defined when both elements are stuck) and this element resolves it by introducing one constraint torque instead of two. See the Clutch model for the basic model description.
