Dynamic torque sensing device of thread-on freewheel structure

A dynamic torque sensing device of a thread-on freewheel structure, comprising a thread-on freewheel sensing body, a stationary housing and a sensor, wherein the thread-on freewheel sensing body and the stationary housing are rotatable relative to each other, and the sensor is configured to sense a torque of the thread-on freewheel sensing body;

• and
• wherein the thread-on freewheel sensing body comprises a thread-on freewheel sensing body relatively stationary portion, a thread-on freewheel sensing body relatively rotating portion and a thread-on freewheel sensing body intermediary portion that are integrally formed;
• wherein the thread-on freewheel sensing body relatively stationary portion, the thread-on freewheel sensing body intermediary portion and the thread-on freewheel sensing body relatively rotating portion are sequentially arranged along an axial direction of the thread-on freewheel sensing body, and the thread-on freewheel sensing body intermediary portion is configured to connect the thread-on freewheel sensing body relatively stationary portion to the thread-on freewheel sensing body relatively rotating portion;
• wherein an inner cavity of the thread-on freewheel sensing body relatively stationary portion is provided with a bearing, an inner cavity of the thread-on freewheel sensing body relatively stationary portion is provided with a bearing, and the thread-on freewheel sensing body relatively rotating portion is provided with a thread on its outer surface configured to be connected to an external load.
