DYNAMIC TORQUE SENSING DEVICE OF THREAD-ON FREEWHEEL STRUCTURE

A dynamic torque sensing device of a thread-on freewheel structure includes a thread-on freewheel sensing body (1), a fixed housing (2) and a sensor (12), where the thread-on freewheel sensing body and the fixed housing are rotatable relative to each other, and the sensor is configured to sense a torque of the thread-on freewheel sensing body; and the thread-on freewheel sensing body includes a thread-on freewheel sensing body relative fixing portion (101), a thread-on freewheel sensing body relative rotating portion (102) and a thread-on freewheel sensing body transition portion (103); where the thread-on freewheel sensing body relative fixing portion, the thread-on freewheel sensing body transition portion and the thread-on freewheel sensing body relative rotating portion are sequentially arranged along an axial direction of the thread-on freewheel sensing body, and the thread-on freewheel sensing body transition portion is configured to connect the thread-on freewheel sensing body relative fixing portion to the thread-on freewheel sensing body relative rotating portion.
