Abstract: A dynamic torque sensing device of a thread-on freewheel structure includes a thread-on freewheel sensing body (1), a stationary housing (2) and a sensor (12). 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. The thread-on freewheel sensing body includes a thread-on freewheel sensing body relatively stationary portion (101), a thread-on freewheel sensing body relatively rotating portion (102) and a thread-on freewheel sensing body intermediary portion (103). 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. 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.

Abstract: Provided is a freehub torque and speed sensing device, including a freehub, a dynamic assembly and a static assembly. The freehub includes a freehub body (2) and a freehub fixing housing (1) sleeved on an outer side of the freehub body (2). A load connection portion (204) is disposed at one end of the freehub body (2). A torque sensing deformation unit (203) is disposed at the freehub body (2) adjacent to the load connection portion (204) and includes at least one sensor. The dynamic assembly rotates with the freehub body (2). The static assembly is fixedly connected to an external fixing structure body and includes a primary control unit. The dynamic assembly includes a secondary control unit electrically connected to the sensor. A torque signal is transmitted between the primary control unit and the secondary control unit in a wireless manner, and the primary control unit supplies power to the secondary control unit in the wireless manner. In this manner, the whole vehicle assembly is more convenient and safer, and the signal stability is high.
