Among them, the training process parameters include the parameters transmitted back by the first tension sensor 191 and the second tension sensor 192.

[0078] The process of adjusting the resistance adjusting member 2 of the present invention is as follows:

[0079] The controller 4 controls the operation of the servo electric cylinder 24. When the servo electric cylinder 24 operates, it drives the first friction disk 26 to slide on the sliding rod 251, thereby adjusting the pressure between the first friction disk 26 and the second friction disk 27. When the pressure between the first friction disk 26 and the second friction disk 27 changes, the torque value when the first friction disk 26 slips relative to the second friction disk 27 changes, and the rotational resistance of the cable drum 25 that rotates synchronously with the first friction disk 26 changes.

[0080] It should be noted that when the operating mode of the motor 3 is the torque mode, the torque value when controlling the first friction disk 26 to slip relative to the second friction disk 27 is less than the current output torque value of the motor 3, so as to protect the motor 3 by the resistance adjusting member 2.

[0081] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0082] The embodiments described above are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
