1. A friction disk comprising an elastic component and a plurality of friction monomers;
wherein:
the plurality of friction monomers are distributed in an annular array and enclosed to form a central space, each of the plurality of friction monomers being movable towards or away from the central space along a radial direction of the annular array, the elastic component being connected with the plurality of friction monomers, respectively, and the elastic component being configured with a pre-tightening force to make the plurality of friction monomers close to the central space;
the elastic component comprises:
a fixed frame located in the central space, the fixed frame forming a space within for adapting a shaft sleeve; and
a second tension spring group connected between the plurality of friction monomers and the fixed frame, the second tension spring group comprising at least one second tension spring; and
the elastic component further comprises at least one guide element having an end fixedly connected to the fixed frame, the at least one guide element extending along the radial direction of the annular array, and a chute slidably matched with the at least one guide element being arranged on one side of at least one friction monomer that faces the central space.
