Abstract

See full text

A power strut includes anisotropic damping device that provides different frictional torque on a rotatable member in response to rotation in opposite rotational directions. The anisotropic damping device includes a shell, the rotatable member, and a torsion spring. The shell includes a through hole, and the rotatable member extends through the through hole and is rotatably connected to the shell. The torsion spring is sleeved on the rotatable member and is in interference fit with the rotatable member, and the torsion spring is provided with a first leg fixedly connected to the shell. The rotatable member may include a shaft sleeve fixed to a rotating shaft, with the torsion spring in interference fit with the shaft sleeve.
