Variable preload-rigidity self-resetting rotating joint
The invention relates to a variable-preload-rigidity self-resetting rotating joint, which comprises a bracket; the rotating frame is rotationally connected with the bracket through a rotating shaft, and the rotating shaft is further provided with a gear coaxially connected with the rotating shaft; the two cover plates are respectively positioned above and below the rotating shaft, and racks meshed with the gears are also arranged on the cover plates; and two ends of the self-resetting device are respectively connected with the bracket and the cover plate. The problems that an existing self-resetting joint cannot achieve adjustable resetting force, or due to the fact that the rotating angle of the joint is small, the energy dissipation capacity and the resetting capacity are insufficient, or variable rigidity cannot be achieved can be solved.
本发明涉及一种变预载‑刚度自复位旋转节点，包括：托架；通过转动轴与所述托架转动连接的转动架，在所述转动轴上还与其同轴连接的齿轮；分别位于所述转动轴上下方的两块盖板，在盖板上还设有与所述齿轮啮合的齿条；以及具有可变刚度的自复位装置，其两端分别连接所述托架与盖板。本发明可解决现有自复位节点无法实现可调节的复位力，或由于节点转动角度较小，存在耗能能力和复位能力不足，或无法实现变刚度等问题。
