  • Patent number: 10288140
    Abstract: A variable damping shock absorber has a sleeve and a piston rod, one end of the sleeve being an opening and the other end being closed, one end of the piston rod being inserted through the opening and slidable in an axial direction inside the sleeve. Two sets of friction plates are arranged in the axial direction between an inner wall of the sleeve and an outer wall of the piston rod. A friction plate is fixed in the axial direction with the inner wall of the sleeve, and a sliding friction force between each friction plate set and the outer wall of the piston rod gradually decreases from the closed end to the opening end of the sleeve. The structure can ensure that the damping force is variable under different load and rotational speed conditions.

  • Publication number: 20180142754
    Abstract: A variable damping shock absorber includes a housing and a piston rod capable of sliding along an inner wall of the housing. A first damping unit is fixedly arranged on the piston rod, which moves with the piston rod and generates frictional force with the inner wall of the housing. An accommodating space is formed between a part of the piston rod and the inner wall of the housing. A second damping unit matched with the inner wall of the housing is arranged in the accommodating space. The second damping unit vertically moves along the inner wall of the housing, and generates frictional force with the inner wall of the housing.
