可変減衰ダンパ

Japanese Patent JP6481763

B2

The present disclosure discloses a variable damping shock absorber comprising 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 into through the opening and being slideably provided in an axial direction inside the sleeve, at least 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, the 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. Specifically, each set of the friction plates has a same thickness in a radial direction of the sleeve and has a different friction coefficient of a surface of one side which is in contact with the outer wall of the piston rod, and the friction coefficient decreases from the closed end to the open end of the sleeve. Alternately, each set of friction plates are of a same material, and a thickness of the friction plates in a radial direction of the sleeve is different, and the thickness of each set of friction plates decreases from the closed end to the open end of the sleeve. The shock absorber of the present disclosure is simple and practical, and the cost is low, and the structure can ensure that the damping force is variable under different load and the rotational speed conditions.
