Abstract
The invention discloses a stable-type damping device, which comprises at least two magnets. Opposite magnetic poles of the magnets are adjacent, the magnets are hinged on a cross shear-type expansion bracket, retaining-and-guiding inner sleeves are sleeved outside the magnets, upper end seats and lower end seats are disposed at both ends of the retaining-and-guiding inner sleeves respectively and connected with both ends of the cross shear-type expansion frame respectively, and damping springs are installed between the upper end seats and the lower end seats. Since opposite magnetic poles of adjacent magnets are arranged oppositely, the closer the distance, the greater the attraction; when severe vibration occurs, the damping springs are compressed and deformed greatly, the elasticity of the damping springs increases linearly with the deformation; when the deformation of the damping springs increases, the distance between adjacent magnets decreases, the attraction increases geometrically, a part of increased elasticity is offset, in other words, impact force to car frames is decreased. By the stable-type damping device, stable damping can be realized when the elasticity of dampers can be kept changing mildly and nonlinearly within a bigger deformation range.
