Embodiment Construction
[0023] The anti-leakage device of a kind of fluid damper provided by the present invention has the structure as follows: Figure 1 to Figure 3 As shown: its structure includes a first sealing ring 1 and a second sealing ring 2, an outer steel cylinder 3, a viscoelastic material 4, an inner steel cylinder 5, a piston rod 6 and a damper outer cylinder 9. The device also includes The thickness of the elastic material is appropriately increased to the steel cylinder 11 .
[0024] In the embodiment of the present invention, the first sealing ring 1 and the second sealing ring 2 are sealing rings formed of rubber materials, which are used to prevent the liquid in the fluid damper from leaking from the anti-leakage device of the present invention and the damper. Outflow from the gap between the outer cylinder and the piston rod.
[0025] The outer steel cylinder 3 and the inner steel cylinder 5 are steel cylinders made by a mould, and the shape of the mold will be customized accordi...

The invention relates to a leakage prevention device of a fluid damper. The leakage prevention device comprises a first seal ring, a second seal ring, an outer steel cylinder, a viscoelastic material, an inner steel cylinder, a piston rod and a damper outer barrel. A sealing device of the fluid damper is designed by use of the characteristics of good extensibility, high deformability, excellent aging resistance and the like of the viscoelastic material, so as to prevent liquid in the damper from leaking. A joint of a cylinder tube and a piston of the damper is sulphidized and glued by use of the viscoelastic material, relative movement can be generated between the piston rod and the cylinder tube by use of the excellent deformability of the viscoelastic material, and furthermore, the viscoelastic material is tightly glued together with the cylinder tube and the piston rod, so that the liquid in the cylinder tube can not leak out from the joint of the piston rod and the cylinder tube. Compared with a traditional fluid damper, the leakage prevention device is capable of thoroughly preventing the liquid in the damper from leaking, and thus greatly prolonging the service life of the damper.
Description
technical field [0001] The invention relates to an anti-leakage device of a fluid damper. The damper manufactured by adopting this technology can be used in the fields of civil engineering, automobile engineering, mechanical engineering and the like. Background technique [0002] Fluid dampers (including viscous fluid dampers, magnetorheological fluid dampers, magnetorheological grease dampers, etc.) are widely used vibration reduction devices. At present, sealing rings are often used between the piston rod of the damper and the outer steel cylinder to seal the liquid in the cavity. Due to problems such as easy aging of the sealing rings, the sealing effect has not been very good. Especially for the magnetorheological fluid damper, when the relative sliding occurs between the piston rod and the steel cylinder, the carbonyl iron powder particles in the magnetorheological fluid are adsorbed on the wall of the piston rod and embedded in the rubber sealing ring. The position ru...
