Abstract
The utility model discloses a sealing device of an automotive high-pressure shock absorber, which comprises oil seals and a guider, wherein Z-shaped frames that are positioned on the sides of sealing lips of the oil seals are arranged at the joints of the guider and the oil seals; and a sealing lip sheet is fixed at ends of the frames close to a shaft, and is in contact with and sealed with the shaft. In the utility model, a protective device is additionally arranged on the side of the sealing lip of the oil seal to prevent high-pressure oil from impacting the sealing lip of the oil seal, so as to ensure the sealing reliability; and the high-pressure seal problem is solved since the pressure reduction function is fulfilled through the sealing lip.
Description
Technical field
The utility model belongs to reciprocal lip oil seal technique field, especially relates to the high pressure seal that a kind of automobile absorber is used.
Background technique
At present on the sealing system of automobile absorber, sealing mainly is based on oil sealing, along with the requirement to automobile absorber is more and more higher, the damping force of vibration damper inside is also increasing, along with the increase of damping and the increase of speed, the fluid striking velocity and the pressure of vibration damper inside will increase, and this just has higher requirement to the sealability of oil sealing.
High-pressure shock absorber generally is by reducing the lip width with oil sealing at present, increasing waist thickness increases the bearing capacity of oil sealing, if but increase waist thickness simply or reduce the lip width, then can reduce the followability of oil seal lip, thereby influence sealing effect, simultaneously under the condition of identical oil seal lip magnitude of interference, the increase of oil sealing waist thickness, also can cause the too width of cloth of radial force to increase, thereby cause to produce bigger frictional force between lip and the reciprocating shaft, produce following defective: the one, quicken the wearing and tearing of lip and axle, reduce the oil sealing life-span; The 2nd, produce bigger friction Temperature Rise, consume extra power.
Summary of the invention
The purpose of this utility model be to improve the deficiency of prior art and provide a kind of and increase protective equipment, stop in oil sealing sealing lip side high pressure oil to the impact of oil sealing sealing lip, guarantee sealing reliability, realize pressure-reducing function, solve the sealing device for high-pressure shock absorber of automobile of a high pressure sealing difficult problem by the sealing lip sheet.
The purpose of this utility model is achieved in that a kind of sealing device for high-pressure shock absorber of automobile, is made up of oil sealing and guider, is characterized in being provided with at guider and oil sealing binding site the skeleton of the sealing lip oral-lateral that stretches to oil sealing.
In order further to realize the purpose of this utility model, can be that described skeleton is Z-shaped.
In order further to realize the purpose of this utility model, can be to be fixed with the sealing lip sheet near an end of axle at skeleton, the sealing lip sheet touches sealing with being coupling.
In order further to realize the purpose of this utility model, can be respectively to be fixed with a skeleton on upper and lower two surfaces of sealing lip sheet.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is that the binding site at guider and oil sealing is fixed with and stretches to the axial skeleton of sealing, skeleton is fixed with the sealing lip sheet near an end of seal shaft, the sealing lip sheet can contact with the seal shaft extruding, because the damping of automobile absorber is up to several thousand N, when high pressure oil is the ejection of high velocity jet shape during by the gap between seal shaft and the guider, high pressure oil will directly impact on the seal lip of oil sealing, quicken the destruction of seal lip, the utility model mesohigh oil directly impacts on the skeleton, under the prevention of skeleton, the speed of oil reduces, degradation of energy, thereby effectively avoided the impact failure of high pressure oil to the oil sealing lip, the pressure-reducing function of sealing lip sheet excellence can further alleviate the percussion of high pressure oil; Skeleton is Z-shaped, space that can the reasonable use guider, and structure is more reasonable; Upper and lower two surfaces at the sealing lip sheet respectively are fixed with a skeleton, have protected the sealing lip sheet; The utility model has significantly improved the adaptive capacity to high-pressure shock absorber, and the prior art High-pressure oil sealing can only bear≤pressure of 40MPa, the utility model can bear up to 70MPa, even the pressure of 100MPa; Compared with the prior art the utility model has reduced the requirement to oil sealing, make oil sealing design, make simple; Can remove simultaneously the support ring that plays the guiding supporting effect in the prior art, avoid elevated pressure to give birth to " squeezing the crack ", make the simplicity of designization of vibration damper simultaneously.
