Abstract
The utility model discloses a kind of vibration damper sealing system, comprise director assembly and oil sealing, described director assembly at least comprises guider, neck bush, flinger ring, described flinger ring is arranged on the top of neck bush, the utility model provides a kind of sealing system design that can meet vibration damper high and low temperature performance, by the sealability of performance various parts, can ensure to meet under the prerequisite of vibration damper applied at elevated temperature, can meet the low temperature usage requirement of vibration damper, thereby extend the working life of seal and even vibration damper simultaneously.
Description
Technical field
The utility model relates to a kind of vibration damper sealing system, relates in particular to a kind of vibration damper sealing system that need to meet high and low temperature requirement.
Background technique
Vibration damper is one of critical component on vehicle, travelling comfort to car and Security are all most important, vibration damper working principle is that the kinetic energy that motor racing process moderately gusty air is produced is converted into heat energy by the damping of shock absorber fluid generation in damper valve system motion, so the sealing of shock absorber fluid is short most important to vibration damper long service life.Conventionally vibration damper leakage of oil main cause is due to oil seal lip breakage, oil seal lip low temperature loss of seal ability and high temperature ageing.So can vibration damper sealing system normally act under high and low environment, is an important requirement of vibration damper performance.
Along with the continuous appearance of the universal of automobile and extremely cold weather, require now the use minimum temperature of vibration damper generally all lower than-40 DEG C, the rubber material that is generally used for now oil seal for shock damper comprises: NBR, HNBR, FKM, it can meet-40 DEG C-+120 DEG C (45 DEG C-+110 DEG C) respectively,-30 DEG C-+150 DEG C (40 DEG C-+130 DEG C), the usage requirement of-20 DEG C of-+180 DEG C of temperature ranges.But along with the increase of damping force of vibration damper, vibration damper Maximum operating temperature can constantly increase, the wide temperature range of damping work is required to reach the requirement of-40 DEG C-+180 DEG C, also can not find a kind of macromolecular material that can meet this operating conditions at present.So, want to meet the requirement of DEG C-+180 DEG C, vibration damper operating temperature-40, meet again the requirement of sealability simultaneously, must improve the design of the sealing system of vibration damper.
Summary of the invention
The utility model is for above-mentioned the deficiencies in the prior art, a kind of sealing system design that can meet vibration damper high and low temperature performance is provided, by the sealability of performance various parts, can ensure to meet under the prerequisite of vibration damper applied at elevated temperature, can meet the low temperature usage requirement of vibration damper, thereby extend the working life of seal and even vibration damper simultaneously.
The purpose of this utility model is achieved in that a kind of vibration damper sealing system, comprises director assembly and oil sealing, is characterized in that described director assembly at least comprises guider, neck bush, flinger ring, and described flinger ring is arranged on the top of neck bush.
In order further to realize the purpose of this utility model, can be the flinger ring in described director assembly, be by low friction, expand with heat and contract with cold, high-intensity improvement PTFE material forms.
In order further to realize the purpose of this utility model, the cross section that can be described flinger ring is the one in rectangle, fan-shaped, groove-shaped, mazy type.
In order further to realize the purpose of this utility model, can be the groove that described oil seal lip is provided with storing lubricating grease, can reduce frictional force.
In order further to realize the purpose of this utility model, can be that the outer surface of described flinger ring is provided with miniature pressure release, lubricating channels.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is in director assembly, be designed with low temperature flinger ring structure, under cryogenic conditions, can attenuate shock absorber fluid be attached to damper link oil slick thickness, reduce the impact of shock absorber fluid to oil seal lip, reduce the oil sealing pressure of rubber lip, avoid vibration damper leakage of oil.Oil seal lip is designed with antifriction line structure, for oil sealing selflubricating provides condition, has reduced the frictional force of oil sealing; Sealing system has two cover sealings, has the low friction flinger ring and the low friction oil sealing that expand with heat and contract with cold.Flinger ring, be have low friction, expand with heat and contract with cold, high-intensity improvement PTFE material forms, and can reduce shock absorber fluid impact force to oil seal lip under the effect of damping force, reduces the oil film on connecting rod.Shock absorber packing gland, lip is designed with the groove of storing lubricating grease, can storing lubricating grease, reduce the frictional force of oil seal lip and piston rod.
Action principle of the present utility model is as follows:
1) under cryogenic conditions, shock absorber fluid fluid viscosity improves, the adhesion of bar is increased, and meanwhile, vibration damper damping meeting increases, the impact of oil seal lip is increased, and design has increased the high-intensity PTFE flinger ring with the performance of expanding with heat and contract with cold, under cryogenic conditions, the enclasping force of piston rod is increased, of course, attenuate shock absorber fluid adheres to thickness, the impact force of reduction vibration damper fluid to oil seal lip of piston rod.
2) design by flinger ring, can better meet the cryogenic property requirement of vibration damper, in the design of rubber oil sea, can select heat-resisting quantity can better rubber material to meet the high temperature requirement of vibration damper.
On the basis of technique scheme, the utility model can also improve the cross section structure of flinger ring, can meet the seal request of different damping power, according to the external structure of flinger ring, designs corresponding oil circuit, plays decompression, pressure release, lubricated effect.
By adjusting the length of neck bush, reducing the impact force of shock absorber fluid to oil seal lip with the gap of piston rod.
Be provided with the groove of storing lubricating grease at the lip of oil sealing, can store lubricant oil/fat, play self-lubricating function, reduce the frictional force between oil sealing and connecting rod.
Adopt the utility model scheme, can meet vibration damper the operating temperature requirement of-40 DEG C-180 DEG C.
