Abstract
The utility model discloses an oil seal guider assembly, and belongs to the technical field of automobile parts. The oil seal guider assembly comprises a guider, a first bush, a second bush, a sealing gasket and an O-shaped sealing ring, the first bush and the second bush of the guider are fixed on an inner hole of the guider, the second bush of the guider is mutually compressed with the guider through the sealing gasket and the O-shaped sealing ring, a layer of copper is electroplated on the surface of an inner circle of the first bush of the guider, a movable oil seal and an oil seal compression gasket are further arranged outside the guider, the movable oil seal plays a role in sealing, the oil seal compression gasket is used for fixing the movable oil seal, the double-sealing effect is achieved, the electroplated copper is utilized, the abrasive resistance of a product is increased, the service life of the product is prolonged, the problems that due to abrasion of a sealing part, oil is leaked, and frequent replacement is carried out are solved, and the oil seal guider assembly can be widely applied to the technical field of automobile shock absorbers.
Description
Technical field
The utility model relates to technical field of automobile parts, is specifically related to a kind of oil sealing guider assembly.
Background technique
Automobile is through uneven road surface the time, although the shock-absorbing spring in the shockproof system can filter the vibrations on road surface, but spring self also has to-and-fro motion, and vibration damper is used for suppressing the back and forth jump of this spring, the structure of vibration damper is to insert in the cylinder with the piston rod of piston, be full of oil in the cylinder, throttle orifice is arranged on the piston, so that the oil in two-part space that is separated by piston can complement each other, the working principle of vibration damper is when being subjected to vibrations relative movement to occur between vehicle frame and vehicle bridge or vehicle body and vehicle bridge, piston in the vibration damper moves up and down, fluid in the vibration damper chamber just enters in another chamber through different orifice flows from a chamber repeatedly, the at this moment friction between hole wall and fluid and the intermolecular interior friction of fluid forms damping force to vibrations, making the thump Conversion of Energy is fluid heat energy, is absorbed by vibration damper to be dispersed in the atmosphere again.
Guider is one of strength member in the vibration damper, it plays good guiding and seal action to the motion of piston rod in the vibration damper, guarantee the smoothness of piston in running, and air tight and leakage of oil, as shown in Figure 1, the oil sealing guider assembly of prior art is normally by guider 1, guider the first lining 5, guider the second lining 6, seal washer 4, O RunddichtringO 3, teflin ring 4 and outer O RunddichtringO 2 combine, be fixed on the vibration damper by riveted, piston rod is for a long time to-and-fro motion in the guider assembly, single seal element teflin ring 4 weares and teares easily, so that oil sealing guider assembly can't seal, cause the vibration damper leakage of oil, leak gas, affect the working life of vibration damper.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of good airproof performance, anti abrasive oil sealing guider assembly.
In order to address the above problem, the utility model is achieved by following technological scheme:
Oil sealing guider assembly described in the utility model comprises the guider that is provided with through hole, is installed in guider the second lining in the guider, is installed in guider the first lining that contacts with piston rod in guider the second lining; Be provided with seal arrangement between described guider the second lining and the guider, described guider excircle is provided with external sealed O type circle, and the end of described guider also is provided with elastic material and makes the moving oil sealing that seals and the oil sealing compress gasket that is used for fixing moving oil sealing.
Guider the second lining compresses seal arrangement, plays better seal action, and described seal arrangement comprises gasket seal and the O RunddichtringO that contacts with piston rod, plays the effect of double seal.
For guidance quality and the wearability that improves the guider assembly, guider the first lining and piston rod contact surface have been electroplated layer of copper.
In order to ensure sealing and wearability, the altitude range of described seal washer is 2.5～3.5mm, preferred 3.0mm.
Described oil sealing guider assembly is fixed on the vibration damper by riveted, so the guider excircle is provided with some depressions for the riveted assembling.
Compared with prior art, the beneficial effects of the utility model are:
The utility model has improved guidance quality and the wearability of product, improves the quality of products, and prolonged the working life of vibration damper, has alleviated trouble and the difficulty of user's frequent, has saved cost.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is existing oil sealing guider assembly structure schematic representation;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the device schematic representation of the utility model in vibration damper.
Among the figure: 1-guider, 11-riveted depression, the outer O RunddichtringO of 2-, 3-O RunddichtringO, 4-seal washer, 5-guider the first lining, 6-guider the second lining, 7-moves oil sealing, 8-oil sealing compress gasket, the 9-piston rod, 10-oil sealing guider assembly, 12-fuel tank assembly, 13-riveted point.
Embodiment
Such as Fig. 2～shown in Figure 3, oil sealing guider assembly 10 described in the utility model, comprise guider 1, be installed in guider 1 excircle outer O RunddichtringO 2, be placed on the polytetrafluoroethylene sealing gasket circle 4 that contact with piston rod 9 and the O RunddichtringO 3 that is placed on seal washer 4 cylindrical positions in the guider 1, guider the second lining 6 of being installed in the interior and pressed sealing device of guider 1 be installed in the interior guider that contacts with piston rod 9 the first lining 5 of guider the second lining 6; The face that described guider the first lining 5 contacts with piston rod 9 is electroplated layer of copper, the radial diameter scope of the height of described seal washer 4 and O RunddichtringO 3 is 2.5～3.5mm, preferred 3.0mm, the apical position of described guider 1 also is provided with for the moving oil sealing 7 of sealing and is used for the fixing oil sealing compress gasket 8 that moves oil sealing 7, described moving oil sealing 7 is made by elastic rubber, tight with piston rod 9 Surface Contacts, play good seal action.
Described guider 1 is provided with 6 riveted depressions 11 that are used for device, puts 13 riveteds by the riveted on the surge drum assembly 12 of riveted depression 11 and vibration damper and is fixed together.
The utility model adopts the dual sealing functions of moving oil sealing 7 and seal washer 4, and in guider the first sleeve inner surface plating layer of copper, play good leading role, and increased wearability, improve the quality of product, guaranteed working life of the present utility model.
