Abstract
The utility model relates to a vibration damper with fastening edges, which comprises an external cylinder of the vibration damper, an inner cylinder, a guider, a working cylinder, a piston rod assembly, a compression valve base and an oil storage cylinder base. The utility model is characterized in that the upper end of the external cylinder of the vibration damper is inwards provided with fastening edges along the circumference, and an oil sealing framework and oil seal are arranged between the bottom plane of the fastening edges and the guider. The utility model benefits for maintenance of stable pre-tightening force of the structure of the vibration damper, and the pre-tightening force is very important to the normal work of the vibration damper; the utility model has the advantages of simple structure, convenient operation, higher efficiency and low cost, and the utility model is favorable for mass production in production lines; the sealing performance of the oil seal is favorable, the performance is stable, and the service life is long; the utility model is especially suitable for sliding column guide barrel type vibration dampers. The method of the utility model is suitable for non-guide type vibration dampers and also suitable for the sealing method of the external cylinders of thin wall vibration dampers.
Description
The utility model relates to vehicle shock absorber, particularly a kind of vibration damper of detaining the limit that has.
The normal employing of the oil-sealing arrangement of traditional vibration damper upper end is threaded, and part is many, just can reach as needs oil seal cover and O type circle and seal purpose.Its manufacture cost height, labor strength is big during assembling, and efficient is low, is unfavorable for mass production, and poor reliability, is easy to generate loosening in the use.
The purpose of this utility model provide a kind of simple in structure, sealability is excellent has the vibration damper of detaining the limit.
The utility model design have the vibration damper of detain limit comprise the vibration damper urceolus, and urceolus concentric and upper edge be lower than on the inner core, inner core upper edge of urceolus and be provided with the outer clutch release slave cylinder of guider, inner core between the urceolus, along being the compression valve base on the urceolus bottom surface of the up and down piston-rod assembly in axle center, inner core lower end, outer tube bottom is provided with the oil storage cylinder base, be characterized in being provided with oil tight skeleton and oil sealing between the bottom plane on described button limit and the guider at the circumferential internal buckle edge of vibration damper urceolus upper end edge.
Wherein, described oil sealing cylindrical place is provided with the ring-shaped rubber sealing strip that is combined into one with it.
The vibration damper of detain limit that has of the utility model design has the following advantages: help the stable pretightening force of damper structure maintenance, and this pretightening force is very important to the proper functioning of vibration damper; Simple in structure, easy to operate, efficient is higher, and cost is low, helps producing in enormous quantities on the production line; The good seal performance of oil sealing, and stable performance, service time is long; Be specially adapted to traveller guiding type telescopic shock absorber.This method is suitable for non-guiding type vibration damper, and is suitable for the mouth-sealing method of thin-walled class vibration damper urceolus.
Further describe the utility model below in conjunction with drawings and Examples
Accompanying drawing 1 is an agent structure schematic representation of the present utility model;
Accompanying drawing 2 is a partial enlarged drawing;
Accompanying drawing 3 is a partial top view.
Wherein, label 1 is an oil sealing, and 2 is the vibration damper urceolus, and 3 is oil tight skeleton, and 4 is guider, and 5 is the vibration damper inner core, and 6 is plug cock bar assembly, and 7 is piston, and 8 is clutch release slave cylinder, and 9 is annular sealing strip.
As shown in Figure 1 have a vibration damper of detaining the limit, it comprises vibration damper urceolus 2, be lower than the inner core 5 of urceolus with urceolus concentric and upper edge, be provided with guider 4 on the inner core upper edge and between the urceolus, the clutch release slave cylinder 8 that inner core is outer, the up and down piston-rod assembly 6 along the axle center, be the compression valve base on the urceolus bottom surface of inner core lower end, outer tube bottom is provided with the oil storage cylinder base, be characterized at the circumferential internal buckle edge of vibration damper urceolus upper end edge, be provided with oil tight skeleton 3 and oil sealing 1 between the bottom plane on described button limit and the guider, described oil sealing cylindrical place is provided with the ring-shaped rubber sealing strip 9 that is combined into one with it.
This vibration damper is when sealing, use a roller will have the thin property wall vibration damper urceolus epimere barrel of relative rotary motion inwardly to push roll extrusion with it, form a kind of integral body to the internal buckle edge structure, compress vibration damper inner bodies such as shock absorber packing gland and guider simultaneously by this button limit, thereby reach the purpose that vibration damper seals.At this moment, oil sealing moves down, and the oil sealing bottom is subjected to the constraint of parts such as guider, clutch release slave cylinder, compression valve seat, oil storage cylinder base and vibration damper urceolus, with isolating fully between vibration damper internal structure and the extraneous medium, has guaranteed the vibration damper static sealing; When oil tight skeleton was close to the guide holder upper-end surface, the stressed increase of guider also passed to clutch release slave cylinder, the parts such as compression valve seat, oil storage cylinder base and vibration damper urceolus etc. of its underpart with this power, until the upper-end surface of support fixture.The clutch release slave cylinder barrel produces resiliently deformable owing to being under pressure under this support and force mechanism, the inner correlated parts of oil sealing, clutch release slave cylinder and vibration damper is subjected to pressure stress all the time, thereby guaranteed the sealability of shock absorber packing gland, guaranteed that inner each part of vibration damper is when automobile running, the unlikely generation changing of the relative positions even be subjected to bigger lateral forces, thus the vibration damper that has this structure can be worked steadily in the long term.
Claims (2)
1, a kind of vibration damper of detaining the limit that has, comprise the vibration damper urceolus, and urceolus concentric and upper edge be lower than on the inner core, inner core upper edge of urceolus and be provided with the outer clutch release slave cylinder of guider, inner core between the urceolus, along being the compression valve base on the urceolus bottom surface of the up and down piston-rod assembly in axle center, inner core lower end, outer tube bottom is provided with the oil storage cylinder base, it is characterized in that being provided with oil tight skeleton and oil sealing between the bottom plane on described button limit and the guider at the circumferential internal buckle edge of vibration damper urceolus upper end edge.
2, vibration damper as claimed in claim 1 is characterized in that described oil sealing cylindrical place is provided with the ring-shaped rubber sealing strip that is combined into one with it.
