Description
Technical field
The utility model relates to a kind of valve seat, particularly relates to a kind of vehicle shock absorber foot valve seat and vehicle shock absorber.
Background technique
In the design process of shock absorber for vehicle, the function of foot valve seat is: 1. to coordinate with bottom valve bar as the basic part of sub assembly of bottom valve and form sub assembly of bottom valve; 2. coordinate with clutch release slave cylinder and locate and support works cylinder; 3. coordinate with bottom, axial limiting and radial location are carried out to the internal damping device of vibration damper.
Foot valve seat as one of vibration damper key components and parts, the defect such as its appearance requirement must not have any breakage, crackle, collide with.In the assembly process of vibration damper, the most easily occur that foot valve seat collides with, damaged operation is the operation that clutch release slave cylinder sub-assembly puts into surge drum.In this operation, surge drum is vertical placement, to manually clutch release slave cylinder is put into from surge drum oral area, due to internal diameter and the clutch release slave cylinder crest clearance comparatively large (general monolateral gap is 3mm) of surge drum, the process radial direction that clutch release slave cylinder is putting into surge drum does not position, and causes clutch release slave cylinder easily to tilt to surge drum internal diameter.After hand unclamps, clutch release slave cylinder sub-assembly falls in freely falling body mode, and when falling to bottom surge drum, foot valve seat accurately cannot contact with bottom and coordinate.
When the indivedual pawl of foot valve seat and bottom instantaneous touch, the suffered impact force in local increases, the defect such as cause foot valve seat claw, bottom local to collide with, to chew, and even occurs foot valve seat claw phenomenon of rupture.After the component assembling of defect, foot valve seat and bottom are localized contact, increase localized contact stress after following process.In the process of moving, vibration damper affects by alternate load vehicle, and under alternating stress impact, micro-loosening phenomenon easily appears in foot valve seat and bottom localized contact place, causes and occurs Abnormal Sound Trouble.
Therefore, the direction becoming these those skilled in the art and make great efforts how is solved the problems of the technologies described above.
Model utility content
The purpose of this utility model is just to provide a kind of novel bottom valve seat and vehicle shock absorber, can solve above-mentioned the deficiencies in the prior art part completely.
The purpose of this utility model is realized by following technical proposals:
A kind of novel bottom valve seat, comprises foot valve seat body, it is characterized in that: be evenly arranged at least three flanges along foot valve seat body outer wall circumference.
Further, described flange arrangement is circumferentially same what be the center of circle with foot valve seat body central.
Further, the end of described flange is the arc surface mated with above-mentioned circumference.
A kind of vehicle shock absorber with above-mentioned foot valve seat, comprise foot valve seat, bottom valve bar, bottom, clutch release slave cylinder and surge drum, described bottom is fixed on surge drum inner bottom part, foot valve seat is placed in surge drum and coordinates with bottom, foot valve seat center hole coordinates bottom valve bar, clutch release slave cylinder is arranged on foot valve seat end face, it is characterized in that: the outer wall of described foot valve seat is circumferentially evenly arranged at least three flanges, described flange arrangement with concentric circumferentially same of foot valve seat center hole, the flange end on described foot valve seat and the gap between surge drum inwall are 0.5 ~ 0.8mm.
Compared with prior art, the beneficial effects of the utility model are: structure is simple, reasonable in design, reduce the chance of colliding with, chewing of foot valve seat in assembly process, increase the area of contact of the rear foot valve seat of assembling and bottom, reduce the contact stress of foot valve seat and bottom, improve operational safety and the stability of vibration damper, extend the working life of vibration damper, effectively reduce the rate of fault after sale of vibration damper.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model vehicle shock absorber;
Fig. 2 is the structural representation of the foot valve seat in Fig. 1.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As depicted in figs. 1 and 2, a kind of novel bottom valve seat, comprises foot valve seat body 1, is evenly arranged four flanges 2 along foot valve seat body 1 outer wall circumference.
Described flange 2 is arranged in foot valve seat body central, and to be the center of circle circumferentially same, and the end of described flange 2 is the arc surface mated with above-mentioned circumference.
See Fig. 1, a kind of vehicle shock absorber with above-mentioned foot valve seat, comprise foot valve seat 101, bottom valve bar 102, bottom 103, clutch release slave cylinder 104 and surge drum 105, described bottom 103 is fixed on surge drum 105 inner bottom part, foot valve seat 101 is placed in surge drum 105 and coordinates with bottom 103, foot valve seat center hole coordinates bottom valve bar 102, clutch release slave cylinder 104 is arranged on foot valve seat 101 end face, the outer wall of described foot valve seat 101 is circumferentially evenly arranged four flanges 2, described flange 2 is arranged in concentric circumferentially same with foot valve seat center hole, and the end of flange 2 is the arc surface mated with this circumference.Flange 2 end on described foot valve seat 101 and the gap A between surge drum 105 inwall are 0.5 ~ 0.8mm.
Localized contact phenomenon is there is in this foot valve seat structure defect and the foot valve seat 101 such as can avoid occurring when putting into surge drum colliding with, chew with bottom 103.Above-mentioned foot valve seat 101 outside dimension and surge drum 105 internal diameter size gap A are 0.5 ~ 0.8mm, because this reducing the gap between foot valve seat 101 outer wall and surge drum 105 inwall, thus ensure that the several pawls on foot valve seat 101 contact with bottom simultaneously, increase its area of contact, reduce foot valve seat 101 and bottom 103 contact stress, reduce vibration damper foot valve seat 101 and bottom 103 surface of contact in high strength, alternate load using process to be out of shape, improve the working life of vibration damper.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
