Abstract
The utility model discloses a kind of axial seal vibration damper, comprise surge drum, clutch release slave cylinder, guide holder, piston rod, piston, combined seal, combined seal is loaded in the guide holder of surge drum upper end, between the radially flanging of surge drum upper end and combined seal, be provided with axial static seal rubber pad, axial static seal rubber pad is radially being close to guide holder, the described surge drum upper end radially thickness of flanging increases successively from edge to middle part, and the surge drum upper end of axial static seal rubber pad radially inner side radially the internal surface of flanging bend downwards; The utility model the utlity model has the advantage that sealing-strength is high, axial static seal rubber pad is difficult for being extruded, and can meet the needs of large damping force value vibration damper, guarantees sealability.
Description
Technical field
The utility model relates to a kind of axial seal vibration damper.
Background technique
Existing axial seal vibration damper, comprise surge drum, clutch release slave cylinder, guide holder, piston rod, piston, combined seal, combined seal is loaded in the guide holder of surge drum upper end, between the radially flanging of surge drum upper end and combined seal, is provided with axial static seal rubber pad; The radially flanging of surge drum upper end conventionally its thickness successively decreases successively from edge to middle part, causes its sealing-strength less, and difficult satisfied part requires the needs of the vibration damper of large damping force value; And the surge drum upper end radially internal surface of flanging mostly is plane, the axial static seal rubber pad of its inner side is in use easily radially extruded, and affects sealability.
Model utility content
The purpose of this utility model is for prior art above shortcomings, a kind of axial seal vibration damper is provided, it has advantages of that sealing-strength is high, axial static seal rubber pad is difficult for being extruded, and can meet the needs of large damping force value vibration damper, guarantees sealability.
For achieving the above object, axial seal vibration damper of the present utility model, comprise surge drum, clutch release slave cylinder, guide holder, piston rod, piston, combined seal, combined seal is loaded in the guide holder of surge drum upper end, between the radially flanging of surge drum upper end and combined seal, be provided with axial static seal rubber pad, axial static seal rubber pad is radially being close to guide holder, it is characterized in that described surge drum upper end radially the thickness of flanging from edge to middle part, increase successively, and the surge drum upper end of axial static seal rubber pad radially inner side radially the internal surface of flanging bend downwards;
The utility model due to surge drum upper end radially the thickness of flanging from edge to middle part, increase successively, sealing-strength is high, can meet the needs of large damping force value vibration damper; The surge drum upper end of the axial static seal rubber pad radially inner side radially internal surface of flanging bends downwards, forms reducing radially above combined seal, and moving radially of axial static seal rubber pad formed and stopped, avoids being extruded, and guarantees sealability;
As further improvement of the utility model, in described guide holder, be provided with the lining coordinating with piston rod; Lining adopts surface to apply the steel composite material of Babbitt and teflon, can avoid the scratch of piston rod;
In sum, the utlity model has the advantage that sealing-strength is high, axial static seal rubber pad is difficult for being extruded, can meet the needs of large damping force value vibration damper, guarantee sealability, increase the service life.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's plan view.
Fig. 2 is the partial enlarged drawing at I place in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, this axial seal vibration damper, comprise surge drum 1, clutch release slave cylinder 2, guide holder 3, piston rod 4, piston (not shown), combined seal 5, combined seal 5 is loaded in the guide holder 3 of surge drum 1 upper end, between the radially flanging 6 of surge drum 1 upper end and combined seal 5, be provided with axial static seal rubber pad 7, axial static seal rubber pad 7 is radially being close to guide holder 3, the upper end of the described surge drum 1 radially thickness of flanging 6 increases successively from edge to middle part, and the upper end of axial static seal rubber pad 7 radially inner sides radially the internal surface of flanging 6 bend downwards; In described guide holder 3, be provided with the lining 8 coordinating with piston rod 4;
The utility model due to surge drum upper end radially the thickness of flanging 6 from edge to middle part, increase successively, sealing-strength is high, can meet the needs of large damping force value vibration damper; The surge drum upper end of the axial static seal rubber pad 7 radially inner sides radially internal surface of flanging 6 bends downwards, forms reducing radially above combined seal 5, and moving radially of axial static seal rubber pad 7 formed and stopped, avoids being extruded, and guarantees sealability; Lining 8 adopts surface to apply the steel composite material of Babbitt and teflon, can avoid the scratch of piston rod 4.
