Abstract
The utility model relates to an improvement of a compressing valve structure of a shock absorber. A valve seat and a compensating valve plate, a compensating valve spring which are arranged above the valve seat and a compressing throttle valve plate, a compressing valve plate which are arranged below the valve seat are connected together by a valve rod. The utility model is characterized in that a washer is arranged at the outside of the compressing valve plate; the connection of the valve system part is a fixing connection structure of the valve rod and rotating rivets. The middle of the working face of the washer is provided with a boss, a plane under the boss presents an inclined plane which is high inside and low outside. An inner valve line of the valve seat is lower than an outer valve line of the valve seat. The utility model has the advantage of simple and reasonable structure, as the riveting deformation of the valve rod makes a firm connection among the valve system parts, effectively preventing the early failure of the valve system which is caused by the loose connection.
Description
Technical field
The utility model relates to a kind of automobile absorber, especially relates to a kind of improvement of shock absorber compression valve structure.
Background technique
The shock absorber compression valve sub-assembly is an important component part in the vibration damper assembly, it mainly realizes the generation of vibration damper compression damping power, to alleviate the vibration that vehicle produces when uneven road surface travels, guarantee vehicle smoothness under steam and occupant's travelling comfort.The compression valve of prior art, its valve rod adopts screw thread to tighten connection, its performance is subjected to the influence of the screw thread width of cloth, and to the requirement on machining accuracy height of part, compressive force instability when producing in batches, product in use is subjected to the hydraulic shock of reciprocal load, and screw thread is easy to generate loosening, thereby causes the early failue of whole vibration damper.
Summary of the invention
The utility model mainly is to solve existing in prior technology: to the requirement on machining accuracy height of part, and compressive force instability when producing in batches, product in use easily produces loosening, and causes the deficiency of the early failue of whole vibration damper.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: valve rod is linked together valve seat and top compensation valve block, recuperation valve spring and following compression throttling valve block, compression valve block, it is characterized in that: also have packing ring in compression valve block outside, valve is that the part connection is the fixed connection structure that valve rod revolves riveting.
As preferably, in the middle of the working surface of packing ring boss is arranged, the face under the boss is low inside and high outside inclined-plane.
As preferably, the internal valve line of valve seat is lower than outer valve line.
Therefore, the utility model is simple and reasonable for structure, is that part is connected firmly because the riveted joint of valve rod distortion makes valve, has prevented that effectively because of connecting the loosening valve that produces be early failue, has improved the working life of product; Setting up of change by cutting down line and packing ring played good effect to sealing and the liquid stream stability that improves product.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is that the valve body of Fig. 1 is faced enlarged view;
Accompanying drawing 3 is packing ring cutaway view Amplified images of Fig. 1.
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is done further
Specific description.
Embodiment: as Figure 1-3, valve rod 1 is taked valve seat 4 and top compensation valve block 3, recuperation valve spring 2 and following compression throttling valve block 5, compression valve block 6 packing rings 7 to revolve the riveting structure and is fixed together, because added pressure when revolving riveting is connected firmly valve rod 1 and the part that links together; The internal valve line 9 of valve seat 4 is lower than outer valve line 10, has improved the sealing of compression valve; Packing ring 7 adopts cold-extrusion technology, and packing ring 7 is a boss 11 with the surface of contact of compression valve block 6, and the plane under the boss is low inside and high outside inclined-plane 12, has controlled the stability that liquid stream flows effectively.
The utility model is applicable in the front and back vibration damper product of multiple car, owing to take above-mentioned effective measures, is installed in this product in the various vibration dampers, reaches 160,000 kilometers by what the road examination had, and using effect is good.
