Abstract
The utility model discloses a bottom valve assembly of a shock absorber, which comprises a compression valve limiting device (9), a valve block group (8), a bottom valve (7), a circulation slice (6), a spring piece (5), a gasket (4) and a compensating valve limiting device (3) which are sequentially sleeved on a valve rod (1). An axial limiting structure is arranged at the tail end of the valve rod (1), the axial limiting structure of the valve rod (1) relates to the structure that the end of the valve rod (1) extends out of a hole of the compression valve limiting device (9), an axial blind hole is arranged at the end, and the edge of the axial blind hole of the valve rod (1) extending out of the hole of the compression valve limiting device (9) bends outwards along the radial direction. The bottom valve assembly of the shock absorber can improve work efficiency, lower cost, guarantee product quality and shorten axial distance of the shock absorber.
Description
Technical field
The utility model relates to the vibration damper technical field, specifically is a kind of bottom valve assembly of vibration damper.
Background technique
In technique known; Bottom valve assembly by a kind of vibration damper is made up of compression valve snubber, valve block group, bottom valve, circulation sheet, spring sheet, pad, recuperation valve snubber, valve rod and nut; This compression valve snubber, valve block group, bottom valve, circulation sheet, spring sheet, pad, recuperation valve snubber are socketed on the valve rod successively; Said this nut screws the other end at valve rod; Nut axially fastens whole bottom valve assembly under certain moment loading, makes its final damping force that produces meet technical requirements.There is following defective in the bottom valve assembly of the vibration damper of above existing technology: the one, if in rundown process, exert oneself excessive easy damage screw rod, produce hidden danger of quality, and need do over again, increase cost; The 2nd, screw rod need stretch out a part of nut could lock, and has taken damper shaft to bulk, brings difficulty to the product specification manufacturing; The 3rd, need swivel nut when tightening, the cost regular hour, manufacturing efficiency is low.
The model utility content
The technical problem that the utility model will solve is to provide a kind of and can increase work efficiency, reduce cost, guarantee quality of product, shorten the bottom valve assembly of the vibration damper of vibration damper axial distance.
The technological scheme of the utility model is, a kind of bottom valve assembly with vibration damper of following structure is provided, and comprises the compression valve snubber, valve block group, bottom valve, circulation sheet, spring sheet, pad, the recuperation valve snubber that are socketed in successively on the valve rod; The end of said valve rod is provided with the axial limiting structure; The axial limiting structure of said valve rod is meant that the end of said valve rod is stretched out outside compression valve snubber hole and is provided with axial blind hole, and this valve rod to stretch out the edge of the axial blind hole outside the compression valve snubber hole radially outwardly-bent.
After adopting said structure, the utility model compared with prior art has the following advantages: because the axial limiting structure of said valve rod is meant; The end of said valve rod is stretched out outside compression valve snubber hole and is provided with axial blind hole, and this valve rod to stretch out the edge of the axial blind hole outside the compression valve snubber hole radially outwardly-bent, just the end of valve rod is for adopting riveted fixing; Earlier required part is placed on the worktable of press after all correct assembling man-hour adding; The top centermost of press is furnished with drift, and both sides are furnished with briquetting, and briquetting compresses the recuperation valve snubber; Drift is out of shape the axial blind hole impact extruded downwards, thereby the bottom valve assembly is fastening.Have following having a few like this: the one, the riveted joint time is short, and manufacturing efficiency is high; The 2nd, avoid damaging screw rod, guarantee to produce quality; The 3rd, shortened the vibration damper axial distance.
Description of drawings
Accompanying drawing 1 is the structural representation of bottom valve assembly of the vibration damper of the utility model.
Accompanying drawing 2 is processing schematic representation of bottom valve assembly of the vibration damper of the utility model.
As shown in the figure: 1, valve rod, 2, briquetting, 3, the recuperation valve snubber, 4, pad, 5, spring sheet, 6, the circulation sheet, 7, bottom valve, 8, the valve block group, 9, the compression valve snubber, 10, drift.
Embodiment
Be described further below in conjunction with the bottom valve assembly of accompanying drawing the vibration damper of the utility model.
As shown in Figure 1, the bottom valve assembly of the vibration damper of the utility model comprises the compression valve snubber 9, valve block group 8, bottom valve 7, circulation sheet 6, spring sheet 5, pad 4, the recuperation valve snubber 3 that are socketed in successively on the valve rod 1; The end of said valve rod 1 is provided with the axial limiting structure; The axial limiting structure of said valve rod 1 is meant; The end of said valve rod 1 is stretched out outside compression valve snubber 9 holes and is provided with axial blind hole; And it is radially outwardly-bent that this valve rod 1 stretches out the edge of the axial blind hole outside compression valve snubber 9 holes, just is washed into horn mouth.
As shown in Figure 2, the bottom valve assembly of the vibration damper of the utility model assembling locking method: valve rod 1 is machining screw not, an end of valve rod 1 is processed the axial blind hole of certain-length, and total length shortens.Be placed on the worktable of press after all correct assembling of the part that the bottom valve assembly is required; Briquetting 2 compresses recuperation valve snubber 3; Drift 10 faces the axial blind hole center, under the press effect, impacts the axial blind hole port, and the axial blind hole port extends to the periphery distortion; Spacing and jam-packed recuperation valve snubber 3, the bottom valve assembly is fastening the most at last.
