Abstract
The utility model discloses a single-cylinder hydraulic damper, which comprises an oil storage cylinder, an oil seal sub-assembly, a guide device, a connecting rod and a piston mounted on the connecting rod. The single-cylinder hydraulic damper is characterized in that a passage valve is arranged at the upper end of the piston and a reset valve is arranged at the upper end of the piston so that a piston valve sub-assembly is formed, a bottom valve sub-assembly is further arranged in the oil storage cylinder below the piston valve sub-assembly and provided with a compensation valve and a compression valve, an oil hole is arranged on the side wall of the oil storage cylinder below the bottom valve sub-assembly, an oil storage rubber pipe and a seal cover are fixed to outside of the oil storage cylinder from inside to outside, and the oil hole is positioned inside the oil storage rubber pipe. Compared with a two-cylinder damper or three-cylinder damper, the single-cylinder hydraulic damper is simple in structure and low in cost, and is capable of realizing the characteristic of bidirectional functional damping, so that fine damping performance is ensured.
Description
Technical field
The utility model relates to a kind of monotubular formula hydraulic damper.
Background technique
The cylinder type hydraulic damper that is used for vehicle shock absorber has structures such as monotubular formula damper, double barreled damper, three cartridge type dampers, and the structure of dampers such as double barreled damper and three cartridge type dampers is all comparatively complicated, its better performances, but cost is higher; The monotubular formula damper that uses comprises oil storage cylinder, oil sealing sub-assembly, guider, connecting rod, is loaded on the piston on the connecting rod at present, during assembling, inject certain vibration damper fluid in the oil storage cylinder, make fluid keep suitable height, and inject certain air at the oil storage cylinder epicoele, this monotubular formula damper belongs to single effect formula damper, its working principle is simple, only when restoring stroke, produce damping force, do not have compression damping power, its performance imperfection.
The model utility content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of monotubular formula hydraulic damper is provided, and it has advantage simple in structure, that cost is low, can realize the beidirectional damping characteristic again, can guarantee good damping performance.
For achieving the above object, monotubular formula hydraulic damper of the present utility model, comprise oil storage cylinder, oil sealing sub-assembly, guider, connecting rod, be loaded on the piston on the connecting rod, it is characterized in that being provided with flowing valve in the upper end of piston, upper end at piston is provided with rebuilt valve, form the piston valve sub-assembly, also be provided with sub assembly of bottom valve in the oil storage cylinder below the piston valve sub-assembly, sub assembly of bottom valve is provided with recuperation valve and compression valve; Be provided with oilhole on the oil storage cylinder sidewall below the sub assembly of bottom valve, a store oil rubber pipe and seal closure are fixed in outside the oil storage cylinder from the inside to the outside, and oilhole is positioned at the store oil rubber pipe.
Sub assembly of bottom valve is divided into two chambeies up and down with oil storage cylinder, epicoele plays the clutch release slave cylinder effect in the bitubular damper, connecting rod and piston valve sub-assembly can slide in this chamber, and the surge drum effect of dual-tube shock absorber is played in the space that cavity of resorption and store oil rubber pipe produce because of expanding, and store fluid and compensation fluid; During use, the fluid part that to inject oil storage cylinder in oil storage cylinder when connecting rod presses down flows into cavity of resorption by sub assembly of bottom valve, cavity space is limited down for cause, unnecessary fluid flow in the store oil rubber pipe by oilhole, the store oil rubber pipe expands because of flowing into increasing of fluid, in this process, recuperation valve, compression valve and store oil rubber pipe all play damping function; When connecting rod stretches in oil storage cylinder, the store oil rubber pipe shrinks to be clamp-oned fluid in the oil storage cylinder by oilhole, because of shrinking, the store oil rubber pipe produces very big spring-back force, to clamp-on that fluid enters in the liquid container by sub assembly of bottom valve fast in the oil storage cylinder, flowing valve and rebuilt valve can play damping function, realize the beidirectional damping characteristic;
As further improvement of the utility model, on the oil storage cylinder inwall, be provided with two positioning convex strips of annular, described sub assembly of bottom valve is loaded between two positioning convex strips; Can be firmly fixing sub assembly of bottom valve, and simple in structure;
In sum, the utility model has advantage simple in structure, that cost is low with respect to double barreled damper or three cartridge type dampers, can realize the beidirectional damping characteristic again, can guarantee good damping performance.
Description of drawings
Fig. 1 is the utility model embodiment's a plan view.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, this monotubular formula hydraulic damper, comprise oil storage cylinder 1, oil sealing sub-assembly 2, guider 3, connecting rod 4, be loaded on the piston 5 on the connecting rod 4, be provided with flowing valve 6 in the upper end of piston 5, be provided with rebuilt valve 7 in the upper end of piston 5, form the piston valve sub-assembly, at the sub assembly of bottom valve 8 that also is provided with below the piston valve sub-assembly between two positioning convex strips 14 that are fixed in annular on the oil storage cylinder inwall, sub assembly of bottom valve is provided with recuperation valve 9 and compression valve 10; Be provided with oilhole 11, one store oil rubber pipes 12 and seal closure 13 and be fixed in outside the oil storage cylinder 1 by the structure that closes up from the inside to the outside on 1 sidewall of the oil storage cylinder below the sub assembly of bottom valve 8, oilhole 11 is positioned at store oil rubber pipe 12.
Sub assembly of bottom valve 8 is divided into two chambeies up and down with oil storage cylinder 1, epicoele plays the clutch release slave cylinder effect in the bitubular damper, connecting rod 4 and piston valve sub-assembly can slide in this chamber, the surge drum effect of dual-tube shock absorber is played in the space that cavity of resorption and store oil rubber pipe 12 produce because of expanding, and stores fluid and compensation fluid; During use, connecting rod 4 will inject oil storage cylinder 1 when pressing down in oil storage cylinder 1 a fluid part flows into cavity of resorption by sub assembly of bottom valve 8, cavity space is limited down for cause, unnecessary fluid flow in the store oil rubber pipe 12 by oilhole 11, store oil rubber pipe 12 expands because of flowing into increasing of fluid, in this process, recuperation valve 9, compression valve 10 and store oil rubber pipe 12 all play damping function; When connecting rod 4 stretches in oil storage cylinder 1, store oil rubber pipe 12 shrinks to be clamp-oned fluid in the oil storage cylinder 1 by oilhole 11, because of shrinking, store oil rubber pipe 12 produces very big spring-back force, fluid in the oil storage cylinder cavity of resorption is entered the liquid container epicoele by sub assembly of bottom valve fast, guaranteed that fluid all takes the space, thereby guaranteed the satisfactory of indicator diagram shape, not distortion and idle running; Flowing valve 6 and rebuilt valve 7 can play damping function, realize the beidirectional damping characteristic, can guarantee good damping performance.
