Description
Technical field
The utility model relates to a kind of vibration damper, relates in particular to a kind of automobile hydraulic double-drum type vibration damper.
Background technique
Automobile absorber is one of most important parts in the automobile chassis system, traditional automobile absorber main structure has piston rod, oil sealing, clutch release slave cylinder, piston, oil storage cylinder, compression valve and guide sleeve etc., described guide sleeve is arranged between piston rod and the oil storage cylinder, with the clutch release slave cylinder interference fit, with the oil storage cylinder Spielpassung, described oil sealing is arranged on guide sleeve and the oil storage cylinder between the end seal plate, closely cooperate with guide sleeve, be slidingly connected with piston rod, clutch release slave cylinder only guarantees the coaxality of itself and oil storage cylinder by guide holder, when on the automobile running flat road surface, vibrated between vehicle frame and vehicle bridge and relative moving up and down occurred, piston in the vibration damper moves up and down, fluid in the vibration damper chamber just flows in another chamber through different holes from a chamber repeatedly, the at this moment friction between hole wall and fluid and the intermolecular interior friction of fluid forms damping force to vibration, make automobile vibrational energy be converted into fluid heat energy, be dispersed into the damping that has realized automobile in the atmosphere by the vibration damper absorption again.But this vibration damper in the course of the work fluid by the hole on the piston during from the entering piston top and enter oil storage cylinder from compression valve of piston bottom, because the existence of pressure difference, so that fluid enters piston top from the piston bottom and enter the process of oil storage cylinder from compression valve and can produce bubble, simultaneously because in the running process of automobile, piston rod all is to carry out the high frequency motion usually, so just cause easily vibration damper to produce distortion, simultaneously so that piston rod produces vibration in movement process, thereby make the vibration damper noise become large, and then shorten vibration damper working life, and reduce damping effect.
The model utility content
For the prior art above shortcomings, the purpose of this utility model just is to provide a kind of automobile hydraulic double-drum type vibration damper, can effectively reduce vibration damper produces distortion under the high-frequency operation state probability, the noise that produces when reducing simultaneously vibration damper work, thereby the raising damping effect prolongs the vibration damper life-span.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of automobile hydraulic double-drum type vibration damper, comprise piston rod, oil sealing, guide holder, clutch release slave cylinder, piston, oil storage cylinder and compression valve, described guide holder is arranged between piston rod and the oil storage cylinder, and with the clutch release slave cylinder interference fit, with the oil storage cylinder Spielpassung, described oil sealing is arranged on guide holder and the oil storage cylinder between the end seal plate, closely cooperate with guide holder, be slidingly connected with piston rod, described compression valve is arranged on the lower end of clutch release slave cylinder, it is characterized in that: also comprise the first throttle device, the second throttling arrangement and the 3rd throttling arrangement, described first throttle device is arranged between clutch release slave cylinder and the oil storage cylinder and is positioned at the clutch release slave cylinder lower end, and the second throttling arrangement and the 3rd throttling arrangement are set up in parallel up and down between piston rod and clutch release slave cylinder and with piston rod and are fixedly connected with.
By the first throttle device being set between clutch release slave cylinder and the oil storage cylinder, the second throttling arrangement and the 3rd throttling arrangement being set between piston rod and clutch release slave cylinder, be subject to the resistance of throttling arrangement when making fluid flow through first throttle device, the second throttling arrangement and the 3rd throttling arrangement, thereby make the pressure decreased of fluid, make fluid energy consumption partial loss, thereby avoid producing the turbid phenomenon of vapour, and then effectively having reduced the generation of bubble, the two-stage throttling is adopted in the piston top, can reduce better the generation of bubble.Because bubble reduces, so that producing the probability of distortion under the high-frequency operation state, reduces by vibration damper; Owing to bubble reduces, the vibration that vibration damper produces in the course of the work also reduces simultaneously, thus the noise that has produced when having reduced vibration damper work, and improve damping effect, the prolongation vibration damper life-span.
Further, described first throttle device, the second throttling arrangement and the 3rd throttling arrangement comprise respectively first throttle porose disc, second section discharge orifice dish and the 3rd throttling porose disc, and first throttle porose disc, second section discharge orifice dish and the 3rd throttling porose disc are all ringwise; Wherein, the first throttle porose disc is set on the clutch release slave cylinder, and second section discharge orifice dish and the 3rd throttling porose disc all are set on the piston rod.Adopt the throttling porose disc, make fluid when flowing, be subject to the local resistance of restricting orifice, thereby so that the pressure decreased of fluid causes the fluid energy loss, and the fluid that passes the throttling porose disc more tends to be steady, thus make the throttling better effects if.
Further, the external diameter of described second section discharge orifice dish is less than the external diameter of the 3rd throttling porose disc.That is to say that second section discharge orifice dish circulation area is greater than the 3rd throttling porose disc circulation area; Because fluid has lost the part energy consumption after passing second section discharge orifice dish, fluid passes through again with again further loss part of the 3rd throttling porose disc energy consumption, fluid passes through piston valve body after through twice throttling loss of energy again, the throttling design that many places are muptiple-use, better reduce the generation of fluid bubble, noise when having reduced vibration damper work has improved damping effect.
Further, described first throttle device, the second throttling arrangement and the 3rd throttling arrangement also comprise respectively first throttle seat, the second throttle seat and the 3rd throttle seat, and described first throttle seat, the second throttle seat and the 3rd throttle seat are tubular structure and are solidified as a whole with first throttle porose disc, second section discharge orifice dish and the 3rd throttling porose disc respectively; The first throttle porose disc is fixed by first throttle seat and clutch release slave cylinder, and second section discharge orifice dish and the 3rd throttling porose disc are fixed by the second throttle seat and the 3rd throttle seat and piston rod respectively.First throttle device, the second throttling arrangement and the 3rd throttling arrangement link to each other with clutch release slave cylinder and piston rod by first throttle seat, the second throttle seat and the 3rd throttle seat respectively, make the area of contact of first throttle device, the second throttling arrangement and the 3rd throttling arrangement and clutch release slave cylinder and piston rod larger, thereby so that connect more stable, firm.
Compared with prior art, the utility model has the advantage of: simple in structure, by in vibration damper inside a plurality of throttling arrangements being set, thereby effect reduces vibration damper produces distortion under the high-frequency operation state probability, the noise that produces when reducing simultaneously vibration damper work, improve damping effect, and prolong the vibration damper life-span.
