Abstract
The utility model discloses a kind of oil pressure attenuator, comprise piston rod, compression grease chamber, test valve, rubber pad, return opening, bearing, iron core, inner cylinders, buffer, piston, outer inside casing and Returnning spring; The inner one end of described outer inside casing is provided with piston rod; Described piston rod and outer inside casing joint are provided with iron core; One end of described piston rod is provided with piston; Liquid oils is filled with between described outer inside casing and inner cylinders; Compression grease chamber and Returnning spring is also provided with in described inner cylinders; Described compression grease chamber upper end fixing seal test valve; Installed rubber pad in the middle part of described test valve, right-hand member offers return opening; A buffer has all been installed at the two ends of described outer inside casing inside.This oil pressure attenuator, when piston constantly carries out piston movement, shock-absorbing oil flows to Inner cylinder by test valve, and such system constantly and step by step absorbs external impact, utilizes buffer can absorb impact and noise efficiently simultaneously, can freely control shock-absorbing scope.
Description
Technical field
the utility model relates to attenuator applied technical field, especially a kind of oil pressure attenuator.
Background technique
at present, the rear wheel drive vehicle transmission system of domestic majority is single motor, speed changer, transmission shaft, rear bridge system, vehicle traction is realized by this mechanism, along with the increase day by day that progress and the people of whole automotive engineering require vehicle riding comfort, the vibration of whole transmission system is had higher requirement, and in the vehicle produced in batches, carry out the cost that brand-new technology upgrading increases to whole transmission system huge.
therefore, how on the basis reduced costs, solve transmission system and to resonate the problem of the riding comfort difference caused, become the technical problem that those skilled in the art are urgently to be resolved hurrily.
prior art is difficult to the productive life needs meeting people, in order to solve above-mentioned Problems existing, the utility model proposes a kind of oil pressure attenuator.
for realizing this technical purpose, the technical solution adopted in the utility model is: a kind of oil pressure attenuator, comprises piston rod, compression grease chamber, test valve, rubber pad, return opening, bearing, iron core, inner cylinders, buffer, piston, outer inside casing and Returnning spring; The inner one end of described outer inside casing is provided with piston rod; Described piston rod and outer inside casing joint are provided with iron core; One end of described piston rod is provided with piston; Liquid oils is filled with between described outer inside casing and inner cylinders; Compression grease chamber and Returnning spring is also provided with in described inner cylinders; Described compression grease chamber upper end fixing seal test valve; Installed rubber pad in the middle part of described test valve, right-hand member offers return opening; A buffer has all been installed at the two ends of described outer inside casing inside.
as further technological scheme of the present utility model: described rubber pad is provided with 3, when piston rod does piston movement, protection Returnning spring prevents from coming off.
further, described outer inside casing and piston rod joint are sealed by seal ring.
further, the Dimensions of described attenuator is 3600mm-3650mm.
compared with prior art, the utility model has following beneficial effect: this oil pressure attenuator, and when moving object collision piston rod with certain mass, piston enters Inner cylinder, in such cylinder, shock-absorbing oil passing hole flows into outer shell and the large portion of Inner cylinder, and too much shock-absorbing oil enters in damping device temporarily; When collision object is removed, piston is very fast to be resetted by Returnning spring, and shock-absorbing oil flows to Inner cylinder by test valve, and such system constantly and step by step absorbs external impact, utilize buffer can absorb impact and noise efficiently simultaneously, can freely control shock-absorbing scope.
Summary of the invention
Accompanying drawing explanation
fig. 1 is overall structure schematic diagram of the present utility model.
in figure: 1 piston rod, 2 compression grease chambeies, 3 test valves, 4 rubber pads, 5 return openings, 6 bearings, 7 iron cores, 8 inner cylinders, 9 buffers, 10 pistons, 11 oil, 12 outer inside casings and 13 Returnning springs.
Embodiment
below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
refer to Figure of description 1, in the utility model embodiment, a kind of oil pressure attenuator, comprises piston rod 1, compression grease chamber 2, test valve 3, rubber pad 4, return opening 5, bearing 6, iron core 7, inner cylinders 8, buffer 9, piston 10, outer inside casing 12 and Returnning spring 13; Described inner one end of outer inside casing 12 is provided with piston rod 1; Described piston rod 1 is provided with iron core 7 with outer inside casing 12 joint; One end of described piston rod 1 is provided with piston 10; Liquid oils 11 is filled with between described outer inside casing 12 and inner cylinders 8; Compression grease chamber 2 and Returnning spring 13 is also provided with in described inner cylinders 8; Described compression grease chamber 2 upper end fixing seal test valve 3; Installed rubber pad 4 in the middle part of described test valve 3, right-hand member offers return opening 5; A buffer 9 has all been installed at the two ends of described outer inside casing 12 inside.
as further technological scheme of the present utility model: described rubber pad 4 is provided with 3, when piston rod 1 does piston movement, protection Returnning spring 13 prevents from coming off.
further, described outer inside casing 12 is sealed by seal ring with piston rod 1 joint.
further, the Dimensions of described attenuator 9 is 3600mm-3650mm.
the utility model is waited in use, and when moving object collision piston rod with certain mass, piston enters Inner cylinder, and in such cylinder, shock-absorbing oil passing hole flows into outer shell and the large portion of Inner cylinder, and too much shock-absorbing oil enters in damping device temporarily; When collision object is removed, piston is very fast to be resetted by Returnning spring, and shock-absorbing oil flows to Inner cylinder by test valve, and such system constantly and step by step absorbs external impact, this makes it possible to send piston to process impact; And interior pipe is furnished with porous, outer tube is provided with elongated slot, and such outer tube can be adjusted by screw thread.
to those skilled in the art, but the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
