Abstract
The utility model provides an automobile shock absorber with a dust cover locking piece, which includes a working cylinder barrel, and an oil storage cylinder barrel, wherein a piston rod, a piston, a guide sleeve, a dust cover and an oil seal are arranged in the working cylinder barrel. The automobile shock absorber is characterized in that a shoulder step is arranged at the end part of the piston rod; the dust cover is arranged on the piston rod in a sleeving manner, and is pushed against the shoulder step; and a locking piece is further arranged on the piston rod, and is matched with the dust cover in a positioning manner. According to the utility model, the original structure that the dust cover is fixed through the bolt is abolished, and the dust cover is fixed through the shoulder step and the locking piece on the piston rod, so that looseness or falling-off condition can be avoided, the dust cover is fixed more stably, and the reliability of the shock absorber under the working state is improved at the same time.
Description
Technical field
The utility model relates to a kind of automobile absorber, especially a kind of automobile absorber that has the dust-proof cover locking element.
Background technique
For improving the automobile running stationarity; Common meeting mounting shock absorber in the automotive suspension; The current vibration damper that adopts on the market is hydraulic damper mostly, and its working principle is when receiving vibrations relative movement to occur between vehicle frame and vehicle bridge, the piston up-down in the vibration damper; Fluid in the vibration damper chamber just flows in another chamber from a chamber through different spaces repeatedly; The intermolecular interior friction of friction between hole wall and fluid and fluid at this moment forms damping force to vibrations, and making the thump Conversion of energy is the heat energy of fluid, is dispersed in the air by the vibration damper absorption again.
Present two-way function telescopic shock absorber has been drawn together work cylinder barrel, oil storage cylinder barrel usually, and dust-proof cover, guide sleeve, oil sealing are provided with piston rod, piston, bottom valve in the work cylinder barrel; Described piston sleeve is located on the piston rod, and the piston cylinder barrel of will working is separated into upper and lower two chambers, and piston is provided with rebound valve; Flowing valve, bottom valve are arranged on the lower chambers bottom, and bottom valve comprises recuperation valve, compression valve; Its working principle is: when compression stroke, vibration damper by compression, this moment piston move downward; The volume of piston upper chamber chamber reduces, and oil pressure raises, and the fluid flowing valve of flowing through flows to upper chamber; Epicoele is by piston rod a part of space that accounts for, thereby the volume that reduces of the volume light rain cavity of resorption that increases of epicoele, flows back to oil storage cylinder so a part of fluid is pushed compression valve open.When extension stroke, vibration damper is stretched, and at this moment the piston of vibration damper moves upward; The piston upper chamber oil pressure raises, and flowing valve is closed, and the fluid in the epicoele is pushed rebound valve open and flowed into cavity of resorption; Because the existence of piston rod; The fluid that flows into from epicoele is not enough to be full of the volume that cavity of resorption increases, and impels cavity of resorption to produce certain degree of vacuum, and at this moment the fluid in the oil storage cylinder is pushed recuperation valve open and flowed into cavity of resorption and replenish.
Summary of the invention
In order to overcome the deficiency of existing technology, the utility model provides a kind of more stable work, the automobile absorber that has the dust-proof cover locking element that reliability is higher.
The utility model solves the technological scheme that its technical problem adopted: a kind of automobile absorber that has the dust-proof cover locking element; Include work cylinder barrel, oil storage cylinder barrel; Work is provided with piston rod, piston, guide sleeve, dust-proof cover and oil sealing in the cylinder barrel, it is characterized in that: said piston rod end is provided with the shoulder rank, and said dust-proof cover is sheathed on the piston rod and is inconsistent with these shoulder rank; Also be provided with locking element on the piston rod, this locking element constitutes the location with dust-proof cover and cooperates.
Adopt technique scheme; Cancel the structure that former useful bolt fixes dust-proof cover; The shoulder rank and the locking element that are employed on the piston rod are realized fixing dust-proof cover; Situation loosening or that come off then can not appear, and feasible more stable to fixing of dust-proof cover, also improved the reliability under the vibration damper working state simultaneously.
Further being set to of the utility model: end, dust-proof cover place is provided with outside thread on the said piston rod, and locking element includes locking nut, and the location that locking nut is sheathed on outside thread place on the piston rod and constitutes dust-proof cover cooperates.
Adopt technique scheme, the form that locking element adopts bolt plays the effect of fixed connection to dust-proof cover, has made things convenient for installation, maintenance and better to dust-proof cover, and is more convenient in operation.
Further being set to again of the utility model: said locking element also includes packing ring and the entrucking annex that can be connected with external equipment, and packing ring, entrucking annex and locking nut compress dust cover successively.
Adopt technique scheme; Locking element also includes the entrucking annex that is fixed in the piston rod end; The installation of other supplementary equipment on this entrucking annex convenience and the vibration damper; And made things convenient for being connected of vibration damper and automobile other component, and packing ring is between entrucking annex and dust-proof cover, make two kinds more firm in fixing.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the utility model embodiment's a schematic representation.
Fig. 2 is the schematic representation of the utility model embodiment piston rod.
Embodiment
Like Fig. 1, shown in 2; Present embodiment includes work cylinder barrel 11, oil storage cylinder barrel 12; Work is provided with piston rod 2, piston 7, guide sleeve 3, dust-proof cover 4 and oil sealing 5 in the cylinder barrel 11, and said guide sleeve 3 is arranged between piston rod 2 and the oil storage cylinder barrel 12, with clutch release slave cylinder 11 interference fit, and oil storage cylinder barrel 12 Spielpassung; Said oil sealing 5 is arranged between guide sleeve 3 and the oil storage cylinder barrel 12; Closely cooperate with guide sleeve 3, be slidingly connected with piston rod 2, be provided with dust-proof cover 4 with oil sealing 5 inconsistent ends on the piston rod 2, dust-proof cover 4 is provided with through hole.Wherein, End, dust-proof cover 4 place is provided with shoulder rank 21 on the piston rod 2; Dust-proof cover 4 is sheathed on the piston rod 2 and is inconsistent with these shoulder rank 21; End, dust-proof cover 4 place is provided with outside thread 22 on the piston rod 2, also is provided with locking element 6 on the piston rod 2, and locking element 6 is installed in dust-proof cover 4 with respect to takeing on the location cooperation that rank 21 belong to the opposite side of sides and constitute dust-proof cover 4.Locking element 6 includes packing ring 62 and the entrucking annex 63 that can be connected with external equipment, and packing ring 62, entrucking annex 63 and locking nut 61 compress dust cover 4 successively, and locking nut 61 is positioned at outside thread 22 places on the piston rod 2, thereby the location that constitutes dust cover 4 cooperates.
