Abstract
The utility model discloses an automotive shock absorber with dust removal brushes. The automotive shock absorber with the dust removal brushes comprises a cylinder body, a piston and a piston rod, wherein the end portion, arranged outside the cylinder body, of the piston rod serves as a locating end, the dust removal brushes are arranged facing the peripheral wall of the piston rod, and brush frames which are used for supporting the dust removal brushes are arranged on the cylinder body. According to the automotive shock absorber with the dust removal brushes, due to the fact that the peripheral wall of the piston rod is cleaned through the dust removal brushes which are erected on the brush frames, it is ensured that every time the piston rod retracts to a piston cavity, the dust removal brushes can brush away dust attached to the piston rod, and the dust is prevented form blocking a gap between the piston rod and the cylinder body. In addition, the distance between each dust removal brush and the peripheral wall of the piston rod, and the force of abutting between each dust removal brush and the peripheral wall of the piston rod can be adjusted by presetting the dust removal brushes.
Description
Technical field
The utility model relates to a kind of automobile absorber, especially a kind of automobile absorber with dust-removing brush.
Background technique
For the vibration of vehicle frame and vehicle body is decayed rapidly, improve smoothness and the travelling comfort of automobile running, vibration damper is generally all housed on automobile suspension system.And vibration damper is the rapid wear accessory in automobile using process, vibration damper work quality, by directly affecting the stationarity of automobile running and the life-span of other parts, therefore should make vibration damper often in good working order.
General existing automobile absorber is all with dust-proof cover, but dust-proof cover of the prior art mostly is open (non-vibration damper and spring are integrated), and dust-proof cover bottom is open, and has certain interval between vibration damper urceolus.Therefore, there is many technical problems in damper dust-proof cover of the prior art, as: 1, dust or silt are deposited on oil sealing and piston rod by lower openings, cause the scuffing of piston rod and oil sealing, cause leakage of oil, thereby reduce working life; 2, cause vibration damper hair fastener, when serious, will make vibration damper cisco unity malfunction, greatly affect the comfort property of car load.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of can be in piston rod be retracted piston cavity before, the automobile absorber with dust-removing brush that dust on piston rod is gone out.
The utility model solves the technological scheme that its technical problem adopts: a kind of automobile absorber with dust-removing brush, comprise cylinder body, piston and piston rod, the end that this piston rod is positioned at outside cylinder body is positioning end, described dust-removing brush is towards the perisporium setting of piston rod, and cylinder body is provided with for supporting the brush holder of described dust-removing brush.
Further be set to: hinged cooperation between described brush holder and cylinder body.
Adopt technique scheme, can realize brush holder and rotate around hinging shaft, thereby by rotating brush holder, the position of dust-removing brush is adjusted, can not only adjust recline distance and the dynamics of dust-removing brush and piston rod outer wall, and facilitate the installation and removal of dust-removing brush.
Further be set to: the working surface for brush piston rod perisporium on described dust-removing brush is arc surface, and the central angle of this arc surface is 60～180 °.
Adopt technique scheme, the working surface of dust-removing brush is with radian, thereby to greatest extent the perisporium of piston rod carried out to brush, improves the cleaning effect of dust-removing brush.
Further be set to: the quantity of described dust-removing brush is three, dust-removing brush distributes around the perisporium of piston rod symmetrically.
Adopt technique scheme, guarantee that dust-removing brush can carry out the action of brush all sidedly to piston rod circumferential position, thereby guarantee that the dust being attached on piston rod perisporium can thoroughly be cleared up.
Further be set to again: the working surface for brush piston rod perisporium on described dust-removing brush is arc surface, and the central angle of this arc surface is 120 °.
Adopt technique scheme, on each dust-removing brush, the central angle of working surface is 120 °, and therefore three dust-removing brushs can intactly be wrapped in the perisporium of piston rod, thereby 360 of piston rod ° of circumference are carried out to comprehensive brush.
The beneficial effects of the utility model are: by the dust-removing brush setting up on brush holder, piston rod perisporium is cleared up, thereby while guaranteeing in each piston rod retraction piston cavity, dust-removing brush all can be brushed the dust being attached on piston rod fall, and avoids stopping up in the gap between piston rod and cylinder body.In addition, dust-removing brush is apart from the distance of piston rod perisporium, and between the two mutually against dynamics, can be by setting in advance of dust-removing brush be adjusted.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation.
Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, 2, the present embodiment comprises the cylinder body 1 with piston cavity, and piston is installed in piston cavity, is connected with piston rod 2 on piston, and piston rod 2 wherein one end extends to outside cylinder body 1 and forms positioning end.
In order to protect, avoid entering dust between piston rod 2 and cylinder body 1 gap, the utility model also includes dust-removing brush 3, and this dust-removing brush 3 supports by the brush holder 4 being articulated with on cylinder body 1.The quantity of dust-removing brush 3 is three, and dust-removing brush 3 distributes around the perisporium of piston rod 2 symmetrically, and on dust-removing brush 3, the working surface for brush piston rod 2 perisporiums is arc surface, and the central angle of this arc surface is 120 °.Three dust-removing brushs 3 can intactly be wrapped in the perisporium of piston rod 2, thereby 360 of piston rod 2 ° of circumference are carried out to comprehensive brush.Wherein, 1 of brush holder 4 and cylinder body are hinged cooperation, therefore can to the position of dust-removing brush 3, adjust by rotating brush holder 4, can not only adjust recline distance and the dynamics of dust-removing brush 3 and piston rod 2 outer walls, and facilitate the installation and removal of dust-removing brush 3.
Certainly, the quantity of dust-removing brush 3 can be adjusted as required, and corresponding, the central angle of the working surface on dust-removing brush 3 also can according to circumstances adjust accordingly, and these adjustment belong to simple technique variation, therefore all fall in protection domain of the present utility model.
In the utility model, by 3 pairs of piston rod 2 perisporiums of dust-removing brush that set up on brush holder 4, clear up, thereby while guaranteeing in each piston rod 2 retraction piston cavity, dust-removing brush 3 all can be brushed the dust being attached on piston rod 2 fall, avoid stopping up in the gap of 1 of piston rod 2 and cylinder body.In addition, dust-removing brush 3 is apart from the distance of piston rod 2 perisporiums, and between the two mutually against dynamics, can be by setting in advance of dust-removing brush 3 be adjusted.
