Abstract
The utility model discloses a shock absorber, which comprises a shock absorber body, a piston rod, a dust cover, a buffer block and a cover buckle. The protective cover buckle is provided with a locking dummy club, a knurling combined surface, an annular stiffener, a discharge channel, a discharge hole, a vertical discharge slot, a long through hole and an annular stiffener fillet; the lower end of the dust cover is provided with a groove; the buffer block is arranged on the piston rod in the dust cover, the protective cover buckle is arranged on the front end of the shock absorber body through interference fastening, and the groove on the lower end of the dust cover is buckled in the corresponding locking dummy club of the protective cover buckle so as to fix the dust cover. The utility model has the advantages of convenient manufacture and installation, low cost and light weight. The knurling structure of the combined surface increases the frictional force of the protective cover buckle, realizes tighter combination of the protective cover buckle and the shock absorber body and can not be loosened in the case with the upward tension of the dust cover. Moreover, the annular stiffener enhances the shock resistance of the protective cover buckle.
Description
Technical field
The utility model belongs to mechanical engineering and vehicle suspension technical field, relates to a kind of vibration damper, relates in particular to a kind of protecting cover snap close integral type vibration damper; Be specially adapted to the fixed installation of shock absorber dirt shield.
Background technique
Existing vehicle shock absorber end adopts metal or plastic cover that oil sealing is protected, and prevents the impact energetically that silt is invaded and born buffer stopper; The outside dust-proof cover that adopts of vibration damper protects, and avoids rubble to impact piston rod, reduces the erosion to piston rod and oil sealing of muddy water and dust.The lower end of dust-proof cover and the means of fixation of vibration damper have multiple, the various forms of dust-proof cover snap closes of most employings.The dust-proof cover snap close needs independent die sinking to make the cost height; Protecting cover and the assembling of dust-proof cover snap close are installed loaded down with trivial details.
Summary of the invention
The utility model discloses a kind of vibration damper, to solve the independent die sinking fabricating cost of shock absorber dirt shield snap close height in the prior art, problems such as loaded down with trivial details are installed.
The utility model vibration damper comprises vibration damper body, piston rod, dust-proof cover, buffer stopper; It is characterized in that: also comprise the protecting cover snap close; Have the locking boss on the protecting cover snap close, the dust-proof cover lower end has groove; The fastening vibration damper body front end that is installed in of protecting cover snap close, buffer stopper are installed on the interior piston rod of dust-proof cover, and dust-proof cover lower end groove buckles on the locking boss of corresponding protecting cover snap close, fixedly dust-proof cover.
On protecting cover snap close and the vibration damper body interference fit face annular knurl junction plane is arranged.Through the junction plane of annular knurl, increased the frictional force of protecting cover snap close, make the protecting cover snap close more tight with combining of vibration damper body, prevent the protecting cover snap close because the pulling force that dust-proof cover makes progress gets loose the protecting cover snap close.
Protecting cover snap close upper edge has cyclic reinforcing rib, strengthens vertical impact resistance of protecting cover snap close.Protecting cover snap close upper edge cyclic reinforcing rib has chamfering.Play the guiding role through the stiffening rib of the chamfering buffer stopper in can the impact process, prevent that buffer stopper from impacting cracked back chip and entering protecting cover snap close inside.
There is 3-12 current by pass protecting cover snap close upper end, and channel end has discharge orifice.Current by pass and channel end discharge orifice are got rid of the muddy water that enters dust-proof cover inside; Disperse to dredge the downward impact air-flow of buffer stopper, prevent that oil seal lip is subjected to high pressure draught for a long time and impacts.
Relative with current by pass on the protecting cover snap close should have 3-12 vertically dredging flow groove, and vertically long through-hole is arranged accordingly at the dredging flow groove bottom.Vertically dredging flow groove and long through-hole distribute the heat that the vibration damper body sends, and dredge the air-flow that dust-proof cover compresses generation repeatedly.
The utility model has the advantages that: make with easy for installation, cost is low, and is in light weight.Junction plane annular knurl structure has increased protecting cover snap close frictional force, makes the protecting cover snap close tighter with combining of vibration damper body, can not get loose phenomenon being subjected to dust-proof cover under the situation of upper pulling force.Cyclic reinforcing rib strengthens the shock resistance of protecting cover snap close.
Description of drawings

Fig. 2 protecting cover snap close external structure schematic representation;
Fig. 3 protecting cover snap close internal structure schematic representation.
Among the figure: 1 vibration damper body, 2 piston rods, 3 dust-proof cover, 4 buffer stoppers, 5 protecting cover snap closes, 5a locking boss, 5b annular knurl junction plane, 5c cyclic reinforcing rib, 5d current by pass, 5e discharge orifice, the vertical dredging flow groove of 5f, 5g long through-hole.
Embodiment
The utility model first embodiment is as shown in Figure 1: the utility model comprises vibration damper body 1, piston rod 2, dust-proof cover 3, buffer stopper 4, protecting cover snap close 5.As Fig. 2, shown in Figure 3: have locking boss 5a, annular knurl junction plane 5b, cyclic reinforcing rib 5c, current by pass 5d, discharge orifice 5e, vertically dredging flow groove 5f, long through-hole 5g on the protecting cover snap close 5, and the cyclic reinforcing rib chamfering;
As shown in Figure 1: buffer stopper 4 is installed on the piston rod 2 in the dust-proof cover 3, fastening vibration damper body 1 front end that is installed in of protecting cover snap close 5 interference, dust-proof cover 3 lower ends have groove, dust-proof cover 3 lower end grooves buckle on the locking boss 5a of corresponding protecting cover snap close 5, fixed installation protecting cover snap close 5 and dust-proof cover 3.Protecting cover snap close 5 with vibration damper body 1 interference fit face on annular knurl junction plane 5b, increased the frictional force of protecting cover snap close 5, make protecting cover snap close 5 more tight with combining of vibration damper body 1, prevent from protecting cover snap close 5 to be got loose owing to the pulling force that dust-proof cover 3 makes progress.Protecting cover snap close 5 upper edge cyclic reinforcing rib 5c have strengthened vertical impact resistance of protecting cover snap close 5.Protecting cover snap close 5 upper edge cyclic reinforcing rib chamferings, the buffer stopper 4 in the impact process play the guiding role, and prevents that buffer stopper 4 from impacting cracked back chip and entering protecting cover snap close 5 inside.There are 3 current by pass protecting cover snap close 5 upper ends, and channel end has discharge orifice.Current by pass and channel end discharge orifice are got rid of the muddy water that enters dust-proof cover inside; Disperse to dredge the downward impact air-flow of buffer stopper, prevent that oil seal lip is subjected to high pressure draught for a long time and impacts.
Relative with current by pass on the protecting cover snap close should have 3 vertical dredging flow grooves, and vertically long through-hole is arranged accordingly at the dredging flow groove bottom.Vertically dredging flow groove distributes the heat that the vibration damper body sends with long through-hole, the air-flow of generation when dredging dust-proof cover and compressing repeatedly.
