Description
Technical field
The utility model relates to a kind of vibration damper, particularly relates to a kind of vibration damper with dust-proof effect.
Background technique
Vibration damper is the essential element on automobile.In prior art, be disclose the vibration damper that a kind of liquid has dust-proof effect in the Chinese invention patent of 201210405079.7 in the patent No., it comprises main spring cup, top in main spring cup is filled with rubber, rubber is embedded with the main spring core inserts be fixedly connected with operator cabin construction bolt, the rim of a cup position of main spring cup is provided with the anti-arm-tie for being connected with vehicle frame, the middle part of anti-arm-tie is provided with the through hole passed for operator cabin construction bolt, the radial dimension of through hole is less than the radial dimension of main spring core inserts, between the hole wall of through hole and operator cabin construction bolt, there is transverse vibration gap, between anti-arm-tie and main spring core inserts, there is the vertical bump clearance.When this vibration damper is installed, anti-arm-tie is fixedly connected with vehicle frame, and when occurring to overturn, main spring core inserts can not realize the connection keeping operator cabin and vehicle frame through anti-arm-tie.
Vibration damper in above-mentioned patent, it is mutual unsettled setting between its spring and piston rod, when automobile operationally, vehicle body can shake, cause damping damper to shake together, now may there is radial rocking in spring, comes in contact with the outer wall of piston rod thereupon, and due to spring be occur in axial sliding along piston rod all the time in tensioning and lax process, this just causes the situation that may occur between spring and piston rod to wear and tear.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide one can prevent spring and piston rod from coming in contact and wearing and tearing, and has the vibration damper of dust-proof effect.
For achieving the above object, the utility model provides following technological scheme: a kind of vibration damper with dust-proof effect, include cylindric cylinder body and piston rod, described cylinder interior hollow is formed with receiving cavity, the sealing of described cylinder body one end, the end face of the other end offers through hole, the size of described through hole and the external diameter adaptation of described piston rod, described piston rod one end extends in receiving cavity through described through hole, the other end of described piston rod extends in the outside of described cylinder body, and described piston rod can slide relative to described cylinder body, on described piston rod, compartment of terrain is arranged with first piston, second piston and the 3rd piston, described first piston, second piston and the 3rd piston are all arranged in described receiving cavity, and described first piston, the outward edge of the second piston and the 3rd piston is resisted against on the inwall of described receiving cavity, spring is clamped with between described second piston and the 3rd piston, described spring one end is connected on the second piston, the other end is connected on described 3rd piston,
Between described spring and described piston rod, be provided with anti-wear cover, described anti-wear cover is socketed on described piston rod.
As improvement of the present utility model, described anti-wear cover is made up of brass, and has lubricant grease at its surface smear.
As preferably of the present utility model, be provided with Sealing in described receiving cavity, described Sealing is fixed on described cylinder body and offers on one end of through hole.
Compared with prior art, the utility model has the advantage of: by arranging an anti-wear cover between piston rod outer wall and spring, thus avoid piston rod and spring to occur directly to contact, prevent them from wearing and tearing thus, extend working life; In addition, by being socketed a dust cover in cylinder body outside, this dust cover is arched towards the bottom of cylinder body by the joint of piston rod and cylinder body, makes dust can not enter into cylinder interior easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of the vibration damper in the utility model with dust-proof effect.
Embodiment
Be described further with reference to the embodiment of Fig. 1 to the vibration damper in the utility model with dust-proof effect.
As shown in Figure 1, the present embodiment is a kind of vibration damper with dust-proof effect, include cylindric cylinder body 1 and piston rod 2, described cylinder interior hollow is formed with receiving cavity 3, the sealing of described cylinder body one end, the end face of the other end offers through hole (not shown), the size of described through hole and the external diameter adaptation of described piston rod, described piston rod one end extends in receiving cavity through described through hole, the other end of described piston rod extends in the outside of described cylinder body, and described piston rod can slide relative to described cylinder body, on described piston rod, compartment of terrain is arranged with first piston 4, second piston 5 and the 3rd piston 6, described first piston, second piston and the 3rd piston are all arranged in described receiving cavity, and described first piston, the outward edge of the second piston and the 3rd piston is resisted against on the inwall of described receiving cavity, spring 7 is clamped with between described second piston and the 3rd piston, described spring one end is connected on the second piston, the other end is connected on described 3rd piston,
Anti-wear cover 8 is provided with between described spring and described piston rod, described anti-wear cover is socketed on described piston rod, dust cover is connected in the outer cover of described cylinder body, described dust cover is made of plastics, described dust cover includes lid and cover rim, described lid is that arc surface is arranged, and described cover rim is circumferentially fixed on lid.
