Description
Technical field
The utility model relates to damper technical field, in particular to a kind of dustproof vibration-damper.
Background technique
In vehicle traveling process, especially suspension system is generated vibration by impacts such as road surfaces, in order to overcome driving process
In vibration, improve comfort property, damper be widely used in suspension system in existing automobile.The damper of existing automotive field with
Hydraulic damper, its working principle is that the piston in damper passes through when generation relative motion vibrated between vehicle body and vehicle bridge
Move up and down, the damping oil in snubber cavity just repeatedly by hole to be flowed into another from chamber intracavitary, at this point, passing through
The intermolecular friction of friction and oil liquid between hole wall and oil liquid forms damping force to vibration, to realize damping purpose.
In existing suspension system, the effect of damper is particularly significant, and dust-proof for damper also shows very necessary, and one
As damper dust cover will be installed.Damper dust-proof cover one kind in existing technology is Open architecture, is had with damper outer cylinder
Certain gap, and such structure have dust or silt by the lower openings of dust cover be deposited on damper oil sealing and
On piston rod, the scuffing of piston rod and oil sealing is caused to lead to oil leak, to reduce the service life, another is the compression with fold
Formula, temperature is higher at fold in telescopic process repeatedly is prone to wear rupture for this kind of dust cover, and service life is not grown.
Utility model content
The purpose of the utility model is to provide a kind of good dustproof effect dampers with long service life.
In order to realize above-mentioned purpose of utility model, the following technical solution that a kind of dustproof vibration-damper of the utility model uses:
A kind of dustproof vibration-damper, the other end including the connection of working cylinder, the piston being set in working cylinder, one end and piston
The piston rod that working cylinder is connect with upper bracket is stretched out, circular ring shape base, the pedestal inner circle half are coated at the top of the working cylinder
Diameter is matched with piston rod, and the base upper surface is provided with round ring boss one, and it is recessed that the boss one is provided centrally with circular ring shape
Slot one, one bottom centre of groove are provided with circular ring shape inserting groove, are plugged in the inserting groove and the matched circle of inserting groove
Annular isolation plate, the upper bracket are coated with circular ring shape elastic support, and the elastic support inner peripheral surface is provided centrally with and upper branch
The annular groove of seat cooperation, the elastic support lower surface are provided with the boss two cooperated with groove one, and the boss two is provided with
With the groove two of isolation board cooperation, the boss two is plugged in groove one, and groove two is socketed on isolation board, the height of the boss two
The depth of degree and groove one is all larger than piston rod maximum displacement distance.Boss two moves reciprocatingly in groove one with piston rod,
W-shaped dust-proof channel is formed between boss one, boss two and isolation board, is effectively avoided dust or sandy soil from entering and is deposited on damper
Oil sealing and piston rod on, isolation board and groove one are to be detachably connected, easy to clean or isolation board that replacement rapid wear is easily dirty.
The grafting groove sidewall is provided with arc groove, and the isolation board bottom is provided with convex with the arc of arc groove cooperation
It rises.Isolation board is connected in inserting groove, is not easy to fall off because of vibration.
The isolation board inner peripheral surface and outer peripheral surface are respectively arranged with felt.Felt wearability is good, shock resistance is good, moreover it is possible to play
The effect of noise reduction.
Compared with prior art, the utility model has the beneficial effects that: good dustproof effect, long service life.
