Abstract

A dustproof device of a shock absorber comprises a dustproof hood cover and a dustproof cylinder, wherein the dustproof hood cover covers the upper end of the dustproof cylinder and is connected with the dustproof cylinder in a sealing way; the upper end of the dustproof hood cover is connected with a hanging ring; the lower end of the dustproof hood cover is connected with a connecting rod of the shock absorber; n heat radiation holes are arranged in the top surface of the dustproof hood cover; and the value of n is any integer from 2 to 8 generally. As for the dustproof device of the shock absorber, the dustproof hood cover is provided with the heat radiation holes, and convection can be formed between the dustproof cylinder and external air through the through holes of the dustproof hood cover regardless of whether a connecting rod assembly moves vertically or rest relatively, so that the temperature in the dustproof cylinder can be lowered rapidly and the temperature of the shock absorber is further lowered. For the dustproof device of the shock absorber, the structural type of the original dustproof hood cover and the dustproof cylinder is not changed, the structure is simple and the processing is convenient; the heat radiation holes are arranged at the top end of the dustproof hood cover and the dustproof effect is not influenced; and the dustproof device is economical and practical.

Description

The vibration damper dust guard

Technical field

The utility model relates to a kind of ride-control annex, especially a kind of vibration damper dust guard.

Background technique

The present ride-control that uses, in order to stop foreign matters such as muddy water on the road surface to enter the motive sealing position of vibration damper, the general dust shroud that is connected with suspension ring and the dust proof tube of all designing is as dust guard, there is following deficiency in this type of dust guard: when installing and using, dust proof tube will block the over half of vibration damper urceolus, because of the upper end of dust shroud seals, the heat radiation of vibration damper is restricted, make vibration damper interior oil temperature too high, can make the oil sealing sclerosis when serious, cause the sealing effect variation and leakage of oil takes place, reduce the vibration damper life-span.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of simple in structure, easy to process, good heat dissipation effect, economical and practical vibration damper dust guard, to overcome the existing above-mentioned deficiency of prior art.

The technological scheme that solves the problems of the technologies described above is: a kind of vibration damper dust guard, comprise dust shroud and dust proof tube, dust shroud covers on the upper end of dust proof tube and is tightly connected with dust proof tube, have n radiation hole on the end face of described dust shroud, the value of said n is generally the arbitrary integer between 2～8.

Its further technological scheme is: the shape of described radiation hole or for circular or for oval or for square.

Because adopt technique scheme, the vibration damper dust guard of the utility model has following beneficial effect:

1, because of having radiation hole on the vibration damper dust guard dust shroud, can make the no longer sealing of connecting rod sub-assembly upper end with external communications, when vibration damper is worked, connecting rod, suspension ring, dust shroud and dust proof tube move up and down, air-flow can produce convection current from radiation hole on the dust shroud and ambient air, hot air in the dust proof tube is exchanged away, thereby reduce the vibration damper inside temperature.When vibration damper is static relatively, an angle turns forward when installing because of vibration damper, radiation hole on the dust shroud also turns forward, the dust proof tube lower end after, when car travels with certain speed, cool ambient air flows in the dust proof tube from the radiation hole on the dust shroud, and the hot air in the dust proof tube down flows out from the dust proof tube lower end, thereby reduces the temperature of vibration damper.

2, the vibration damper dust guard of the utility model does not change original dust shroud and dust proof tube structural type, and is simple in structure, easy to process, and radiation hole is opened the top at dust shroud, do not influence dustproof effect, economical and practical.

Below, the technical characteristics to the vibration damper dust guard of the utility model is further described in conjunction with the accompanying drawings and embodiments.

Description of drawings

Fig. 1: the vibration damper dust guard structural representation of the utility model;

The plan view of Fig. 2: Fig. 1;

Fig. 3: the vibration damper dust guard user mode schematic representation of the utility model.

Among the figure:

A-connecting rod ASSY, B-fuel tank assembly, C-cylinder barrel assembly;

1-dust proof tube, 2-dust shroud, 21-radiation hole, 22-pilot hole, 3-suspension ring, 4-connecting rod.

Embodiment

A kind of vibration damper dust guard comprises dust shroud 2 and dust proof tube 1, and dust shroud covers on the upper end of dust proof tube and is tightly connected with dust proof tube, has 4 radiation holes 21 on the end face of described dust shroud, radiation hole be shaped as circle.

As the conversion of the foregoing description, the radiation hole of opening on the end face of described dust shroud can be n, and the value of n is generally the arbitrary integer between 2～8; The shape of described radiation hole also can be square or is other polygonals.

During installation, the dust proof tube 1 of this dust guard is covered on the damper linking member assembly A, the pilot hole 22 of dust shroud packs into connecting rod 4 upper ends of connecting rod ASSY and fixes with its welding, and the upper end of dust shroud 2 and suspension ring 3 welding are fixing, as shown in Figure 3.

Working principle:

Vibration damper complement comprises connecting rod ASSY A, fuel tank assembly B, cylinder barrel assembly C, when vibration damper complement compresses, connecting rod ASSY A moves down, and cool ambient air flows in the dust proof tube from the dust proof tube lower end, and the hot air in the dust proof tube up flows out by the radiation hole on the dust shroud; When vibration damper complement stretched, connecting rod ASSY A up moved, and cool ambient air flows in the dust proof tube from the end radiation hole on the dust shroud, and the hot air in the dust proof tube down flows out from the dust proof tube lower end; When vibration damper is static relatively, an angle turns forward when installing because of vibration damper, radiation hole on the dust shroud also turns forward, the dust proof tube lower end after, when car travels with certain speed, produce air-flow and flow to the rear end from front end, cool ambient air flows in the dust proof tube from the radiation hole on the dust shroud, and the hot air in the dust proof tube down flows out from the dust proof tube lower end; Therefore,, reduce the temperature in the dust proof tube fast no matter connecting rod ASSY A moves up and down or be in when static relatively can form convection current by dust shroud through hole and ambient air, thus the temperature of reduction vibration damper.
