Description
Technical field
The utility model relates to motorcycle part, particularly a kind of oil cylinder of motor bike.
Background technology
Motor bike oil cylinder is generally made up of cylinder body and the cylinder cap be arranged on cylinder body top, opens cylinder cap, can refuel in oil cylinder.
When driving, gasoline there will be and rocks in oil cylinder, and in order to avoid gasoline is revealed between cylinder cap and cylinder body connecting portion, prior art have employed and arrange rubber seal between cylinder cap and cylinder body.But due to seal ring easily aging, and the contact of gasoline and seal ring can accelerate the aging process of seal ring, and therefore the problem of cylinder cap place leakage of oil still often can appear in existing motor bike oil cylinder.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of Anti-leakage type motor bike oil cylinder, to solve the problem that the leakage of oil of cylinder cap place and the easy aged deterioration of cylinder cap place seal ring easily appear in existing oil cylinder.
The utility model Anti-leakage type motor bike oil cylinder, comprise cylinder body and cylinder cap, described cylinder body top is provided with oil filling port, also comprise the seal receptacle being welded on cylinder body oiling oral area, described seal receptacle is provided with and the axle journal of inner hole of cylinder cover screw thread fit and the seal ring that coordinates with cylinder cap end face, there is in the middle part of seal receptacle the fuel feed hole just right with oil filling port; Described cylinder cap is provided with the gear oil column with fuel feed hole free-running fit on seal receptacle, described gear oil column lower end is arranged in cylinder wall, and the end face of described seal receptacle is provided with annular oil resevoir.
Further, oil suction felt is also provided with in described annular oil resevoir.
Further, described cylinder cap is provided with the annular boss with annular oil resevoir free-running fit.
Further, the gap width between described gear oil column and fuel feed hole is 0.10 ~ 0.20mm.
The beneficial effects of the utility model:
The utility model Anti-leakage type motor bike oil cylinder, it by arranging gear oil column on cylinder cap, and under the barrier effect of gear oil column, in-oil cylinder fuel oil is not easy to enter the gap between gear oil column and seal receptacle; And because the gap between gear oil column and seal receptacle is less, and the axial length in gap is longer between seal receptacle and gear oil column, even if there is a small amount of fuel oil to enter the tolerance clearance of keeping off between oil column and seal receptacle, these fuel oils also more difficult rising along tolerance clearance arrive cylinder cap and seal receptacle end face auxiliary section; Even and if having a small amount of fuel oil by cylinder cap and seal receptacle end face auxiliary section, these fuel oils can be stored in the annular oil resevoir on seal receptacle end face, and can not contact with seal ring; This Anti-leakage type motor bike oil cylinder has multiple-sealed structure, the fuel oil rocked in driving conditions can be avoided to contact with seal ring through gap between casing with case lid, can stop oil cylinder leakage problem; And due to seal ring not with fuel contacts, its aged deterioration time can extend greatly.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of Anti-leakage type motor bike oil cylinder.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment Anti-leakage type motor bike oil cylinder, comprise cylinder body 1 and cylinder cap 2, described cylinder body top is provided with oil filling port, also comprise the seal receptacle 3 being welded on cylinder body oiling oral area, described seal receptacle is provided with and the axle journal of inner hole of cylinder cover screw thread fit and the seal ring 4 that coordinates with cylinder cap end face, there is in the middle part of seal receptacle the fuel feed hole just right with oil filling port; Described cylinder cap is provided with the gear oil column 5 with fuel feed hole free-running fit on seal receptacle, described gear oil column lower end is arranged in cylinder wall; The end face of described seal receptacle is provided with annular oil resevoir 6.In the present embodiment, gap width between described gear oil column and fuel feed hole is 0.10mm, certainly in a particular embodiment, gap width between gear oil column and fuel feed hole also can be other value within the scope of 0.10 ~ 0.20mm, gap width is less, sealing property is better, and certain manufacture difficulty is also larger, can specifically select as required in a particular embodiment.
The present embodiment Anti-leakage type motor bike oil cylinder, it by arranging gear oil column on cylinder cap, and under the barrier effect of gear oil column, in-oil cylinder fuel oil is not easy to enter the gap between gear oil column and seal receptacle; And because the gap on gear oil column and seal receptacle between fuel feed hole is less, and the axial length in gap is longer between seal receptacle and fuel feed hole, even if there is a small amount of fuel oil to enter the tolerance clearance of keeping off between oil column and seal receptacle, these fuel oils also more difficult rising along tolerance clearance arrive cylinder cap and seal receptacle end face auxiliary section; Even and if having a small amount of fuel oil by cylinder cap and seal receptacle end face auxiliary section, these fuel oils can be stored in the annular oil resevoir on seal receptacle end face, and can not contact with seal ring; From Such analysis known Anti-leakage type motor bike oil cylinder, there is multiple-sealed structure, driving conditions IFO intermediate fuel oil can be avoided directly to contact with seal ring, oil cylinder leakage problem can be stopped; And due to seal ring not with fuel contacts, its aged deterioration time can extend greatly.
As the improvement to the present embodiment, also be provided with oil suction felt 7 in described annular oil resevoir, after having a small amount of fuel oil to enter annular oil resevoir, oil suction felt 7 can be adsorbed, fuel oil when driving can be avoided to rock in annular oil resevoir, discharged by evaporation mode by the fuel oil energy adsorbed.
As the improvement to the present embodiment, described cylinder cap is provided with the annular boss 8 with annular oil resevoir free-running fit, the fuel oil in annular oil resevoir can be stoped to enter into end clearance between cylinder cap and seal receptacle, sealing property can be improved further.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
