Abstract
The utility model belongs to the vehicle part field which relates to the improvement of the connection joint of the vehicle power steering device. The utility model is a stepped sleeve and is characterized in that the sealing end where a joint is jointed with the inner conical surface of an oil pipe nozzle is a spherical surface whose radius is R; R equals to 4 mm to 20 mm. the utility model can guarantee the sealing performance of the joint surface of the joint and the oil pipe nozzle when the joint and the oil pipe nozzle are not coaxial so that the sealing performance of the vehicle power steering device is greatly improved and the oil-leakage of the vehicle power steering device is avoided.
Description
Technical field
The utility model belongs to the automobile component field, relates to the improvement to the automobile power steering coupling head.
Background technique
At present, the automobile power steering coupling head be widely used in all kinds of light, in, in the heavy-duty car direction converter, the structure of existing automobile power steering coupling head is referring to Fig. 1, the sealing relationship of it and oil pipe mouth is seen Fig. 2.Coupling head is a stepped shape sleeve pipe that has the center through hole, and the connecting end diameter of it and automobile power steering filler opening or return opening is little, and the sealed end diameter of fitting with oil pipe mouth inner conical surface is big.The sealing surface of existing coupling head and oil pipe mouth is a conical surface, and the desirable contact segment of itself and oil pipe mouth is a circle.The coaxality of this structural requirement coupling head and oil pipe mouth is very high, as coupling head and oil pipe mouth disalignment, the gap will occur in the joint place, causes the phenomenon of automobile power steering product leakage of oil.In case the generation leakage of oil, whole product must be pulled down from automobile, and the return-to-factory maintenance causes very big loss.
Summary of the invention
The purpose of this utility model is: do not require coupling head and oil pipe mouth disalignment even propose a kind of coaxality to coupling head and oil pipe mouth, still can guarantee the automobile power steering coupling head of coupling head and oil pipe mouth faying surface sealability.
The technical solution of the utility model is: a kind of automobile power steering coupling head, it is a stepped shape sleeve pipe that has the center through hole, the connecting end diameter of it and automobile power steering filler opening or return opening is little, the sealed end diameter of fitting with oil pipe mouth inner conical surface is big, it is characterized in that, the sealed end that coupling head and oil pipe mouth inner conical surface are fitted is that radius is the sphere of R, R=4～20mm.
The utility model has the advantages that: when coupling head and oil pipe mouth disalignment, still can guarantee the sealability of coupling head and oil pipe mouth faying surface, thereby improved the sealability of automobile power steering greatly, avoided the phenomenon of automobile power steering product leakage of oil.Simultaneously,, greatly reduce requirement, reduced cost part processing precision and assembly precision because the coaxality of coupling head and oil pipe mouth is not almost had any requirement.

Fig. 2 is existing automobile power steering coupling head and oil pipe mouth mated condition schematic representation.
Fig. 3 is a structural representation of the present utility model.
Fig. 4 is the utility model coupling head and oil pipe mouth mated condition schematic representation.
Fig. 5 is that the spherical radius R and the oil pipe mouth calculation of parameter of the utility model coupling head concerns schematic representation.
Embodiment
Below the utility model is described in further details.Referring to Fig. 3,4, automobile power steering coupling head of the present utility model, it is a stepped shape sleeve pipe that has the center through hole, the connecting end diameter of it and automobile power steering filler opening or return opening is little, the sealed end diameter of fitting with oil pipe mouth inner conical surface is big, it is characterized in that, the sealed end that coupling head and oil pipe mouth inner conical surface are fitted is that radius is the sphere of R, R=4～20mm, the size relationship of itself and oil pipe mouth is:
X is a contact coefficient, generally gets: 0.3～0.5.Referring to Fig. 5, Φ A is the maximum diameter of oil pipe mouth inner conical surface, and B is the axial length of oil pipe mouth inner conical surface, and a is the cone angle of oil pipe mouth inner conical surface.
Because the sealed end that the utility model and oil pipe mouth inner conical surface are fitted is that radius is the sphere of R, so when coupling head and oil pipe mouth disalignment, both surface of contact still are the identical circle of diameter, the gap can not occur, have avoided the phenomenon of leakage of oil effectively.
Embodiment 1, and the oil pipe mouth inner conical surface maximum diameter that coupling head cooperated is A=10.4mm, contact range width B=1.4, angle a=90 °, contact coefficient x=0.4, and the spherical radius R of the sealed end that coupling head and oil pipe mouth inner conical surface are fitted is 6.6mm.
Embodiment 2, and the oil pipe mouth inner conical surface maximum diameter that coupling head cooperated is A=15mm, contact range width B=3, angle a=86 °, contact coefficient x=0.4, and the spherical radius R of the sealed end that coupling head and oil pipe mouth inner conical surface are fitted is 11.8mm.
Embodiment 3, and the oil pipe mouth inner conical surface maximum diameter that coupling head cooperated is A=30mm, contact range width B=5, angle a=90 °, contact coefficient x=0.4, and the spherical radius R of the sealed end that coupling head and oil pipe mouth inner conical surface are fitted is 18.7mm.
