Abstract
The utility model relates to a kind of objective vehicle wheel side oil enveloping structure, comprise wheel hub, central siphon, semiaxis and oil sealing, central siphon is installed in wheel hub, and semiaxis is installed in central siphon endoporus, and the flange on semiaxis is connected with wheel hub end face, oil sealing is arranged between wheelboss inner hole and central siphon cylindrical.The utility model to take turns the oil seal pressing of limit sealing between passenger vehicle wheelboss inner hole and central siphon cylindrical, the lip of oil sealing inwardly, oil sealing and wheelboss inner hole and central siphon cylindrical cooperatively interact, realize sealing function, wheelboss inner hole and central siphon cylindrical itself are all machinework faces, do not need again to process, process and assemble cost can be effectively reduced compared with existing structure; In addition, oil sealing is seated in central siphon top, and when dismounting semiaxis, semiaxis does not contact with oil sealing, can not cause any damage to oil sealing, ensures oil sealing service life and quality, greatly reduces the fault rate of oil sealing.
Description
technical field:
The utility model relates to passenger vehicle mounting structure technical field, is specifically related to a kind of objective vehicle wheel side oil enveloping structure.
background technology:
As shown in Figure 1, passenger vehicle vehicle bridge axle-shaft oil seal structure is in the market all be fitted in central siphon endoporus substantially, be fitted between central siphon 101 inner hole wall and semiaxis 103, the lip of oil sealing 102 is towards in central siphon, and the periphery fitted seal that semiaxis 103 processes; This kind of structure has two shortcomings: one is complex process, and cost is high: on semiaxis 103, and the installation site of oil sealing 102 must go out an attachment face and oil sealing 102 cooperatively interacts by detailed manufacture, and this processing mode adopts ground finish mostly, and tooling cost is higher; Two is dismounting difficulties, and because semiaxis 103 itself is longer, and the outside diameter of splined section is generally greater than bar portion diameter, so easily cause oil sealing 102 to damage in the process of dismounting semiaxis 103, causes objective vehicle wheel side leakage of oil.
utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of objective vehicle wheel side oil enveloping structure, it be will the oil seal pressing of wheel limit sealing between passenger vehicle wheelboss inner hole and central siphon cylindrical, inwardly, oil sealing and wheelboss inner hole and central siphon cylindrical cooperatively interact the lip of oil sealing, realize sealing function, wheelboss inner hole and central siphon cylindrical itself are all machinework faces, do not need again to process, can effectively reduce process and assemble cost compared with existing structure; In addition, oil sealing is seated in central siphon top, and when dismounting semiaxis, semiaxis does not contact with oil sealing, can not cause any damage to oil sealing, ensures oil sealing service life and quality, greatly reduces the fault rate of oil sealing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of objective vehicle wheel side oil enveloping structure, wherein: comprise wheel hub, central siphon, semiaxis and oil sealing, central siphon is installed in wheel hub, and semiaxis is installed in central siphon endoporus, and the flange on semiaxis is connected with wheel hub end face, and oil sealing is arranged between wheelboss inner hole and central siphon cylindrical.
Further, the lip of described oil sealing is inner towards wheel hub.
Further, described oil sealing and wheelboss inner hole press-fit fixing, with hub rotation.
The beneficial effects of the utility model are:
The utility model to take turns the oil seal pressing of limit sealing between passenger vehicle wheelboss inner hole and central siphon cylindrical, the lip of oil sealing inwardly, oil sealing and wheelboss inner hole and central siphon cylindrical cooperatively interact, realize sealing function, wheelboss inner hole and central siphon cylindrical itself are all machinework faces, do not need again to process, process and assemble cost can be effectively reduced compared with existing structure; In addition, oil sealing is seated in central siphon top, and when dismounting semiaxis, semiaxis does not contact with oil sealing, can not cause any damage to oil sealing, ensures oil sealing service life and quality, greatly reduces the fault rate of oil sealing.
accompanying drawing illustrates:
Fig. 1 is existing objective vehicle wheel side sealed structural representation;
Fig. 2 is structural representation of the present utility model.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, a kind of objective vehicle wheel side oil enveloping structure, comprise wheel hub 1, central siphon 3, semiaxis 4 and oil sealing 2, central siphon 3 is installed in wheel hub 1, semiaxis 4 is installed in central siphon 3 endoporus, and the flange on semiaxis 4 is connected with wheel hub 1 end face, oil sealing 2 is arranged between wheel hub 1 endoporus and central siphon 3 cylindrical, and oil sealing 2 and wheel hub 1 endoporus press-fit fixing, rotate with wheel hub 1, the lip of oil sealing 2 is inner towards wheel hub 1, and oil sealing 2 and central siphon 3 cylindrical cooperatively interact, and realizes sealing.
Be noted that, above-described embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendment made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
