Preferably, described alar part from the end be connected with described interconnecting gangway downward-sloping 3 ° ~ 10 °.Alar part is downward-sloping, can improve the seal degree between sealing member, tire and wheel rim, thus improves the sealing property of tire.
Preferably, described alar part from the end be connected with described interconnecting gangway downward-sloping 5 °.Observed data shows, during downward-sloping 5 ° of alar part, tire seal degree is best.
Preferably, described first groove is U-type groove, and described second groove is V-type groove, and the second groove described in two is symmetrically distributed in the both sides of described first groove, and described salient is that V-type is protruded.First groove is U-type groove, is easy to processing, meanwhile, has longer binding face between itself and sealing member, contributes to improving sealing property.Second groove and salient are V-type groove, have both been easy to processing, are also easy to install, and interference fit between the two contributes to the sealing property improving wheel.
Preferably, the angle of the V-type groove of described second groove is 15 ° ~ 25 °, and the angle that the V-type of described salient is protruded is 30 ° ~ 50 °.Observed data shows, when adopting aforementioned angular, the second groove and salient have degree of laminating preferably, contributes to improving sealing property.
Preferably, the angle of the V-type groove of described second groove is 20 °, and the angle that the V-type of described salient is protruded is 40 °.Observed data shows, when the second groove and salient adopt aforementioned angular respectively, the sealing property of tire is best.
Positive progressive effect of the present utility model is: the airtight tire space of the utility model wheel has good sealing property, and period of service is longer, and its sealing property can be become better and better; In addition, wheel of the present utility model have cost low, make processing and easy for installation and change parts advantages easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
Fig. 2 is the structural representation of the wheel rim of the utility model preferred embodiment.
Fig. 3 is the structural representation that the sealing member of the utility model preferred embodiment fits in wheel rim.
Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of spoke type inner tube-free wheel, it comprises tire 1, wheel rim 2 and wheel hub, wheel rim 2 is connected by multiple spoke 4 with wheel hub, tire 1 is sheathed on wheel rim 2, wheel rim 2 is fitted with sealing member 3, the centre of wheel rim 2 is provided with the first groove 21, the both sides of the first groove 21 are respectively provided with one second groove 22, sealing member 3 comprises body 31 and is positioned at the alar part 32 at two ends of body 31, the below of each alar part 32 is respectively provided with salient 33, body 31 fits in the first groove 21, salient 33 and the second groove 22 interference fit, alar part 32 is embedded between tire 1 and wheel rim 2.
The material of sealing member generally adopts rubber, has certain elasticity, is generally rubber ring.During installation, sealing member is sheathed on wheel hub, then by tire sleeve.Wheel rim is provided with the first groove and the second groove, and it is easy to process, and cost is also low.Therefore, wheel of the present utility model have cost low, make processing and advantage easy for installation.
Body and first groove of sealing member are fitted, under the elastic force effect of sealing member itself, salient and the second groove interference fit, be embedded in the second groove after salient is squeezed, the alar part of sealing member both sides is arranged between tyre and rim, like this, an airtight tire space 5 is formed between tire and sealing member.After inflation, airtight tire space 5 has good sealing property.
Because tire and sealing member all adopt rubber, contact portion between the two extends along with period of service, has the fusion of part.Therefore, wheel of the present utility model, its period of service is longer, and the sealing property in its airtight tire space can be become better and better, and overcomes the defect that the use sealing property more of a specified duration of existing tire existence is poorer.
When sealing member changed by needs, only sealing member need be pulled down, because sealing member is only simply fit in wheel rim, therefore, wheel of the present utility model has changes parts advantage easily.
As shown in Figure 3, sealing member 3 is provided with interconnecting gangway 34 between body 31 and alar part 32, and interconnecting gangway 34 is that arcuation is protruding.The convex role of arcuation is equivalent to the effect at the convex peak of wheel rim.The existence at the convex peak of wheel rim, can make sealing band and tire (i.e. cover tire) fit tightly better.
Alar part 32 downward-sloping 3 ° ~ 10 ° from the end be connected with interconnecting gangway 34.Observed data shows, during downward-sloping 3 ° ~ 10 ° of alar part, the sealing property in airtight tire space is better than sealing property when alar part is other angles of inclination.The different angles of getting between 3 ° ~ 10 ° for alar part leaning angle carry out sealing property experiment, and final observed data shows, when downward-sloping 5 ° of alar part, airtight tire space has best sealing property.
As shown in Figure 2, the first groove 21 can be U-type groove, and the second groove 22 can be V-type groove, and two second grooves 22 can be symmetrically distributed in the both sides of the first groove 21, and salient 33 can protrude for V-type; The angle of the V-type groove of the second groove 22 can be 20 °, and the angle that the V-type of salient 33 is protruded can be 40 °.Second groove and salient are V-type groove, have both been easy to processing, are also easy to install, and interference fit between the two contributes to the sealing property improving wheel.In addition, observed data shows, when the second groove and salient adopt 20 ° and 40 ° respectively, the sealing property of tire is best.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that this is only casehistory, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
