Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

As shown in FIGS. 1-2, the utility model discloses a symmetrical rim, which comprises a symmetrical rim body 10. The rim body 10 has a well bottom 11, two bead seats 12 and two beads 13. The groove bottom 11 is arranged symmetrically with respect to the symmetric plane of the rim body 10, the two bead seats 12 are arranged symmetrically with respect to the symmetric plane of the rim body 10 on both sides of the groove bottom 11, and the two beads 13 are arranged symmetrically with respect to the symmetric plane of the rim body 10 on the outer sides of the bead seats 12. In order to secure the strength of the rim body 10, the bead seat 12 has a plurality of bent portions 121. On the basis of guaranteeing the intensity of rim body 10, simplify the structure of rim body 10 as far as possible to do benefit to the processing drawing of patterns, so the quantity of portion 121 of bending sets up three at most, and the interior angle B of portion 121 of bending is not less than 145, guarantees the smooth transition of buckling, does benefit to the shaping manufacturing.

In order to allow the rim body 10 and the spoke 30 to establish an offset distance having a larger threshold value, it is required that the width C of the well bottom 11 is greater than the width D5% of the rim body 10, preferably, the width C of the well bottom 11 is greater than the width D20% of the rim body 10, and in order to secure the strength of the rim body 10, it is further preferable that the width C of the well bottom 11 is greater than the width D20 to 40% of the rim body 10, and it is further preferable that the width C of the well bottom 11 is greater than the width D26 to 35% of the rim body 10, and the width C of the well bottom 11 is controlled within this range, and the adjustment threshold value of the strength of the rim body 10 and the offset distance between the rim body 10 and the spoke 30 is satisfied. In addition, to fit a tire of conventional tire width, the width C of the groove bottom 11 is typically between 18-91 mm. The above definition ensures that the contact surface of the groove bottom 11 with the spoke 30 is sufficient and has a large offset adjustment threshold. In order to further enhance the strength of the rim body 10 and ensure the stable installation of the tire, the depth E of the groove bottom 11 is required to be 24-30 mm. In the case of using an air tube for a wheel, the valve 20 can be easily and reliably mounted by the above setting because the rim body 10 has a symmetrical structure, the valve 20 can be mounted on either side, the valve hole 14 is provided in either one or both of the bead seats 12, and the valve hole 14 is provided near the groove bottom 11, and preferably, the valve hole 14 is provided between the two bent portions 121.

Based on the same inventive concept, the utility model also discloses a hub, which comprises the spoke 30 and the symmetrical rim, wherein the edge of the spoke 30 is fixedly connected with the groove bottom 11, and the welding is optimized. The groove bottom 11 not only can increase the range of the contact surface between the spoke 30 and the rim body 10 during assembly, has more margin to ensure full contact with the spoke 30, but also can provide the possibility of assembling with various offset distances, as shown in fig. 3-5, the offset distances, namely the distance between the center plane of the rim body and the spoke mounting surface, are respectively corresponding to three hubs with different offset distances, and are marked as P in the figures. In addition, the convenience and the efficiency of the installation of the wheel hub can be improved, the product performance is improved, and the contradiction of the unfavorable welding of the corner when the traditional wheel rim is assembled is improved.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
