Description

Technical Field

[0001] The present application relates to the technical field of wheels, and in particular to a wheel and a wheel and tire assembly with an inner tube. Background Art

[0002] There are two types of automobile wheel and tire assemblies, one is a tubeless wheel and tire assembly, and the other is a tube wheel and tire assembly. In the tube wheel and tire assembly, the valve is fixedly connected to the tire inner tube, and the valve passes through the wheel valve hole for assembly. Generally, a valve clamp is used to fix the position of the valve, one end of the valve clamp fixes the valve and the other end is connected to the wheel. For example, CN205553824U, CN207510168U and CN202319767U respectively design valve clamps of different shapes.

[0003] In the prior art, the valve stem clamp has the problem of poor assembly or low assembly precision, which reduces the position precision of the valve stem, causing the valve stem to interfere with the brake or the gap is too small. How to solve the above technical problems is what the technicians in this field need to consider. Summary of the invention

[0004] The present application provides a wheel and a tube-shaped wheel and tire assembly to solve the problem of how to improve the valve position accuracy after the tube-shaped tire and the steel wheel are assembled.

[0005] The first aspect of the embodiment of the present application provides a wheel, comprising a rim and a valve fixing portion. The rim is provided with a valve groove, and the valve groove is used to pass the valve. The valve fixing portion is provided at the periphery of the valve groove, the valve fixing portion is integrally connected to the rim, and the valve fixing portion is used to limit the position of the valve on the rim.

[0006] Compared with the prior art, the wheel provided by the present application sets the valve fixing part at the periphery of the valve groove to reduce the length of the valve fixing part, which is conducive to reducing the deformation of the valve fixing part; the wheel connects the valve fixing part with the rim as a whole to reduce the assembly work of the valve fixing part and the rim, prevents the valve fixing part from being poorly assembled or having low assembly accuracy, and prevents the valve fixing part from falling off, so as to improve the position accuracy of the valve. At the same time, the wheel also reduces the number of parts by connecting the valve fixing part with the rim as a whole, thereby reducing production costs.

[0007] In a possible implementation manner, the valve fixing portion and the wheel rim are formed by stamping.

[0008] In mass production, the dimensional accuracy of stamped wheel products is highly consistent, which is beneficial to the consistency of valve assembly operations and improves the positioning accuracy of the valves.

[0009] In a possible implementation manner, the valve groove is an elongated hole, and a length L1 of the valve groove ranges from 39 mm to 100 mm.

[0010] The opening length of the valve stem groove is along the length direction of the valve stem, so that the valve stem can pass through the valve stem groove during assembly, thereby improving the position accuracy of the valve stem.

[0011] In a possible implementation manner, the valve fixing portion extends from a periphery of the valve groove along a length direction of the valve.

[0012] The valve fixing portion extends along the length direction of the valve, so that the valve fixing portion fixes the valve in the radial direction, reduces the displacement of the valve in the radial direction, and improves the position accuracy of the valve.

[0013] In a possible implementation manner, the length of the valve groove is L1, and the length L2 of the extension portion of the valve fixing portion ranges from 10 mm to 1 / 2 L1.

[0014] If the extended length of the valve fixing part is less than 10mm, it is difficult to fix the valve; if the extended length of the valve fixing part is greater than 1 / 2 of the length of the valve groove, the extended part of the valve fixing part will easily block the valve from passing through during the assembly process. Therefore, the extended length L2 of the valve fixing part is in the range of 10mm to 1 / 2L1, which is conducive to assembling and fixing the valve and improving the positioning accuracy of the valve.

[0015] In a possible implementation manner, a surface of the valve fixing portion close to the valve is radially fitted with the valve.

[0016] The angle of the surface of the valve fixing part close to the valve is the same as the design angle of the valve, and the valve fixing part fits with the valve along the radial direction so that the valve fixing part fixes the valve and reduces the movement of the valve in the radial direction, thereby improving the position accuracy of the valve and controlling the clearance between the valve and the brake.

[0017] In a possible implementation manner, the inclination angle α of the extension portion of the valve fixing portion is the same as the angle of the valve, and the height L3 of the bent portion of the valve fixing portion is the same as the protruding height of the valve.

[0018] In a possible implementation manner, a gap L4 between the air valve and the bent portion of the air valve fixing portion along the horizontal direction is not less than 3.25 mm.

[0019] In a possible implementation manner, the end of the valve nozzle is spaced apart from the rim, thereby reducing friction between the valve nozzle and the rim during operation of the wheel, which is beneficial to improving the position accuracy of the valve nozzle.

[0020] In a possible implementation manner, a spoke valve hole groove is provided on a surface of the rim close to the end of the valve, and a distance between the spoke valve hole groove and the end of the valve is not less than 2 mm.

[0021] A second aspect of the embodiment of the present application provides a tire assembly with an inner tube, comprising an inner tube and a valve connected to each other. The valve passes through a valve groove of the wheel and fits with the valve fixing portion along a radial direction. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0029] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0030] Example See also Figures 1 to 4 As shown, this embodiment provides a wheel 1, including a rim 11 and a valve fixing portion 12. The rim 11 is provided with a valve groove 111, and the valve groove 111 is used to pass the valve 21. The valve fixing portion 12 is arranged at the periphery of the valve groove 111, and the valve fixing portion 12 is integrally connected with the rim 11, and the valve fixing portion 12 is used to limit the position of the valve 21 located on the rim 11.

[0031] The wheel 1 provided by the present application arranges the valve fixing part 12 at the periphery of the valve groove 111 to reduce the length of the valve fixing part 12, which is beneficial to reducing the deformation of the valve fixing part 12; the wheel 1 connects the valve fixing part 12 with the rim 11 as a whole to reduce the assembly work of the valve fixing part 12 and the rim 11, prevents the valve fixing part 12 from being poorly assembled or having low assembly accuracy, and prevents the valve fixing part 12 from falling off, so as to improve the position accuracy of the valve 21. At the same time, the wheel 1 also reduces the number of parts by connecting the valve fixing part 12 with the rim 11 as a whole, thereby reducing production costs.

[0032] In this embodiment, the valve fixing portion 12 and the rim 11 can be manufactured by stamping, injection molding or 3D printing. This embodiment is not limited by the manufacturing method of the wheel 1. As long as the valve fixing portion 12 and the rim 11 are integrally connected, it is beneficial to improve the position accuracy of the valve fixing portion 12 and the rim 11, thereby improving the position accuracy of the valve 21 and reducing the interference between the valve 21 and the brake and the small gap.

[0033] In a possible implementation manner, the valve fixing portion 12 and the wheel rim 11 are formed by stamping.

[0034] In this embodiment, the valve fixing portion 12 is made of the excess material of the valve groove 111 punched out of the wheel 1. In mass production of wheels 1, the stamped valve fixing portion 12 has a high consistency in dimensional accuracy, which is conducive to the consistency of the valve 21 assembly operation, thereby improving the position accuracy of the valve 21 assembled on the wheel 1.

[0035] In a possible implementation manner, the valve groove 111 is a long hole, and the opening width of the valve groove 111 is greater than the outer diameter of the valve 21 , so that the valve 21 can pass through the valve groove 111 .

[0036] In this embodiment, the opening length of the valve groove 111 extends along the length direction of the valve 21, so that the valve 21 can pass through the valve groove 111 during assembly, reducing the assembly interference between the valve 21 and the wheel 1, thereby improving the positioning accuracy of the valve 21.

[0037] In a possible implementation manner, the length L1 of the valve groove 111 ranges from 39 mm to 100 mm.

[0038] In this embodiment, the length of the valve groove 111 is selected to be of a suitable size according to the size of the valve 21 and the size of the wheel 1, and this embodiment is not limited to a specific size. The length L1 of the valve groove 111 ranges from 39 mm to 100 mm, so that the valve 21 can pass through the valve groove 111 when the inner tube wheel tire assembly 2 is assembled.

[0039] In a possible implementation manner, the valve fixing portion 12 extends from the periphery of the valve groove 111 along the length direction of the valve 21 .

[0040] In this embodiment, the valve 21 passes through the valve groove 111 from the inner tube 212 and protrudes to the side of the rim 11 opposite to the inner tube 212 , and the valve 21 protrudes out of the valve groove 111 .

[0041] The valve fixing portion 12 extends along the length direction of the valve 21, and the valve fixing portion 12 fixes the valve 21 along the radial direction 13, reduces the displacement of the valve 21 along the radial direction 13, and improves the position accuracy of the valve 21. The valve fixing portion 12 includes a bending portion 121 and an extension portion 122. One end of the bending portion 121 is connected to the periphery of the valve groove 111, and the other end is connected to the extension portion 122. The bending portion 121 protrudes in a direction perpendicular to the surface of the rim 11, and the extension portion 122 extends along the length direction of the valve groove 111. The extension portion 122 corresponds to the valve 21 along the radial direction 13. The bending portion 121 is spaced apart from the valve 21, and the protruding distance of the bending portion 121 makes the surface of the extension portion 122 fit the valve 21 along the radial direction 13, so that the extension portion 122 fixes the position of the valve 21 along the radial direction 13, and improves the position accuracy of the valve 21.

[0042] In a possible implementation manner, the length of the valve groove 111 is L1, and the length L2 of the extension portion of the valve fixing portion 12 ranges from 10 mm to 1 / 2 L1.

[0043] In this embodiment, if the length of the extension portion 122 of the valve fixing portion 12 is less than 10 mm, it is difficult to fix the valve 21; if the length of the extension portion 122 of the valve fixing portion 12 is greater than 1 / 2 of the length of the valve groove 111, then during the assembly process, the extension portion 122 of the valve fixing portion 12 will easily block the valve 21 from passing through. Therefore, the length L2 of the extension portion of the valve fixing portion 12 is in the range of 10 mm to 1 / 2L1, which is conducive to assembling and fixing the valve 21 and improving the positioning accuracy of the valve 21.

[0044] In a possible implementation manner, a surface of the valve fixing portion 12 close to the valve 21 is in contact with the valve 21 along the radial direction 13 .

[0045] In this embodiment, the angle of the surface of the valve fixing portion 12 close to the valve 21 is the same as the design angle of the valve 21, and the valve fixing portion 12 fits with the valve 21 along the radial direction 13, so that the valve fixing portion 12 fixes the valve 21 and reduces the movement of the valve 21 in the radial direction 13, thereby improving the position accuracy of the valve 21 and controlling the gap between the valve 21 and the brake.

[0046] In a possible implementation manner, the inclination angle α of the extension portion 122 of the valve fixing portion 12 is the same as that of the valve 21 , and the height L3 of the bent portion 121 of the valve fixing portion 12 is the same as the protruding height of the valve 21 .

[0047] In this embodiment, the inclination angle α of the extension portion 122 of the valve fixing portion 12 is the same as the design angle of the valve 21, and the height L3 of the bent portion is required to ensure that the long side of the valve 21 fits the wheel and tire assembly after being inflated (the free state of the valve tube after assembly is completed), so that the valve fixing portion 12 can stably fix the valve 21, prevent the valve 21 from moving in the radial direction, and control the gap between the valve 21 and the brake.

[0048] In a possible implementation manner, a gap L4 between the air valve 21 and the bent portion 121 of the air valve fixing portion 12 along the horizontal direction is not less than 3.25 mm.

[0049] The air valve 21 is spaced apart from the bent portion 121 of the air valve fixing portion 12 , thereby facilitating the air valve 21 to enter the air valve fixing portion 12 through the air valve groove 111 during assembly.

[0050] In a possible implementation manner, the end of the valve 21 is spaced apart from the rim 11 .

[0051] In this embodiment, the end of the valve 21 is spaced apart from the rim 11 , thereby reducing the friction between the valve 21 and the rim 11 and causing displacement of the wheel 2 during operation, which is beneficial to improving the position accuracy of the valve 21 .

[0052] In a possible implementation manner, a spoke valve hole groove 112 is provided on the surface of the rim 11 close to the end of the valve 21 , and a distance L5 between the spoke valve hole groove 112 and the end of the valve 21 is not less than 2 mm.

[0053] In this embodiment, the spoke valve hole groove 112 is a groove, and the surface of the rim 11 is sunken to form the spoke valve hole groove 112 to reduce the friction between the valve mouth 21 and the rim 11 , which is beneficial to improve the position accuracy of the valve mouth 21 .

[0054] The second aspect of the embodiment of the present application provides a tire assembly 2 with a tube, comprising a connected inner tube 22 and a valve 21. The valve 21 passes through a valve groove 111 and fits with a valve fixing portion 12 along a radial direction 13.

[0055] In this embodiment, the inner tube wheel tire assembly 2 includes an inner tube 22 and a valve 21 connected to each other. The valve 21 passes through the valve groove 111 of the wheel 1 and fits with the valve fixing portion 12 along the radial direction 13. The wheel 1 sets the valve fixing portion 12 at the periphery of the valve groove 111 to reduce the length of the valve fixing portion 12, which is conducive to reducing the deformation of the valve fixing portion 12. The wheel 1 is integrally connected with the rim 11 through the valve fixing portion 12, thereby reducing the assembly work of the valve fixing portion 12 and the rim 11, so as to improve the position accuracy of the valve 21, control the gap between the valve 21 and the brake, and reduce the interference between the valve 21 and the brake and the situation where the gap is too small.

[0056] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
