Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and more particularly, to a structural improvement of a wheel. Background Art

[0002] In the prior art, the spoke and the rim of a wheel are fixedly connected by welding. However, before welding the spoke to the rim, the rim and the spoke need to be arranged in a predetermined relative position and then welded. During this process, the two cannot be reliably locked, resulting in the spoke and the rim being displaced during the welding operation. In this way, the coaxiality of the rim and the spoke cannot be guaranteed, the installation accuracy of the spoke is reduced, and the spoke cannot provide a stable and uniform supporting effect on the rim. When the wheel is subjected to a radial load, the force on the rim is uneven, and the rim has a large deformation. As a result, when the wheel is running, the radial runout of the wheel is relatively high, resulting in a jitter phenomenon, which affects the normal running of the vehicle and even poses a threat to the life safety of the passengers. Summary of the Invention

[0003] The main object of the present invention is to provide a wheel to solve the problems in the prior art that when the spoke is welded and installed on the rim, the coaxiality of the rim and the spoke cannot be guaranteed, the installation accuracy of the spoke is reduced, the spoke cannot provide a stable and uniform supporting effect on the rim, the force on the rim is uneven when the wheel is subjected to a radial load, the rim has a large deformation, resulting in a relatively high radial runout of the wheel and a jitter phenomenon when the wheel is running, which affects the normal running of the vehicle and even poses a threat to the life safety of the passengers.

[0004] To achieve the above object, the present invention provides a wheel, including a rim and a spoke. A first positioning structure is formed on the circumference of one end of the rim in the axial direction; a second positioning structure is formed on the spoke, and the spoke is installed and positioned on the rim through the cooperation of the second positioning structure and the first positioning structure.

[0005] Further, the first positioning structure is a boss arranged along the axial direction of the rim, and the second positioning structure is a positioning hole opened on the spoke. The spoke is installed at one end of the rim in the axial direction through the insertion and cooperation of the positioning hole and the boss.

[0006] Further, the boss includes an axially limiting section and an insertion section connected in a direction away from the rim. A stop end face is formed at the connection position of the axially limiting section and the insertion section. After the insertion section is inserted into the positioning hole, the stop end face abuts against the axial inner surface of the spoke.

[0007] Further, the positioning hole is a through hole or a blind hole.

[0008] Furthermore, the cross-section of the positioning hole is adapted to the cross-sectional shape of the boss. The boss is an arc-shaped protrusion extending along the circumferential direction of the rim, or the boss is a columnar protrusion.

[0009] Furthermore, both the positioning holes and the bosses are provided in plurality and are arranged in one-to-one correspondence. The plurality of positioning holes and the plurality of bosses are arranged at intervals along the circumferential direction of the rim.

[0010] Furthermore, the positioning hole is a round hole and the boss is cylindrical.

[0011] Furthermore, the positioning hole is an annular blind hole and the boss is an annular boss continuously arranged along the circumferential direction of the rim.

[0012] Furthermore, a plurality of ventilation holes are also provided on the spoke at intervals along its circumferential direction, and the positioning holes are located on the circumferential outer side of the plurality of ventilation holes.

[0013] Furthermore, the spoke is welded to the rim, and a first weld bead structure and a second weld bead structure are formed at the connection between the two. Among them, the first weld bead structure is located between the outer wall surface of the boss and the hole wall surface of the positioning hole, and the second weld bead structure is located at the connection position between the axial inner surface of the spoke and the outer peripheral surface of the rim.

[0014] Applying the technical solution of the present invention, by optimizing the structure of the wheel, the rim has a first positioning structure, and at the same time the spoke has a second positioning structure. In this way, during the process of installing the spoke onto the rim before welding the spoke and the rim, the operator can accurately install and position the spoke onto the rim through the cooperation between the second positioning structure on the spoke and the first positioning structure on the rim, so that the relative positions of the two are locked, ensuring that the two will not shift relative to each other during the subsequent welding operation, improving the installation accuracy of the spoke, ensuring the coaxiality between the welded spoke and rim, enabling the spoke to provide a stable and uniform supporting effect for the rim, thereby ensuring that the rim is evenly stressed when the wheel is subjected to a radial load, avoiding a large deformation of the rim, ensuring that when the wheel is running, the radial runout of the wheel is within the allowable range, avoiding the wheel from shaking, and ensuring that the vehicle can run normally, thus guaranteeing the life safety of the passengers.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation on the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] In order to solve the problems in the prior art that when the spoke is welded and installed on the rim, the coaxiality of the rim and the spoke cannot be guaranteed, the installation accuracy of the spoke is reduced, resulting in the spoke being unable to provide a stable and uniform supporting effect on the rim, causing uneven stress on the rim when the wheel is subjected to a radial load, and the rim having a large deformation amount, so that when the wheel is running, the radial runout of the wheel is relatively high, resulting in a jitter phenomenon, affecting the normal running of the vehicle, and even threatening the life safety of the passengers, the present invention provides a wheel.

[0030] Embodiment 1

[0031] As Figures 1 to 6 shown, the wheel includes a rim 10 and a spoke 20. Among them, a first positioning structure is formed on the circumference of one axial end of the rim 10; a second positioning structure is formed on the spoke 20, and the spoke 20 is installed and positioned on the rim 10 through the cooperation of the second positioning structure and the first positioning structure.

[0032] By optimizing the structure of the wheel, the rim 10 has a first positioning structure, and at the same time the spoke 20 has a second positioning structure. In this way, during the process of installing the spoke 20 on the rim 10 before welding the spoke 20 and the rim 10, the operator can accurately install and position the spoke 20 on the rim 10 through the cooperation of the second positioning structure on the spoke 20 and the first positioning structure on the rim 10, so that the relative positions of the two are locked, ensuring that the two will not shift relative to each other during the subsequent welding operation, improving the installation accuracy of the spoke 20, ensuring the coaxiality between the welded spoke 20 and the rim 10, enabling the spoke 20 to provide a stable and uniform supporting effect on the rim 10, ensuring that when the wheel is running, the radial runout of the wheel is within the allowable range, avoiding the jitter phenomenon of the wheel, so as to ensure uniform stress on the rim 10 when the wheel is subjected to a radial load, avoiding a large deformation amount of the rim 10, ensuring the normal running of the vehicle, and thus ensuring the life safety of the passengers.

[0033] It should be noted that in this application, considering that the present application has respectively improved the structures of the spoke 20 and the rim 10 of the full-surface wheel, and the full-surface wheel means that after the spoke 20 is welded and installed on the rim 10, the spoke 20 plays a role in blocking the rim 10, and only the spoke 20 can be seen from the side where the spoke 20 is installed, which is beneficial to improving the appearance beauty of the wheel.

[0034] In this embodiment, as Figures 1 to 5 shown, the first positioning structure is a boss 11 arranged along the axial direction of the rim 10, and the second positioning structure is a positioning hole 21 opened on the spoke 20. The spoke 20 is installed at one end of the axial direction of the rim 10 through the plug-in fit between the positioning hole 21 and the boss 11. In this way, setting the first positioning structure as the boss 11 can reduce the processing and manufacturing difficulty of the first positioning structure, and at the same time, setting the second positioning structure as the positioning hole 21 can improve the installation adaptability with the boss 11, ensure that the spoke 20 is installed at one end of the axial direction of the rim 10 through the plug-in fit between the positioning hole 21 and the boss 11, improve the installation convenience and installation accuracy of the spoke 20, and moreover, make the rim 10 play a reliable positioning role for the spoke 20, avoiding radial shaking or circumferential rotation of the spoke 20.

[0035] As Figures 1 to 7 shown, the cross-sectional shape of the positioning hole 21 is adapted to the cross-sectional shape of the boss 11. Among them, the boss 11 is an arc-shaped protrusion extending along the circumferential direction of the rim 10, and the positioning hole 21 is a through hole. In this way, setting the boss 11 as an arc-shaped protrusion, setting the positioning hole 21 as a through hole at the same time, and the cross-sectional shape of the positioning hole 21 being adapted to the cross-sectional shape of the boss 11, when the spoke 20 is installed and positioned on the rim 10 by inserting the arc-shaped protrusion into the through hole, it is ensured that there is no relative rotation between the spoke 20 and the rim 10. In addition, the stop end face 113 formed between adjacent two bosses 11 and extending along the circumferential direction of the rim 10 abuts against the axial inner surface of the spoke 20, playing a stop and limit role for the spoke 20, thereby ensuring the installation accuracy of the spoke 20.

[0036] As Figure 6 shown, in this application, the spoke 20 is welded to the rim 10, and a first weld bead structure 100 and a second weld bead structure 200 are formed at the connection between the two. Among them, the first weld bead structure 100 is located between the outer wall surface of the boss 11 and the hole wall surface of the positioning hole 21, and the second weld bead structure 200 is located at the connection position between the axial inner surface of the spoke 20 and the outer peripheral surface of the rim 10. In this way, since the first weld bead structure 100 and the second weld bead structure 200 are formed at the connection between the spoke 20 and the rim 10, the welding area between the spoke 20 and the rim 10 is greatly increased, thereby ensuring the welding stability between the spoke 20 and the rim 10.

[0037] It should be noted that both the first weld bead structure 100 and the second weld bead structure 200 are annular, ensuring that the first weld bead structure 100 can completely weld and connect the outer wall surface of the boss 11 and the hole wall surface of the positioning hole 21 together, and at the same time ensuring that the second weld bead structure 200 can completely weld and connect the connection position between the axial inner surface of the spoke 20 and the outer peripheral surface of the rim 10 together, thereby ensuring the welding reliability between the spoke 20 and the rim 10.

[0038] As Figure 1 shown, a plurality of ventilation holes 22 are also provided on the spoke 20 at intervals along its circumferential direction, and the positioning hole 21 is located on the circumferential outer side of the plurality of ventilation holes 22. In this way, the arrangement of the plurality of ventilation holes 22 ensures that the heat generated by the braking mechanism during the braking process of the vehicle can be timely dissipated, thereby ensuring that the temperature of the tire will not increase and accelerate its aging, which is beneficial to extending the service life of the tire; in addition, the positioning hole 21 is located on the circumferential outer side of the plurality of ventilation holes 22, ensuring that the positioning hole 21 and the ventilation holes 22 do not interfere with each other.

[0039] To ensure the structural integrity of the wheel and the rationality of the rim 10 structure, as Figure 2 shown, an inflation hole 12 is provided on the inner wall surface of the rim 10, and an avoidance notch 23 for avoiding the inflation hole 12 is provided at the edge of a ventilation hole 22 on the spoke 20. Of course, when the ventilation hole 22 on the spoke 20 is opened large enough not to interfere with the valve, there is no need to provide an avoidance notch 23 on the spoke 20.

[0040] Embodiment Two

[0041] As Figure 7 shown, the difference between this embodiment and Embodiment One is that the boss 11 includes an axially limiting section 111 and a plugging section 112 connected in the direction away from the rim 10. Among them, a stop end face 113 is formed at the connection position between the axially limiting section 111 and the plugging section 112. After the plugging section 112 is inserted into the positioning hole 21, the stop end face 113 abuts against the axial inner surface of the spoke 20. In this way, by setting the boss 11 into a structural form including the axially limiting section 111 and the plugging section 112, and the thickness of the plugging section 112 is less than the thickness of the rim 10, it can not only avoid the size of the positioning hole 21 on the spoke 20 being too large and reducing the structural strength of the spoke 20, but also the stop end face 113 formed on the boss 11 plays an axially limiting role on the spoke 20, while ensuring that the spoke 20 can provide a stable and reliable supporting effect for the rim 10.

[0042] Embodiment Three

[0043] As Figure 8As shown, the difference between this embodiment and the first embodiment is that the positioning hole 21 is a blind hole. In this way, after the spoke 20 is inserted into the positioning hole 21 through the boss 11 and installed and positioned on the rim 10, the arrangement of the bottom surface of the blind hole plays a role in stopping and blocking the boss 11, not only preventing the boss 11 from protruding out of the positioning hole 21, but also ensuring that the boss 11 cannot be seen from the side where the spoke 20 is installed, thereby improving the overall aesthetic appearance of the wheel.

[0044] Embodiment Four

[0045] As Figure 9 and Figure 10 shown, the difference between this embodiment and the first embodiment is that the boss 11 is a columnar protrusion. In this way, since the cross-sectional area of the columnar protrusion is small, and the cross-section of the positioning hole 21 is adapted to the cross-section of the boss 11, it is possible to prevent the cross-sectional area of the positioning hole 21 from being too large and reducing the structural strength of the spoke 20, thereby ensuring that the spoke 20 can provide a stable and reliable supporting effect for the rim 10.

[0046] Preferably, the positioning hole 21 is a round hole and the boss 11 is cylindrical. In this way, it is beneficial to reduce the manufacturing difficulty of the positioning hole 21 and the boss 11, thereby ensuring the economy of the wheel.

[0047] Optionally, the positioning holes 21 and the bosses 11 are provided in a plurality of one-to-one correspondences, and the plurality of positioning holes 21 and the plurality of bosses 11 are arranged at intervals in the circumferential direction of the rim 10. In this way, with the simultaneous plugging and matching of the plurality of positioning holes 21 and the plurality of bosses 11, after the spoke 20 is installed and positioned on the rim 10, it is ensured that there is no relative rotation between the spoke 20 and the rim 10, thereby improving the installation accuracy of the spoke 20 and the connection stability with the rim 10.

[0048] Embodiment Five

[0049] In an embodiment not shown in the present application, the positioning hole 21 is an annular blind hole, and the boss 11 is an annular boss continuously arranged in the circumferential direction of the rim 10. In this way, while reducing the manufacturing difficulty of the positioning hole 21 and the boss 11, it is also convenient for the operator to directly align the boss 11 with the positioning hole 21 and insert it into the positioning hole 21, and then the spoke 20 can be installed and positioned on the rim 10, improving the efficiency of installing and positioning the spoke 20 on the rim 10.
