Description

Technical Field

[0001] The present invention relates to the technical field of wheel hubs, and in particular to a wheel hub with steel wires passing through hollow spokes. Background Art

[0002] The wheel hub is the rotating part of the wheel core connected to the inner wheel steel of the tire through the pillars. It is the metal component that supports the center of the tire and is mounted on the axle. With the development of the automotive industry, research has shown that lightweighting the wheel hub can achieve better fuel economy.

[0003] Existing wheels are mostly made of pure alloy, which lacks toughness but offers a wide variety of styles, making them suitable for urban use. Current pure alloy wheels typically achieve lightweighting by modifying spoke shape and creating holes in the hub, reducing material usage while maintaining strength. This lightweighting is ideal for urban use but not for mountain or off-road use. Summary of the Invention

[0004] The object of the present invention is to provide a wheel hub with steel wires passing through hollow spokes, which has the characteristics of light weight and excellent deformation resistance.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] A wheel hub with steel wires passing through hollow spokes, comprising a rim, spokes, a wheel hub and steel wires;

[0007] The spoke includes a first supporting portion and a second supporting portion connected to each other, the tail end of the first supporting portion is connected to the wheel hub, the top end of the second supporting portion is connected to the wheel rim, the first supporting portion and the second supporting portion have an obtuse angle, the extension line of the second supporting portion deviates from the axis of the wheel hub, and the second supporting portion has a hollow portion;

[0008] One end of the steel wire is fixedly connected to the wheel axle hub, and the other end of the steel wire passes through the hollow portion and is fixedly connected to the rim.

[0009] Furthermore, the number of the spokes is multiple and evenly distributed between the rim and the axle hub;

[0010] Each of the spokes includes two second supporting parts, and each of the second supporting parts corresponds to one steel wire;

[0011] The two second supporting parts of one spoke are mirror-imaged, and the two steel wires corresponding to one spoke are mirror-imaged.

[0012] Furthermore, the symmetry line of the two steel wires corresponding to one spoke passes through the axis of the wheel hub, and the angle between the rim diameter line at the connection point of the steel wire and the rim and the symmetry line is 9.5°-10.5°.

[0013] Furthermore, the wheel axle hub is provided with a connection point, and two adjacent steel wires are connected to the same connection point, and the two adjacent steel wires correspond to two adjacent spokes.

[0014] Furthermore, the rim is provided with a mounting groove, the mounting groove has a first screw hole, the screw hole is covered with a pressing plate, the edge of the pressing plate is located in the mounting groove and the size of the pressing plate matches the mounting groove, so that the screw passes through the pressing plate and is screwed into the first screw hole to press the end of the steel wire between the pressing plate and the rim.

[0015] Furthermore, a connecting protrusion is provided on a side of the wheel axle hub close to the rim, a connecting groove is provided on a side of the connecting protrusion facing the rim, and the end of the steel wire extends into the connecting groove;

[0016] A second screw hole is provided on one side wall of the connecting groove, and a through hole is provided on the other side wall of the connecting groove; a screw is passed through the through hole and screwed into the second screw hole to press the end of the steel wire tightly into the connecting groove.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] The following combination Figures 1 to 4, describing a hub with steel wire passing through hollow spokes according to an embodiment of the present invention.

[0031] like Figure 1 and Figure 2 As shown, the steel wire runs through the hub with hollow spokes, which includes a rim 1, spokes 2, a hub 3 and a steel wire 4;

[0032] The spoke 2 includes a first support portion 21 and a second support portion 22 connected to each other. The tail end of the first support portion 21 is connected to the axle hub 3, and the top end of the second support portion 22 is connected to the rim 1. The first support portion 21 and the second support portion 22 form an obtuse angle. The extension line of the second support portion 22 deviates from the axis of the axle hub 3. The second support portion 22 has a hollow portion 23.

[0033] One end of the steel wire 4 is fixedly connected to the wheel hub 3 , and the other end of the steel wire 4 passes through the hollow portion 23 and is fixedly connected to the rim 1 .

[0034] Existing pure alloy wheels lack toughness but offer a variety of styles, making them suitable for urban use. Existing pure steel wire spokes have a single style but exceptional toughness and deformation resistance, making them suitable for mountain and off-road use. The present invention combines these two existing wheel hubs to create a lightweight hub suitable for both urban and mountain and off-road use. Specifically, the spokes in the hub of the present invention are provided with hollow sections, through which steel wire passes. This reduces the weight of the hub while reinforcing the hollow sections, enhancing the hub's structure while maintaining an aesthetically pleasing appearance.

[0035] To ensure smooth penetration of the steel wire through the hollowed portion and achieve optimal reinforcement, the first and second support portions are positioned at an obtuse angle, with the extension of the second support portion offset from the hub axis. This also ensures the overall aesthetics of the hub. Specifically, the steel wire is made of carbon steel or stainless steel. The required performance of the steel wire is: tensile strength of 908-1270 MPa and elongation at break ≥ 6%.

[0036] The blank of the wheel hub of the embodiment of the present invention is formed by integral casting, and after forming, it is further reshaped and steel wire is installed to obtain the wheel hub of the embodiment of the present invention.

[0037] In order to achieve better aesthetic effects and better anti-deformation ability, further, the number of spokes 2 is multiple, and they are evenly distributed between the rim 1 and the axle hub 3; each spoke 2 includes two second support parts 22, and each second support part 22 corresponds to a steel wire 4; the two second support parts 22 of a spoke 2 are mirror-symmetrical, and the two steel wires 4 corresponding to a spoke 2 are mirror-symmetrical.

[0038] It should be noted that the spoke 2 in this embodiment has only one first support portion 21, which is Y-shaped. In other embodiments, the spoke 2 has multiple first support portions 21, each connected to a second support portion 22. The shape and structure of the spoke 2 can vary, but the second support portion 22 of the spoke 2 is required to have a hollow portion 23, through which the steel wire 4 is passed for reinforcement.

[0039] Preferably, the number of spokes 2 is five. Optionally, the number of spokes 4 is four.

[0040] Furthermore, the line of symmetry between the two steel wires 4 corresponding to a spoke 2 passes through the axis of the hub 3. This maintains a beautiful appearance while maintaining consistent load-bearing capacity for each steel wire 4, ensuring uniform strength across the entire hub. To ensure the steel wire 4 has better load-bearing capacity, the angle between the rim 1 diameter line at the connection point between the steel wire 4 and the rim 1 and the line of symmetry is 9.5°-10.5°. Preferably, when there are five spokes 2, this angle is 9.8°. Specifically, the connection point between the steel wire 4 and the rim 1 refers to the location of the screws used to secure the steel wire 4.

[0041] To simplify the manufacturing process, the hub 3 is provided with a connection point. Two adjacent steel wires 4 are connected at the same connection point. These two adjacent steel wires 4 correspond to two adjacent spokes 2. That is, when there are five spokes 1, there are ten steel wires 4, and the hub 3 has five connection points. The angle between the two adjacent connection points and the axis of the hub is 72°. This simplifies the manufacturing process while also simplifying the hub structure and improving its appearance.

[0042] like Figure 3 As shown, in order to better position the steel wire 4 on the axle hub 3, a connecting protrusion 31 is further provided on the side of the axle hub 3 close to the rim 1. The connecting protrusion 31 is provided with a connecting groove 32 on the side facing the rim 1, and the end of the steel wire 4 extends into the connecting groove 32; a second screw hole (not shown in the figure) is provided on one side of the groove wall of the connecting groove 32, and a through hole (not shown in the figure) is provided on the other side of the groove wall; a screw is passed through the through hole and screwed into the second screw hole to press the end of the steel wire 4 into the connecting groove 32. The connecting protrusion 31 is integrally formed with the wheel hub, and the connecting groove 32 is processed after forming. The groove wall of the connecting groove 32 on the side with the second screw hole is thicker, and the groove wall on the other side is thinner. When the screw is tightened in the connecting groove 32, the thinner groove wall is slightly deformed to ensure that the end of the steel wire 4 is pressed tightly.

[0043] Preferably, the end of the steel wire 4 close to one end of the axle hub 3 is bent to form an elbow, and the elbow crosses the screw to achieve the installation of the steel wire on the axle hub 3.

[0044] like Figure 4As shown, in order to better position the steel wire 4 on the rim 1, the rim 1 is further provided with a mounting groove, a first screw hole is provided in the mounting groove, and a pressing piece 11 is covered on the screw hole. The edge of the pressing piece is located in the mounting groove and the size of the pressing piece matches the mounting groove. The screw passes through the pressing piece 11 and is screwed into the first screw hole to press the end of the steel wire 4 between the pressing piece 11 and the rim 1. The pressing piece and the screw are used to achieve the positioning of the end of the steel wire 4 close to the rim.

[0045] In order to improve the strength of the wheel hub, the spoke 2 further includes two reinforcing strips 24, which are mirror-symmetrically arranged on both sides of the first support part 21. One end of the reinforcing strip 24 is connected to the wheel hub 3, and the other end is connected to the second support part 22; the connection point between the reinforcing strip 24 and the second support part 22 is close to the connection between the first support part 21 and the second support part 22.

[0046] To enhance the strength of the rim 1, evenly spaced reinforcing ribs 12 are further provided on the front of the rim 1. A mounting groove 13 is located between two adjacent reinforcing ribs 12, and the width of the mounting groove 13 is the same as the spacing between the two adjacent reinforcing ribs 12. This simplifies the processing of the mounting groove 13 and further ensures the aesthetics of the wheel hub.
