Description

Technical Field

[0001] This application relates to the field of wheel hub technology, and more specifically to a wheel hub with low replacement cost after impact. Background Technology

[0002] A wheel hub is a metal automotive component that supports the tire and is mounted in the center on an axle.

[0003] Existing wheel hubs include spokes and rims. The spokes are connected to a rotating shaft, and the spokes are fixedly connected to the rim. A tire is fitted onto the rim. When a driver is driving a vehicle, or when the wheel hub collidees with a curb (i.e., a road curb), it is usually the outermost edge of the rim or spokes that collides with and breaks the curb. However, since the rim is machined as a single piece, and the spokes are welded to the rim, when the rim is damaged, the entire wheel hub needs to be replaced, which is costly.

[0004] Therefore, there is a need for a wheel hub with a replaceable outermost edge of the spokes and a low replacement cost after damage to the outer edge of the spokes. Summary of the Invention

[0005] The main objective of this application is to provide a wheel hub with low replacement cost after impact. The wheel hub includes a spoke, a rim, and a ring rim. The rim has a through hole. The spoke is located at one end of the through hole and is fixedly connected to the rim. The spoke divides the through hole into an outer chamber and an inner chamber. One end of the ring rim extends into the outer chamber and is detachably connected to the end of the rim. By separating the outer edge of the existing rim into a ring rim and making the ring rim detachably connected to the rim, the ring rim can be replaced after impact with a curb, without needing to replace the entire rim and spokes. Compared to the prior art, this has the advantages of replaceable outermost spokes and low replacement cost after damage to the outer edge of the spokes.

[0006] Another objective of this application is to provide a wheel hub with low replacement cost after impact, wherein the wheel spoke has an annular arched portion that arches upwards to a predetermined height toward the opening of the outer cavity. The wheel hub with low replacement cost after impact also includes a crash ring, which is detachably connected to the annular arched portion, and one side of the crash ring is in contact with the peak surface of the annular arched portion. By providing the crash ring, when the wheel body is deeply impacted by the curb, only the crash ring needs to be replaced.

[0007] To achieve at least one of the above-mentioned objectives, this application provides a low-cost wheel hub replacement method after impact, wherein the low-cost wheel hub replacement method after impact includes:

[0008] One spoke; and

[0009] A rim having a through hole, spokes located at one end of the through hole and fixedly connected to the rim, the spokes dividing the through hole into an outer chamber and an inner chamber; and

[0010] A rim, one end of which extends into the outer cavity and is detachably connected to the end of the wheel rim.

[0011] In one or more embodiments of this application, the spoke has an annular arch that arches upwards to a predetermined height toward the opening of the outer cavity.

[0012] In one or more embodiments of this application, the low-cost replacement wheel hub after a collision further includes a crash ring, which is detachably connected to the annular arch, and one side of the crash ring is in contact with the peak surface of the annular arch.

[0013] In one or more embodiments of this application, the rim includes an extension portion, a flat portion, and a curved portion. The flat portion is located between the extension portion and the curved portion. The extension portion and the flat portion are arranged at an angle. The curved portion and the extension portion face opposite directions. The outer ring of the flat portion is fixedly connected to the curved portion. The inner ring of the flat portion is fixedly connected to the extension portion. The extension portion extends into the through hole and is detachably connected to the rim. The flat portion abuts against the end of the rim.

[0014] In one or more embodiments of this application, the flat portion has an annular groove on the side near the extended portion, and a buffer ring is provided in the annular groove, the buffer ring abutting against the end of the rim.

[0015] In one or more embodiments of this application, the spokes have a central hole and a plurality of mounting holes, the mounting holes being arranged around the central axis of the central hole on the outside of the central hole.

[0016] In one or more embodiments of this application, the spokes have a plurality of heat dissipation holes arranged in a ring array, the heat dissipation holes being located outside the mounting holes.

[0017] In this embodiment, the low-cost replacement wheel hub after a collision includes a spoke, a rim, and a ring rim. The rim has a through hole, the spoke is located at one end of the through hole and is fixedly connected to the rim, and the spoke divides the through hole into an outer chamber and an inner chamber. One end of the ring rim extends into the outer chamber and is detachably connected to the end of the rim. By splitting the outer edge of the rim in the prior art into a ring rim and making the ring rim detachably connected to the rim, the ring rim can be replaced after a collision with the curb without replacing the entire rim and spokes. Compared with the prior art, this has the advantages of the outermost edge of the spoke being replaceable and the replacement cost being low after the outer edge of the spoke is damaged.

Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of this application is provided for illustrative purposes only and not for the purpose of limiting the application as defined in the appended claims and their equivalents.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] While ordinal numbers such as "first," "second," etc., will be used to describe various components, there is no limitation on which components are used herein. The term is used only to distinguish one component from another. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of the utility model concept. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0026] For example, replace the wheels with low-cost ones after a minor bump or scratch. (Refer to...) Figures 1 to 3 According to a preferred embodiment of the present invention, a wheel hub with low replacement cost after being bumped or knocked down includes a spoke 10, a rim 20 and a ring rim 30.

[0027] Specifically, such as Figure 1 As shown, the rim 20 has a through hole 201, and the spokes 10 are located at one end of the through hole 201 and are fixedly connected to the rim 20. The fixed connection method is preferably welding. The spokes 10 divide the through hole 201 into an outer cavity 2011 and an inner cavity 2012. It should be noted that the inner cavity 2012 provides space for placing components such as brake discs. In addition, one end of the rim 30 extends into the outer cavity 2011 and is detachably connected to the end of the rim 20.

[0028] Specifically, such as Figure 2 As shown, the rim 30 includes an extension portion 301, a flat portion 302, and a curved portion 303. The flat portion 302 is located between the extension portion 301 and the curved portion 303. The extension portion 301 and the flat portion 302 are arranged at an angle. The curved portion 303 and the extension portion 301 face opposite directions. The outer ring of the flat portion 302 is fixedly connected to the curved portion 303, and the inner ring of the flat portion 302 is fixedly connected to the extension portion 301. The fixed connection method includes, but is not limited to, integral processing. The extension portion 301 extends into the through hole 201 and is detachably connected to the rim 20 by screws. The flat portion 302 abuts against the end of the rim 20.

[0029] It should be noted that when a vehicle collides with a curb, the outermost rim 30 of the entire wheel hub usually contacts the curb first. At this time, after feeling obvious resistance, the driver moves the vehicle away from the curb, and the rim 30 is damaged after contact. During subsequent repairs, the repair personnel only need to remove the corresponding tire and replace the rim 30, without replacing the spokes 10 and the rim 20. By separating the outer edge of the rim 20 in the prior art into the replaceable rim 30, compared with the prior art, where the entire wheel hub needs to be replaced when the outer edge of the rim 20 is damaged, this embodiment only requires replacing the rim 30, which has the advantages of replaceable outermost spokes and lower replacement cost after damage to the outer edge of the spokes.

[0030] Furthermore, in the embodiments of this application, such as Figure 1 and Figure 3 As shown, the spoke 10 has an annular arched portion 101, which arches upwards to a predetermined height toward the opening of the outer cavity 2011.

[0031] Since the annular arched portion 101 is close to the rim 30, to avoid damage to the peak of the annular arched portion 101, such as... Figure 1 and Figure 3 As shown, the low-cost replacement wheel hub after a collision also includes a bumper ring 40. The outer edge of the bumper ring 40 is arched and conforms to the peak of the annular arch 101. The bumper ring 40 and the annular arch 101 are detachably connected by screws, and one side of the bumper ring 40 is in contact with the peak of the annular arch 101. If the collision between the wheel hub and the curb is significant, the curb will also contact the bumper ring 40 when damaging the rim 30, thus damaging the bumper ring 40. In this scenario, the repair personnel only need to replace the bumper ring 40 at the same time as replacing the rim 30, avoiding the situation where the spokes 10 need to be replaced even if the rim 30 is only slightly damaged.

[0032] Furthermore, to prevent the rim 30 from exerting excessive pressure on the outer edge of the wheel rim 20 and damaging the outer edge of the wheel rim 20 after being subjected to force, such as... Figure 2 As shown, the flat portion 302 has an annular groove 3021 on the side near the extension portion 301. A buffer ring 3022 is provided in the annular groove 3021. The buffer ring 3022 is preferably a rubber pad. The buffer ring 3022 abuts against the end of the rim 20.

[0033] It should be noted that by providing the buffer ring 3022, when the rim 30 is subjected to force and presses against the wheel rim 20, the buffer ring 3022 can provide a soft contact. In addition, under normal conditions, the wheel rim 20 abuts against the buffer ring 3022, preventing the buffer ring 3022 from falling off the annular groove 3021.

[0034] Furthermore, to achieve the connection between the wheel hub, which is a low-cost replacement after the impact, and the external wheel hub motor, such as... Figure 1 As shown, the spoke 10 has a central hole 102 and several mounting holes 103. The central axis of the central hole 102 coincides with the central axis of the spoke 10. The mounting holes 103 are arranged around the central axis of the central hole 102 on the outside of the central hole 102. It should be noted that bolts pass through the mounting holes 103 and are bolted to the external hub motor.

[0035] Furthermore, to facilitate heat exchange between the external brake disc and the outside air, such as Figure 1 As shown, the spokes 10 have a plurality of heat dissipation holes 104 arranged in a ring array. The heat dissipation holes 104 are located outside the mounting holes 103. In this embodiment, the heat dissipation holes 104 are located on the side of the annular arch 101 away from the central hole 102.

[0036] In summary, the wheel hub with low replacement cost after impact based on the embodiments of this application is explained, which provides advantages such as the outermost edge of the spokes being replaceable and the replacement cost being low after the outer edge of the spokes is damaged.

[0037] It is worth mentioning that, in this embodiment, the low-cost replacement wheel hub structure after impact is simple, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the low-cost replacement wheel hub provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0038] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
