Description

Technology Field

[0001] The present invention relates to a wheel support for a vehicle having a hollow portion, and more specifically, to a wheel support for a vehicle that can achieve weight reduction and strength reinforcement by having a hollow portion. Background Technology

[0002] A vehicle's wheel supports are critical structural elements that support the vehicle's load and ensure stability during driving. Conventional wheel supports are generally designed as single structures or manufactured as solid, filled structures. However, this design approach has the disadvantage of potentially leading to reduced fuel efficiency and driving performance due to increased weight.

[0003] To address this, wheel supports with hollow sections are being manufactured; however, since a core shaped from sand is used to form the hollow section, there were limitations in that the shape was simple and the structure could only be made to facilitate easy removal. Prior art literature

[0004] Korean Registered Patent 10-2724984 (2024. 11. 01) The problem to be solved

[0005] The present invention is designed to resolve these problems and aims to provide a wheel support for a vehicle that can achieve weight reduction and strength reinforcement by having a hollow portion. means of solving the problem

[0006] To achieve the above objective, the present invention provides a wheel support for a vehicle having a hollow portion, comprising a first wheel support housing and a second wheel support housing connected to the first wheel support housing, wherein the interiors of the first wheel support housing and the second wheel support housing form a hollow portion.

[0007] The outer edge of the first wheel support housing is characterized by being implemented to be in close contact with and in contact with the outer edge of the second wheel support housing.

[0008] The outer rim of the first wheel support housing and the outer rim of the second wheel support housing are connected by welding or metal adhesive.

[0009] It is characterized by having reinforcing ribs provided inside the hollow section.

[0010] The connection area where the connection body to the vehicle is connected is provided in a solid form, and the hollow portion is formed across the area between the connection part and the rim of the mounting hole where the hub bearing is mounted, characterized by the wheel support body.

[0011] The shape of the outer edge surface of the first wheel support housing and the outer edge surface of the second wheel support housing are characterized by being formed with a toothed or uneven structure that is mutually coupled. Effects of the invention

[0012] According to the present invention, by forming hollow portions within the first wheel support housing and the second wheel support housing, weight reduction compared to conventional solid structures can be achieved, thereby providing the effect of improving vehicle fuel efficiency and driving performance. Furthermore, since the method of forming the hollow portions differs from the conventional core method, the degree of freedom in shape fabrication increases, and the efficiency of the production process can be improved.

[0013] By implementing the outer rims of the first wheel support housing and the second wheel support housing to be in close contact, precision during assembly can be increased, and a structurally stable integrated wheel support can be formed. This allows strength to be secured while maintaining the shape of the hollow section, thereby improving durability.

[0014] By connecting the outer edges of the first wheel support housing and the second wheel support housing with welding or metal adhesive, assembly strength can be further enhanced, and resistance to impact and load can be increased through the integrated structure after assembly. In addition, flexibility in the manufacturing process can be ensured by applying various joining methods.

[0015] By placing reinforcing ribs inside the hollow section, strength can be further enhanced while maintaining lightweight properties. This increases the structural stability of the wheel support and strengthens durability, reducing the risk of deformation or breakage during long-term use.

[0016] By designing the vehicle connection area of ​​the wheel support in a solid form, the bonding strength with the vehicle is increased, and structural stability can be secured even under high loads generated during driving. In addition, by limiting the formation of the hollow section to areas where connection with the vehicle is not required, lightweighting and strength can be achieved simultaneously.

[0017] By forming the outer edge surfaces of the first wheel support housing and the second wheel support housing into a toothed or uneven structure, the bonding strength can be further increased and assembly precision improved. This allows for minimizing deformation after assembly and strengthening resistance to vibration and shock. Brief explanation of the drawing

Specific details for implementing the invention

[0019] The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated and described in the drawings.

[0020] However, this is not intended to limit the invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0021] Terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but said components are not limited by said terms.

[0022] The above terms are used solely for the purpose of distinguishing one component from another.

[0023] For example, without departing from the scope of the present invention, the second component may be named the first component, and similarly, the first component may be named the second component.

[0024] The term "and / or" includes a combination of multiple related listed items or any of the multiple related listed items.

[0025] When it is stated that one component is "connected" or "joined" to another component, it should be understood that while it may be directly connected or joined to that other component, there may also be other components in between.

[0026] On the other hand, when it is stated that one component is "directly connected" or "directly coupled" to another component, it should be understood that there are no other components in between.

[0027] The terms used in this application are used merely to describe specific embodiments and are not intended to limit the invention.

[0028] A singular expression includes a plural expression unless the context clearly indicates otherwise.

[0029] In this application, terms such as "comprising" or "having" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0030] Hereinafter, embodiments will be described in detail with reference to the attached drawings, provided that identical or corresponding components are given the same reference number regardless of the drawing symbols, and redundant descriptions thereof will be omitted.

[0031] As illustrated in FIG. 1, the wheel support (1) (hereinafter referred to as the "wheel support") having a hollow portion according to the present invention has a mounting hole (2) formed in the center for mounting a hub bearing, a first connecting portion (11) connected to a strut is provided on the upper side, a second connecting portion (12) connected to a tie rod is provided on the side, and a third connecting portion (13) connected to a lower arm is provided on the lower side.

[0032] Although the drawing uses a knuckle as an example, it goes without saying that the present invention can also be applied to other configurations capable of supporting a wheel (e.g., a carrier).

[0033] As illustrated in FIGS. 2 and 3, the wheel support (1) includes a first wheel support housing (100) (or outer housing) and a second wheel support housing (200) (or inner housing) connected to the first wheel support housing (100).

[0034] The first wheel support housing (100) and the second wheel support housing (200) are each manufactured separately, and a first hollow portion (201) and a second hollow portion (201) are formed inside each. It is preferable that the first wheel support housing (100) and the second wheel support housing (200) be made of aluminum for weight reduction, but steel (e.g., cast iron) is also possible, and even if they are made of steel, sufficient weight reduction can be achieved because of the hollow portion.

[0035] A first wheel support housing (100) and a second wheel support housing (200) come into contact, and the first outer edge surface (103) and the second outer edge surface (203) are in close contact, thereby producing a single integrated wheel support (1), and a hollow portion (2) is formed inside the wheel support (1) by the first hollow portion (201) and the second hollow portion (201).

[0036] Here, as illustrated in FIGS. 4 to 6, it is preferable that the shape of the first outer edge surface (103) of the first wheel support housing (100) and the shape of the second outer edge surface (203) of the second wheel support housing (200) be in contact with each other so as to be in close contact.

[0037] For example, as illustrated in FIG. 4, if a curved surface (e.g., a concave surface) is formed on the first outer edge surface (103) of the first wheel support housing (100), it is preferable that a curved surface (e.g., a convex surface) corresponding to the curved surface is formed on the second outer edge surface (203) of the second wheel support housing (200).

[0038] Meanwhile, although not illustrated, the shape of the first outer edge surface (103) of the first wheel support housing (100) and the second outer edge surface (203) of the second wheel support housing (200) may be formed with a toothed or uneven structure that is mutually coupled.

[0039] The first outer edge surface (103) of the first wheel support housing (100) and the second outer edge surface (203) of the second wheel support housing (200) can be connected face-to-face by welding or metal adhesive.

[0040] Here, metal adhesives may include epoxy adhesives, cyanoacrylate adhesives, acrylic adhesives, silicone adhesives, modified silane adhesives, hybrid polymer adhesives, etc., but are not limited to these, and anything capable of bonding metals is possible.

[0041] Although hollow portions (101, 201) are adopted in many areas to reduce the weight of the wheel support (1), the connecting portions (11, 12, 13) in the configuration of the wheel support (1) where the connection with the vehicle is connected are inevitably provided in a solid form to maintain strength.

[0042] That is, the first connecting part (11) which is a strut connecting part provided on the upper part of the wheel support (1), the second connecting part (12) which is a tie rod connecting part connected to the side, and the third connecting part (13) which is a lower arm connecting part provided on the lower part are adopted in a solid form rather than a hollow form.

[0043] To this end, the first connecting part forming part (111) of the first wheel support housing (100), the second connecting part forming part (112) connected to the side, and the third connecting part forming part (113) provided at the bottom are also formed solidly, and the first connecting part forming part (211) of the second wheel support housing (200), the second connecting part forming part (212) connected to the side, and the third connecting part forming part (213) provided at the bottom are also formed solidly, and these solidly formed structures have a wider surface compared to the first outer edge surface (103) and the second outer edge surface (203) of the first wheel support housing (100) and the second wheel support housing (200), and are connected by facing each other with their wider surfaces.

[0044] And, the hollow portion (101, 201) is formed across the area between each connecting portion forming portion (111, 112, 113, 211, 212, 213) and the edge of the mounting hole (2) where the hub bearing is mounted.

[0045] That is, the first hollow portion (201) is formed between the periphery of the hub bearing first mounting hole (102) and the first connecting portion forming portion (111), the second connecting portion forming portion (112), and the third connecting portion forming portion (113), and the second hollow portion (201) is formed between the periphery of the hub bearing second mounting hole (202) and the first connecting portion forming portion (211), the second connecting portion forming portion (212), and the third connecting portion forming portion (213).

[0046] In addition, as illustrated in FIG. 7, the present invention may further include reinforcing ribs (120, 220) for internal strength reinforcement.

[0047] Accordingly, a first reinforcing rib (120) in an intersecting shape may be arranged inside the first hollow portion (201), and a second reinforcing rib (220) may be arranged inside the second hollow portion (201). The surface of the first reinforcing rib (120) and the surface of the second reinforcing rib (220) may be connected to each other by welding or metal adhesive, or they may remain separated without being connected by welding / adhesion, etc.

[0048] The reinforcing ribs are arranged in both directions and intersect, and as shown in Fig. 7, they may be composed of vertical ribs and horizontal ribs, or they may be arranged diagonally so that right downward ribs and left downward ribs intersect.

[0049] The first wheel support housing (100) and the second wheel support housing (200) of the present invention can each be manufactured by casting or die-casting using two sets of molds, and the first wheel support housing (100) having a first hollow portion (201) and the second wheel support housing (200) having a second hollow portion (201) are manufactured separately, and when the first wheel support housing (100) and the second wheel support housing (200) are joined, a hollow portion (2) is naturally formed inside the wheel support (1).

[0050] Therefore, since a core is not required to produce the hollow section as in conventional technology, the degree of freedom in shaping can be increased compared to a core-type hollow structure. Additionally, reinforcing ribs (120, 220) for strength reinforcement can be added to the hollow section (2) to secure additional strength overall or locally.

[0051] Although the present invention has been described above with reference to the embodiments illustrated in the drawings, this is merely for the purpose of explaining the invention, and those skilled in the art will understand that various modifications or equivalent embodiments are possible from the detailed description of the invention.

[0052] Therefore, the true scope of rights of the present invention must be determined by the technical concept of the patent claims. Explanation of the symbols
