Highly pressure-resistant automobile steel wheel hub

Abstract

This utility model discloses a high-compression-resistant steel automotive wheel hub, comprising a rim, spokes, and a center disc from the outside in. The rim has a ring structure with symmetrical inner and outer sides. The edge of the rim has a multi-step structure. One end of the spoke is welded to the side wall of the center disc, and the other end of the spoke is engaged with and welded to the multi-step structure. The spokes have a streamlined structure with supporting columns protruding to both sides in the middle. In this application, by casting the steel spokes into a streamlined structure, a certain yield strength is increased, giving it a certain degree of toughness. Under stress, the supporting columns in the middle provide the main support, while the outer parts disperse stress, resulting in more balanced compressive strength. Even when subjected to lateral stress, energy absorption and release can prevent breakage.

Description

Technical Field

[0001] This utility model relates to automobile wheel hubs, and more particularly to high-compression-resistant automobile steel wheel hubs. Background Technology

[0002] Car wheels are an indispensable component of a vehicle. They not only support the tires and transmit power, but also perform multiple functions such as shock absorption, vehicle protection, and influencing vehicle performance and safety. Choosing high-quality wheels is crucial for vehicle performance and driving experience.

[0003] Patent application number CN201110340917.2 discloses an automobile wheel hub, including a rim (1) and an axle hub (2), and also includes multiple rod-shaped spokes (3), which connect the rim (1) and the axle hub (2). This automobile wheel hub has the advantages of good safety performance, uniform stress distribution, light weight, and good heat dissipation performance.

[0004] Currently, most wheel hubs on the market have the same structure as described above, using spokes with straight support for support. However, this support structure only considers local support and is not easy to yield when subjected to lateral force, making it prone to breakage. When the load increases dramatically, the stress is also relatively concentrated. In addition, its functionality is also poor. Utility Model Content

[0005] In view of the shortcomings of the existing technology in setting a straight support structure, which is prone to breakage under special conditions, this utility model provides a high-compression-resistant automotive steel wheel hub.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A high-compression-resistant automotive steel wheel hub includes a rim, spokes, and a center disc from the outside to the inside. The rim has a ring structure with symmetrical inner and outer sides. The edge of the rim has a multi-step structure. One end of the spoke is welded to the side wall of the center disc, and the other end of the spoke is fastened to the multi-step structure and welded for fixation. The spoke has a streamlined structure and has support columns protruding to both sides in the middle.

[0008] Preferably, the wheel hub includes a first side portion, a ring body, and a second side portion, with the first side portion and the second side portion located at the inner and outer ends of the ring body, respectively.

[0009] Preferably, the multi-step structure is provided on the first and second sides.

[0010] Preferably, the other end of the spoke is fastened to the multi-step structure on the first side and extends toward the center of the ring.

[0011] Preferably, the cross-section of the ring has a V-shaped structure and the included angle of the V-shape is between 173 and 177.

[0012] Preferably, the center plate has several arrayed bolt holes for mounting the brake disc inside the wheel hub.

[0013] Preferably, the center plate has a central hole for mounting the bearing.

[0014] Preferably, there are multiple spokes arranged in an evenly distributed array.

[0015] Compared with the prior art, the advantages of this utility model are as follows: By casting the steel spokes into a streamlined structure, a certain yield strength is increased, giving it a certain toughness. When under stress, the central support column provides the main support, while the outer part disperses the stress, making the compressive strength more balanced. Even when the side is under stress, it can achieve the purpose of preventing breakage by absorbing and releasing energy. Attached Figure Description

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

[0023] This embodiment mainly describes the title of high-compression-resistant automotive steel wheel hub, as follows:

[0024] See attached document Figure 1-3 A high-compression-resistant automotive steel wheel hub includes a rim 10 from the outside to the inside, multiple evenly distributed spokes 20, and a center disc 30. The rim 10 has a ring structure with symmetrical inner and outer sides. The edge of the rim 10 has a multi-step structure. One end of the spokes 20 is welded to the side wall of the center disc 30, and the other end of the spokes 20 is fastened to the multi-step structure and welded for fixation. The spokes 20 have a streamlined structure 201 and a support column 202 protruding to both sides in the middle. The length of the support column 202 is adapted to the length of the streamlined structure 201. In this design, the steel spokes 20 are cast into a streamlined structure 201 to increase their yield strength and toughness. Under stress, the central support column 202 provides the main support, while the outer part disperses the stress, making the compressive strength more balanced. Even when subjected to lateral stress, the energy can be released to prevent breakage. In addition, this design sets a stepped structure on the side of the rim 10 and welds the spokes 20 to the stepped structure. The weld line is greatly increased, which increases the stability of the connection position.

[0025] Preferably, the hub includes a first side portion 101, a ring body 102, and a second side portion 103, with the first side portion 101 and the second side portion 103 located at the inner and outer ends of the ring body 102, respectively. Preferably, a multi-step structure is provided at the first side portion 101 and the second side portion 103. Preferably, the other end of the spoke 20 is engaged with the multi-step structure at the first side portion 101 and extends towards the center of the ring body 102.

[0026] Preferably, the cross-section of the ring 102 is V-shaped with an included angle between 173° and 177°. Compared to a straight extension, the V-shaped structure can adapt to changes in load through slight deformation.

[0027] Preferably, the center disc 30 has a plurality of arrayed bolt holes for mounting a brake disc inside the wheel hub. Preferably, the center disc 30 has a center hole for mounting a bearing.
