Description

TECHNICAL FIELD

[0001] The utility model belongs to the rim reinforcing technical field, concretely, the utility model relates to a steel wheel rim reinforcing piece. BACKGROUND

[0002] The steel wheel is generally welded into a whole by a rim and a spoke, and a tire is installed on the rim. The rim is produced by an equal-thickness special steel plate, and the weakest strength is at the rim due to the structural limitation. During long-time driving, the tire of the vehicle is subjected to alternating stress of radial force and lateral force, especially the large impact load of the tire, which is first transmitted to the bead seat and the rim. The rim, as the weakest strength part of the rim, will be deformed in the radial direction and the axial direction, which will cause the tire to rapidly leak and the vehicle to lose control, resulting in a traffic accident. In addition, in order to reduce the wind resistance and have a good appearance, a wheel cover is installed on the outer side of the steel wheel and is fixed by embedding the claws of the wheel cover into the limiting groove of the wheel, but the depth of the limiting groove is only 1.5 mm due to the structural limitation, so there is a risk of the wheel cover being detached during driving.

[0003] Chinese patent (publication number: 108621693A) discloses a detachable rimless tire wheel rim and a rimless tire wheel. The detachable rimless tire wheel rim includes a rim body and annular rims located on both sides of the rim body. The height and shape of the annular rims are adapted to the height and shape of the bead part of the corresponding inner tire of the rim. The annular rims include fixed rims and detachable rims. The detachable rims are connected to the rim body and are provided with tire dismounting deep grooves for dismounting the tire. The outer surface of the rim body between the fixed rims and the tire dismounting deep grooves forms a first bead seat in a radial taper shape. The outer surface of the rim body between the detachable rims and the tire dismounting deep grooves forms a second bead seat in a radial taper shape. However, the rim of the wheel is easy to be damaged by heat, and the strength is not high enough. UTILITY MODEL CONTENTS

[0016] The specific embodiments of the present application will be further described in details below with reference to the accompanying drawings, the purpose of which is to help the skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solutions of the present application, and to facilitate its implementation.

[0017] As Figures 1-2 shown, a steel wheel rim reinforcement includes a rim 1, spokes 3, the rim 1 contains a bead seat 12 and a rim 11, the rim 1 is provided with a reinforcement 2, the reinforcement 2 is embedded in the rim 1. The rim 1 provides stable support for the tire, during vehicle driving, the tire bears various forces from the road, including vertical force, lateral force and driving force, etc., the rim 1 evenly disperses these forces through its solid structure, avoiding large deformation of the rim 1 due to excessive local stress, which may cause tire leakage. The spokes 3 provide important support for the rim 1, ensuring that the rim 1 maintains the correct position and shape during vehicle driving. The bead seat 12 is used to fix the tire, ensuring that the tire can be firmly attached to the rim 1 after installation. The bead seat 12 can also act as a buffer to some extent, reducing the impact and wear between the tire and the rim 1. The rim 11 is used to protect the tire from scratches and collisions with external objects during driving. The reinforcement 2 can enhance the strength and stiffness of the rim. During vehicle driving, the rim 1 will be subjected to various complex forces, such as radial force, axial force and torque, etc., the reinforcement 2 can effectively share these forces, improve the carrying capacity of the rim 1, and prevent the rim 1 from deforming or damaging.

[0018] The rim 1 is provided with a limiting groove 13, the cross section of the reinforcement 2 follows the shape of the inner surface of the rim 11, and the reinforcement 2 extends from the rim 11 to the limiting groove 13. The cross section of the reinforcement 2 follows the shape of the inner surface of the rim 11, and the reinforcement 2 extends from the rim 11 to the limiting groove 13, so that the reinforcement 2 can closely fit with the rim 1 and jointly bear external forces. When the wheel bears a large radial load, the reinforcement 2 can disperse the force to various parts of the rim 1 through its own structure, reducing the stress concentration of the rim 1.

[0019] The rim 1 is provided with a rim inner groove 14, and the reinforcing member 2 is provided with an outer end protrusion 21 and an inner end protrusion 22, the outer end protrusion 21 is embedded into the rim inner groove 14 of the rim 1, and the inner end protrusion 22 is embedded into the limiting groove 13 of the rim 1. Through the close cooperation of the outer end protrusion 21 and the rim inner groove 14 and the close cooperation of the inner end protrusion 22 and the limiting groove 13, the strength and stability of the rim 11 are further improved. The radial and axial strength of the rim 11 is enhanced, and the deformation or falling off of the rim 11 under external force is prevented. When the vehicle is running at high speed or passing through complex road conditions, the rim 11 can better protect the tire and improve the safety of the wheel. After the reinforcing member 2 is embedded into the rim 1, the radial and axial strength of the rim 11 of the rim 1 is improved, and the thickness of the rim 11 is only increased by 0.5-0.8mm, which does not affect the installation of the wheel cover; after the reinforcing member 2 is embedded into the rim 1, the depth of the limiting groove 13 of the rim 1 is increased by 0.5-0.8mm, which can effectively prevent the wheel cover pawl from falling out.

[0020] The reinforcing member 2 is pressed into the rim 11. After the reinforcing member 2 is pressed into the rim 11, the two are tightly combined to form a more stable overall structure. Compared with welding, the press-in installation method has obvious process advantages. Welding is easy to produce thermal stress in the welding area, which changes the material properties and even causes deformation, affecting the overall quality and performance of the wheel. By pressing the reinforcing member 2 into the rim 11, the installation process is simple and direct, without the need for complex welding process, reducing the process and time cost in the manufacturing process. At the same time, the press-in type does not cause thermal effects on the original performance of the material, ensuring the original strength and toughness of the reinforcing member 2 and the rim 11, and improving the quality stability and reliability of the wheel from the manufacturing process point of view.

[0021] The outer end protrusion 21 is embedded into the rim inner groove 14 of the rim 1, and the interference amount is 1.0-2.0mm. The interference amount is within the range of 1.0-2.0mm, so that the reinforcing member 2 will not easily displace or loosen in the rim 1 after installation.

[0022] The inner end protrusion 22 structure of the reinforcing member is embedded into the limiting groove 13, and the interference amount is 0.5-1mm. The interference amount is 0.5-1mm. So that the reinforcing member 2 will not easily displace or loosen in the rim 1 after installation.

[0023] The thickness of the reinforcing member 2 is 0.5-0.8mm. The thickness of the reinforcing member is 0.5-0.8mm, combined with the interference amount design, which further enhances the comprehensive performance of the rim 11. Under the premise of meeting the strength and rigidity of the reinforcing member 2, reasonable thickness design can avoid increasing the overall weight of the wheel due to the over-thickness of the reinforcing member 2.

[0024] Effects of the embodiment

[0025] The strength and stability of the flange 11 are further improved by the close fit of the outer end protrusion 21 with the inner groove 14 of the flange and the close fit of the inner end protrusion 22 with the limiting groove 13. The radial and axial strength of the flange 11 is enhanced, and the flange 11 can be prevented from deforming or falling off when subjected to external force. When the vehicle is running at high speed or passing through complex road conditions, the flange 11 can better protect the tire and improve the safety of the wheel. After the reinforcing part 2 is embedded into the rim 1, the radial and axial strength of the flange 11 of the rim 1 is improved, and the thickness of the flange 11 is only increased by 0.5-0.8 mm, without affecting the installation of the wheel cover; after the reinforcing part 2 is embedded into the rim 1, the depth of the limiting groove 13 of the rim 1 is increased by 0.5-0.8 mm, which can effectively prevent the wheel cover pawl from falling out. The thickness of the reinforcing part is 0.5-0.8 mm, and the interference amount is designed, which further enhances the comprehensive performance of the flange 11. Under the premise of meeting the strength and rigidity of the reinforcing flange 11, the overall weight of the wheel can be avoided due to the over-thickness of the reinforcing part 2.

[0026] The utility model is described above in conjunction with the drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned manner. As long as various non-essential improvements are made by adopting the method concept and technical scheme of the utility model; or the above-mentioned concept and technical scheme of the utility model are directly applied to other occasions without improvement, all of which are within the protection scope of the utility model.
