Description

Technical Field

[0001] This application belongs to the field of automotive chassis components, and in particular relates to a precision forging of a three-post structure off-road vehicle vibration damping seat. Background Technology

[0002] When off-road vehicles operate in harsh road conditions, their suspension systems, especially the shock absorber connection points, need to withstand complex and severe multi-directional impact loads. Traditional shock absorber mounts are mostly manufactured using casting or welding methods, resulting in discontinuous material flow lines and internal defects such as porosity and slag inclusions, leading to low overall structural strength and poor fatigue resistance. Particularly in the mount portion connecting the shock absorber, under long-term alternating stress from different directions, cracks or even fractures are easily generated at stress concentration points, seriously affecting the vehicle's safety and reliability. Therefore, it is necessary to solve the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this application is to provide a precision forging of a three-column structure off-road vehicle vibration damping seat to solve the technical problem of low structural strength of vibration damping seats in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a precision forging of a three-post structure off-road vehicle vibration damping seat, comprising:

[0005] The main body is formed into a columnar structure with a dumbbell-shaped cross-section;

[0006] The connecting structure includes a first connecting post, a second connecting post, and a third connecting post integrally forged on the body portion, wherein the height direction of the body portion is perpendicular to the height direction of the first connecting post, the height direction of the second connecting post, and the height direction of the third connecting post, respectively.

[0007] Optionally, the height directions of the second connecting post and the third connecting post are parallel and both perpendicular to the height direction of the first connecting post;

[0008] The geometric centers of the first connecting post, the second connecting post, and the third connecting post are all coplanar.

[0009] Optionally, the geometric center of the body portion coincides with the central axis of the first connecting column.

[0010] Optionally, the first connecting post, the second connecting post, and the third connecting post respectively form an arched connecting surface with the main body.

[0011] Optionally, the connecting surface is also formed between the first connecting post and the second connecting post.

[0012] Optionally, raised reinforcing ribs are formed on the connecting surface.

[0013] Optionally, the second connecting post and / or the third connecting post may also have pre-drilled holes for connecting to the target structure.

[0014] The third connecting post is also pre-set with a connecting boss for machining the target connecting structure, and the connecting boss is coaxially arranged with the third connecting post.

[0015] The beneficial effects of the precision forged three-column structure off-road vehicle vibration damper seat provided in this application are as follows: Compared with the prior art, in the precision forged three-column structure off-road vehicle vibration damper seat provided in this application, since the main load-bearing body is set as a dumbbell-shaped columnar structure, it has a significantly higher section modulus and moment of inertia with similar material usage compared to traditional rectangular or circular sections, thus more effectively resisting bending and torsional deformation; at the same time, the dumbbell-shaped streamlined shape helps to avoid stress concentration caused by sharp corners, greatly improving fatigue life. In addition, the three connecting columns with their height directions perpendicular to the height direction of the body can directly transmit impact loads from different directions to the body through the shortest path and be efficiently absorbed and dispersed, which fundamentally improves the structural strength and rigidity of the precision forged three-column structure off-road vehicle vibration damper seat in this embodiment, far superior to the prior art.

[0026] Please refer to the following: Figures 1 to 4 This application now describes a precision forging of a three-post structure off-road vehicle vibration damper seat according to an embodiment. The precision forging of the three-post structure off-road vehicle vibration damper seat includes a body portion 100 and a connecting structure. Wherein:

[0027] The body portion 100 forms a columnar structure with a dumbbell-shaped cross-section. The connecting structure includes a first connecting column 101, a second connecting column 102, and a third connecting column 103 integrally forged onto the body portion 100. The height direction of the body portion 100 is perpendicular to the height direction of the first connecting column 101, the second connecting column 102, and the third connecting column 103, respectively. In this embodiment, the body portion 100, the first connecting column 101, the second connecting column 102, and the third connecting column 103 can be made of steel materials commonly used in the art. Furthermore, the cross-sectional shape of the first connecting column 101, the second connecting column 102, and the third connecting column 103 is not limited and can be flexibly set to commonly used circular, square, or rectangular shapes according to specific functional needs; this will not be elaborated upon further here. For ease of explanation, this embodiment uses a circular cross-sectional shape for the first connecting column 101, the second connecting column 102, and the third connecting column 103 as an example.

[0028] According to the structure provided in this embodiment, in the precision forging of the three-column structure off-road vehicle vibration damping seat provided in this embodiment, since the main body 100 bearing the main load is set as a dumbbell-shaped columnar structure, it has a significantly higher section modulus and moment of inertia with similar material usage compared to traditional rectangular or circular sections, thus more effectively resisting bending and torsional deformation. At the same time, the streamlined dumbbell shape helps to avoid stress concentration caused by sharp corners, greatly improving fatigue life. In addition, the three connecting columns perpendicular to the height direction of the main body 100 can directly transmit impact loads from different directions to the main body 100 through the shortest path and be efficiently absorbed and dispersed. This fundamentally improves the structural strength and rigidity of the precision forging of the three-column structure off-road vehicle vibration damping seat in this embodiment, far superior to the prior art.

[0029] In this embodiment, the two ends of the main body 100 are flat, which can provide a good initial positioning reference for machining the first connecting post 101, the second connecting post 102 and the third connecting post 103, thereby improving machining efficiency.

[0030] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4The second connecting column 102 and the third connecting column 103 are parallel in height direction and perpendicular to the height direction of the first connecting column 101; the geometric centers of the first connecting column 101, the second connecting column 102, the third connecting column 103, and the body part 100 are all coplanar. According to the structure provided in this embodiment, the coplanar design of the geometric centers of the three connecting columns and the body part 100 further optimizes the mechanical properties of the three-column structure off-road vehicle vibration damping seat forging, ensuring that impact loads from different directions can be more evenly transmitted to the dumbbell-shaped body part 100, avoiding additional torque or stress concentration caused by structural asymmetry, and optimizing the load distribution and transmission path. This further improves the structural strength of the three-column structure off-road vehicle vibration damping seat forging in this embodiment.

[0031] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The geometric center of the body portion 100 coincides with the central axis of the first connecting column 101. According to the structure provided in this embodiment, when an impact load is transmitted to the body portion 100 through the first connecting column 101, its force will be directly diffused along the core axis of the dumbbell-shaped body portion 100. This allows the material on the body portion 100 to be used most fully to resist deformation, thereby further improving the structural strength of the three-column structure off-road vehicle vibration damping seat forging in this embodiment.

[0032] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The first connecting column 101, the second connecting column 102, and the third connecting column 103 each form an arched connecting surface 104 with the main body 100. According to the structure provided in this embodiment, the design of the arched connecting surface 104 can fundamentally eliminate the sharp corners at the junctions of each connecting column and the main body 100, thereby greatly dispersing and reducing the stress peaks at each junction. This can further improve the structural strength of the precision forged three-column structure off-road vehicle vibration damping seat in this embodiment.

[0033] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The connecting surface 104 is also formed between the first connecting column 101 and the second connecting column 102. According to the structure provided in this embodiment, the addition of the arched connecting surface 104 between the first connecting column 101 and the second connecting column 102 can expand the coverage of stress relief, thereby effectively solving the complex stress concentration problem that may occur at the joint of the first connecting column 101 and the second connecting column 102 due to different force directions. This can also further improve the structural strength of the precision forged three-column structure off-road vehicle vibration damping seat in this embodiment.

[0034] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4A raised reinforcing rib 105 is formed on the connecting surface 104. According to the structure provided in this embodiment, adding a raised reinforcing rib 105 to the original arched connecting surface 104 can effectively suppress the slight elastic deformation that may occur on the connecting surface 104 when subjected to extremely high loads, significantly enhance the local stiffness and bending resistance of the connection root, and thus further improve the structural strength of the three-column structure off-road vehicle vibration damping seat forging in this embodiment.

[0035] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The second connecting post 102 and / or the third connecting post 103 are also pre-drilled with pre-drilled holes 106 for connecting the target structure. In this embodiment, the shape of the pre-drilled holes 106 is a circular hole commonly used in the art. In addition, in the specific implementation process, the depth of the pre-drilled holes 106 needs to be determined according to the position or size of the target structure, which will not be elaborated here. According to the structure provided in this embodiment, the pre-drilled holes 106 on the second connecting post 102 and the third connecting post 103 not only facilitate subsequent machining and reduce machining allowance, but more importantly, the pre-drilled holes 106 formed directly from the high-strength forging body have continuous metal flow lines and higher strength, which can further improve the structural strength of the precision forging of the three-post structure off-road vehicle vibration damping seat in this embodiment.

[0036] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The third connecting column 103 is also pre-fabricated with a connecting boss 107 for machining the target connecting structure. The connecting boss 107 is coaxially arranged with the third connecting column 103. According to the structure provided in this embodiment, the pre-fabricated coaxial connecting boss 107 at the end of the third connecting column 103 can provide sufficient process allowance and accurate positioning reference for subsequent machining of the target connecting structure (such as drilling, milling, tapping to connect the vibration damper). This can avoid the waste of material and positioning difficulties in machining from a complete plane, and can also ensure the accuracy and strength of the final threaded hole or connecting surface 104, thereby further improving the structural strength of the precision forging of the three-column structure off-road vehicle vibration damper seat in this embodiment.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
