Description

Technical Field

[0001] This application belongs to the field of vehicle body suspension system connection structure, and in particular relates to a novel double-wishbone intermediate cantilever structure. Background Technology

[0002] An intermediate cantilever is a suspension component used in various engineering machinery, vehicles, and heavy equipment to directly connect to damping springs and the main beam. Existing intermediate cantilever structures are mostly constructed by stamping sheet metal and then welding it. Under complex loads, these structures are prone to stress concentration, structural deformation, and fatigue damage. Especially under high loads or long-term vibration conditions, welding defects can lead to insufficient strength and torsional resistance, directly affecting the overall stability and service life of the equipment. Therefore, it is necessary to solve these technical problems. Summary of the Invention

[0003] The purpose of this application is to provide a novel double-forked intermediate cantilever structure to solve the technical problem of insufficient strength of cantilever structures in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a novel double-forked intermediate cantilever structure, comprising:

[0005] The first body part;

[0006] The second body portion is connected to the end of the first body portion along the length direction of the first body portion. The first body portion forms a first connecting groove at the end away from the second body portion, and the second body portion forms a second connecting groove. The first body portion also forms an open collapsible cavity between the first connecting groove and the second connecting groove. The collapsible cavity is disposed on opposite sides of the first body portion and the openings are opposite to each other. The first body portion forms an "I"-shaped cross-sectional shape through the collapsible cavity in its length direction and width direction, respectively.

[0007] Optionally, the first connecting groove and the second connecting groove extend in the same direction and the first body portion and the second body portion cooperate in the depth direction of the collapsed cavity to form an I-shaped structure.

[0008] Optionally, both the first body portion and the second body portion are symmetrical geometric shapes, and the center planes of symmetry of the first body portion and the second body portion coincide.

[0009] Optionally, the common center plane of symmetry of the first body portion and the second body portion is perpendicular to the depth direction of the collapsed cavity and is located between adjacent collapsed cavities.

[0010] Optionally, a plurality of mounting holes are formed on the first body portion, and the mounting holes are spaced apart along the edge of the first body portion; and a shaft hole is formed on the second body portion.

[0011] Optionally, the mounting holes on the first body are arranged in a triangular pattern; the axis of the shaft hole on the second body is coplanar with the axis of the mounting hole in the center of the first body and the symmetrical center plane of the collapsed cavities on both sides.

[0012] Optionally, a limiting hole coaxially communicating with the mounting hole is also formed on the first body portion, and the limiting hole has at least two different radial dimensions.

[0013] The beneficial effects of the novel double-forked intermediate cantilever structure provided in this application are as follows: Compared with the prior art, in the novel double-forked intermediate cantilever structure provided in this application, by setting open and mutually opposing collapsed cavities on both sides of the first body part, the first body part can form an I-shaped cross-sectional structure in both length and width directions. Since the double I-shaped structure can effectively disperse stress concentration and enhance load support stability, it can significantly improve the overall stiffness and bending and torsional resistance of the novel double-forked intermediate cantilever structure in this application, and can also maintain a lighter overall weight, which is far superior to the prior art.

[0026] Please refer to the following: Figures 1 to 6 The present application will now describe a novel double-forked intermediate cantilever structure according to an embodiment. This novel double-forked intermediate cantilever structure includes a first body portion 101 and a second body portion 102. Wherein:

[0027] The second body portion 102 is connected to the end of the first body portion 101 along the length direction of the first body portion 101. The first body portion 101 forms a first connecting groove 103 at the end away from the second body portion 102, and the second body portion 102 forms a second connecting groove 104. The first body portion 101 also forms an open collapsible cavity 105 between the first connecting groove 103 and the second connecting groove 104. The collapsible cavities 105 are disposed on opposite sides of the first body portion 101 and their openings are opposite to each other. The first body portion 101 forms an "I"-shaped cross-sectional shape in its length direction and width direction through the collapsible cavities 105.

[0028] In this embodiment, the first connecting groove 103 formed on the first body portion 101 is used to connect the first target structure, and the second connecting groove 104 on the second body portion 102 is used to connect the second target structure. In specific implementation, the shape and size of the first connecting groove 103 and the second connecting groove 104 can be flexibly customized according to the shape of the target structure. Furthermore, in this embodiment, the length and width directions of the first body portion 101 can be determined based on the length and width of the first body portion 101 during its fabrication. For ease of explanation, in this embodiment, the length direction of the first body portion 101 is... Figure 1 Let's take the x and y directions in the diagram as examples to illustrate.

[0029] According to the structure provided in this embodiment, in the novel double-forked intermediate cantilever structure provided in this embodiment, by providing open, mutually opposing collapsed cavities 105 on both sides of the first body part 101, the first body part 101 can form an I-shaped cross-sectional structure in both length and width directions. Since the double I-shaped structure can effectively disperse stress concentration and enhance load support stability, and in this embodiment, the collapsed cavity 105 is formed by forging, and the first body part 101 and the second body part 102 are also integrally forged. The first connecting groove 103 and the second connecting groove 104 form a groove-shaped structure with machining allowance when the first body part 101 and the second body part 102 are forged, and the allowance is removed by machining. This can significantly improve the overall stiffness and bending and torsional resistance of the novel double-forked intermediate cantilever structure in this embodiment, and can also maintain a lighter overall weight, which is far superior to the prior art.

[0030] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The first connecting groove 103 and the second connecting groove 104 extend in the same direction, and the first body portion 101 and the second body portion 102 cooperate in the depth direction of the collapsed cavity 105 to form an I-shaped structure. According to the structure provided in this embodiment, the cooperation of the first body portion 101 and the second body portion 102 to form an I-shaped structure is beneficial to further improve the overall structural strength of the two.

[0031] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 Both the first body portion 101 and the second body portion 102 are symmetrical geometric shapes, and their symmetry center planes coincide. According to the structure provided in this embodiment, the symmetrical first body portion 101 and the second body portion 102 with their symmetry center planes coincide can more effectively disperse stress and avoid stress concentration, which is beneficial to further improve the overall structural strength of the novel double-forked intermediate cantilever structure in this embodiment.

[0032] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The common center plane of symmetry of the first body part 101 and the second body part 102 is perpendicular to the depth direction of the collapsed cavity 105 and is located between adjacent collapsed cavities 105. According to the structure provided in this embodiment, the common center plane of symmetry of the first body part 101 and the second body part 102 is located between the two collapsed cavities 105, which can prevent the overall center of gravity of the novel double-forked intermediate cantilever structure in this embodiment from falling into the collapsed cavity 105, thereby further improving the overall structural strength of the novel double-forked intermediate cantilever structure in this embodiment.

[0033] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The first body portion 101 has a plurality of mounting holes 106 formed thereon, which are spaced apart along the edge of the first body portion 101; the second body portion 102 has shaft holes 108 formed thereon. In this embodiment, the shape of the mounting holes 106 is not limited, and can be set to circular, square, or polygonal shapes commonly used in the art. According to the structure provided in this embodiment, the mounting holes 106 distributed along the edge of the first body portion 101 can distribute the load to a greater extent, which is beneficial to further improving the structural strength of the novel double-forked intermediate cantilever structure in this embodiment; the shaft holes 108 are used for hinged connection with the target part to maintain the target part, such as a damping spring, at a certain swing angle to avoid mechanical interference.

[0034] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The mounting holes 106 on the first body part 101 are arranged in a triangular pattern. The axis of the shaft hole 108 on the second body part 102 is coplanar with the axis of the central mounting hole 106 on the first body part 101 and the symmetrical center plane of the two collapsed cavities 105. According to the structure provided in this embodiment, the triangularly distributed mounting holes 106 can make the novel double-forked intermediate cantilever structure in this embodiment more stably connected to the target structure. On the other hand, it is also conducive to further improving the overall structural strength of the novel double-forked intermediate cantilever structure in this embodiment. The axis of the shaft hole 108 is coplanar with the axis of the central mounting hole 106 on the first body part 101 and the symmetrical center plane of the two collapsed cavities 105, which makes the reaction force on the mounting hole 106 more reasonable and further improves the reliability of this intermediate cantilever structure.

[0035] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The first body portion 101 also has a limiting hole 107 coaxially connected to the mounting hole 106, and the limiting hole 107 has at least two different radial dimensions. For ease of explanation, this embodiment uses a circular hole 106 and a square hole 107 as an example. According to the structure provided in this embodiment, the limiting hole 107 is configured with two radial dimensions to form a non-rotational structure. Thus, as long as a nut of a corresponding shape is provided in the limiting hole 107, a bolt can be inserted and tightened from one side, which effectively reduces the installation difficulty of the novel double-forked intermediate cantilever structure in this embodiment.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. 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.
