Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile aluminum alloy front steering knuckle. Background Art

[0002] The steering knuckle is a key component in the automotive suspension system. Its functions include connecting the control arm assemblies, mounting the wheel hub bearings, connecting the wheel to the vehicle body, transmitting and bearing road loads from the tires, and mounting related wiring harnesses and other components. As the vehicle moves, the steering knuckle is subject to alternating loads, requiring high strength and durability in its design.

[0003] The commonly used forming processes for steering knuckles are ductile iron casting and alloy structural steel forging. Cast iron steering knuckles are often used in passenger cars. Products manufactured using this process have the advantages of higher material performance and lower cost, but also have the disadvantage of being very heavy. Forged steel steering knuckles are generally used in the commercial vehicle field. Compared with cast iron steering knuckles, forged steel materials have higher performance and a certain weight reduction effect, but have the disadvantage of being high cost.

[0004] Furthermore, existing technologies also allow the use of aluminum alloys for steering knuckle manufacturing. While aluminum alloys can achieve a certain degree of weight reduction compared to cast iron and traditional forged steel knuckles, this comes at a corresponding cost increase. The limited weight reduction and increased cost are both detrimental to achieving lightweighting of components and even the vehicle as a whole. Utility Model Content

[0039] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0040] Example 1

[0041] like Figures 1 to 4 A front steering knuckle of an automobile aluminum alloy includes a steering knuckle body 1, a weight-reducing cavity 2 is provided inside the steering knuckle body 1, and at least one sand discharge hole connected to the weight-reducing cavity 2 is opened through the steering knuckle body 1, and the two ends of the steering knuckle body 1 corresponding to the length direction are bent in opposite directions to form a bent structure, one of the bent structures is formed by bending one end of the steering knuckle body 1 toward the upper side, and the other bent structure is formed by bending the other end of the steering knuckle body 1 toward the lower side, and the two bent structures are fixedly connected with a reinforcing rib structure.

[0042] The beneficial effects of this embodiment are: by setting the weight-reducing cavity 2 in the steering knuckle body 1, the weight of the steering knuckle body 1 is reduced, thereby making it have a better lightweight effect and reducing material costs. At the same time, since the weight-reducing cavity 2 is opened in the steering knuckle body 1 in an integrated manner, the overall steering knuckle body 1 is self-contained and has better overall stability, avoiding the problem of difficult to ensure the strength of the connection when the weight-reducing cavity 2 is composed of multiple structures, and achieving a lightweight steering knuckle body 1 with better structural strength and structural stability. In addition, by fixing the reinforcing rib structure at both bending structures, the weight of the steering knuckle body 1 is reduced by the weight-reducing cavity 2, and the overall strength and rigidity of the steering knuckle body 1 are guaranteed by the reinforcing rib structure.

[0043] At the same time, since the weight-reducing cavity 2 reduces the thickness of the steering knuckle body 1, the steering knuckle body 1 formed during casting will be more accurate in various indicators and easier to form, which is beneficial to reducing casting defects and improving the processing quality of the entire steering knuckle body 1.

[0044] In addition, when making the steering knuckle body 1, a filling sand core will be set on the casting mold, so that the filling sand core can be used to form the weight-reducing cavity 2 when the material of the steering knuckle body 1 is cast, and the filling sand core will be wrapped inside it. After the casting of the steering knuckle body 1 is completed, the internal filling sand core can be discharged through the sand discharge hole provided on it and connected to the weight-reducing cavity 2, and finally a lightweight steering knuckle body 1 is obtained, thereby promoting the lightweight production of such parts.

[0045] As a specific solution of the above embodiment, the weight-reducing cavity 2 extends along the length direction of the steering knuckle body 1 to ensure that the steering knuckle body 1 has a sufficient degree of weight reduction, thereby improving the lightweight effect of such components and the entire vehicle.

[0046] Based on the above embodiment, the thickness of the two inner walls of the weight-reducing cavity 2 relative to each other in the extension direction of the steering knuckle body 1 is consistent. Specifically, the wall thickness of the upper and lower sides of the steering knuckle body 1 is consistent, and the wall thickness of the left and right sides is consistent, so as to achieve better structural stability of the steering knuckle body 1 and improve its strength and safety in use.

[0047] Specifically, the wall thickness of the top and bottom sides of the steering knuckle body 1 is a, which can be 3-7 mm, such as 5 mm. The wall thickness of the left and right sides of the steering knuckle body 1 is b, which can be 4-10 mm, such as 7 mm, where b ≥ a. Therefore, while the lower wall thickness reduces the weight of the steering knuckle body 1, the rib structure can be used to improve the rigidity and lightness of the steering knuckle body 1 along the thickness direction (the direction connecting the top and bottom sides). Furthermore, the greater wall thickness of the left and right sides of the steering knuckle body 1 can be used to increase the horizontal strength of the steering knuckle body 1, thereby improving the durability of the steering knuckle.

[0048] The thinner wall thickness a makes the steering knuckle body 1 more flexible in the up and down directions, which helps to improve the steering response speed and accuracy, allowing the driver to control the vehicle's driving direction more easily; the thicker wall thickness b enhances the rigidity of the steering knuckle body 1 in the left and right directions, which helps to reduce the roll angle caused by wheel deflection during steering, thereby improving the vehicle's driving stability.

[0049] Example 2

[0052] In the embodiment of the present invention, the upper reinforcing rib 5 is a solid structure to ensure its structural strength and increase the bending strength of the steering knuckle body 1. Moreover, the thickness of the upper reinforcing rib 5 is equal to the wall thickness of the upper side of the steering knuckle body 1 to ensure the stability of the casting process.

[0054] like Figures 1 to 4 On the basis of Examples 1 and 2, two upper reinforcing ribs 5 are arranged at intervals, and the two upper reinforcing ribs 5 are integrally formed on both sides of the upper side of the steering knuckle body 1 corresponding to the width direction, and a first assembly space structure is formed between the two upper reinforcing ribs 5.

[0055] The beneficial effect of adopting the preferred scheme in the above embodiment is that, by respectively arranging upper reinforcing ribs 5 at both ends of the upper side of the steering knuckle body 1, the steering knuckle body 1 can better resist deformation and damage when subjected to various forces and torques from the wheels and the road surface, thereby improving the durability and reliability of the steering knuckle body 1 and increasing the rigidity, thereby providing a strong guarantee for the driving stability and safety of the automobile. At the same time, the first assembly space structure formed between the two upper reinforcing ribs 5 facilitates the assembly of other parts. The two upper reinforcing ribs 5 are both located at the ends of the steering knuckle body 1, which can form the largest assembly space, making the assembly process smoother, reducing the difficulty and time of assembly, improving production efficiency, and making it easier to disassemble and install related parts, thereby reducing the difficulty and cost of maintenance.

[0060] In the embodiment of the present invention, the lower reinforcing rib 6 is a solid structure to ensure its structural strength and increase the bending strength of the steering knuckle body 1. Moreover, the thickness of the lower reinforcing rib 6 is equal to the wall thickness of the lower side of the steering knuckle body 1 to ensure the stability of the casting process.

[0061] Example 5

[0062] like Figures 1 to 4 On the basis of Examples 1-4, two lower reinforcing ribs 6 are arranged at intervals, and the two lower reinforcing ribs 6 are integrally formed on both sides of the upper side of the steering knuckle body 1 corresponding to the width direction, and a second assembly space structure is formed between the two lower reinforcing ribs 6.

[0063] The beneficial effect of adopting the preferred scheme in the above embodiment is that, by respectively arranging lower reinforcing ribs 6 at both ends of the upper side of the steering knuckle body 1, the steering knuckle body 1 can better resist deformation and damage when subjected to various forces and torques from the wheels and the road surface, thereby improving the durability and reliability of the steering knuckle body 1 and increasing the rigidity, thereby providing a strong guarantee for the driving stability and safety of the automobile. At the same time, the second assembly space structure formed between the two lower reinforcing ribs 6 facilitates the assembly of other parts. The two lower reinforcing ribs 6 are both located at the ends of the steering knuckle body 1, which can form the largest assembly space, making the assembly process smoother, reducing the difficulty and time of assembly, improving production efficiency, and making it easier to disassemble and install related parts, thereby reducing the difficulty and cost of maintenance.

[0067] The beneficial effect of adopting the preferred scheme in the above embodiment is that the opening of the vertical sand leakage hole 3 can further reduce the weight of the steering knuckle body 1 and improve the fuel economy and driving performance of the vehicle; at the same time, the vertical sand leakage hole 3 can be used to timely discharge the sand in the weight reduction cavity 2 after the steering knuckle body 1 is formed and the debris during use, so as to keep the weight reduction cavity 2 clean and unobstructed, thereby avoiding problems such as imbalance or vibration of the steering knuckle body 1 caused by sand accumulation; in addition, when the vehicle is driving, air can enter the weight reduction cavity 2 through the vertical sand leakage hole 3, providing additional ventilation and heat dissipation conditions for components such as the brake disc, thereby ensuring the normal operation of the steering knuckle body and extending its service life.

[0068] As a specific solution of the above embodiment, two vertical sand leakage holes 3 are provided, and are respectively opened at both ends of the steering knuckle body 1 in the length direction.

[0069] On the basis of the above embodiment, the vertical sand leakage hole 3 close to the other end of the steering knuckle body 1 is opened at the bending part of another bending structure to discharge the sand core filled in the weight-reducing cavity 2 after forming faster and more fully; at the same time, the vertical sand leakage hole 3 located at the corner can allow more air to enter the weight-reducing cavity 2 through the vertical sand leakage hole 3 during the driving process of the vehicle, providing additional ventilation and heat dissipation conditions for components such as the brake disc, thereby ensuring the normal operation of the steering knuckle body and extending its service life.

[0073] The beneficial effects of the preferred solution in the above embodiment are that the provision of the transverse sand leakage holes 4 further reduces the weight of the steering knuckle body 1, improving the vehicle's fuel economy and driving performance. Furthermore, the transverse sand leakage holes 4 allow for the timely removal of sand and debris from the weight-reducing cavity 2 after the steering knuckle body 1 is formed, maintaining a clean and unobstructed cavity 2, thereby preventing problems such as imbalance or vibration of the steering knuckle body 1 caused by sand accumulation. Furthermore, when the vehicle is driving, air can enter the weight-reducing cavity 2 through the transverse sand leakage holes 4, providing additional ventilation and heat dissipation for components such as the brake disc, thereby ensuring the proper operation of the steering knuckle body and extending its service life.

[0074] Based on the above embodiment, second hole ribs 41 are integrally formed at both openings of each transverse sand leakage hole 4. The second hole ribs 41 have a thickness of 2-3 mm and a width of 2-4 mm to improve local structural strength.
