Description

Technical Field

[0001] The utility model relates to the technical field of automobile engineering, in particular to a thrust rod bracket. Background Art

[0002] As a key component of the air suspension, the thrust rod bracket plays a vital role in connecting the frame and the axle, transmitting driving force and braking force. The design of the thrust rod bracket takes into account the high requirements of modern automobiles for handling, stability and safety. It adopts high-strength materials and precision manufacturing processes to ensure stable installation and reliable force transmission. The existence of the thrust rod bracket not only ensures the reasonable movement trajectory between the axle and the frame, but also greatly attenuates the vibration of the vehicle, providing a more comfortable driving experience. In addition, the thrust rod bracket can maintain stable performance for a long time, reduce the frequency of maintenance and replacement, and provide a strong guarantee for the safety and stable driving of the vehicle. Therefore, the thrust rod bracket plays an important role in the air suspension system and is an indispensable part of the suspension system of modern automobiles.

[0003] The existing thrust rod bracket is composed of a frame mounting part and a thrust rod mounting part. The frame mounting part is designed with multiple rows of mounting holes, which increase in thickness from top to bottom, in order to ensure a stable and reliable connection between the thrust rod bracket and the frame. The thrust rod mounting part is responsible for connecting the thrust rod to ensure smooth transmission of force and motion.

[0004] However, in actual applications, the forces on the mounting holes in the same row are not the same. In order to ensure a stable and reliable connection between the thrust rod bracket and the frame, the hole depth is usually designed according to the mounting hole with the greatest force, which will increase the overall weight of the thrust rod bracket and does not meet the requirements of lightweight design of the vehicle. Summary of the invention

[0005] The utility model aims at the problem that the hole depth of some mounting holes is redundant, resulting in the overweight of the thrust rod bracket, and provides a thrust rod bracket which can realize the hole depth design of the mounting holes according to the required strength and will not cause the thrust rod bracket to be overweight.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is a thrust rod bracket, including a connecting part, a weight-reducing hole is arranged on the connecting part, one end of the connecting part is connected to a frame mounting part, a boss is arranged on the frame mounting part, a mounting hole is arranged on the boss, the hole depth of the mounting hole can just meet the installation strength requirement, and the other end of the connecting part is connected to the thrust rod mounting part. After finite element analysis and topological optimization, the installation strength required for the mounting holes of the thrust rod bracket at different positions can be determined. According to these strength requirements, the thickness of the boss is optimized to ensure that the hole depth of the mounting hole can meet the strength requirement and avoid adding unnecessary materials. At the same time, the weight-reducing hole is arranged at a position where the force is small and the impact on the performance of the parts is limited, which can significantly reduce the overall weight of the thrust rod bracket. Therefore, the thrust rod bracket not only ensures the required strength, but also achieves lightweight by reducing the excess weight at the mounting holes and the weight-reducing holes, which fully meets the requirements of modern automobiles for lightweight design.

[0007] Preferably, there are three rows of mounting holes, the first row of mounting holes is far away from the connection part, the third row of mounting holes is close to the connection part, and the second row of mounting holes is between the first row of mounting holes and the third row of mounting holes. Multiple rows of mounting holes can disperse the force more effectively, evenly distribute the load to different parts of the thrust rod bracket, reduce the situation of excessive force on a single point, and enhance the structural stability and durability of the thrust rod bracket.

[0008] Preferably, the first row of mounting holes includes six mounting holes, the second row of mounting holes includes eight mounting holes, and the third row of mounting holes includes nine mounting holes. Multiple mounting holes not only enhance the mounting strength, effectively disperse the force, and improve the structural stability, but also allow for flexible selection of appropriate mounting holes according to different application scenarios and specification requirements.

[0009] Preferably, a weight reduction groove is further provided on the frame mounting portion, and the weight reduction groove is located between the third mounting hole and the fourth mounting hole in the first row of mounting holes. The weight reduction groove can further reduce the weight of the thrust rod bracket, achieving a more lightweight effect.

[0010] Preferably, the hole depths of all the mounting holes in the first row of mounting holes are the same, and the hole depths are between 19.5 and 23 mm; the hole depths of the third mounting hole to the sixth mounting hole in the second row of mounting holes are the same, and the hole depths are between 19.5 and 23 mm, and the hole depths of the remaining mounting holes in the second row of mounting holes are the same, and the hole depths are between 38 and 51.5 mm; the hole depth of the fifth mounting hole in the third row of mounting holes is between 19.5 and 23 mm, the hole depths of the second mounting hole and the eighth mounting hole in the third row of mounting holes are the same, and the hole depths are between 38 and 51.5 mm, and the hole depths of the remaining mounting holes in the third row of mounting holes are the same, and the hole depths are between 23.5 and 37.5 mm. The hole depths of all mounting holes have been subjected to finite element analysis and topological optimization to ensure the installation strength while achieving effective reduction of excess weight, which fully meets the requirements of lightweight design of automobiles.

[0011] Preferably, the connection portion includes a connection plate, which is an inverted triangle with a wide top and a narrow bottom. The wider side of the connection plate is fixedly connected to the frame mounting portion, and the narrower side of the connection plate is fixedly connected to the thrust rod mounting portion. The connection plate is arranged in an inverted triangle with a wide top and a narrow bottom. This structural layout fits the force characteristics of the thrust rod bracket, and can effectively reduce the weight of the thrust rod bracket through reasonable material distribution while ensuring the strength of the thrust rod bracket, thereby improving the lightweight effect of the overall structure.

[0012] Preferably, a reinforcing rib is provided on the connecting plate, the upper end of the reinforcing rib is connected to the frame mounting portion, the lower end of the reinforcing rib is connected to the thrust rod mounting portion, and the reinforcing rib is Y-shaped as a whole. The reinforcing rib is arranged in a Y-shape, closely matching the shape of the connecting plate, effectively enhancing the connection strength of the thrust rod bracket, and improving the stability and reliability of the overall structure.

[0013] Preferably, the height of the reinforcing rib increases gradually from the upper end of the reinforcing rib to the lower end of the reinforcing rib. According to the stress of the thrust rod bracket, the height of the reinforcing rib increases gradually from the upper end of the reinforcing rib to the lower end of the reinforcing rib, which ensures that the reinforcing rib can provide sufficient strength support and avoids adding redundant materials, thus achieving dual optimization of strength and lightness.

[0014] Preferably, the weight-reducing hole is an inverted triangle, and a large rounded corner is provided at the corner of the weight-reducing hole. The weight-reducing hole is an inverted triangle, which meets the stress conditions of the thrust rod bracket. At the same time, a large rounded corner is provided at the corner of the weight-reducing hole, which effectively avoids stress concentration and improves the durability and reliability of the thrust rod bracket.

[0015] Preferably, the thrust rod mounting portion has a C-shaped cross section, and the thrust rod mounting portion includes a first mounting arm and a second mounting arm, the first mounting arm is provided with a first connecting hole, and the second mounting arm is provided with a second connecting hole. The thrust rod mounting portion has a C-shaped cross section, which helps to avoid the thrust rod ball head and facilitates installation and positioning. The first connecting hole and the second connecting hole are used to connect firmly with the thrust rod, ensuring smooth and reliable thrust transmission.

[0016] It can be seen from the above technical solutions that the advantages of the utility model are: through finite element analysis and topological optimization, the required installation strength of the mounting holes of the thrust rod bracket at different positions can be determined. According to these strength requirements, the thickness of the boss is optimized to ensure that the hole depth of the mounting hole can meet the strength requirements while avoiding the addition of excess material. At the same time, weight-reducing holes and weight-reducing grooves are set at positions with less force and limited impact on part performance, which can significantly reduce the overall weight of the thrust rod bracket. In summary, the thrust rod bracket not only ensures the required strength, but also achieves a lightweight design by reducing excess weight, which meets the needs of modern automobiles for lightweight and high performance.

[0029] The first row of bosses includes six bosses. From left to right, the first three bosses are close to the left side of the frame mounting portion 100, and the last three bosses are close to the right side of the frame mounting portion 100, and the first three bosses and the last three bosses are symmetrically distributed. All boss heights of the first row of bosses are the same, and the hole depths of all mounting holes 110 of the first row of mounting holes 111 are also the same, and the hole depths are between 19.5 and 23 mm. In addition, a weight reduction groove 120 is also provided on the frame mounting portion 100, and the weight reduction groove 120 is located between the third mounting hole 110 and the fourth mounting hole 110 of the first row of mounting holes 111, and a large fillet is provided at the corner of the weight reduction groove 120.

At the same time, the height of the reinforcing rib 220 gradually increases from the upper end of the reinforcing rib 220 to the lower end of the reinforcing rib 220. Similarly, the two reinforcing ribs 220 on the side facing the frame 2 are also located at the edge of the connecting plate 210, and are symmetrically arranged about the weight-reducing hole 211, forming a Y shape as a whole. Meanwhile, the height of the reinforcing rib 220 gradually increases from the upper end of the reinforcing rib 220 to the lower end of the reinforcing rib 220.

[0035] The position and height of the reinforcing rib 220 are obtained by finite element analysis and topological optimization, ensuring that the reinforcing rib 220 can meet the strength requirements while avoiding the addition of redundant materials and meeting the lightweight design requirements. The position and size of the weight-reducing hole 211 are also obtained by finite element analysis and topological optimization. The weight-reducing hole 211 is set at a position with less force and relatively limited impact on the performance of the part, thereby effectively reducing the overall weight of the thrust rod bracket 1.

The first mounting arm 310 is provided with a first connecting hole 330, and the second mounting arm 320 is provided with a second connecting hole 340. The thrust rod 3 is connected to the thrust rod mounting portion 300 by passing the first connecting hole 330 and the second connecting hole 340 through a ball pin.

[0037] In this specific embodiment, the thrust rod bracket 1 is formed by integral casting of high-performance aluminum alloy material HX205.1, and the weight of the finished product reaches 12.8 kg, which is 7.2 kg lighter than the original solution, and the lightweight degree reaches 36%.

[0038] It can be seen from the above embodiments that the beneficial effect of the utility model is that, through finite element analysis and topological optimization, the required installation strength of the mounting holes of the thrust rod bracket at different positions can be determined. According to these strength requirements, the thickness of the boss is optimized to ensure that the hole depth of the mounting hole can meet the strength requirements while avoiding the addition of excess material. At the same time, by setting weight-reducing holes and weight-reducing grooves at positions where the force is small and the impact on the performance of the parts is limited, the overall weight of the thrust rod bracket can be significantly reduced. In summary, the thrust rod bracket not only ensures the required strength, but also achieves a lightweight design by reducing excess weight, which meets the needs of modern automobiles for lightweight and high performance.
