Description

Technical Field

[0001] This utility model relates to the technical field of automotive chassis components, specifically a crossbeam tie rod welding assembly. Background Technology

[0002] The crossbeam tie rod welding assembly is a key component of the automobile frame, used to connect various parts of the frame, transmit longitudinal and lateral forces during vehicle operation, and provide a mounting base for systems such as suspension.

[0003] The existing crossbeam tie rod welded assembly still has the following problems when in use: the overall strength distribution of each component is uneven after welding, and local deformation and cracking are likely to occur under long-term load; the compatibility between components is poor, and positioning is difficult during assembly, which affects production efficiency and connection accuracy; stress concentration is obvious, and force transmission is not smooth under complex road conditions, which reduces the service life of the assembly and the whole vehicle and driving safety. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a welded beam tie rod assembly. By incorporating positioning pins, reinforcing rib structures, and specific connection methods, it solves the problems of uneven strength, poor adaptability, and stress concentration mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crossbeam tie rod welding assembly, including a crossbeam, a left tie rod assembly, a right tie rod assembly, a positioning pin, and an intermediate connecting seat.

[0006] The crossbeam is a long, rigid structure that serves as a basic load-bearing component. It connects the left and right tie rod assemblies, providing a support frame for the whole structure. It can distribute and transmit longitudinal and lateral forces during vehicle movement. High-strength steel is used to ensure structural strength and rigidity.

[0007] The left tie rod assembly includes a left main tie rod, a left connecting lug, a left crossbeam connecting reinforcement, a left tie rod hole reinforcement, a left tie rod longitudinal reinforcement, and a left lug side reinforcement. The left main tie rod is welded to the crossbeam. The left crossbeam connecting reinforcement, left tie rod hole reinforcement, left tie rod longitudinal reinforcement, and left lug side reinforcement are evenly distributed on the left connecting lug. The left connecting lug is used to connect to the external frame or suspension assembly. The various reinforcements are distributed in different parts of the assembly, enhancing the strength and fatigue resistance of the left tie rod assembly from multiple dimensions and preventing deformation under load.

[0008] The right tie rod assembly includes a right main tie rod, a right connecting lug, a right crossbeam connecting reinforcement, a right tie rod hole reinforcement, a right tie rod longitudinal reinforcement, and a right lug side reinforcement. The right main tie rod is welded to the crossbeam. The right crossbeam connecting reinforcement, the right tie rod hole reinforcement, the right tie rod longitudinal reinforcement, and the right lug side reinforcement are evenly distributed on the right connecting lug. The right connecting lug is used for external connection. The reinforcements work together to improve the strength of the right tie rod assembly and are symmetrically arranged with the left tie rod assembly to ensure balanced stress on the vehicle.

[0009] The locating pins are cylindrical and are inserted into the locating holes of the crossbeam and the left tie rod assembly, and the crossbeam and the right tie rod assembly, to achieve precise positioning of each component during installation, improve assembly accuracy, facilitate welding and subsequent maintenance, and ensure accurate relative positions between components.

[0010] The intermediate connecting seat consists of a connecting seat base and a connecting seat positioning protrusion. The connecting seat base is welded to the middle of the crossbeam, and the connecting seat positioning protrusion is used to adapt and connect with the external frame or other core components, thereby enhancing the connection stability between the assembly and the external structure and distributing the force on the crossbeam.

[0011] As a further improvement of this utility model: after the left tie rod assembly, the right tie rod assembly and the crossbeam are pre-positioned by the positioning pins, they are welded and fixed by the full welding process. The positioning pins ensure accurate connection position, and the full welding improves connection strength, making force transmission stable and reliable, and effectively resisting vibration and impact during vehicle operation.

[0012] As a further improvement of this utility model, the reinforcing rib structures of the left tie rod assembly and the right tie rod assembly strengthen the components from the directions of crossbeam connection, hole position, longitudinal direction and ear plate side, forming a three-dimensional reinforcement system, which greatly improves the component's resistance to deformation.

[0013] As a further improvement of this utility model: the positioning protrusion of the intermediate connecting seat is adapted to the external frame or core component, and an interference fit or bolt connection is adopted to ensure a stable connection between the assembly and the external structure, and to distribute the load of the crossbeam while transmitting force.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, precise pre-positioning is achieved through positioning pins, and the full welding process ensures the accuracy of the connection position and the connection strength of each component, solving the problems of poor assembly compatibility and uneven connection strength, making force transmission more stable and effectively resisting the vibration and impact of vehicle driving.

[0016] 2. In this utility model, the multi-part reinforcing rib structure of the left and right tie rod assemblies forms a three-dimensional reinforcement system, which, together with the intermediate connecting seat, disperses stress, solves the stress concentration problem, improves the overall strength and fatigue resistance of the assembly, extends its service life, and ensures the safety of vehicle operation.

[0024] It should be noted that the selection of steel materials and welding processes are existing technologies and common knowledge to those in this field, and will not be elaborated upon here.

[0025] Please see Figures 1-3 In this embodiment of the utility model, a crossbeam tie rod welding assembly includes a crossbeam 1, a left tie rod assembly 2, a right tie rod assembly 3, a positioning pin 4, and an intermediate connecting seat 5.

[0026] The crossbeam 1 is a long, rigid structure that serves as the basic load-bearing component. It connects the left tie rod assembly 2 and the right tie rod assembly 3, providing a support frame for the whole structure. It can distribute and transmit longitudinal and lateral forces during vehicle operation. High-strength steel is used to ensure structural strength and rigidity.

[0027] The left tie rod assembly 2 includes a left main tie rod 25, a left connecting lug plate 23, a left crossbeam connecting reinforcing rib 21, a left tie rod hole reinforcing rib 22, a left tie rod longitudinal reinforcing rib 24, and a left lug plate side reinforcing rib 26. The left main tie rod 25 is welded to the crossbeam 1, and the left connecting lug plate 23 is used to connect to the external frame or suspension assembly. The reinforcing ribs are distributed in different parts of the assembly, enhancing the strength and fatigue resistance of the left tie rod assembly 2 from multiple dimensions and preventing deformation under load.

[0028] The right tie rod assembly 3 includes a right main tie rod 35, a right connecting lug plate 33, a right crossbeam connecting reinforcing rib 31, a right tie rod hole reinforcing rib 32, a right tie rod longitudinal reinforcing rib 34, and a right lug plate side reinforcing rib 36. The right main tie rod 35 is welded to the crossbeam 1, and the right connecting lug plate 33 is used for external connection. The reinforcing ribs work together to improve the strength of the right tie rod assembly 3, and are symmetrically arranged with the left tie rod assembly 2 to ensure balanced force distribution on the vehicle.

[0029] The positioning pin 4 is cylindrical and is inserted into the positioning holes of the crossbeam 1 and the left tie rod assembly 2, and the crossbeam 1 and the right tie rod assembly 3, so as to achieve precise positioning of each component during installation, improve assembly accuracy, facilitate welding and subsequent maintenance, and ensure accurate relative positions between components.

[0030] The intermediate connecting seat 5 consists of a connecting seat base 51 and a connecting seat positioning protrusion 52. The connecting seat base 51 is welded to the middle of the crossbeam 1, and the connecting seat positioning protrusion 52 is used to adapt and connect with the external frame or other core components, thereby enhancing the connection stability between the assembly and the external structure and dispersing the force on the crossbeam 1.

[0031] After the left tie rod assembly 2 and the right tie rod assembly 3 are pre-positioned with the crossbeam 1 by the positioning pin 4, they are welded and fixed by a full welding process. The positioning pin 4 ensures accurate connection position, and the full welding improves connection strength, making force transmission stable and reliable, and effectively resisting vibration and impact during vehicle operation.

[0032] The reinforcing ribs of the left tie rod assembly 2 and the right tie rod assembly 3 strengthen the assemblies from the directions of crossbeam connection, hole position, longitudinal direction and ear plate side, forming a three-dimensional reinforcement system, which greatly improves the deformation resistance of the assemblies.

[0033] The intermediate connecting seat 5 has a connecting seat positioning protrusion 52 that is adapted to the external frame or core components. It adopts an interference fit or bolt connection method to ensure a stable connection between the assembly and the external structure, and to distribute the load of the crossbeam 1 while transmitting force.

[0034] The working principle of this utility model is as follows: During assembly, the positioning pin 4 is first inserted into the positioning hole of the crossbeam 1, and then the corresponding holes of the left tie rod assembly 2 and the right tie rod assembly 3 are fitted into the positioning pin 4 to complete the pre-positioning and ensure the accurate position of each component; then, the welding joints of the left tie rod assembly 2 and the crossbeam 1, and the right tie rod assembly 3 and the crossbeam 1 are fully welded to form a stable connection; finally, the connecting seat base 51 of the intermediate connecting seat 5 is welded to the middle of the crossbeam 1, and the positioning protrusion 52 of the connecting seat is reserved for external adaptation connection structure to complete the assembly assembly. When the vehicle is driving, the longitudinal and lateral forces of the road surface are transmitted to the left connecting ear plate 23 and the right connecting ear plate 33 through the suspension system, and then transmitted to the crossbeam 1 through the left main tie rod 25 and the right main tie rod 35. The crossbeam 1 distributes the force to the main longitudinal beam of the frame through the intermediate connecting seat 5. During the process, the reinforcing ribs enhance the deformation resistance of the components, the positioning pin 4 ensures the stability of the force transmission path, and the intermediate connecting seat 5 strengthens the connection between the crossbeam and the frame, jointly improving the vehicle's driving stability and safety, and extending the service life of the assembly.
