Description

Technical area

[0001] The present utility model relates to the technical field of tie rods, and in particular to a tie rod for vehicle technology. State of the art

[0002] The tie rod is a crucial component in a vehicle's steering system, directly impacting steering stability, operational safety, and tire life. Tie rods are divided into two categories: straight tie rods and transverse tie rods. The straight tie rod transmits the steering arm's movement to the steering knuckle; the transverse tie rod forms the base of the steering linkage and is a key component ensuring proper synchronization of the left and right steering wheels.

[0003] Patent number CN213168279U describes a tie rod for automotive engineering. This tie rod is equipped with an extension rod, and its overall length can be adjusted as needed to prevent the vehicle's front compartment from being too small for installation. This ensures optimal use of the vehicle's front compartment, thus improving design flexibility.

[0004] However, the technical solution described above still has some problems. Adjusting the overall length involves moving the extendable projection out of the extendable slot. When the projection is pulled out of the slot, the ends of the left drawbar and extension rod are hollow, compromising their structural integrity. This makes it easy to damage the connection points between the left drawbar, extension rod, and right drawbar. Therefore, a vehicle-specific drawbar is required to address the problems of the technical solution described above. Content of the utility model

Examples of implementation

[0014] The present utility model is described in more detail below with reference to the attached figures.

[0015] As in Fig. 1 to Fig.As shown in Figure 7, a drawbar for automotive engineering comprises a central sleeve tube 10. Several reinforcing rods 11 are rigidly connected inside the central sleeve tube 10. A support opening I 111 is formed on the outer surface of each of the several reinforcing rods 11. Two drawbars 20 are slidably connected inside the central sleeve tube 10. A receiving groove 201 is formed on each of the two drawbars 20. The reinforcing rods 11 are located inside the receiving grooves 201. The width of the receiving grooves 201 is adapted to the diameter of the reinforcing rods 11. Several fixing holes 202 are formed on each of the two drawbars 20. A drawbar reinforcement assembly is arranged on each of the two drawbars 20. The tie rod reinforcement assemblies serve to cover the receiving grooves 201 in order to increase the structural strength of the tie rods 20.Ball-end socket assemblies 40 are connected to the ends of each of the two tie rods 20. Several connecting openings 101 are formed on the central sleeve tube 10. The connecting openings 101 correspond one-to-one with the support openings I 111. A support rod I 30 is inserted into each of the connecting openings 101. The support rods I 30 pass through the interior of the support openings I 111. The support rods I 30 and the support openings I 111 correspond one-to-one. The support rods I 30 and the reinforcing rods 11 are perpendicular to each other. The support rods I 30 are inserted into the interior of the fixing holes 202. The diameter of the support rods I 30 is adapted to the diameter of the fixing holes 202. A mounting plate 31 is connected to the ends of the several support rods I 30. A fixing assembly is connected to the several support rods I 30.The fixing assembly serves to fix the support rods I 30 so that the support rods I 30 are inserted stably into the interior of the support openings I 111 and the fixing holes 202.

[0016] In the normal state, the centers of the fixing holes 202, the support openings I 111, and the connecting openings 101 are on the same horizontal plane. If the overall length of this tie rod needs to be adjusted, the tie rod 20 is pulled out from inside the central sleeve tube 10 by a suitable length. The ball-end socket assembly 40 is positioned appropriately. Then, the support rods I 30 are passed through the inside of the connecting openings 101 and the support openings I 111, and the mounting plate 31 is placed against the central sleeve tube 10. At this point, a certain number of support rods I 30 pass through the inside of the fixing holes 202. The fixing assembly is then connected to the support rods I 30 to lock them in place, preventing any further movement.Simultaneously, the tie rod 20 is fixed in place so that it can no longer be moved. This completes the adjustment of the overall length of this tie rod. At this point, a cross-bracing structure forms between the multiple support rods I 30 and the multiple reinforcing rods 11, supporting the interior of the central sleeve tube 10 and ensuring its structural stability. The reinforcing assembly is then connected to the tie rod 20 to increase its overall structural strength.

[0017] It should be noted that the distance between two adjacent support openings I 111, the distance between two adjacent fixing holes 202 and the distance between two adjacent connecting openings 101 are the same in order to facilitate the subsequent connecting and fixing operations.

[0018] The tie rod reinforcement assemblies comprise reinforcement blocks 21, which are arranged inside the receiving channels 201. Support openings III 211 are formed on the sides of the reinforcement blocks 21. Support plug rods II 22 are inserted into the interior of the support openings III 211. The support plug rods II 22 pass through the interior of the fixing plug holes 202. Limit blocks 23 are firmly connected to the ends of the support plug rods II 22. Connecting nuts II 24 are screwed onto the outer surfaces of the ends of the support plug rods II 22 that are furthest from the limit blocks 23. Fixing blocks 25 abut the outer surfaces of the tie rods 20. Support openings IV 251 are formed on the sides of the fixing blocks 25. The support plug rods II 22 pass through the interior of the support openings IV 251.

[0019] After the tie rod 20 has been adjusted to a suitable position, part of the fixing holes 202 is accessible from the outside. A suitable number of reinforcement assemblies are selected. The reinforcement blocks 21 are placed inside the receiving channel 201, and the support openings III 211 are positioned at the fixing holes 202. Then, the support rods II 22 are passed through the interior of the support openings III 211 and the fixing holes 202, and the limit blocks 23 are positioned against the tie rod 20. Next, the support openings IV 251 are slid onto the surfaces of the support rods II 22, and the fixing blocks 25 are positioned against the tie rod 20. Finally, the connecting nuts II 24 are screwed onto the ends of the support rods II 22, and the connecting nuts II 24 are tightened against the fixing blocks 25. This secures the support rods II 22.At this point, the reinforcement blocks 21 are fixed inside the receiving trough 201, and the receiving trough 201 is covered, thereby increasing the structural strength of the tie rod 20.

[0020] The fixing assembly comprises a fixing plate 32, which rests against the outer surface of the central sleeve tube 10. Several support openings II 321 are formed on one side of the fixing plate 32. The number of support openings II 321 corresponds to the number of support openings I 111. The support rods I 30 pass through the interior of the support openings II 321. The support rods I 30 and the support openings II 321 correspond one-to-one. Connecting nuts I 33 are screwed onto the outer surfaces of the ends of the multiple support rods I 30 that are furthest from the mounting plate 31.

[0021] After the support rods I 30 have been passed through the interior of the connecting openings 101 and the support openings I 111, the fixing plate 32 is placed against the outer surface of the central sleeve tube 10, and the support rods I 30 are passed through the interior of the support openings II 321. At this point, the support rods I 30 pass through the interior of the fixing holes 202. Then, the connecting nuts I 33 are screwed onto the outer surfaces of the support rods I 30, and the connecting nuts I 33 are firmly pressed against the fixing plate 32. This fixes the support rods I 30, and the fixing of the pull rod 20 is complete.

[0022] It should be noted that the distance between two adjacent support openings II 321 is equal to the distance between two adjacent support openings I 111.

[0023] Lubrication assemblies are arranged on the tie rods 20. These assemblies serve to lubricate the connection points between the ball-joint socket assemblies 40 and the tie rods 20. The lubrication assemblies comprise oil reservoirs 26, which are connected to the outer circumferential surfaces of the tie rods 20. Capillaries 27 are connected to the oil reservoirs 26. The ends of the capillaries 27 correspond to the positions of the connection points between the ball-joint socket assemblies 40 and the tie rods 20.

[0024] The oil reservoirs 26 contain lubricating grease. The capillaries 27 utilize the capillary phenomenon, allowing the lubricating grease to slowly and continuously penetrate from the oil reservoirs 26 into the connection points between the ball joint assemblies 40 and the tie rods 20 under capillary force, without the need for an external driving force to lubricate the connection points between the ball joint assemblies 40 and the tie rods 20.

[0025] The ball joint socket assemblies 40 comprise adjusting screws 41, which are screwed to the ends of the tie rods 20. Ball joint sockets 42 are connected to the ends of the adjusting screws 41. Adjusting nuts 43 are firmly connected to the ends of the tie rods 20. The adjusting screws 41 are screwed to the adjusting nuts 43.

[0026] By turning the adjusting screws 41, the positions of the ball joint cups 42 can be finely adjusted, allowing the ball joint cups 42 to be better connected to the external connection structure. The adjusting screws 41 are screwed to the tie rods 20 and the adjusting nuts 43. The double threaded connection ensures the positional stability of the adjusting screws 41.

[0027] It should be noted that the capillaries 27 are mounted to the adjusting nuts 43 by means of fixing clamps, and the ends of the capillaries 27 correspond to the positions of the connection points between the adjusting screws 41 and the adjusting nuts 43. This allows the capillaries 27 to reliably transport the lubricating grease to the connection points between the adjusting screws 41 and the adjusting nuts 43 for lubrication. This lubrication ensures that the lubrication condition of the threaded connection points between the adjusting screws 41 and the adjusting nuts 43 is always maintained at an optimal level, reducing frictional resistance and effectively minimizing wear and energy loss due to friction. At the same time, it avoids the safety risks that can arise from untimely manual lubrication maintenance.

[0028] A nanoceramic coating is applied to the outer surface of the central sleeve tube 10, the tie rods 20, and the ball joint cups 42. The nanoceramic coatings serve to improve the wear resistance and corrosion resistance of the central sleeve tube 10, the tie rods 20, and the ball joint cups 42, and to ensure their service life.
