[0002] The steering rod is a key structure in vehicle steering. It is mainly composed of a rod and a joint, connecting the steering knuckle and the steering gear to facilitate the steering of the wheels.

[0003] Most of the existing steering rods are of fixed length, which cannot meet the needs of heavy vehicles, such as integral frame support transporters, heavy flatbed transporters and multi-wheel mining vehicles in open-pit mines. Due to the large steering torque of heavy wheels and high requirements for steering accuracy, multiple steering rods are required for installation, and fixed-length steering rods cannot meet the needs.

[0004] For example, a steering tie rod with application number 202220832641.3 includes a tie rod body and a joint. Connecting ends are provided at both ends of the tie rod body, screw holes are provided on the connecting ends, locking grooves are provided outside the connecting ends, a joint is installed on the connecting ends, a locking device is provided on the street, the joint is installed in the screw hole, and the locking device is inserted into the locking groove to securely connect the joint and the tie rod body.

[0005] After the joint is installed on the tie rod body, the above patent fixes it through a locking device to complete the installation of the joint on the tie rod body, which is convenient for installation and disassembly, and increases the force-bearing area compared to welding. However, the patent cannot change the length of the steering tie rod, and the steering accuracy is not high. Utility Model Content

[0006] The utility model aims to solve the above problems existing in the prior art and provides an automobile steering tie rod assembly which is easy to adjust the length.

[0007] The utility model can be implemented through the following technical scheme: an adjustable automobile steering tie rod assembly, including a mounting rod and a threaded rod, a ball head assembly is installed at one end of the mounting rod, a threaded groove is provided at the other end of the mounting rod, the threaded rod is a cylinder, one end of the threaded rod is processed with threads, and the other end of the threaded rod is processed with a ball head pin, and the ball head pin is installed in a ball seat.

[0008] In the above-mentioned adjustable automobile steering tie rod assembly, a fixing seat is arranged outside the threaded groove.

[0009] In the above-mentioned adjustable automobile steering tie rod assembly, an opening is provided on the fixing seat, and the opening divides the fixing seat into blade one and blade two.

[0010] In the above-mentioned adjustable automobile steering tie rod assembly, a guide hole is formed on the first blade, and a screw hole is formed on the second blade.

[0011] In the above-mentioned adjustable automobile steering tie rod assembly, the thickness of the second blade is greater than that of the first blade.

[0012] In the above-mentioned adjustable automobile steering tie rod assembly, a locking nut is installed on the thread, and the locking nut fits the mounting rod.

[0013] In the above-mentioned adjustable automobile steering tie rod assembly, a spline section is provided at the front end of the thread.

[0014] Compared with the prior art, the advantage of the utility model is that the steering rod with an original fixed length is divided into two parts, one part is a threaded rod with threads, and the other part is a mounting rod with a threaded groove. The length of the steering rod is adjusted by applying force to rotate the threaded rod at the spline groove, and locked by a locking nut. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figures 1 to 4 As shown, the utility model can be implemented through the following embodiments: an adjustable automobile steering rod assembly includes a mounting rod 1 and a threaded rod 2, a ball head assembly 3 is installed at one end of the mounting rod 1, a thread groove 11 is provided at the other end of the mounting rod 1, the threaded rod 2 is a cylinder as a whole, a thread 21 is processed at one end of the threaded rod 2, a ball head pin 22 is processed at the other end of the threaded rod 2, and the ball head pin 22 is installed in the ball seat 4.

[0022] The steering rod is divided into two parts: a mounting rod 1 and a threaded rod 2. The threaded rod 2 can adjust its length in the mounting rod 1 by rotating. The threaded connection ensures that there will be no relative sliding between the threaded rod 2 and the mounting rod 1. The cylindrical threaded rod 2 ensures that the assembly will not be affected after rotation, making it easy to adjust the length.

[0023] like Figure 1 and Figure 3 As shown, a fixing seat 5 is arranged outside the thread groove 11. The fixing seat 5 is used to lock the threaded rod 2 installed in the thread groove 11 to prevent the threaded rod 2 from being vibrated and moving, causing the threaded rod 2 to be separated from the mounting rod 1.

[0024] like Figure 4 As shown, the fixing seat 5 is provided with an opening 51, and the opening 51 divides the fixing seat 5 into a blade 1 52 and a blade 2 53. The appearance of the opening 51 divides the fixing seat 5 into a blade 1 52 and a blade 2 53, so that the fixing seat 5 can be deformed to a certain extent, which is convenient for the installation and locking of the threaded rod 2.

[0025] like Figure 4 As shown, a guide hole 521 is provided on the blade 1 52, and a screw hole 531 is provided on the blade 2 53. The guide hole 521 is used to guide the bolt to be inserted into the fixing seat 5, and the screw hole 531 is used to connect the bolt with the fixing seat 5, and the blade 1 52 and the blade 2 53 are fitted together by the cooperation of the bolt and nut, thereby completing the locking of the threaded rod 2.

[0026] like Figure 4 As shown, the thickness of blade 2 53 is greater than that of blade 1 52. The thickness of blade 2 53 is greater than that of blade 1 52, so that the position of opening 51 is in an eccentric position, so that when the threaded rod 2 is inserted into the fixing seat 5, the deviation between the guide hole 521 and the screw hole 531 is not large, which is convenient for bolt insertion. At the same time, the thick blade 2 53 means that the screw hole 531 is long, and blade 2 53 is not easily damaged when the bolt is installed; the thin thickness of blade 1 52 is convenient for pulling blade 1 52 when the nut is rotated to complete the locking of the threaded rod 2.

[0027] like Figure 1 As shown, a locking nut 6 is installed on the thread 21, and the locking nut 6 fits the mounting rod 1. The locking nut 6 is used as a limiting structure to prevent the thread 21 from loosening when the threaded rod 2 is vibrated, resulting in an increase in the length of the steering rod.

[0028] like Figure 1 and Figure 2 As shown, a spline section 23 is provided at the front end of the thread 21. The spline section 23 facilitates the staff to apply force to rotate the threaded rod 2 through a tool, facilitates the assembly of the threaded rod 2 and the mounting rod 1, and facilitates adjusting the length of the steering rod by rotating the threaded rod 2.

[0029] The working principle of the utility model is as follows: first, the ball head assembly 3 is installed on the mounting rod 1, and then the locking nut 6 is installed on the thread 21 of the threaded rod 2, and the threaded rod 2 is rotated by applying force on the spline section 23 by hand or other tools. After the length of the threaded rod 2 and the mounting rod 1 is appropriate, a bolt is inserted into the guide hole 521 of the fixing seat 5, and a nut matching the bolt is inserted into the blade 2 53, and the nut is rotated to make the blade 1 52 and the blade 2 53 fit together, and finally the locking nut 6 is rotated to make the locking nut 6 close to the mounting rod 1 to complete the assembly.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0031] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
