[0021] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] This embodiment provides a left and right tie rod arm, which reduces resource waste when the tie rod arm is replaced and maintained in the later stage of use. Specifically, Figure 1-4 As shown, it includes a tie rod arm body 1, a plurality of protective members 2 and a nut 3. The surface of the tie rod arm body 1 is penetrated with two connection ports 11 and a connection port 2 12. The connection port 11 is opened in the horizontal direction, and the connection port 2 12 is opened in the longitudinal direction. The surface of the tie rod arm body 1 and the positions close to the connection port 1 11 and the connection port 2 12 are respectively provided with a concave groove 13 and a concave groove 24 along the ring. The plurality of protective members 2 are respectively arranged in the two connection ports 1 11 and the one connection port 2 12. The protective member 2 includes a hollow cylinder 21. The surface of the hollow cylinder 21 is provided with a convex plate 22, and the protruding To the connection port 11 and the recessed groove 13, a threaded path 23 is provided on the outer side of the hollow cylinder 21 and away from the convex plate 22. The nut 3 is arranged on the outer side of the hollow cylinder 21 through the threaded path 23, and the nut 3 is located on the inner side of the recessed groove 14. Therefore, when the transverse tie rod arm body 1 is connected with the connecting piece (not shown in the figure) for use, the connecting piece can directly contact the surface of the protective piece 3, effectively realizing the isolation and protection effect of the transverse tie rod arm body 1, avoiding the wear due to long-term use, and avoiding the situation where a large amount of resources are wasted by the need to replace the entire part when replacement and maintenance are required.

[0024] In order to make the state of the nut 3 more stable, Figure 1-3 As shown, in this embodiment, a rubber ring 4 is provided on the surface of the tie rod arm body 1 and near the position in the recessed groove 14, and one side of the nut 3 is in close contact with one side of the rubber ring 4, thereby effectively preventing the nut 3 from being easily loosened due to vibration generated during the driving of the vehicle.

[0025] In order to prevent one end surface of the hollow tube 21 of the protective member 2 from being easily deformed, Figure 1-3As shown, in this embodiment, the side of the hollow cylinder 21 away from the convex plate 22 is in the same plane as the side of the nut 3, and a protrusion 15 is provided on the surface of the transverse tie rod arm body 1 and close to the position in the recessed groove 14. One side of the nut 3 contacts one side of the protrusion 15, so that the nut 3 is effectively utilized to provide a certain supporting effect on the hollow cylinder 21, avoiding the deformation of the connecting piece when a certain pressure is applied to the end face of the hollow cylinder 21.

[0026] In order to facilitate the installation of the protective member 2 and the tie rod arm body 1 by the staff at the early stage, Figure 1-2 As shown, in this embodiment, the surface of the protruding plate 22 is provided with two openings 221, the surface of the transverse tie rod arm body 1 is provided with a protrusion 16 protruding into the opening 221, the surface of the protruding plate 22 is provided with two openings 222, the surface of the transverse tie rod arm body 1 is provided with a rubber block 5 protruding into the opening 222, and a gap is left between the outer side of the nut 3 and the transverse tie rod arm body 1 through the recessed groove 2 14, so as to avoid easy sliding when the protective member 2 and the transverse tie rod arm body 1 are connected, thereby affecting the installation.

[0027] like Figure 1-2 As shown, in this embodiment, the surface of the protruding plate 22 and the corners close to the opening 1 221 and the opening 2 222 are rounded, and the surface of the protruding plate 22 is provided with multiple sets of anti-slip grooves 223, which is more convenient for the staff to insert the protective member 2 into the protrusion 16 and the rubber block 5.

[0028] During the use of the above-mentioned tie rod arm, if it is worn and needs maintenance and replacement, the staff can use tools to disassemble the nut 3 and the hollow cylinder 21 through the recessed groove 14, and then push the hollow cylinder 21 outward from the connection port 11 or the connection port 2 12, and then insert the protective member 2 to be replaced into the connection port 1 11 or the connection port 2 12, and make its convex plate 22 completely protrude into the recessed groove 13, and the protrusion 16 and the rubber block 5 protrude into the opening 1 221 and the opening 2 222 respectively, and finally, the nut 3 can be used to connect with the hollow cylinder 21 until the nut 3 is in close contact with the rubber ring 4.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
