Description

Technical Field

[0001] The present application relates to the field of balanced suspension equipment structure, and in particular to an anti-loosening device for a balanced suspension thrust rod. Background Art

[0002] At present, in order to improve transportation efficiency and reduce logistics costs, heavy trucks have achieved rapid development in China. In order to obtain a larger load capacity, while not subjecting the rear axle to excessive load and reducing the ground pressure of the rear wheels, current heavy trucks are all multi-axle. When a multi-axle heavy truck is driving on an uneven road, the wheels may be suspended and the vertical loads of each wheel may be uneven. In order to solve this problem, a balanced suspension structure is usually set on the multi-axle vehicle to avoid the phenomenon of suspended wheels and uneven vertical loads on the two axles.

[0003] The balance suspension of heavy trucks includes a thrust rod, which plays a role in transmitting traction, braking force and its corresponding reaction torque on the one hand, and realizes the positioning of the frame and the axle on the other hand, ensuring the safety and stability of the vehicle. It is a key structure on the balance suspension. At present, the thrust rod is generally fastened with a thrust rod pin plus a bolt structure. However, the bolt structure will loosen due to external forces after a period of time, so it must be re-tightened. Otherwise, once the bolt connection fails, it will cause damage to the parts at the least, and may cause driving hazards at the worst. Therefore, it must be taken seriously.

[0004] In the related art, manual inspection and tightening are generally performed at intervals, which is time-consuming and laborious. In addition, since the ball head of the thrust rod is a wearing part, it needs to be frequently disassembled and repaired. The current bolt connection structure generally requires two people to disassemble and install together, which increases the difficulty of maintenance. Frequent disassembly and installation of the bolt structure will also cause obvious wear and tear, greatly shortening its service life. Summary of the invention

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] The embodiment of the present application provides an anti-loosening device for a balanced suspension thrust rod, which can solve the problem that the anti-loosening effect of the bolt connection structure in the related art is poor and the thrust rod is difficult to install due to its own structure.

[0030] Figure 1 This is the overall structural diagram of the anti-loosening device when in use. Figure 2 It is a structural schematic diagram of the first anti-loosening component. The anti-loosening device mainly includes a first anti-loosening component 1 and two groups of second anti-loosening components. The first anti-loosening component 1 is arranged at one end of the balance suspension 3. The first anti-loosening component 1 includes a first connecting portion 10 and second connecting portions 11 respectively arranged on both sides of the first connecting portion 10. The first connecting portion 10 is used to be connected with the thrust rod 4, and at least one first fastener 12 is arranged on the second connecting portion 11. The two groups of second anti-loosening components are respectively used to sequentially penetrate one side of the balance suspension 3 and the corresponding second connecting portion 11, so as to connect and fix the second connecting portion 11 with the balance suspension 3, thereby realizing the connection and fixation between the thrust rod 4 and the balance suspension 3. At least one second fastener 13 detachably connected to the first fastener 12 is arranged on one end of the second anti-loosening component close to the second connecting portion 11. The first fastener 12 and the second fastener 13 are used together to limit the relative movement of the second anti-loosening component and the second connecting portion 11 after being fixed, so as to achieve the purpose of anti-loosening.

[0031] Furthermore, the side surface of the first connecting portion 10 is approximately cylindrical. We know that the end of the thrust rod 4 is generally annular, so the surface shape of the first connecting portion 10 is consistent with the inner surface shape of the end of the thrust rod 4. The second connecting portion 11 is symmetrically arranged on both sides of the first connecting portion 10. The second connecting portion 11 is square and has a first fixing hole 14 thereon.

[0032] Furthermore, Figure 3 This is a schematic diagram of the structure of the anti-loosening nut. Figure 4 It is a vertical cross-sectional view of the anti-loosening nut. The second anti-loosening assembly specifically includes a fastening screw 20 and a anti-loosening nut 21. The fastening screw 20 is used to be arranged on one side of the balancing suspension 3, and is used to sequentially penetrate the corresponding side of the balancing suspension 3 and the corresponding second connecting portion 11. The anti-loosening nut 21 is used to be sleeved on one end of the fastening screw 20 close to the second connecting portion 11, so as to assist the fastening screw 20 in connecting and fixing the corresponding second connecting portion 11 with the balancing suspension 3, thereby fixing the thrust rod 4 with the balancing suspension 3. Among them, the anti-loosening nut 21 is also provided with a second fastener 13. When connected and fixed, the second fastener 13 is mainly used to connect with the first fastener 12 to limit the relative movement of the second anti-loosening assembly and the second connecting portion 11 after being fixed.

[0033] Furthermore, a third hexagonal fixing hole is provided on the side of the anti-loosening nut 21 close to the second connecting portion 11, and a fourth circular fixing hole is provided on the side of the anti-loosening nut 21 away from the second connecting portion 11, and a fastening nut matching the end of the fastening screw 20 close to the second connecting portion 11 is provided in the third fixing hole, and the diagonal of the third fixing hole is larger than the diameter of the fourth fixing hole. Since the diagonal of the third fixing hole is larger than the diameter of the fourth fixing hole, it is equivalent to forming a hexagonal groove on the side of the anti-loosening nut 21 close to the second connecting portion 11, and the fastening nut is provided in the groove, and the side of the fourth fixing hole connected to the third fixing hole is used as abutment surface to abut on the fastening nut, which further ensures the anti-loosening effect and also makes it unnecessary for other personnel to align the fastening nut when assembling the thrust rod 4.

[0034] Furthermore, the second fastener 13 includes a fastening strip, one side of which is provided on the anti-loosening nut 21, and the one side at least partially extends out of the anti-loosening nut 21 to form an extension section, and a second fixing hole 22 is provided on the extension section, and the second fixing hole 22 is used to be detachably mounted on the first fastener 12, so as to limit the relative movement of the second anti-loosening component and the second connecting portion 11 after being fixed. The first fastener 12 is a convex block with a certain height, and the upper half of the block of the first fastener 12 on one side away from the second fastener 13 extends forward to form a stopper. Therefore, when the second anti-loosening component is fixed to the second connecting portion 11, the second fixing hole 22 on the extension section of the fastening strip is mounted on the first fastener 12, and the stopper of the first fastener 12 can prevent it from accidentally falling out of the second fixing hole 22, thereby ensuring the stability of the connection.

[0035] Furthermore, the fastening screw 20 and the locking nut 21 are both made of plastic, and the second fastener 13 is made of rubber, which has a certain elasticity, so that it is convenient to remove or sleeve it from the first fastener 12. From the perspective of structural strength, the first connecting portion 10, the second connecting portion 11 and the first fastener 12 are all made of stainless steel. In addition, the first fastener 12 is integrally formed with the second connecting portion 11, and the second fastener 13 is integrally formed with the locking nut 21.

[0036] Furthermore, from the perspective of structural design, each second connecting portion 11 is provided with two first fasteners 12, and the two first fasteners 12 are symmetrically arranged at the top and bottom of the second connecting portion 11. Correspondingly, each anti-loosening nut 21 includes two second fasteners 13, and the two second fasteners 13 are symmetrically arranged at the top and bottom of the anti-loosening nut 21. The top and the bottom are fixed at the same time, which can ensure its anti-loosening effect.

[0037] The principle of this anti-loosening device is:

[0038] When in use, first assemble the thrust rod 4 with the first connecting part 10, that is, one end of the thrust rod 4 is sleeved on the first connecting part 10, and then the fastening nut is placed in the hexagonal third fixing hole in the anti-loosening nut 21, and then the second fastener 13 on each anti-loosening nut 21 is connected to the first fastener 12, so that the second fixing hole 22 on the fastening strip is sleeved on the first fastener 12. After the installation is completed, the fastening screw 20 is successively passed through the corresponding side of the balancing suspension 3 and the corresponding second connecting part 11 and then contacted with the fastening nut, and finally the fastening screw 20 is rotated to pass through the fastening nut and the fourth fixing hole, and the final assembly is completed.

[0039] Compared with the traditional anti-loosening device, the anti-loosening device has a good anti-loosening effect, can effectively limit the rotation of the fastening nut due to external force in the later stage, and can effectively prevent loosening, and the sleeve setting of the anti-loosening nut 21 and the fastening nut further ensures the anti-loosening effect. Secondly, it ensures that only one person is required to complete the assembly of the thrust rod 4, and no extra people are required to hold and fix the anti-loosening nut 21 and the fastening nut. If wear occurs after multiple uses, only the fastening nut needs to be replaced, and the anti-loosening nut 21 can be reused multiple times. In general, the device has a good anti-loosening effect, a simple overall structure, light weight, low cost, and great practical value.
