[0002] Off-highway wide-body dump trucks are heavy-duty transport vehicles designed for use off public roads and are widely used in mining, construction, and large-scale earthmoving projects. In actual operation, off-highway wide-body dump trucks often encounter harsh working conditions such as poor road surface roughness, heavy loads uphill, and sharp turns. These factors place extremely high demands on the performance of the vehicle structure and components.

[0003] In existing off-highway wide-body dump trucks, the V-shaped pushrod system is a key load-bearing component within the frame and suspension structure. It comprises a pushrod and a support, both of which are responsible for bearing the longitudinal and lateral loads generated by the vehicle during travel. However, due to the harsh conditions of off-highway vehicles, especially under heavy loads, the pushrod and support are subject to significant lateral loads. This stress concentration often causes cracking and fatigue fracture in the vertical ribs, shortening the support's service life and increasing maintenance frequency and costs, directly impacting vehicle availability.

[0024] Please refer to Figure 1 The embodiment of the present invention provides a dump truck thrust rod support, which includes a support body 1, a main mounting portion 2 arranged in the middle of the support body 1, and auxiliary mounting portions 3 arranged at both ends of the support body 1.

[0025] The support body 1 is connected to the body of the dump truck, with a first connecting hole 21 and a second connecting hole 31 respectively provided on the main mounting portion 2 and the secondary mounting portion 3. Bolts are inserted into the first connecting hole 21 and the second connecting hole 31 to mount the dump truck's thrust rod on the support body 1. The support body 1 is provided with multiple mounting holes 10 on both sides of the main mounting portion 2 and the secondary mounting portion 3, through which the support body 1 can be fixed to the body of the dump truck. A receiving groove 4 for accommodating the dump truck's thrust rod is formed between the main mounting portion 2 and the secondary mounting portion 3. The support body 1 is also provided with a connecting portion 5, the two ends of which are respectively connected to the main mounting portion 2 and the secondary mounting portion 3 to distribute the load.

[0026] When the dump truck thrust rod is subjected to a heavy load, the connecting portion 5 provides temporary support, preventing stress concentration on the main mounting portion 2 and the auxiliary mounting portion 3. Furthermore, the temporary support provided by the connecting portion 5 improves the stability of the thrust rod under heavy load conditions and reduces the risk of deformation or damage to the thrust rod.

[0027] Preferably, the front and rear end surfaces of the support body 1 are provided with a reinforcement structure, which includes a main reinforcement plate 6 and a secondary reinforcement plate 7. The two mutually perpendicular adjacent edges of the main reinforcement plate 6 respectively connect the support body 1 and the main mounting portion 2, and the two mutually perpendicular adjacent edges of the secondary reinforcement plate 7 respectively connect the support body 1 and the secondary mounting portion 3. This balances the forces at both ends of the support, enhances the support's ability to resist deformation under longitudinal and transverse loads, and thus improves its overall durability and stability.

[0028] In this embodiment, the support body 1, the main mounting portion 2, the auxiliary mounting portion 3, the connecting portion 5 and the reinforcement structure are formed as one piece. The one-piece design eliminates the need for connecting the various components through connecting welds or connectors, reducing potential connection weaknesses and thereby improving the strength and rigidity of the overall structure.

[0029] To further reduce structural damage caused by stress concentration, in this embodiment, a circular arc-shaped transition section 8 is formed on one side surface of the main reinforcement plate 6 to transition with the connection point of the main mounting portion 2. Correspondingly, a circular arc-shaped transition section 8 is formed on one side surface of the secondary reinforcement plate 7 to transition with the connection point of the secondary mounting portion 3. The radius of the transition section 8 is 15mm-20mm. Those skilled in the art can set the radius of the transition section 8 to 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, etc. according to actual conditions, and this is not a sole limitation. By adopting a smooth circular arc transition design, the stress distribution at the connection is more uniform, effectively avoiding cracking and fatigue fracture caused by stress concentration, and extending the service life of the support.

[0030] Preferably, a rounded transition structure 9 is used at the connection between the connecting portion 5 and the main mounting portion 2, and at the connection between the auxiliary mounting portion 3, and the radius of the transition structure 9 is 50 mm to 60 mm. Those skilled in the art can set the radius of the transition structure 9 to 50 mm, 51 mm, 52 mm, 53 mm, 54 mm, 55 mm, 56 mm, 57 mm, 58 mm, 59 mm, 60 mm, etc. according to actual conditions. The provision of the transition structure 9 ensures smooth connection between the various parts and avoids sharp corners that cause stress concentration.

[0031] In this embodiment, a first mounting step 22 is provided on one side surface of the main mounting portion 2 around the first connecting hole 21, and a second mounting step 32 is provided on one side surface of the auxiliary mounting portion 3 around the second connecting hole 31. After the thrust rod is installed, the first mounting step 22 and the second mounting step 32 can form an abutment against one end of the thrust rod, forming a transition support between the main and auxiliary mounting portions 3 and the thrust rod. The transition support can evenly disperse the stress at the connection and reduce the risk of cracking or fatigue damage caused by local stress concentration. In addition, the abutment effect of the first mounting step 22 and the second mounting step 32 can also improve the connection stability of the thrust rod and improve the overall load-bearing capacity of the thrust rod and the support structure, thereby enhancing the reliability and durability of the dump truck under complex working conditions.

[0032] An embodiment of the present invention also provides a dump truck, including a body, a thrust rod and the above-mentioned dump truck thrust rod support. The support body 1 of the dump truck thrust rod support is connected to the body of the dump truck by bolts through the mounting hole 10, thereby being fixed to the body of the dump truck to ensure that the support structure has high stability when the vehicle is running and reduce loosening caused by vibration or impact.

[0033] In this embodiment, one end of the thrust rod is arranged on the connecting part 5, and a mounting part is provided at the tail of the thrust rod. The mounting part is respectively abutted against the first mounting step 22 and the second mounting step 32, and is bolted to the support body 1 through the first connecting hole 21 and the second connecting hole 31 for easy maintenance.

[0034] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention are intended to be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
