Description

Technical Field

[0001] This utility model belongs to the field of vehicle frame assembly technology, and in particular relates to a high-rigidity wide-body mining vehicle riveted frame applied to front and rear hydropneumatic suspension. Background Technology

[0002] In mining transport vehicles, the chassis is a key component that bears the main structure and suspension system of the vehicle. Wide-body mining trucks typically operate under harsh conditions, bearing significant dynamic and impact loads. Currently, most mining truck chassis are welded. While welding generally involves splicing and welding sheet metal, resulting in a strong and rigid structure, it is prone to stress concentration under long-term high-load conditions, leading to weld cracking and affecting the chassis's lifespan. Furthermore, once a rigid structure is damaged, it requires complete replacement, which is difficult to implement and incurs high maintenance costs. Utility Model Content

[0003] The purpose of this utility model is to provide a high-rigidity wide-body mining truck riveted frame for use with front and rear hydropneumatic suspension, so as to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A high-rigidity wide-body mining truck riveted frame for front and rear hydropneumatic suspension includes: longitudinal beams and crossbeam assemblies; the longitudinal beams include a symmetrically arranged left longitudinal beam and a right longitudinal beam, and the crossbeam assembly is riveted to the left longitudinal beam and the right longitudinal beam;

[0006] The crossbeam assembly includes, from front to back, a front crossbeam, an auxiliary crossbeam, multiple connecting crossbeams, multiple push beams, and a tail beam; wherein, the auxiliary crossbeam is arranged around the outside of the left longitudinal beam and the right longitudinal beam, and the front crossbeam, the connecting crossbeams, the push beams, and the tail beam are arranged between the left longitudinal beam and the right longitudinal beam;

[0007] A front suspension system is installed on the longitudinal beam located between the front crossbeam and the auxiliary crossbeam. A powertrain is installed on the front side of the longitudinal beam connected to the auxiliary crossbeam. A lifting cylinder bracket assembly is installed on the longitudinal beam connected to one of the connecting crossbeams. A rear suspension system is installed on the longitudinal beam connected to one of the push beams.

[0008] As a further improvement of this utility model, both the front suspension system and the rear suspension system adopt gas springs and are connected to the longitudinal beam by bolts.

[0009] As a further improvement of this utility model, the front crossbeam includes two symmetrically arranged connecting plates and a cross plate located between the two connecting plates; the two connecting plates are respectively connected to the left longitudinal beam and the right longitudinal beam.

[0010] As a further improvement of the utility model, the auxiliary cross beam includes an upper ring beam, a lower ring beam, and a support beam connecting the lower end of the upper ring beam and the upper end of the lower ring beam, and the support beam is connected to the longitudinal beam.

[0011] As a further improvement of the utility model, the connecting cross beam sequentially includes a first cross beam and a second cross beam from front to back, and a lifting oil cylinder bracket assembly is installed on the longitudinal beam connected to the second cross beam.

[0012] As a further improvement of the utility model, the transverse push beam sequentially includes a first transverse push beam, a balance push beam, and a second transverse push beam from front to back, and a rear suspension system is installed on the longitudinal beam connected to the first transverse push beam.

[0013] As a further improvement of the utility model, the tail beam includes an installation beam and a flipping pipe beam; the installation beam is in the shape of an internally hollow ring, and upper and lower rib plates are respectively connected to its upper and lower parts, and the upper and lower rib plates are connected to the longitudinal beam; the flipping pipe beam passes through the inside thereof, and both ends of the flipping pipe beam pass through the longitudinal beam.

[0014] As a further improvement of the utility model, a weight reduction groove is provided on the cross beam assembly.

[0015] As a further improvement of the utility model, the longitudinal beam is in a "U" shape, and the openings of the left longitudinal beam and the right longitudinal beam face each other.

[0016] The beneficial effects of adopting the above technical solutions are as follows:

[0017] In the utility model, the longitudinal beam and the cross beam assembly are connected by riveting, which avoids the problem of welding stress concentration, improves the durability and stability of the vehicle frame. And by optimizing the layout of the cross beam, the overall stiffness and torsional resistance of the vehicle frame are improved.

[0018] Both the front suspension system and the rear suspension system of the utility model adopt oil-gas springs. Compared with the traditional front oil-gas and rear leaf spring suspension mode of the mine vehicle frame, the rear suspension system selects an oil-gas suspension instead of a leaf spring suspension, which can not only reduce costs, but also avoid faults such as breakage of the leaf spring and the center bolt of the leaf spring, and can also reduce the overall vehicle mass.

[0019] The utility model is provided with a weight reduction groove, which reduces the gravity of the vehicle frame, and does not affect the overall stiffness and strength at the same time, taking into account the requirements of lightweight and high stiffness. Brief Description of the Drawings

[0026] To better understand the purpose, structure, and function of this utility model, a clear and complete description of this utility model will be provided below in conjunction with the accompanying drawings.

[0027] like Figures 1-5 The diagram illustrates a high-rigidity, wide-body mining truck riveted frame for front and rear hydropneumatic suspension, comprising: longitudinal beams and crossbeam assemblies; the longitudinal beams include a symmetrically arranged left longitudinal beam 1 and a right longitudinal beam 2, with the crossbeam assembly riveted to the left longitudinal beam 1 and the right longitudinal beam 2. In this embodiment, the longitudinal beams are U-shaped, with the openings of the left longitudinal beam 1 and the right longitudinal beam 2 facing each other, and the thickness of the longitudinal beams is 12mm. The longitudinal beams and crossbeam assemblies are connected by riveting, avoiding welding stress concentration problems and improving the durability and stability of the frame.

[0028] In this embodiment, the non-critical stress areas of the crossbeam assembly and longitudinal beams are provided with weight reduction grooves 15, which reduces the weight of the frame without affecting the overall rigidity and strength, thus balancing the requirements of lightweight and high rigidity.

[0029] The crossbeam assembly includes, from front to back, a front crossbeam 3, an auxiliary crossbeam 4, multiple connecting crossbeams, multiple push beams, and a tail beam 5; wherein, the auxiliary crossbeam 4 is arranged around the outside of the left longitudinal beam 1 and the right longitudinal beam 2, and the front crossbeam 3, the connecting crossbeams, the push beams, and the tail beam 5 are arranged between the left longitudinal beam 1 and the right longitudinal beam 2.

[0030] like Figure 3As shown, the front crossbeam 3 includes two symmetrically arranged connecting plates 3-1 and a transverse plate 3-2 located between the two connecting plates 3-1; the two connecting plates 3-1 are respectively connected to the left longitudinal beam 1 and the right longitudinal beam 2, and both the transverse plate 3-2 and the connecting plates 3-1 are provided with weight-reducing grooves 15. The structure of the front crossbeam 3 ensures the strength and rigidity requirements at this location to meet the needs of mounting the cab brackets on both sides of the vehicle and mounting the tow hook and front protective device on the lower side.

[0031] The front suspension system 6 is mounted on the longitudinal beam located between the front crossbeam 3 and the auxiliary crossbeam 4. For example... Figure 4 As shown, the auxiliary crossbeam 4 includes an upper ring beam 4-1, a lower ring beam 4-2, and a support beam 4-3 connected to the lower end of the upper ring beam 4-1 and the upper end of the lower ring beam 4-2. The support beam 4-3 is connected to the longitudinal beam, and the power assembly 7 is installed on the front side of the longitudinal beam connected to the auxiliary crossbeam 4. For ease of assembly, the upper ring beam 4-1, the lower ring beam 4-2, and the support beam 4-3 are all bolted together, facilitating disassembly, initial installation, and subsequent maintenance.

[0032] A lifting cylinder bracket assembly 8 is installed on the longitudinal beam connected to one of the connecting crossbeams. Specifically, the connecting crossbeams include a crossbeam 10 and two crossbeams 11 from front to back, and the lifting cylinder bracket assembly 8 is installed on the longitudinal beam connected to the two crossbeams 11.

[0033] A rear suspension system 9 is installed on the longitudinal beam connected to one of the transverse push beams. Specifically, the transverse push beams include, from front to back, a first transverse push beam 12, a balance push beam 13, and a second transverse push beam 14. The rear suspension system 9 is installed on the longitudinal beam connected to the first transverse push beam 12.

[0034] In addition, during vehicle installation, a hydraulic oil tank and battery are installed on the left side of a crossbeam 10, and an oil tank is installed on the right side; rear spring brackets are installed at the positions of crossbeam 12 and crossbeam 24; each connecting crossbeam and crossbeam is arranged at the load-bearing position of the frame, which can increase the local rigidity of the frame, resist torsional deformation, and ensure the stability of the connection between the suspension system and the frame.

[0035] In this embodiment, both the front and rear suspension systems use air springs and are connected to the longitudinal beams by bolts. Compared with the traditional mining truck frame's air spring front and leaf spring rear suspension, the use of air spring suspension instead of leaf spring suspension in the rear suspension system can reduce costs, avoid failures such as leaf spring and leaf spring center bolt breakage, and also reduce the overall vehicle weight.

[0036] like Figure 5As shown, the tail beam 5 includes a mounting beam 5-1 and a tilting tube beam 5-2. The mounting beam 5-1 is an annular structure with a hollow interior and a weight-reducing groove 15. An upper stiffening plate 5-3 and a lower stiffening plate 5-4 are connected to its upper and lower parts, respectively. The upper stiffening plate 5-3 and the lower stiffening plate 5-4 are connected to the longitudinal beam. The tilting tube beam 5-2 passes through the mounting beam, with both ends of the tilting tube beam 5-2 passing through the longitudinal beam. The tilting tube beam 5-2 passes through the longitudinal beam and is welded to the bushing. The bushing is directly connected to the tilting seat of the upper system via a tilting shaft.
