Description

Technical Field

[0001] This invention generally relates to the field of transportation technology, and more specifically, to a dump truck frame and a dump truck. Background Technology

[0002] Existing mining dump trucks include a steering tie rod and a steering cylinder. The steering tie rod and steering cylinder work together to transmit steering force and stabilize the axle, ensuring the normal steering of the mining dump truck. Currently, the steering tie rod is mostly placed at the front or rear of the gantry beam or gantry frame. This method has the following drawbacks:

[0003] 1. Mining dump trucks are widely used in open-pit mines, where the working conditions are relatively worse than those of road vehicles. The steering tie rods are exposed on the outside of the frame or near the axle, and the steering tie rods have poor protection. They are directly exposed to the collision and erosion of gravel, mud, sand and sharp obstacles in the mining area, and are prone to deformation, wear or breakage. Especially on bumpy roads or when turning under heavy load, they are subjected to greater impact loads and have a higher failure rate.

[0004] 2. If the steering tie rod is located in front of the axle housing, it may interfere with components such as the engine and drive shaft, affecting the flexibility of the overall vehicle layout. If the steering tie rod is located behind the axle housing, it may cause motion interference with the suspension components due to axle movement, posing a risk of spatial interference.

[0005] 3. Although externally mounted steering tie rods facilitate visual inspection, they are exposed to harsh environments for extended periods. Dust, mud, and other contaminants can easily accumulate at the ball joints, hinge points, and other connecting parts, leading to lubrication failure, corrosion, and other issues. This necessitates frequent cleaning of contaminants, increasing maintenance costs. Summary of the Invention

[0006] The present invention provides a dump truck frame and a dump truck that can improve protection performance and space utilization.

[0007] According to a first aspect of the present invention, a dump truck frame is provided, including a frame body assembly, the frame body assembly comprising:

[0008] A middle beam extends along a first direction, and a first channel is provided inside the middle beam, which extends along a second direction.

[0009] Multiple side wings are provided on both sides of the middle beam along the second direction. A second channel is provided in the side wings. The second channels corresponding to two side wings arranged opposite each other along the second direction are connected through the first channel to form a connecting channel for the steering tie rod to pass through.

[0010] Wherein, the first direction and the second direction are perpendicular to each other.

[0015] In some embodiments, the flanks include:

[0016] The housing has a through hole on the side of the housing along the second direction and away from the first channel;

[0017] A stiffening plate is disposed inside the box. The stiffening plate has a connecting part on one side facing the first channel along the first direction. The through hole and the connecting part are connected to form the second channel.

[0018] In some embodiments, the flanks further include:

[0019] An adapter is disposed inside the housing and rotatably connected to the steering tie rod;

[0020] The box body has an opening, and the cover plate is placed over the opening and detachably connected to the box body.

[0021] In some embodiments, the intermediate beam is provided with a steering cylinder support on at least one side along the second direction.

[0022] In some embodiments, the bottom of the intermediate beam along a third direction is provided with a first lifting seat and a second lifting seat, the first lifting seat being connected to the second lifting seat.

[0023] In some implementations, it also includes:

[0024] A frame end assembly is disposed at the end of the frame main body assembly along the first direction;

[0025] A connecting beam extends downward along a third direction from one end of the intermediate beam toward the frame end assembly in the first direction and toward the frame end assembly, and is connected to the frame end assembly;

[0026] Wherein, the third direction is perpendicular to the first direction and the second direction.

[0027] In some embodiments, the frame end assembly includes:

[0028] The first crossbeam and the second crossbeam are arranged in parallel and spaced apart along the first direction, with the first crossbeam located on the side of the second crossbeam along the first direction and facing the main frame assembly.

[0029] The third crossbeam and the first connecting rod are located below the first crossbeam along a third direction, and the third crossbeam is connected to the first crossbeam through the first connecting rod.

[0030] The bumper and the second link are located below the second crossbeam along the third direction and on the side of the third crossbeam along the first direction away from the main frame assembly. The bumper is connected to the second crossbeam via the second link.

[0031] The connecting beam connects the intermediate beam, the first crossbeam, and the bumper.

[0032] According to a second aspect of the present invention, an embodiment of the present invention also provides a dump truck, including the dump truck frame and the driving unit described above, wherein the driving unit is disposed on the dump truck frame.

[0033] In some embodiments, the driving unit includes a front axle driving unit, a middle axle driving unit, and a rear axle driving unit, wherein the front axle driving unit, the middle axle driving unit, and the rear axle driving unit are arranged along the first direction, and the middle axle driving unit is located between the front axle driving unit and the rear axle driving unit;

[0034] The dump truck also includes multiple half-shafts, and multiple side wings of the dump truck frame are provided with multiple through holes, and the multiple half-shafts are respectively inserted through the multiple through holes;

[0035] Each of the front axle driving unit, the middle axle driving unit, and the rear axle driving unit is connected to two side wings arranged opposite each other along the second direction via two half-shafts.

[0036] One embodiment of the present invention has the following advantages or beneficial effects:

[0037] The dump truck frame and dump truck provided by the present invention, when the steering tie rod is built into the dump truck frame, the connection point of the steering tie rod and other components can be closer to the main load-bearing structure of the dump truck frame. When transmitting steering force, it can reduce the deformation caused by the lever effect, enhance structural stability, improve the overall rigidity and response accuracy of the steering system, and reduce the lag phenomenon during the steering process.

[0038] By setting a first channel extending in the second direction within the middle beam and a second channel within the side wings on both sides of the middle beam, the second channels of the two opposite side wings are connected with the first channel to form a connecting channel. This allows the steering tie rod to be internally penetrated, and the main frame structure provides physical protection for the steering tie rod, avoiding direct impact and wear from mining debris, mud splashes, or ground obstacles. This reduces the risk of deformation and breakage of the steering tie rod and extends its service life.

[0039] By integrating the steering tie rod into the dump truck frame, external environmental corrosion and damage to the tie rod are reduced, lowering the failure rate and consequently reducing the frequency of maintenance and replacement. Furthermore, the tie rod is housed within a connecting channel, keeping it away from areas prone to dust and mud accumulation, thus reducing contamination of lubrication points and minimizing routine maintenance workload.

[0040] Because the vehicle steering system needs to withstand huge impact forces and torques under bumpy and heavy working conditions such as in mining areas, the steering tie rod is built into the dump truck frame. The steering tie rod can distribute some of the stress with the support of the dump truck frame, avoid a single component bearing too large a load, improve the reliability of the steering system, improve the adaptability to harsh working conditions, and ensure the normal operation of the dump truck under extreme conditions.

[0041] Connecting the first and second channels to form a through channel running along the second direction can prevent spatial interference between the steering tie rod and components such as the suspension, axle, or transmission system under the dump truck frame, thereby improving space utilization. It is especially suitable for dump truck structures with multi-axle steering, providing greater flexibility for the layout of vehicle components. Attached Figure Description

[0063] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0064] This embodiment provides a dump truck frame, such as Figures 1-2As shown, the dump truck frame includes a frame main assembly 100, which includes a central beam 1 and multiple side wings 2. The central beam 1 extends along a first direction, and the multiple side wings 2 are disposed on both sides of the central beam 1 along a second direction.

[0065] For example, the intermediate beam 1 is similar to a long strip structure. The intermediate beam 1 has at least one reference plane. The first direction and the second direction are two directions that are perpendicular to each other on the reference plane. The third direction is perpendicular to the reference plane. The first direction, the second direction and the third direction are perpendicular to each other. The first direction is identified by D1, the second direction is identified by D2 and the third direction is identified by D3.

[0066] For example, there are six side wings 2. The six side wings 2 can be specifically divided into front axle side wings, middle axle side wings and rear axle side wings. The middle axle side wings are located between the front axle side wings and the rear axle side wings. The front axle side wings have two side wings that are arranged opposite each other along the second direction. These two side wings 2 can be specifically referred to as the left and right front axle side wings. The middle axle side wings have two side wings 2 that are arranged opposite each other along the second direction. These two side wings 2 can be specifically referred to as the left and right middle axle side wings. The rear axle side wings have two side wings 2 that are arranged opposite each other along the second direction. These two side wings 2 can be specifically referred to as the left and right rear axle side wings.

[0067] For example, the intermediate beam 1 and the side wing 2 can be fixed by welding, which is simple and has a good fixing effect.

[0068] By setting the middle beam 1 to extend along the first direction to adapt to the longitudinal spatial arrangement of the dump truck frame, and multiple side wings 2 symmetrically distributed on both sides of the middle beam 1 along the second direction to adapt to the lateral spatial arrangement of the dump truck frame, the load-bearing and space requirements of the dump truck frame are met, the overall stress balance of the dump truck frame can be guaranteed, and the structural stability under heavy load conditions can be improved.

[0069] like Figures 3-6 As shown, a first channel 10 is provided in the middle beam 1, and the first channel 10 extends along the second direction; a second channel 20 is provided in the side wing 2, and the second channels 20 corresponding to the two side wings 2 arranged opposite to each other along the second direction are connected through the first channel 10 to form a connecting channel for the steering tie rod 700 to pass through.

[0070] Since the dump truck frame is the core load-bearing component of the vehicle, it has high rigidity. By incorporating the steering tie rod 700 inside the dump truck frame, the connection point of the steering tie rod 700 and other components can be closer to the main load-bearing structure of the dump truck frame. When transmitting steering force, it can reduce deformation caused by leverage effect, enhance structural stability, improve the overall rigidity and response accuracy of the steering system, and reduce lag during steering.

[0071] By setting a first channel 10 extending in the second direction in the middle beam 1, and setting a second channel 20 in the side wings 2 located on both sides of the middle beam 1, the second channel 20 of the two opposite side wings 2 are connected with the first channel 10 to form a connecting channel, and the steering tie rod 700 passes through the connecting channel. The main structure of the frame provides physical protection for the steering tie rod 700, avoiding direct impact and wear of the steering tie rod 700 by mining gravel, mud and sand splashes or ground obstacles, reducing the risk of deformation and breakage of the steering tie rod 700, and extending its service life.

[0072] By integrating the steering tie rod 700 into the dump truck frame, external environmental corrosion and damage to the steering tie rod 700 are reduced, lowering the failure rate and consequently reducing the frequency of maintenance and replacement. Simultaneously, the steering tie rod 700 is housed within a connecting channel, keeping it away from areas prone to dust and mud accumulation, thus reducing contamination of lubrication points and minimizing daily maintenance workload.

[0073] Because the steering system needs to withstand huge impact forces and torques under bumpy and heavy working conditions such as in mining areas, the steering tie rod 700 is built into the dump truck frame. The steering tie rod 700 can distribute some of the stress with the support of the dump truck frame, avoid a single component bearing excessive load, improve the reliability of the steering system, improve the adaptability to harsh working conditions, and ensure the normal operation of the dump truck under extreme conditions.

[0074] By connecting the first channel 10 and the second channel 20 to form a connecting channel running through the second direction, spatial interference between the steering tie rod 700 and components such as the suspension, axle, or transmission system under the dump truck frame can be avoided, thereby improving space utilization. It is especially suitable for dump truck structures with multi-axle steering, providing greater flexibility for the layout of vehicle components.

[0075] In one embodiment, such as Figures 3-6 As shown, the intermediate beam 1 includes a connecting plate 11 and two side plates 12, which are disposed on both sides of the connecting plate 11 along the second direction. A reinforcing part 13 passes through the side plates 12 and is disposed between the two side plates 12, and a first channel 10 is disposed within the reinforcing part 13.

[0076] Specifically, the reinforcing section 13 significantly improves the overall rigidity and torsional resistance of the intermediate beam 1, preventing deformation of the intermediate beam 1 under heavy loads and bumpy conditions in the mining area. By incorporating the first channel 10 within the reinforcing section 13, the reinforcing section 13 strengthens the structure surrounding the first channel 10, preventing cracking at the edges of the first channel 10 due to stress when the steering tie rod 700 passes through. Simultaneously, the design of the reinforcing section 13 penetrating the side plate 12 allows for a more even distribution of the steering force of the steering tie rod 700 across the entire intermediate beam 1, reducing localized stress concentration and improving the response accuracy of the steering system.

[0077] In one embodiment, the side wing 2 includes a housing 21 and stiffening plates 22, with the stiffening plates 22 disposed within the housing 21. The stiffening plates 22 can effectively enhance the bending and deformation resistance of the housing 21, preventing structural failure of the side wing 2 when bearing the load of the driving unit or bearing steering force, and improving the adaptability of the dump truck in harsh working conditions in mining areas.

[0078] The box body 21 has a through hole 211 on the side away from the first channel 10 along the second direction; the stiffening plate 22 has a connecting part 221 on the side facing the first channel 10 along the first direction, and the through hole 211 and the connecting part 221 are connected to form the second channel 20.

[0079] For example, the connecting portion 221 may be provided on the stiffener 22 with a circular hole; the connecting portion 221 may also be provided on the groove on the stiffener 22, in which case the cross-section of the stiffener 22 is similar to a C-shaped structure.

[0080] The second channel 20 is formed by the connecting part 221 on the stiffening plate 22 and the through hole 211 of the housing 21, ensuring precise connection between the second channel 20 and the first channel 10. This ensures that the steering tie rod 700 can pass through smoothly, providing guidance and facilitating the installation and maintenance of the steering tie rod 700. Simultaneously, the stiffening plate 22 can locally reinforce the surrounding area of ​​the second channel 20, increasing its load-bearing capacity and preventing localized wear or cracking of the housing 21 due to the swinging of the steering tie rod 700.

[0081] Because the steering tie rod 700 is relatively long, it passes through two side wings 2 that are arranged opposite to each other along the second direction. Specifically, after the steering tie rod 700 passes through the second channel 20 formed by the through hole 211 and the connecting part 221 in one of the side wings 2, the steering tie rod 700 passes through the first through hole 25 and passes through the second channel 20 of the other side wing 2 that is arranged opposite to each other, so that the steering tie rod 700 is built into the vehicle frame.

[0082] In one embodiment, such as Figure 4 As shown, the side wing 2 also includes an adapter 23, which is disposed inside the housing 21 and rotatably connected to the steering tie rod 700. This configuration can accommodate the swinging requirements of the steering tie rod 700 during steering, reduce friction between the steering tie rod 700 and the side wing 2, and also ensure the smoothness of the steering action of the steering tie rod 700, thereby improving the reliability of the steering system.

[0083] Among them, such as Figure 4 As shown, the side wing 2 also includes a cover plate 24, and the box body 21 is provided with a through hole 25. One end of the through hole 25 forms an opening, and the cover plate 24 covers the opening and is detachably connected to the box body 21.

[0084] For example, the cover plate 24 and the housing 21 can be fixed together by bolts, which facilitates the installation and disassembly of the housing 21 and the cover plate 24.

[0085] For example, a clearance hole may be provided on the cover plate 24 for the passage of lines and pipes.

[0086] The cover plate 24 seals the opening of the housing 21, providing a relatively enclosed space for the steering tie rod 700. This prevents mining dust and mud from entering the housing 21 and contaminating the steering tie rod 700, reducing contamination of lubrication points. Simultaneously, the cover plate 24 is detachably connected to the housing 21, facilitating future inspection, maintenance, or replacement of the steering tie rod 700 without disassembling the entire side wing 2, thus reducing maintenance costs and workload.

[0087] In one embodiment, such as Figure 7 As shown, at least one side of the intermediate beam 1 along the second direction is provided with a steering cylinder support 3, which is used to install the steering cylinder.

[0088] Since the intermediate beam 1 is the core load-bearing structure of the dump truck frame, the steering cylinder support 3 is installed on the side of the intermediate beam 1. The high rigidity of the intermediate beam 1 can provide stable support for the steering cylinder support 3, avoiding the situation where the steering cylinder support 3 is deformed or falls off due to excessive load when the steering cylinder is working, thus improving the safety of the steering system.

[0089] By setting the steering cylinder support 3 to the side of the intermediate beam 1 along the second direction, the distance between the steering cylinder and the steering tie rod 700 can be made closer, and the steering force output by the steering cylinder can be transmitted to the steering tie rod 700 more directly, reducing the loss and lag in the force transmission process and improving the steering response accuracy.

[0090] In one embodiment, such as Figure 7 As shown, the middle beam 1 is provided with a first lifting seat 4 and a second lifting seat 5 at the bottom along the third direction, and the first lifting seat 4 is connected to the second lifting seat 5.

[0091] Compared to an integrated lifting platform, the separate structure of the first lifting platform 4 and the second lifting platform 5 significantly reduces casting or machining difficulties, minimizes the forming risks of large castings, and lowers production costs. Furthermore, the connection between the first lifting platform 4 and the second lifting platform 5 maintains overall load-bearing strength, stably withstanding the enormous lifting force exerted when the dump truck lifts its cargo box.

[0092] In one embodiment, the side wing 2 is also provided with an interface (not shown in the figure), which is used to connect with the independent hydraulic suspension and has strong functionality.

[0093] In one embodiment, such as Figure 1 and Figure 8As shown, the dump truck frame also includes a frame end assembly 200 and a connecting beam 300. The frame end assembly 200 is disposed at the end of the frame main assembly 100 along a first direction. The connecting beam 300 extends downward along a third direction from the intermediate beam 1 along the first direction and toward the frame end assembly 200, and is connected to the frame end assembly 200.

[0094] This downward extension method avoids interference between the connecting beam 300 and components such as the lifting seat and driving unit below the intermediate beam 1, which is conducive to the full utilization of space and can reserve space for the arrangement of internal equipment such as batteries, motors, and air conditioning outdoor units.

[0095] Meanwhile, the connecting beam 300 extends from the middle beam 1 along the first direction toward the end component 200 of the frame, and extends downward along the third direction to connect with the end component. This can strengthen the connection strength between the main frame component 100 and the end component 200 of the frame, forming a three-dimensional support, improving the overall torsional and impact resistance of the dump truck frame, and reducing the risk of the end component 200 of the frame shaking under bumpy working conditions in the mining area.

[0096] Specifically, such as Figure 8 As shown, the end frame assembly 200 includes a first crossbeam 201, a second crossbeam 202, a third crossbeam 203, a first connecting rod 204, a bumper 205, and a second connecting rod 206. The first crossbeam 201 and the second crossbeam 202 are arranged parallel to each other along a first direction and are spaced apart. The first crossbeam 201 is located on the side of the second crossbeam 202 along the first direction and facing the main frame assembly 100. The third crossbeam 203 and the first connecting rod 204 are located below the first crossbeam 201 along a third direction, and the third crossbeam 203 is connected to the first crossbeam 201 through the first connecting rod 204. The bumper 205 and the second connecting rod 206 are located below the second crossbeam 202 along a third direction and on the side of the third crossbeam 203 along the first direction and away from the main frame assembly 100. The bumper 205 is connected to the second crossbeam 202 through the second connecting rod 206.

[0097] Specifically, the end frame assembly 200 forms an upper frame by arranging the first crossbeam 201 and the second crossbeam 202 along the first direction. The third crossbeam 203 and the first connecting rod 204 connect the first crossbeam 201 to form a lower support. The bumper 205 connects the second crossbeam 202 through the second connecting rod 206 to form front protection. The combination structure of the multi-layer crossbeams and connecting rods can significantly improve the rigidity and impact resistance of the end frame assembly 200, and avoid the deformation of the end frame caused by collisions with obstacles in front of the mining area.

[0098] Specifically, the bumper 205 is directly connected to the lower part of the second crossbeam 202 and located outside the third crossbeam 203, which can resist external collisions and directly protect the internal equipment located in the end frame assembly 200.

[0099] The connecting beam 300 connects the intermediate beam 1, the first crossbeam 201, and the bumper 205. This arrangement allows the impact force or driving bump force to be distributed to the main frame assembly 100 and the end frame assembly 200 through the connecting beam 300, avoiding local stress concentration and further improving the damage resistance of the end frame assembly 200.

[0100] This embodiment also provides a dump truck, such as Figure 9 As shown, the dump truck includes the aforementioned dump truck frame, dump truck frame, and driving unit, with the driving unit disposed on the dump truck frame.

[0101] The dump truck also provided in this embodiment has a steering tie rod 700 built into the dump truck frame. The steering tie rod 700 can distribute some of the stress with the support of the dump truck frame, avoid a single component bearing excessive load, improve the reliability of the steering system, improve the adaptability to harsh working conditions, and ensure the normal operation of the dump truck under extreme conditions.

[0102] By connecting the first channel 10 and the second channel 20 to form a connecting channel running through the second direction, spatial interference between the steering tie rod 700 and components such as the suspension, axle, or transmission system under the dump truck frame can be avoided, thereby improving space utilization. It is especially suitable for dump truck structures with multi-axle steering, providing greater flexibility for the layout of vehicle components.

[0103] Specifically, the driving unit includes a front axle driving unit 400, a middle axle driving unit 500, and a rear axle driving unit 600. The front axle driving unit 400, the middle axle driving unit 500, and the rear axle driving unit 600 are arranged along a first direction, with the middle axle driving unit 500 located between the front axle driving unit 400 and the rear axle driving unit 600.

[0104] For example, the main frame assembly 100 has six side wings 2, which can be specifically divided into front axle side wings, middle axle side wings, and rear axle side wings. The middle axle side wings are located between the front axle side wings and the rear axle side wings. Each of the front axle side wings, middle axle side wings, and rear axle side wings has two side wings 2 arranged opposite each other along a second direction. The dump truck frame, the front axle running unit 400, the middle axle running unit 500, and the rear axle running unit 600 are respectively arranged on the front axle side wings, the middle axle side wings, and the rear axle side wings.

[0105] In one embodiment, the dump truck further includes multiple half-shafts (not shown in the figure), and multiple side wings 2 of the dump truck frame are provided with multiple through holes 25, and the multiple half-shafts are respectively inserted through the multiple through holes 25; each of the front axle travel unit 400, the middle axle travel unit 500 and the rear axle travel unit 600 is connected to two side wings 2 arranged opposite to each other along the second direction through two half-shafts.

[0106] This multi-axle arrangement can accommodate three driving units: the front axle, the middle axle, and the rear axle. Multi-axle support effectively reduces the axle load on a single axle, lowers the load-bearing pressure on individual driving units, and extends the service life of the axles and wheels. Simultaneously, one half-axle can be rotatably connected to two wheels via a connecting frame. This multi-axle arrangement increases the number of tires and allows for a smaller tire diameter under the same load, thereby lowering the overall vehicle height, lowering the center of gravity, and improving the stability of the dump truck on rough roads in mining areas, reducing the risk of rollover.

[0107] In addition, the two half-shafts correspond to one travel unit through two side wings 2 arranged opposite to each other along the second direction, which can evenly distribute the load of the travel unit to the two side wings 2, avoid excessive force on one side wing 2 and thus ensure the stability of the power transmission of the travel unit.
