Description

Technical Field

[0001] This disclosure relates to truck bodies and trucks that include truck bodies. Background Technology

[0002] Abrasion-resistant liners are known and used in chute and truck platforms to protect the base. They are typically made of natural or synthetic rubber and are used to protect against hard impacts from rocks and abrasion from materials that move and come into contact with the liner element's surface. Softer rubber materials offer good abrasion resistance, but the liner element must be relatively thick to prevent hard impacts from penetrating it. Harder rubber materials offer better protection against impacts but are more susceptible to abrasive wear. Therefore, liner elements have been developed in which different combinations of materials are incorporated in the outward-oriented surface of the element on which fragments or granular materials (such as crushed ore and broken rock) will move.

[0003] When using such liner elements to protect surfaces (such as those on a truck body) from wear, a problem arises where material can manage to seep under the liner element by traveling between its edge and the surface it abuts. This problem is particularly pronounced in truck bodies with at least partially sloping sidewalls (such as those commonly used in articulated trailer trucks). These articulated trucks can be used as off-road articulated trailer trucks, typically in mines or quarries, or as highway articulated trucks, typically in road construction and building sites. The material that seeps under the liner element is problematic because it gradually loosens the liner element from the surface it is attached to, eventually causing it to detach. Furthermore, the truck carries unnecessary weight, leading to higher fuel consumption and costs exceeding what is necessary.

[0004] To address these issues, lining elements are typically equipped with integrated steel end protection, which is welded to the truck body. This results in high production costs and long installation times. Utility Model Content

[0005] One object of this invention is to mitigate, alleviate, or eliminate one or more of the aforementioned defects and disadvantages in the art, either alone or in any combination. The invention as defined herein at least partially satisfies these and other objects. Preferred embodiments are described herein.

[0006] According to a first aspect, a truck body is provided, comprising: a main truck body structure for carrying a load, the main truck body structure extending upward at a corresponding upper edge portion on a lateral side of the main truck body structure to prevent the load from leaving the truck body laterally; and a front wall;

[0007] The main truck body structure has an inner surface; and

[0008] The main liner, comprising a plurality of resilient liner elements and disposed on the inner surface of the main truck body structure, wherein

[0009] The main truck body structure includes corresponding reinforcing elements, each of which is integrally formed with the main truck body structure and extends along its corresponding upper edge portion;

[0010] Each reinforcing element has a lining protection portion that protrudes inward beyond the inner surface of the main truck body structure;

[0011] The main lining has a corresponding upper lining edge, which is located directly below the corresponding lining protection portion;

[0012] Each reinforcing element extends in a corresponding reinforcing plane and is able to both reinforce the main truck body structure and form an upper liner protection against the main liner through the liner protection portion.

[0013] The advantages gained by incorporating reinforcing elements within the main truck body structure are comprehensive. As described above, the reinforcing elements both strengthen the sidewalls and form an upper lining protection against the main lining. Consequently, the lining elements of the main truck body structure no longer require integrated steel end protection, resulting in lower production costs and reduced installation time. The reduced installation time is achieved by eliminating the step of welding the integrated steel end protection to the truck body.

[0014] By placing reinforcing elements along the upper edge of the main truck body structure, it is possible to protect the lining elements all the way to the main truck body structure on each lateral side.

[0015] The corresponding upper edge portion extends from the rear end of the main truck body structure to the front wall.

[0016] According to some embodiments, each reinforcing element has a reinforcing element extension in the corresponding reinforcing plane that transverses to the extension of its associated upper edge portion, the reinforcing element extension being at least five times the thickness of the upper lining edge.

[0017] This can be advantageous because it allows for a relatively high upper steel structure for the truck body at a level where the need for protective lining elements is not too high. Therefore, the use of linings can be optimized, i.e., reduced lining usage in the upper part of the truck body where wear is less severe. This further allows for maximizing the load-bearing capacity of the truck body without compromising its abrasion resistance. These relative dimensions of the reinforcing elements effectively allow for an upper protective frame that defines the top opening of the truck body and increases the structural integrity of the main truck body structure.

[0018] However, it is conceivable to provide reinforcing elements of other sizes. As an example, the reinforcing element extension can be shorter, for example, at least 2, 3, or 4 times the thickness of the upper liner edge. Alternatively, the reinforcing element extension can be longer, for example, 5, 10, or 20 times (the thickness of the upper liner edge). For example, the reinforcing element extension can be in the range of 1-2 meters. Alternatively, the reinforcing element extension can be shorter. As an example, the reinforcing element extension can be 2 to 20 mm. This means that the reinforcing element can be a vane or rim. Such a vane can be, for example, a steel plate welded integrally with the truck body structure.

[0019] Truck bodies can be designed for use on articulated trucks. In other words, a truck body can be an articulated truck body. As will be readily understood by those skilled in the art, an articulated truck consists of two parts: a front tractor unit and a trailer, with the truck bed carried by the trailer. Unlike rigid trucks (unibody trucks), articulated trucks have a pivot joint between the front tractor unit and the trailer, allowing the vehicle to turn more sharply and maintain stability on rough terrain. Articulated trucks may have three or more axles. The truck body and its payload are typically mounted on the trailer, which may have two or more axles, separated from the front tractor unit, which has one or more axles, by a pivot joint. Articulated trucks typically have hoist cylinders connected to the sides of the truck body. Articulated trucks can be off-road trucks, commonly used in construction, earthmoving, mining, quarrying, infrastructure projects, and forestry. Therefore, the truck body disclosed herein can be an "off-road articulated truck body," also referred to herein as an "articulated trailer truck body." Alternatively, the articulated truck can also be a highway truck, typically used for construction and road work, etc. Therefore, alternatively, the truck body disclosed herein can be a "highway articulated truck body."

[0020] The main difference between off-road rigid trucks and off-road articulated trucks lies in size. Off-road rigid trucks are typically much larger, with payload capacities ranging from 35 to 450 tons, while off-road articulated trucks are generally smaller, with payload capacities ranging from 15 to 65 tons. The dimensions of an articulated off-road truck body may be 2000-4000 / 4000-8000 / 1000-2500 mm (W / L / H), and the SAE 2:1 stack size ranges from 10 m³. 3 up to 35m 3 The dimensions of a rigid off-road tractor truck body are typically 3600-10000 / 8000-14000 / 2500-5000 mm (W / L / H), with a SAE 2:1 stack size of 25 m³. 3 up to 300m 3 Rigid off-road tractor trucks have a rigid chassis with a non-flexible frame. They are commonly used in mining, quarrying, and large infrastructure projects. Rigid tractor trucks typically have two axles, with the body and payload positioned between them, resulting in a weight distribution of approximately 33% at the front and 67% at the rear. They also typically feature a lift cylinder that connects to the underside of the truck body.

[0021] In other words, the truck body disclosed herein can be used in both off-road and on-road articulated trucks. However, the truck body disclosed herein should not be construed as being limited to articulated trucks. Alternatively, the truck body disclosed herein can be used in rigid trucks.

[0022] As used herein, the term "integral formation" and variations thereof will be interpreted as a component molded into a single part, or a component consisting of multiple parts attached to each other, for example, by welding.

[0023] According to some embodiments, the respective reinforcing element planes are substantially parallel to each other. As used herein, this should be interpreted as the respective reinforcing element planes being arranged relative to each other within + / - 5°. Alternatively, the respective reinforcing element planes are not parallel to each other. The respective reinforcing element planes may form an angle between each other in the range of 1° to 30°.

[0024] Each lining protection portion may protrude beyond the upper lining edge of the main lining by a distance at least equal to the thickness of the upper lining edge. However, it is conceivable to have even greater overlap, such that the lining protection portions protrude beyond and beyond the upper lining edge. Therefore, in an alternative embodiment, each lining protection portion may protrude beyond the upper edge of the main lining by a distance at least equal to 1.0 to 1.5 times the thickness of the upper lining edge. Providing lining protection portions that protrude beyond and beyond the upper lining edge can be advantageous because it can further reinforce the sidewalls and provide further protection for the main lining.

[0025] According to some embodiments, the main truck body structure includes a bottom and two opposing sidewalls, each of which has a corresponding upper edge portion. As used herein, the term "bottom" is used to define the portion of the main truck body structure that primarily serves as the load-bearing surface of the truck body, while the term "sidewall" is used to define the portion of the main truck body structure that primarily serves to prevent loads from falling off the bottom. This means that the bottom is generally horizontally arranged, while the sidewalls have extensions having vertical members.

[0026] It should be understood that, alternatively, the truck body of this disclosure may have a less well-defined shape. As an example, the truck body of this disclosure may have a curved main truck body structure to achieve load support and load restraint functions. Such a truck body may have a main truck body structure that follows a single curved path between corresponding upper edge portions. Such a truck body may, for example, have a semi-cylindrical shape.

[0027] According to some embodiments, each of the opposing sidewalls follows a curved path along at least a portion of its extension from the bottom to its corresponding upper edge portion.

[0028] According to some embodiments, each of the opposing sidewalls follows a planar path along at least a portion of its extension from the bottom to its corresponding upper edge portion.

[0029] According to some embodiments, the bottom follows a curved path between opposing sidewalls along at least a portion of the extension.

[0030] According to some embodiments, the bottom follows a planar path between opposing sidewalls along at least a portion of the extension.

[0031] According to some embodiments, each sidewall includes a lower portion connected to the bottom, wherein the lower portion forms a slope angle relative to the upper edge portion at their intersection. The slope angle can be in the range of 115° to 160°, or 120° to 155°, or 125° to 150°, or 130° to 145°, or 130° to 140°, or approximately 135°. The sloped lower portion can provide a generally tapered shape for the truck body. This tapered shape can be advantageous because it creates space at the bottom of the truck body, freeing up space for the truck tires. This allows the truck body to be mounted at a lower position on the truck chassis, thus reducing the overall height of the truck and providing a lower center of gravity.

[0032] In some embodiments, the lower portion is connected to the bottom via a curved transition section. This prevents the load from getting stuck in the corners of the truck body.

[0033] According to some embodiments, the lining protection portion and the corresponding upper lining edge located below it protrude substantially perpendicular to the inner surface of the main truck body structure.

[0034] According to some embodiments, the reinforcing element is divided into two or more reinforcing element units.

[0035] According to some embodiments, each reinforcing element has a double-walled structure with a hollow interior. This provides a robust yet lightweight solution.

[0036] According to some embodiments, the front wall also includes a reinforcing element integrally formed with the front wall and extending along the upper edge portion of the front wall.

[0037] The reinforcing element can be divided into two or more reinforcing element units.

[0038] The front wall may be covered by a front wall liner. The front wall liner may include multiple resilient liner elements.

[0039] According to the second aspect, a truck is provided, which includes the truck body according to the first aspect.

[0040] The effects and features of the second aspect are largely similar to those described above in conjunction with the first aspect. The embodiments mentioned in the first aspect are largely compatible with the second aspect. It should also be noted that the concept of this invention encompasses all possible combinations of features unless otherwise expressly stated.

[0041] The further applicability of this disclosure will become apparent from the detailed description given below. However, it should be understood that while the detailed description and specific examples indicate preferred embodiments of this disclosure, they are given by way of illustration only, as various changes and modifications within the scope of this disclosure will become apparent to those skilled in the art from this detailed description.

[0042] Therefore, it should be understood that this disclosure is not limited to the specific components of the described device, as the device can vary. It should also be understood that the terminology used herein is merely for describing particular embodiments and not for limitation. It must be noted that, as used in the specification and appended claims, the articles “a,” “an,” “the,” and “said” are intended to indicate the presence of one or more elements unless the context clearly indicates otherwise. Thus, for example, references to “a unit” or “the unit” can include several devices, etc. Furthermore, the words “comprising,” “including,” “containing,” and similar wording do not exclude other elements or steps.

[0054] This disclosure will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the disclosure are illustrated. However, this disclosure may be implemented in many different forms and should not be construed as limiting itself to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully communicate the scope of this disclosure to those skilled in the art.

[0055] Figure 1 An exemplary embodiment of a truck 1 is shown, the truck 1 including a trailer truck body 2 made of metal material, the trailer truck body including a liner. Figure 1The truck 1 shown is an articulated truck. As will be readily understood by those skilled in the art, an articulated truck consists of two parts (a front tractor unit 30 and a trailer 31). Unlike rigid trucks, articulated trucks have a pivot joint A between the front tractor unit 30 and the trailer 31, allowing the vehicle to turn more sharply and maintain stability on rough terrain. Articulated trucks may have three axles 4a, 4b, or more. The truck body 2 and its payload are typically positioned on the trailer 31, which may have two axles 4b or more, separated from the front tractor unit 30, which has one or more axles, by the pivot joint A. Articulated trucks typically have lifting cylinders 32 connected to the sides of the truck body 2. Articulated trucks can be off-road trucks and are commonly used in construction, earthmoving, mining, quarrying, infrastructure projects, and forestry. Therefore, the truck bodies 2, 100, 200, and 300 of this disclosure can be "off-road articulated truck bodies," also referred to herein as "articulated trailer truck bodies." Alternatively, the articulated truck 1 can be a highway truck, typically used for construction and road work, etc. Therefore, alternatively, the truck bodies 2, 100, 200, and 300 of this disclosure can be "highway articulated truck bodies."

[0056] The main difference between off-road rigid trucks and off-road articulated trucks lies in size. Off-road rigid trucks are typically much larger, with payload capacities ranging from 35 to 450 tons, while off-road articulated trucks are generally smaller, with payload capacities ranging from 15 to 65 tons. The dimensions of an articulated off-road truck body may be 2000-4000 / 4000-8000 / 1000-2500 mm (W / L / H), and the SAE 2:1 stack size ranges from 10 m³. 3 up to 35m 3 The dimensions of a rigid off-road tractor truck body are typically 3600-10000 / 8000-14000 / 2500-5000 mm (W / L / H), with a SAE 2:1 stack size of 25 m³. 3 -300m 3 Rigid off-road tractor trucks have a single rigid chassis with a non-flexible frame. Rigid trucks are typically used in mining, quarrying, and large infrastructure projects. Rigid trucks usually have two axles, with the body and payload positioned between them, resulting in a weight distribution of approximately 33% at the front and 67% at the rear. Rigid tractor trucks typically have a lift cylinder that connects to the underside of the truck body.

[0057] In other words, the truck bodies 2, 100, 200, and 300 of this disclosure can be used in both off-road and on-road articulated trucks 1. However, the truck bodies 2, 100, 200, and 300 of this disclosure should not be construed as being limited to articulated trucks 1. Alternatively, the truck bodies 2, 100, 200, and 300 of this disclosure can be used in rigid trucks.

[0058] exist Figures 2-6B An exemplary embodiment of the truck body 2 is shown in more detail below. The truck body 2 includes a main truck body structure 20 for carrying a load. This load can be, for example, sand, stones, gravel, ore, etc., but alternatively, it can be other kinds of materials and / or articles. The main truck body structure 20 extends upward at a corresponding upper edge portion 8 on its lateral side 21 to prevent the load from leaving the truck body 2 laterally. The truck body has a front wall 5, which defines the front portion of the truck body 2. The main truck body structure 20 extends from the front wall 5 to its rear end 9. Figures 2-4 As shown, the corresponding upper edge portion 8 also extends from the front wall 5 to the rear end 9. The main truck body structure 20 has an inner surface 7.

[0059] like Figure 2 and Figure 5 As best illustrated, the exemplary embodiment of the main truck body structure 20 includes a bottom 15 and two opposing side walls 6. Each of the opposing side walls 6 has a corresponding upper edge portion 8. Each of the opposing side walls 6 follows a curved path along at least a portion of its extension from the bottom 15 to its corresponding upper edge portion 8. Each of the opposing side walls 6 follows a planar path along at least a portion of its extension from the bottom 15 to its corresponding upper edge portion 8. For the exemplary embodiment, each side wall 6 includes a lower side portion 22 connected to the bottom 15, wherein the lower side portion 22 forms an angle V relative to the upper edge portions 8 at their intersection, see [reference needed]. Figure 5 The tilt angle V can be in the range of 115° to 160°, or 120° to 155°, or 125° to 150°, or 130° to 145°, or 130° to 140°, or approximately 135°. For this example embodiment, the tilt angle V is 135°. Figure 5 As shown, the lower portion 22 is connected to the bottom 15 via a curved transition portion 23.

[0060] The main liner 12 is arranged to cover the inner surface 7 of the main truck body structure 20. The main liner 12 includes a plurality of resilient liner elements 3a, 3b, and 3c. Liner elements 3a, 3b, and 3c may include rubber or polyurethane, etc. Liner elements 3a, 3b, and 3c may also include steel inserts to provide structural strength. Liner elements 3a, 3b, and 3c can be fastened to the main truck body structure 20 by means of fastening bolts, etc. Figure 5 As best shown, the main lining 12 may include lining elements of different sizes and thicknesses. Lining element 3a is used on the sidewall 6 and has a thickness W1, while lining element 3b is used on the bottom 15 and has a thickness W2. Figure 5As best illustrated, thickness W1 is less than thickness W2. The thickness of lining elements 3a and 3b is typically at least 30 mm. Typically, and by way of example only, the thickness of lining element 3b disposed at the bottom 15 and corners is 50 to 150 mm, while the thickness of lining element 3a disposed on the sidewall 6 is between 30 and 130 mm. Lining elements 3a and 3b are planar, while lining element 3c disposed on the curved transition portion 23 is also curved to follow the curved shape of the curved transition portion 23 and to provide a smooth transition between lining elements 3a and lining element 3b. In an exemplary embodiment, lining element 3c has the same thickness W2 as lining element 3b. However, it is conceivable to provide lining element 3c with a different thickness, such that it has thickness W2 at its intersection with lining element 3b and thickness W1 at its intersection with lining element 3a. This advantageously eliminates any edges and / or recesses on the lining surface.

[0061] The main truck body structure 20 also includes corresponding reinforcing elements 10, each integrally formed with the truck body structure 20 and extending along its upper edge portion 8. Each reinforcing element 10 has a lining protection portion 11 that projects inwardly beyond the inner surface 7 of the main truck body structure 20. The main lining 12 has a corresponding upper lining edge 13 located directly below the corresponding lining protection portion 11. This is in Figure 6A and Figure 6B As best shown in the diagram. Each reinforcing element 10 can both reinforce the main truck body structure 20 and form an upper lining protection for the main lining 12 through the lining protection portion 11.

[0062] like Figure 2 As shown, each reinforcing element 10 extends in a corresponding reinforcing element plane P1, P2, and has a reinforcing element extension E1, E2 within said plane P1, P2, which is transverse to the extension T1, T2 of its associated upper edge portion 8. The reinforcing element extensions E1, E2 are at least five times the thickness W1 of the upper lining edge 13. For an exemplary embodiment, the corresponding reinforcing element planes P1 and P2 are substantially parallel to each other. However, it is also conceivable that the reinforcing element planes P1 and P2 are at an angle relative to each other.

[0063] like Figure 6B As best illustrated, each lining protection portion 11 may protrude beyond the upper lining edge 13 of the main lining 12 by a distance W3 at least equal to the thickness W1 of the upper lining edge 13. However, it is conceivable to have even greater overlap, such that the lining protection portion 11 protrudes beyond and beyond the upper lining edge 13. Therefore, in an alternative embodiment, each lining protection portion 11 may protrude beyond the upper lining edge 13 of the main lining 12 by a distance at least equal to 1.0 to 1.5 times the thickness W1 of the upper lining edge 13.

[0064] like Figure 6A and Figure 6B As best shown, the lining protection portion 11 and the corresponding upper lining edge 13 located below it protrude substantially perpendicularly to the inner surface 7 of the truck body structure 20.

[0065] The reinforcing element 10 can be divided into two or more reinforcing element units. In such an exemplary embodiment, two or more reinforcing element units can be individually attached to the main truck body structure 20, for example, by welding, thereby providing a reinforcing element 10 extending from the front wall 5 to the rear end 9. Figure 5 , Figure 6A and Figure 6B As best shown, each reinforcing element 10 can have a double-walled structure 10a, 10b with a hollow interior 24. This provides a robust yet lightweight solution.

[0066] like Figure 3 As best shown, the front wall 5 may further include a reinforcing element 25 integrally formed with the front wall 5 and extending along the upper edge portion 26 of the front wall 5. The reinforcing element 25 may be divided into two or more reinforcing element units. In an exemplary embodiment, the reinforcing element 25 forms part of the canopy 18. The front wall 5 may be covered by a front wall liner 17. The front wall liner 17 may include a plurality of liner elements 3. In an exemplary embodiment, the front wall liner 17 may include elastomeric liner elements 3 of the same kind as the elastomeric liner elements (i.e., liner elements 3a) disposed on the side walls 6. Thus, typically, the thickness of the liner elements 3 disposed on the front wall is between 30 mm and 130 mm. However, it is conceivable to provide alternative liner elements, such as non-elastic liner elements. Such non-elastic liner elements may be, for example, steel liner elements.

[0067] The reinforcing element 25 has a lining protection portion 27 that protrudes inward beyond the inner surface of the front wall 5. The lining protection portion 27 can protrude beyond the upper edge of the lining element 3 constituting the front wall lining 17 by a distance at least equal to the thickness of the lining element 3, such as... Figure 3 The exemplary embodiments are shown. However, it is conceivable that there is even greater overlap, such that the liner protection portion 27 protrudes beyond and beyond the upper edge of the liner element 3, as also described with reference to the liner protection portion 10 extending along the upper edge portion 8 of the main truck body structure 20.

[0068] According to a first manufacturing method of the truck body 2, the main truck body structure 20 and the front wall 5 are molded together as a single piece with reinforcing elements 10 and optional reinforcing elements 25, such that each reinforcing element 10 protrudes inward beyond the inner surface 7 of the main truck body structure 20. Subsequently, the trailer truck body 2 has a main liner 12 provided on the inner surface 7 of the main truck body structure 20 and a front wall liner 17 provided on the front wall 5.

[0069] Alternatively, the main truck body structure 20 and the front wall 5 are formed separately. Again, alternatively, the bottom 15, side walls 6, and front wall 5 are all formed separately. Thereafter, reinforcing element 10 is formed and attached to the main truck body structure 20 of the trailer truck body 2. Optionally, reinforcing element 25 is formed and attached to the main truck body structure 20. As a final step, the trailer truck body 2 has a main liner 12 provided on the inner surface 7 and a front wall liner 17 provided on the front wall 5 in the same manner as described above.

[0070] The main truck body structures 20, 120, 220, and 320 disclosed herein may have alternative shapes. Figures 7A to 7C Three alternative, non-limiting examples are schematically illustrated. These figures show cross-sections of truck bodies 100, 200, and 300 in front views according to the alternative embodiments of this disclosure. In these figures, the same features have the same reference numerals. Those skilled in the art will recognize that the front wall (not shown) must naturally correspond geometrically to the corresponding shape of the main truck body structure, and is therefore not shown here.

[0071] Figure 7A A cross-sectional view of a truck body 100 according to an alternative embodiment of the present disclosure is shown. The truck body 100 differs from the truck body 2 in that the main truck body structure 120 is semi-cylindrical. Therefore, the inner surface 107 of the main truck body structure 120 follows a curved path along its entire extension from one upper edge portion 108 via the sidewall 106 and bottom 115 to the other upper edge portion 108. Here, the main liner 112 is composed of liner elements 3d, which are designed to be curved, or alternatively, forced into a curved shape when mounted onto the curved inner surface 107. The thickness of the liner element 3d is less than the thickness of the aforementioned liner element 3a. Furthermore, the reinforcing element 110 of the truck body 100 differs from the reinforcing element described in detail for the truck body 2 in that it is a one-piece solid reinforcing element 110. This provides stable reinforcement for the sidewall 106 and the main liner 112. The dimensions of the solid reinforcing element 110 can be compared with those of the referenced... Figure 2 The dimensions of the described reinforcing element 10 are substantially the same. From... Figure 7A As can be seen, the lining protection portion 11 protrudes beyond and extends beyond the upper lining edge 113. This provides better protection for the main lining 112.

[0072] Figure 7B A cross-sectional view of a truck body 200 according to an alternative embodiment of the present disclosure is shown. The truck body 200 is compared with a reference... Figure 7A The truck body 100 described differs only in that the main truck body structure 220 has different dimensions on the reinforcing elements 210 at their upper edge portions 208 on each opposing side wall 206. The remaining features are the same. Figure 7A The truck body 100 is identical. Specifically, the inner surface 207 of the main truck body structure 220 also follows a curved path along its entire extension from one upper edge portion 208 via the sidewalls 206 and bottom 215 to another upper edge portion 208, and the same main lining 112 covers the inner surface 207. Moving to a different point, Figure 7B Each reinforcing element 210 is shown to have reinforcing element extensions E1, E2, which are approximately twice the thickness W1 of the upper lining edge 113. Therefore, the extensions E1, E2 of the reinforcing element 210 of the truck body 200 are shorter than the extensions E1, E2 of the truck body 100.

[0073] Figure 7C A cross-sectional view of a truck body 300 according to yet another alternative embodiment of the present disclosure is shown. The truck body 300 is compared with a reference... Figure 7A The truck body 100 described differs only in that the main truck body structure 320 has a different shape. Specifically, the main truck body structure 320 has a rounded bottom 315, which is interconnected with a substantially flat sidewall 306 via a curved transition portion 323. The sidewall 306 is connected to a reinforcing element 310 at a corresponding upper edge portion 308, the reinforcing element 310 being similar to the reference [reference image]. Figure 7A The described truck body 100 has a reinforcing element, but differs in that the lining protection portion 311 is angled so as to project substantially perpendicularly to the inner surface 307 of the main truck body structure 320. The angle V can be in the range of 115° to 160°, or 120° to 155°, or 125° to 150°, or 130° to 145°, or 130° to 140°, or approximately 135°. For Figure 7C In the example embodiment shown, the tilt angle V is 155°. The main lining 312 is distributed on the inner surface 307 and includes two lining elements 3a and 3e. Lining element 3a is compared with the reference... Figure 2 The lining element used on the truck body 2 described is the same, while the lining element 3e is curved.

[0074] It should be understood that other variations can be conceived in this invention, and in some cases, certain features of this invention can be used without corresponding use of other features. Therefore, it is appropriate to interpret the appended claims broadly in a manner consistent with the scope of this invention.

[0075] For example, the reinforcing element 10 can be divided into two or more reinforcing element units.

[0076] Naturally, without departing from the scope of this disclosure, the number, size, and shape of the parts of the truck body 2 can be varied in any suitable manner.
