[0031] In addition, although the terms first, second, third, etc. may be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates, terms such as "first" and "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teachings of the exemplary embodiments.

[0032] Such as Figure 2 , Figure 3 and Figure 4The shown integrated truck after-treatment combination bracket 1 is integrally cast from aluminum alloy material. The integrated truck after-treatment combination bracket 1 includes a thrust rod mounting portion 20, an after-treatment assembly mounting portion 10, and a transition connection portion 30. One end of the after-treatment assembly mounting portion 10 is a frame mounting end A for fixedly connecting with the frame 2. The frame mounting end A and the thrust rod mounting portion 20 are connected into one body through the transition connection portion 30.

[0033] A plurality of first bolt mounting holes 101 arranged in a straight line are formed on the after-treatment assembly mounting portion 10. In this embodiment, three first bolt mounting holes 101 are formed on the after-treatment assembly mounting portion 10, and their function is to fix the large after-treatment assembly C on the combination bracket 1 through bolts and nuts, providing support for the fixation of the large after-treatment assembly C.

[0034] The end face of the frame mounting end A is a first frame mounting fitting surface 100. A second frame mounting fitting surface 201, a third frame mounting fitting surface 202, and a thrust rod mounting hole column 203 are provided on the thrust rod mounting portion 20. The third frame mounting fitting surface 202 is perpendicular to the second frame mounting fitting surface 201.

[0035] A thrust rod mounting hole 2031 is formed on the thrust rod mounting hole column 203.

[0036] As Figure 3 shown, second bolt mounting holes 2011 are respectively formed on the first frame mounting fitting surface 100 and the second frame mounting fitting surface 201. A third bolt mounting hole 2021 is formed on the third frame mounting fitting surface 202. The axis of the third bolt mounting hole 2021 is perpendicular to the axis of the second bolt mounting hole 2011 and the axis of the thrust rod mounting hole 2031.

[0037] The integrated truck after-treatment combination bracket 1 of the present utility model integrates the traditional thrust rod mounting bracket 7 and the after-treatment assembly mounting bracket 6 into one part, reducing the number of brackets and connecting parts, avoiding the situation of unstable product dimensions caused by the assembly of multiple parts, improving product consistency, optimizing the assembly space, and enhancing the installation efficiency. The integrated truck after-treatment combination bracket is integrally cast from lightweight aluminum alloy material, and the product is optimized in mold flow process and analyzed by structural finite element during the development stage to ensure the stable function of the product within the life cycle. Using aluminum alloy material instead of the original cast iron material reduces the product weight, with a weight reduction rate of about 53%, which is of positive significance for energy conservation and emission reduction.

[0038] As Figure 2 and Figure 3As shown, the post-processor assembly mounting portion 10 includes an upper connecting arm plate 102, a lower connecting arm plate 103, and an intermediate connecting structure. The intermediate connecting structure is located between the upper connecting arm plate 102 and the lower connecting arm plate 103 and is connected to both. The upper connecting arm plate 102 and the lower connecting arm plate 103 are plates with equal wall thicknesses, and their shapes are designed according to the loading characteristics and the arrangement of surrounding parts in the assembly space, and sufficient safety space should be left.

[0039] As Figure 4 shown, the transition connecting portion 30 includes an outer connecting plate 301 and an inner arc-shaped transition plate 302. The two ends of the outer connecting plate 301 are respectively connected to the upper connecting arm plate 102 and the thrust rod mounting portion 20, and the two ends of the inner arc-shaped transition plate 302 are respectively connected to the lower connecting arm plate 103 and the thrust rod mounting portion 20. The functions of the outer connecting plate 301 and the inner arc-shaped transition plate 302 are to provide a transition between the post-processor assembly mounting portion 10 and the thrust rod mounting portion 20, and at the same time, they can also improve the connection stiffness between the two parts. The inner arc-shaped transition plate 302 has a large-round-corner transition shape, and the circular structure can slow down stress concentration to the greatest extent. Its shape design also takes into account the factor of the safety clearance of surrounding parts to avoid interference with the post-processor assembly during movement.

[0040] As Figure 2 shown, the intermediate connecting structure includes a reinforcing cylindrical rib 104, and first bolt mounting holes 101 are opened on the upper connecting arm plate 102 and the lower connecting arm plate 103 corresponding to the reinforcing cylindrical rib 104.

[0041] As Figure 2 and Figure 3 shown, the intermediate connecting structure includes a connecting vertical baffle 105, a plurality of first diagonal reinforcing ribs 106, and a plurality of second diagonal reinforcing ribs 107. The plurality of first diagonal reinforcing ribs 106 and the plurality of second diagonal reinforcing ribs 107 are respectively located on both sides of the connecting vertical baffle 105. The settings of the first diagonal reinforcing ribs 106 and the second diagonal reinforcing ribs 107 greatly improve the overall stiffness of the post-processor assembly mounting portion 10 and reduce the deformation caused by external loads. Moreover, the plurality of first diagonal reinforcing ribs 106 and the plurality of second diagonal reinforcing ribs 107 provide channels for the flow of molten iron during casting, making the product easier to form.

[0042] As Figure 5 and Figure 6As shown, the thrust rod mounting portion 20 is provided with two thrust rod fracture limiting surfaces 204. The two thrust rod fracture limiting surfaces 204 are separately arranged and are respectively close to both ends of the thrust rod mounting hole column 203. The thrust rod mounting portion 20 is provided with fracture limiting surface reinforcing ribs 205, and the fracture limiting surface reinforcing ribs 205 are close to the thrust rod fracture limiting surfaces 204. For safety considerations, when the thrust rod 3 breaks due to external force during driving, in order to prevent the thrust rod 3 from dragging on the ground, a thrust rod fracture limiting surface 204 is provided on the integrated truck aftertreatment combination bracket 1, and its function is to provide limiting support for the thrust rod retaining piece 5. The fracture limiting surface reinforcing ribs 205 improve the strength of the thrust rod fracture limiting surfaces 204 and prevent them from breaking due to the violent impact of the thrust rod 3.

[0043] As Figure 4 shown, the thrust rod mounting portion 20 is provided with reinforcing ribs 206 on both sides of the hole column. The reinforcing ribs 206 on both sides of the hole column are respectively connected to the circumferential surface of the thrust rod mounting hole column 203 and are located on both sides of the thrust rod mounting hole column 203.

[0044] The beam mounting end is provided with end reinforcing ribs 207. The end reinforcing ribs 207 connect the upper connecting arm plate 102 and the beam mounting end A. The shape of the end reinforcing ribs 207 is a triangular structure, and its function is to provide strength support for the second bolt mounting hole 2011 and the aftertreatment assembly mounting portion 10 on the first beam mounting mating surface 100. Because according to the load-bearing principle, the joint part between the beam mounting end A and the aftertreatment assembly mounting portion 10 is the place where the structure is subjected to the greatest force. Providing a reinforcing rib at this place can effectively relieve stress concentration and avoid excessive stress at the root of the joint.

[0045] The thrust rod mounting portion 20 is provided with a material escape groove 208. The material escape groove 208 is located at the second beam mounting mating surface 201. The material escape groove 208 is for reducing the overall weight.

[0046] As Figure 6 shown, for the integrated truck aftertreatment combination bracket 1 of the present invention, its aftertreatment assembly mounting portion 10 is fixedly connected to the aftertreatment large package assembly C through bolts and nuts D. The thrust rod mounting portion 20 is fixedly installed on the beam 2 through bolts and nuts. The thrust rod 3 is installed at the thrust rod mounting hole column 203 through the thrust rod retaining piece 5.

[0047] In summary, the integrated truck aftertreatment combination bracket of the present invention has a compact structure, a high degree of integration, a light weight, and is structurally stable, and is convenient and fast to install and disassemble.

[0048] The technical solution of the present utility model has been described in detail in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Those skilled in the art should understand that various changes made in terms of form and details fall within the protection scope defined by the claims of the present utility model.
