The exhaust pipe is rigidly connected to the aftertreatment assembly by screws, and the tailpipe is connected to the exhaust pipe. During operation, the aftertreatment assembly treats the exhaust gases emitted by the engine, and then the exhaust gases within the aftertreatment assembly are discharged through the exhaust pipe and tailpipe.
[0004] However, during use, the exhaust pipe and tailpipe together form a long cantilever, making the connection between the aftertreatment assembly and the exhaust pipe prone to fatigue and breakage, which in turn leads to exhaust system failure. Utility Model Content
[0005] This application provides an exhaust system and a loader to solve the problem in the prior art that the connection between the aftertreatment assembly and the exhaust pipe is prone to fatigue fracture after long-term use, which leads to exhaust system failure.
[0006] On one hand, this application provides an exhaust system, including:

[0011] The connecting pipe is inserted into one end of the exhaust pipe in the direction of extension, and there is a gap between the outer wall of the connecting pipe and the inner wall of the exhaust pipe.
[0012] In one possible implementation, the gap between the outer wall of the connecting pipe and the inner wall of the exhaust pipe is D, where D ≤ 8 mm.
[0013] In one possible implementation, the docking component further includes a mounting base on which the docking tube is disposed, and the mounting base is connected to the aftertreatment assembly.
[0014] In one possible implementation, the support includes a bracket and a clamp, the clamp being detachably connected to the bracket and clamping the exhaust pipe onto the bracket;
[0015] The bracket is connected to the post-processing assembly.
[0016] In one possible implementation, a tailpipe is also included, one end of which is connected to the other end of the exhaust pipe in the direction of extension.
[0017] In one possible implementation, the tailpipe has a tapered portion at one end facing the exhaust pipe, the larger end of the tapered portion facing the exhaust pipe, the other end of the exhaust pipe extending in the direction of extension being inserted into the tailpipe from the tapered portion, and there is a gap between the outer wall of the exhaust pipe and the inner wall of the tailpipe.
[0018] In one possible implementation, the length of the exhaust pipe inserted into the tailpipe is L, where 15mm ≤ L ≤ 25mm.
[0019] In one possible implementation, the exhaust pipe has a first connecting section and a second connecting section that are interconnected, the first connecting section being connected to the air outlet and the second connecting section being connected to the tailpipe, the axis of the first connecting section being set at an angle to the axis of the second connecting section.
[0020] On the other hand, this application provides a loader including an engine and an exhaust system as described in any of the above embodiments, wherein the engine is connected to an exhaust pipe, and the exhaust pipe is connected to an aftertreatment assembly in the exhaust system.
[0021] This application provides an exhaust system and a loader, wherein the exhaust system comprises: an aftertreatment assembly for treating exhaust gases emitted from the engine, the aftertreatment assembly having an outlet; an exhaust pipe, one end of which is flexibly connected to the aftertreatment assembly and connected to the outlet; and a support member on which the exhaust pipe is mounted. Thus, during operation, the exhaust gases emitted from the engine are treated by the aftertreatment assembly and then discharged through the exhaust pipe. Furthermore, the exhaust pipe and the aftertreatment assembly are flexibly connected, and the cantilever length of the exhaust pipe is effectively reduced under the support of the support member.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0033] In related technologies, the exhaust system is an important component in equipment such as loaders and diesel engines to ensure that the equipment can operate normally.
[0034] The exhaust system includes an aftertreatment assembly, an exhaust pipe, and a tailpipe. The exhaust pipe and tailpipe are connected to the aftertreatment assembly by a rigid connection with screws. The aftertreatment assembly is used to treat the exhaust gas emitted by the engine, and then the exhaust gas in the aftertreatment assembly is discharged through the exhaust pipe and tailpipe.
[0035] However, during use, the exhaust pipe and tailpipe together form a long cantilever, and the connection between the exhaust pipe and the aftertreatment assembly is susceptible to thermal stress deformation. As a result, after prolonged use, the connection between the aftertreatment assembly and the exhaust pipe is prone to fatigue and breakage, leading to exhaust system failure.
[0036] Therefore, this application provides an exhaust system and a loader. The exhaust system includes: an aftertreatment assembly for treating exhaust gas emitted from the engine, the aftertreatment assembly having an outlet; an exhaust pipe, one end of which is flexibly connected to the aftertreatment assembly and connected to the outlet; and a support member on which the exhaust pipe is mounted. Thus, during operation, the exhaust gas emitted from the engine is treated by the aftertreatment assembly and then discharged through the exhaust pipe. Furthermore, the exhaust pipe and the aftertreatment assembly are flexibly connected, and the cantilever length of the exhaust pipe is effectively reduced under the support of the support member. This reduces the possibility of fatigue fracture at the connection between the exhaust pipe and the aftertreatment assembly due to prolonged use, solving the problem in the prior art where the connection between the aftertreatment assembly and the exhaust pipe is prone to fatigue fracture after prolonged use, leading to exhaust system failure.
[0037] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.
[0038] like Figure 1 As shown in the embodiment of this application, an exhaust system includes:
[0039] The aftertreatment assembly 100 is used to treat the exhaust gas emitted by the engine, and the aftertreatment assembly 100 has an exhaust port 110.
[0040] The exhaust pipe 200 has one end extending in the direction of flexible connection to the aftertreatment assembly 100, and the end extending in the direction of exhaust pipe 200 is connected to the air outlet 110.
[0041] Support member 300, exhaust pipe 200 is mounted on support member 300.
[0042] It should be noted that the aftertreatment assembly 100 can be an existing product, and its specific structure is not limited. In implementation, the aftertreatment assembly 100 can be connected to the exhaust pipe on the engine so that the exhaust gas generated by the engine is treated by the aftertreatment assembly 100 before being discharged.
[0043] The working principle is as follows: When the engine is running, the exhaust gas produced by the engine enters the aftertreatment assembly 100. After undergoing catalytic oxidation by the DOC (diesel oxidation catalyst) and particulate capture by the DPF (diesel particulate filter) in the aftertreatment assembly 100, the exhaust gas that meets the emission requirements flows into the exhaust pipe 200 through the outlet 110 and is then discharged to the outside. In other words, the aftertreatment assembly 100 can effectively reduce harmful substances such as carbon monoxide and hydrocarbons in the exhaust gas.
[0044] The support member 300 can be mounted on the aftertreatment assembly 100 or on a surrounding object, and the exhaust pipe 200 is then mounted on the support member 300. In other words, the exhaust pipe 200 is supported by the support member 300, allowing it to maintain a relatively stable and flexible connection with the aftertreatment assembly 100 under the action of the support member 300. The specific fixed position of the support member 300 is not limited.
[0045] During operation, the flexible connection between the exhaust pipe 200 and the aftertreatment assembly 100 reduces the impact of axial displacement, radial sway, and thermal stress deformation on the connection point during use. Furthermore, the support of the support member 300 effectively reduces the cantilever length of the exhaust pipe 200. This reduces the likelihood of fatigue fracture at the connection point between the exhaust pipe 200 and the aftertreatment assembly 100 due to prolonged use, solving the problem in existing technologies where the connection point between the aftertreatment assembly 100 and the exhaust pipe 200 is prone to fatigue fracture after prolonged use, leading to exhaust system failure.
[0046] In addition, the strain acquisition and fatigue testing process during the development of the exhaust pipe 200 can be simplified, the development cycle can be shortened, and the development cost can be reduced.
[0047] like Figure 1 and Figure 2 As shown, in some embodiments, the exhaust system further includes a docking member 400, which includes a connecting pipe 410. One end of the connecting pipe 410 extends into the aftertreatment assembly 100, and the other end of the connecting pipe 410 extends into the exhaust port 110.
[0048] The connecting pipe 410 is inserted into one end of the exhaust pipe 200 in the extending direction, and there is a gap between the outer wall of the connecting pipe 410 and the inner wall of the exhaust pipe 200.
[0049] Specifically, the connecting pipe 410 is installed on the aftertreatment assembly 100, and one end of the connecting pipe 410 in the extension direction is connected to the aftertreatment assembly 100. The other end of the connecting pipe 410 in the extension direction extends outward from the aftertreatment assembly 100, so that the end of the connecting pipe 410 away from the aftertreatment assembly 100 forms an air outlet 110.
[0050] Secondly, the diameter of the connecting pipe 410 is smaller than that of the exhaust pipe 200, so that the end of the connecting pipe 410 away from the aftertreatment assembly 100 can be inserted into the exhaust pipe 200; and there is a gap between the outer wall of the connecting pipe 410 and the inner wall of the exhaust pipe 200, which is an annular gap.
[0051] Therefore, the aftertreatment assembly 100 is flexibly connected to the exhaust pipe 200 through the connecting pipe 410. Compared with the aftertreatment assembly 100 and the exhaust pipe 200 being rigidly connected by screws, this can reduce the possibility of fatigue fracture at the connection between the exhaust pipe 200 and the aftertreatment assembly 100 due to long-term use.
[0052] Furthermore, the gap between the outer wall of the connecting pipe 410 and the inner wall of the exhaust pipe 200 is D, where D≤8mm.
[0053] In this embodiment, the gap D between the connecting pipe 410 and the exhaust pipe 200 refers to the annular gap between the outer wall of the connecting pipe 410 and the inner wall of the exhaust pipe 200. In practice, D can be set to 2mm, 3mm, 5mm, 6mm, 7mm, 8mm, or other values; preferably, 5mm ≤ D ≤ 8mm.
[0054] Therefore, during the exhaust process, the exhaust gas output from the aftertreatment assembly 100 will form a jet in the exhaust pipe 200, resulting in a higher airflow velocity and lower pressure. Consequently, an ejector effect will be formed in the gap between the exhaust pipe 200 and the aftertreatment assembly 100, which will have a suction effect on the gas outside the exhaust pipe 200, thereby achieving dynamic sealing of the gap and reducing the possibility of exhaust gas leakage in the gap.
[0055] In addition, controlling the gap D to 5~8mm can reduce the installation accuracy requirements while ensuring reliability.
[0056] In other embodiments, a corrugated pipe or other flexible hose may be used to connect the exhaust pipe 200 to the aftertreatment assembly 100, thereby achieving a flexible connection between the exhaust pipe 200 and the aftertreatment assembly 100.
[0057] like Figure 2 As shown, in some embodiments, the docking member 400 further includes a mounting base 420, on which the docking pipe 410 is disposed, and the mounting base 420 is connected to the post-processing assembly 100.
[0058] In this embodiment, the mounting base 420 is a plate-like structure. Of course, the mounting base 420 can also be a block-like, bracket-like, or other shape, and there is no limitation thereto. The connecting pipe 410 can be fixed to the mounting base 420 by integral molding, welding, screwing, or other means.
[0059] During installation, the mounting base 420 can be fixed to the aftertreatment assembly 100 by screwing, welding, or other means, so that one end of the connecting pipe 410 extends into the aftertreatment assembly 100, while the other end extends outward toward the aftertreatment assembly 100. Thus, the connecting pipe 410 is installed onto the aftertreatment assembly 100 via the mounting base 420, and then the connecting pipe 410 can be connected to the exhaust pipe 200.
[0060] In some embodiments, the support 300 includes a bracket 310 and a gripper 320, the gripper 320 being detachably connected to the bracket 310, and the gripper 320 clamping the exhaust pipe 200 onto the bracket 310.
[0061] The bracket 310 is connected to the aftertreatment assembly 100.
[0062] In this embodiment, the bracket 310 can be connected to the post-processing assembly 100 by screwing, welding or other means, or it can be connected to objects around the post-processing assembly 100. Preferably, the bracket 310 is connected to the post-processing assembly 100. In addition, there are no restrictions on the shape of the bracket 310.
[0063] Secondly, the clamp 320 is an arc-shaped strip; however, it can also be a block or other shapes. The clamp 320 can be connected to the bracket 310 by screwing, snapping, locking, or other means, and clamps the exhaust pipe 200 onto the bracket 310. This provides support for the exhaust pipe 200, ensuring its stability during installation and use.
[0064] During installation, the bracket 310 can be fixed to the aftertreatment assembly 100 first, then the exhaust pipe 200 can be placed on the bracket 310, ensuring that the exhaust pipe 200 is aligned with the connecting pipe 410. Finally, the clamp 320 is fastened to the bracket 310, and the exhaust pipe 200 is clamped onto the bracket 310 by the clamp 320. Preferably, the middle part of the exhaust pipe 200 is clamped onto the bracket 310.
[0065] In practice, the number of grippers 320 can be set to multiple. For example, two grippers 320 can be set, and the two grippers 320 are distributed at intervals along the extension direction of the exhaust pipe 200, which can further improve the fastening effect on the exhaust pipe 200. Of course, the number of grippers 320 can also be one, three or other, and there is no limitation on this.
[0066] In other embodiments, the multiple grippers 320 can be connected as a whole, so that when the multiple grippers 320 are connected to the bracket 310, it is only necessary to fix the whole formed by the multiple grippers 320, thereby improving the convenience of fixing the grippers 320.
[0067] like Figure 1 and Figure 2 As shown, in some embodiments, the exhaust system further includes a tailpipe 500, one end of which is connected to the other end of the exhaust pipe 200 in the direction of extension.
[0068] Specifically, the tailpipe 500 is located at the end of the exhaust pipe 200 away from the aftertreatment assembly 100. One end of the tailpipe 500 in the extension direction is connected to the other end of the exhaust pipe 200 in the extension direction (i.e., the end of the exhaust pipe 200 away from the aftertreatment assembly 100).
[0069] Therefore, the exhaust gas can be guided through the tailpipe 500, making it easy to set the exhaust gas emission position at a preset location. Of course, in practice, the exhaust gas can also be guided through the tailpipe 500 to other treatment equipment.
[0070] It should be noted that, during implementation, the tailpipe 500 can be fixed to a surrounding object, or it can be fixed to the aftertreatment assembly 100. For example, when the exhaust system is applied to a loader or other vehicle, the tailpipe 500 can also be fixed to the vehicle frame.
[0071] Specifically, the tailpipe 500 has a tapered portion 510 at one end facing the exhaust pipe 200, with the larger end of the tapered portion 510 facing the exhaust pipe 200. The other end of the exhaust pipe 200 extending in the direction of extension is inserted into the tailpipe 500 from the tapered portion 510, and there is a gap between the outer wall of the exhaust pipe 200 and the inner wall of the tailpipe 500.
[0072] It should be noted that the end of the tailpipe 500 facing the exhaust pipe 200 is set as a tapered part 510. The small end of the tapered part 510 is connected to the tailpipe 500, and the two have the same diameter. The large end of the tapered part 510 faces the exhaust pipe 200, and its diameter is larger than that of the tailpipe 500.
[0073] During installation, the tailpipe 500 is fitted onto the other end of the exhaust pipe 200 in the direction of extension (i.e., the end of the exhaust pipe 200 away from the aftertreatment assembly 100), such that the exhaust pipe 200 extends at least partially into the tailpipe 500 from the tapered portion 510, and there is a gap between the peripheral wall of the exhaust pipe 200 and the inner wall of the tailpipe 500.
[0074] This allows for a flexible connection between the exhaust pipe 200 and the tailpipe 500, reducing the possibility of mutual interference between them. Furthermore, the gap between the exhaust pipe 200 and the tailpipe 500 also creates an ejector effect, entraining external gas and achieving a dynamic seal at this gap, reducing the likelihood of exhaust gas leakage.
[0075] In practice, for example, the tapered portion 510 may be provided on the tailpipe 500 by welding, integral molding or other means.
[0076] In some embodiments, the length of the exhaust pipe 200 inserted into the tailpipe 500 is L, where 15mm ≤ L ≤ 25mm. Alternatively, the gap between the outer wall of the exhaust pipe 200 and the inner wall of the tailpipe 500 can also be set to D, where D is also controlled within 5~8mm.
[0077] Therefore, by reasonably controlling the dimensions of the fit between the exhaust pipe 200 and the tailpipe 500, it is possible to ensure that the gap between the exhaust pipe 200 and the tailpipe 500 has a better ejection effect, thereby effectively reducing the possibility of exhaust gas leaking outward from the gap.
[0078] For example, the length L of the exhaust pipe 200 inserted into the tailpipe 500 can be set to 15mm, 16mm, 17mm, 19mm, 23mm, 25mm or other values, preferably L is 25mm.
[0079] It should be noted that the end of the exhaust pipe 200 that extends into the tailpipe 500 can be set as a flat opening structure, which can effectively reduce the possibility of airflow accumulating at the connection between the exhaust pipe 200 and the tailpipe 500, and further ensure the dynamic sealing effect of this gap.
[0080] like Figure 2 As shown, in some embodiments, the exhaust pipe 200 has a first connecting section 210 and a second connecting section 220 that are interconnected. The first connecting section 210 is connected to the air outlet 110, and the second connecting section 220 is connected to the tailpipe 500. The axis of the first connecting section 210 and the axis of the second connecting section 220 are set at an angle.
[0081] Specifically, the exhaust pipe 200 is configured with a curved structure, so that the exhaust pipe 200 has a first connecting section 210 and a second connecting section 220 that are interconnected and extend sequentially. The first connecting section 210 is connected to the air outlet 110, and the second connecting section 220 is connected to the tailpipe 500. The axis of the first connecting section 210 and the axis of the second connecting section 220 are set at an angle.
[0082] Therefore, while guiding the exhaust gas through the exhaust pipe 200, it effectively reduces the possibility that the exhaust back pressure will rise too much after the exhaust gas flows from the aftertreatment assembly 100 into the exhaust pipe 200, causing exhaust gas backflow and thus increasing fuel consumption.
[0083] In summary, the exhaust system provided in this application embodiment, during operation, utilizes a flexible connection between the exhaust pipe 200 and the aftertreatment assembly 100 to minimize the impact of axial displacement, radial sway, and thermal stress deformation on the connection point between the exhaust pipe 200 and the aftertreatment assembly 100 during use. Furthermore, the cantilever length of the exhaust pipe 200 is effectively reduced under the support of the support member 300. This reduces the possibility of fatigue fracture at the connection point between the exhaust pipe 200 and the aftertreatment assembly 100 due to prolonged use, solving the problem in the prior art where the connection point between the aftertreatment assembly 100 and the exhaust pipe 200 is prone to fatigue fracture after prolonged use, leading to exhaust system failure.
[0084] The present application provides a loader including an engine and an exhaust system as described in any of the above embodiments. The engine is connected to an exhaust pipe, and the exhaust pipe is connected to an aftertreatment assembly 100 in the exhaust system.
[0085] The exhaust system has been described in detail in the above embodiments and will not be repeated here.
[0086] It should be noted that the loader also includes existing structures such as the chassis and cab, which are not limited. The engine and exhaust system are both mounted on the chassis. The exhaust pipe can be connected to the aftertreatment assembly 100 by bolting, welding, or other means, so that the aftertreatment assembly 100 can treat the exhaust gases emitted by the engine.
[0087] In summary, the loader provided in this application embodiment, during operation, effectively reduces the possibility of fatigue fracture at the connection between the exhaust pipe 200 and the aftertreatment assembly 100 due to the flexible connection and the support of the support member 300. This solves the problem in the prior art where the connection between the aftertreatment assembly 100 and the exhaust pipe 200 is prone to fatigue fracture after prolonged use, leading to exhaust system failure.
[0088] Finally, it should be noted that other embodiments of this utility model will readily occur to those skilled in the art upon consideration of the specification and practice of the utility model disclosed herein. This utility model is intended to cover any variations, uses, or adaptations of this utility model that follow the general principles of this utility model and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
