Description

Technical Field

[0001] This utility model belongs to the field of truck exhaust pipe technology, and specifically relates to a truck exhaust pipe device. Background Technology

[0002] As heavy-duty transportation vehicles, the performance of a truck's engine exhaust system directly affects the vehicle's power, economy, and environmental performance. Modern truck exhaust pipes often have a multi-section structure, with different sections serving different functions, such as noise reduction and exhaust gas treatment. However, most common truck exhaust pipes are integrated structures fixed to the truck chassis. As a consumable and non-permanent component, the exhaust pipe is prone to damage during use, requiring regular inspection or replacement. The integrated design of the exhaust pipe may prevent partial replacement, increasing replacement costs and difficulty. Furthermore, exhaust gas filters also require regular replacement; inconvenient filter removal and installation may result in infrequent replacements, leading to poor exhaust gas treatment and impacting truck performance. Therefore, the structure securing the exhaust pipe also needs to have a convenient disassembly and assembly mechanism; otherwise, inspection and replacement will be difficult.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

[0037] Please see Figures 1-5 and Figure 6 As the first embodiment of this utility model:

The ash seat flange 203 and the ash outlet sealing seat 700 are attached to each other and fixed by bolts. The ash outlet sealing seat 700 is placed under the ash seat flange 203 and installed in close contact. The sealing ring groove 204 of the sealing seat and the sealing ring are fitted together to achieve a sealing connection. During use, the lower part of the ash seat 202 is sealed to prevent ash from being discharged.

[0043] The filter element holder 206 is fixedly installed at the lower right end of the exhaust gas treatment pipe 201.

The support component 300 is pre-installed under the truck chassis, so that the two sets of clamping semi-rings 306 are symmetrically placed on the outside of the pipe to clamp the pipe. After the two sets of mating plates 307 are attached, they are fixed by bolts, which facilitates the disassembly and assembly of different sections of the pipe.

[0047] The inner side of the muffler 101 is fixedly connected to a micro-perforated plate 104 for providing noise reduction. Both the muffler 101 and the exhaust gas treatment pipe 201 are made of stainless steel layer 101a, ceramic layer 101b and outer wear-resistant layer 101c.

They are also connected to other pipe sections using the same structure. The installation of different pipe sections is assisted by a metal corrugated pipe 103. The silencer pipe 101 and exhaust gas treatment pipe 201, which are made of stainless steel layer 101a, ceramic layer 101b and outer wear-resistant layer 101c, improve the service life of the pipes. The noise reduction effect of the silencer pipe 101 is improved by a micro-perforated plate 104.

During the clamping and fixing of the pipe fitting, the clamping half rings 306 directly contact the pipe fitting through the rubber pads 308, which improves the flexible and slow-release clamping. The vibration generated during the truck's operation can also be slowed down by the damping shock absorber 302.

[0050] Additionally, the ash outlet seal 700 is placed below the ash seat flange 203 for close mounting, and the sealing connection is achieved through the sealing ring groove 204 of the seal and the sealing ring. During use, the bottom of the ash seat 202 is sealed to prevent ash from being discharged, and the filter element 500 is movably fitted into the filter element groove 207, and the filter element fixing seat 600 is placed below the filter element 500 to support and install with the filter element seat 206, thereby facilitating the disassembly and assembly of the filter element 500, thus achieving the effect of independent and convenient disassembly and assembly.

[0051] Please see Figures 1-2 , Figures 5-6 and Figure 8 As a second embodiment of this utility model:

[0052] The inner side of the exhaust gas treatment pipe 201 is provided with a collection groove 205 located to the lower left of the filter element seat 206, which converges towards the center of the ash seat 202.

[0053] The collection trough 205 is connected to the upper opening of the ash seat 202. A knocking component 400 is also fixedly installed below the mounting plate 301 of the right end support component 300. The knocking component 400 includes a knocking cylinder 401 and a knocking seat 402. The knocking seat 402 is fixedly connected below the knocking cylinder 401. During use, the knocking cylinder 401 is activated intermittently to drive the knocking seat 402 to knock on the exhaust gas treatment pipe 201, causing the dust adhering to its inner wall to fall into the collection trough 205 and then be collected in the ash seat 202. The dust is then discharged by disassembling the ash outlet seal 700 later.

[0054] Based on the first embodiment described above, further, the dust adhering to the inner wall of the exhaust gas treatment pipe 201 is activated intermittently during use, and the striking cylinder 401 drives the striking seat 402 to strike the exhaust gas treatment pipe 201, causing the dust adhering to the inner wall to fall into the collecting groove 205, and then collect in the dust seat 202. The dust can be discharged by disassembling the dust outlet seal 700 later, thereby assisting in the dust discharge.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
