Technical Field

[0001] This utility model belongs to the field of commercial vehicle accessories, and in particular relates to a commercial vehicle after-processor mounting component assembly and a commercial vehicle using the assembly. Background Technology

[0002] With the development trend of the commercial vehicle market, and based on users' load-bearing needs, lightweighting of commercial vehicle chassis, without changing the vehicle's total mass limit, frees up more load-bearing space for goods, improving transportation efficiency and economic benefits. At the same time, considering the compactness of the commercial vehicle chassis layout, improving the overall chassis utilization rate and the commonality of chassis layout, the existing after-treatment system mounting component structure is optimized.

[0003] like Figure 1 As shown, the existing commercial vehicle after-processor mounting assembly consists of a heat shield 11, a side heat shield mounting bracket 12, an upper heat shield mounting bracket 13, a shock absorber 14, a supporting square steel pipe beam 15, a clamp-type strap for the after-processor 16, and an after-processor mounting bracket 17.

[0004] like Figure 2 , 3 As shown, the side heat shields 11-1 and the upper heat shield 11-2 of the existing commercial vehicle after-treatment mounting assembly are independent separate components. The after-treatment unit adopts a clamp-type strap 16 mounting structure. In order to pull the overall weight of the after-treatment unit, a reinforced supporting square steel tube beam 15 is provided below the upper heat shield 11-2. Due to the large weight of the after-treatment unit, in order to avoid stress concentration deformation and failure of the clamp-type strap 16 and the upper heat shield mounting bracket 13 due to long-term vehicle vibration, four vibration damping pads 14 are provided between the upper heat shield 11-2 and the clamp. Each side heat shield 11-1 is provided with a side heat shield mounting bracket 12, and the upper heat shield 11-2 is provided with an upper heat shield mounting bracket 13 at the bottom. The front ends of the two supporting square steel tube beams 15 are respectively provided with a frame connection bracket 17.

[0005] Existing commercial vehicle after-treatment system mounting components have numerous parts, complex installation structures, and complicated assembly processes, which are not conducive to the lightweight requirements of commercial vehicle chassis. The component assembly is large in size and occupies a lot of chassis frame layout space, which is not conducive to the installation and layout of related modules, such as gas cylinder frames of different volumes in the gas system, gearbox mounts of different power chains, wiring harnesses inside the frame, pipe bundle supports, etc. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides a commercial vehicle after-treatment system mounting assembly and a commercial vehicle using the assembly, which has a simple manufacturing process, a robust structure, and easy installation.

[0007] This utility model is implemented as follows: a commercial vehicle after-processor mounting assembly includes a heat shield and an after-processor mounting bracket. The heat shield consists of an upper heat shield, two side heat shields, and a front heat shield. The side heat shields on opposite sides of the heat shield are integrally bent with the upper heat shield. A top mounting bracket for connecting to the after-processor is provided on the inner side of the upper heat shield. An upper mounting bracket for connecting to the after-processor is provided on the upper inner side of the side heat shield and the front heat shield. A bottom mounting bracket is provided on the bottom inner side of the side heat shield and the front heat shield. An L-shaped square tube beam bracket is fixed above the bottom mounting bracket. A support bracket for supporting the bottom of the after-processor is installed on the horizontal plane of the square tube beam bracket. A vehicle frame connecting bracket is fixed on the outer side of the vertical plane of the square tube beam bracket.

[0008] The top mounting bracket and upper mounting bracket are welded to the post-processor end and bolted to the heat insulation cover end; the support bracket is welded to the square tube beam bracket end and bolted to the heat insulation cover end.

[0009] The front heat shield is integrally formed with the upper heat shield and the side heat shields on both sides.

[0010] The top mounting bracket adopts a U-shaped bending structure, and the upper mounting bracket adopts a Z-shaped structure.

[0011] A commercial vehicle that uses the aforementioned commercial vehicle after-processor mounting component assembly.

[0012] The advantages and technical effects of this utility model are as follows: Under the condition that the internal carrier unit of the existing after-processor is the same, this utility model changes its packaging shape and installation components, and adopts a square tube beam bracket and a U-shaped bent after-processor mounting bracket, which reduces the weight of the mounting component assembly by 35 kg, and the overall structure is compact, making it suitable for the chassis layout of commercial vehicles.

They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 4-6 As shown, the commercial vehicle after-processor mounting assembly of this utility model includes a heat shield 1 and an after-processor mounting bracket 5. The heat shield 1 is composed of an upper heat shield 1-2, two side heat shields 1-1 on both sides, and a front heat shield 1-3. The side heat shields 1-1 on opposite sides of the heat shield 1 are integrally bent parts with the upper heat shield 1-2. A top mounting bracket 2 connected to the after-processor is provided on the inner side of the upper heat shield 1-2. An upper mounting bracket 8 connected to the after-processor is provided on the upper inner side of the side heat shields 1-1 and the front heat shield 1-3. A bottom mounting bracket 3 is provided on the bottom inner side of the side heat shields 1-1 and the front heat shield 1-3. An L-shaped square tube beam bracket 4 is fixed above the bottom mounting bracket 3. A support bracket 6 for supporting the bottom of the after-processor is installed on the horizontal surface of the square tube beam bracket 4.
