Description

Technical Field

[0001] This utility model relates to a key support structure for the intake system of a heavy-duty truck engine, specifically a heavy-duty truck air filter bracket structure. Background Technology

[0002] The technical solutions and development trends of heavy-duty truck air filter brackets mainly revolve around material lightweighting, structural optimization, cost control, and performance improvement. Existing heavy-duty truck air filter brackets are large in size, leading to increased weight and space occupation, affecting the compactness of the engine compartment layout. Furthermore, their complex manufacturing process, increased welding and rust prevention treatments, limited load capacity, and unoptimized vibration characteristics may cause component resonance, accelerating fatigue failure. Utility Model Content

[0003] The purpose of this invention is to achieve an air filter bracket structure that is simple in structure, low in manufacturing cost, and strong in resistance to fatigue damage, while ensuring the structural strength of the air filter bracket.

[0004] This utility model is achieved through the following technical solution: A heavy-duty truck air filter bracket structure includes two bent branch pipes 1 and a Z-shaped support 2. The short sides of the two bent branch pipes 1 are fixedly connected to the inner side of the Z-shaped support 2. The two bent branch pipes 1 are parallel and in the same direction, and are used to connect the air filter.

[0005] The short sides of the two bent branch pipes 1 are connected to the zigzag support 2 with reinforcing ribs 3.

[0006] The reinforcing ribs 3 are connected to the branch pipe 1 and the support 2 by welding.

[0007] There are four bolt holes on the long side of each of the two branch pipes 1 for connecting the air filter, and five bolt holes on the foot side of the Z-shaped support 2 for connecting the air filter bracket and the vehicle frame.

[0008] The two bent branch pipes 1 are made of No. 20 steel, and the Z-shaped support 2 is made of Q345 steel.

[0009] This utility model is constructed by welding and bolting simple sheet metal parts and steel pipe structures, which reduces manufacturing costs. It also has a simple structure, light weight, and is easy to install. Attached Figure Description

[0010] Figure 1 , 2 This is an isometric drawing of this utility model; Figure 3 This is a schematic diagram of the planar structure of this utility model. Detailed Implementation

[0011] like Figure 1-3 As shown, this utility model is a heavy-duty truck air filter bracket structure, including two bent branch pipes 1, a U-shaped support 2, and four reinforcing ribs 3. The short sides of the two bent branch pipes 1 are welded to the U-shaped support 2, and the four reinforcing ribs 3 are welded to the branch pipes 1 and the support 2 respectively. There are four bolt holes on the long sides of the two branch pipes 1 for connecting the air filter, and five bolt holes on the support 2 for connecting the air filter bracket to the vehicle frame.

[0012] In practical use, the four bolt holes on branch pipe 1 are used to connect the air filter, and the five bolt holes on support 2 connect the air filter bracket to the vehicle frame. Reinforcing rib 3 is used to connect branch pipe 1 and support 2, and the connection method is welding.

[0013] The aforementioned stiffening plate 3 not only connects the branch pipe 1 and the support plate seat 2, but also strengthens the structure of the air filter bracket. The branch pipe of the heavy-duty truck air filter bracket is made of No. 20 steel, and the support is made of Q345 steel. CAE analysis shows that the maximum equivalent stress is 68.4 MPa, which meets the strength requirements. The various modes avoid the tire excitation frequency of 5Hz-7Hz and the engine idling frequency of 28Hz-32Hz.

[0014] This invention reduces the vehicle's weight, increases cargo capacity, and reduces fuel consumption while ensuring structural strength. It features a simple and compact structure, facilitating manufacturing and installation. The addition of stiffeners strengthens the structure and enhances its resistance to fatigue failure.
