[0038] First Embodiment

[0039] refer to Figures 1 to 7 This application provides a vibration damping and fixing mechanism, including a first sheet metal structure 1, a second sheet metal structure 2, and a pedal assembly 3; the first sheet metal structure 1 and the second sheet metal structure 2 are arranged opposite to each other and installed on the same side of the vehicle chassis. The first sheet metal structure 1 and the second sheet metal structure 2 can provide support for the vehicle chassis and absorb the vibrations generated during vehicle operation, thereby improving operating comfort.

[0040] The first sheet metal structure 1 includes a first mounting part 11 and a first vibration damping part 12; the first mounting part 11 has a first mounting surface 111 parallel to the side of the chassis, and the first mounting surface 111 is matched with the side of the chassis and is provided with a first mounting hole 112 so that the first mounting part 11 is mounted on the side of the chassis; the first vibration damping part 12 is connected to the first mounting part 11, and the first vibration damping part 12 has a first vibration damping surface 121 parallel to the top surface of the chassis, the first vibration damping surface is provided with a first vibration damping hole 122, and a first vibration damping pad is provided inside the first vibration damping hole 122.

[0041] The first mounting surface 111 is parallel to the side of the chassis and can be bolted together to form a surface contact bearing. This evenly distributes the vertical load of the pedal assembly 3 to the side of the chassis, reducing local stress concentration. Simultaneously, the first damping surface 121 is parallel to and higher than the top surface of the chassis, allowing the first damping pad to primarily bear vertical vibrations. When the chassis vibrates vertically due to uneven road surfaces, the damping pad absorbs energy through elastic deformation, effectively absorbing vibrations and improving operational comfort.

[0042] The second sheet metal structure 2 includes a second mounting part 21 and a second vibration damping part 22. The second mounting part 21 has a second mounting surface 211 parallel to the side of the chassis. The second mounting surface 211 is matched with the side of the chassis and is provided with a second mounting hole 212 so that the second mounting part 21 is mounted on the side of the chassis. The second vibration damping part 22 is connected to the second mounting part 21. The second vibration damping part 22 has a second vibration damping surface 221 parallel to and higher than the top surface of the chassis. The second vibration damping surface 221 is provided with a second vibration damping hole 222, and a second vibration damping pad is provided inside the second vibration damping hole 222.

[0043] The second mounting surface 211 is parallel to the side of the chassis and can be bolted together to form a surface contact bearing. This allows the vertical load of the pedal assembly 3 to be evenly distributed to the side of the chassis, reducing local stress concentration. Simultaneously, the second damping surface 221 is parallel to the top surface of the chassis, ensuring that the second damping pad primarily bears vertical vibrations. When the chassis vibrates vertically due to uneven road surfaces, the damping pad absorbs energy through elastic deformation, effectively absorbing vibrations and improving operational comfort.

[0044] The pedal assembly 3 is connected to the first mounting part 11 and the second mounting part 21 respectively. The pedal assembly 3 is mounted on the side of the chassis via the first mounting part 11 and the second mounting part 21, which can provide effective support for the chassis, reduce its own weight while ensuring the strength and rigidity of the components. At the same time, by using vibration damping pads, it can absorb the vibration generated by the vehicle (such as a tractor) during operation and improve the operating comfort.

[0045] In some embodiments, the first sheet metal structure 1 further includes a third mounting portion 13; the third mounting portion 13 is disposed opposite to the first mounting portion 11 and is located at both ends of the first vibration damping portion 12, the third mounting portion 13 has a third mounting surface 131 parallel to the first mounting surface 111, and a third mounting hole 132 corresponding to the first mounting hole 112 is provided on the third mounting surface 131; the axis of the third mounting hole 132 coincides with the axis of the first mounting hole 112, the third mounting hole 132 is used for the sleeve to pass through, and the inner diameter is larger than the outer diameter of the sleeve.

[0046] The vertical length of the third mounting part 13 is greater than that of the first mounting part 11, allowing the first mounting part 11 to be fixedly connected to the side of the chassis. The third mounting part 13 has multiple functional holes, such as third mounting holes 132, fourth mounting holes 133, and welding through holes 134. The number of third mounting holes 132 is the same as the number of first mounting holes 112, and they correspond one-to-one; that is, the axes of the third mounting holes 132 and their corresponding first mounting holes 112 coincide. The inner diameter of the third mounting holes 132 is larger than the outer diameter of the sleeve. When connecting or disassembling the first mounting part 11 to the side of the chassis, the sleeve passes through the third mounting holes 132, and the bolts located in the corresponding first mounting holes 112 are tightened or loosened using the sleeve, thereby improving assembly or disassembly efficiency. Multiple fourth mounting holes 133 are provided, allowing the oil filter to be fixed to the bracket with bolts, solving the problem of inconvenient oil filter installation. This enables the fixing of multiple components within a limited space, improving space utilization.

[0047] In some embodiments, the first sheet metal structure 1 further includes a first reinforcing plate 14, which is connected to the sides of the third mounting portion 13 and the first vibration damping portion 12 respectively; the first reinforcing plate 14 is also provided with a weight reduction hole 141. The first mounting portion 11, the first vibration damping portion 12, the third mounting portion 13 and the first reinforcing plate 14 are integrally formed by welding. The first reinforcing plate 14 can increase the connection strength between the third mounting portion 13 and the first vibration damping portion 12. The side of the first reinforcing plate 14 is formed into a flanged reinforcing rib structure by bending process, and the middle part is cut off to form a weight reduction hole while ensuring strength, thereby reducing material costs and realizing lightweight installation of parts.

[0048] In some embodiments, the second sheet metal structure 2 further includes an oil pump mounting bracket 23 and a first bend 24. The oil pump mounting bracket 23 is used to fix the oil pump, and its two ends are respectively connected to the second mounting portion 21 and the second vibration damping portion 22, thereby strengthening the connection between the second mounting portion 21 and the second vibration damping portion 22. The first bend 24 is arranged side by side with the oil pump mounting bracket 23, and its two ends are respectively connected to the second mounting portion 21 and the second vibration damping portion 22. The oil pump mounting bracket 23, in conjunction with the second bend 24, can further strengthen the connection between the second mounting portion 21 and the second vibration damping portion 22.

[0049] In some embodiments, the second mounting surface 211 is further provided with a pipe clamp fixing hole 213, which is located on one side of the second mounting hole 212 and is used to fix and install a pipe clamp.

[0050] In some embodiments, the first damping hole 122 and the second damping hole 222 are both concentric annular and have bevels at the top, and form a height difference with the first damping surface 121 and the second damping surface 221, respectively. It is not necessary to process the entire upper surface of the first damping surface 121 and the second damping surface 221, but only to process the annular ring to ensure the surface roughness. It can also be adapted to damping pads of different specifications, improving the applicability of the components.

[0051] In some embodiments, the pedal assembly 3 includes: a pedal 31, a second bend 32, and a third bend 33; the pedal 31 is horizontally disposed and located below the second bend 32 and the third bend 33, and is connected to the bottom of the second bend 32 and the third bend 33; the second bend 32 is connected to the first mounting portion 11, the third bend 33 is connected to the second mounting portion 21, and the second bend 32 and the third bend 33 are disposed side by side.

[0052] The second bend 32 and the third bend 33 are formed by bending, replacing the traditional flat plate support, which greatly reduces weight and manufacturing cost. One end of the second bend 32 and the third bend 33 is formed into a flat welding foot 34 by extrusion, which facilitates welding with the pedal. The third mounting surface 131 is provided with a welding through hole 134 for the welding tool to pass through, ensuring that the second bend 32 will not deviate during welding and playing a positioning role.
