Description

Technical Field

[0001] This application relates to the field of fuel tank fixing technology, and specifically provides a fuel tank and tractor with a vibration damping fixing device. Background Technology

[0002] Non-road agricultural machinery, especially tractors, has a compact overall structure. Existing designs typically use large mounting brackets for the fuel tank, with large mounting plates on these brackets, secured with cable ties. The fuel tank needs recesses for the cable ties, which then restrict lateral and vertical movement. Additional brackets at the front and rear of the fuel tank further limit its forward and backward movement. This layout is not compact, affects the fuel tank's capacity, and impacts operating time.

[0003] Because agricultural machinery operates under complex conditions and in harsh environments, the engine vibrates significantly. If the bracket that secures the fuel tank is not strong enough, it will resonate with the engine at certain speeds, which can damage the fuel tank over time, causing oil leaks and affecting the overall use of the machine. Utility Model Content

[0011] In a preferred embodiment, a gasket is further provided between the front fixing member and the front damping pad.

[0012] In a preferred embodiment, the bottom surface of the fuel tank body is provided with a planar mounting surface, and the fixing bracket includes a bearing surface. The fixing bracket supports the fuel tank body through the contact between the bearing surface and the mounting surface.

[0013] In a preferred embodiment, a bottom vibration damping pad is provided in the area where the bearing surface of the fixed bracket contacts the mounting surface of the fuel tank body.

[0014] In a preferred embodiment, the fixing bracket further includes a connecting surface, which is perpendicular to the bearing surface; the connecting surface can press the rear vibration damping pad onto the surface of the fuel tank body.

[0037] This application provides a fuel tank with a vibration damping and fixing device, such as... Figures 1 to 5 As shown, it includes a fuel tank body 1, a connecting shaft 4, a first fixed bracket 5, and a second fixed bracket 6.

[0038] Two through holes are provided on the fuel tank body 1, corresponding to the first fixed bracket 5 and the second fixed bracket 6. The rear ends of the two connecting shafts 4 pass through the corresponding through holes, and the front ends of the two connecting shafts 4 remain outside the through holes. A front damping pad 3 and a rear damping pad 8 are respectively fitted on the front and rear ends of each connecting shaft 4. The front damping pad 3 and the rear damping pad 8 support the connecting shaft 4 in the through holes, so that the connecting shaft 4 will not directly contact the hole wall of the through hole.

[0039] The front end of the front damping pad 3 and the front end of the connecting shaft 4 are connected to the fuel tank body 1 by the front fixing member, and the rear end of the rear damping pad 8, the rear end of the connecting shaft 4, and the fuel tank body 1 are connected to the first fixing bracket 5 and the second fixing bracket 6 by the rear fixing member.

[0040] Specifically, the front damping pad 3 and the rear damping pad 8 have a T-shaped longitudinal section, including a cylindrical main body and a flat outer edge at one end of the main body. The main body is sleeved on the connecting shaft 4, and a groove is provided on the surface of the fuel tank body 1 relative to the front damping pad 3, so that the outer edge of the front damping pad 3 can be accommodated in the groove, while the outer edge of the rear damping pad 8 is pressed against the surface of the fuel tank body 1.

[0041] To facilitate the connection between the front and rear fixing parts and the connecting shaft 4, an internal threaded hole is provided at the front end of the connecting shaft 4, and the front fixing part is a bolt 9. Through the engagement of the bolt 9 and the internal threaded hole, the front damping pad 3 and the front end of the connecting shaft 4 are connected to the fuel tank body 1. Under the vibration damping and installation positioning of the damping pad 3, the movement of the fuel tank body 1 along the axial direction of the through hole is restricted, and the center positioning in the circumferential direction can ensure the fixation of the fuel tank body 1.

[0042] To facilitate compaction and uniform force transmission, a shim 2 is also provided between the bolt 9 and the front damping pad 3. The shim 2 is a conventional circular metal structure, mainly used to press the damping pad 3 against the connecting shaft 4 during the tightening process of the connecting parts, so as to ensure reliable bolt tightening.

[0043] A planar mounting surface is provided on the bottom surface of the fuel tank body 1. The first fixed bracket 5 and the second fixed bracket 6 include a bearing surface (e.g., the bearing surface 61 of the second fixed bracket 6). The first fixed bracket 5 and the second fixed bracket 6 contact the mounting surface of the fuel tank body 1 through the bearing surface, so as to realize the bearing of the fuel tank body 1 by the first fixed bracket 5 and the second fixed bracket 6.

[0044] Preferably, a bottom vibration damping pad 11 is attached to the contact area between the bearing surface of the first fixed bracket 5 and the mounting surface of the fuel tank body 1, which can realize vibration damping between the first fixed bracket 5, the second fixed bracket 6 and the fuel tank body 1.

[0045] The first fixed bracket 5 and the second fixed bracket 6 also include a connecting surface (e.g., the connecting surface 62 of the second fixed bracket 6). Taking the second fixed bracket 6 as an example, the connecting surface 62 is perpendicular to the bearing surface 61; the connecting surface 62 can press the rear damping pad 8 onto the surface of the fuel tank body 1. The rear end of the connecting shaft 4 is provided with an external thread section, and the rear fixing member is a nut 10; the external thread section passes through the connecting surface 62, and the rear damping pad 8, the rear end of the connecting shaft, the fuel tank body 1, and the connecting surface 62 of the second fixed bracket 6 are connected through the cooperation of the nut 10 and the external thread section.

[0046] After the first fixed bracket 5 and the second fixed bracket 6 are installed with the fuel tank body 1, the fuel tank body 1, the first fixed bracket 5 and the second fixed bracket 6 can be used as a whole, which is convenient for assembly and saves the assembly time of the whole machine.

[0047] Preferably, the front damping pad 3, the rear damping pad 8, and the bottom damping pad 11 are all made of rubber.

[0048] In other embodiments, more mounting brackets can be provided, such as three or four, depending on the volume of the fuel tank.

[0049] This application embodiment also provides a tractor, including the fuel tank with vibration damping and fixing device and the whole machine fixing frame 7; the fuel tank body 1 is fixedly connected to the whole machine fixing frame 7 through the first fixing bracket 5 and the second fixing bracket 6.

[0050] During installation, front damping pads 3 and rear damping pads 8 are installed at both ends of the through hole of the fuel tank body 1, respectively. The rear end of the connecting shaft 4 is installed on the first fixed bracket 5 and the second fixed bracket 6, respectively. The first fixed bracket 5 and the second fixed bracket 6 with the connecting shaft 4 installed are passed through the middle hole of the damping pad 3. After the shim 2 is installed, the shim 2 is fixed to the internal thread hole at the front end of the connecting shaft 4 with the bolt 9. The shim 2 compresses the damping pad 3 under the action of the axial force of the bolt 9 and finally sticks to the connecting shaft 4. After tightening, the installation of the fuel tank body 1 with the first fixed bracket 5 and the second fixed bracket 6 is completed. Then, the fuel tank body 1, the first fixed bracket 5 and the second fixed bracket 6 are installed together on the whole machine fixing frame 7, and the assembly of the fuel tank body 1 is completed.

[0051] The fuel tank body achieves thorough vibration reduction through vibration damping pads, connecting shafts, fixed brackets, and the overall machine mounting frame, thus ensuring the fuel tank's reliability and improving product quality. Furthermore, the installation structure is convenient, saving installation time and improving work efficiency. The mounting bracket base plate has bottom vibration damping pads, which also support the lower part of the fuel tank body, reducing the weight of the fuel tank on the connecting shaft and vibration damping pads, further enhancing product reliability. It also facilitates the fixing of the fuel tank sub-assembly to the main machine, saving assembly time and improving fuel tank reliability. Additionally, it ensures maximum space arrangement for the fuel tank, maximizing its volume to guarantee the machine's operating time.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
