[0002] During operation, machinery such as loaders, excavators, and road rollers generate a large amount of heat from their engines and other components. This accumulated heat can lead to high temperatures and equipment malfunctions. To ensure the normal and stable operation of the equipment, these machines need to be equipped with radiators to cool them quickly and effectively.

[0003] Radiators on construction machinery typically consist of a core and a frame. Traditionally, the radiator core is rigidly connected to the frame. This connection structure can allow vibrations from the machinery to be directly transmitted to the radiator core, making it prone to leakage under prolonged vibration and affecting the radiator's lifespan.

[0004] A vibration damping mechanism has been proposed to be added between the radiator core and the frame. For example, mounting holes are provided at corresponding positions on two opposite sides of the radiator core, and fasteners pass through through holes in the two side plates of the frame and connect to the mounting holes on the radiator core to fix the vibration damper between the frame and the radiator core on both sides. This concentrically arranged vibration damper has the problem of difficult installation. Summary of the Invention

[0006] To achieve the above objectives, according to one aspect of the present invention, a vibration-damping connection structure is provided for connecting a radiator core to a frame. The frame includes a first side plate and a second side plate disposed opposite each other in a transverse direction. The first side plate and the second side plate are respectively provided with a first through hole and a second through hole opposite each other in the transverse direction. The vibration-damping connection structure includes a first vibration-damping component disposed at the first through hole and a second vibration-damping component disposed at the second through hole. The first vibration-damping component includes a first vibration-damping pad, and the second vibration-damping component includes a second vibration-damping pad. The second vibration-damping component includes an adapter plate, which covers the second through hole on the outer side of the first side plate and has an adapter hole. The maximum outer diameter of the second vibration-damping pad is larger than the diameter of the adapter hole and smaller than the diameter of the second through hole.

[0007] According to one embodiment of the present invention, the second damping pad includes an annular body portion and an axially extending portion extending radially outward from the radially inner end of the annular body portion. The axially extending portion has a first outer diameter.

[0011] According to one embodiment of the present invention, the adapter plate is further provided with mounting holes, and mounting bolts pass through the mounting holes to fix the adapter plate to the outside of the second side plate.

[0012] According to one embodiment of the present invention, the first shock-absorbing component further includes a first steel sleeve, and the first shock-absorbing pad is sleeved on the first steel sleeve; the second shock-absorbing component further includes a second steel sleeve, and the second shock-absorbing pad is sleeved on the second steel sleeve.

[0013] According to one embodiment of the present invention, the first damping assembly further includes a third damping pad disposed on the axial outer side of the first side plate, and the second damping assembly further includes a fourth damping pad disposed on the axial outer side of the adapter plate.

[0014] According to one embodiment of the present invention, the third damping pad and the first damping pad are separate structures or integrally formed, and the fourth damping pad and the fourth damping pad are separate structures or integrally formed.

[0015] According to one embodiment of the present invention, the first shock-absorbing assembly further includes a first bolt for fixing the first shock-absorbing pad to the radiator core, and the second shock-absorbing assembly further includes a second bolt for fixing the second shock-absorbing pad to the radiator core, the second bolt passing through the adapter hole on the adapter plate.

[0016] According to one embodiment of the present invention, the first shock-absorbing assembly includes another adapter plate, the other adapter plate covering the first through hole on the outside of the first side plate and having another adapter hole, wherein the maximum outer diameter of the first shock-absorbing pad is greater than the diameter of the other adapter hole and smaller than the diameter of the first through hole.

[0028] The terms "first" and "second" are used below to describe the elements of this application. These terms are used only to distinguish the individual elements and not to limit the nature, order, or number of these elements. The terms "comprising" and "having" are used to indicate an open-ended inclusion and mean that there may be additional elements / components besides those listed.

[0029] Figure 1 A heat sink assembly according to an embodiment of the present invention is shown. Figures 2 to 4 The shock-absorbing connection structure for connecting the radiator core 1 to the frame 2 in this embodiment is shown.

[0030] like Figure 1 As shown, the radiator core 1 in this embodiment is generally rectangular. The radiator core 1 has internal channels for coolant flow. The radiator is preferably a water-cooled radiator. The frame 2 surrounds the outer periphery of the radiator core 1, and its shape is adapted to the shape of the radiator core 1. In this embodiment, the space enclosed by the frame 2 is larger than the radiator core 1, and this space can also accommodate other components, such as an intercooler or an oil cooler.

[0031] The heat sink assembly may include multiple vibration-damping connection structures. For example, in Figure 1 In the embodiment shown, four shock-absorbing connection structures are spaced apart on the upper and lower sides of the frame 2, and the radiator core 1 can be connected to the frame 2 at its four corners through the shock-absorbing connection structures.

[0032] Figure 2 It shows Figure 1 A cross-sectional view of the damping connection structure in the lower left corner along line AA. (See image.) Figure 2As shown, the frame 2 may include a first side plate 21, a second side plate 22, and a connecting plate connecting the bottom of the first side plate 21 and the bottom of the second side plate 22, which are arranged opposite each other in the lateral direction. It is understood that for the frame 2 above the radiator core 1, the connecting plate may be located on the upper side. The first side plate 21, the second side plate 22, and the connecting plate are preferably integrally formed, defining a generally U-shaped cavity into which the peripheral portion of the radiator core 1 can be embedded for support. The first side plate 21 is provided with a first through hole 23, and the second side plate 22 is provided with a second through hole 24 opposite to the first through hole 23 in the lateral direction.

[0033] In this article, "lateral direction" refers to the direction in which the first side plate 21 and the second side plate 22 are arranged opposite each other. The following will be based on... Figure 2 The positional relationship of the first side plate 21 on the left and the second side plate 22 on the right shown is described.

[0034] The shock-absorbing connection structure in this embodiment may include a first shock-absorbing component 3 disposed at the first through hole 23 and a second shock-absorbing component 4 disposed at the second through hole 24.

[0035] Figure 3 Show Figure 2 An enlarged view of point B as indicated in the diagram. (See diagram below.) Figure 2 and Figure 3 As shown, the first damping component 3 may include a first steel sleeve 31, a first damping pad 32, a first bolt 33, a first washer 34, and a third damping pad 35.

[0036] The first steel sleeve 31 may include an axially extending cylindrical portion and a flange portion extending radially outward from the axially inner end of the cylindrical portion. In this text, "axial" refers to the transverse direction along the radiator core 1, "axially inner" refers to the side axially closer to the radiator core 1, and "axially outer" refers to the side axially away from the radiator core 1. The flange portion of the first steel sleeve 31 may abut against the left side of the radiator core 1, and its outer diameter may be larger than the outer diameter of the first through hole 23, thus having a corresponding overlap between the flange portion and the first side plate 21. The outer diameter of the cylindrical portion of the first steel sleeve 31 may be slightly smaller than the diameter of the first through hole 23, so that the cylindrical portion can pass through the first through hole 23 and extend beyond the first side plate 21.

[0037] The first damping pad 32 may include an annular main body and an axial extension extending radially outward from the radially inner end of the annular main body. The axial extension has a first outer diameter, and the annular main body has a second outer diameter larger than the first outer diameter. The first damping pad 32 can be fitted onto a first steel sleeve 31. The flange portion of the first steel sleeve 31 and the second outer diameter of the annular main body of the first damping pad 32 may be substantially equal. The axial extension of the first damping pad 32 and the cylindrical portion of the first steel sleeve 31 can pass through a first through hole 23. The extension length of the axial extension of the first damping pad 32 may be equal to the thickness of the first side plate 21. The second outer diameter of the annular main body of the first damping pad 32 is larger than the diameter of the first through hole 23, such that the annular main body can abut against the axially inner surface of the first side plate 21 between the flange portion of the first steel sleeve 31 and the first side plate 21.

[0038] The third damping pad 35 is fitted onto the cylindrical portion of the first steel sleeve 31 on the axially outer side of the first side plate 21 and abuts against the axially outer side of the first side plate 21, i.e., the left side surface away from the radiator core 1. The first gasket 34 abuts against the third damping pad 35 to clamp the third damping pad 35 between the first gasket 34 and the first side plate 21. The first bolt 33 passes through the hollow portions of the first gasket 34 and the first steel sleeve 31 in sequence and is threaded into the mounting portion of the radiator core 1, thereby fixing the radiator core 1 to the first side plate 21.

[0039] The first damping pad 32 and the third damping pad 35 can work together to achieve damping between the first side plate 21 and the radiator core 1 in the axial and radial directions.

[0040] Figure 4 Show Figure 2 A magnified view of point C, as indicated in the diagram. Figure 2 and Figure 4 As shown, the second damping assembly 4 may include a second steel sleeve 41, a second damping pad 42, a second bolt 43, a second washer 44, a fourth damping pad 45, and an adapter plate 46.

[0041] In this embodiment, the second steel sleeve 41, the second damping pad 42, the second bolt 43, the second washer 44, and the fourth damping pad 45 are respectively connected to... Figure 3 The first steel sleeve 31, the first shock-absorbing pad 32, the first bolt 33, the first washer 34, and the third shock-absorbing pad 35 shown have basically the same structure and function, and will not be described in detail here.

[0042] The second damping component 4 differs from the first damping component 3 primarily in that it also includes a transition plate 46. The shape of the transition plate 46 is not particularly limited. The thickness of the transition plate 46 is substantially equal to the axial extension length of the second damping pad 42. In this embodiment, the thickness of the transition plate 46 is substantially equal to the thickness of the second side plate 22. In other embodiments, the thickness of the transition plate 46 and the axial extension length of the second damping pad 42 may be greater than or less than the thickness of the second side plate 22.

[0043] An adapter hole 461 is provided in the middle of the adapter plate 46. The diameter of the adapter hole 461 is smaller than the maximum outer diameter of the second damping pad 42. In this embodiment, the maximum outer diameter of the second damping pad 42 is the second outer diameter of the annular main body of the second damping pad 42, while the diameter of the adapter hole 461 is basically equal to the first outer diameter of the axial extension of the second damping pad 42.

[0044] The diameter of the second through hole 24 on the second side plate 22 is larger than the maximum outer diameter of the second shock-absorbing pad 42. In this embodiment, the diameter of the second through hole 24 is larger than the diameter of the first through hole 23, while the diameter of the adapter hole 461 can be approximately equal to the diameter of the first through hole 23.

[0045] The cylindrical portion of the second steel sleeve 41 and the axial extension of the second damping pad 42 can pass through the adapter hole 461. The annular body portion of the second damping pad 42 and the flange portion of the second steel sleeve 41 can be clamped between the radiator core 1 and the adapter plate 46. The fourth damping pad 45 is clamped between the second pad 44 and the adapter plate 46.

[0046] The adapter plate 46 may be provided with mounting holes (not shown). The mounting bolts 5 may pass through the gasket 6 and the mounting holes on the adapter plate 46 to fix the adapter plate 46 to the axial outer side of the second side plate 22.

[0047] It should be understood that Figure 1 The side shown is the side where the second side plate 22 of the frame 2 is located. The second damping components 4 of the four damping connection structures are all located on this side, which facilitates the connection of the radiator core 1 to the first side plate 21 first through the first damping component 3, and then to the second side plate 22 through the second damping component 4.

[0048] The present invention also provides a working machine including the above-described radiator assembly.

[0049] Industrial applicability

[0050] The shock-absorbing connection structure according to the invention is particularly suitable for radiator assemblies of working machinery. However, it should be understood that the shock-absorbing connection structure according to the invention can also be used for other equipment that requires the installation of radiator assemblies.

[0051] The following is combined Figures 1 to 4 The illustrated embodiment describes the assembly process of connecting the radiator core 1 to the frame 2 using a vibration-damping connection structure. In this assembly process, firstly, one side of the radiator core 1 is fixed to the first side plate 21 of the frame 2 using multiple first vibration-damping components 3, and then the other side of the radiator core 1 is fixed to the second side plate 22 of the frame 2 using multiple second vibration-damping components 4. The following description primarily uses one set of first vibration-damping components 3 and second vibration-damping components 4 as an example.

[0052] First, the radiator core 1 is positioned as close as possible to the second side plate 22 located on the right side of the figure. In the illustrated embodiment, the radiator core 1 has a columnar structure on its right side for mounting the second damping pad 42. The outer diameter of this columnar structure is smaller than the diameter of the second through hole 24, allowing a portion of the columnar structure to extend into the second through hole 24. This better ensures that the distance between the left side of the radiator core 1 and the first side plate 21 is sufficient to accommodate the first steel sleeve 31 and the first damping pad 32.

[0053] Then, the first damping pad 32 is fitted onto the outer periphery of the first steel sleeve 31, so that the annular main body of the first damping pad 32 abuts against the flange of the first steel sleeve 31. The first steel sleeve 31 and the first damping pad 32 are placed between the first side plate 21 and the radiator core 1. The radiator core 1 is moved laterally to the left to push the cylindrical part of the first steel sleeve 31 and the axial extension of the first damping pad 32 into the first through hole 23 until the annular main body of the first damping pad 32 abuts against the axial inner surface of the first side plate 21.

[0054] Next, the third damping pad 35 is fitted onto the cylindrical portion of the first steel sleeve 31 extending out of the first side plate 21 from the outside of the first side plate 21. The first bolt 33 is threaded through the first washer 34 and the first steel sleeve 31 from the outside of the first side plate 21 and then threaded onto the mounting portion of the radiator core 1. Thus, the radiator core 1 is fixed to the first side plate 21 of the frame 2 via the first damping assembly 3.

[0055] After fixing the left side of the radiator core 1 to the first side plate 21 of the frame 2, the second damping pad 42 is fitted onto the second steel sleeve 41, such that the annular main body of the second damping pad 42 abuts against the flange of the second steel sleeve 41. The second steel sleeve 41 and the second damping pad 42 are then inserted through the second through hole 24 from the outside of the second side plate 22.

[0056] Then, the adapter plate 46 is fitted onto the axial extension of the second damping pad 42 on the outside of the second side plate 22. The mounting bolts 5 are then passed through the mounting holes of the third washer 6 and the adapter plate 46 in sequence to fix the adapter plate 46 to the second side plate 22.

[0057] Next, the fourth damping pad 45 is fitted onto the cylindrical part of the second steel sleeve 41 that extends out of the adapter plate 46. The second bolt 43 is then threaded through the second washer 44 and the second steel sleeve 41 and connected to the mounting part of the radiator core 1. Thus, the radiator core 1 is fixed to the second side plate 22 of the frame 2 by the second damping assembly 4.

[0058] As described above, the shock-absorbing connection structure of the illustrated embodiment includes an adapter plate 46, which covers the second through hole 24 on the outside of the second side plate 22 and has an adapter hole 461. The maximum outer diameter of the second shock-absorbing pad 42 is larger than the diameter of the adapter hole 461 and smaller than the diameter of the second through hole 24. Thus, after the left side of the radiator core 1 is fixed to the first side plate 21 of the frame 2 by the first shock-absorbing assembly 3, the second shock-absorbing pad 42 can be easily pushed into the internal space of the frame 2 from the outside of the second side plate 22 through the larger diameter second through hole 24 and then fixed to the radiator core 1.

[0059] In existing concentrically arranged shock absorbers, the structures on both sides are identical. The maximum outer diameter of the damping pad is larger than the diameter of the through hole on the frame side plate. During assembly, the damping pad needs to be compressed and deformed before passing through the smaller diameter through hole on the frame side plate and being inserted into the inside of the frame. The larger diameter portion of the damping pad then returns to its original shape after passing through the through hole and rests against the inner surface of the frame. This installation process is time-consuming and labor-intensive. The shock-absorbing connection structure of this invention solves the problem of difficult assembly of concentrically arranged shock absorbers by making the diameter of the through hole on one side of the frame larger than the maximum outer diameter of the damping pad on that side and adding a transition plate on that side, thus improving the assembly efficiency of the radiator assembly.

[0060] In the illustrated embodiment, the third damping pad 35 and the first damping pad 32 are separate structures, as are the fourth damping pad 45 and the second damping pad 42. However, this invention is not limited to this. In another embodiment, the third damping pad 35 can be integrally formed with the first damping pad 32, and the fourth damping pad 45 can be integrally formed with the second damping pad 42. In the case of integral forming, the damping pad initially has a T-shaped cross-section, like the first damping pad 32 and the second damping pad 42, except that the length of the axial extension is longer. This axial extension is bent at approximately 90 degrees after passing through the through hole in the frame side plate or transition plate, thereby abutting against the axial outer side of the frame side plate or transition plate, so that the damping pad has a generally I-shaped cross-section. It should be understood that the first pad 34 and the second pad 44 are designed to ensure that the outer portion of the damping pad can be pressed against the frame side plate or transition plate.

[0061] The illustrated embodiment has an adapter plate on only one side of the frame; however, the invention is not limited to this. In another embodiment, the first damping assembly 3 may also include another adapter plate similar to the adapter plate 46, which covers the first through hole 23 on the outside of the first side plate 21 and has another fitting hole. The maximum outer diameter of the first damping pad 32 is larger than the diameter of the other fitting hole but smaller than the diameter of the first through hole 23. Thus, both damping pads can be easily inserted from the outside of the corresponding side plates and fixed by means of the adapter plate.

[0062] Various modifications and variations can be made to the embodiments disclosed above without departing from the scope or spirit of the invention. Other embodiments of the invention will be apparent to those skilled in the art based on the practice of the invention disclosed in this specification. This specification and the examples disclosed herein should be considered illustrative only, and the true scope of the invention is defined by the appended claims and their equivalents.
