Specific Embodiments

[0031] The following will describe in detail the specific embodiments of the present application with reference to the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0032] The following describes the noun parts of the radiator mounting structure and construction machinery according to the present application with reference to the accompanying drawings.

[0033] As Figure 1 and Figure 2 shown, a specific embodiment of the present application provides a radiator mounting structure, including a mounting assembly 3 and a limiting assembly 4. Among them, the mounting assembly 3 is used to mount the radiator 1 on the front hood assembly 2 and includes a mating mounting seat 31 and a mounting base 32. One of the mounting seat 31 and the mounting base 32 is connected to the radiator 1, and the other is connected to the front hood assembly 2. The mounting seat 31 and the mounting base 32 can form a radial clearance and an axial clearance. A radial damping member is filled between the radial clearances, and an axial damping member is filled between the axial clearances; the limiting assembly 4 is arranged between the radiator 1 and the front hood assembly 2 to limit the radiator 1.

[0034] Construction machinery is used for various engineering construction operations. The construction machinery includes a variety of internal devices and a radiator 1 for cooling the internal devices. The radiator 1 is mounted on the front hood assembly 2 equivalent to a frame structure. During the construction operation, the construction machinery will generate vibrations, and the vibrations will be transmitted to the radiator 1 through the front hood assembly 2. Once the vibrations are too large, it may cause the radiator 1 to deform. In the present application, the radiator 1 and the front hood assembly 2 are connected by the mounting assembly 3 and the limiting assembly 4. The relative displacement generated by the vibrations between the radiator 1 and the front hood assembly 2 is reduced by the limiting assembly 4, and the vibrations are weakened by the radial damping member and the axial damping member with damping effects, so as to reduce the influence of the vibrations of the construction machinery on the radiator 1, and further extend the service life of the radiator 1.

[0035] In other words, the mounting assembly 3 plays a supporting role, and the limiting assembly 4 plays a limiting role. Moreover, the radial damping member and the axial damping member can weaken the vibrations in all directions. It can be seen that the mounting structure of the present application can weaken the vibrations received by the radiator 1 in all directions to minimize the influence of the vibrations of the construction machinery on the radiator 1.

[0036] It should be noted that in the present application, unless otherwise stated, the "front-back direction", "left-right direction", and "up-down direction" used are the directions shown by the arrows in the figure respectively.

[0037] Those skilled in the art can understand that the mounting component 3 and the limiting component 4 can be arranged on the left side, right side, upper side or lower side of the radiator 1. The mounting component 3 and the limiting component 4 can be arranged on the same side or different sides of the radiator 1, and the specific positions can be set arbitrarily according to actual needs. Multiple mounting components 3 and multiple limiting components 4 can also be provided to strengthen the connection between the radiator 1 and the front cover assembly 2 and improve the vibration attenuation effect.

[0038] In the exemplary embodiment of the present application, the number of both the mounting component 3 and the limiting component 4 is two. Among them, one mounting component 3 and one limiting component 4 are arranged on the left side of the radiator 1, and the other mounting component 3 and the other limiting component 4 are arranged on the right side of the radiator 1. The mounting component 3 is arranged above the limiting component 4 on the same side. The mounting component 3 on the left side and the limiting component 4 on the left side will be described in detail below. The structure of the mounting component 3 on the right side is the same as that of the mounting component 3 on the left side, and the structure of the limiting component 4 on the right side is the same as that of the limiting component 4 on the left side, and will not be elaborated.

[0039] In some embodiments, the mounting support 31 includes a first sleeve portion and a first connection portion connected to the axial end of the first sleeve portion. The mounting base 32 includes a first pin portion and a first chassis portion provided at the axial end of the first pin portion. Among them, the first connection portion is connected to the front cover assembly 2, the first chassis portion is connected to the radiator 1, the first connection portion, the axial shock absorber and the first chassis portion are arranged in sequence along the axis, and the first sleeve portion, the radial shock absorber and the first pin portion are nested in sequence.

[0040] Specifically, both the first sleeve portion and the first pin portion extend in the left-right direction, that is, the axis of the first sleeve portion and the axis of the first pin portion are both in the left-right direction. The first connection portion is connected to the left end of the first sleeve portion and is connected to the front cover assembly 2. The first chassis portion is connected to the right end of the first pin portion and is connected to the radiator 1. The first sleeve portion is hollow, the first pin portion is inserted and matched with the first sleeve portion, a radial gap is formed between the outer peripheral wall of the first pin portion and the inner peripheral wall of the first sleeve portion, and an axial gap is formed between the right end of the first sleeve portion and the left end of the first chassis portion.

[0041] Furthermore, the radial shock absorber is embedded in and fills the radial gap. In other words, the outer peripheral wall of the radial shock absorber is in close contact with the inner peripheral wall of the first sleeve portion, and the inner peripheral wall of the radial shock absorber is in close contact with the outer peripheral wall of the first pin portion. It can be seen that the radial shock absorber can give full play to its shock-absorbing effect to weaken the vibration transmitted from the first sleeve portion to the first pin portion; the axial shock absorber is embedded in and fills the axial gap. In other words, the left end portion of the axial shock absorber is in close contact with the right end portion of the first sleeve portion, and the right end portion of the axial shock absorber is in close contact with the left end portion of the first chassis portion. It can be seen that the axial shock absorber can give full play to its shock-absorbing effect to weaken the vibration of the first sleeve portion on the first chassis portion.

[0042] Since the first connecting portion is connected to the front cover assembly 2 and the first chassis portion is connected to the radiator 1, the vibration generated by the construction machinery will be transmitted from the front cover assembly 2 to the radiator 1 through the first connecting portion, the first sleeve portion, the first pin portion, and the first chassis portion. During the vibration transmission process, the radial shock absorber disposed in the radial gap can weaken the vibrations in all directions in the plane where the front-rear direction and the up-down direction are located, and the axial shock absorber disposed in the axial gap can weaken the vibration in the left-right direction, so as to achieve an all-round weakening of the vibration effect, and further make the radiator mounting structure achieve the best shock-absorbing effect.

[0043] Preferably, the radial shock absorber is disposed at the axial end of the axial shock absorber. The radial shock absorber and the axial shock absorber are integrally formed into a shock-absorbing bushing 33. Integrally forming the radial shock absorber and the axial shock absorber can effectively reduce the number of components of the radiator mounting structure. At the same time, the integrally formed radial shock absorber and axial shock absorber have a better shock-absorbing effect.

[0044] Preferably, the shock-absorbing bushing 33 is a prefabricated component and includes a first rigid sleeve, a first elastic sleeve, and a second rigid sleeve nested in sequence. The first rigid sleeve is connected to the mounting support 31, and the second rigid sleeve is connected to the mounting base 32. Since the first elastic sleeve is a flexible component and is inconvenient to assemble, if the first elastic sleeve is directly sleeved on the first pin portion and then inserted into the first sleeve portion, it will cause problems in assembly. Therefore, setting the first rigid sleeve, the first elastic sleeve, and the second rigid sleeve to be prefabricated into the shock-absorbing bushing 33 and then assembled can greatly reduce the assembly difficulty.

[0045] Furthermore, the first sleeve portion, the first rigid sleeve, the first elastic sleeve, the second rigid sleeve, and the first pin portion are nested in sequence, and optimally coaxially arranged, which can further reduce the production and assembly difficulty.

[0046] In some embodiments, the limiting assembly 4 includes a limiting support 41, an annular shock absorber, and a limiting base 42 nested in sequence, wherein the limiting support 41 is used for connecting to the front cover assembly 2, and the limiting base 42 is connected to the radiator 1.

[0047] Specifically, the limit support 41 includes a second sleeve portion and a second connecting portion provided on the radial side portion of the second sleeve portion, and the limit base 42 includes a second pin portion and a second chassis portion provided at the axial end of the second pin portion. Among them, the second connecting portion is connected to the front cover assembly 2, the second chassis portion is connected to the radiator 1, and the second sleeve portion, the annular shock absorber, and the second pin portion are nested in sequence.

[0048] Both the second sleeve portion and the second pin portion extend in the left-right direction, that is, the axial directions of both the second sleeve portion and the second pin portion are the left-right direction. The second sleeve portion is hollow, the second pin portion is inserted and matched with the second sleeve portion, and an annular shock absorber is embedded between the outer peripheral wall of the second pin portion and the inner peripheral wall of the second sleeve portion to fill the gap between the second pin portion and the second sleeve portion. In other words, the outer peripheral wall of the annular shock absorber is closely attached to the inner peripheral wall of the second sleeve portion, and the inner peripheral wall of the annular shock absorber is closely attached to the outer peripheral wall of the second pin portion. It can be seen that the annular shock absorber can fully exert its shock-absorbing effect to weaken the vibration of the second sleeve portion on the second pin portion.

[0049] Furthermore, the second connecting portion is connected to the front end portion of the second sleeve portion and is connected to the front cover assembly 2, and the second chassis portion is connected to the right end portion of the second pin portion and is connected to the radiator 1. That is, the second connecting portion, the second sleeve portion, the second pin portion, and the second chassis portion mainly play a limiting role on the radiator 1 in all directions within the plane of the front-rear direction and the up-down direction.

[0050] Even though the limit assembly 4 can play a limiting role on the radiator 1, during the construction operation of the construction machinery, relative movement in all directions within the plane of the front-rear direction and the up-down direction will still occur between the radiator 1 and the front cover assembly 2. During the vibration of the front cover assembly 2, the annular shock absorber provided between the second sleeve portion and the second pin portion can further weaken the vibration in all directions within the plane of the front-rear direction and the up-down direction, thereby enhancing the shock-absorbing effect of the radiator installation structure and further reducing the vibration of the radiator 1.

[0051] Such as Figure 3As shown, preferably, the limiting support 41 is integrally formed with the annular shock-absorbing member. Integrally forming the limiting support 41 and the annular shock-absorbing member can effectively reduce the number of components of the radiator mounting structure. The annular shock-absorbing member includes a third rigid sleeve 44 and a second elastic sleeve 43. The second sleeve portion of the limiting support 41, the second elastic sleeve 43, and the third rigid sleeve 44 are nested in sequence. The third rigid sleeve 44 is connected to the second pin portion in an inserted manner. Since the second elastic sleeve 43 is a flexible member and is inconvenient to assemble, if the second elastic sleeve 43 is directly sleeved on the second pin portion and then inserted into the second sleeve portion, it will cause problems in assembly. Therefore, setting the second sleeve portion, the second elastic sleeve 43, and the third rigid sleeve 44 to be prefabricated and then assembled can greatly reduce the assembly difficulty.

[0052] Furthermore, the second sleeve portion, the second elastic sleeve 43, the third rigid sleeve 44, and the second pin portion are nested in sequence, and preferably coaxially arranged, which can further reduce the production and assembly difficulty.

[0053] Those skilled in the art can understand that the first rigid sleeve, the second rigid sleeve, and the third rigid sleeve 44 can be made of rigid and wear-resistant materials such as metal parts and hard plastic parts, and the first elastic sleeve and the second elastic sleeve 43 can be made of elastic and wear-resistant materials such as rubber parts and silicone parts.

[0054] Preferably, the limiting component 4 further includes a pressing plate member 45. The second chassis portion and the pressing plate member 45 are respectively arranged at two axial ends of the second sleeve portion, that is, the pressing plate member 45 is arranged at the left end of the second sleeve portion. The pressing plate member 45 covers the left end of the second sleeve portion and is fixed to the second sleeve portion by fasteners to prevent the second elastic sleeve 43 from separating from the second sleeve portion in the left-right direction.

[0055] In some embodiments, the mounting base 32 is welded to the radiator 1, the limiting base 42 is welded to the radiator 1, the mounting support 31 is fixedly connected to the front cover assembly 2, and the limiting support 41 is fixedly connected to the front cover assembly 2.

[0056] Specifically, a plurality of connection holes are formed on the first connection portion of the mounting support 31 and the second connection portion of the limiting support 41. Correspondingly, a plurality of fixing holes are formed on the front cover assembly 2. The mounting support 31 and the limiting support 41 are connected to the front cover assembly 2 by passing fasteners through the connection holes and the fixing holes, so as to facilitate the disassembly and assembly between the front cover assembly 2 and the radiator 1.

[0057] Furthermore, the connection holes on the second connection portion are elongated holes, so as to eliminate the manufacturing error and assembly error of the fasteners.

[0058] The fasteners include components such as bolts, nuts, and gaskets. The combined usage methods of these components are well known to those skilled in the art and will not be elaborated here.

[0059] Specific embodiments of the present application further provide a construction machine, including a front hood assembly 2, a radiator 1, and a radiator mounting structure, and the radiator mounting structure connects the radiator 1 and the front hood assembly 2. Since all embodiments of the construction machine adopt the radiator mounting structure, the construction machine has all the beneficial effects brought by the radiator mounting structure. Among them, the construction machine includes a bulldozer, an excavator, a crane, etc.

[0060] In some embodiments, the front hood assembly 2 includes a front end plate and a plurality of side plates arranged around the front end plate. The front end plate and the plurality of side plates enclose an installation cavity, the radiator 1 is arranged in the installation cavity, the installation component 3 is detachably connected to the side plate and the radiator 1, and the limiting component 4 is detachably connected to the front end plate and the radiator 1. The installation component 3 located on the left side and the limiting component 4 located on the left side are described in detail:

[0061] The installation base 32 is welded to the left side of the radiator 1. The installation support 31 passes through the left side plate of the front hood assembly 2 and is connected to the installation base 32. Among them, the right end face of the first connection part of the installation support 31 is attached to the left end face of the left side plate of the front hood assembly 2 and is provided with a plurality of fasteners for connection. The first sleeve part of the installation support 31 passes through the left side plate of the front hood assembly 2 and is connected to the first pin shaft part of the installation base 32.

[0062] The limiting base 42 is welded to the left side of the radiator 1. The limiting support 41 is located on the right side of the left side plate of the front hood assembly 2, that is, the limiting support 41 is located in the installation cavity. Among them, the front end face of the second connection part of the limiting support 41 is attached to the rear side face of the front end plate of the front hood assembly 2 and is provided with a plurality of fasteners for connection.

[0063] Those skilled in the art can understand that the connection manner of the installation component 3 located on the right side connecting the radiator 1 and the front hood assembly 2 is the same as that of the installation component 3 located on the left side connecting the radiator 1 and the front hood assembly 2, and the connection manner of the limiting component 4 located on the right side connecting the radiator 1 and the front hood assembly 2 is the same as that of the limiting component 4 located on the left side connecting the radiator 1 and the front hood assembly 2, which will not be elaborated. Moreover, the installation component 3 and the limiting component 4 can also be arranged on the upper side or the lower side of the radiator 1 to connect the upper side of the radiator 1 and the front hood assembly 2 or connect the lower side of the radiator 1 and the front hood assembly 2, having a wide application range.
