Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, specifically relating to a machine cover support beam system. Background Technology

[0002] The hood is assembled with the frame via the hood support beam. During installation, the hood support beam is first connected to the upper wing of the frame, and then the bolts on the hood are locked to the hydraulic locks on the hood support beam, so that the hood is connected to the top of the hood support beam, and then the hood is fixedly connected to the top of the frame.

[0003] However, the traditional engine hood support beam is fixedly connected to the frame, which prevents the engine hood support beam from rotating at a certain angle relative to the upper wing surface of the frame. Due to the machining tolerances in the early stage and the deviations in the later installation, when the position of the bolt on the engine hood and the hydraulic lock of the engine hood support beam deviates significantly, the bolt cannot lock with the hydraulic lock, thus causing the engine hood to be unable to be effectively locked to the engine hood support beam.

[0004] Secondly, the hood support beam base adopts a square structure. When the hood support beam base is connected to the vehicle frame, a bolt needs to be installed at each of the four corners of the support beam base to achieve a fixed connection with the vehicle frame. Therefore, at least eight bolts need to be installed on both sides of the hood support beam. This results in a large number of bolts used to install the hood support beam, which in turn leads to higher precision requirements and increases the difficulty of assembly, making it unfavorable for installation and subsequent maintenance.

[0005] Furthermore, traditional hood support beams only have a hydraulic lock in the middle, which reduces the connection strength between the sides of the hood and the hood support beam. When the vehicle is bumpy, the rear end of the hood is prone to deformation or even cracking due to high-frequency vibration, affecting the service life of the vehicle. Utility Model Content

[0006] This utility model provides a hood support beam system to solve the problem that when the locking bolts on the hood and the hydraulic locks on the hood support beam have a large front-to-back deviation, the locking bolts cannot engage with the hydraulic locks, thus preventing the hood from locking to the hood support beam; the installation of the hood support beam uses a large number of bolts, requiring high precision and increasing the difficulty of assembly, which is not conducive to installation and subsequent maintenance; the hood support beam only has one hydraulic lock in the middle, which reduces the connection strength between the two sides of the hood and the hood support beam, making the rear end of the hood prone to deformation or even cracking due to high-frequency vibration when the vehicle is bumpy.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A hood support beam system, comprising:

[0009] The support beam includes a support beam body and a crossbeam connected to the support beam body. The bottom of the support beam body is hinged to the frame, and the top of the support beam body has multiple hydraulic locks connected to the bolts of the engine hood.

[0010] The tie arm is inclinedly installed between the crossbeam and the frame at both ends of the crossbeam. One end of the tie arm is connected to the crossbeam through a connecting assembly, and the other end of the tie arm is connected to the frame through tie arm mounting bolts.

[0011] The connecting assembly includes a connecting seat and multiple fastening nuts. The connecting seat is connected to the crossbeam and has a connecting hole for mounting the pull arm. Both sides of the pull arm are connected to the connecting seat through at least one fastening nut. By loosening the fastening nuts, the connecting seat moves along the pull arm. Loosening the pull arm mounting bolts causes the pull arm to rotate relative to the frame, so that the support beam rotates relative to the frame by a preset angle, thereby adjusting the relative position of the hydraulic lock and the locking bolt.

[0012] With the above setup, when the position of the bolt on the hood and the position of the hydraulic lock on the support beam deviate and cannot be aligned for installation, the fastening nut of the pull arm connection is loosened, thus de-fastening the pull arm and the connecting seat. One end of the pull arm can move relative to the connecting hole of the connecting seat, allowing the connecting seat to move along the pull arm. Since the end of the pull arm connected to the frame is hinged, and the bottom of the support beam body is also hinged to the frame, when the connecting seat moves along the pull arm, the support beam body can rotate relative to the frame, that is, the support beam can rotate relative to the upper wing surface of the frame. This adjusts the position of the hydraulic lock on the support beam relative to the bolt on the hood, compensating for the deviation and completing the alignment installation. Furthermore, the bottom of the support beam is hinged to the frame, and the pull arm is connected to the frame, making the connection between the support beam and the frame simpler. It eliminates the need for the traditional connection of at least eight bolts, reducing the number of bolted parts, simplifying the assembly process, and improving installation efficiency. Compared to the existing technology where the support beam is fixedly connected to the frame, making the hydraulic lock of the support beam and the bolt in the engine hood relatively fixed and unable to adjust the position of the support beam and the hydraulic lock, the support beam of this application can rotate relative to the upper wing surface of the frame, allowing the support beam to tilt back and forth along the vehicle's direction of travel. This makes the position of the hydraulic lock of the support beam relative to the bolt in the engine hood adjustable, reducing assembly difficulty and production costs, and improving installation efficiency and device reliability.

[0013] The hood support beam system of this utility model also has the following additional technical features:

[0014] The main body of the support beam is formed by bending a whole round tube into an inverted U-shaped structure; the end of the inverted U-shaped structure of the main body of the support beam is connected to a U-shaped bracket, which has a positioning hole for the main beam mounting bolts to pass through. The bracket is hinged to the frame by the main beam mounting bolts passing through the frame and the positioning hole.

[0015] By adopting the above technical solution, the main body of the support beam is made by bending a single round tube. Compared with the existing technology that uses multiple square tubes spliced ​​and welded together, it has higher structural strength and avoids the problem of easy cracking at the joints caused by traditional splicing and welding. The integrated structure of the main body of the support beam improves the support strength and installation accuracy of the support beam. Moreover, the round tube structure of the main body of the support beam is more efficient in processing and manufacturing than square tubes, and is easier to install and fix. In addition, the stress distribution of the round tube is more uniform than that of the square tube, which improves the stability and reliability of the device.

[0016] A rubber sleeve is nested inside the positioning hole to prevent wear between the main beam mounting bolts and the frame caused by vehicle vibration.

[0017] By adopting the above technical solution, a rubber sleeve is connected between the positioning hole of the card holder and the main beam mounting bolt. The main beam mounting bolt needs to pass through the bolt hole on the frame and the positioning hole of the card holder to realize the hinged connection between the frame and the card holder. Due to the vibration of the frame caused by road bumps, the rubber sleeve can reduce the damage to the main beam mounting bolt caused by the frame vibration, thereby improving the service life of the device components.

[0018] The main body of the support beam is connected to radiator mounting brackets for mounting engine radiators on both sides along the vehicle width direction; the radiator mounting brackets include a first bracket and a second bracket, and the first bracket and the second bracket are separated by a preset distance along the height direction.

[0019] By adopting the above technical solution, radiator mounting brackets can be installed on both sides of the main support beam. The radiator mounting brackets serve as the rear mounting brackets for installing the radiator. The rear mounting brackets and the front mounting brackets together form the support structure for installing the radiator. Therefore, the distance between the support beam and the upper wing surface of the frame can be adjusted by adjusting the rotation angle between them. This avoids the installation difficulties caused by the mismatch of the holes between the front and rear mounting brackets, thereby further improving the radiator installation efficiency and assembly accuracy.

[0020] The first bracket has multiple first radiator mounting holes, and the second bracket has multiple second radiator mounting holes; the first and second radiator mounting holes are elongated holes, and the installation position of the radiator relative to the elongated holes is adjusted to achieve an adjustment range for the radiator relative to the vehicle frame along the vehicle's travel direction.

[0021] By adopting the above technical solution, the first heat dissipation mounting hole and the second heat dissipation mounting hole are elongated holes. Compared with ordinary round holes, elongated holes have a longer channel, thereby increasing the installation coverage area of ​​the first heat dissipation mounting hole or the second heat dissipation mounting hole. This, in turn, increases the corresponding adjustment range between the holes during the heat dissipation installation process, making it easier to adjust the installation positioning between the heat dissipation and each elongated hole, and improving assembly efficiency and installation accuracy.

[0022] The top of the main support beam is connected to a hood lock bracket for installing hydraulic locks.

[0023] By adopting the above technical solution, the top of the supporting beam is connected to the machine cover lock bracket for installing the hydraulic lock, thereby realizing the installation and positioning of the hydraulic lock, and also further protecting the hydraulic lock, preventing the entry of external dust, and improving the service life of the hydraulic lock.

[0024] The main body of the support beam has multiple elongated holes at the position corresponding to the connection of the hood lock bracket. The elongated holes extend along the vehicle width direction so that the installation position of the hood lock bracket can be adjusted along the vehicle width direction.

[0025] By adopting the above technical solution, multiple elongated holes are opened on the main body of the support beam. Since the size of the elongated holes is larger than that of ordinary circular holes, the elongated holes have a longer channel, which facilitates the movement of the hood lock bracket along the vehicle width direction during the installation of the hood lock bracket on the main body of the support beam. This allows the hood lock bracket to be adjusted along the vehicle width direction according to the position of the locking bolt. When the hood locking bolt and the hydraulic lock do not correspond, the position of the hood lock bracket relative to the main body of the support beam can be adjusted to further achieve smooth engagement between the hydraulic lock and the locking bolt, improve the accuracy of installation and positioning, and improve assembly efficiency.

[0026] The top of the main support beam is also connected to multiple machine cover damping pads to reduce vibration between the machine cover above the main support beam and the main support beam.

[0027] By adopting the above technical solution, multiple engine cover shock-absorbing pads are installed above the main body of the support beam, which protect the engine cover and the main body of the support beam, and prevent collisions between the top of the engine cover and the main body of the support beam during vehicle bumps, thus avoiding wear between the engine cover or the main body of the support beam and further improving the service life of the device.

[0028] The top of the main body of the support beam is connected to a first hydraulic lock and a second hydraulic lock, which are set at a preset distance apart along the vehicle width direction.

[0029] By adopting the above technical solution, a first hydraulic lock and a second hydraulic lock are installed above the main body of the support beam to achieve a double-lock setting. Compared with the traditional single-lock setting, the locking between the main body of the support beam and the engine cover is more secure. Furthermore, the first hydraulic lock and the second hydraulic lock are separated by a preset distance. Preferably, the first hydraulic lock and the second hydraulic lock are symmetrically arranged on both sides of the main body of the support beam, so that the force between the main body of the support beam and the engine cover is more even. This avoids the risk of vibration deformation or even cracking of the engine cover on both sides along the vehicle's driving direction, which is caused by the traditional use of a single hydraulic lock, and also avoids the impact of stress concentration, thereby improving the service life of the device.

[0030] One side of the main body of the support beam is also connected to a cab tilt pump bracket for installing the tilt pump.

[0031] By adopting the above technical solution, a cab tilting pump bracket is connected to one side of the main support beam, and a tilting oil pump can be installed on the cab tilting pump bracket, realizing centralized assembly and integration of the device, reducing the space occupied, and improving the efficiency of assembly and installation.

[0032] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0033] 1. The support beam of this application includes a support beam body and a crossbeam connected to the support beam body. The bottom of the support beam body is hinged to the vehicle frame. One end of the pull arm is connected to the crossbeam via a connecting assembly, and the other end of the pull arm is connected to the vehicle frame via a pull arm mounting bolt. The connecting assembly includes a connecting seat and multiple fastening nuts. The connecting seat is connected to the crossbeam, and both sides of the pull arm are connected to the connecting seat via at least one fastening nut. When the position of the locking bolt on the engine cover deviates from the position of the hydraulic lock on the support beam, and they do not coincide and cannot be installed, the fastening nuts and pull arm mounting bolts connected to the pull arm are loosened, thereby de-fastening the pull arm to the connecting seat. One end of the pull arm can move relative to the connecting hole of the connecting seat, and the connecting seat can move along the pull arm. Furthermore, due to the loosening of the pull arm mounting bolts, the pull arm... The arm can rotate relative to the frame, and the bottom of the support beam body is hinged to the frame. When the connecting seat moves along the arm, the support beam body can rotate relative to the frame, that is, the support beam can rotate relative to the upper wing surface of the frame. This allows adjustment of the position of the hydraulic lock on the support beam relative to the bolt of the engine cover, compensating for any deviation and completing the docking installation. Compared to the existing technology where the support beam is fixedly connected to the frame, making the position of the hydraulic lock on the support beam and the bolt in the engine cover relatively fixed and unable to adjust the position of the support beam and the hydraulic lock, the support beam of this application can rotate relative to the upper wing surface of the frame, allowing the support beam to tilt back and forth along the vehicle's direction of travel. This makes the position of the hydraulic lock on the support beam relative to the bolt of the engine cover adjustable, reducing assembly difficulty and production costs, and improving installation efficiency and device reliability.

[0034] 2. The main body of the support beam in this application is made by bending a single round tube. Compared with the existing technology that uses multiple square tubes spliced ​​and welded together, it has higher structural strength and avoids the problem of easy cracking at the joints caused by traditional splicing and welding. The integrated structure of the main body of the support beam improves the support strength and installation accuracy of the support beam. Moreover, the round tube structure of the main body of the support beam is more efficient to process and manufacture than square tubes, and is easier to install and fix. In addition, the stress distribution of the round tube is more uniform than that of the square tube, which improves the stability and reliability of the device.

[0035] 3. The support beam body of this application has multiple elongated holes. Since the size of the elongated holes is larger than that of ordinary circular holes, the elongated holes have a longer channel, which facilitates the movement of the hood lock bracket along the vehicle width direction during the installation of the hood lock bracket on the support beam body. This allows the hood lock bracket to be adjusted along the vehicle width direction according to the position of the locking bolt. When the hood locking bolt and the hydraulic lock do not correspond, the position of the hood lock bracket relative to the support beam body can be adjusted to further achieve smooth engagement between the hydraulic lock and the locking bolt, improve the accuracy of installation and positioning, and improve assembly efficiency.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0048] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0049] like Figure 1 The diagram shows a schematic of the existing hinged machine cover support beam. As can be seen, the cover lock 15 is installed on the top of the support beam assembly to connect with the cover's locking bolts. It uses a single cover lock 15 to lock from the middle of the support beam; there are no locking structures on the sides of the cover and the sides of the support beam assembly. Therefore, the locking mechanism between the cover and the support beam assembly is not secure. The support beam assembly is constructed by splicing and welding multiple square tubes 16 together. Therefore, the presence of weld seams at the joints of the support beam assembly reduces the overall structural strength. The bottom of the support beam assembly has a flat base structure on both sides. Each base is rectangular and has a bolt at each of the four corners. A total of 4 bolts are needed to connect each base to the upper wing surface 20 of the frame. A total of 8 bolts are needed to connect the two bases to the upper wing surface 20 of the frame. In addition, one side of the support arm 19 is connected to the support beam assembly, and the other side of the support arm 19 is connected to the upper wing surface 20 of the frame by bolts. Therefore, a total of 2 bolts are needed to connect the two support arms 19 to the upper wing surface 20 of the frame. In other words, a total of 10 bolts are needed to connect the support beam assembly to the upper wing surface 20 of the frame. Furthermore, once the support beam assembly is connected to the upper wing surface 20 of the frame with 10 bolts, the support beam assembly is fixed to the upper wing surface 20. The support beam assembly cannot move or rotate relative to the upper wing surface 20, and the angle between the support beam and the upper wing surface 20 cannot be adjusted. If the position of the hood lock 15 at the top of the support beam assembly deviates from that of the hood bolt, the hood lock 15 cannot change its position relative to the frame 8 because the support beam assembly cannot rotate or move relative to the upper wing surface 20, thus preventing installation between the hood lock 15 and the hood bolt. Therefore, this application requires a novel multi-functional hood support beam system for articulated trucks, enabling the support beam assembly to rotate relative to the upper wing surface 20 of the frame, thereby adjusting the relative position between the hood lock 15 and the bolt.

[0050] This application relates to a hood support beam system, such as Figure 2-5 As shown, it includes:

[0051] The support beam includes a support beam body 1 and a crossbeam 2 connected to the support beam body 1. The bottom of the support beam body 1 is hinged to the frame 8, and the top of the support beam body 1 has multiple hydraulic locks 4 connected to the bolts of the engine cover.

[0052] The pull arm 3 is inclinedly installed between the crossbeam 2 and the frame 8 along both ends of the crossbeam 2. One end of the pull arm 3 is connected to the crossbeam 2 through a connecting assembly, and the other end of the pull arm 3 is connected to the frame 8 through the pull arm mounting bolt 5.

[0053] The connecting assembly includes a connecting seat 6 and multiple fastening nuts 7. The connecting seat 6 is connected to the crossbeam 2 and has a connecting hole for mounting the pull arm 3. Both sides of the pull arm 3 are connected to the connecting seat 6 by at least one fastening nut 7. By loosening the fastening nuts 7, the connecting seat 6 moves along the pull arm 3. Loosening the pull arm mounting bolts causes the pull arm to rotate relative to the frame, so that the support beam rotates relative to the frame 8 by a preset angle, thereby adjusting the relative position of the hydraulic lock 4 and the locking bolt.

[0054] The support beam body 1 involved in this application can rotate relative to the frame 8 to adjust the position of the hydraulic lock 4 on the top of the support beam body 1 relative to the bolt on the engine cover. When the position of the bolt on the engine cover deviates from the position of the hydraulic lock 4 on the support beam and they do not coincide and cannot be installed, the fastening nut 7 connected to the pull arm 3 is loosened, thereby making the pull arm 3 and the connecting seat 6 no longer tightly connected. One end of the pull arm 3 can be movably connected to the connecting hole of the connecting seat 6. The connecting seat 6 can move along the pull arm 3 and loosen the pull arm mounting bolt, so that the pull arm can rotate relative to the frame. When the connecting seat 6 moves along the pull arm 3, the support beam body 1 can be rotated relative to the frame 8, that is, the support beam can be rotated relative to the upper wing surface of the frame 8, thereby adjusting the position of the hydraulic lock 4 on the support beam relative to the bolt on the engine cover, compensating for the deviation and completing the installation. Compared to the existing technology where the support beam is fixedly connected to the frame 8, making the position of the hydraulic lock 4 of the support beam and the bolt in the engine hood relatively fixed and unable to adjust the position of the support beam and the hydraulic lock 4, the support beam of this application can rotate relative to the upper wing surface of the frame 8, so that the support beam can tilt back and forth along the vehicle's driving direction, and the position of the hydraulic lock 4 of the support beam relative to the bolt in the engine hood can be adjusted, reducing assembly difficulty and production costs, and improving installation efficiency and device reliability.

[0055] Furthermore, such as Figure 2As shown, the connecting seat 6 includes a first connecting seat and a second connecting seat. The second connecting seat and the first connecting seat are connected at a preset angle, forming a figure-eight-shaped structure. The first connecting seat is arranged perpendicular to the length direction of the crossbeam 2. One end of the first connecting seat is fixedly connected to the crossbeam 2, and the other end of the first connecting seat is fixedly connected to the first end of the second connecting seat. The second end of the second connecting seat is bent at a preset angle relative to the first end, so that the second end of the second connecting seat and the first end have an arc surface structure. The second end of the second connecting seat extends along the length direction parallel to the crossbeam 2. The second end of the second connecting seat has a connecting hole for connecting the pull arm 3. The end of the pull arm 3 connected to the connecting hole is provided with an external thread. When the pull arm 3 is inserted into the connecting hole, the pull arm 3 is fastened to the connecting seat 6 by tightening the fastening nuts 7 on both sides of the connecting hole.

[0056] During installation, the bottom end of the pull arm 3 is connected to the frame 8 via the pull arm mounting bolt 5. Then, the top of the pull arm 3 is inserted into the connecting hole of the connecting seat 6, and the pull arm 3 is fastened to the connecting seat 6 using the fastening nut 7. This fixes the support beam body 1 to the upper wing surface of the frame 8. When it is necessary to adjust the position of the hydraulic lock 4 of the support beam relative to the locking bolt of the engine cover, the multiple fastening nuts 7 connecting the pull arm 3 to the connecting seat 6, as well as the pull arm mounting bolt 5 at the bottom end of the pull arm, are loosened, allowing the pull arm 3 to... Loosen the connection between the connecting seat 6 and the connecting seat 6, allowing the connecting seat 6 to move relative to the pull arm 3. Loosen the pull arm mounting bolts, allowing the pull arm 3 to rotate relative to the frame. At this time, control the main body 1 of the support beam to rotate back and forth relative to the frame 8, so that the hydraulic lock 4 and the locking bolt of the engine cover are aligned, thereby achieving the engagement connection between the hydraulic lock 4 and the locking bolt. In practical applications, a certain number of shims can also be added between the hydraulic lock 4 and the locking bolt to achieve a tight engagement between the hydraulic lock 4 and the locking bolt. The number of shims can be determined according to the actual needs of the site.

[0057] As a preferred implementation method, such as Figure 2 and Figure 3 As shown, the main body of the support beam 1 is formed by bending a whole round tube to form an inverted U-shaped structure; the end of the inverted U-shaped structure of the main body of the support beam 1 is connected to a U-shaped bracket 9, the bracket 9 has a positioning hole for the main beam mounting bolt 10 to pass through, and the bracket 9 is hinged to the frame 8 by the main beam mounting bolt 10 passing through the frame 8 and the positioning hole.

[0058] The main body 1 of the support beam is made by bending a single round tube. Compared with the existing technology that uses multiple square tubes 16 spliced ​​and welded together, it has higher structural strength and avoids the problem of easy cracking at the joints caused by traditional splicing and welding. The integrated structure of the main body 1 of the support beam improves the support strength and installation accuracy of the support beam. Moreover, the round tube structure of the main body 1 of the support beam is more efficient to process and manufacture than the square tube 16, and is easier to install and fix. In addition, the stress distribution of the round tube is more uniform than that of the square tube 16, which improves the stability and reliability of the device.

[0059] Furthermore, the two tie arms 3 of this application are connected to the frame 8 by tie arm mounting bolts 5, and the bottom of the support beam body 1 is hinged to the frame 8 by the main beam mounting bolts 10. Compared with the traditional method that requires 10 bolts to fix the support beam to the frame 8, this application only requires 4 bolts to install the support beam body 1 to the frame 8. Compared with the traditional technical solution, this application uses fewer parts, has a simpler structure, reduces production costs, and improves work efficiency.

[0060] As a preferred embodiment, a rubber sleeve is nested inside the positioning hole to prevent wear between the main beam mounting bolt 10 and the frame 8 caused by vehicle vibration.

[0061] A rubber sleeve is connected between the positioning hole of the card holder 9 and the main beam mounting bolt 10. The main beam mounting bolt 10 needs to pass through the bolt hole on the frame 8 and the positioning hole of the card holder 9 to achieve the hinged connection between the frame 8 and the card holder 9. Due to the vibration of the frame 8 caused by road bumps, the rubber sleeve can reduce the damage to the main beam mounting bolt 10 caused by the vibration of the frame 8, thereby improving the service life of the device components.

[0062] like Figure 4 As shown, a hinge seat is provided at the connection position between the frame 8 and the card holder 9. The hinge seat can be hinged to the card holder 9 through the main beam mounting bolt 10. The structure of the hinge seat and the card holder 9 are adapted to each other, which enhances the connection stability and connection strength between the card holder 9 and the frame 8. The hinge seat is set inside the card holder 9. Bolt holes corresponding to the positioning holes are opened on the hinge seat. The height dimension of the hinge seat is smaller than the dimension of the card holder 9, so that the card holder 9 is not restricted in its rotation angle when rotating relative to the frame 8, and the card holder 9 has a rotation radius space when rotating relative to the frame 8.

[0063] As a preferred implementation method, such as Figure 2 and Figure 5 As shown, the main body of the support beam 1 is connected to radiator mounting brackets 11 on both sides along the vehicle width direction for mounting engine radiators; the radiator mounting brackets 11 include a first bracket 111 and a second bracket 112, and the first bracket 111 and the second bracket 112 are separated by a preset distance along the height direction.

[0064] Preferably, the first bracket 111 and the second bracket 112 have the same structure, and the first bracket 111 is disposed above the second bracket 112.

[0065] By installing radiator mounting brackets 11 on both sides of the main support beam 1, the radiator can be installed on the radiator mounting brackets 11. The radiator mounting brackets 11 serve as the rear mounting brackets for installing the radiator. The rear mounting brackets and the front mounting brackets together serve as the support structure for installing the radiator. Therefore, the distance between the support beam and the front mounting bracket can be adjusted by adjusting the rotation angle between the support beam and the upper wing surface of the frame 8. This avoids the installation difficulty caused by the mismatch of the holes between the front and rear mounting brackets, thereby further improving the radiator installation efficiency and assembly accuracy.

[0066] In a preferred embodiment, the first bracket 111 has a plurality of first radiator mounting holes, and the second bracket 112 has a plurality of second radiator mounting holes; the first and second radiator mounting holes are elongated holes, and the mounting position of the radiator relative to the elongated holes is adjusted to achieve an adjustment amount of the radiator relative to the frame 8 along the vehicle travel direction.

[0067] The first and second heat dissipation mounting holes are elongated holes, which have a longer channel than ordinary round holes. This increases the installation coverage area of ​​the first or second heat dissipation mounting hole, thereby increasing the adjustment range between the holes during heat dissipation installation. This facilitates the adjustment of the installation positioning between the heat dissipation and each elongated hole, improving assembly efficiency and installation accuracy.

[0068] In a preferred embodiment, the top of the support beam body 1 is connected to a hood lock bracket 12 for installing the hydraulic lock 4.

[0069] The top of the supporting beam body 1 is connected to the cover lock bracket 12 for installing the hydraulic lock 4, thereby realizing the installation and positioning of the hydraulic lock 4, and also further protecting the hydraulic lock 4, preventing the entry of external dust, and improving the service life of the hydraulic lock 4.

[0070] In a preferred embodiment, the support beam body 1 has multiple elongated holes at the position corresponding to the connection of the hood lock bracket 12. The elongated holes extend along the vehicle width direction so that the mounting position of the hood lock bracket 12 can be adjusted along the vehicle width direction.

[0071] Multiple elongated holes are provided on the main body 1 of the support beam. Since the size of the elongated holes is larger than that of ordinary round holes, the elongated holes have a longer channel, which facilitates the movement of the hood lock bracket 12 along the vehicle width direction during the installation of the hood lock bracket 12 on the main body 1 of the support beam. This allows the hood lock bracket 12 to be adjusted along the vehicle width direction according to the position of the lock bolt. When the position of the hood lock bolt and the hydraulic lock 4 do not correspond, the position of the hood lock bracket 12 relative to the main body 1 of the support beam can be adjusted to further achieve smooth engagement between the hydraulic lock 4 and the lock bolt, improve the accuracy of installation and positioning, and improve assembly efficiency.

[0072] Preferably, three elongated holes are made on each side of the support beam body 1, and two machine cover lock brackets 12 are fixedly connected to one side of the support beam body 1 by passing bolts through each elongated hole.

[0073] In a preferred embodiment, a plurality of machine cover damping pads 13 are also connected to the top of the support beam body 1 to reduce the vibration between the machine cover above the support beam body 1 and the support beam body 1.

[0074] Multiple engine cover shock-absorbing pads 13 are installed above the main body of the support beam 1 to protect the engine cover and the main body of the support beam 1, and to prevent collisions between the top of the engine cover and the main body of the support beam 1 during vehicle bumps, which would cause wear between the engine cover or the main body of the support beam 1, thereby further improving the service life of the device.

[0075] Preferably, a hood damping pad 13 is connected to each of the two sides of the top of the support beam body 1, and the hood damping pad 13 is disposed on the side of the support beam body 1 away from the hood lock bracket 12.

[0076] Furthermore, the top of the supporting beam body 1 is connected to a first hydraulic lock and a second hydraulic lock, which are set at a preset distance apart along the vehicle width direction.

[0077] A first hydraulic lock and a second hydraulic lock are installed above the main body of the support beam 1, realizing a double-lock setting. Compared with the traditional single-lock setting, the locking between the main body of the support beam 1 and the engine cover is more secure. Furthermore, the first hydraulic lock and the second hydraulic lock are separated by a preset distance. Preferably, the first hydraulic lock and the second hydraulic lock are symmetrically arranged on both sides of the main body of the support beam 1, thereby making the force between the main body of the support beam 1 and the engine cover more even. Since vehicle bumps can easily cause vibration of the vehicle body, the rear sides of the engine cover are prone to deformation or even cracking under the vibration of the vehicle body because there is no hydraulic lock and bolt for locking connection. By setting a hydraulic lock on each side of the top of the main body of the support beam, the risk of vibration deformation or even cracking of the engine cover on the front and rear sides along the vehicle driving direction caused by the traditional use of a single hydraulic lock 4 is avoided, as well as the impact of stress concentration is avoided, thereby improving the service life of the device.

[0078] In a preferred embodiment, a cab tilting pump bracket 14 for mounting the tilting oil pump is also connected to one side of the support beam body 1.

[0079] One side of the main body 1 of the support beam is connected to the cab tilting pump bracket 14, on which the tilting oil pump can be installed, realizing centralized assembly and integration of the device, reducing the space occupied, and improving the efficiency of assembly and installation.
