[0046] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0050] The front-end bracket of a vehicle frame is generally connected to the longitudinal beams and front crossbeams of the frame, and is used to install structures such as radiators and cab front mounts. The radiator is typically located between two front-end brackets of the frame. Existing technology provides a lightweight front-end casting for commercial vehicles, comprising a casting body with a cab mount mounting boss for mounting the cab mount. The inner side of the cab mount mounting boss and the adjacent casting body have radiator mounting bosses with mounting holes for mounting the radiator. However, with the development of high-end tractor vehicles, the demand for front-end cooling capacity has increased significantly, requiring radiators to be larger. When the radiator size is large, the aforementioned structure cannot provide sufficient installation space for a large radiator.

[0051] To address the aforementioned issues, this embodiment provides a front-end bracket for the vehicle frame, which can reserve more installation space for the radiator to meet the arrangement requirements of large radiators and can be used in the field of vehicle technology.

[0052] Reference Figures 1-5The front frame support includes a front support 10, a transition support 20, and a rear support 30 connected in sequence. The front support 10 has a front crossbeam mounting part 11 and a radiator mounting part 12. The front crossbeam mounting part 11 is used to mount the front crossbeam; specifically, the front crossbeam mounting part 11 has a front crossbeam mounting hole 111 through which the front crossbeam is mounted. The radiator mounting part 12 is used to mount the radiator; specifically, the radiator mounting part 12 has a radiator mounting hole 121 through which the radiator is mounted. The radiator mounting part 12 is located on the side of the front support 10 closest to the front and rear center lines of the vehicle. The rear support 30 has a first longitudinal beam mounting part 31, which is used to mount a longitudinal beam; specifically, the first longitudinal beam mounting part 31 has a first longitudinal beam mounting hole 311 through which the longitudinal beam is mounted. The transition bracket 20 includes a first transition plate 201 connected to the front bracket 10 and a second transition plate 202 connected to the rear bracket 30. The second transition plate 202 is bent relative to the rear bracket 30 in a direction away from the vehicle's front-rear centerline, thereby reserving more installation space on the side of the second transition plate 202 closer to the vehicle's front-rear centerline. In this embodiment, the rear bracket 30 extends along the vehicle's front-rear direction. The first transition plate 201 is connected to the second transition plate 202, and the first transition plate 201 is bent relative to the second transition plate 202 in a direction away from the vehicle's front-rear centerline, thereby reserving more installation space on the side of the first transition plate 201 closer to the vehicle's front-rear centerline. This, in turn, provides more installation space for the entire transition bracket 20 on the side of the entire transition bracket 20 closest to the vehicle's front-rear centerline, for installing a radiator to meet the arrangement requirements of a large-size radiator. Furthermore, the aforementioned space can also be used to install larger-size equipment such as engines.

[0053] Optionally, in order to reduce the overall weight of the front frame support, the first transition plate 201 of the transition support 20 is provided with a first transition plate weight reduction hole 2011, the second transition plate 202 is provided with a second transition plate weight reduction hole 2021, and the rear support 30 is provided with a rear support weight reduction hole 301. Specifically, the first longitudinal beam mounting part 31 has a plurality of first longitudinal beam mounting holes 311, and the hole walls of the plurality of first longitudinal beam mounting holes 311 are connected by reinforcing ribs, and the rear support weight reduction hole 301 is formed by the surrounding of each reinforcing rib.

[0054] Continue to refer to Figures 1-5 Along the direction close to the front bracket 10, the height of the transition bracket 20 gradually decreases, thereby forming a clearance groove near the front bracket 10. This clearance groove can also be used to place the radiator, thus allowing the front bracket of the frame to provide more installation space for the radiator.

[0055] Continue to refer to Figures 1-5The front support 10 includes a front support body 101 and a support plate 102 disposed on the front support body 101, with the radiator mounting part 12 disposed on the support plate 102. The front frame support also includes a support frame 40, one end of which is connected to the rear support 30, and the other end is connected to the support plate 102. The support frame 40 provides support for the support plate 102, thereby indirectly providing support for the radiator mounting part 12 to increase structural strength. Optionally, a radiator mounting part reinforcing rib is provided on the outer side of the radiator mounting part 12. The radiator mounting part reinforcing rib connects both the radiator mounting part 12 and the support plate 102 to enhance the structural strength of the radiator mounting part 12.

[0056] Continue to refer to Figures 1-5 The front bracket 10, transition bracket 20, rear bracket 30 and support frame 40 surround and form support frame weight reduction hole 403 to reduce the overall weight of the front bracket of the frame.

[0057] Continue to refer to Figures 1-5 The support frame 40 is provided with a front lower protection mounting part 41, which is used to install the front lower protection structure. Specifically, the front lower protection mounting part 41 has a front lower protection mounting hole 411, and the front lower protection structure is installed on the front lower protection mounting part 41 through the front lower protection mounting hole 411.

[0058] Optionally, the support frame 40 includes a first support rod 401 connected to the rear bracket 20, a front lower protective mounting part 41 disposed on the first support rod 401, and two second support rods 402 connected to the first support rod 401. Both second support rods 402 are connected to the support plate 102, thereby providing multiple support points for the support plate 102 to enhance structural strength. More preferably, the connection point of one of the second support rods 402 to the support plate 102 is directly opposite to the radiator mounting part 12, and the other second support rod 402 is connected to the front end of the support plate 102.

[0059] Continue to refer to Figures 1-5The front bracket of the vehicle frame also includes a front cab mounting part 13 for mounting the front cab suspension structure. The front cab mounting part 13 includes a first front cab mounting seat 131 and a second front cab mounting seat 132. Both the first front cab mounting seat 131 and the second front cab mounting seat 132 have front cab suspension mounting holes and are connected to the front bracket 10. The first front cab mounting seat 131 is located below the second front cab mounting seat 132. Along the front-rear direction of the vehicle, the thickness of the first front cab mounting seat 131 is greater than the thickness of the second front cab mounting seat 132. Therefore, while the thickness of the second front cab mounting seat 132 can meet the actual requirements, increasing the thickness of the first front cab mounting seat 131 relative to the second front cab mounting seat 132 can improve the structural strength of the first front cab mounting seat 131, thereby making the installation of the front cab suspension structure more stable. Specifically, the first cab front suspension mounting seat 131 has a first cab front suspension mounting hole 1311, and the second cab front suspension mounting seat 132 has a second cab front suspension mounting hole 1321. The cab front suspension structure is installed on the cab front suspension mounting part 13 through both the first cab front suspension mounting hole 1311 and the second cab front suspension mounting hole 1321.

[0060] Optionally, the cab front suspension mounting portion 13 is U-shaped and also includes a cab front suspension mounting transition portion 133 located between the first cab front suspension mounting seat 131 and the second cab front suspension mounting seat 132, with the first cab front suspension mounting seat 131 and the second cab front suspension mounting seat 132 connected by the cab front suspension mounting transition portion 133.

[0061] Optionally, the first cab front suspension mounting seat 131 is further provided with a first cab front suspension mounting seat reinforcing rib, which is connected to the front bracket body 101 to increase the structural strength of the connection between the first cab front suspension mounting seat 131 and the front bracket body 101.

[0062] Continue to refer to Figures 1-5The rear bracket 30 is further provided with a front suspension leaf spring mounting part 32 for mounting the front suspension leaf spring. The front suspension leaf spring mounting part 32 is U-shaped and includes a first leaf spring mounting plate 321 and a second leaf spring mounting plate 322 spaced apart, and a leaf spring mounting transition plate 323 located between the first leaf spring mounting plate 321 and the second leaf spring mounting plate 322. The front suspension leaf spring mounting part 32 has a front suspension leaf spring mounting hole 324, which passes through the first leaf spring mounting plate 321 and the second leaf spring mounting plate 322 in sequence. The front suspension leaf spring is mounted in the front suspension leaf spring mounting hole 324. Optionally, in order to reduce the weight of the first leaf spring mounting plate 321 and the second leaf spring mounting plate 322, the first leaf spring mounting plate 321 has a first leaf spring mounting plate weight reduction hole 3211, and the second leaf spring mounting plate 322 has a second leaf spring mounting plate weight reduction hole 3221.

[0063] Continue to refer to Figures 1-5 The first leaf spring mounting plate 321 is located closer to the front and rear center lines of the vehicle than the second leaf spring mounting plate 322. The first leaf spring mounting plate 321 is provided with a crossbeam mounting portion 33 for mounting a crossbeam. Specifically, the crossbeam mounting portion 33 has crossbeam mounting holes 331 through which the crossbeam is mounted. The front crossbeam mounting portion 11 and the crossbeam mounting portion 33 are used to mount different crossbeams. Optionally, the crossbeam mounting portion 33 is provided with a crossbeam mounting portion reinforcing rib, which is connected to the first leaf spring mounting plate 321 to enhance the structural strength of the crossbeam mounting portion 33.

[0064] Continue to refer to Figures 1-5 The leaf spring mounting transition plate 323 is provided with a second longitudinal beam mounting part 34 for mounting the longitudinal beam. Specifically, the second longitudinal beam mounting part 34 has a second longitudinal beam mounting hole 341. The longitudinal beam is mounted on the second longitudinal beam mounting part 34 through the second longitudinal beam mounting hole 341. In this embodiment, the second longitudinal beam mounting hole 341 extends in the vertical direction, while the first longitudinal beam mounting hole 311 extends in the horizontal direction, so that the longitudinal beam can be stably connected with the first longitudinal beam mounting part 31 and the second longitudinal beam mounting part 34.

[0065] Continue to refer to Figures 1-5 The front bracket 10 is provided with a first steering gear mounting part 14, and the rear bracket 30 is provided with a second steering gear mounting part 35. Both the first steering gear mounting part 14 and the second steering gear mounting part 35 are used to mount the steering gear, so that a part of the steering gear is mounted in the first steering gear mounting part 14 and the other part is mounted in the second steering gear mounting part 35. Specifically, the first steering gear mounting part 14 has a first steering gear mounting hole 141, and the second steering gear mounting part 35 has a second steering gear mounting hole 351. The steering gear is mounted through both the first steering gear mounting hole 141 and the second steering gear mounting hole 351.

[0066] Continue to refer to Figures 1-5 The first longitudinal beam mounting part 31 has a plurality of first longitudinal beam mounting holes 311, and the second steering gear mounting part 35 has a plurality of second steering gear mounting holes 351. At least some of the first longitudinal beam mounting holes 311 and at least some of the second steering gear mounting holes 351 are coaxial. Specifically, the rear bracket 30 has a plurality of through holes, one side of which is used to mount the steering gear and the other side is used to mount the longitudinal beam, which simplifies the structure.

[0067] Continue to refer to Figures 1-5 This embodiment also provides a vehicle, including two aforementioned front frame supports, a frame, and a radiator. The frame includes two longitudinal beams and several crossbeams disposed between the two longitudinal beams. The two longitudinal beams are connected one-to-one with two first longitudinal beam mounting portions 31. The two ends of the foremost crossbeam are respectively connected to two front crossbeam mounting portions 11. The radiator is located between the two front frame supports and is connected to two radiator mounting portions 12. This front frame support can reserve more installation space on the side of the entire transition support 20 near the front and rear center lines of the vehicle for installing the radiator, thus meeting the arrangement requirements of a large-size radiator.
