Description

Technical Field

[0001] This utility model relates to the field of truck crossbeam technology, specifically a crossbeam assembly for heavy-duty trucks. Background Technology

[0002] The crossbeam assembly for heavy-duty trucks is an important component of the truck frame. It is generally located between the upper and lower flanges of the longitudinal beams of the frame and plays a crucial role in ensuring the torsional stiffness of the frame, bearing longitudinal loads, and supporting the main components of the vehicle.

[0003] Crossbeam assemblies for heavy-duty trucks are typically made of high-strength, low-alloy steel sheets, and sometimes lightweight materials such as aluminum alloys are used to reduce the overall weight of the vehicle.

[0004] Currently, crossbeams in heavy-duty trucks are mostly connected to longitudinal beams by welding or bolting. While welding provides high strength at the welded joints, subsequent disassembly requires grinding at the connection points, leading to a decrease in the strength of the crossbeam or longitudinal beam. Bolted connections facilitate disassembly, but over prolonged use, they are prone to loosening, requiring regular inspection and maintenance. Therefore, those skilled in the art have provided a crossbeam assembly for heavy-duty trucks to address the problems mentioned in the background section. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a crossbeam assembly for heavy-duty trucks. This addresses the issue that crossbeams in heavy-duty trucks are typically connected to longitudinal beams via welding or bolting. While welding provides high strength, subsequent disassembly requires grinding at the connection points, leading to a decrease in the strength of the crossbeam or longitudinal beam. Bolted connections facilitate disassembly, but over extended use, they are prone to loosening, necessitating regular inspection and maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crossbeam assembly for heavy-duty trucks, comprising a longitudinal beam and a crossbeam, wherein a positioning groove is provided on the inner wall of the longitudinal beam facing the crossbeam, and movable grooves are provided at both ends of the crossbeam, wherein a groove is provided on one side of the movable groove facing the longitudinal beam, wherein a locking block is provided in the movable groove, wherein a U-shaped extension plate is installed on the front side of the movable groove, and wherein a plug is provided on the side of the locking block facing the U-shaped extension plate.

[0007] Preferably, the crossbeam is engaged with the longitudinal beam via a groove, which makes the two ends of the crossbeam stepped.

[0008] Preferably, the locking block is slidably inserted into the movable groove, and the locking block is inserted into the positioning groove through the movable groove, which can fix the crossbeam placed on the longitudinal beam.

[0009] Preferably, the insertion rod is inserted into the movable slot, and the insertion rod is pressed into contact with the locking block. When the insertion rod is inserted into the movable slot until its tail end is flush with the end of the U-shaped extension plate, the tail end of the insertion rod and the end of the U-shaped extension plate can be welded to fix the insertion rod.

[0010] Preferably, the front and rear sides of the locking block are provided with buckle grooves. The welding position between the tail end of the insertion rod and the end of the U-shaped extension plate is ground by using equipment such as a grinder or angle grinder, the insertion rod is removed, and then the locking block is moved out of the positioning groove through the buckle groove on the locking block, thereby disassembling the crossbar.

[0011] Preferably, the bottom side of the crossbeam is provided with a weight-reducing hole to reduce the weight of the crossbeam.

[0012] Compared with the prior art, this utility model provides a crossbeam assembly for heavy-duty trucks, which has the following advantages:

[0013] Through design, the heavy-duty truck crossbeam assembly of this utility model includes longitudinal beams and crossbeams. The crossbeams have movable slots and recesses at both ends. After the crossbeams and longitudinal beams are aligned, a plug is inserted into the movable slot. The plug presses the locking block through the movable slot and protrudes into the positioning slot on the longitudinal beam, thus fixing the crossbeam placed on the longitudinal beam. Subsequently, the tail end of the plug is welded to the end of the U-shaped extension plate to prevent displacement of the plug and locking block. When the crossbeam needs to be disassembled, the welded position between the tail end of the plug and the end of the U-shaped extension plate can be ground using a grinder, angle grinder, or similar equipment. After grinding away the weld, the plug can be removed, and then the locking block can be moved out of the positioning slot to disassemble the crossbeam. In this utility model, the connection method between the crossbeam and longitudinal beam avoids the problem of reduced strength caused by grinding, and the compression insertion method prevents the crossbeam from loosening due to loose bolts.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a technical solution: a crossbeam assembly for heavy-duty trucks. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 The system includes a longitudinal beam 1 and a transverse beam 2. The transverse beam 2 has a weight-reducing hole 203 on its bottom side to reduce the weight of the transverse beam 2. The longitudinal beam 1 has a positioning groove 101 on its inner wall facing the transverse beam 2. The transverse beam 2 has movable grooves 201 at both ends. The movable grooves 201 have a recess 2011 on one side facing the longitudinal beam 1. A locking block 3 is provided in the movable groove 201. A U-shaped extension plate 202 is installed on the front side of the movable groove 201. A plug rod 4 is provided on the side of the locking block 3 facing the U-shaped extension plate 202.

[0020] Please see Figure 1 , Figure 2 , Figure 3 The crossbeam 2 is engaged with the longitudinal beam 1 via a groove 2011, which makes both ends of the crossbeam 2 stepped. The locking block 3 is slidably inserted into the movable groove 201, and the locking block 3 penetrates the movable groove 201 and is inserted into the positioning groove 101, which can fix the crossbeam 2 placed on the longitudinal beam 1. The inserting rod 4 is inserted into the movable groove 201, and the inserting rod 4 is pressed into the locking block 3. The inserting rod 4 is inserted into the movable groove 201 until its tail end meets the U-shaped extension plate 202. When the ends are aligned, the tail end of the insertion rod 4 can be welded to the end of the U-shaped extension plate 202 to fix the insertion rod 4. The front and rear sides of the locking block 3 are provided with buckle grooves 301. The welding position between the tail end of the insertion rod 4 and the end of the U-shaped extension plate 202 is ground by using equipment such as a grinder or angle grinder. The insertion rod 4 is then removed, and the locking block 3 is moved out of the locking groove 101 by the buckle grooves 301 on the locking block 3 to disassemble the crossbar.

[0021] The heavy-duty truck crossbeam 2 assembly of this utility model includes a longitudinal beam 1 and a crossbeam 2. A positioning groove 101 is provided on the inner side wall of the longitudinal beam 1, and a movable groove 201 is provided at both ends of the crossbeam 2. A groove 2011 is provided on the side of the movable groove 201 facing the end of the crossbeam 2. The groove 2011 makes the two ends of the crossbeam 2 stepped. The groove 2011 allows the crossbeam 2 to engage with the longitudinal beam 1 when the crossbeam 2 is connected to the longitudinal beam 1.

[0022] A locking block 3 is provided in the movable groove 201. The locking block 3 is U-shaped and has a beveled surface on one side. After the crossbeam 2 is aligned with the longitudinal beam 1, the insert rod 4 is inserted into the movable groove 201. The insert rod 4 presses the beveled surface on the locking block 3, thereby pressing the locking block 3 through the movable groove 201 and protruding from the groove 2011. At this time, the locking block 3 is inserted into the positioning groove 101 on the longitudinal beam 1, thereby fixing the crossbeam 2 placed on the longitudinal beam 1. When the insert rod 4 is inserted into the movable groove 201 until its tail end is flush with the end of the U-shaped extension plate 202, the tail end of the insert rod 4 can be welded to the end of the U-shaped extension plate 202 to fix the insert rod 4. This ensures that the insert rod 4 always presses the locking block 3, preventing the locking block 3 from moving and thus preventing the problem of the crossbeam 2 shaking due to the locking block 3 loosening.

[0023] When it is necessary to disassemble the crossbeam 2, the welding position between the tail end of the insertion rod 4 and the end of the U-shaped extension plate 202 can be ground off using equipment such as a grinder or angle grinder. After grinding off the weld point, the insertion rod 4 can be removed. The locking block 3 can be moved out of the locking slot 101 by the locking slot 301 on the locking block 3, thereby disassembling the crossbeam. In this practical connection method between the crossbeam 2 and the longitudinal beam 1, there will be no problem of the crossbeam 2 or longitudinal beam 1 being weakened by grinding, and the use of the compression insertion method will not cause the crossbeam 2 to loosen due to the loosening of the bolts.
