Description

Technical Field

[0001] This utility model relates to the technical field of truck chassis suspension components, and in particular to a lightweight truck cab suspension bracket. Background Technology

[0002] In the truck manufacturing industry, lightweighting is the core development direction for improving fuel economy and reducing transportation costs. As a key load-bearing component of the chassis, the balance between lightweight design and structural strength of the cab suspension bracket is particularly important.

[0003] Existing truck cab suspension brackets have many technical defects, such as the difficulty in balancing lightweight and strength. Traditional brackets mostly use solid steel plate welding or casting structures, which often result in excessive weight in order to ensure strength, thus failing to meet the requirements of lightweighting. If the material thickness is simply reduced or simple holes are made, the structural strength will be insufficient, and long-term use will easily lead to deformation and cracking. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a lightweight truck cab suspension bracket, the specific technical solution of which is as follows: A lightweight truck cab suspension bracket includes: a crossbeam body comprising a crossbeam column, both ends of which have Y-shaped connecting beams, the first end of which is connected to the end of the crossbeam column; a connecting body comprising a connecting frame with a U-shaped cross-sectional area, the bottom of which is connected to the second end of the Y-shaped connecting beam, the connecting frame having at least one side through hole on both sides along its width direction, the side through hole penetrating the interior of the connecting frame, and at least one top through hole on the top of the connecting frame, the top through hole penetrating the interior of the connecting frame; and a mounting body comprising an integrally formed base frame and a reinforcing plate, the base frame and / or the reinforcing plate having an opening structure, the top of which is connected to the third end of the Y-shaped connecting beam.

[0005] Preferably, the inner side of the connecting frame is provided with at least one reinforcing rib block and a U-shaped reinforcing rib frame, and both ends of the U-shaped reinforcing rib frame and the reinforcing rib block are fixedly connected to the inner side wall of the connecting frame to support the connecting frame.

[0006] Preferably, a buffer pad is connected between the outer wall of the U-shaped reinforcing frame and the inner wall of the connecting frame, and the buffer pad abuts against the connecting frame and the U-shaped reinforcing frame.

[0007] Preferably, the base frame is F-shaped, and the opening structure includes at least one bottom through hole formed on the reinforcing plate.

[0008] Preferably, it also includes a connecting rod, one end of which is connected to the top side of the base frame, and the other end of which is connected to the outer side wall of the connecting frame.

[0009] Preferably, the crossbeams, Y-shaped connecting beams, connecting frames, and base frames are all made of aluminum alloy.

[0010] The beneficial effects of this utility model are: 1. The main body of the crossbeam, the connecting body, the mounting body and the connecting rod are made of high-strength aluminum alloy. With the hollow structure, U-shaped groove design and opening design, the overall weight of the bracket is greatly reduced while ensuring that the structural strength meets the load-bearing requirements. Compared with traditional steel brackets, the weight is reduced by 30%-40%, which is in line with the trend of lightweight truck development.

[0011] 2. The Y-shaped connecting beam's bifurcated structure disperses the load, avoiding localized stress concentration; the reinforcing ribs on the inner side of the connecting frame and the U-shaped reinforcing rib frame form cross supports, enhancing local and overall rigidity; the F-shaped base frame and the reinforcing plate are integrally molded, improving longitudinal support strength; the diagonal support of the connecting rod further enhances the anti-tilting ability, ensuring that the bracket is not easily deformed or cracked during long-term use.

[0012] 3. The buffer pad between the U-shaped reinforcing frame and the connecting frame can absorb vibration and impact, avoiding abnormal noise caused by rigid contact; the connecting rod adopts a ball joint for rotational connection, which can adapt to changes in angle while weakening vibration transmission, effectively reducing the vibration transmitted to the cab during truck operation and improving driving comfort.

[0013] 4. The connecting frame has multiple sets of side and top through holes, which can be flexibly selected to fix the position according to the mounting hole positions of different cab specifications; the bottom through holes of the underframe can also be adapted to the installation requirements of different frames, without the need for separate design for specific models, and has strong versatility.

[0014] 5. Most of the components adopt mature processes such as stamping, die casting, and welding, which are easy to process and have high production efficiency. Although the unit price of high-strength aluminum alloy is higher than that of ordinary steel, the amount of material used is reduced through structural optimization, and the fuel economy improvement brought about by lightweighting can cover the initial cost, resulting in a significant overall cost-performance advantage.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Example Please refer to Figures 1-3 This utility model provides a lightweight truck cab suspension bracket, including a crossbeam body, a connecting body, an installation body, and a connecting rod 5.

[0019] Specifically, the main beam, as the core load-bearing and connecting component, includes the beam column 1 and two sets of Y-shaped connecting beams 2.

[0020] The crossbeam column 1 is a cylindrical hollow structure made of high-strength aluminum alloy. Compared with traditional solid steel, it significantly reduces weight while ensuring strength. The crossbeam column 1 is set horizontally to bear and transfer the longitudinal load of the cab. The Y-shaped connecting beam 2 is an integrally formed bifurcated structure, made of the same high-strength aluminum alloy as the crossbeam column 1. The first end of each Y-shaped connecting beam 2 is fixedly connected to the end of the crossbeam column 1 by welding. The weld is a full welding process to ensure a stable connection. The bifurcated structure of the Y-shaped connecting beam 2 can distribute the load of the crossbeam column 1 to the connecting body and the installation body, avoiding local stress concentration.

[0021] Specifically, the connecting body includes a connecting frame 3, a reinforcing rib block 33, a U-shaped reinforcing rib frame 34, and a buffer pad 340.

[0022] The connecting frame 3 is a U-shaped channel structure made of high-strength aluminum alloy. The U-shaped structure combines lightweight and torsional strength. The bottom of the connecting frame 3 can be fixedly connected to the second end of the Y-shaped connecting beam 2 by bolts to ensure connection reliability. The connecting frame 3 has at least one side through hole 32 on each side along the width direction and at least one top through hole 31 on the top. Both the side through holes 32 and the top through hole 31 pass through the interior of the connecting frame 3 and are used to fix it to the connecting parts at the bottom of the cab by bolts. The multiple through hole design can be adapted to the mounting hole positions of different cab specifications, improving versatility. The reinforcing rib 33 is a triangular block structure made of high-strength aluminum alloy. At least two ribs are provided and symmetrically fixed to the inner wall of the connecting frame 3. Both ends of the ribs are fixed to the inner wall of the connecting frame 3 by welding. This is used to enhance the local structural strength of the connecting frame 3 and prevent deformation caused by stress concentration in the opening area. The U-shaped reinforcing rib frame 34 is a U-shaped structure that adapts to the inner contour of the connecting frame 3. It is made of high-strength aluminum alloy. Its two ends are fixedly connected to the inner wall of the connecting frame 3 by welding, forming a cross support structure with the reinforcing rib block 33, which further improves the overall rigidity and deformation resistance of the connecting frame 3. The buffer pad 340 is made of rubber and has good elasticity and shock absorption performance. It is bonded and fixed between the outer wall of the U-shaped reinforcing frame 34 and the inner wall of the connecting frame 3 through vulcanization process. The buffer pad 340 is in close contact between the two, which can absorb the vibration and impact during the truck's operation, prevent abnormal noise caused by rigid contact between the connecting frame 3 and the U-shaped reinforcing frame 34, and reduce the transmission of vibration to the cab.

[0023] The main installation unit includes an integrally molded base frame 4 and a reinforced version 41, which are made of high-strength aluminum alloy through die casting, resulting in a stable structure and lightweight design.

[0024] The base frame 4 is F-shaped. The F-shaped structure can optimize the force transmission path and improve the support stability. The top of the base frame 4 can be fixedly connected to the third end of the Y-shaped connecting beam 2 by bolts to ensure the coordinated force of the connecting body and the installation body. The reinforcing plate 41 is a flat plate structure integrally formed with the base frame 4 and is vertically set in the middle of the base frame 4 to enhance the longitudinal support strength of the base frame 4 and prevent the base frame 4 from bending under force. The opening structure includes at least one bottom through hole 410 opened on the reinforcing plate 41. The bottom through hole 410 is used to fix the base frame 4 to the truck frame by bolts, thereby fixing the entire suspension bracket. At the same time, the opening design further reduces the overall weight and meets the requirements of lightweighting.

[0025] The connecting rod is a cylindrical hollow structure made of high-strength aluminum alloy. One end is rotatably connected to the top side of the base frame 4 via a ball joint, and the other end is also rotatably connected to the outer side wall of the connecting frame 3 via a ball joint. The rotatable connection method of the ball joint can adapt to angle changes during cab tilting or vehicle movement, avoiding stress concentration caused by rigid connection. The connecting rod 5 forms an oblique support structure, which further enhances the connection stability between the connecting body and the installation body, disperses the lateral load, and improves the anti-tilting ability of the entire suspension bracket.

[0026] Working principle 1. Load bearing and force transmission: The weight of the cab is transmitted to the connecting frame 3 through the top through hole 31 and the side through hole 32. The connecting frame 3 distributes the load to the crossbeam column 1 and the base frame 4 through the Y-shaped connecting beam 2. The crossbeam column 1 bears the longitudinal load and transmits it to the Y-shaped connecting beam 2 at the other end. The base frame 4 transmits the load to the truck frame through the bottom through hole 410, so as to achieve uniform transmission of the entire load and avoid local stress concentration.

[0027] 2. Lightweight and strength assurance: The high-strength aluminum alloy material and hollow, open structure significantly reduce the overall weight. At the same time, the bifurcated structure of the Y-shaped connecting beam 2, the reinforcing ribs 33 and U-shaped reinforcing rib frames 34 on the inner side of the connecting frame 3, the F-shaped base frame 4 and the reinforcing plate 41, and the diagonal support of the connecting rod 5 together form a stable load-bearing structure, ensuring that the bracket meets the requirements of load-bearing and deformation resistance while being lightweight.

[0028] 3. Buffering and shock absorption: When the vibration and impact generated during the truck's operation are transmitted to the support, the buffer pad 340 between the connecting frame 3 and the U-shaped reinforcing rib frame 34 absorbs part of the vibration energy through elastic deformation, reducing the abnormal noise generated by rigid collision; the ball joints at both ends of the connecting rod 5 can adapt to the angle changes caused by vibration, avoid stress transmission caused by rigid connection, further weaken the impact of vibration on the cab, and improve driving comfort.

[0029] 4. Installation and Adaptation: Based on the mounting hole positions of different specifications of cabs and frames, select the corresponding top through hole 31, side through hole 32 on the connecting bracket 3 and the bottom through hole 410 on the base frame 4 for bolt fixing. Adaptation and installation can be completed without modifying the bracket structure, improving installation convenience and versatility.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
