Accordingly, the scope of the present application is defined only by the following claims. DETAILED DESCRIPTION

[0053] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to all alternative embodiments, as would be understood by one skilled in the art. The following exemplary embodiments are described herein with reference to the figures. In the description of the figures, like parts are marked with the same numerals throughout the figures.

[0055] With the continuous progress of society, the automobile industry is also developing rapidly, and the automobile suspension technology is gradually evolving towards lightweight, emerging new suspension systems such as air suspension and rubber suspension. These innovations not only aim to reduce the overall weight of the vehicle, but also strive to improve the driving experience without affecting the safety performance of the vehicle.

[0056] To achieve both lightweighting and safety in automobiles, existing automotive suspension systems typically employ a tubular beam structure. This design effectively prevents suspension slippage, thereby reducing safety hazards. However, it's worth noting that while the tubular beam structure offers significant safety advantages, it also increases the overall weight of the suspension system to some extent. Therefore, how to further reduce suspension weight while maintaining safety has become one of the major challenges facing automotive engineers today.

[0057] This application provides a balanced suspension and a vehicle thereof, which aims to solve the technical problem in the prior art that automobile suspension cannot simultaneously ensure lightweighting and prevent the suspension from loosening and causing safety hazards.

[0058] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0059] Figure 1 This is a schematic diagram of a balanced suspension structure provided in an embodiment of this application. Figure 1 As shown, the balanced suspension includes: a leaf spring assembly 100 and a thrust assembly 200. The thrust assembly 200 is connected to the vehicle frame 300. The thrust assembly 200 includes an upper thrust component assembly 220 and a lower thrust component assembly 250. The upper thrust component assembly 220 includes a plurality of first upper thrust arms 221 and a plurality of second upper thrust arms 222. The first upper thrust arms 221 and the second upper thrust arms 222 are respectively connected to the vehicle frame 300, and the first upper thrust arms 221 and the second upper thrust arms 222 are connected. The lower thrust component assembly 250 is connected to the vehicle frame 300, and the leaf spring assembly 100 is disposed on the lower thrust component assembly 250.

[0060] The leaf spring assembly 100 is primarily used to bear the vehicle's load, support its weight, absorb and cushion impacts from the road surface, and maintain wheel contact with the ground. The leaf spring assembly 100 can consist of multiple leaf springs, a center clamp, and other connecting components. The leaf springs can be made of composite materials, steel plates, etc., and the multiple leaf springs can be made of single steel or composite materials, or a combination of steel plates and composite plates. The use of composite materials provides the leaf spring assembly 100 with greater design flexibility and corrosion resistance, enabling it to maintain excellent performance even in harsh environments. Furthermore, composite materials typically have a higher specific strength (strength to density ratio), allowing composite leaf springs to be lighter than traditional steel leaf springs while providing the same load-bearing capacity.

[0061] The leaf spring assembly 100 can also be composed of a plurality of end rubber pads, an advanced composite leaf spring, a steel leaf spring, a center rubber pad, a center pressing plate, a plurality of end wear-resistant fixing plates, and a center pin. The advanced composite leaf spring is connected and fixed with the plurality of end rubber pads, the center rubber pad, the end rubber pad right, the end wear-resistant fixing plate, and the plurality of end wear-resistant fixing plates by using hexagonal screws. The two end rubber pads and the two end wear-resistant fixing plates are respectively arranged on the advanced composite leaf spring. A pin hole can be arranged at a middle position of the advanced composite leaf spring. The steel leaf spring is connected and fixed with the advanced composite leaf spring through the center pin. The center pressing plate is connected and fixed with the advanced composite leaf spring through the center pin. After the composite leaf spring is added to the leaf spring assembly 100, the vertical bearing capacity and the service life of the leaf spring assembly 100 are improved. Moreover, compared with the balanced suspension using the composite leaf spring alone, the torsional resistance of the balanced suspension is improved, the problem of easy tearing of the balanced suspension using the pure composite leaf spring under a large torsion is solved, and the safety of the vehicle is improved.

[0062] The frame assembly 200 serves as the load-bearing structure of the vehicle, ensuring the stability and safety of the vehicle under various driving conditions. At the same time, the frame assembly 200 can also consider the selection of materials to achieve the best balance between weight and strength, thereby improving fuel efficiency and vehicle performance. The frame assembly 200 serves as the load-bearing structure of the vehicle, providing sufficient strength and rigidity for mounting other components of the vehicle, such as the suspension system, engine, body, etc. The frame assembly 200 can effectively absorb and disperse irregular impacts and vibrations from the road, improving ride comfort. At the same time, the frame assembly 200 can also be designed modularly, making it flexible to adapt to the needs of different vehicle models, supporting the integration of various configurations and functions, such as electric power systems, battery pack installation, and advanced safety systems.

[0063] The frames 300 and 300' are symmetrically arranged, and the upper push element assembly 220 is arranged between the frames 300 and 300'. The upper push element assembly 220 is fixedly connected with the frames 300 and 300' by welding, bonding, or other methods, or is detachably connected with the frames 300 and 300' by a pin, a bolt, or other methods. The upper push element assembly 220 is also connected with other components in the vehicle. The opposite outer sides of the frames 300 and 300' are respectively connected with the leaf spring assemblies 100. The leaf spring assemblies 100 and the lower push element assembly 250 are fixedly connected by welding, bonding, or other methods, or are detachably connected by a pin, a bolt, or other methods. The leaf spring assemblies 200 can also be connected with other components in the vehicle.

[0064] The plurality of first upper thrust arms 221 and the plurality of second upper thrust arms 222 in the upper thrust component assembly 220 are one-to-one corresponding and connected, for example, one end of the first upper thrust arm 221 and one end of the second upper thrust arm 222 are connected, the other end of the first upper thrust arm 221 and the other end of the second upper thrust arm 222 are respectively connected with the frame 300 and the connection, and the first upper thrust arm 221 and the second upper thrust arm 222 can also form an included angle, which can be less than 180°, such as 60°, 90°, 120°, etc. The first upper thrust arm 221 and the second upper thrust arm 222 can form an equilateral triangle, thereby stably supporting the frame 300 and at the same time, no cross beam component can be installed between the frame 300 and the connection, so that the frame can be effectively stabilized while reducing the weight, avoiding the safety hidden trouble of loose frame.

[0065] The balanced suspension provided by the embodiment of the present application is connected with the frame through the plate spring assembly and the thrust component, and the plate spring assembly is connected with the thrust component. The thrust component includes an upper thrust component assembly and a lower thrust component assembly. The upper thrust component assembly includes a plurality of first upper thrust arms and a plurality of second upper thrust arms, which are respectively connected with the frame and connected with each other. The lower thrust component assembly is connected with the frame, and the plate spring assembly is arranged on the lower thrust component assembly. The balanced suspension provided by the present application forms an included angle less than 180° between the first upper thrust arm and the second upper thrust arm, thereby stably supporting the first frame and the second frame and reducing the setting of the cross beam, so that the balanced suspension can be stably supported while reducing the weight, preventing the suspension from loosening and avoiding the generation of safety hidden trouble.

[0066] Further, on the basis of the above-mentioned embodiment, the structure of the frame assembly is described in more detail, and the above-mentioned embodiment is continued to be referred to Figure 1 The one end of the first upper thrust arm 221 and the one end of the second upper thrust arm 222 are connected, and the connection end of the first upper thrust arm 221 and the second upper thrust arm 222 is further connected with the sleeve joint 210, which is used to connect the power component of the vehicle. The other end of the first upper thrust arm 221 and the other end of the second upper thrust arm 222 are respectively connected with the frame 300.

[0067] The one end of the first upper thrust arm 221 is connected with the second upper thrust arm 222 to form a cooperative force transmission system, which ensures the effective transmission and distribution of force and motion between different components, thereby improving the overall stability and handling performance of the vehicle. The other end of the first upper thrust arm 221 is connected with the opposite inner side of the frame 300, which provides a firm support point and can effectively bear and transmit various forces from the vehicle motion, thereby enhancing the structural integrity of the frame and optimizing the response ability of the vehicle under dynamic conditions. The first upper thrust arm 221 can provide additional support and stability during vehicle turning, acceleration and braking.

[0068] Further, with continued reference to Figure 1 Further, the vehicle frame 300 further comprises a balance shaft assembly 240; the balance shaft assembly 240 is rotatably connected to the vehicle frame 300, and the leaf spring assembly 100 is connected to the balance shaft assembly 240.

[0069] The balance shaft assembly 240 can be used to connect the vehicle frame and the suspension components in the vehicle, such as leaf springs or shock absorbers, etc., which helps to evenly distribute the weight and load of the vehicle, improves the balance and stability of the vehicle during driving, and can improve the handling and safety of the vehicle during cornering, acceleration and braking. The vehicle frame 300 is connected with the balance shaft assembly 240 respectively, the leaf spring assembly 100 is arranged on the balance shaft assembly 240, and the leaf spring assembly 100 and the balance shaft assembly 240 are detachably connected by bolts, pins or the like.

[0070] Further, with continued reference to Figure 1 The balance shaft assembly 240 comprises a balance shaft assembly connecting portion 241; the balance shaft assembly connecting portion 241 is arranged on the balance shaft assembly 240, and the balance shaft assembly connecting portion 241 is used to connect the balance shaft assembly 240 and the vehicle frame 300.

[0071] The balance shaft assembly 240 is provided with at least one balance shaft assembly connecting portion 241, which is used to stably connect the balance shaft assembly 240 to the vehicle frame 300, not only ensuring the firm connection between the two structural parts, but also providing the necessary flexibility to adapt to the dynamic changes of the vehicle under different operating conditions. The balance shaft assembly connecting portion 241 has excellent tensile strength, shear strength and fatigue resistance to ensure the reliability and safety of the connection during long-term use. At the same time, the balance shaft assembly connecting portion 241 is easy to install and disassemble, which facilitates maintenance and replacement, reduces vehicle downtime, and improves maintenance efficiency. During vehicle driving, the bolts on the balance shaft assembly connecting portion 241 help maintain the correct alignment of the balance shaft assembly 240 through their precise positioning and tightening, thereby ensuring the optimal performance of the suspension system, not only improving the handling stability of the vehicle, but also effectively reducing the transmission of vibration and noise.

[0072] Further, with continued reference to Figure 1 The balance shaft assembly 240 is further provided with a second fixing member 230, so that the leaf spring assembly 100 is located between the top end of the second fixing member 230 and the balance shaft assembly 240; the second fixing member 230 is used to fix the leaf spring assembly 100 on the balance shaft assembly 240.

[0073] The second fixing member 230 can be a U-shaped bolt that provides clamping force, allowing the leaf spring assembly 100 to maintain a stable and secure connection to the balance shaft assembly 240 under various dynamic conditions. The U-shaped bolt is typically made of high-strength steel material to withstand various stresses and vibrations from vehicle motion and road irregularities, with excellent tensile strength and fatigue resistance to ensure reliability and durability of the connection over long-term use.
