Description

Technical Field

[0001] This utility model belongs to the field of automotive assembly technology, and in particular relates to a transfer case suspension structure for high-mounted transfer case installation. Background Technology

[0002] In automotive drivetrain systems, the transfer case is a crucial component for achieving multi-wheel drive, distributing power from the transmission to the front and rear drive axles. In high-mounted transfer case designs, the installation location is far from the vehicle frame and the center of gravity is high, placing higher demands on the stability, vibration isolation performance, and reliability of the suspension structure.

[0003] Existing transfer case mounting technologies mostly employ simple rubber bushings or basic bracket structures for connection and cushioning. These structures often suffer from the following drawbacks when dealing with the greater torque and complex vibrations resulting from high-mounted installations: First, their cushioning and damping capabilities are limited, making it difficult to effectively attenuate the mid-to-high frequency vibrations generated by the transfer case, leading to vibration and noise easily being transmitted to the vehicle body, affecting ride comfort. Second, simple mounting structures are prone to excessive displacement or deformation when subjected to loads from various directions, especially impacts from different directions, causing stress concentration in the connecting parts, affecting structural durability, and potentially leading to loosening of the fixing points due to prolonged shaking. Furthermore, traditional mounting structures do not adequately consider the spatial adaptability and installation convenience required for high-mounted installations, making it difficult to achieve stable and efficient support within a compact chassis space.

[0004] To address these issues, we provide a transfer case mounting structure with the transfer case mounted high up. Utility Model Content

[0005] The purpose of this utility model is to provide a transfer case suspension structure for high-position installation of the transfer case. Through the cooperation of the first support frame and the second support frame, the problems of poor vibration reduction effect and insufficient stability of the existing high-position installation suspension structure of the transfer case are solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a transfer case suspension structure for high-position installation of a transfer case, including a fixed plate, a mounting arm movably connected to one side of the fixed plate, a mounting plate fixedly connected to the other end of the mounting arm, a first support frame movably connected to one side of the mounting plate, a sliding rod fixedly connected to the other side of the first support frame, a second support frame slidably connected to the surface of the sliding rod, and a damper movably connected to one side of the first support frame.

[0008] The present invention is further configured such that reinforcing rods are fixedly connected to both sides of the first support frame.

[0009] The present invention is further configured such that the other end of the damper is movably connected to one side of the second support frame, and there are two dampers, with the first support frame and the two dampers forming a triangular support mechanism.

[0010] The present invention is further configured such that a limiting plate is fixedly connected to the other end of the slide rod, and a spring is sleeved on the surface of the slide rod.

[0011] The present invention is further configured such that one end of the spring is fixedly connected to one side of the first support frame, and the other end of the spring is fixedly connected to one side of the second support frame.

[0012] The present invention is further configured such that a first mounting hole is provided on one side of the fixing plate, and one side of the second support frame is movably connected to the bottom of the mounting arm.

[0013] The present invention is further configured such that the mounting plate is L-shaped and a second mounting hole is provided on one side of the mounting plate.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model, by setting an elastic buffer unit composed of a slide bar, a spring, and a second support frame, can effectively absorb and buffer the axial vibration and impact transmitted from the transfer case, reducing the vibration transmission rate to the vehicle body. At the same time, through the triangular support mechanism composed of a first support frame and two dampers, the rigidity and stability of the suspension system in the lateral and longitudinal directions are greatly enhanced, effectively suppressing the lateral swaying and swinging of the transfer case under complex working conditions, and improving the reliability and durability of the overall structure.

[0016] 2. This utility model, through the L-shaped mounting plate design, adapts to the spatial layout requirements when the transfer case is installed in a high position. At the same time, in conjunction with the hinged connection of the mounting arm, it allows the system to adapt to the angle within a certain range, compensating for installation errors and frame deformation, and improving installation convenience and adaptability.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0026] Please see Figures 1-5 This utility model is a transfer case suspension structure for high-position installation of transfer case, including a fixed plate 1, a mounting arm 2 movably connected to one side of the fixed plate 1, a mounting plate 3 fixedly connected to the other end of the mounting arm 2, a first support frame 4 movably connected to one side of the mounting plate 3, a sliding rod 5 fixedly connected to the other side of the first support frame 4, a second support frame 6 slidably connected to the surface of the sliding rod 5, and a damper 7 movably connected to one side of the first support frame 4.

[0027] Further details: Mounting arm 2 is made of high-strength steel, allowing slight vertical sway to compensate for installation errors. Through the triangular support mechanism and the spring 10 damping system, it effectively absorbs multi-directional vibrations of the transfer case, improving operational smoothness and comfort. Spring 10 is a helical compression spring, and its stiffness is designed according to the weight of the transfer case and the vibration frequency to ensure that the resonance frequency is far from the working range. The entire suspension structure reduces the vibration and noise transmitted to the vehicle body through multi-stage buffering and damping, improving vehicle stability and comfort. Example

[0028] Please see Figures 1-5Based on embodiment 1, reinforcing rods 8 are fixedly connected to both sides of the first support frame 4, and the other end of the damper 7 is movably connected to one side of the second support frame 6. There are two dampers 7. The first support frame 4 and the two dampers 7 form a triangular support mechanism. The other end of the slide rod 5 is fixedly connected to a limit plate 9. A spring 10 is sleeved on the surface of the slide rod 5. One end of the spring 10 is fixedly connected to one side of the first support frame 4, and the other end of the spring 10 is fixedly connected to one side of the second support frame 6. A first mounting hole 11 is provided on one side of the fixing plate 1. One side of the second support frame 6 is movably connected to the bottom of the mounting arm 2. The mounting plate 3 is L-shaped, and a second mounting hole 12 is provided on one side of the mounting plate 3.

[0029] Further details: The reinforcing rod 8 enhances the rigidity of the first support frame 4, preventing deformation under load. Two dampers 7 are symmetrically distributed on both sides of the slide rod 5, forming an isosceles triangular support mechanism with the first support frame 4 and the second support frame 6. The triangular support mechanism provides a stable mechanical distribution, reducing the lateral sway of the transfer case during operation. At the same time, when the spring 10 is compressed or stretched due to vibration, the dampers 7 extend and retract synchronously, generating damping force through the internal oil flow, dissipating vibration energy, suppressing the reciprocating bounce of the spring 10, and improving the system damping ratio. The limiting plate 9 prevents the second support frame 6 from detaching from the slide rod 5. The spring 10 is used to buffer axial impact. The spring 10 absorbs vibration energy during compression and rebound and works in conjunction with the dampers 7. The fixing plate 1 is fixed to the vehicle chassis by the mounting bolts and the first mounting hole 11, achieving stable installation of the overall structure. The transfer case is fixedly connected to the mounting plate 3 by the second mounting hole 12 and the mounting bolts. The L-shaped design adapts to the space requirements of high-position installation of the transfer case.

[0030] The working principle of this utility model is as follows: During vehicle operation, road surface excitation is transmitted to the bottom of the vehicle through the wheel suspension system, causing high-frequency vibration of the transfer case. The vibration load is first transmitted to the first support frame 4 through the mounting plate 3. The first support frame 4 is movably connected to the mounting arm 2 and can deflect within a small range to adapt to angle changes. At the same time, the vibration is transmitted to the slide rod 5 and the second support frame 6 through the first support frame 4, causing the second support frame 6 to slide along the slide rod 5 and compress or stretch the spring 10. The elastic deformation of the spring 10 absorbs part of the vibration energy. Meanwhile, the damper 7, which is hinged to the first support frame 4 and the second support frame 6, extends and retracts synchronously, using internal viscous damping to dissipate the remaining vibration energy and reduce the vibration amplitude.

[0031] Through the composite design of spring 10 buffer, damping energy dissipation and multi-directional floating connection, this structure can effectively isolate the vibration of the transfer case from the vehicle body, while meeting the structural stability and impact resistance requirements under high-position installation.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
