Description

Technical Field

[0001] This application relates to the technical field of vehicles, and in particular to a front suspension bracket assembly. Background Technology

[0002] The automotive suspension assembly is an important component of a car. It consists of a series of elastic elements, force transmission devices, and damping devices. Its main function is to connect the wheels and the car body, withstand and buffer impacts from the road, and control the vehicle's driving posture and stability.

[0003] Currently available automotive suspension assemblies, such as the one disclosed in announcement number CN116852925B, include a front wheel suspension assembly structure, which includes a suspension frame. The suspension frame is provided with a steering arm connected to the steering column of the steering wheel. Positioning arms are connected to both sides of the steering arm through steering tie rods. A lower wishbone, a stabilizer bar, and an upper wishbone are arranged sequentially from bottom to top between the suspension frame and the positioning arms.

[0004] Regarding the aforementioned technologies, the inventors discovered that the stiffness of the front suspension can only be adjusted by adjusting the adjustment knob inside the shock absorber itself. However, the adjustment range of the shock absorber itself is small, making it impossible to adjust its stiffness over a wide range and thus failing to meet usage requirements. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a front suspension bracket assembly that has the advantage of meeting the requirements of chassis with different hardness.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] The above technical solution enables the top of the suspension spring to connect with the shock-absorbing hinge plate, thereby completing the installation of the suspension; the positioning claws of the shock-absorbing hinge frame can be locked in different positioning slots to adjust the position of the shock-absorbing hinge plate, thereby adjusting the preload of the suspension spring installed above it to meet the needs of chassis with different hardness; and the C-shaped base is riveted to the top frame to ensure the positional accuracy of the shock-absorbing hinge plate.

[0010] As a preferred embodiment of this application, the lower swing arm bracket includes a lower bracket, on which a pair of U-shaped lower swing arm hinge plates are provided. Both ends of the lower swing arm hinge plates are provided with lower swing arm hinge rings, and the lower swing arm hinge plates are provided with positioning grooves for the lower bracket to be engaged and positioned.

[0011] To achieve the above technical solution, the lower control arm is rotatably connected to the lower control arm bracket via the lower control arm hinge ring. The lower control arm hinge plate is provided with a snap-fit ​​groove for the lower bracket to snap and position. In other words, the snap-fit ​​groove ensures the installation position of the lower control arm hinge ring, thereby ensuring the accuracy of the lower control arm after installation.

[0012] As a preferred embodiment of this application, the upper swing arm bracket includes an upper bracket disposed on the lower bracket, and the upper bracket is provided with two pairs of upper swing arm hinge rings, the upper swing arm hinge rings and the lower swing arm hinge rings being disposed in a one-to-one correspondence.

[0013] The above technical solution enables the upper swing arm to be fixed on the upper swing arm hinge ring, thereby satisfying the installation and use of the upper swing arm.

[0014] As a preferred embodiment of this application, a reinforcing plate is provided between the C-shaped base and the shock-absorbing hinge plate.

[0015] The above technical solution ensures the support strength of the vibration damping hinge plate.

[0022] The following is in conjunction with the appendix Figures 1 to 2 This application will be described in further detail.

[0023] This application discloses a front suspension bracket assembly. (Refer to...) Figure 1 The front suspension bracket assembly includes a lower control arm bracket 1, an upper control arm bracket 2, and a shock absorber bracket 3 arranged sequentially from bottom to top.

[0024] The lower control arm bracket 1 includes a lower support 11, which comprises several intersecting square tubes 111. These square tubes are welded together or cast integrally to ensure structural stability. A pair of U-shaped lower control arm hinge plates 12 are provided on the lower support 11. Both ends of the hinge plates are equipped with lower control arm hinge rings 13, allowing the lower control arm to be rotatably connected to the lower control arm bracket 1 via the hinge rings 13. The lower control arm hinge plates 12 are provided with locking grooves 14 for engaging and positioning the lower support 11. These locking grooves 14 ensure the proper installation position of the lower control arm hinge rings 13, thereby guaranteeing the accuracy of the lower control arm (lower fork arm) after installation.

[0025] The upper swing arm bracket 2 includes an upper bracket set on the lower bracket 11. The upper bracket is composed of a pair of C-shaped plates 21. The upper bracket is welded or riveted to the lower bracket 11. The upper bracket is provided with two pairs of upper swing arm hinge rings 22. The upper swing arm hinge rings 22 and the lower swing arm hinge rings 13 are set one-to-one, so that the upper swing arm is fixed on the upper swing arm hinge rings 22, thereby satisfying the installation and use of the upper swing arm (upper fork arm).

[0026] The shock absorber bracket 3 includes a top frame 31, on which a pair of shock absorber hinge brackets 32 are mounted. Each shock absorber hinge bracket 32 ​​includes a C-shaped base 321, on which a shock absorber hinge plate 324 is mounted. The C-shaped base 321 has a pair of positioning claws 322, and the top frame 31 has several positioning slots 311 for the positioning claws 322 to engage. The C-shaped base 321 and the top frame 31 are riveted together. This allows the top of the suspension spring to connect with the shock absorber hinge plate 324, thus completing the suspension installation. The positioning claws 322 of the shock absorber hinge bracket 32 ​​can engage in different positioning slots 311, thereby adjusting the position of the shock absorber hinge plate 324 and consequently adjusting the preload of the suspension spring mounted above it, thus meeting the requirements of chassis with different hardness. Furthermore, the C-shaped base 321 is riveted to the top frame 31 to ensure the positional accuracy of the shock absorber hinge plate 324. Meanwhile, in order to ensure the support strength of the shock-absorbing hinge plate 324, a reinforcing plate 323 is provided between the C-shaped base 321 and the shock-absorbing hinge plate 324.

[0027] The implementation principle of a front suspension bracket assembly in this application embodiment is as follows: the top of the suspension spring can be connected to the shock-absorbing hinge plate 324 to complete the installation of the suspension; the positioning claws 322 of the shock-absorbing hinge plate 32 can be locked in different positioning slots 311 to adjust the position of the shock-absorbing hinge plate 324, thereby adjusting the preload of the suspension spring installed above it to meet the needs of chassis with different hardness; and the C-shaped base 321 is riveted to the top frame 31 to ensure the positional accuracy of the shock-absorbing hinge plate 324.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
