Description

Technical Field

[0001] This utility model relates to the field of automotive suspension system technology, and in particular to a novel automotive suspension structure. Background Technology

[0002] In modern automotive design, double wishbone suspension is widely used in various models due to its excellent handling performance and ride comfort. A double wishbone suspension mainly consists of components such as the upper control arm, lower control arm, shock absorber strut, wheel hub, and steering knuckle. Among these, the steering knuckle (also known as the steering bracket) is a key component, not only bearing various forces and torques from the road surface but also serving as a crucial hub connecting the wheel to the subframe. Traditional one-piece steering knuckle designs typically mold all the travelers as a single piece, including but not limited to the travelers used to mount brake calipers, upper and lower control arms, steering tie rods, and the wheel hub to which they rotate. Although existing steering knuckle designs can meet basic functional requirements, if a specific traveler on the steering knuckle is damaged or deformed due to an accident or long-term use, the entire steering knuckle assembly often needs to be replaced. This not only increases vehicle maintenance costs but also causes unnecessary waste of resources and prolongs repair time. Furthermore, due to the high strength requirements of steering knuckle materials and the complexity of manufacturing processes, the cost of replacing the entire assembly is high, posing an economic burden on both vehicle owners and service providers. To overcome the above-mentioned defects, it is necessary to develop a new type of steering knuckle assembly that can be conveniently replaced after partial damage while ensuring the original mechanical performance and safety standards, thereby effectively reducing maintenance costs and saving resources.

The main steering knuckle has a limiting groove, the wheel hub mounting seat has a limiting platform in the middle that abuts against the limiting groove, and the wheel hub mounting seat has an installation opening in the middle for rotating and installing the wheel hub.

[0006] Preferably, the steering knuckle support has a plurality of screw holes, and the screw holes are provided with fixing bolts. The fixing bolts penetrate the main steering knuckle, the screw holes and the wheel hub mounting seat to fix the steering knuckle support, the main steering knuckle and the wheel hub mounting seat together.

[0007] Preferably, the disc brake disc is annular, and the inner edge of the disc brake disc is fixed to the outer edge of the wheel hub by bolts.

[0008] Preferably, the steering knuckle support has two threaded holes on its left side, and the brake caliper is provided with a screw for threaded connection to the threaded holes.

[0009] Preferably, the steering knuckle support has positioning plates integrally formed on both the upper and lower sides of the tie rod mounting bracket, and the positioning plates are fixedly connected to the tie rod mounting bracket by a second bolt.

[0010] Preferably, rubber pads are provided between the upper and lower sides of the steering knuckle support and the positioning plate.

[0011] In summary, the beneficial effects of this utility model are as follows:

[0012] 1. By subdividing the steering knuckle assembly into the steering knuckle support, main steering knuckle, and wheel hub mount, a modular design is achieved. This design allows for the replacement of only the damaged part, rather than the entire steering knuckle assembly, when any one of the knuckles or components is damaged, significantly reducing maintenance costs and improving resource utilization.

[0023] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example:

[0025] like Figures 1 to 5 As shown, this utility model discloses a novel automotive suspension structure, including a shock absorber strut 1, an upper control arm 2, a lower control arm 3, a wheel hub 4, and a steering knuckle assembly. The steering knuckle assembly specifically includes a steering knuckle support 5, a main steering knuckle 6, and a wheel hub mounting seat 7. The wheel hub mounting seat 7 and the main steering knuckle 6 are respectively fixedly mounted on the front and rear sides of the steering knuckle support 5, while the wheel hub 4 is rotatably mounted on the wheel hub mounting seat 7. Furthermore, a disc brake disc 8 is fixedly connected to the wheel hub 4, and a brake caliper 9 for cooperating with the disc brake disc 8 is fixedly connected to the left side of the steering knuckle support 5. Additionally, an upper control arm mounting bracket 61 and a lower control arm mounting bracket 62 are integrally formed on the upper and lower sides of the main steering knuckle 6, respectively, while a tie rod mounting bracket 63 is fixedly connected to the right side of the main steering knuckle 6. The upper control arm 2 is mounted on the upper control arm mounting bracket 61, and the lower control arm 3 is mounted on the lower control arm mounting bracket 62. The shock absorber strut 1 is connected to the lower control arm 3. This invention achieves a modular design by subdividing the steering knuckle assembly into a steering knuckle support 5, a main steering knuckle 6, and a wheel hub mounting base 7. This design allows for the replacement of only the damaged part, rather than the entire steering knuckle assembly, when any knuckle or component is damaged, thus significantly reducing maintenance costs and improving resource utilization. Furthermore, it simplifies the maintenance process, shortens repair time, and improves work efficiency. It should also be noted that the automotive suspension structure shown in the drawings of this invention is primarily for the rear wheels of front-wheel-drive vehicles. If applied to the front wheels, the position of the shock absorber strut 1 needs to be moved to the left and right sides to prevent the shock absorber strut 1 from blocking the center of the steering knuckle support 5 and hindering the car's driveshaft from driving the wheel hub 4.

[0026] The specific installation structure of the steering knuckle support 5, the main steering knuckle 6, and the wheel hub mounting seat 7 in this utility model is as follows: A central opening 51 is provided in the middle of the steering knuckle support 5, and the main steering knuckle 6 and the wheel hub mounting seat 7 are both installed and fitted in the central opening 51, so that the main steering knuckle 6 and the wheel hub mounting seat 7 can be accurately positioned and stably installed on the steering knuckle support 5.

The fixing bolts 53 penetrate the main steering knuckle 6, the threaded through holes 52, and the wheel hub mounting seat 7 to fix the steering knuckle support 5, main steering knuckle 6, and wheel hub mounting seat 7 together. The application of threaded through holes 52 and fixing bolts 53 not only provides a convenient and robust assembly method but also facilitates disassembly and replacement, making maintenance work simpler and more efficient. At the same time, this design helps maintain the overall rigidity of the steering knuckle assembly, ensuring its long-term stable operation.

[0027] The specific structure of the disc brake disc 8 fixed on the wheel hub 4 is as follows: the disc brake disc 8 is ring-shaped, and the inner edge of the disc brake disc 8 is fixed to the outer edge of the wheel hub 4 by bolts.

[0028] The specific structure of the brake caliper 9 fixed on the steering knuckle support 5 is as follows: two threaded holes 54 are opened on the left side of the steering knuckle support 5, and the brake caliper 9 is provided with a screw 55 for threaded connection on the threaded holes 54.
