Description

Technical Field

[0001] This utility model relates to the field of vehicle suspension technology, and in particular to a highly flexible vehicle suspension that can rotate 90 degrees. Background Technology

[0002] Vehicle suspension is a mechanical system that connects the vehicle frame and the wheels. Its main function is to transmit the forces and torques between the wheels and the vehicle body, and to buffer the impact loads transmitted to the vehicle body from uneven road surfaces, so as to improve the vehicle's ride smoothness, handling stability and ride comfort.

[0003] Chinese Patent Publication No. CN206679065U, published on 20171128, discloses a vehicle suspension system capable of rotating 90 degrees. The system includes a vehicle body with four wheels. Steering motors are installed at the positions of the four wheels. Ball bearings are provided between the steering motors and the vehicle body. The output shaft of the steering motors is connected to a ball frame with a ball bearing shaft at the top. A dual-axis motor is installed on the inner side of the ball frame via a stabilizer bar. A flange is provided on the power output shaft of the dual-axis motor, and the flange is connected to the wheel rim via rim bolts. A speed relay and an electromagnetic brake are installed on the brake shaft of the brake control end of the dual-axis motor, and a bearing is provided between the brake shaft and the ball frame.

[0004] The existing high-flexibility vehicle suspension that can rotate 90 degrees separates the suspension body and installs a rotating motor on the vehicle chassis. The vehicle suspension is then connected to the output end of the rotating motor. In practice, the outer side of the vehicle suspension is not equipped with corresponding support components. The weight of the suspension and the subsequent impact force are entirely applied to the output end of the rotating motor. The vehicle suspension can be further optimized. Therefore, it is urgent to propose a corresponding high-flexibility vehicle suspension that can rotate 90 degrees to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a highly flexible vehicle suspension that can rotate 90 degrees in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A highly flexible vehicle suspension capable of rotating 90 degrees includes a tandem seat, a mounting bracket, and a suspension body integrated on the outside of the tandem seat. A fixing frame is fixedly connected to the outer wall of the tandem seat. Both the fixing frame and the mounting bracket have a C-shaped structure. The bottom of the fixing frame is rotatably connected to the inner wall of the bottom of the mounting bracket via a bearing. A steering motor is fixedly connected to the top of the fixing frame, and the output end of the steering motor is fixedly connected to the top of the fixing frame.

[0008] Preferably, a connecting frame is fixedly connected to the outer wall of the steering motor, and the bottom of the vertical end of the connecting frame is detachably connected to the top of the mounting frame.

[0009] Preferably, a side plate is fixedly connected to the bottom of the vertical end of the connecting frame, and the side plate is fixedly connected to the top of the mounting frame by a fastening rod.

[0010] Preferably, the output end of the steering motor is connected to a central pivot rod via a flange assembly one, the outer wall of the central pivot rod is rotatably connected to the top of the mounting bracket via a rotating shaft, and the bottom of the central pivot rod is fixedly connected to the top of the mounting bracket via a flange assembly two.

[0011] Preferably, mounting plate one and mounting plate two are fixedly connected to the bottom and horizontal end of the mounting bracket, respectively.

[0012] Preferably, a rotating seat and a fixed seat are fixedly connected to the opposite surfaces of the fixed frame and the mounting frame, and the rotating seat and the fixed seat are rotatably connected.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the mounting bracket is fixed to the bottom of the vehicle frame by the cooperation of mounting plate one and mounting plate two with corresponding screws. The fixed bracket is driven to rotate by the steering motor. The fixed bracket is linked to the suspension body and the wheel through the series bracket. In this way, the function of the suspension body is retained. At the same time, the suspension body and the wheel can be rotated up to 90 degrees by the steering motor. This ensures the flexibility of the vehicle suspension. During the rotation of the fixed bracket, the bearing realizes the series connection between the bottom of the fixed bracket and the mounting bracket. The rotating seat rotates synchronously with the fixed seat. This does not affect the driving of the suspension body by the steering motor. It further ensures the stability of the axial rotation of the suspension body, thereby improving the stability of the high-flexibility vehicle suspension that can rotate 90 degrees.

[0015] 2. In this application, after separating the fastening rod and flange assembly one, the steering motor is removed, and after removing the steering motor, the mounting bracket and the suspension body can still maintain a relatively stable state. Similarly, after separating flange assembly two, the mounting bracket can be separated independently, thereby ensuring the convenience of replacing the steering motor and inspecting and maintaining the suspension assembly, thus further improving the ease of use of the highly flexible vehicle suspension that can rotate 90 degrees.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A highly flexible vehicle suspension that can rotate 90 degrees includes a tandem seat 1, a mounting bracket 4, and a suspension body 2 integrated on the outside of the tandem seat 1. A fixing bracket 3 is fixedly connected to the outer wall of the tandem seat 1. Both the fixing bracket 3 and the mounting bracket 4 have a C-shaped structure. The bottom of the fixing bracket 3 is rotatably connected to the inner wall of the bottom of the mounting bracket 4 through a bearing 10. A steering motor 7 is fixedly connected to the top of the fixing bracket 3. The output end of the steering motor 7 is fixedly connected to the top of the fixing bracket 3.

[0025] The mounting bracket 4 is fixed to the bottom of the vehicle frame by the cooperation of mounting plate 5 and mounting plate 6 with corresponding screws. The steering motor 7 drives the fixed bracket 3 to rotate. The fixed bracket 3 is linked to the suspension body 2 and the wheel through the series seat 1. In this way, the function of the suspension body 2 is retained. At the same time, the steering motor 7 can drive the suspension body 2 and the wheel to rotate up to 90 degrees. This ensures the flexibility of the vehicle suspension. During the rotation of the fixed bracket 3, the bearing 10 realizes the series connection between the bottom of the fixed bracket 3 and the mounting bracket 4. The rotating seat 12 rotates synchronously with the fixed seat 11. This does not affect the drive of the steering motor 7 to the suspension body 2. It further ensures the stability of the axial rotation of the suspension body 2, thereby improving the stability of the high-flexibility vehicle suspension that can rotate 90 degrees.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, a connecting bracket 9 is fixedly connected to the outer wall of the steering motor 7. The bottom of the vertical end of the connecting bracket 9 is detachably connected to the top of the mounting bracket 4. A side piece 14 is fixedly connected to the bottom of the vertical end of the connecting bracket 9. The side piece 14 is fixedly connected to the top of the mounting bracket 4 via a fastening rod 15. The output end of the steering motor 7 is connected to a central rotating rod via a flange assembly 1 8. The outer wall of the central rotating rod is rotatably connected to the top of the mounting bracket 4 via a rotating shaft. The bottom of the central rotating rod is fixedly connected to the top of the fixed bracket 3 via a flange assembly 2 13. After separating the fastening rod 15 from the flange assembly 1 8, the steering motor 7 can be removed. After removing the steering motor 7, the fixed bracket 3 and the suspension body 2 can still maintain a relatively stable state. Similarly, after separating the flange assembly 2 13, the fixed bracket 3 can be separated independently. This ensures the convenience of replacing the steering motor 7 and inspecting and maintaining the suspension body 2, thereby further improving the ease of use of the highly flexible vehicle suspension that can rotate 90 degrees.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, mounting plate 5 and mounting plate 6 are fixedly connected to the bottom and horizontal end of mounting bracket 4, respectively, to facilitate the easy assembly and disassembly of mounting bracket 4 from vehicle frame. Rotating seat 12 and fixed seat 11 are fixedly connected to the opposite sides of fixed bracket 3 and mounting bracket 4, respectively. Rotating seat 12 and fixed seat 11 are rotatably connected to each other, thereby further ensuring the stability of the rotational engagement between fixed bracket 3 and mounting bracket 4.

[0028] Working principle: The mounting bracket 4 is fixed to the bottom of the vehicle frame by the cooperation of mounting plate 5 and mounting plate 6 with corresponding screws. The steering motor 7 drives the mounting bracket 3 to rotate. The mounting bracket 3 is linked to the suspension body 2 and the wheel through the series seat 1. This retains the function of the suspension body 2 while allowing the suspension body 2 and the wheel to rotate up to 90 degrees through the steering motor 7, ensuring the flexibility of the vehicle suspension. During the rotation of the mounting bracket 3, the bearing 10 connects the bottom of the mounting bracket 3 with the mounting bracket 4, and the rotating seat 12 rotates synchronously with the mounting seat 11, so as not to affect the steering motor 7's operation on the suspension. While driving the main body 2, the stability of the axial rotation of the suspension main body 2 is further ensured, thereby improving the stability of the high-flexibility vehicle suspension that can rotate 90 degrees. After separating the fastening rod 15 and the flange assembly 8, the steering motor 7 can be taken out. After taking out the steering motor 7, the fixing bracket 3 and the suspension main body 2 can still maintain a relatively stable state. Similarly, after separating the flange assembly 13, the fixing bracket 3 can be separated independently, thereby ensuring the convenience of replacing the steering motor 7 and inspecting and maintaining the suspension main body 2, thus further improving the convenience of using the high-flexibility vehicle suspension that can rotate 90 degrees.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
