[0002] The suspension system is an important support and buffer component of a vehicle. Its function is to support the weight of the vehicle body and absorb and reduce vibrations caused by uneven road surfaces. The rear suspension bracket is a key component that connects the frame and the suspension system and bears the load from the road and the vehicle body.

[0003] Existing rear suspension brackets are typically made of materials such as steel or aluminum alloys. While they possess a certain level of strength and rigidity, they are prone to fatigue, breakage, or deformation after bearing heavy loads or prolonged use. This leads to a decrease in the stability of the suspension system, thereby affecting the vehicle's safety and comfort.

[0004] Therefore, those skilled in the art have provided a high-strength rear suspension bracket to solve the problems mentioned in the background art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figure 1-5 A high-strength rear suspension bracket includes a brake disc fixing body 1, with a reinforcing mechanism 2 disposed above the brake disc fixing body 1. The reinforcing mechanism 2 includes a connecting plate 201, a support frame 208 fixedly connected to the bottom surface of the connecting plate 201, a base plate 209 fixedly connected to the bottom surface of the support frame 208, and two movable frames 202 fixedly connected to the front surfaces of the connecting plate 201 and the base plate 209. The inner walls of the two movable frames 202 are hinged together to a connecting frame 204, and the inner walls of the other two movable frames 202 are hinged together to a V-shaped frame 211. Two fixed seats 207 are fixedly connected to the upper surface of the V-shaped frame 211, and a connecting rod 212 is rotatably connected to the inner walls of the two fixed seats 207. Three shock absorbers 203 are movably hinged to the outer surface of 212. The outer surface of each shock absorber 203 is fixedly connected to the outer surface of the connecting plate 201. A U-shaped plate 205 is provided on the outer side of the V-shaped frame 211. Rolling ball rods 213 are rotatably connected to the inner wall of the connecting frame 204 and the inner wall of the V-shaped frame 211. A telescopic rod 210 is fixedly connected to the outer surface of the support frame 208. A connecting plate 206 is fixedly connected to the telescopic end of the telescopic rod 210. Nuts 214 are threadedly connected to the outer surface of each rolling ball rod 213 and the outer surface of the connecting plate 206. The outer surface of each nut 214 is in contact with the outer surface of the U-shaped plate 205. The outer surface of the brake disc fixing body 1 is fixedly connected to the outer surface of the U-shaped plate 205.

[0027] Example 2

[0028] Please see Figure 1-5 Each rolling cue stick 213 and the connecting plate 206 are fitted with a gasket 6 on their outer surfaces. The outer surface of each gasket 6 is in contact with the outer surface of the U-shaped plate 205. The gasket 6 can increase the lubrication of the connection between the rolling cue stick 213 and the connecting plate 206, and prevent the rolling cue stick 213 and the connecting plate 206 from slipping during use.

[0029] Two reinforcing rings 5 ​​are fixedly connected to the outer surface of the telescopic rod 210. The outer surface of each reinforcing ring 5 is fixedly connected to the outer surface of the support frame 208. The reinforcing rings 5 ​​can fix the telescopic rod 210 and prevent the telescopic rod 210 from shaking during use.

[0030] The inner wall of the connecting plate 201 and the inner wall of the base plate 209 are both provided with two threaded holes 4. The outer surface of the connecting plate 206 is rotatably connected to the inner wall of the U-shaped plate 205. Through the threaded holes 4, the connecting plate 201 and the base plate 209 can be connected to the car body to avoid the problem of shaking of the connecting plate 201 and the base plate 209 during use.

[0031] A fixing ring 3 is fixedly connected to the outer surface of the brake disc fixing body 1. The outer surface of the fixing ring 3 is fixedly connected to the outer surface of the U-shaped plate 205. The fixing ring 3 can be used to reinforce the connection between the brake disc fixing body 1 and the U-shaped plate 205, so as to prevent cracks from appearing in the U-shaped plate 205 during use, which would affect the performance of the U-shaped plate 205.

[0032] Each fixed base 207 has a fixed frame 7 fixedly connected to its outer surface. The bottom surface of each fixed frame 7 is fixedly connected to the upper surface of the V-shaped frame 211. The fixed frame 7 can be used to fix the fixed base 207 and prevent the fixed base 207 from moving during use.

[0033] Example 3

[0034] The working principle of this utility model is as follows: When using this device, the brake disc fixing body 1 is connected and fixed to the wheel hub, and the connecting plate 201 and the base plate 209 are connected to the vehicle frame. During the movement of the car, it will vibrate up and down. The force generated by the vibration will act on the brake disc fixing body 1. The vibration of the brake disc fixing body 1 will drive the U-shaped plate 205 to vibrate up and down. Since the U-shaped plate 205 is connected to the connecting frame 204 and the V-shaped frame 211 respectively through the rolling ball 213 and the nut 214, and since the rolling ball 213 is rolledly connected to the connecting frame 204 and the V-shaped frame 211 respectively, the V-shaped frame 211 and the connecting frame 204 will move within a certain range. The movement of the connecting frame 204 and the V-shaped frame 211 drives the shock absorber in the shock absorber 203 to move through the connecting rod 212, the fixing seat 207 and the connecting... Under the support of the connecting plate 201, the shock absorber 203 is stretched around the axis of the connecting rod 212 to achieve shock absorption during vehicle vibration. As the vehicle continuously adjusts the position of the wheel hub during movement, the U-shaped plate 205 can be continuously adjusted in position through the telescopic relationship between the connecting plate 206 and the telescopic rod 210, thereby increasing the strength of the U-shaped plate 205. By adjusting the position of the U-shaped plate 205, the position of the brake disc fixing body 1 is adjusted, thereby improving the performance of the device. The rear suspension bracket is made of high-strength alloy steel or titanium alloy, which has high tensile strength and corrosion resistance. The tensile strength of alloy steel can reach more than 1000MPa, while titanium alloy has lighter weight and excellent fatigue performance. The surface of the material can also be treated with surface coating technology to further improve wear resistance and corrosion resistance.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
