[0002] In the automotive field, the front double axle generally adopts an independent leaf spring structure. The two sets of axles are connected to the frame through two sets of leaf springs respectively. When the vehicle is overloaded, the leaf springs not only bear the load-bearing capacity, but also need to bear the lateral force when passing over potholes. As a result, when the overloaded vehicle is driving in a bad situation or on a pothole-prone road, the existing front double axle structure will have the problem of large impact of the vehicle's unbalanced load on the load-bearing system, which will cause the leaf springs, axles, and tires to be subjected to uneven force instantly, resulting in leaf spring fatigue fracture, tire damage, etc., posing a safety hazard.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1

[0025] In this embodiment, if Figure 1-Figure 7 As shown, a through balanced double steering front axle suspension structure includes a balanced suspension assembly 2 fixedly mounted on a vehicle frame 1. The balanced suspension assembly 2 allows the vehicle tires to stay on the ground, exerts the load-bearing capacity of the front double axles and improves the anti-seismic capacity of the front double axles. A first bridge 3 and a second bridge 4 are arranged below the vehicle frame 1. The balanced suspension assembly 2 is connected to the first bridge 3 and the second bridge 4 through a thrust rod 5. Through the through balanced double steering front axle suspension structure, when the vehicle is driving on a bad or bumpy road, the balanced suspension assembly 2 can drive the first bridge 3 and the second bridge 4 to evenly load the load, thereby ensuring that the tires always keep in contact with the ground, thereby improving the vehicle's usability. Reliability and comfort, the thrust rod 5 includes a group of upper eight-shaped structure thrust rods and a group of lower eight-shaped structure thrust rods, one end of the upper eight-shaped structure thrust rod and the lower eight-shaped structure thrust rod are hingedly connected to the balance suspension assembly 2 through a pin shaft, one end of the upper eight-shaped structure thrust rod and the lower eight-shaped structure thrust rod are hingedly connected to the first bridge 3 through a pin shaft, and the other end of the upper eight-shaped structure thrust rod and the lower eight-shaped structure thrust rod are hingedly connected to the second bridge 4. The thrust rod 5 can be swung up and down and left and right in a small amplitude to reduce the impact of the vehicle tire and the road surface, withstand the lateral force when passing over a pothole road, and effectively control the left and right displacement of the vehicle axle during driving;

[0026] Among them Figure 3 As shown, bearing hubs 6 are arranged on both sides of the balancing suspension assembly 2. The function of the bearing hubs 6 is to bear the weight and provide precise guidance for the rotation of the wheel hub. A bearing hub end cover 7 is arranged on one side of the bearing hub 6. The bearing hub 6 is fixedly connected to the balancing suspension assembly 2 through the bearing hub end cover 7 and fixing bolts, which is convenient for fixing, increases the safety and stability of the structure, and has good practicality.

[0027] Among them Figure 5 and Figure 6As shown, the upper eight-shaped structure thrust rod includes a first structure thrust rod 50 and a second structure thrust rod 51, and the lower eight-shaped structure thrust rod includes a third structure thrust rod 52 and a fourth structure thrust rod 53. The upper eight-shaped structure thrust rod and the lower eight-shaped structure thrust rod are arranged in an eight-shaped cross shape, which is convenient for realizing the up and down swinging of the two ends of the leaf spring 9, adapting to different road conditions, and sharing the load together;

[0028] Among them Figure 2 and Figure 4 As shown, the first bridge 3 and the second bridge 4 are symmetrically mounted with a skateboard seat 8, and a leaf spring 9 is movably arranged between the two skateboard seats 8. When the road surface exerts an impact force on the vehicle tire, the leaf spring 9 is deformed, thereby playing a role of buffering and vibration reduction;

[0029] Among them Figure 2 As shown, the leaf spring 9 includes a left leaf spring 91 and a right leaf spring 92. The left leaf spring 91 is connected between the left end of the first bridge 3 and the left end of the second bridge 4, and the right leaf spring 92 is connected between the right end of the first bridge 3 and the right end of the second bridge 4. The balancing suspension assembly 2 is fixedly connected to the leaf spring 9, and the left end of the balancing suspension assembly 2 is fixedly connected to the middle of the left leaf spring 91, and the right end of the balancing suspension assembly 2 is fixedly connected to the middle of the right leaf spring 92. When the vehicle is traveling on an undulating road, this structure can prevent the axle from being suspended, maximize the load-bearing capacity of the front double axle, and improve the impact resistance.

[0030] Example 2

[0031] The difference from Example 1 is that Figure 2 and Figure 7 As shown, a leaf spring pressure plate 10 is provided at the lower end of the leaf spring 9, and the leaf spring pressure plate 10 is fixedly connected to the bearing hubs 6 at both ends of the balance suspension assembly 2 through U-bolts 11 and U-bolt locking nuts 12. The leaf spring 9 realizes the up and down swing of the front and rear ends through the balance suspension assembly 2, and shares the load together, and follows the first bridge 3 and the second bridge 4 to adapt to the ups and downs of the road conditions;

[0032] Among them Figure 4 As shown, the bearing hub 6 is fixedly connected to the leaf spring 9, and the middle parts of the left leaf spring 91 and the right leaf spring 92 are fixedly connected to the bearing hubs 6 at both ends of the balanced suspension assembly 2. This structure can improve the impact resistance and maximize the load-bearing capacity of the front double axle.

[0033] During use, when driving on a bumpy road, the road surface of the first bridge 3 is convex and the road surface of the second bridge 4 is concave, the first bridge 3 drives one side of the leaf spring 9 to move upward, and the second bridge 4 drives the other side of the leaf spring 9 to move downward, so that the through-balanced double-steering front axle suspension structure works together, thereby making the first bridge 3 and the second bridge 4 evenly loaded, ensuring that the tires are always in contact with the ground; when the road surface of the first bridge 3 is concave and the road surface of the second bridge 4 is convex, the whole structure moves in the opposite direction, achieving the effect of the front double bridges sharing the load together, and having good practicality.

[0034] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
