In other embodiments, the hinge points of the first and second coil springs and the axle 4 may be staggered along the axial direction of the axle, and the first and second coil springs are hinged at different positions on the axle, so that the central axes of the first and second coil springs are different, and an included angle is formed between the central axes of the first and second coil springs.
When the axle 4 moves upwards relative to the frame 1, the first spiral spring and the second spiral spring are compressed and contracted, the first spiral spring and the second spiral spring swing downwards around the same angle with the hinging point of the axle 4 respectively, and the angle a of a plane formed between the first spiral spring and the second spiral spring is increased; when the axle 4 moves downwards relative to the frame 1, the first and second spiral springs are stretched, the first and second spiral springs swing upwards by the same angle around the hinge point with the axle 4, and the degree of a plane included angle a formed between the first and second spiral springs is reduced. The angle of the plane included angle a can be changed when the axle jumps up and down, and the size of the plane included angle a is 0-90 degrees. When the vehicle is in a normal running state, the axle 4 of the vehicle receives an upward acting force F N Spring force F of two helical springs 2 obliquely downward S The axle is in a balanced state, and the stress analysis shows that: the sum of the components of the two helical springs in the vertical direction and the force F N Equal in size, i.e. 2.F S ·cos（a/2）=F N Let coil spring's original length be L1, the instantaneous length after loading be L0, elasticity coefficient be K, can obtain from this:

wherein, (L1-L0) is the deformation amount of the coil spring, 2k·cos (a/2) is a constant term of the deformation amount of the coil spring, which is the suspension stiffness C of the vehicle, i.e., c=2k·cos (a/2).
The damping elements of the suspension system are air dampers, each pair of elastic elements corresponds to one damper, each damper comprises a cylinder body 5, the cylinder body 5 is fixedly arranged on the frame 1, a piston 7 is assembled in the cylinder body 5 in an up-down guiding manner, the piston 7 comprises an upper piston plate and a lower piston plate, the upper piston plate and the cylinder body 5 form a sealed upper cavity, the lower piston plate and the cylinder body form a sealed lower cavity, and sealing rings 8 are arranged on the upper piston plate and the lower piston plate, so that the tightness of the damper is ensured; the sealing ring 8 is provided with lubricating oil, so that the resistance of the piston in movement is reduced. The upper piston plate and the lower piston plate are fixedly connected together through a connecting rod, the upper piston plate, the lower piston plate and the cylinder body enclose a hollow cavity, a side opening is arranged on the side wall of the hollow cavity, a deflector rod 6 is fixedly arranged on the axle 4, and the deflector rod 6 penetrates into the hollow cavity from the side opening and is connected with the piston 7 along the radial direction of the piston 7; when the axle moves up and down, the deflector rod moves up and down along with the axle and pushes the piston 7 to move up and down, when the piston 7 moves up, air in the upper cavity is pressurized, air in the lower cavity is pulled, and the upper piston plate and the lower piston plate are respectively subjected to downward acting force; conversely, air in the upper cavity is pulled, air in the lower cavity is pressurized, and the upper piston plate and the lower piston plate are respectively subjected to upward forces.

Wherein: p1 is the sum of the pressures of the upper cavity and the lower cavity of the cylinder body, P0 is the external atmospheric pressure, and S is the area of the piston plate; the change speed of P1 and P0 depends on the change speed of the volume of the damper, when the axle jumps upwards or downwards rapidly, the change speed of the volume of air in the damper is increased rapidly, the damping force F is increased rapidly, the rapid damping vibration quantity can be realized, and the running stability and riding comfort of the vehicle are ensured.
When the vehicle passes through the concave pavement, the axle 4 can jump downwards relative to the frame 1, the plane included angle a between the first spiral spring and the second spiral spring can be reduced, the cos (a/2) value is increased, and the suspension rigidity C of the vehicle is further increased; along with the continuous increase of the jumping-down amount of the axle 4, the suspension rigidity C of the vehicle is also continuously increased, so that the jumping-down amount of the vehicle when passing through the concave road surface can be reduced, and the stability of the vehicle body is ensured. Meanwhile, as the vehicle axle continuously jumps down, the damping force generated by the damper is rapidly increased along with the increase of the jumping-down speed, when the vehicle encounters a large concave road surface, the damper can generate larger damping force to rapidly attenuate the vehicle vibration caused by the excitation of the road surface, and the running smoothness and riding comfort of the vehicle are improved.
When the vehicle passes through the raised pavement, the axle 4 can jump upwards relative to the frame 1, the plane included angle a between the first spiral spring and the second spiral spring is increased, the cos (a/2) value is reduced, the vehicle suspension rigidity C is reduced, and the axle 4 jumps upwards relative to the frame rapidly, so that the stability of the frame 1 is ensured. The damping force generated by the damper is also increased sharply when the axle jumps up rapidly, the axle does not generate great vibration, the vibration condition of the vehicle when passing through the raised pavement is weakened, and the running smoothness and riding comfort of the vehicle are improved.
By combining the two conditions, when the vehicle passes through the concave-convex road surface, the elastic element realizes real-time adjustment of the rigidity of the suspension along with the road condition, the damping element can quickly attenuate the vibration of the vehicle axle caused by road surface excitation, and the suspension system improves the running smoothness and riding comfort of the vehicle and has great use value.
