The spring buffer mechanisms above the second spring seat 2 and the third spring seat 3 have the same structure as the spring buffer mechanism on the first spring seat 1. The spring 11 is a cylindrical helical compression spring.
Referring to fig. 6 to 8, the connecting plate 7 is an integral steel casting, the connecting plate 7 includes an upper horizontal plate 71 in a horizontal direction, a lower horizontal plate 73 in a horizontal direction of a neutral plate 72 in a vertical direction, a first mounting hole 711 is formed in the upper horizontal plate 71, the driving wheel assembly 61 is mounted in the first mounting hole 711, and the first spring seat 1 is located on an upper plane of the upper horizontal plate 71. The neutral plate 72 is provided with a first weight-reducing hole 721 and a pin hole 722, the pin hole 722 is positioned at the lower end of the neutral plate 72, a shaft sleeve 8 is arranged in the pin hole 722, and a connecting pin 9 is arranged in the shaft sleeve 8. The lower cross plate 73 is provided with a second mounting hole 731, the second mounting hole 731 is used for mounting the auxiliary wheel assembly 62, the second spring seat 2 and the third spring seat 3 are located on the upper plane of the lower cross plate 73 and located on two sides of the second mounting hole 731, and the lower cross plate 73 is provided with a second weight reducing hole 732 and a third weight reducing hole 733.

The connecting plate 7 can rotate around the connecting pin shaft 9 in a small range, and the driving wheel assembly 61 and the auxiliary wheel assembly 62 can freely float up and down according to road conditions or stress conditions.
When the forklift runs, the driving wheel assembly 61 and the auxiliary wheel assembly 62 adapt to the ground together with the two front wheel assemblies 4 under the action of the spring buffer mechanism, and the frame 5 keeps a stable state. To ensure the effectiveness of the stabilizing system, a suitable spring 11 may be selected according to the stress conditions of the driving wheel and auxiliary wheel assembly. At the same time, a certain pre-tightening force needs to be applied to the spring 11 in order to ensure that the spring is always active. In order to ensure that the spring is able to compress freely, it must be ensured that a certain distance S remains between the adjustment top piece 12 and the spring seat, as shown in fig. 3, and the magnitude of the S value can be adjusted according to the road conditions and load on which the forklift works, and in the case of good working conditions the S value can be smaller, because the displacement of the forklift floating is relatively smaller. And conversely, the size can be larger. The adjustment range of the gap S is 10-15 mm. When the forklift runs on a flat horizontal road surface, 4 wheels are on the same horizontal plane, and the body stabilizing system cannot work because the forklift does not float.
The body stabilization system will function when the truck is operating on bumpy roads. If one side of the driving wheel assembly 61 encounters a low-lying road surface, the gravity center of the vehicle body is offset to the side, and the greater gravity is pressed on the spring 11, so that the driving wheel assembly 61 is given greater pressure, and greater driving force can be generated, so that the forklift can run normally. Without this stabilizing system, the other three wheels would have formed a plane and the driving force would disengage from the ground reducing the driving force, rendering the tire slip impossible to run normally. If one side of the auxiliary wheel assembly 62 encounters a low-lying road surface, the spring 11 is expanded due to the pretightening force of the spring, and the reaction force is given to the auxiliary wheel, so that the auxiliary wheel can contact the ground to generate contact force, and the vehicle body is stable and cannot incline. Therefore, the driving wheel and the auxiliary wheel can be always stressed, the stress of a single tire is avoided, and the service life of the tire is prolonged.
The body stabilization system also works when the truck is in a tight turn. If the driving wheel assembly 61 is used as the center for turning, the centrifugal force is generated when the turning speed is high, the gravity on one side of the auxiliary wheel is reduced, even the auxiliary wheel is separated from the ground, after the stabilizing system is added, the auxiliary wheel can always contact the ground through the reaction force of the compression spring, so that the pressure load of the driving wheel is shared on one hand, and the forklift is prevented from tipping on the other hand.
The above is not intended to limit the structure, shape, or any form of the present invention. Any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present invention still fall within the scope of the technical solution of the present invention.
