The connecting plate 7 carries out small range rotation, driving wheel assembly 61 and auxiliary wheel assembly 62 around connection pin shaft 9
It can freely be floated up and down according to road conditions or stress condition progress.
Fork truck when driving, driving wheel assembly 61 and assist wheel assembly 62 under the action of the spring buffer mechanism with two
Preceding wheel assembly 4 adapts to ground together, and vehicle frame 5 keeps stable state.For the validity for guaranteeing systems stabilisation, can according to driving wheel and
The stress condition of wheel assembly is assisted to match suitable spring 11.Simultaneously to guarantee that spring 11 works always, need to apply it
Certain pretightning force.In order to guarantee that spring being capable of Free Compression, it is necessary to assure retain between adjustment jacking block 12 and spring base certain
Distance S, as shown in Figure 3, and the road conditions that can be worked according to fork truck of the size of S value and load be adjusted, and operating condition is good
In the case of S value can be smaller because fork truck float displacement it is relatively small.It is on the contrary then can be larger.The adjusting of the gap S
Range is 10~15mm.When fork truck flat level road when driving, 4 wheels are in same level, since fork truck does not have
There is floating, this body stabilization system will not work.
When fork truck is when bumpy road works, this body stabilization system will generate effect.Such as drive 61 side of wheel assembly
Low-lying road surface is encountered, the center of gravity of vehicle body will be offset to this side at this time, and bigger gravity will be pressed on spring 11, give and drive
The bigger pressure of driving wheel assembly 61, can produce bigger driving force, enable fork truck normally travel.If without this stability series
System, other three wheels have formed a plane, and driving force will be detached from ground reduces driving force, cause tyre slip cannot
Normally travel.62 side of wheel assembly is such as assisted to encounter low-lying road surface, since spring 11 itself has pretightning force, spring will at this time
It opens, gives auxiliary wheel reaction force, so that auxiliary wheel is contacted ground and generate contact force, tilt vehicle body stabilization will not.In this way
Driving wheel and auxiliary wheel can be made all in stress, to avoid single tire force always, increase tyre life.
When fork truck is during zig zag, this body stabilization system can also generate effect.Such as to drive during wheel assembly 61 is
Heart turning, due to that can generate centrifugal force when turning speed is very fast, auxiliary wheel side gravity reduces even can be liftoff, increases this stabilization
After system, auxiliary wheel can be made to be permanently connected to ground by the reaction force of compressed spring, on the one hand share the pressure of driving wheel
On the other hand load prevents fork truck from tumbling.
The above content not makes any form of restriction the structure, shape of the utility model.It is all practical according to this
Novel technical spirit
Any simple modification, equivalent change and modification to the above embodiments still fall within the utility model technology
In the range of scheme.
