As shown from the above technical solution, the utility model adjusts the decrement of lower link spring by adjustment bolt, so that
Realize the adjustment to driving wheel load；The impact on road surface is absorbed by lower link spring and auxiliary wheel spring, driving is improved
The driver comfort of member.
Brief description of the drawings
Fig. 1 is the structural representation of prior art；
Fig. 2 is structural representation of the present utility model；
Fig. 3 is scheme of installation of the present utility model.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
A kind of reach truck drive axle as shown in Figure 2 and Figure 3, including drive wheel mechanism 7 and auxiliary wheel mechanism 15, drive
The upper end pin-and-hole of driving wheel mechanism 7 is connected by driving wheel bearing pin 8 with the left end pin-and-hole of upper connecting rod 9, and the right-hand member pin-and-hole of upper connecting rod 9 leads to
Cross upper connecting rod bearing pin 10 with vehicle frame 5 to be connected, the lower end of drive wheel mechanism 7 passes through lower link bearing pin 11 and the left end pin of lower link 14
Hole is connected, and the lower link spring 3 of both connections, a left side for auxiliary wheel mechanism 15 are additionally provided between the left end and vehicle frame 5 of lower link 14
End pin-and-hole is connected by auxiliary wheel bearing pin 1 with the middle pin-and-hole and vehicle frame 5 of lower link 14, and the right-hand member of auxiliary wheel mechanism 15 passes through auxiliary
Wheel spring 16 is helped to be connected with the right-hand member of lower link 14.
Further, the lower end of lower link spring 3 is connected with the left end of lower link 14, and the upper end of lower link spring 3 passes through
Lower link spring base 13 is connected with adjustment bolt 4, and adjustment bolt 4 is arranged on the screwed hole of adjustment bolt installing plate 2, and is passed through
Locking nut 12 is locked, and adjustment bolt installing plate 2 is welded on vehicle frame 5.
Operation principle and the course of work of the present utility model are as follows：
First, driving wheel load adjustment：
The decrement of lower link spring 3 is adjusted by the adjustment bolt 4 on adjustment bolt installing plate 2, under change
Rod spring 3 is to the pressure of lower link 14, so as to adjust driving wheel load；When the fork truck that moves forward works in prevailing roadway, the inverse time
Pin rotates adjustment bolt 4, reduces the decrement of lower link spring 3, reduces driving wheel load, improves the driving wheel life-span；Work as reach
When fork truck works on freezer environment road surface, the adjustment bolt that turns clockwise 4, the decrement of increase lower link spring 3, increase driving
Load is taken turns, driving wheel slippage problems are solved.
2nd, road shocks are absorbed：
Auxiliary wheel spring 16 can absorb the impact that road surface is transmitted by auxiliary wheel, and lower link spring 3 can absorb road surface and pass through
The impact of driving wheel transmission, the road shocks so passed on vehicle frame are smaller, can improve driver comfort.
The beneficial effects of the utility model are：The reach truck drive axle not only meets the function of driving and support,
Driving wheel load can also be adjusted, to adapt to different road environments, the impact of road surface transmission can be absorbed, relaxing for driving is improved
Adaptive.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, on the premise of the utility model design spirit is not departed from, and those of ordinary skill in the art are to this
Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of the utility model claims determination
In the range of.
