The specific embodiment
In order to make those skilled in the art person understand better the scheme of the embodiment of the present invention, below in conjunction with drawings and embodiments, the embodiment of the present invention is described in further detail.
for existing multi-axle steering system vehicle at full load, front steering axle load is less, main load concentrates on assisted diversion bridge and rear driving axle, the load skewness, can't reach the situation that more satisfactory load distributes, the utility model provides a kind of multi-axle steering system load to adjust structure, adjust in structure in this load, the assisted diversion bridge is connected with described vehicle frame by compound suspension frame, and the load of carrying levelling valve sensing rear driving axle by the sense that is arranged on vehicle frame, height according to the described compound suspension frame of load control of rear driving axle, thereby can regulate the load of assisted diversion bridge, the car load axle load can better be distributed.
As shown in Figure 1, be the front view that the utility model embodiment multi-axle steering system load is adjusted structure; Fig. 2 is the birds-eye view that this multi-axle steering system load is adjusted structure.
In this embodiment, described multi-axle steering system load is adjusted structure, comprising: vehicle frame 1, levelling valve 6 is carried in front steering axle 12, assisted diversion bridge 9, rear driving axle 7 and sense.
Assisted diversion bridge 9 is connected with vehicle frame 1 by compound suspension frame, and described compound suspension frame comprises: leaf spring 10 and flexible adjustment device 15.Leaf spring 10 two ends are connected with vehicle frame 1 by the first hanger 3 respectively, and flexible adjustment device 15 is between leaf spring 10 and vehicle frame 1.
Sense is carried a levelling valve 6 and is arranged on vehicle frame 1 and near assisted diversion bridge 9, is used for the load of sensing rear driving axle 7, and according to the height of 7 described compound suspension frames of load control of described rear driving axle, thereby the load of regulating assisted diversion bridge 9.
