The cylinder body of the first hanging oil cylinder be connected with one end of hanger bracket length direction, cylinder body and the hanger bracket length of the second hanging oil cylinder
The oil-in of the other end connection in direction, the first hanging oil cylinder and the second hanging oil cylinder is in parallel, and the first described counter-jib sets
Put in the bottom of the first hanging oil cylinder short transverse, its one end is connected on hanger bracket, and the other end is connected in the first vehicle bridge,
The second described counter-jib is arranged on the bottom of the second hanging oil cylinder short transverse, and its one end is connected on hanger bracket, and another
End is connected in the second vehicle bridge.
In a specific embodiment of the present invention, the first described hanging oil cylinder and the second hanging oil cylinder adopt oil gas
Suspension type suspension.
In another specific embodiment of the present invention, the structure of the first described vehicle bridge and the second vehicle bridge is identical,
Using the one kind in drive axle, braking axle or follow-up bridge.
In another specific embodiment of the present invention, the first described vehicle bridge and the second vehicle bridge adopt drive axle and system
Both dynamic bridges are combined.
In another specific embodiment of the present invention, described the first vehicle bridge and the back-to-back setting of the second vehicle bridge.
In an also specific embodiment of the present invention, the first wheel assembly, institute in the first described vehicle bridge, are equipped
The second wheel assembly is equipped in the second vehicle bridge stated.
The present invention compared with prior art, is had an advantageous effect in that as a result of said structure：By arranging two groups
Vehicle bridge, can make bearing capacity double, and stability is also improved；The steering or non-steering of whole bridge can be realized
Function；Overall structure is simply compact, it is easy to accomplish.
