Description
Technical field
The utility model belongs to the improvement of autotruck or superimposed trailer suspension gear, particularly autotruck carrying bridge bont.
Background technology
Its maximum characteristics of autotruck that drive in 6 * 2 modes are on empty wagons or road surface when poor, and the tire of drive axle and traction deficiency often cause skidding easily, and promptly the propulsive effort deficiency should not be used on the little road surface of coefficient of road adhesion.The automobile of two in addition backs bridge construction is in cruising and turning process, and its wear on tyres is bigger than common 4 * 2 mode driven vehicles wearing and tearing, and resistance to motion is also bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of autotruck carrying bridge bont, can be under different load, load between reasonable distribution carrying bridge and the drive axle, when automobile is unloaded, to carry bridge and promote certain height, make in the unloaded long-distance running of automobile, reduce the wearing and tearing of motor tire, reduce oil consumption.When heavy duty, the carrying bridge is broken away from automatically, automobile is in the cruising state.Can improve crossing ability, the ride comfort of automobile on relatively poor road surface, propulsive effort can be given full play to.
The purpose of this utility model is achieved in that a kind of autotruck carrying bridge bont, comprise by steel spring and be installed in the drive axle on the vehicle frame and carry bridge, on vehicle frame, rotating shaft is installed by bearing seat, in rotating shaft, fixedly mounting lever lifting device, one end of lever lifting device and the piston rod of oil cylinder or cylinder are hinged, the articulated erecting by overhang of the other end of lever lifting device, the lower end of erecting by overhang is connecting the carrying bridge by connecting device, and the other end of oil cylinder or cylinder is hinged with the bearing that is installed on the cross member of frame.
When vehicle was unloaded, the piston of handling oil cylinder or cylinder promoted to be installed in the lever lifting device in the rotating shaft, mentions the carrying bridge by the connecting device of pivotally attached erecting by overhang lower end.Carry not load-bearing of bridge this moment, and automobile turns to very easily in the process of moving, thereby has reduced Tyte Wear, has also reduced oil consumption.When heavy duty need be put down the carrying bridge, handle oil cylinder or cylinder, piston rod is reclaimed spur the lever lifting device that is installed in the rotating shaft, and under the effect of carrying bridge gravity, the lever lift structure puts down the carrying bridge by the connecting device of erecting by overhang lower end, makes autotruck be in normal operating condition.The utility model makes the axle load of the carrying bridge of autotruck shift to drive axle, has improved the crossing ability of autotruck on relatively poor road surface significantly, has reduced the wearing and tearing of motor tire, and the propulsive effort of automobile can be given full play to.
