The specific embodiment
Referring to Fig. 1 ~ Fig. 4, the utility model relates to a kind of link-type integral shaft steering hardware, and it comprises main hinge axle 3, turns to oil cylinder rear support 10 and adapter plate 12; Saidly turn to oil cylinder rear support 10 12 welding are arranged at crossbeam 14 bottoms with adapter plate, adapter plate 12 is positioned at the rear that turns to oil cylinder rear support 10, said turn to be equipped with on the oil cylinder rear support 10 turn to oil cylinder 11; The said cylinder body that turns to oil cylinder 11 through bearing pin with turn to oil cylinder rear support 10 to be rotationally connected, welding is provided with gusset piece 13 on the said adapter plate 12, is provided with stub bottom plate 15 through bolt on the said gusset piece 13; Said stub bottom plate 15 1 ends offer through hole, and the through hole top is provided with center 8, and center 8 is positioned at stub bottom plate 15 tops; Be provided with copper sheathing 4 in the said center 8; Said main hinge axle 3 hypomeres are plugged in the copper sheathing 4, and in the through hole of the lower end of main hinge axle 3 insertion stub bottom plate 15, the periphery wall of said center 8 is provided with deflecting plate 1 and following deflecting plate 9; The said deflecting plate 1 of going up all has two with following deflecting plate 9; Said two last deflecting plates 1 and two following deflecting plates 9 are arranged in parallel up and down, and said two upward are connected through guide pin bushing 5 between the deflecting plate 1, and said guide pin bushing 5 inboards are provided with bearing pin I6; Said bearing pin I6 is connected with rear pull bar 16; Said two upward also are provided with dividing plate 2 between the deflecting plate 1, are connected with bearing pin II7 between said two following deflecting plates 6, and the said rod end of oil cylinder 11 that turns to is connected with bearing pin II7.
The said oil cylinder 11 that turns to has two, and said two turn to oil cylinder 11 to be symmetrically arranged in adapter plate 12 both sides.
The saddle of tractor truck and superimposed trailer gooseneck rotating disk link together through the traction deck; When tractor truck is turned; Saddle and gooseneck rotating disk also can rotate thereupon, and gooseneck fluid-link steering oil cylinder couples together through bearing pin and gooseneck rotating disk, i.e. gooseneck fluid-link steering oil cylinder is realized stretching motion with one; Realize compression movement for one; And turn to oil cylinder to be cross-linked through hydraulic tubing and gooseneck fluid-link steering oil cylinder, cause the motion that turns to oil cylinder and the motion of gooseneck fluid-link steering oil cylinder to be consistent, thereby make deflecting plate turn over an angle.Be connected with the subframe assembly through pull bar and go up deflecting plate; Subframe assembly one side supports with revolution and welds, and one side welds with hitch, when last deflecting plate turns over an angle; Through the effect of pull bar, make revolution support and hitch also turn over an angle.When turning to, the line of centers of all tire is met at a bit, can effectively reduce Tyte Wear through the size that designs each subframe assembly.
