Embodiment
Below in conjunction with the accompanying drawings, the technical scheme in the utility model is carried out clearly, intactly to illustrate, described embodiment
A part only of the present utility model, based on the utility model main points in the utility model, those skilled in the art are not doing
Go out under the premise of creative work the every other utility model obtained to create, belong to the scope of the utility model protection.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of sealing drag-link joint assembly of the present embodiment include ball pin 1,
Dust cover 2, dust cover collar 3, joint 4, ball seat 5, end cap 6 and hexagon slotted nut 7.The dust cover 2 of the present embodiment is arranged on
Around the middle part of ball pin 1, the bottom of ball pin 1 is provided with ball seat 5, and the bottom of ball seat 5 is provided with end cap 6.
The ball pin 1 of the present embodiment is made up of spheroid 11, bucking ladder 12 and cone 13.Spheroid 11 is located at the bottom of ball pin 1,
Bucking ladder 12 is located at the middle part of ball pin 1, and cone 13 is located at the top of ball pin, and spheroid 11 is arranged in the cavity volume of ball seat 5, bucking ladder
12 be inverted trapezoidal, and bottom is small end, and top is big end, and the small end of bucking ladder 12 is connected with the top of spheroid 11.The cone of the present embodiment
The bottom of body 13 is the big end of cone, and top is cone small end, offers threaded joints in the upper end of cone 13, is connected by screw thread
Socket part is locked by hexagon slotted nut 7；Cone 13 and the arm taper hole of steering arm 8 are connected.The big end of bucking ladder 12 with
It is provided with cylinder step 14 between the big end of cone of cone 13, circular arc between the big end of cone of the upper end and cone 13 of cylinder step 14
Transition.
The upper end of the dust cover 2 of the present embodiment is held greatly installed in cone 13, and the lower end of dust cover 2 is through cone 13 and trapezoidal
