, arranging through slots on the positioning sleeve, and inserting the positioning sleeve into the positioning through holes in clearance fit when external force is applied to connect the two end faces of the through slots.
, each set of bolt fastener comprises two single-head bolts and threaded hole bases, wherein two threaded holes are formed in the threaded hole bases and correspond to the two single-head bolts .
, positioning blind holes are further formed in the positioning mounting pair, and positioning pins are embedded in the positioning blind holes in an interference fit mode.
And , arranging the single-head bolts two by two symmetrically about the same central point.
And , locating the blind locating hole and the locating pin at the central point.
And , arranging a process threaded hole on the outer end face of the positioning pin.
Has the advantages that: according to the invention, the positioning sleeve arranged between the screw rod and the positioning through hole is matched with the positioning pin, so that the positioning of the antenna bracket and the bogie on the connecting plane is realized, the positioning sleeve and the positioning pin bear the shearing force under various working conditions, and the situation that the single-head bolt is subjected to the transverse shearing force under various working conditions of the bogie is avoided.
Besides, when loads at all positions on the positioning mounting pair are uneven, the two single-head bolts on the same threaded hole base mutually exert acting force through the threaded hole bases, so that the difference of the loads borne by the two single-head bolts is reduced, and the load borne by the single-head bolt is prevented from being overlarge.
Meanwhile, compared with the prior art that the single-head bolt is screwed into the threaded hole of the bogie positioning plate, the length of the single-head bolt is increased, so that the elastic deformation of the single-head bolt is increased, and the axial stress state of the single-head bolt is improved.
