Fastening loop coil is screwed in plug screw and is pressed in cross-bar connector, there is straight-through grease nipple below plug screw, has the platform of protrusion in pin rod lower end
With frustum, ball stud is slipped with outer ring when frustum can prevent bulb from damaging；
Wherein the connecting rod of arthrodia bearing uses tapered structure, and welds together the boss simultaneously with tapered structure
It is assembled together with rocker arm assembly.End has thread section to connecting rod on it, and is constructed in the end thread section
There is radial perforation.
Further, it using hex nut, and is tightened in the end thread section according to the torque of regulation, thus and even
Bar, boss and rocker arm assembly are fixed together.
Further, to prevent hex nut from loosening, which includes clamp ring, split pin and latch segment.
The clamp ring is sleeved in a manner of it can surround end thread section rotation on the end of the connecting rod,
Further, at least one locking is provided between the inner circumferential side of the clamp ring and the hex nut
Block, latch segment is firmly clamped between the inner circumferential side of clamp ring and the corresponding peripheral side of hex nut, so that hexagonal
Nut cannot rotate.
Preferably, at least one second hole is also configured in clamp ring, fixed pin passes through the second hole top in clamp ring
It leans against on latch segment and by latch segment relative to the nut check, to be prevented more reliably hex nut relative to connecting rod
Rotation.It just has been able to prevent the opposite link rotatable of nut well by the latch segment being clamped between clamp ring and nut,
And by the way that the second hole and fixed pin is additionally arranged, then further ensure the locking effect of latch segment.
The length of pin rod screw thread is more than the length of protruding end column part, and the diameter of column part is more than the diameter of screw thread,
Two-sided tapered sleeve endoporus is that screw hole is screwed on pin rod, and the inner ring end that a pressure ring is pressed in arthrodia bearing is fixed in one end of two-sided tapered sleeve
Face.
The invention avoids scenes to process, and machining accuracy is low, easy tos produce clast, assembly cleannes are low, and efficiency of assembling is low
The problems such as, and realize easy to operate, easy to assembly, the advantages that precision is high, and cleannes are high.
