Toe-in value is adjusted, finally tightens the ＇ of locking nut 3.
Adjustment toe-in in the prior art has as a drawback that：
1st, when unclamping locking nut, direction is not easy to judge, often occur actual rotation direction and being intended to adjust it is in opposite direction
Situation；And because insert space limits, the limited angle once rotated, it is necessary to will when spanner, which rotates, encounters parts nearby
Spanner pulls down the cooperation for readjusting spanner and locking nut outer-hexagonal face, cause it is cumbersome, adjustment it is slower.
When the 2nd, adjusting prenex by professional equipment measurement, rotating drag link makes toe-in reach desired value, but is tightening locking
Need the operation of two spanners during nut, a spanner is stuck in motionless on drag link, and another is stuck on locking nut and tightened
Operation, often can drive drag link to rotate in rundown process, so that final toe-in value and the value for wishing to adjust are inclined
Difference.
3rd, when manual measurement adjustment is prenex, it is necessary to before locking nut unclamps with a certain distance from from locking nut end face
Make marks line on the screw thread of drag link, and measures the initial distance；After unclamping locking nut and then rotating drag link adjustment toe-in,
Locking nut is tightened again, and measures locking nut end face to the distance of mark line；The last prenex size actually adjusted is equal to just
Beginning distance and finally apart from its difference, it is larger that this adjustment operates comparatively laborious and error.
