Together, after the positioning key on locking piece aligns with the positioning spline on steering column on mandrel, positioning screw is screwed；Positioning screw
Depart from the gap between lid and base on clock spring, now positioning release, base and the steering column frame of clock spring are consolidated
Fixed, the keyway on the mandrel of locking piece and steering column is fixed, and upper lid and locking piece can rotate with tubing string mandrel；
（3）When positioning screw is locked, the locking piece of location tray and clock spring on steering column mandrel coordinates, clock
Lateral clearance between the upper lid and base of spring is 1.6mm, axial clearance 3mm, then installation direction disk；
（4）By car steering wheel wire harness to inserting in clock spring top wire harness to interface, during by body harness to inserting in
Clock spring bottom wire harness makes car steering wheel wire harness turn on to form path with body harness by clock spring interface.When
Role is equivalent to connector in the entire system for clock spring, and when making steering wheel ± 3 circle of rotation, loop turns on.
The floated clock spring of the present invention is after entrucking, and upper lid does not contact with base, it is ensured that flat cable is not by clock
Spring housing extruding, friction, and upper lid does not also wear with base, reduces noise caused by phase mutual friction between housing, has
Effect improves housing endurance quality and life of product.
