The design feature of the differential screwed mechanism of driving axis main flare nut of the present invention lies also in:
Press-fit sleeve in the described bottom tightening axle by sleeve stage clip, make described sleeve can tighten formation axial float on axle；
Press-fit spline pawl in the bottom of described rotary sleeve by spline pawl stage clip, make described spline pawl can form axle on rotary sleeve
To floating；Described splined shaft is to be fitted in described spline housing with top splined shaft stage clip and can form axial float in spline housing.
Being provided with core bar in described splined shaft, described splined shaft is with core bar as guide post；At described spline housing and rotary sleeve
Between the first needle bearing is set, between described rotary sleeve and splined shaft, be provided with the second needle bearing.
Arrange described sleeve and spline pawl to rotate for differential in the same direction.
Compared with the prior art, the present invention has the beneficial effect that:
1, the present invention arranges a pair gear engagement, is effectively incorporated on coaxial position by two power transfer lines, power transmission knot
Structure is simple；
2, the present invention can realize differential screwed, it is simple to adjusts tight condition in real time, makes locking nut screwing state suitable；
3, the present invention is i.e. applicable to tightening of locking nut that the master of different model subtracts by changing sleeve；
4, arranging torque sensor in being embodied as of the present invention, the real time detection signal of available torque sensor realizes closed loop control
System, and utilize detection signal to calculate acquisition pretightning force, it is achieved the detection of pretightning force.
