Specific embodiment
To keep the purposes, technical schemes and advantages of the application implementation clearer, below in conjunction in the embodiment of the present application
Attached drawing, technical solutions in the embodiments of the present application is further described in more detail.
In the description of the present application, term " center ", " longitudinal direction ", " transverse direction ", "front", "rear", "left", "right", "vertical",
The orientation or positional relationship of the instructions such as "horizontal", "top", "bottom", "inner", "outside" is that orientation based on the figure or position are closed
System is merely for convenience of description the application and simplifies description, rather than the device or element of indication or suggestion meaning must have
Specific orientation is constructed and operated in a specific orientation, therefore should not be understood as the limitation to the application protection scope.
As shown in Figure 1, the hydrocoupling wheel hub of the application includes driving section 1, reference portion 4 and measurement sensor 5.
The inner hole of driving section 1 includes the first aperture section 2 and the second aperture section 3, and the first aperture section 2 with installation axle 20 for matching
It closes, the diameter of the second aperture section 3 is greater than the diameter of the first aperture section 2, the sky between the inner hole and installation axle 20 of the second aperture section 3
Between for install reference portion 4；Reference portion 4 is cyclic structure, and its outer ring surface 42 with diameter value consecutive variations, reference portion 4
The gap for being installed in installation axle 20 and being located between the second aperture section 3 and installation axle 20；Measurement sensor 5 is arranged in the second hole
On the side wall of diameter section 3, for detect measurement sensor 5 and referring to portion 4 outer ring surface 42 between spacing.Due to reference portion 4
Outer ring surface is diameter value consecutive variations, therefore measurement sensor 5 can relatively rotate in installation axle 20 and driving section 1
In the case of measure distance values have variation, therefore, it is determined that installation axle 20 is relatively rotated with driving section 1.
