Bearing unit technical field.
Background technology
Compared with general bearing, bearing unit for saloon car wheel hub is the of a relatively high class bearing of technical sophistication degree.From
Since the hub-bearing unit of Aktiebolaget SKF's manufacture in 1938 comes out, hub-bearing unit is just always towards high loadability, structure
Compact, non-maintaining, high reliability and lightweight direction are developed.Initial failure requirement of the assembly plant to key components and parts is got over
Come stricter.The typical phenomenon of hub-bearing unit initial failure rocks to there is abnormal sound, wheel, and these phenomenons are all due to
Caused by the end-play of hub-bearing unit changes, therefore, shadow of the research end-play to bearing unit for saloon car wheel hub performance
Ring highly significant.
Hub-bearing unit end-play significantly affects the load distribution and displacement of Bearing inner and carried by interior contact
The fatigue life that lotus determines.In order to obtain longer fatigue life and improve torque rigidity, it is necessary to which hub-bearing unit is applied
Suitable axial preload, so that bearing works under negative end-play, the reasonability of the clearance directly influences hub spindle
The working life of bearing unit.When negative clearance is inadequate, hub-bearing unit under loaded state easy looseness and form vibration；When
When negative clearance is excessive, causes the contact stress of raceway excessive and produce early fatigue, both states to life-span of bearing not
Profit.Hub-bearing unit for realizing pretension using axle riveted, needs to ensure that bearing is in suitably original before pretension is implemented
End-play simultaneously effectively controls axial prefastening load.Lifetime of system when hub-bearing unit is in a suitable axially negative clearance
It is most long, but further increase (i.e. axial preload increases) with clearance is axially born, fatigue life reduces rapidly.Existing hub spindle
Bearing unit method for measuring axial clearance：Hub-bearing unit ring flange and base engagement, apply to cycle surface loading head and unload
Power is carried, the power applied just causes molding to stir inner side steel ball under certain moment of torsion, records now unloading force, for dress
The unloading force of car part, next can calculate hub-bearing unit axial load and end-play by programming.The inspection
Survey method can not realize on-line monitoring, and complex operation, it is impossible to be pinpointed the problems in time in vehicle traveling.
The content of the invention
