Further, the locking device includes the adjusting nut contradicted with integral hermetic formula bearing outer end, adjusting nut
Left side be provided with locking nut, lock washer is provided between adjusting nut and locking nut.
Further, the integral hermetic formula bearing also includes two groups of rolling elements, and integral type is set on the inside of two groups of rolling elements
Inner ring, two groups of rolling elements outsides are respectively arranged with outer ring, positioning sleeve are set in the middle part of the inner ring.
Further, the adjusting nut is along the circumferential direction evenly arranged with the alignment pin of predetermined number, and passes through positioning
Pin is connected with lock washer.
Further, coordinated inside the thread segment between positioning end cap with thread connecting mode, the positioning end cap
End and locking device on the outside of it is inconsistent.
The beneficial effects of the utility model are：
The utility model carries out structure design to the spindle nose and part of bridge tube main body, and one is set at the linkage section of spindle nose
Sealed bearing, integral hermetic formula bearing both ends set oil seal, and existing oil-sealing measures are to set oil sealing in bridge tube main body
Skeleton, the difficulty of processing and precision of bridge tube main body are added, the design of the integral hermetic formula bearing containing oil seal is to bridge tube main body
Processing request it is low, and need to only fill long-acting lubricating grease in advance at oil sealing, it is not necessary to which often dismounting hub system is safeguarded
Maintenance, makes easy to maintenance quick, reduces maintenance cost；In assembling the locking device for including adjusting nut and locking nut
Spindle nose end is fitted into positioning end cap, fastening force is reached technical requirements, without adjusting pretightning force repeatedly, vehicle bridge is integrally tied
Structure is more stable, security performance is higher, has reached purpose non-maintaining for a long time.
To sum up, the non-maintaining semitrailer axle assembly is simple and compact for structure, bearing pretension function is more preferable, safe and reliable
Property is higher, has reached long-term non-maintaining purpose.
