The technical scheme is that：
A kind of automobile supports rear axle assy, including central siphon, spindle nose, connecting plate, brake and rear axle hub, it is characterised in that：Axle
The two ends of pipe are welded by connecting plate spindle nose, and brake is housed on spindle nose, and one end of spindle nose extends to brake outer end, extends
Rear axle hub is housed, rear axle hub is connected with brake by fixing bolt on to the spindle nose of brake outer end.
Shape is spaced on the rear axle hub and is provided with boss, bearing A wherein is installed on the spindle nose of side outside the boss, separately
Bearing B is installed on the spindle nose of side outside the boss, spacer is provided between bearing A and bearing B, spacer is distinguished by connection ring
It is connected with bearing A and bearing B.
Described bearing A and bearing B is respectively taper roll bearing, and the inner ring outside of bearing A and bearing B is respectively arranged with
Bearing draw-in groove.
Described spacer is diameter-changing body, and the two ends of spacer are respectively arranged with spacer draw-in groove, and spacer is with bearing A's and bearing B
Between inner ring from connection ring by with spacer draw-in groove and bearing draw-in groove with mutual clamping.
The outer ring side of described bearing A is provided with seal A, and the outer ring side of bearing B is provided with seal B.
Described seal A and seal B is respectively sealing ring.
Sealing ring is provided between described bearing B inner rings and spindle nose.
The beneficial effects of the present invention are：
The automobile supports rear axle assy simple structure, maintains easily, and compared to existing supporting back axle, eliminates main gearbox assembly,
Assembly weight is thus reduced, can meet by the connecting plate at central siphon two ends reduces the requirement of vehicle height.Pass through back axle simultaneously
Seal on the outside of hub bearing improves the cleannes of hub interior, it is ensured that the good lubrication of bearing, and bearing inner race it
Between be closely joined together by connection ring and spacer, contacted with each other by spacer between making two inner rings, in installation process, pass through
The cooperation of two bearings, it is to avoid cooperation situation not in place, improves assembly precision, it is ensured that normally using clearance, and in fact
Show clearance self-regulated, and then improve the life-span of bearing；And then improve the balance and security performance of vehicle.

Specific embodiment
Automobile supporting rear axle assy includes central siphon 1, spindle nose 2, connecting plate 3, brake 4 and rear axle hub 5.Central siphon 1
Two ends are welded by connecting plate 3 spindle nose 2, and brake 4 is housed on spindle nose 2, and one end of spindle nose 2 extends to the outer end of brake 4, prolongs
Extend equipped with rear axle hub 5 on the spindle nose 2 of the outer end of brake 4, rear axle hub 5 is connected with brake 4 by fixing bolt.
Shape is spaced on rear axle hub 5 and is provided with boss 6, bearing A7 wherein is installed on the spindle nose 2 in the outside of side boss 6,
Bearing B8 is installed on the spindle nose 2 in the outside of opposite side boss 6.Bearing A7 and bearing B8 are respectively taper roll bearing, bearing A7
Inner ring outside with bearing B8 is respectively arranged with bearing draw-in groove.Spacer 9, spacer are provided between the inner ring of bearing A7 and bearing B8
9 is diameter-changing body, and the two ends of spacer 9 are respectively arranged with spacer draw-in groove, by connecting between spacer 9 and the inner ring of bearing A7 and bearing B8
Ring 10 by with the mutual clamping of the cooperation of spacer draw-in groove and bearing draw-in groove；By connection ring 10 and spacer 9 by bearing A7 and bearing
The purpose that B8 inner rings link together, one is to solve inner ring to hold caducous problem, and two is to realize that bearing assembles clearance self-regulated
Function, while the installation accuracy of bearing can be improved by the cooperation of boss 6 and spacer 9.
