Abstract
The utility model discloses a semi -floating rear drive axle anticreep wheel limit structure, it includes semi -axis, bearing frame, half bearing, bearing nut packing ring, bearing nut and bearing frame oil blanket, half bearing pressure equipment bearing frame is inside and install the shaft shoulder, bearing nut packing ring and bearing nut locking through the semi -axis, is equipped with the anticreep retaining ring between half bearing and bearing nut packing ring. The utility model discloses a setting up the anticreep retaining ring between half bearing and bearing nut packing ring, after half bearing damages, can preventing effectively that semi -axis area bearing inner race breaks away from from the pontic, more the braking bottom plate bolt interlinkage fixed bearing base and the axle housing assembly of high strength in addition, are used to the elimination potential safety hazard, can further improve rear drive axle's stable ability.
Description
Technical field
This utility model is related to a kind of semi-floating drive axle, and in particular to a kind of semi-floating rear driving axle anticreep wheel side knot
Structure.
Background technology
Used as automotive transmission end, its effect is to pass to the axle shaft gear that torque has differential mechanism on the wheel side of drive axle
Driving moment, axle bearing plays the function of bearing load, and the pull strength of automobile, brake force, side force and vertical force are final
It is delivered on bearing.Back-plate bolt plays link and fixed bearing block and brake assembly and axle case assy.Nowadays,
The performance requirements such as the carrying with rear driving axle also more and more higher；Because of bearing type selecting, back-plate bolt type selecting, the structure of semiaxis
And size design, the bearing damage of the improper initiation of assembling on wheel side or back-plate bolt fracture and then half when causing running car
The accident of shaft pulley tire abjection happens occasionally, the life security of serious threat occupant；Therefore consideration is needed to prevent tire in designing
The measure that abjection accident occurs.
Existing full floating rear driving axle adopts large-sized bearing nut, the bearing nut playing regulation hub bearing
Pretension degree while, also have the generation that semiaxis when preventing axle bearing from damaging deviates from accident concurrently.And existing semi-floating
Back axle, because structure is limited or the cognitive not enough structure for being not provided with effectively preventing semiaxis from deviating from accident, when axle bearing is damaged,
Easily there is the security incident of the related tire abjection of whole semiaxis from after pontic disengaging in built-in rolling element.
The content of the invention
This utility model purpose is to provide a kind of semi-floating rear driving axle anticreep wheel side structure.
What this utility model was realized in：
A kind of semi-floating rear driving axle anticreep wheel side structure, it includes semiaxis, bearing block, axle bearing, bearing nut pad
Simultaneously the shaft shoulder, bearing nut are installed by semiaxis in circle, bearing nut and bearing block oil sealing, the axle bearing Fitted Axles bearing inside
Packing ring and bearing nut are locked, and anticreep back-up ring is provided between axle bearing and bearing nut packing ring.
Further, bearing block oil sealing is stuck in the radial clearance of bearing block and semiaxis.
Further, maximum inner diameter of the external diameter of the anticreep back-up ring more than axle bearing outer ring.
Further, the bearing block is anchored on axle case assy by back-plate bolt.
This utility model by between axle bearing and bearing nut packing ring arrange anticreep back-up ring, when axle bearing damage
Afterwards, can effectively prevent semiaxis band bearing inner race from departing from from pontic, eliminate safe hidden trouble, additionally, using the braking bottom of higher intensity
Crab bolt links fixed bearing block and axle case assy, can further improve the stability of rear driving axle.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, semiaxis 1, bearing block 2, axle bearing 3, bearing nut packing ring 4, bearing nut 5, back-plate bolt 6, bridge
Housing assy 7, anticreep back-up ring 8, bearing block oil sealing 9.
Specific embodiment
It is suitable for new technology contents, structural features, target and effect realized, below in conjunction with enforcement to describe this in detail
Mode simultaneously coordinates accompanying drawing to be explained.
As shown in Figure 1：A kind of semi-floating rear driving axle anticreep wheel side structure, it includes semiaxis 1, bearing block 2, axle bearing
3rd, bearing nut packing ring 4, bearing nut 5 and bearing block oil sealing 9, the inside of 3 Fitted Axles bearing of the axle bearing 2 simultaneously passes through semiaxis
The 1 installation shaft shoulder, bearing nut packing ring 4 and bearing nut 5 are locked, and between axle bearing 3 and bearing nut packing ring 4 anticreep is provided with
Back-up ring 8.
Bearing block oil sealing 9 is stuck in the radial clearance of bearing block 2 and semiaxis 1.
Maximum inner diameter of the external diameter of the anticreep back-up ring 8 more than the outer ring of axle bearing 3.
The bearing block 2 is anchored on axle case assy 7 by back-plate bolt 6.
This utility model first passes through frock general, axle bearing 3 and press-fits on bearing block 2, then be pressed into semiaxis 1, is inciting somebody to action
Anticreep back-up ring 8, bearing nut packing ring 4 are inserted in successively on semiaxis 1, are locked using bearing nut 5, and wheel side assembly is being used into braking bottom
On axle case assy 7, anticreep back-up ring 8 is being used more the fixed-link of crab bolt 9 with diameter greater than the seal mounting hole diameter of bearing block 2
The link of back-plate bolt 9 of high intensity is fixed on after axle case assy 7, and after axle bearing is damaged, anticreep back-up ring 8 can effectively be prevented
Only semiaxis band bearing inner race departs from from axle case assy 7, and existing semi-floating wheel structure in structure and this utility model wheel is pressed
De- power contrast, existing semi-floating wheel side structure pressure-off power is only 26KN, and the pressure-off power of this utility model wheel side structure is
180KN。
