Abstract
The utility model discloses a semi -floating rear drive axle semi -axis mounting structure, including the semi -axis oil blanket of semi -axis, bearing frame, axle housing assembly, bearing frame front end and set gradually wheel hub bearing, bush and the jump ring in the bearing frame, the bearing frame seat is downthehole, is located to be equipped with the round tang between semi -axis oil blanket mount pad hole and the wheel hub bearing mount pad hole, and the internal diameter of tang is less than wheel hub bearing inner race's maximum outer diameter, is greater than the maximum diameter of semi -axis axle body. The utility model discloses a set up the round tang between semi -axis oil blanket and wheel hub bearing, after wheel hub bearing failure, this improved generation bearing frame can prevent effectively that semi -axis area bearing inner race breaks away from from the pontic, the elimination potential safety hazard, moreover because the tang has reduced the clearance between semi -axis axle body and the bearing frame, can prevent that trouble wheel hub bearing from scattering and lose, be favorable to follow -uply to carry out detection and analysis to trouble spare part.
Description
Technical field
This utility model relates to a kind of semi-floating rear drive axle differential axle mounting structure.
Background technology
Along with the day by day fierce market competition, the update speed of car load factory new model is forced constantly to be accelerated, to rear-guard
The requirement of the performances such as the carrying of dynamic bridge is more and more higher.
Existing rear driving axle is roughly divided into two classes: full floating rear driving axle and semi-floating rear driving axle.Full floating rear-guard
Dynamic bridge uses large-sized bearing nut, and this bearing nut is while playing the pretension degree of regulation hub bearing, also have concurrently
The generation of semiaxis abjection accident when preventing hub bearing from damaging.
And existing semi-floating back axle, it is not provided with effectively preventing the mechanism of semiaxis abjection accident, especially because structure limits
Being when hub bearing damages, after pontic departs from, easily there is the safety of whole semiaxis related tire abjection in built-in rolling element
Accident.Therefore design considering, the measure preventing tire abjection accident from occurring is the most necessary.
Utility model content
The purpose of this utility model is to optimize the deficiency of existing production technology, adapts to reality need, it is provided that a kind of half floats
Formula rear drive axle differential axle mounting structure.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of semi-floating rear drive axle differential axle mounting structure, including semiaxis, bearing block, axle case assy, bearing block front end
Axle-shaft oil seal and the hub bearing being successively set in bearing block, lining and jump ring, in described bearing block bore, be positioned at half shafting oil
Envelope installs bore and hub bearing is installed and is provided with a circle seam between bore, and the internal diameter of seam is less than the maximum of hub bearing inner ring
External diameter, more than the maximum gauge of semiaxis axle body.
The inner of described seam is provided with seam step, and the internal diameter of seam step is more than the center-diameter of hub bearing.
Distance between outer end and the bearing block front end of described seam is not less than the thickness of axle-shaft oil seal.
The beneficial effects of the utility model are: by arranging a circle seam between axle-shaft oil seal and hub bearing, work as wheel
After hub bearing damage, this improved axis bearing can effectively prevent semiaxis band bearing inner race from departing from from pontic, eliminates safe hidden trouble；Again
Person decreases the gap between semiaxis axle body and bearing block due to seam, can prevent fault hub bearing be scattered loss, be conducive to
Follow-up carry out fault parts detects analysis.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: semiaxis 1, axle-shaft oil seal 2, bearing block 3, hub bearing 4, lining 5, jump ring 6, axle case assy 7, bolt 8, spiral shell
Female 9.
Detailed description of the invention
This utility model by the following examples can the utility model will be further described, but, this practicality
Novel scope is not limited to following embodiment.
Embodiment: as shown in Figure 1；
A kind of semi-floating rear drive axle differential axle mounting structure, before semiaxis 1, bearing block 3, axle case assy 7, bearing block 3
The axle-shaft oil seal 2 of end and the hub bearing 4 being successively set in bearing block 3, lining 5 and jump ring 6, the axle body of described semiaxis 1 depends on
Secondary it is socketed with bearing block 3 through axle-shaft oil seal 2, hub bearing 4, lining 5, in described bearing block 3 bore, is positioned at axle-shaft oil seal 2
Installing bore and hub bearing 4 is installed and is provided with a circle seam between bore, the internal diameter of seam is less than the maximum of hub bearing 4 inner ring
External diameter, more than the maximum gauge of semiaxis 1 axle body.
The inner of described seam is provided with seam step, and the internal diameter of seam step is more than the center-diameter of hub bearing 4, i.e. circular cone
The distribution diameter of roller, it is simple to the lubrication of taper roller and heat radiation.
Distance between outer end and bearing block 3 front end of described seam is not less than the thickness of axle-shaft oil seal 2.
Specifically assemble process；First pass through frock and hub bearing 4 is press-fited in bearing block 3, axle-shaft oil seal 2 is only placed on
On mouth outer end, semiaxis 1 is sequentially passed through axle-shaft oil seal 2, hub bearing 4 and lining 5 and press-fits, use jump ring 6 spacing, enter one
Step is anchored on axle case assy 7 by bolt 8, nut 9.When hub bearing 4 damages for some reason, the semiaxis of rotation will laterally
Motion, because being provided with a circle seam and seam internal diameter less than hub bearing 4 in the inner ring side near hub bearing 4 on bearing block 3
The external diameter of the maximum of inner ring, therefore bearing block 3 plays a part to prevent semiaxis 1 from deviating from；Simultaneously because of seam and the semiaxis of bearing block 3
The gap hub bearing 4 little, fault preset between 1 is difficult to loss of being scattered, and is conducive to detection and analyzes the former of hub bearing damage
Cause, can avoid the appearance of bearing damage further.
