Specific implementation mode
The core of the utility model is to provide a kind of bearing plate, to guarantee dust-proof and compress outside axle bearing
Under the premise of circle, rigging error is reduced, improves intensity；
Another core of the utility model is to provide a kind of drive axle with above-mentioned bearing plate.
Hereinafter, being illustrated to embodiment with reference to attached drawing.In addition, embodiments illustrated below is not to recorded in claim
Utility model content rise any restriction effect.In addition, the full content of the composition represented by following example is not limited to conduct
Necessary to the solution of utility model recorded in claim.
Referring to Fig. 2, Fig. 2 is the partial sectional view for the drive axle that the utility model embodiment provides.
It includes bearing outer ring positioning region and dustproof part that the utility model embodiment, which discloses a kind of bearing plate 101,.Wherein,
Bearing outer ring positioning region is the main part of bearing plate 101, the outer ring for compressing axle bearing 103.Dustproof part and bearing
Outer ring positioning region is an integral structure, and the endoporus of dustproof part is used to coordinate with semiaxis.The bearing plate 101 is preferably integral type forging
Pressing plate is made, there can be better intensity by forging, effectively compress axle bearing, has by machining mounting surface and preferably matches
It closes that accuracy guarantee is dust-proof, waterproof, and only needs a part.
Bearing outer ring positioning region and dustproof part setting are an integral structure, make by bearing plate provided by the utility model
The bearing plate 101 is obtained other than having the function of bearing outer ring and positioning, is also had the function of dust-proof.Using the bearing plate
101, dust excluding plate in the prior art can be saved, i.e. pressing plate in the prior art and dust excluding plate are integrated into one by the utility model
A component reduces a part, and structure is simpler, is not only easy to assemble, and since part is few so that assembly precision is more
Height, intensity higher.
In a specific embodiment of the present invention, bearing outer ring positioning region and dustproof part not in the same plane, and axis
Bearing outer-ring positioning region is connect with dustproof part by transition part.Bearing outer ring positioning region, which needs to be bonded, is fixed on casing flange 102
On end face, after installation, dustproof part relative to bearing outer ring positioning region far from axle bearing 103, to be reserved more for other component
Installation space, certainly under the premise of not considering installation space, dustproof part also can be relative to bearing outer ring positioning region close to semiaxis
Bearing 103 is arranged.And it is designed using this bending structure, intensity also higher.It should be noted that bearing outer ring positioning region
It also can be in the same plane with dustproof part.
In a specific embodiment of the present invention, the plate thickness of bearing outer ring positioning region is more than the plank thickness of dustproof part
Degree.Since bearing outer ring positioning region needs to be fixed on casing flange 102, there are active forces between axle bearing 103, and
There are minim gaps between dustproof part and semiaxis 104, therefore the thickness design of the bearing outer ring positioning region is thicker, helps to carry
The service life of high bearing plate.Due to consideration that the problem of bearing plate weight, therefore select bearing outer ring positioning region and prevent
Dirt portion uses the processing mode of different-thickness, is not only able to ensure the intensity of bearing plate, can also reduce overall weight.
In a specific embodiment of the present invention, it is offered on bearing outer ring positioning region for wearing fixing bolt 106
Bolt hole.Bearing outer ring positioning region can be mounted on casing flange 102 by fixing bolt 106.
The utility model embodiment also discloses a kind of drive axle, including casing flange 102 and is set by axle bearing 103
The semiaxis 104 being placed on casing flange 102, the utility model focus on, and further include bearing pressure disclosed in above-described embodiment
Plate 101.Bearing plate 101 is sheathed on semiaxis 104, and is fixedly connected with the end face of casing flange 102, specifically can be by solid
Determine bolt and passes through bearing outer ring positioning region and casing flange 102.Since the drive axle is using bearing pressure disclosed in above-described embodiment
Plate 101, therefore all technique effects of above-mentioned bearing plate 101 are had both, it repeats no more herein.
In a specific embodiment of the present invention, the utility model may also include the oil sealing being sheathed on semiaxis 104
105, and oil sealing 105 can further prevent muddy water to invade axle bearing between bearing plate 101 and axle bearing 103
103.Further, dustproof part relative to bearing outer ring positioning region far from axle bearing 103, and the width of the endoporus of oil sealing 105
More than the width of peripheral surface.It should be noted that oil sealing 105 and the contact area of casing flange 102 and semiaxis 104 are bigger, it is close
It is better to seal effect.But it is influenced by space between bearing plate 101 and axle bearing 103, oil sealing 105 and casing flange
102 contact area can not accomplish bigger, and by extending dustproof part to the direction far from axle bearing 103, can be oil
Envelope 105 and the contact area increase of semiaxis 104 provide help.
In a specific embodiment of the present invention, the mounting base for installing caliper is provided on casing flange 102.
Preferably, mounting base is an integral structure with casing flange 102.Since mounting base and casing flange 102 are an integral structure, make
It obtains caliper to can be directly mounted on casing flange 102, to eliminate the use of intermediate connector, and in casing flange
In 102 production process, because keeping the difficulty of processing of the depth of parallelism between single part different surfaces relatively low, can fully it protect
Precision is demonstrate,proved, to avoid influence of the rigging error to brake disc and caliper cooperating to the greatest extent, to reduce disc type system
The vibrating noise that dynamic device generates in use improves disk brake in small and medium-sized car, especially SUV (Sport
Utility Vehicle, sport utility vehicle) vehicle driving rear axle on using effect.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use this practicality new
Type.Various modifications to these embodiments will be apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest range consistent with features of novelty.
