Abstract
The invention relates to a dust prevention component of an automobile hub bearing. The dust prevention component is arranged between an ABS gear ring and a steering knuckle, and comprises a mounting part matched with a driving shaft; the mounting part is cylindrical and flanges extending outwards are formed on the two sides of the mounting part in a surrounding manner; the flange on one end of the mounting part is a dust prevention part matched with the steering knuckle, while the flange on the other end is a positioning part fitted with the step surface of the driving shaft; the fit gap of the dust prevention part and the steering knuckle is not larger than 0.5mm. The dust prevention component of the automobile hub bearing is simple in structure and convenient to manufacture, and can be directly molded by pressing by use of a die; the dust prevention component is ingenious in design; the gap between the ABS gear ring and the steering knuckle is utilized thoroughly, and consequently, impurities such as dust can be prevented from going into the hub bearing and the risk of misreading of wheel speed data due to the accumulation of the dust on the ABS gear ring can be avoided; besides, a zinc coating is formed to prevent rusting and prolong the service life of the dust prevention component.
Description
Technical field
The present invention relates to automobile hub bearing sealing structure is and in particular to a kind of automobile hub bearing dust-proof member.
Background technology
Automobile hub bearing is arranged on automotive hub, mainly plays load-bearing and provides accurately guiding for rotating of wheel hub
Effect, it had not only born axial load but also had born radial load, was one very important parts of Hyundai Motor.Drive shaft assembly
After the assembling of brake knuckle, there is larger gap between the two, in running car, dust that wheel is splash, mud
Hub bearing can be entered Deng impurity, cause hub bearing heel and toe wear, substantially reduce its service life, especially road conditions less preferably
Section, more makes hub bearing easily be contaminated, and needs to arrange dustproof construction therefore between hub bearing and drive shaft.
Vehicle ABS anti-lock braking system is to detect wheel by the signal of locking by the sensor being arranged on wheel,
It is made up of permanent magnet, magnetic pole, coil and ABS gear ring.When gear ring rotates in magnetic field, between gear ring tooth top and electrode between
Gap just with certain velocity variations, then makes the magnetic resistance in magnetic circuit change.Its result is so that magnetic flux is increased and decreased periodically, online
The two ends of circle produce the induced voltage being proportional to magnetic flux speed of increasing and decrease, and this ac voltage signal is conveyed to Electronic Control
Device, controller receives wheel and will be reduced the oil pressure of this wheel brake cylinder by the signal instruction actuator of locking, reduces system to reach
The purpose of kinetic moment.The dustproof construction using between hub bearing and drive shaft at present is specially to set on ABS gear ring mostly
One dust-proof face of meter（As shown in Figure 5）, though the impurity such as this structure energy blocks dust enters bearing, also easily makes the impurity such as dust
Each inter-lobe clearance at the dust-proof face of ABS gear ring is piled up.Because wheel speed sensors are for the tooth height of ABS gear ring, transverse tooth thickness, the facewidth
There is higher requirement etc. parameter, after dust accretions on ABS gear ring, there is vehicle wheel speed sensor and read the wind that data is misread
Danger.
Content of the invention
It is an object of the invention to provide a kind of automobile hub bearing dust-proof member, this dust-proof member is arranged on Automobile drive
On axle, not only can prevent the impurity such as dust from entering hub bearing, and be avoided that because dust piles up on ABS gear ring and cause
The risk that wheel speed data is misread.
A kind of automobile hub bearing dust-proof member of the present invention, is arranged between ABS gear ring and knuckle, including with
The installation portion of drive shaft cooperation, installation portion is cylindrical in shape and is all surrounded with outward extending flange at its two ends；Described installation portion
The flange of one end is the dustproof part with the cooperation of described knuckle, and the flange of the other end is to fit with the step surface of described drive shaft
Location division；Described dustproof part is not more than 0.5mm with the fit clearance of described knuckle.
Using technique scheme, described dust-proof member is arranged on the axle journal of drive shaft by installation portion cooperation, fixed
Position portion is fitted with the step surface of drive shaft to ensure the axially mounted dimensional accuracy of dust-proof member.And now ABS gear ring is due to cancelling
Dust-proof face, the dust entering ABS gear ring can flow in each inter-lobe clearance, it is to avoid the impurity such as dust is in ABS gear ring
Accumulation causes wheel speed data to misread.And then stopped by dustproof part by impurity such as the dusts within inter-lobe clearance entrance, prevent
Radial clearance between the outer rim in dirt portion and knuckle is not more than 0.5mm, forms the annular slot of a gap very little, Neng Gou great
The big amount of dust reducing entrance hub bearing, thus reach dust-proof effect.
Improve as a kind of, the maximum gauge of described location division is less than the internal diameter of described ABS gear ring, it is to avoid location division with
ABS gear ring interferes and cannot axially be accurately positioned.
Improve as a kind of, at the opening at described installation portion two ends, be equipped with fillet, fillet has guide effect, convenient peace
Dress.
Further, described installation portion leans on the radius of the fillet of described location division one end to be more than the step surface of described drive shaft
Processing fillet radius, can fit tightly with the step surface of drive shaft in order to location division.
Improve as a kind of, its surface is provided with spelter coating, is prevented from corrosion.
Improve as a kind of, described dustproof part, location division, the wall thickness of installation portion are respectively less than 1mm, because the present invention is served only for
Dust-proof, it is not subject to load or stress, less wall thickness is set and just disclosure satisfy that use demand, simultaneously facilitate compressing, energy
Enough cost-effective.
The present invention also provides a kind of automobile hub bearing dustproof construction, including above-mentioned automobile hub bearing dust-proof member.
In sum, present configuration is simple, easy to make, can pass through mould direct pressing molding；Design is ingenious, fully
Using the space between ABS gear ring and knuckle, not only can prevent the impurity such as dust enter hub bearing, and be avoided that because
Dust is piled up on ABS gear ring and is caused the risk that wheel speed data misreads；It is provided with spelter coating, is prevented from corrosion, extend and use
Life-span.
