The hub flange has the advantages of long service life, low using cost and the like.
Description
Technical field
The utility model belongs to vehicular spare parts technical field, relates to a kind of wheelboss flange.
Background technology
Wheelboss flange is the part of hub-bearing unit in automobile suspension system, and hub-bearing unit, as the support of automotive wheel, possesses the basic function of transmitting torque.Common hub-bearing unit assembling is comparatively complicated, cannot play sealing function.
For the problem of above-mentioned existence, Chinese patent literature data discloses a kind of hub-bearing unit [application number: 200620140765.6 of nut locking, Granted publication number: CN200984943Y], it comprises outer cover, flange, on the step of flange neck, be connected with wheel hub inner ring, inner ring periphery is connected with wheel hub outer ring, between inner ring and flange neck step place and outer ring, be provided with rolling body, inner side, outer ring is provided with symmetrical double channel, the contact surface in its cross section has the arc surface suitable with rolling body, be located at the non-leading end face of outer ring outward, its inner side is directly relative with the nut that is located at inner ring large end face and lock with flange neck, it and nut, inner ring large end face and flange neck end form chamber, the axle journal place of flange is provided with screw thread, nut is screw thread fit therewith, and nut contacts with inner ring large end face, rolling body is fixedly connected with by retainer, retainer is through the center of gravity of rolling body, wheel hub cycle surface is provided with some threaded bolts hole.
Above-mentioned patent has good sealing property, compact conformation, volume is little, but it is the same with existing hub-bearing unit, all exists and safeguard that inconvenient problem, in use bearing fail in compression need to change, because bearing is to be inserted in tightly flange neck, so bearing inconvenience dismounting, all directly changes flange while changing bearing at present together, has so just increased use cost.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, and a kind of easy to maintenance, wheelboss flange that can reduce use cost is provided.
The purpose of this utility model can realize by following technical proposal: a kind of wheelboss flange, comprise the fixed part that is circular and be card-tight part cylindraceous, described card-tight part is outstanding from fixed part one side direction with the coaxial setting of fixed part and its, it is characterized in that, described fixed part has the step that a corral arranges around card-tight part, the side opening of described step is provided with dismounting groove, and described dismounting groove is through to the step surface of step and makes the edge of step surface form one section of breach.
During installation, fixed part is installed fixing for wheel, be installed on card-tight part to bearing interference fit, and bearing inner ring contacts at the step surface of step; While safeguarding, by fixture or skid plate, snap in dismounting groove, fixture or skid plate apply removal force by the breach of step surface edge to bearing inner ring, bearing is departed from from card-tight part, easy to maintenance like this, only need to change to damage bearing, avoid this wheelboss flange to change with bearing, extend the service life of this wheelboss flange, reduced use cost.
In above-mentioned a kind of wheelboss flange, described fixed part has a corral around card-tight part setting and is positioned at the support level under step, and the side of described support level is conical suface.Support level has increased structural strength, has improved the service life of this wheelboss flange.
In above-mentioned a kind of wheelboss flange, described dismounting groove extends to support level place and dismounting groove is the groove of enlarging shape, and the width of rebate of described dismounting groove is greater than the bottom land width of dismounting groove.Facilitate like this fixture to snap in, it is convenient to dismantle.
In above-mentioned a kind of wheelboss flange, the quantity of described dismounting groove is for two or three and dismantle the side that groove is uniformly distributed in step.Facilitate like this jig Design, well-distributed dismounting groove is evenly distributed the removal force that bearing inner ring obtains, and bearing departs from smooth and easy from card-tight part, can local pressure not uneven and stuck phenomenon occurs.
Compared with prior art, this wheelboss flange simple in structure, intensity is high, and long service life, and facilitate the replacing of bearing makes easy to maintenancely, has reduced use cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of this wheelboss flange.
In figure, 1, fixed part; 2, card-tight part; 3, step; 3a, side; 3b, step surface; 4, dismounting groove; 5, support level.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this wheelboss flange comprises the fixed part 1 that is circular and is card-tight part 2 cylindraceous, card-tight part 2 is outstanding from fixed part 1 one side direction with the coaxial setting of fixed part 1 and its, fixed part 1 has the step 3 that a corral arranges around card-tight part 2, the side 3a of step 3 offers dismounting groove 4, and dismounting groove 4 is through to the step surface 3b of step 3 and makes the edge of step surface 3b form one section of breach.Fixed part 1 also has a corral around card-tight part 2 settings and is positioned at the support level 5 under step 3, the side of support level 5 is conical suface, dismounting groove 4 extends to support level 5 places and dismounting groove 4 is the groove of enlarging shape, and the width of rebate of dismounting groove 4 is greater than the bottom land width of dismounting groove 4.The quantity of dismantling groove 4 in the present embodiment is the side 3a that two and dismounting groove 4 are uniformly distributed in step 3.
During installation, fixed part 1 is installed fixing for wheel, be installed on card-tight part 2 to bearing interference fit, and bearing inner ring contacts at the step surface 3b of step 3; While safeguarding, by fixture, snap in dismounting groove 4, fixture applies removal force by the breach of step surface 3b edge to bearing inner ring, and well-distributed dismounting groove 4 is evenly distributed the removal force that bearing inner ring obtains, and bearing departs from smooth and easy from card-tight part 2, can local pressure not uneven and stuck phenomenon occurs, easy to maintenance like this, only need to change to damage bearing, avoid this wheelboss flange to change with bearing, extend the service life of this wheelboss flange, reduced use cost.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although more used the terms such as fixed part 1, card-tight part 2, step 3, side 3a, step surface 3b, dismounting groove 4, support level 5 herein, do not got rid of the possibility of using other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
