Description
Technical field
The present invention relates to a kind of automobile hub bearing, specifically a kind of high rigidity long lifetime hub-bearing unit.
Background technique
Hub bearing is the important walking parts of automobile.Hub bearing is being undertaken the surface friction drag when reducing the chassis running, keeps the important task of automobile normal running.In existing automotive hub revolution is supported; What adopt is the bearing unit structure; What in small-sized passenger car, adopt is the spherical hub-bearing unit assembly of biserial angle contacting; And,, adopt cone type hub-bearing unit assembly mostly owing to require bearing capacity big on the commercial car such as commercial vehicle, go-anywhere vehicle.Hub bearing except bearing thrust load, also will bear warp-wise load in the rotation process of load-bearing and wheel hub, but in practice: incapability is a ball bearing; Or tapered roller bearing; Force-bearing situation is very complicated, though it is a lot of to influence the factor in hub bearing life-span, concludes and gets up can be divided into two aspects; The one, the influence of system's other factor is like road conditions, driving operation etc.; The 2nd, the influence of system intrinsic factor is like the concrete structure of load distribution and hub spindle bearing etc.Cause the reason of hub-bearing unit generation early failue, in general, the metal fatigue of the low and rolling surface of contact of rolling bearing rigidity is the principal element of rolling bearing generation early failue and damage.Therefore, have the hub-bearing unit structure now, can not satisfy the needs of automobile industry development.
Summary of the invention
The present invention is directed to the deficiency of existing hub-bearing unit structural design, a kind of high rigidity long lifetime hub-bearing unit is provided.Through in inner flange cylindrical and outward flange dish, establishing three annular sphere raceways on the corresponding disc of circle; Retainer and steel ball are installed in the annular sphere raceway respectively; Changed the structure of hub; Strengthen the rigidity and the anti-metal fatigue intensity of rolling surface of contact of rolling bearing, can effectively bear bigger thrust load and warp-wise load, improved the reliability and the working life of hub-bearing unit greatly.
Technological scheme of the present invention is: high rigidity long lifetime hub-bearing unit comprises outward flange dish, inner flange, inner ring, steel ball, retainer, O RunddichtringO, rubber seal, magnetic dust cover and bolt; Be provided with protruding crimping in the inner flange left part; Form groove between the step of establishing on crimping that the inner flange left end is protruding and the inner flange cylindrical; Inside race is sleeved in the groove on the inner flange left end cylindrical, and the crimping protruding by left end is locked at inside race in the groove; The corresponding disc of circle is provided with the first annular sphere raceway in inside race cylindrical and the outward flange dish; Inside race right-hand member head and the inner flange cylindrical end face of topping bar combines; The corresponding disc of circle is provided with the second annular sphere raceway in the periphery of inside race and inner flange cylindrical step junction and the outward flange dish; Inner flange cylindrical step is provided with gear ring, is coupled with wheel speed sensors (not drawing) on this gear ring; The corresponding disc of circle is provided with the 3rd annular sphere raceway in inner flange right-hand member cylindrical and the outward flange dish right-hand member.
Establish between the first annular sphere raceway, the second annular sphere raceway and the 3rd annular sphere raceway on the circle in described inside race cylindrical and the outward flange dish first retainer, second retainer and the 3rd retainer are installed, in three row retainers, steel ball is installed respectively; Establish the O RunddichtringO on the flange plate left end cylindrical outside; The left end cylindrical of inside race and outward flange are faced left and are provided with first rubber seal and magnetic dust cover between the interior circle of end; Be provided with second rubber seal between the circle in the right-hand member cylindrical of inner flange and the right-hand member of outward flange dish, to guarantee inner disc and outward flange dish sealed at both ends.
A kind of high rigidity long lifetime hub-bearing unit of the present invention is equipped with knurled nut 9 on the flange that is connected as a single entity with inner flange.
The invention has the beneficial effects as follows: through in inner flange cylindrical, inside race cylindrical and outward flange dish, setting up steel ball rolling channel between the circle; Retainer and steel ball are installed in setting up raceway; Change the hub internal structure, strengthened the stiffness and the anti-metal fatigue intensity of rolling surface of contact of rolling bearing; Hub-bearing unit bearing capacity and hub-bearing unit working life have been improved.
