Description
The utility model relates to a kind of drive mechanism of automotive hub, especially to the structural improvement of a kind of transmission (bearing) of drive wheel wheel hub part.
Existing drive wheel bearing-hub assembly tie up to wheel hub outer ring 2 ' the inboard be provided with two bearings 4 and place wheel shaft in it, rely on pad and clamp nut to be fixed into one.The outside of two bearings, wheel hub outer ring 3 ' be arranged at.During use, on the whole brake disc that is fixed on automobile with bolt 20 (referring to accompanying drawing 1).Though this structure adopts general-duty bearing standard spare, need not independent production, exist structure and owe compact, volume is bigger, and bearing capacity is less, safeguards deficiencies such as inconvenience.
For this reason, the utility model of people in " a kind of trailer wheel hub " (patent No. 92202626.2) by name arranged, it is partly to be made up of bearing seat, left bearing bearing, right bearing bearing, reaction plate and spoke etc.Wherein, bearing seat all adopts arcwall face to be connected with the joint of spoke, reaction plate, and the cavity in the bearing seat also is connected for arcwall face with its inwall.Though it is not high that it has improved some existing structure of right angle tyoe wheel hub load-carrying capacitys, the deficiency of easy fracture is suitable for using than the complex road surface vehicle.But still it is bigger to exist volume, and it is high that load-carrying capacity is owed, and it is compact that structure is owed, and safeguards deficiencies such as very not convenient.
Goal of the invention of the present utility model provides a kind of compact conformation, and is in light weight, bearing capacity height, the drive wheel bearing-hub assembly of simplification car wheel structure.
Another goal of the invention of the present utility model provides a kind of installation, easy to maintenance, lifelong self-lubricating, the drive wheel bearing-hub assembly that exclusion seal is good.
Foregoing invention purpose of the present utility model can be achieved by following technical proposals: the periphery at described flange is fixed with a ball circling lane, be equipped with an interior ring that is provided with a ball circling lane thereon, and on alley, being equipped with rolling body, it is outer for being provided with the wheel hub outer ring with two alleys.Can cooperate at the flange top offset owing to be provided with the interior ring of alley, make it manufacturing, easy for installation.
Middle inside is provided with bulge loop in the wheel hub outer ring, and its both sides respectively are an open alley; And the annulus and the alley on the both sides of inboard, wheel hub outer ring are tangent.This structure is when guaranteeing safety, operation well, for the assembling of liquid brings great convenience.
For the further ability that improves sealing property of the present utility model and be applicable to harsh environment, an end and flange in inboard, wheel hub outer ring, nearly base portion place is provided with a labyrinth seal circle; Described seal ring system adopts rubber to make, and which is provided with the Connection Block that matches with dermoskeleton frame end portion, and is integral by skeleton is bonding outside Connection Block and the metal; The cross section of described outer skeleton is made of L-shaped outside and quiet side; And its edge break is to reverse side; The moving side of inner frame is a folding face, and its end is free.
The outside of ring is provided with the play ring successively in described, baffle ring, and fastening has cover of dust outside it.In addition, be provided with alley in the inboard of described wheel hub outer ring, the contact surface in its cross section is the arc surface that matches with rolling body, is provided with inner ring below rolling body, and its inside face and wheel shaft phase configuration, its periphery are provided with the holder bearing surface that matches with rolling body.
The inboard of described wheel hub outer ring is provided with two described inner rings of alley and is divided into two, and the holder bearing surface of its periphery is located at the outside of inner ring, and places therebetween rolling body by its alley clamping with the wheel hub outer ring.
In addition, between the outerplanar of wheel hub outer ring, plane alley on the outside of described inner ring holder bearing surface, be provided with the labyrinth seal circle; Described seal ring system is provided with the static seal circle body by an end of skeleton outside, and the main lip interference fit of static seal circle body is in the inboard of inner frame; And being provided with the dynamic seal circle body at an end of inner frame, lateral lip that its outer periphery is provided with and outer lip difference interference fit are in the inboard of outer skeleton.
Therefore, the utlity model has following advantage:
1. simple in structure, each arrangements of elements compactness can be cancelled the bigger conical bearing of volume, only keeps rolling body (bearing ball) and two outside racees all touch with the wheel hub outer ring and close in one, and bearing inner ring then replaces it by inner ring.
2. owing to get the part-structure of having simplified bearing, reduce volume, alleviated overall weight, reduced productive costs, and can suitably increase the sphere diameter of rolling body, improved load-carrying capacity.
3. assembling is simple, easy to maintenance.During assembling, only need be provided with in two alleys on the wheel hub outer ring rolling body of band retainer, axially insert two inner rings in it, retainer be that tuck pointing is in the inner ring draw-in groove, even assembled fuses; And place the labyrinth seal circle good dustproof effect of its outer ring, and make its lifelong self-lubricating.
Fig. 1 is the structural representation of a kind of bearing-hub assembly of the prior art.
Fig. 2 is a kind of agent structure cutaway view in the utility model.
Fig. 3 is the local structure enlarged drawing of the A portion among Fig. 2.
Below by embodiment, and in conjunction with the accompanying drawings, structure of the present utility model is done concrete description.
Embodiment: be provided with twice open alley 10 parallel to each other in the inboard of wheel hub outer ring 3, be separated by by bulge loop 30 therebetween, it is built-in with staggered two row rolling bodys 7, and by retainer 71 it is kept the distance each other.Be provided with a ball circling lane on flange 2, an inboard row rolling body is placed on it; On interior ring 8, be provided with a ball circling lane, the displacement location of ring in a row rolling body in the outside relies on, suitable position also can be adjusted according to the thickness of selected play ring 11, and the latter relies on baffle ring 12 location, its outer fastening again has cover of dust 13.Between the inboard of wheel hub outer ring 3 and flange, be provided with the labyrinth seal circle, outer skeleton in the described labyrinth seal circle is to become L shaped annulus with punching of the steel plate, the end of quiet side is bonded with the Connection Block 31 of the sealing circle body of being made by rubber, its main lip 32 is hook-type, secondary lip 33 is chevron pointing with main lip 32 and arranges, lateral lip 35 is folded to moving side 42 proximal ends of inner frame, and the moving side 42 of inner frame is folding face (on-plane surface) shape, and the end is free.During assembling, with main lip 32 and the secondary lip 33 and inner edge 41 interference fit of sealing circle body 3; Lateral lip 35 and moving side 42 interference fit (referring to accompanying drawing 3).
When practical set, the inboard that the wheel shaft of automobile non-driving wheel 4 inserts two ring-type inner rings 8, the step of wheel shaft 4 is pressed and is blocked an inner ring, another inner ring then by nut 6 through pad 5, whole assembly is closely pressed together.Then whole assembly is installed in bolt 60 on the wheel hub of wheel and gets final product.
