Abstract
The utility model relates to a wheel hub used in a mini truck, which comprises an inner ring flange, an outer ring flange, inner rings, a cone type roller, a retainer for fixing the roller, and is characterized in that the two inner rings are interference fit with the outer ring flange; the inner ring flange has two upper raceways inside, and two lower raceways are arranged in the two inner rings accordingly; the cone type roller is arranged between the upper raceways and the lower raceways. The inner ring flange is overall connected with a steering knuckle, and the outer ring flange is connected with the wheel hub. The technical proposal shows that replacing steel ball loading with cone type roller loading can meet the requirement for high load and low rotation speed; the two inner rings are interference fit on an outer flange shaft, thus ensuring firm fixing; two raceways are arranged directly on the inner ring flange, increasing the thickness of the flange, enhancing overall strength of the device, making the structure more compact and capable of burdening considerably large axial and radial load (in particular to radial load).
Description
Technical field
The utility model relates to the parts on a kind of automobile, particularly a kind of pickup truck hub bearing assembly.
Background technique
Traditional pickup truck hub bearing generally is to adopt two single-row tapered roller bearings, is pressed in respectively on the wheel columella, is easy to generate various assembly errors in the entrucking process, and selecting for use of two bearings be difficult to unifiedly, has influenced life-span at this position.
Summary of the invention
Technical problem to be solved in the utility model is: on the basis of the problem that overcomes the prior art existence, provide a kind of compact structure, can bear the bigger thrust load and the hub bearing assembly of radial load simultaneously.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of pickup truck hub bearing assembly, bag inner flange, outward flange dish, inner ring, circular cone type roller, the fixing retainer of roller, it is characterized in that: two inner rings and outward flange dish axle interference fit, the inner flange inboard grinds two and goes up raceway, correspondingly be provided with corresponding raceway down at two inner rings, the circular cone type roller is installed in up and down between raceway.
In order to solve the problems of the technologies described above, the utility model adopts following further technological scheme to want:
The both sides of described circular cone type roller are provided with Sealing, and described Sealing is between inner ring and inner flange, and described Sealing and inner ring, inner flange constitute a space that holds lubricating grease.
Described inner flange always is connected with knuckle, and described outward flange dish is connected with wheel hub.
By above technological scheme as can be known: the characteristics of pickup truck are that load-bearing is big, speed is low, replace the steel ball carrying with the tapered roller carrying, satisfied high loading, slow-revving requirement, by two inner ring interference fit are fixed on the outward flange axle, be difficult for sliding, reduced the installation amount of labour of traditional design, by on inner flange, directly making the twice raceway, increased the thickness of flange, improved the bulk strength of these parts, the inboard mill of inner flange processes two raceways, with the outer raceway of two inner rings, tapered roller is formed a rolling structure, makes its structure more compact, can bear sizable axial and radial load (especially radial load) simultaneously, meet the Automobile Design lightweight, integrated advantage.The problem that a plurality of parts cooperatings were easy to generate before the utility model had solved, a kind of solution of integrated, integration is provided, knuckle assembly, brake disc, wheel hub, ectosphere cage are organically combined, both improved part strength, also increased reliability, saved the space, and reduced pts wt, thereby made bearing assembly slim and graceful, compactness, good rigidly, the life-span is long.
Description of drawings
Fig. 1 does not install the structure sectional view of roller state for the utility model.
Fig. 2 installs the structure sectional view of roller state for the utility model.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model is used for pickup truck (or pick up) hub bearing assembly, comprise one with threaded hole 12 inner flange 1, the outward flange dish 2 that 5 above boss bolts 13 are housed, two inner rings 3 and 4, circular cone type roller 5, two inner rings are pressed on the outward flange dish axle by interference fit, grind raceway 6 on two in the inboard of inner flange 1,7, two inner rings 3,4 are provided with corresponding raceway 8 down, 9, tapered roller 5 is down fixing retainer 10, rolling between the raceway up and down, the both sides of circular cone type roller 5 are provided with Sealing 11, Sealing 11 is positioned at inner ring 3,4 and inner flange 1 between, Sealing 11 and inner ring 3 and 4, inner flange 1 constitutes a space that holds lubricating grease.Inner flange 1 links to each other with knuckle assembly by screw thread, and outward flange dish 2 is by bolt 13 and brake disc, and wheel hub links, and has realized the integrated of these parts.As preferably,, the wheel speed counter can be installed as required at the upside of inner flange 1.The internal diameter of flange plate 2 can be established spline outside, so that cooperate with front-wheel drive.The inboard mill of inner flange 1 processes two raceways, form a rolling structure with outer raceway, the tapered roller 5 of two inner rings 3,4, make its structure more compact, can bear simultaneously sizable axially and radial load (especially radial load), meet Automobile Design lightweight, integrated advantage.The advantage of this model utility is: compact structure, and can bear simultaneously and sizablely axially and radial load (especially radial load) meet Automobile Design lightweight, integrated advantage, can play binding, load-bearing, transfer of torque, the effect that turns to.
In actual the use, outward flange dish 2 is during with wheel, drive roller, retainer rotates together, between inner ring 3,4 and the outward flange dish axle slip can not be arranged, and inner flange 1 is fixed on and turns on the assembly, tapered roller 5 has guaranteed to bear radially plants lotus and certain rotation flexibility greatly, this design has linked a plurality of parts, and good rigidly has very big social value.
