Abstract
The utility model discloses a truck front shaft hub structure. According to the technical scheme, the truck front shaft hub structure comprises a hub, wherein a hub inner hole is a bearing inner hole which is coaxial with the hub and is integrally cylindrical, and an integrated bearing unit is arranged in the bearing inner hole. The truck front shaft hub structure has the beneficial effects of simple structure and low processing and manufacturing cost, and realizes that the bearing unit and a brake disk are installed through an innovative design on the premise of no influence on the installing function of the wheel.
Description
Technical field
The utility model is a kind of truck front axle wheel hub structure, belongs to the auto parts and components field.
Background technology
The present used wheel hub of truck front axle, through the installation of wheel bolt realization wheel, two single-row tapered roller bearings of inner coupling, more complicated is adjusted in the bearing assembling.Fit is: respectively the tapered roller bearing outer ring is pressed in the hub seat hole; The interference of neck bearing inner ring is compressed on the axle tag, and the wheel hub that will be pressed into the outer ring again is inserted in the neck bearing inner ring, is pressed into the outer bearing inner ring then; After accomplishing, inside and outside bearing installation also need carry out the adjustment of rotating torque; The assurance bearing clearance is correct, and the assembly maintenance is inconvenient, and maintenance cost is higher.
Summary of the invention
The utility model is to the deficiency of prior art; Provide a kind of to simple in structure, the processing and manufacturing cost is low, do not influence under the prerequisite that realizes the wheel installation function, realizes the technical scheme of the bearing unit and the truck front axle wheel hub structure of brake disc installation through innovative design.
The utility model is realized through following technical measures: a kind of truck front axle wheel hub structure, comprise wheel hub, and said wheelboss inner hole is the single integral body columniform bearing bore coaxial with it, and the integrated shaft bearing unit is installed in the said bearing bore.
The further improvement of the utility model also has, and above-mentioned bearing bore middle part is provided with the bearing shoulder block, and the other end of bearing bore is provided with the hole slot that circlip for bore is installed, and said bearing unit is through bearing shoulder block and circlip for bore axial limiting.
On the above-mentioned wheel hub wheel bolt is installed.
Above-mentioned wheel hub outer edge surface is the stepped appearance face of cylinder, and said wheel hub is equipped with brake disc through bolt.
The beneficial effect of the utility model is: the wheel hub inner chamber is the single single-piece face of cylinder, and processing is simple, has saved productive costs; Wheel hub inner chamber one end is provided with the bearing shoulder block; Be convenient to the bearing unit installing and locating, the other end is provided with hole slot, and mounting hole is used the elasticity circlip for bore; It is spacing to be used for bearing unit; Bearing unit is packed into and need not be carried out the adjustment of rotating torque behind the wheel hub inner chamber, has reduced the production maintenance difficulties, has practiced thrift the production maintenance time; The whole processing in the wheel hub outside ladder face of cylinder, realization is connected with brake disc; Wheel hub and bearing unit, brake disc, wheel bolt link together, and as the branch unit dismounting, have improved the assembly efficiency of assembling.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Among the figure, 1, wheel bolt, 2, bolt, 3, brake disc, 4, wheel hub, 5, bearing unit, 6, circlip for bore.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, through a specific embodiment, this programme is set forth below.
A kind of truck front axle wheel hub structure comprises wheel hub, and 4 said wheelboss inner holes are the single integral body columniform bearing bore coaxial with it; Integrated shaft bearing unit 5 is installed in the said bearing bore; Said bearing bore middle part is provided with the bearing shoulder block, and the other end of bearing bore is provided with the hole slot that circlip for bore 6 is installed, and said bearing unit 5 is through bearing shoulder block and circlip for bore 6 axial limitings; Wherein, Wheel bolt 1 is installed on the wheel hub 4, and wheel hub 4 outer edge surfaces are the stepped appearance face of cylinder, and said wheel hub 4 is installed with brake disc 3 through bolt 2.
The utility model can pass through or adopt existing techniques in realizing without the technical characterictic of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
