Description
Technical field
The utility model relates to technical field of automobile, is specially a kind of automobile front-axle hub.
Background technology
Along with improving constantly of auto manufacturing technology, chassis part also constantly updates as its important component part thereupon.Automotive hub is main security parts on chassis and important link, and front wheel hub is also equipped with brake wheel, ensures the driving safety of automobile and the precise positioning of tire.
Because propons wheel rim bolt mounting holes is larger than wheel bolt cadre size, the two does not contact in fitting process, thus there is certain tolerance clearance, causing tire to be arranged on after on propons can offset up and down, tire centerline can not with front axle steering knuckle center superposition.If this skew is excessive, automobile has operator's compartment sensation one on the other in the process of moving, causes car load to shake.Therefore, need the location adjusting tire in car load dress tire process, by the coaxial level regulating the pretension of each wheel bolt to ensure tire centerline and front axle steering knuckle center.But owing to not easily finding positioning datum, raise whole wheel alignment at car load and seem cumbersome.
And existing automobile, especially heavy motor vehicle, the general inner stopper being all with diameter different in the axial center hole of its front axle hub, for the left and right hub bearing of installation, the front axle hub of this structure needs to come machining center hole from two, processed complex, and the stop portion of the cylindrical of wheel hub and installing wheel is all more roomy, thick and heavy, cause front axle hub rough-cast both to waste material, processing capacity is large again, adds productive costs.
In view of this, special proposition the utility model.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of automobile front-axle hub is provided, wheel alignment can be simplified, improve tire centerline and front axle steering knuckle central coaxial degree, and can time processing shaping and processing is simple, and lighter in weight, labor and material saving, reduces productive costs.
For solving the problems of the technologies described above, the basic conception of the utility model employing technical scheme is:
A kind of automobile front-axle hub, comprises hub body, it is characterized in that: hub body outside face is provided with brake wheel positioning step, brake wheel positioning step is provided with wheel rim positioning spigot; Hub body offers axial central through hole, this axial central through hole is followed successively by left bearing hole section, transitional pore section from left to right, right bearing hole section, mounting hole section and wheel hub cap bore section, this left bearing hole section is identical with the diameter of right bearing hole section, the diameter of transitional pore section is greater than the diameter of left and right bearing hole section, the diameter of mounting hole section is greater than the diameter of right bearing hole section, and this mounting hole section offers jump-ring slot, and the diameter of wheel hub cap bore section is greater than the diameter of mounting hole section.
Further, offer breach equably at the edge of the outside face of hub body to form well-distributed rectangular boss, described rectangular boss all offers bolt hole.
Preferably, described brake wheel positioning step is evenly distributed on the same circle of hub body outside face.
Preferably, described breach is U-shaped breach.
Preferably, the edge of the outside face of hub body arranges ten breach uniformly.
After adopting technique scheme, the utility model compared with prior art has following beneficial effect: the right alignment being ensured wheel rim and wheel hub by the tolerance fit of the wheel rim positioning spigot on wheel hub and wheel rim, and then ensure the right alignment at tire centerline and steering swivel center, both be convenient to assembling, the car load shake caused by both's disalignment can have been improved again; The axial center hole of wheel hub is the step through hole without adduction seam, and be convenient to processing, meanwhile, the breach of setting alleviates the deadweight of wheel hub, but does not affect the intensity of wheel hub, decreases processing capacity, reduces productive costs.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, to help understanding content of the present utility model.
As shown in Figure 1, a kind of automobile front-axle hub, comprise hub body 1, hub body outside face is provided with brake wheel positioning step 2, described brake wheel positioning step 2 is evenly distributed on the same circle of hub body outside face, the head end of brake wheel positioning step 2 is provided with shoulder, forms wheel rim positioning spigot 3; Wheel rim is arranged on this seam, can ensure tire centerline and the coaxial level at steering swivel center, improve the situation of car load shake to a certain extent; The size of the brake wheel that wheel hub assembles and wheel hub matching part must not be less than the size of wheel rim and wheel hub matching part, due to the difference of manufacturing process, two sizes are usually inconsistent, the utility model directly arranges shoulder as wheel rim positioning spigot on brake wheel positioning step, the commonality of product can be ensured, reduce the change of product, take into account the size of brake wheel and wheel rim simultaneously, simplify location structure, enhance productivity; Brake wheel positioning step is evenly distributed on the same circle of hub body outside face, and the installation of wheel hub and wheel rim is stablized.
With reference to shown in Fig. 2, this hub body 1 offers axial central through hole, this axial central through hole is followed successively by left bearing hole section 4 from left to right, transitional pore section 5, right bearing hole section 6, mounting hole section 7 and wheel hub cap bore section 8, this left bearing hole section 4 is identical with the diameter of right bearing hole section 6, be used for corresponding install left, right hub bearing, the diameter of transitional pore section 5 is all greater than the diameter of left bearing hole section 4 and right bearing hole section 6, the diameter of mounting hole section 7 is slightly larger than the diameter of right bearing hole section 6, be beneficial to right hub bearing is installed, simultaneously, this mounting hole section is offered jump-ring slot 9 spacing to right hub bearing to install jump ring, the diameter of wheel hub cap bore section 8 is greater than the diameter of mounting hole section 7, be used for wheel hub cover is installed, breach 10 is offered equably to form well-distributed rectangular boss 11 at the edge of the outside face of hub body, this breach 10 can be U-shaped breach, and be good to offer ten breach on the edge of the outside face of hub body equably, described rectangular boss 11 all offers bolt hole 12, to install bolt installing wheel.
The axial center hole of this automobile front-axle hub is step through hole, and be convenient to processing, meanwhile, the breach of setting alleviates the deadweight of wheel hub, but does not affect the intensity of wheel hub, decreases processing capacity, reduces productive costs
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
