Description
Technical field
Technical field of automobile parts is the utility model is related to, more particularly to a kind of wheel hub for automobile.
Background technology
Wheel hub is called wheel rim, axle rumble, tire bell, is that wide support the drum-shaped of tire, center are mounted in Automobile shaft in tire
On metal parts, i.e. wheel center installation axletree position, be to connect brake disc, the important spare part of wheel disc and semiaxis.Wheel
Hub is fixedly connected with axletree so that automobile is rotated during traveling by axle drives wheel hub, to realize whole vapour
Wheel tire is rotated, and using caused frictional force when automobile tire and ground progress relative motion, to drive whole vapour
Car is advanced or retreated.
Wheel hub on the market is mainly steel wheel hub, and steel hub manufacturing technology is simple, typically using casting technique, such as aluminium
Alloy wheel hub is typically produced using low-pressure casting process, advantage of lower cost, and anti-metal fatigue is very capable, therefore by
Extensive use is arrived.Air nozzle hole in existing steel wheel hub is typically designed as shown in figure 1, when processing air nozzle hole by gas
Nozzle aperture position increases salient point to realize valve boring positioning, is to easily cause deviation in positioning so that valve because salient point is smaller
Hole off normal in process, influence the outward appearance of wheel hub.And when air nozzle hole is processed, the conventional big footpath of air nozzle hole and casting
Angle between face is bigger than normal, as shown in Fig. 2 can form more burr, it is necessary to manually strike off on air nozzle hole periphery after processing, consumes
Take more cost of labor, the periphery of air nozzle hole is relatively sharp in addition, and attachment that can be to paint produces considerable influence, makes wheel rim
The coating skewness of valve bore region, and then influence the corrosion resistance and service life of wheel rim valve bore region.
Utility model content
In view of the foregoing, the utility model provides a kind of simple in construction, easy to operation, reasonable in design, easy to use
Wheel hub for automobile.
To reach above-mentioned purpose, technical scheme is used by the utility model solves its technical problem：
A kind of wheel hub for automobile, including：Wheel rim, spoke, strengthen rib ring, spacing hole, positioning hole and air nozzle hole；It is described
The wheel rim of cyclic structure is provided with the outer rim of wheel rim side wall, shield tire ear is provided with the outside of the wheel rim；The spoke is set
Between the wheel rim and the reinforcement rib ring；The positioning hole is arranged in the reinforcement rib ring；The spacing hole is arranged on
The center for strengthening rib ring；The air nozzle hole is arranged on the wheel rim, and the air nozzle hole is arranged to tower-like, the gas
Between the angle of the big footpath of nozzle aperture and the casting plane where it is 25 ° -45 °.
Preferably, between the tower-like angle of the air nozzle hole is 8 ° -20 °.
Preferably, the diameter of the air nozzle hole is between 4-40cm.
Preferably, the central shaft of the spacing hole and the center overlapping of axles of the reinforcement rib ring.
Preferably, the positioning hole is arranged to the small hole shape structure of import large outlet.
Preferably, baffle plate is provided with the air nozzle hole, for opening or closing the air nozzle hole, the baffle plate and the wheel
It is slidably connected on the outside of rim side wall.
Due to the utilization of above-mentioned technical proposal, the utility model has following beneficial effect compared with prior art：
A kind of wheel hub for automobile is provided, air nozzle hole is arranged to tower-like, is effectively reduced during automated exchanged cutter
To the deviations of air nozzle hole, it is not in off normal situation in process to make air nozzle hole, avoids wheel hub from producing after processing
Larger difference in appearance；And tower-like air nozzle hole after processing will not be sharp, it is possible to reduce the formation of burr, reduces what is manually struck off
Frequency, product fraction defective is reduced, reduce processing cost；Simultaneously because tower-like air nozzle hole reduces the burr on periphery so that coating
Easily attachment and uniform fold air nozzle hole neighboring area, improve the corrosion resistance and service life of valve bore region.
