Description

Wheel hub

Technical Field

The utility model belongs to the technical field of the automotive technology and specifically relates to a wheel hub is related to.

Background

The hub is a metal part for supporting the center of the tire, mounting it on the axle. The processing method of the wheel hub mainly comprises forging and casting, the forged wheel hub has light weight, good heat spreading and high strength, but the production process is more complex, and the manufacturing cost of the wheel hub is high; the casting comprises gravity casting, extrusion casting and the like, the gravity casting process is simple, but the strength of the hub is low, the safety is poor, and compared with forging and pressure casting, the extrusion casting has the advantages of simple process, high production efficiency, low manufacturing cost and high structural strength. As shown in attached drawings 1-3 of the prior art, an extrusion casting hub is provided with a first inner cavity 8 and a second inner cavity 9 which are arranged at intervals on one side of the hub, and a third inner cavity 10 and a fourth inner cavity 11 which are arranged at intervals on the other side of the hub, and the bottoms of the first inner cavity 8, the second inner cavity 9, the third inner cavity 10 and the fourth inner cavity 11 are all arc-shaped structures, so that the rolling gas is easy to appear in the casting process, the casting quality is affected, and the problems of speed loss at the arc part, difficulty in manufacturing a mold and the like exist.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned prior art not enough, provide a wheel hub, avoid appearing rolling up gas in the pouring process, reduce the loss of speed of pouring, the mould preparation of being convenient for.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a wheel hub, is including locating the inside centre bore of wheel hub, being located the first inner chamber of wheel hub one side and being located the second inner chamber and the third inner chamber of wheel hub opposite side, the bottom of first inner chamber, second inner chamber and third inner chamber is the plane.

The first inner cavities are uniformly distributed along the circumferential direction of the hub.

The second inner cavity and the third inner cavity are arranged at intervals.

The utility model has the advantages that: make the plane structure with the bottom of first inner chamber and second inner chamber, avoid appearing the roll up gas in the pouring process, reduce the speed loss of pouring, the mould preparation of being convenient for.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 4-6, a wheel hub, including locating wheel hub inside centre bore 2, install the bearing in centre bore 2, still include the first inner chamber 1 that is located wheel hub one side and the second inner chamber 3 and the third inner chamber 4 that are located wheel hub opposite side, be used for alleviateing wheel hub dead weight, avoid local thickness too big loose defect that appears, and can also find the inhomogeneous point of wheel hub quality through the dynamic balancing machine, adjust wheel hub's dynamic balance through increasing or reducing the weight of this position inner chamber for wheel hub vibrates when high-speed motion and reduces, the bottom of first inner chamber 1, second inner chamber 3 and third inner chamber 4 is the plane, avoids appearing the roll up gas in the pouring process, reduces the speed loss of pouring, the mould preparation of being convenient for.

The first inner cavities 1 are uniformly distributed along the circumferential direction of the hub.

The second inner cavity 3 and the third inner cavity 4 are arranged at intervals.

The utility model discloses wheel hub's casting mould is shown in fig. 7, and the lower part of material cup 5 is equipped with feed inlet 51, pours into the casting liquid in the follow feed inlet, is full of whole material cup and expects to say 6 backs when the casting liquid, and 4 movements of tup right extrude the casting liquid to mould 7 in, treat the casting liquid cooling back, and the movable mould of mould 7 is kept away from for the wheel hub mould drops.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
