Description
Technical field
The present invention relates to a kind of mould, more particularly to a kind of rim structure of lightweight wheel hub.
Background technology
For the energy and the consideration of environmental protection, automotive light weight technology has become automaker and autoist is chased after jointly
One of target asked.As one wheel hub of automobile extremely important constituting portion point, light-weighted main object can be turned into naturally.
Mitigate the weight of wheel hub, can not only reduce the running resistance of automobile, reduce oil consumption, also help the steering for improving automobile, acceleration,
The performances such as braking.In order to reach the purpose of wheel hub described in lightweight, mainly there are two kinds of approach at present：The first is to use lightweight
Material, for example with ultrahigh-strength steel plates, the light material such as aluminium alloy, magnesium alloy replaces traditional ferrous materials；It is for second
Optimization, the structure of change wheel hub, reduce the wall thickness of wheel hub, mitigate the quality of the wheel hub to greatest extent.Such as Chinese invention
A kind of lightweight light-alloy wheel disclosed in patent application 200910015384.3, by wheel rim, wheel disc, institute of hub portion group
Into, provided with two annular convex rings on the inside of wheel rim, ring-shaped step of the wheel rim position provided with protrusion of wheel rim.Between two annular convex rings
Wheel rim wall thickness is with respect to the wheel rim wall thickness reduction 5%~20% between wheel rim ring-shaped step and annular convex ring.Using the wheel hub of the structure
It can effectively mitigate wheel weight in the case where meeting wheel using security and reliability energy, effectively reduce oil consumption, improve car
Acceleration and patch ground property.But the wheel rim in above-mentioned patent application 200910015384.3 but have ignored and set examining for valve port
Consider.In order to set the valve port and ensure that the wheel hub can keep dynamic balancing, as depicted in figs. 1 and 2, on the wheel rim 1
Often also need to set bulge loop 3, valve port 30 is set on the bulge loop 3.
The content of the invention
In fig. 1 and 2, there is provided can undoubtedly increase the wall thickness of the wheel rim after the bulge loop to increase the wheel hub
Weight.But how the gas is set on the basis of the wheel hub dynamic-balance is kept in the case where omitting the bulge loop setting
Aperture of door, and make the valve port have enough structural strengths be one very headache the problem of.On inventor solves
State problem once to consider to set a pair of symmetrically arranged boss on the wheel rim, valve is set on a boss wherein
The scheme in hole.So, it can solve well above-mentioned on wall thickness and dynamically balanced problem.But, the setting of a pair of projections
The processing in the wheel hub later stage can be adversely affected.Reason is that hub mold typically has four pieces of side forms, adjacent two-by-two
Die joint is formed between the side form, four die joints are formed altogether.During casting, in the wheel rim lateral surface of the wheel hub
The position of upper four die joints of correspondence forms an overlap respectively.In order to remove the overlap, conventional method is the wheel
Hub, which is placed into rotating shaft and driven by rotating shaft, to be rotated at a high speed, and then cutter is fitted on the wheel rim, high in the wheel hub
Deburring is gone during speed rotation.And in order to avoid the boss is also machined away, it is necessary to knife during deburring is gone
Tool avoids the boss.The circle tape cast face where the boss can so be caused（That is mark 20 is defined in Fig. 3
Face）Need to process by human hand in the later stage.Due to the precision problem that human hand is processed, tend not to completely remove overlap completely,
But also obvious cutter trade can be left.As can be seen here, the plan of establishment also imperfection of bulge loop is replaced using boss.The present invention
People is necessary to be improved further this scheme.After multiple experiment and improvement, the present inventor proposes more perfect light
Quantify the rim structure of wheel hub, including the wheel rim that annular is set, it is characterised in that four edges are provided with the lateral surface of wheel rim
Circumferencial direction is uniformly distributed and radially raised boss, and four boss all have basically identical size
And be all located on same radial cross-section, it is provided with valve port on a boss wherein.
Further technical scheme is also possible that the lateral surface of the boss is set to withdrawing pattern inclined-plane.
Further technical scheme is also possible that the circumferential width of the boss is 28~50mm.
According to above-mentioned technical proposal it can be found that the advantageous effects of the present invention are：Due to the lateral surface in wheel rim
On be provided with four and be distributed uniformly and circumferentially and radially raised boss.So, in the mistake of design hub mold
Cheng Zhong, four die joint positions for specially four boss being corresponded to respectively hub mold are set, and allow the shape in casting process
Four overlaps section on a circle tape cast face where boss described in Cheng Yu is respectively fallen on four boss, without falling
Onto the other positions in the tape cast face.It is possible thereby to be offered convenience for the processing in later stage.During going deburring, knife
Tool one of them described boss that can fit is set, and then allows the wheel hub to rotate at a high speed, during rotation, and cutter can be with
Disposably the overlap on four boss is machined away.The human hand processing in later stage can be so reduced, the processing of the wheel hub is improved
Efficiency.But also it is avoided that the cutter trade carried over is processed by human hand influences the outward appearance of the wheel hub.In addition, with four
The boss substitutes existing bulge loop, can mitigate the weight of wheel hub, while can keep the dynamic balancing of the wheel hub again.
Because the present invention has on These characteristics and advantage, the rim structure that lightweight wheel hub is may apply to for this.

Embodiment
The structure to the rim structure of the lightweight wheel hub of application technical solution of the present invention makees further below in conjunction with the accompanying drawings
Explanation.
As shown in Figure 3 and Figure 4, the rim structure of lightweight wheel hub 1 includes the wheel rim 3 that annular is set, in the wheel rim 3
Four are provided with lateral surface to be distributed uniformly and circumferentially, and radially raised boss（4th, 41,42 and 43）.Four
The boss（4th, 41,42 and 43）All there is basically identical size, their circumferential width L is 28,30,35,40,45
Or 50mm.Four boss（4th, 41,42 and 43）It is all located on same radial cross-section 0-0.Wherein on a boss 4
It is provided with valve port 40.In addition, for the ease of the demoulding, the boss（4th, 41,42 and 43）Lateral surface 401 to be set to withdrawing pattern oblique
Face, drafting angle a is not less than 10 degree.
As shown in figure 4, hub mold includes four pieces of side forms（5th, 51,52 and 53）, formed between two pieces of adjacent side forms point
Type face, respectively die joint（A, b, c and d）.During hub mold is designed, specially four boss（4、41、42
With 43）Four die joints of hub mold are corresponded to respectively（a、b、c、d）Position set, allow be formed in casting process it is described convex
Platform（4th, 41,42 and 43）Four overlaps section on the one circle tape cast face 20 at place respectively falls in four boss（4、41、
42 and 43）On, without falling in the other positions in the tape cast face 20.It is possible thereby to be brought just for the processing in later stage
Profit.During going deburring, cutter can fit one of them described boss（4th, 41,42 or 43）Set, then allow described
Wheel hub 1 rotates at a high speed, during rotation, and cutter can be disposably four boss（4th, 41,42 and 43）On overlap add
Work is fallen.The human hand processing in later stage can be so reduced, the processing efficiency of the wheel hub is improved.But also be avoided that and added by human hand
The cutter trade that work is carried over influences the outward appearance of the wheel hub.In addition, with four boss（4th, 41,42 and 43）Substitute existing
Some bulge loops, can mitigate the weight of the wheel hub 1, while can keep the dynamic balancing of the wheel hub 1 again.
