Abstract
The utility model discloses an improved cast aluminum alloy wheel. An area of a wheel outer rim which is matched with a tire is still subjected to machining processing so as to obtain an accurate size and a smooth surface. A non-matched area from an inboard tire bead seat to a wheel neck root part is provided with a structure with the combination of a strengthening rib with a casting surface state and a thin wall wheel rim. The improved cast aluminum alloy wheel has the advantages that: weight of the wheel is reduced, fuel is saved, and vehicle discharge is reduced; casting surface small structure is retained in large area on the wheel rim, a mechanical property of a finished rim is enhanced, defects of a pinhole, shrinkage porosity and the like of a wheel rim outer surface are avoided at the same time, air tightness is good, and the wheel is more safe and reliable.
Description
Technical field
The present invention relates to a kind of auto parts and components, relate in particular to a kind of drive disk assembly of car chassis driving system.
Background technology
Wheel is important safety component; Be to install and fix tire and form the zone of confined space with tire, its function is support tire, transfer function power, forms the sealed high pressure space to realize reducing resistance to motion and to slow down road shocks, weaken vibrations with tire.
At present; The aluminum-alloy wheel wheel rim is smooth full machining surface; This smooth wheel rim mechanical structure is bad; And inside and outside both side surface is all carried out machine up makes the tiny premium-quality cast sturcture of wheel rim casting surface be removed, and what cause keeping on the final wheel rim is the not high thick crystalline granular texture of mechanical characteristics, and this also is exposed to rim surface with defectives such as foundry goods in-to-in pin hole, shrinkage defects.Along with the raising that country requires vehicle product quality the raising of motor vehicle for saving energy and reducing emission index and people, specific to the design and the manufacturing of aluminum-alloy wheel, more reasonable structure, the wheel that weight is lighter become the wheel design unmodified to be pursued.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of improved cast aluminum alloy wheel, the reinforced rib that the wheel outer rim is provided with the casting surface state structure that combines with the thin-walled wheel rim.
The concrete mode of the utility model is that machining surface is still adopted in the zone that cooperates with tire on the wheel outer rim, to obtain the surface of accurate dimensions and polishing.The reinforced rib that non-mating area from inboard tire bead seat to the throat root is provided with the casting surface state structure that combines with the thin-walled wheel rim.The said outer rim large tracts of land of the utility model keeps casting surface, but Joint face of a pattern adds form with the employing machine.
The described improved cast aluminum alloy wheel of the utility model; Wheel rim adopts the reinforcing rib structure of casting surface state to make the wheel mechanical structure be optimized; Wheel rim changes the stressed good reinforced rib and the combination of thin-walled sealing rim structure into by traditional flat configuration; This makes wheel wheel rim local thickness under the unabated situation of load level be reduced to by 5mm to be 2.5mm, finally can to make wheel weight saving 8%-20%.The casting surface that keeps makes this zone tiny cast sturcture of high-quality that kept as much as possible; This makes the mechanical characteristics of wheel rim that lifting arranged before; Casting surface also makes the rim for automobile wheel outside face exist the situation of foundry defects such as pin hole, shrinkage porosite to be resolved; Greatly reduce airtight percent of pass like this, improved the safety and the reliability of wheel.
Description of drawings
Fig. 1 is that the axle of the improved cast aluminum alloy wheel of the utility model is surveyed scheme drawing.
Fig. 2 is the generalized section of the improved cast aluminum alloy wheel of the utility model.
Among the figure: the 1-reinforced rib; 2-thin-walled wheel rim.
The specific embodiment
As shown in Figure 1, the reinforced rib 1 that a kind of improved cast aluminum alloy wheel of the utility model, wheel outer rim are provided with the casting surface state structure that combines with thin-walled wheel rim 2.
The concrete mode of the utility model is that machining surface is still adopted in the zone that cooperates with tire on the wheel outer rim, to obtain the surface of accurate dimensions and polishing.The reinforced rib 1 that non-mating area from inboard tire bead seat to the throat root is provided with the casting surface state structure that combines with thin-walled wheel rim 2.The said outer rim large tracts of land of the utility model keeps casting surface, but Joint face of a pattern adds form with the employing machine.
Claims (2)
1. improved cast aluminum alloy wheel is characterized in that: the wheel outer rim is provided with the reinforced rib (1) and thin-walled wheel rim (2) structure combining of casting surface state.
2. according to the said improved cast aluminum alloy wheel of claim 1; It is characterized in that; The reinforced rib of casting surface state (1) and thin-walled wheel rim (2) structure combining are arranged at from wheel rim inner bead seat to throat root position, and machining surface is still adopted in the zone that cooperates with tire on the wheel outer rim.
