Disclosure of Invention
The utility model aims to provide a weight-reducing aluminum alloy wheel, which can effectively reduce the overall weight of the wheel, ensure the overall supporting strength of the wheel, give consideration to the modeling of the wheel and adapt to the market demand of attractive appearance and light weight.
In order to achieve the above purpose, the heavy-duty aluminum alloy wheel comprises a rim made of aluminum alloy, a hub and a plurality of spokes, wherein a central hole is formed in the center of the hub, a plurality of bolt connecting holes are uniformly formed around the central hole in a surrounding mode, the hub is positioned at the center of the rim, one end of each spoke is connected to the hub, the other end of each spoke is connected to the rim, the spokes are of an X-shaped structure, an inner hole and an outer hole for reducing weight are formed by matching the hub and the rim, the upper cross point of each spoke is close to the hub, and the size of the inner hole for reducing weight is smaller than that of the outer hole for reducing weight.
As a further scheme of the utility model: the spoke both ends are arc structure, connect the sunken heavy hole that subtracts of one end orientation of hub portion, connect the sunken heavy outer hole that deviates from of one end of rim.
As a further scheme of the utility model: and a weight reduction groove is arranged between the adjacent bolt connecting holes at the back of the hub part.
As a further scheme of the utility model: the hub part is provided with a sinking groove, and the central hole and the bolt connecting hole are both arranged in the sinking groove.
As a further scheme of the utility model: six groups of spokes are arranged, and heat dissipation windows are formed between every two adjacent spokes.
Compared with the prior art, the utility model has the following beneficial effects:
the spoke adopts an X-shaped structural design, forms a weight-reducing inner hole and a weight-reducing outer hole by matching with the hub part and the rim, realizes the design of light weight of the wheel, and ensures the bearing capacity of the wheel by utilizing an X-shaped supporting structure;
both ends of the spoke adopt arc-shaped structural design, so that attractive appearance is formed, and meanwhile, the structural stability and bearing capacity of the whole wheel are ensured;
the weight-reducing groove is designed at the back of the hub part, and the weight-reducing groove is matched with the weight-reducing inner hole and the weight-reducing outer hole to further provide the weight-reducing effect.

In the figure: 1. rim, 2, hub, 3, spoke, 4, weight-reducing outer hole, 5, weight-reducing inner hole, 6, heat dissipation window, 7, heavy groove, 8, bolted connection hole, 9, centre bore, 10, weight-reducing groove.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1, the heavy-duty aluminum alloy wheel comprises a rim 1 made of aluminum alloy, a hub 2 and a plurality of spokes 3, wherein the hub 2 is centrally provided with a central hole 9, a plurality of bolt connecting holes 8 are uniformly and circumferentially arranged around the central hole 9, the hub 2 is positioned at the center of the rim 1, one end of each spoke 3 is connected with the hub 2, the other end of each spoke 3 is connected with the rim 1, the spokes 3 are of an X-shaped structure, the X-shaped structure is utilized to provide good connection support for the hub 2 and the rim 1, the hub 2 and the rim 1 are matched to form a heavy-duty inner hole 5 and a heavy-duty outer hole 4, the whole weight of the wheel is reduced, the light-duty design is realized, the cross point on the spoke 3 is close to the hub 2, the size of the heavy-duty inner hole 5 is smaller than the size of the heavy-duty outer hole 4, and the design that the hole diameter is increased from inside to outside is not only beneficial to the heat dissipation of the system when the vehicle brakes, and is beneficial to reduce the form noise of the wheel, so that the light-duty noise of the wheel is achieved.
In order to strengthen the supporting strength of the spoke 3 and simultaneously maintain the appearance aesthetic property of the structure, both ends of the spoke 3 are arc-shaped structures, one end of the connecting hub part 2 is sunken towards the weight-reducing inner hole 5, and one end of the connecting rim 1 is sunken away from the weight-reducing outer hole 4, so that an arc-shaped connecting supporting effect is formed.
