Description
Technical Field
The utility model belongs to the field of aluminum alloy wheel casting, and relates to a high-strength thin-wall windowless cast aluminum alloy wheel structure.
Background
Along with the development of economy and society, people have more and more demands on automobile functions, and in recent years, european and American countries have higher demands on the loading of a pick-up car, and automobile manufacturers design the rear wheels of the heavy-duty pick-up car into double wheels, so that the design can meet the heavy-duty requirements, has attractive appearance and is popular with consumers. The outer wheel in the double wheels has attractive appearance, and the inner wheel has no attractive appearance, but has high strength and light weight. The inner wheel is thin-walled and windowless, most of the wheel is formed by forging, and a cast aluminum alloy wheel structure with high strength and thin wall and windowless is provided.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides a high-strength thin-wall windowless cast aluminum alloy wheel structure, which has the following technical scheme:
a high-strength thin-wall windowless cast aluminum alloy wheel structure is composed of an inner rim, a weight-reducing nest, a rim middle section, a wheel well, a valve hole, an outer rim, a ring groove, a spoke front surface, a wheel front surface mounting surface, bolt holes, a center hole, a flange surface, a spoke back surface, a flange, spokes and a rib part heel.
The joint position of the front face of the spoke and the front mounting face of the wheel is provided with a stress buffering boss, the stress buffering boss is 2mm-5mm higher than the front mounting face of the wheel, and the width is controlled to be 10mm-15mm.
The included angle between the back surface of the spoke and the flange surface is 140-160 degrees, and the diameter of the front surface mounting surface of the wheel is the same as that of the flange surface.
The diameter of the flange face is 35mm-40mm larger than the pitch circle diameter of the bolt hole.
The rib part is designed at the joint position of the middle section of the rim and the wheel well, and the rib part and the wheel well form a ring groove structure.
The utility model has the advantages that: most of the existing thin-wall aluminum alloy wheels are formed by a forging method, and the structure can be produced by a casting method, so that the die cost and the labor cost are greatly reduced, and the structure is high in strength and light in weight.

Fig. 1 is a schematic diagram of the structure of the present utility model.
In the figure: 1. the wheel comprises an inner rim, 2, a weight reducing nest, 3, a middle rim section, 4, a wheel well, 5, a valve hole, 6, an outer rim, 7, a ring groove, 8, a spoke front face, 9, a stress buffer table, 10, a wheel front face mounting face, 11, bolt holes, 12, a center hole, 13, a flange face, 14, a spoke back face, 21, a flange, 22, spokes, 23 and a rib heel.
Detailed Description
The following describes specific embodiments of the present utility model in detail with reference to the drawings.
As shown in fig. 1, the high-strength thin-wall windowless cast aluminum alloy wheel structure is composed of an inner rim 1, a weight-reducing nest 2, a rim middle section 3, a wheel well 4, a valve hole 5, an outer rim 6, a ring groove 7, a spoke front face 8, a wheel front face mounting face 10, a stress buffering boss 9, bolt holes 11, a center hole 12, a flange face 13, a spoke back face 14, a flange 21, spokes 22 and rib parts 23.
The wheel spoke front 8 and the wheel front mounting surface 10 are provided with stress buffering bosses 9 at the joint, the stress buffering bosses 9 are 2mm-5mm higher than the wheel front mounting surface 10, and the width is controlled to be 10mm-15mm.
The included angle between the spoke back surface 14 and the flange surface 13 is 140-160 degrees, and the diameter of the wheel front surface mounting surface 10 is the same as that of the flange surface 13.
The wall thickness ratio of the flange 21, the spoke 22 and the rib part 23 is 1:1.1:1.2, the diameter of the flange surface 13 is 35mm-40mm larger than the pitch circle diameter of the bolt hole 11. Typical pitch circles for bolt holes 11 are 165.1mm, 200mm, 210mm, 225mm.
The thickness of the flange 21 is related to the length of the screw on the axle of the car, and is typically between 12.5mm and 13.5 mm.
The rib part heel 23 is designed at the joint position of the rim middle section 3 and the wheel well 4, and the rib part heel 23 and the wheel well part form a ring groove 7 structure.
The inner rim 1 is provided with a weight-reducing nest 2 in which product information and marks are cast.
The front wheel mounting surface 10 is mounted with the outer wheel, and the surface of the front wheel mounting surface is not allowed to be painted or powdered.
The utility model has the advantages that: most of the existing thin-wall aluminum alloy wheels are formed by a forging method, and the structure can be produced by a casting method, so that the die cost and the labor cost are greatly reduced, and the structure is high in strength and light in weight.
