Description
Technical Field
The utility model belongs to the automobile parts field of making relates to a commercial car lightweight aluminum alloy wheel.
Background
The automobile wheel is made of steel, aluminum alloy, magnesium alloy, carbon fiber and the like, and the steel and the aluminum alloy are the mainstream materials of the current automobile wheel. The light weight of the automobile is a trend, and wheels made of aluminum alloy, magnesium alloy and other materials meet the trend and gradually replace steel wheels.
At present, the commercial vehicle mainly uses steel wheels, but with the implementation of GB 1589-. Meanwhile, with the further tightening of the national policy of energy conservation and emission reduction, the popularization and application rate of the aluminum alloy wheel of the commercial vehicle is faster, and meanwhile, higher requirements are provided for the light weight level of the aluminum alloy wheel of the commercial vehicle.
For the aluminum alloy wheel, the weight is one of the particularly important indexes, the weight of the aluminum alloy wheel is reduced, the production cost of the wheel is reduced, and the weight of the whole automobile is reduced; balance is another important index of the aluminum alloy wheel and tire assembly, and in order to keep the appearance of the aluminum alloy wheel, a position for adhering a balance block needs to be reserved at a proper position of the aluminum alloy wheel.
Therefore, it is necessary to research and develop a light aluminum alloy wheel for a commercial vehicle to reduce the weight of the aluminum alloy wheel and to improve the appearance after a balance block is adhered, so as to improve the light weight of the power-assisted commercial vehicle and improve the appearance of the commercial vehicle.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a commercial car lightweight aluminum alloy wheel.
The technical scheme of the utility model as follows:
the commercial vehicle light-weight aluminum alloy wheel mainly comprises an inner side wheel rim, an inner side tire bead seat, a groove bottom, an outer side wheel rim, an outer side tire bead seat, a wind hole, a spoke, a root groove, a flange, a center hole, a bolt hole and a valve hole. Wherein: the root groove is positioned at the corner of the connecting part of the spoke and the outer side tire bead seat, the part of the root groove is provided with an inclined plane at a first balance block sticking position, and the inner wall of the rim corresponding to the inner side tire bead seat is provided with an inclined plane at a second balance block sticking position; the middle position of the groove bottom is the thinnest part of the rim wall thickness, and the rim wall thickness is gradually increased from the middle position of the groove bottom to the left side and the right side.
The width of the inclined plane of the first balance block pasting position and the second balance block pasting position is 20-30 mm, and the roughness of the inclined plane is smaller than Ra1.6.
The wall thickness of the middle position of the groove bottom is 6-8 mm.
Compared with the prior art, the utility model has the following advantage: the wall thickness of the root groove and the rim of the utility model effectively reduces the weight of the aluminum alloy wheel; the balance block is pasted at the root groove, so that the aluminum alloy wheel has a more attractive appearance effect.
Drawings
FIG. 1 is a schematic structural view of a commercial vehicle lightweight aluminum alloy wheel of the present invention;
fig. 2 is the utility model discloses a positive sketch map of commercial car lightweight aluminum alloy wheel.
In the figure: 1. the tire comprises an inner rim, 2, an inner tire bead seat, 3, a groove bottom, 4, a valve hole, 5, an outer tire bead seat, 6, an outer rim, 7, a wind hole, 8, a flange, 9, a central hole, 10, a bolt hole, 11, a spoke, 12, a root groove, 13, a balance block sticking position I, 14, a groove bottom middle position, 15 and a balance block sticking position II.
Detailed Description
The following detailed description is to be read in connection with the accompanying drawings.
As shown in fig. 1 and 2, the light-weight aluminum alloy wheel for the commercial vehicle comprises an inner rim 1, an inner bead seat 2, a groove bottom 3, an outer rim 6, an outer bead seat 5, an air hole 7, a spoke 11, a root groove 12, a flange 8, a center hole 9, a bolt hole 10 and a valve hole 4.
The root groove 12 is positioned at the corner of the connecting part of the spoke 11 and the outer side bead seat 5, the part of the root groove 12 is provided with an inclined plane of a first balance block sticking position 13, the inner wall of the rim corresponding to the inner side bead seat 2 is provided with an inclined plane of a second balance block sticking position 15, the width of the inclined plane of the first balance block sticking position 13 and the second balance block sticking position 15 is 20-30 mm, and the roughness of the inclined plane is less than Ra1.6; the middle position 14 of the groove bottom is the thinnest part of the rim wall thickness, the wall thickness is 6-8 mm, and the rim wall thickness gradually increases from the middle position 14 of the groove bottom to the left and right sides.
Compared with a steel wheel and a common aluminum alloy wheel, the commercial vehicle light-weight aluminum alloy wheel shown in fig. 1 and 2 has the advantages that the weight of the aluminum alloy wheel is effectively reduced due to the root groove 12 and the rim wall thickness, and the balance weight is adhered to the root groove 12, so that the aluminum alloy wheel has a more attractive appearance effect.
