Abstract
The utility model discloses an automobile hub capable of reducing air resistance coefficient. The automobile hub comprises a hub which is used for installing a tire, a spoke which is arranged between a spoke installation surface and the hub, and a center hole, wherein bolt holes are formed around the center hole; the hub comprises a rim, a hump and a groove bottom, and a valve hole is formed between the hump and the groove bottom; the spoke is eccentric to wards one side of the center hole on the spoke installation surface; an end surface which is formed through plane cutting is arranged on the outer side of the spoke; two arc surfaces are respectively arranged on the two sides of the end surface ,wherein included angles formed between the outer tangent planes and the axis of the hub are different; one side of the arc surface with the smaller included angle faces to the advancing direction of an automobile. Since the arc surface with the smaller included angle faces to the advancing direction of the automobile, the air resistance is reduced, the air pressure on the side with the larger included angle is smaller and the air is driven to flow towards the direction of a brake disc on the inner side; since the spoke is designed to be eccentric towards one side, the air can be enabled to flow towards the outer side of the spoke when the spoke cuts air, the air gap on the outer side of the spoke is larger and the air resistance can be reduced.
Description
Technical field
The utility model relates to a kind of automotive hub, is specially a kind of automotive hub that reduces air resistance coefficient, belongs to vehicular spare parts technical field.
Background technology
Tire itself is software, in tire the drum-shaped of wide support tire, center hub is that the parts that are contained on axle are just wheel hub.Wheel hub can be divided into two large classes by material: steel wheel hub, alloy wheel hub.And alloy material wheel hub has lighter weight, inertia resistance is little, and making precision is high, and the distortion in the time of high speed rotating is little, and inertia resistance is little, is conducive to improve the linear driving performance of automobile, alleviates tire drag, thereby has reduced oil consumption.The heat conductivility of alloy material is again three times of left and right of steel, and thermal diffusivity is good, and for the brake system of vehicle, the heat fade of tire and brake system can play a role.
When windage is Vehicle Driving Cycle, from the resistance of air, general air resistance has three kinds of forms, and the firstth, the resistance that airflow strikes vehicle front produces, just as taking a plank to go against the wind, suffered resistance is nearly all the resistance that airflow strikes produces.The secondth, friction drag, air with streak that vehicle body is the same can produce friction force, but the utmost dispatch that can travel with general vehicle, friction drag is little of almost ignoring.The 3rd is outer form-drag, and in general, when high vehicle speeds, outer form-drag is topmost air resistance source.
Majority pursue complex structure, intensive wheel hub, although really very attractive in appearance, ignore the windage of wheel hub.
Utility model content
The purpose of this utility model is for a kind of automotive hub that reduces air resistance coefficient is provided, to solve the problems referred to above of prior art.
The purpose of this utility model is to be achieved through the following technical solutions:
Reduce an automotive hub for air resistance coefficient, comprise mounting tyre wheel rim, be arranged at spoke and centre hole between spoke installation surface and wheel rim, described centre hole surrounding is provided with bolt hole; Described wheel rim comprises wheel rim, protruding peak and bottom land, is provided with a valve port between protruding peak and bottom land; The one lateral deviation heart of described spoke past centre hole on spoke installation surface; The arranged outside of described spoke forms end face through a plane cutting; The both sides of described end face are respectively outer tangent plane and wheel hub axis angle two cambered surfaces not etc.; The direction that cambered surface one side that angle is less is advanced towards automobile.
Described outer tangent plane and the angle of wheel hub axis are respectively 30 degree and 22 degree.
Angle between described spoke and radius is 5 degree.
The spoke of described right side wheel hub is toward the right side bias of centre hole, and the spoke of left side wheel hub is toward the left side bias of centre hole.
Described spoke inner side end is provided with groove, to alleviate the quality of wheel hub.
The utlity model has following beneficial effect:
1, by form the outer tangent plane cambered surface different from wheel hub axis angle in spoke both sides, and the less cambered surface of the angle direction of advancing towards automobile, windage reduced; The crosswind that angle is larger is pressed less, drives air to flow toward inner side brake disc direction;
2, spoke design, toward a lateral deviation heart, can make spoke in the time of cutting air, and air is along spoke toward flows outside, and the space in spoke outside is larger, can allow air pass through smoothly, reduces windage.

The specific embodiment
Further set forth constructional feature of the present utility model below by specific embodiments and the drawings.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of automotive hub that reduces air resistance coefficient, comprise mounting tyre wheel rim 1, be arranged at the spoke 2 between spoke installation surface and wheel rim 1, and centre hole 3; Described centre hole 3 surroundings are provided with bolt hole 4; Described wheel rim 1 comprises wheel rim, protruding peak and bottom land, is provided with a valve port between protruding peak and bottom land; The one lateral deviation heart of described spoke 2 past centre hole 3 on spoke installation surface; The arranged outside of described spoke 2 forms end face 5 through a plane cutting; The both sides of described end face 5 are respectively outer tangent plane and wheel hub axis angle two cambered surfaces 7 not etc.; The direction that cambered surface 7 one sides that angle is less are advanced towards automobile.
Described outer tangent plane and the angle of wheel hub axis are respectively 30 degree and 22 degree.
Angle between described spoke 2 and radius is 5 degree.
The spoke 2 of described right side wheel hub is toward the right side bias of centre hole 3, and the spoke 2 of left side wheel hub is toward the left side bias of centre hole 3.
Described spoke 2 inner side ends are provided with groove 6, to alleviate the quality of wheel hub.
