Abstract

The invention discloses a kind of automotive wheel reducing air resistance coefficient, comprise the wheel rim of mounting tyre, be arranged at spoke between spoke installation surface and wheel rim and centre hole, described centre hole surrounding is provided with bolt hole; Described wheel rim comprises wheel rim, convex peak and bottom land, is provided with a valve port between convex peak and bottom land; Described spoke is eccentric toward the side of 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 advanced towards automobile in the cambered surface side that angle is less.Due to the direction that the cambered surface that angle is less is advanced towards automobile, reduce windage, the side blast that angle is larger is less, drives air to flow toward brake disc direction, inner side; Spoke design is eccentric toward side, and spoke can be made when cutting air, and air is along spoke toward flows outside, and the space outside spoke is comparatively large, can reduce windage.

Description

A kind of automotive wheel reducing air resistance coefficient
Technical field
The present invention relates to a kind of automotive hub, be specially a kind of automotive wheel reducing air resistance coefficient, belong to technical field of automobile.
Background technology
Tire itself is software, in tire wide support tire drum-shaped, center hub is contained in parts on axle to be 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 make precision high, the distortion when high speed rotating is little, and inertia resistance is little, is conducive to the linear driving performance improving automobile, alleviates tire drag, thus decrease oil consumption.The heat conductivility of alloy material is again about three times 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.
From the resistance of air when windage is vehicle traveling, general air resistance has three kinds of forms, and first is the resistance that airflow strikes vehicle frontal produces, and just as taking one piece of plank to go against the wind, suffered resistance is nearly all the resistance that airflow strikes produces.Second is friction drag, and air is the same with streaking vehicle body can produce friction force, but with the utmost dispatch that general vehicle can travel, friction drag is little of almost ignoring.3rd is outer form-drag, and in general, during high vehicle speeds, outer form-drag is topmost air resistance source.
Majority pursue complex structure, intensive wheel hub, although really very attractive in appearance, have ignored the windage of wheel hub.
Summary of the invention
The object of the invention is to provide a kind of automotive wheel reducing air resistance coefficient, to solve the problems referred to above of prior art.
The object of the invention is to be achieved through the following technical solutions:
Reduce an automotive wheel for air resistance coefficient, comprise the wheel rim of mounting tyre, be arranged at spoke between spoke installation surface and wheel rim and centre hole, described centre hole surrounding is provided with bolt hole; Described wheel rim comprises wheel rim, convex peak and bottom land, is provided with a valve port between convex peak and bottom land; Described spoke is eccentric toward the side of 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 advanced towards automobile in the cambered surface side that angle is less.
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 wheels is eccentric toward the right side of centre hole, and the spoke of left side wheel is eccentric toward the left side of centre hole.
Described spoke inner side end is provided with groove, to alleviate the quality of wheel hub.
The present invention has following beneficial effect:
1, by forming the outer tangent plane cambered surface different from wheel hub axis angle in spoke both sides, and the direction that the less cambered surface of angle is advanced towards automobile, reduce windage; The side blast that angle is larger is less, drives air to flow toward brake disc direction, inner side;
2, spoke design is eccentric toward side, and spoke can be made when cutting air, and air is along spoke toward flows outside, and the space outside spoke is comparatively large, and air can be allowed to pass through smoothly, reduces windage.
Accompanying drawing explanation
Fig. 1 is the structural representation in front of the present invention;
Fig. 2 is the negative structural representation of the present invention;
Fig. 3 is radial section structural representation of the present invention;
Fig. 4 is that the A-A of Fig. 1 is to cross-sectional view;
In figure: 1, wheel rim 2, spoke 3, centre hole 4, bolt hole 5, end face 6, groove 7, cambered surface.
Detailed description of the invention
Constructional feature of the present invention is set forth further below by specific embodiments and the drawings.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of automotive wheel reducing air resistance coefficient, comprises the wheel rim 1 of mounting tyre, is arranged at spoke 2 between spoke installation surface and wheel rim 1, and centre hole 3; Described centre hole 3 surrounding is provided with bolt hole 4; Described wheel rim 1 comprises wheel rim, convex peak and bottom land, is provided with a valve port between convex peak and bottom land; Described spoke 2 is eccentric toward the side of 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 advanced towards automobile in cambered surface 7 side that angle is less.
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 eccentric toward the right side of centre hole 3, and the spoke 2 of left side wheel hub is eccentric toward the left side of centre hole 3.
Described spoke 2 inner side end is provided with groove 6, to alleviate the quality of wheel hub.
