Preparation materials: calculation level, 3D drawing software.
1. First, draw the basic shape of the hub. You can draw a circle as the outer boundary of the tire first.
Draw the central part of the hub inside the circle. This is usually a raised area, and the shape and size can be adjusted according to the specific type of wheel hub you draw.
2. Next, according to the design of the hub, draw the details of the bulge and depression. These details can be spokes, threads, patterns, etc. Depending on the type of hub you draw.
Use curves and arcs to connect and define various parts of the hub. Pay attention to the smoothness and symmetry of the curve to increase the realism of the hub.
3. In the process of painting, don't forget to consider the effect of light and shadow. This will help to increase the three-dimensional sense and realism of the hub. Shadows and highlights can be used to highlight the convex and concave parts of the hub.
Finally, check and correct the details to ensure that the shape and details of the hub meet your expectations.
Definition and development of hub
I. Definition
The hub is a cylindrical metal part, the center of which is mounted on the shaft and supported by the inner contour of the tire. Also called rims, rims, wheels and tire bells. There are many kinds of wheels according to their diameters, widths, molding methods and materials.
Second, development.
In the past, the hub bearings of automobiles were mostly paired with single row tapered rollers or ball bearings. With the development of science and technology, automobile hub units have been widely used in automobiles. The application scope and quantity of hub bearing unit are increasing day by day, and it has developed to the third generation.
The first generation consists of double-row angular contact bearings. The second generation has a flange to fix the bearing on the outer raceway, which can simply cover the bearing on the axle and fix it with nuts. It makes the maintenance of the car easy.
The third generation hub bearing unit adopts the cooperation of bearing unit and anti-lock braking system. The hub unit is designed with an inner flange and an outer flange. The inner flange is fixed on the transmission shaft by bolts, and the outer flange installs the whole bearing together.
