The development of hubTime:2019-05-22 Wheels are to cars what legs are to people. The vehicle in the process of driving will produce transverse and longitudinal load, at the same time with driving torque, braking torque and other forces. So the hub will take a fair amount of the load. With the increasing speed of cars, the requirement of dynamic stability and reliability of wheel hub is also higher and higher. The earliest cars evolved from horse-drawn carriages. In 1886, Mercedes put the engine on a three-wheeled carriage, thus giving birth to the world's first automobile. Similarly, the earliest wheels were inherited from wagons, and as you can see, the dense spokes were characteristic of the hubs of this period. And this period of wheel hub, rim concept is very clear, not as we now say that the hub included the whole part between the tire and the axle. The rim refers to the part that is close to the tire lip, while the hub refers to the part that is covered in the outer layer of the axle. The spokes radiate from the hub to the rim. Rim, hub and spoke are separable, not one. With the development of science and technology and industry, in the late 19th and early 20th centuries, rims, hubs and spokes began to be integrated through the casting process. Hub prices for electric cars With the development of tire technology, slowly began to appear steel (iron) wheel, the earliest steel wheel looks very heavy and plain, appearance is also very ugly. Then in the 1930s, the germans put steel spokes and aluminum rolled rims on cars, laying the foundation for the development of light-alloy wheels (generally aluminum or magnesium). After world war ii, aluminum wheel hubs began to be used in ordinary cars. With the booming development of automobile industry, aluminum alloy wheel is becoming more and more popular. Aluminum alloy wheel hub more and more light, more and more design, more and more beautiful. The beauty of the wheel hub is like the pursuit of beautiful shoes. This led to a number of manufacturers specializing in wheel modification, such as BBS in Germany, HRE in the United States and RAYS in Japan. It's not just about looks. The advantages of aluminum alloy wheel hub over the traditional steel wheel hub are in all aspects. Lighter weight means less weight for the car, which improves acceleration, braking and handling. The damping performance of aluminum alloy is much better than that of steel, and the ride stability, comfort and safety are improved accordingly. At the same time, the heat dissipation is also relatively better, reducing the aging speed of the brake system and tires, as well as the probability of high temperature brake failure for a long time. At present, most models of our cars have adopted aluminum alloy wheels, and from the point of view of manufacturing technology. Also divided into: gravity casting, low pressure casting and forging technology. |
