Background technique

Hub The cylindrical metal part in the car tire that is centered on the axle to support the tire. In layman's terms, it is the part where the axle is installed in the center of the wheel. It is an important part that connects the brake drum (brake disc), the wheel disc and the half shaft. . The wheel hub is also called the rim, the wheel, and the tire bell. It is a barrel-shaped, center-mounted metal part that supports the tire on the inner profile of the tire. There are many types of hubs according to diameter, width, molding method and material. The same diameter, but different width, has the opposite, but the two data are different wheels, suitable for different tires. Patent No. 201520312223.1 discloses a shock-absorbing wheel hub that avoids out-of-round or fracture, including a rim and a wheel shaft; the rim and the wheel shaft are connected through spokes; the spokes include a fixed rod and a movable sleeve, and one end of the fixed rod It is fixed on the rim, and the other end slides into the movable sleeve. The end of the movable sleeve away from the fixed rod is fixed on the rim. The outer cover of the fixed rod is provided with a spring. Effect, but this patent also has some deficiencies. The shock-absorbing spring is directly installed on the outside of the hub, which is not only unattractive, but also easily damaged by external factors, which affects the service life of the hub, and the fixed rod and the movable sleeve are slidingly connected, resulting in a loose connection between the outer ring and the inner ring of the hub. easily damaged.
