What is the meaning of wheel rim?
1 Answers
Wheel rim, commonly known as wheel ring, is the component installed around the wheel to support and mount the tire, forming the wheel together with the wheel spokes. The wheel rim and spokes can be integral, permanently connected, or detachable. The wheel hub is the rotating component that connects the wheel and axle, responsible for bearing the load between the tire and axle. The classification of automobile wheel rims is as follows: 1. Deep well rim: This type of rim is integral, with a deep groove in the middle of its cross-section. It has a flanged shoulder for mounting the tire bead, with the shoulder usually slightly inclined towards the center at an angle of 4 to 6 degrees. The maximum diameter of the inclined part is called the tire bead seat diameter. The deep groove in the middle of the cross-section facilitates the mounting and dismounting of the tire; 2. Flat base rim: There are many structural forms of this type of rim. The retaining ring is integral, and an open elastic lock ring is used to prevent the retaining ring from coming off; 3. Split rim: This type of rim consists of inner and outer parts. The width of the inner and outer rims can be equal or unequal, and they are bolted together. When mounting or dismounting the tire, only the nuts need to be removed. The inner rim is made with an integral flange to replace the function of the retaining ring, and the inner rim is welded to the wheel disc.
