Description

Technical Field

[0001] This application relates to the field of wheels, and in particular to a wheel. Background Art

[0002] A wheel is a cylindrical metal part that supports the tire inside the tire contour and is centered on the axle. It is also known as a rim, steel rim, wheel, and tire bell, etc. The main function of the wheel is to support and protect the tire, enabling it to be tightly connected to the vehicle axle to ensure the stability and safety of the vehicle during driving.

[0003] The weight of the wheel is related to the model size, material, and design of the wheel. An overly heavy wheel will have an adverse impact on the power performance, handling, stability, comfort, durability, and economic cost of the vehicle.

[0004] The heavier the wheel, the more power the vehicle needs to drive it to rotate. During acceleration, a heavier wheel will consume more energy, resulting in a weakened acceleration performance of the vehicle. An overly heavy wheel will increase the unsprung mass of the vehicle, that is, the mass of the part that does not move with the vehicle's suspension system. The increase in unsprung mass will lead to an increase in the vehicle's fuel consumption. A heavier wheel will change the characteristics of the vehicle's suspension system, making the vehicle's response slower when turning or changing lanes and the handling worse. When driving on an uneven road surface, an overly heavy wheel will exacerbate the vehicle's bumpiness and reduce driving stability. A heavier wheel will accelerate the wear of the suspension system and tires, shorten their service life, and increase maintenance costs. Utility Model Content
