The difference between electric car wheels and fuel car wheels
There are significant differences between the wheels of plug-in vehicles (i.e. electric vehicles) and the wheels of fuel vehicles, and these differences are mainly reflected in the following aspects:
1. load capacity
Electric vehicle wheels: Because electric vehicles are loaded with heavy battery packs, their maintenance mass is often greater than that of fuel vehicles of the same class. Therefore, electric vehicle wheels need to have a higher load capacity in order to withstand greater weight. For example, the tires of some electric vehicles are designed with a higher load index in mind to ensure safety performance while carrying the weight of the vehicle.
Fuel vehicle wheels: Although fuel vehicles also have a certain weight, they are generally lighter than electric vehicles. Therefore, the load capacity of fuel vehicle wheels is usually designed according to the weight and use needs of fuel vehicles, and the load requirements are lower than that of electric vehicle wheels.
2. Rolling resistance
Electric vehicle wheels: In order to increase driving range, electric vehicle wheels usually need to have lower rolling resistance. Low roll resistance tires can reduce the energy loss of the vehicle during driving, thereby improving the energy efficiency of electric vehicles. Some special tires for electric vehicles use special rubber formulations and patterns to reduce rolling resistance.
Fuel vehicle wheels: Although fuel vehicles also want to reduce rolling resistance to improve fuel economy, due to their different power sources, the requirements for rolling resistance are relatively low for electric vehicles. In the design of fuel vehicle tires, more consideration is given to the performance of grip, handling and other aspects.
3. Mute performance
Electric vehicle wheels: Because electric vehicles do not have the noise of the engine, the interior is relatively quiet, so electric vehicle wheels usually need to have better silence performance to reduce noise during driving. Electric car tires may use special patterns and sound-absorbing materials to reduce the noise caused by tire contact with the road.
Fuel vehicle wheels: Fuel vehicles due to the noise of the engine, the quiet performance of the tire requirements are relatively low. However, as consumers' requirements for driving comfort continue to improve, some high-end fuel vehicles have also begun to be equipped with better quiet performance tires.
4. Wear resistance
Electric vehicle wheels: Due to the high torque characteristics of electric vehicles, the wear when starting and braking is greater than that of fuel vehicles. Therefore, electric vehicle wheels need to have better wear resistance to extend their service life.
Fuel vehicle wheels: Although the wear resistance of fuel vehicle wheels also needs to be considered, the wear situation is usually more gentle compared to electric vehicles.
5. The closed design of the wheel of the plug-in car
Tram hubs are often closed, meaning that the surface of the hub is covered by a sealed housing designed to protect the parts and mechanisms inside the wheel. This design prevents road dust, water vapor and debris from entering the interior of the wheel, thereby reducing friction and wear and improving tire life. In addition, the closed design can also reduce wind resistance, improve driving efficiency, and further reduce the energy consumption of the tram. This not only helps to reduce maintenance costs, but also reduces the production of waste tires, reduces resource consumption, and reduces greenhouse gas emissions such as carbon dioxide.
