The ceramic bearings used in new energy vehicles mainly include the following types:
1. Zirconia ceramic bearings: Zirconia ceramics are widely used in the motor and transmission systems of new energy vehicles due to their high hardness, excellent wear resistance, and low friction coefficient.
2. Silicon nitride silicon carbide ceramic bearings: Silicon nitride silicon carbide ceramic bearings have excellent high-temperature resistance and chemical stability, and can maintain good performance in high temperature, high-speed, and harsh environments, making them very suitable for electric drive systems of new energy vehicles.
3. Ceramic composite bearings: Ceramic composite bearings are bearings made by combining ceramic and metal materials, which can comprehensively utilize the advantages of ceramics and metal to achieve good wear resistance, corrosion resistance, and high-temperature resistance.
The application of these ceramic bearings in new energy vehicles can improve motor transmission efficiency, reduce energy consumption, and enhance the reliability and service life of the entire vehicle.
