What model of gear oil is used for pure electric vehicles?
1 Answers
Electric vehicles commonly use gear oil with specifications of 75W-90 or 80W-90. The specific model should be determined according to the vehicle's maintenance manual. Below is a detailed introduction to gear oil: Introduction: Gear oil should possess good anti-wear and load-bearing properties along with appropriate viscosity. It should also have excellent thermal oxidation stability, anti-foaming characteristics, water separation performance, and rust prevention capabilities. Since gear loads generally exceed 490 MPa, with hypoid gear surface loads reaching as high as 2942 MPa, gear oil accounts for approximately 6% to 8% of the total lubricant volume. Gear oil is a high-performance lubricant. Performance: Appropriate viscosity and good viscous properties are fundamental characteristics of gear oil. Higher viscosity results in a thicker lubricating oil film and relatively greater load-bearing capacity. Extreme pressure anti-wear performance is the most crucial property and primary feature of gear oil, which prevents tooth surface wear, scuffing, and scoring during operation.
