What kind of oil is rear axle oil?
1 Answers
Rear axle oil is gear oil. Classification of rear axle oil: The oil used in the rear axle of a car is called gear oil, which serves the purposes of lubrication and cooling. Automotive gear oil can be basically divided into two categories: medium-load and heavy-load. Requirements for rear axle oil: The main requirements for gear oil are the ability to form a continuous and tough oil film on the contact surface between teeth, meaning it should have high oiliness, to maintain a resilient boundary oil layer between transmission components, ensuring minimal wear and preventing scratches. Additionally, gear oil should have good viscosity-temperature characteristics to reduce friction losses in the power transmission mechanism, improve transmission efficiency, and ensure easy starting of the car (especially during winter starts).
