What kind of oil is front axle oil and rear axle oil?
1 Answers
Axle oil is gear oil. Classification of axle oil: The oil used in the rear axle of a car is called gear oil, which serves to lubricate and cool. Automotive gear oil can be basically divided into two categories: medium-load and heavy-load. Requirements for axle oil: The main requirements for gear oil are the ability to form a continuous and tough oil film on the contact surfaces between teeth, meaning it should have high oiliness. This ensures that a resilient boundary oil layer is maintained between the transmission components, minimizing 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.
