In order to solve the problems caused by the use of common gear oil in the wet drive axle, such as abnormal braking noise, excessive braking distance and severe wear of components, the special oil for the wet drive axle is developed in accordance with the new requirements for lubricating oil after the technical upgrade of the drive axle. Based on the actual braking condition of the wet brake, the oil tribology performance of the wet drive axle is tested and studied by using the brake test bench and increasing the energy density to improve the harshness of the braking condition. The results show that the method can distinguish oil with different tribology performance. The developed oil is superior to the reference oil in formulating smoothness, stability and mechanical transmission efficiency, providing better friction retention over long periods of use.
