Background
The chassis lubrication system is a very important system of a tractor, and the main function of the chassis lubrication system is to store oil used for chassis lubrication and lubricate various parts (such as gears and the like) in a chassis. When lubricating oil in the chassis lubricating box lubricates the friction surface of each part, the running speed and the temperature of the lubricating oil are increased due to the heat generated by friction and the high-speed rotation of parts such as gears, a large amount of oil vapor and bubbles are generated, and the viscosity of the lubricating oil is changed. On one hand, for some hydraulic systems with hydraulic pressure and chassis sharing oil, the phenomena of cavitation, noise, cavities and the like of hydraulic parts in the hydraulic system can be caused by the foam-containing hydraulic oil, so that the service lives of the hydraulic parts are greatly reduced; on the other hand, the lubricating oil containing foam is not beneficial to lubricating all parts in the chassis, and can not safely lubricate all friction surfaces, so that the service life of all parts in the chassis lubricating system is shortened. And the lubricating oil with bubbles can cause the pressure in the chassis box body to rise, so that the problems of oil leakage, oil bleeding and the like of the respirator occur.
