If the moving parts of the vehicle are not lubricated timely or fail, the problems of premature and excessively rapid wear and the like of the related parts can occur, and the problems can seriously cause the vehicle to break down in the running process, thereby causing loss to users.
At present, each lubricating point of a refrigerator car chassis is maintained in a mode of manually and regularly injecting grease, and the defects that maintenance time is long, the lubricating condition is not easy to check, too much or too little grease is easy to inject, grease is wasted and the like exist. Particularly, after the refrigerator car is installed with the box body, the lubricating points are arranged below the box body, so that the operation difficulty is increased when grease is filled, and the maintenance time and the cost are increased.
In order to realize the regular and quantitative filling of lubricating grease into the chassis and the upper system of the refrigerator car, prolong the maintenance period of the car and reduce the maintenance difficulty, the embodiment provides a centralized lubricating method, and the specific content of the embodiment is described in detail below with reference to fig. 1 to 4.
