Description

Automatic gearbox oil automatic replacement cleaning maintenance method and system
Technical Field
The invention relates to the technical field of vehicle maintenance, in particular to an automatic gearbox oil replacing, cleaning and maintaining method and an automatic gearbox oil replacing, cleaning and maintaining device.
Background
After the automobile runs for a certain distance (6 to 8 kilometers), the Automatic Transmission Fluid (ATF) of the automobile can deteriorate and lose part or all of the original functions (such as lubrication, cooling, torque Transmission and the like), so that the normal operation of the Automatic Transmission is influenced, and the problems of unsmooth gear shifting, overheating of the Transmission and the like are caused.
In order to prolong the service life of the automatic transmission without affecting the running performance of the vehicle, it is necessary to perform oil change maintenance on the automatic transmission. The existing oil change maintenance methods mainly comprise the following two methods:
(1) oil change by a gravity method: by opening the cover plate of the bottom shell of the automatic gearbox, oil in the automatic gearbox flows out of the automatic gearbox by the gravity action. The biggest shortcoming of the scheme is that at least more than half of old oil in the automatic gearbox can be remained in the automatic gearbox and cannot be discharged due to the fact that the internal structure of the automatic gearbox is very precise and complex, so that new oil added at the back can be polluted, and the whole oil changing and maintaining effect is poor.
(2) Oil change is supported by external equipment: in the automobile maintenance market, the maintenance equipment used for replacing the oil of the automatic gearbox is a circulator or an oil replacement cleaning machine. In the process of replacing the automatic gearbox oil by using the oil changing cleaning machine, the pressure generated by the oil changing cleaning machine is combined with a circulating pressure system in the automatic gearbox of the automobile, so that new oil can be injected into the gearbox while old oil is discharged, and dynamic circulation oil changing is realized. However, the existing maintenance equipment for the oil change cleaning machine has the following disadvantages:
(a) the process of replacing the oil of the automatic gearbox cannot be accurately and quantitatively controlled, such as the discharged old oil quantity, the new oil quantity injected into the automatic gearbox, the temperature setting control of the oil of the gearbox and the like;
(b) the oil change process and the result are judged manually, so that the oil change process is inaccurate, errors are easy to occur, and the problems of excessive oil injection or insufficient oil injection amount are easy to occur;
(c) the oil change cleaner device cannot provide information such as automatic transmission information, an automatic transmission oil number and the like corresponding to a vehicle requiring the automatic transmission to be changed for a device operator. The operator is required to look over the automobile maintenance manual, the process is slow, negligence is easy to occur, and the problems of oil adding, mistake oil and the like are easy to occur;
(d) the port of the cleaning equipment needs to be replaced by a joint adapter to be connected with an oil pipe joint on a cooling circulation system of an automatic gearbox of an automobile, but the types of the automatic gearbox are different due to different vehicle types, the types of the automatic gearbox are different, and the oil pipe joints are also various and have no standard, so that the joint adapters of various types are needed;
(e) the oil change cleaning machine equipment has no data storage and query functions in the whole oil change process, no networking function and no cloud platform database.

And S204, the control panel drives the detection device to extract the old oil sample from the old oil tank and detect the old oil sample so as to acquire the oil state of the old oil sample.
The oil quality state includes viscosity information and impurity information.
It should be noted that, in the process of long-term running of the vehicle, a certain amount of impurities (such as metal chips, abrasive particles and the like) are accumulated in the wall, the pipeline and the old oil of the automatic transmission, so that the viscosity of the old oil is increased; after the circulation cleaning, the impurities in the box wall and the pipeline can be mixed with the old oil, so that the impurity content in the automatic gearbox can be effectively detected. Therefore, the states of the automatic transmission and the old oil can be effectively judged by detecting the viscosity information and the impurity information of the old oil subjected to the circular cleaning.
