Research Of The Hydraulic Control System Of Automatic Transmission

With the popularity of automatic transmission in the car on the application, the repairwork will also grows with each passing day. However, it is not clear the structure ofautomatic transmission for some engineers. That leads to a low level of automatictransmission. Therefore，the key of the research is to master the construction of AT andthe principle of hydraulic control system. To improve the research capacity and repaircapacity of the AT requires considerable speculative knowledge.Hydraulic control system is the most important as well as the most complicated part inthe automatic transmission. Through summarizing the achievement of the former researchand repeated tests, This paper had accomplished the researchful task of the AT hydraulicsystem, and had determined the basic composition and Integrity analysis method of AThydraulic system. In the paper, the basic expression and analysis method of oil is set up.The paper expounds detailed4T65E, use Photoshop software, and renders the4T65E gearoil circulation chart. In the end, on the basis of analysis of hydraulic control system, thepaper researches on the fault diagnosis method, Put forward systematical analysis, andthrough the actual case, the method is proved to be feasible and practical.In the paper, from the actual needs, the AT hydraulic control system and related circuitis mainly researched, the circuit diagram is drawn by using Photoshop software, andthrough the relevant testing, the system analysis method is verified to be feasible. Thepaper has great significance in guiding practice.
