ABSTRACT

The development of electronic auto-control technology allows automatic transmission of the application in the car becomes more extensive, accurate, rapid and effective detection performance for the automatic transmission of power motor vehicles, economy and security is very important. At present, foreign automobile automatic transmission performance of the detection method is widely used in the actual loading of the road test, but from the test situation, the method of the high cost of long and demanding, which is precisely the shortcomings of teaching can not meet the requirements. To overcome these deficiencies, the achievement of professional teaching in the automotive automatic transmission performance testing on the bench is to achieve a more reasonable choice.

The design is mainly directed against Toyota A340E automatic transmission to start, first of all introduced the A340E automatic transmission's internal structure, working principle and operation. On this basis, a teaching of the automatic transmission for the purpose of test-bed design. For the purpose of teaching it, the test-bed structure is characterized by relatively simple test-bed has a detection terminal and self-diagnostic interface to facilitate the process of teaching to enable students to understand and intuitive fault by setting the hands to strengthen their capacity in order to achieve good teaching effectiveness.
