The invention discloses a method for testing reliability of an automatic transmission parking mechanism, and belongs to the technical field of transmission testing. The method comprises steps of installing an automatic transmission to be tested on a test bench; determining an acting load in the test; and testing the reliability of automatic transmission parking mechanism. According to the invention, the torque required for testing the reliability of the parking mechanism of a real vehicle can be simulated, the real road test condition can be completed on the transmission performance test bench, the test cost can be reduced, the test period can be shortened, and the test safety can be improved.
Description
technical field [0001] The invention relates to a reliability test method for a parking mechanism of an automatic transmission, which belongs to the technical field of transmission tests. Background technique [0002] The parking mechanism is an important component structure of the automatic transmission. During the research and development process of the automatic transmission, the reliability test of the parking mechanism must be carried out to ensure the product quality. [0003] Usually, the reliability test of the parking mechanism is realized by using a real vehicle on a certain slope through manual operation control. Especially in the early stage of product research and development, such operations occupy a considerable part of manpower, material resources and test resources for reliability tests with a long cycle, and there are problems of inconsistency in the operation time and strength of human operations, and there are also certain problems. security risks. Ther...
