Некоторые вопросы диагностики автоматических коробок передач

Abstract

В связи с широким распространением автоматических коробок передач большое значение приобретает доступность услуги диагностики. В условиях отсутствия технических средств диагностики предварительная диагностика может быть осуществлена путём наблюдения за сиптомами при эксплуатации автомобиля. В статье поставлена задача показать на примере конкретной АКП последовательность шагов и необходимый объём предварительных сведений, для разработки и составления матрицы диагностирования распределительного блока.

Due to the wide distribution of automatic transmissions, the availability of diagnostic services is of great importance. In the absence of technical diagnostics, preliminary diagnostics can be carried out by observing the behavior of the transmission during the operation of the car. The aim of the article is to show the sequence of steps and the necessary amount of preliminary information, for the development and compilation of a matrix for diagnosing a distribution block, using the example of a specific automatic transmission system. The distribution block is selected as an object due to the fact that it is characterized by the lowest reliability indicators. The obligatory conditions for the development include the presence of the kinematic scheme of the automatic transmission and the table of active elements in various transmissions. The next step is the collection and systematization of information on the connections of faulty elements and the symptoms of their manifestation. Generalized material is convenient to use as a diagnostic matrix. The matrix proposed here can be used as an auxiliary reference in the diagnostics of a distribution block. When new information appears, the matrix can be expanded in accordance with additional symptoms. Similar matrices can be developed for other models of automatic transmission
