Analysis and Design of Automatic Transmission’ Hydraulic System Based on Logic Analysis

Abstract

Volkswagen AG4 Automatic transmission ,for example , was detailed analyzed by logical method from the shifting operation, interlocking of combining elements and failure protection. Shifting operation must first meet the shifting demand ,mangy oil line criss-cross in the automatic transmission hydraulic system circuit ,in a particular gear ,some components must to be meet bonding requirements interlock between them ,finally ,vehicle need a failure system to protect the oil line to prevent failures in order to travel to the failure of the automatic transmission electronic control system .By analyzing ,design principles and ideas of automatic transmission shift controlling hydraulic system were derived.
