HYDRAULIC SYSTEM OF TRANSMISSION

摘要

PURPOSE: A hydraulic system for a transmission is provided to minimize residual pressure occurred in a confluent circuit by using a brake or a clutch. CONSTITUTION: A hydraulic system for a transmission comprises a first supply flow path(102), a second supply flow path(122), a first branch flow path(104), a second branch flow path(124), and a confluent flow path, and a check valve(105). The first supply flow path transfers hydraulic pressure from a first FSV(100) to a brake(110). The second supply flow path transfers hydraulic pressure from a second FSV(120) to a clutch(130). In the first and the second branch flow path is the first supply flow path and the second supply flow path, it is respectively branched. The first and second branch flow paths are branched from the first and second supply flow paths. The confluent flow path joins the first and second branch flow paths.
