Flow system for infinitely adjustable gearbox

摘要

The invention relates to a fluid system (1) for a continuously variable transmission (2), comprising a first pump (3), wherein a first connection of the first pump (3) is fluidically connected via a first line section (4) to a first actuation unit (6) assigned to a first disc set (5) of the transmission (2), and a second connection of the first pump (3) is fluidically connected via a second line section (7) to a second actuation unit (9) assigned to a second disc set (8) of the transmission (2), wherein the first pump (3) is formed by at least one first sub-pump (10) and a second sub-pump (11), wherein a first connection (12) of the second sub-pump (11) can be selectively fluidically connected to the first actuation unit (6) and/or a second connection (14) of the second sub-pump (11) can be selectively fluidically connected to the second actuation unit (9).
