Abstract:
A fluid system for a continuously variable transmission includes a first pump, a first actuation unit, a first line section, a second actuation unit, and a second line section. The first pump has a first sub-pump and a second sub-pump. The first actuation unit is assigned to a first disc set of the continuously variable transmission and the second actuation unit is assigned to a second disc set of the continuously variable transmission. The first line section fluidically connects the first pump to the first actuation unit and the second line section fluidically connects the first pump to the second actuation unit. The second sub-pump has a first connection that can be selectively fluidically connected to the first actuation unit via the first line section, or the second sub-pump has a second connection that can be selectively fluidically connected to the second actuation unit via the second line section.
