Abstract
A fluid arrangement for fluid actuation of at least one clutch and at least one transmission component and including a fluid energy source. The fluid energy source is a fluid pump including a first transport direction, in which the fluid pump serves on a transmission side to actuate the transmission component, and including a second transport direction opposite to the first transport direction, in which the fluid pump serves on a clutch side to actuate the clutch.
Claims2
A fluid arrangement comprising:
- a reversible pump;
- a transmission actuator;
- a transmission hydraulic line connecting the reversible pump to the transmission actuator;
- a clutch actuator;
- a clutch hydraulic line connecting the reversible pump to the clutch actuator
- a first connecting line connecting the transmission hydraulic line to a fluid reservoir;
- a second connecting line connecting the transmission hydraulic line to the fluid reservoir;
- and,
- a dual pressure valve hydraulically connected to the first connecting line, the second connecting line, and the reservoir, wherein:
- the dual pressure valve comprises:
- a first control cylinder hydraulically connected to the first connecting line;
- and,
- a second control cylinder hydraulically connected to the second connecting line;
- the first control cylinder is arranged to connect the second connecting line to the fluid reservoir when operated on by a pressure in the first connecting line;
- and,
- the second control cylinder is arranged to connect the first connecting line to the fluid reservoir when operated on by a pressure in the second connecting line.
