Abstract
A hydraulic braking system for a farm tractor or the like comprises a first portion, including members (10, 19) for actuating/modulating the braking and operating with a first hydraulic fluid, and a second portion comprising braking members (F) and operating with a second hydraulic fluid incompatible with the first one. An interface device (20) is interposed between the two portions and is arranged to separate the two portions of the system (1) and to prevent fluid passages therebetween. A method of managing such a braking system (1) is also provided.
Claims8
A hydraulic braking system for a vehicle having safety for an operating machine, wherein the braking system (1) comprises:
- a first portion (10, 19) operating with a first fluid and including a hydraulic control unit (19) for actuating interventions on braking members (F) of the operating machine, and
- a second portion (F) operating with a second fluid incompatible with the first one and including the braking members (F) of the operating machine,
- wherein an interface device (20) is interposed between the first portion (10, 19) and the second portion (F), which device is arranged to hydraulically separate said portions and to prevent fluid passages therebetween, and
- wherein the first fluid is a non-mineral brake liquid and the second fluid is a mineral oil.
A method of managing a braking system (1) of of an operating machine, the method comprising the steps of:
- operating a first portion of the braking system (1) with a first hydraulic fluid;
- and
- operating a second portion of the braking system (1) with a second hydraulic fluid incompatible with the first one,
- and being characterised in that it further comprises the step of:
- hydraulically separating said first and second portions of the braking system (1) by interposing an interface device (20) between said portions of the braking system (1), in order to prevent fluid passages from one portion to the other,
- wherein the first portion of the braking system includes a hydraulic control unit (19) for actuating interventions on braking members (F) of the operating machine, and the second portion includes the braking members (F) of the operating machine, and
- wherein the first and the second fluid are a non-mineral brake liquid and a mineral oil, respectively.
