Abstract
System for suctioning braking particles from a friction braking system, the suction system including a negative-pressure source, a suction mouth, a pneumatic circuit connecting the suction mouth and the negative-pressure source, and a control unit, the suction system further including a closure unit arranged on the pneumatic circuit, the closure unit being able to isolate at least a first portion of the pneumatic circuit, the control unit being configured to control the closure means according to a predetermined logic in order to isolate the first portion of the pneumatic circuit during certain phases between two actual uses of the negative-pressure source.
Claims17
A system for suctioning braking particles from a friction braking system, the suction system comprising:
- at least one negative-pressure source (1), at least one suction mouth (83), at least one pneumatic circuit (3,3′,30) connecting the suction mouth and the at least one negative-pressure source, and a control unit (6),
- wherein the suction system further comprises closure means arranged on the pneumatic circuit, the closure means being able to isolate at least a first portion of the pneumatic circuit (3), the control unit (6) being configured to control the closure means according to a predetermined logic in order to isolate the first portion of the pneumatic circuit during certain phases between two actual uses of the at least one negative-pressure source, the predetermined logic being such that inside the at least one pneumatic circuit a negative pressure is maintained during deactivation of the at least one negative-pressure source (1).
A method for controlling a system for suctioning friction braking particles from a braking system of a vehicle, the suction system comprising:
- at least one negative-pressure source, at least one suction mouth (83), at least one pneumatic circuit (3,3′,30) connecting the suction mouth and the at least one negative-pressure source, closure means arranged on the pneumatic circuit in order to isolate selectively at least a first portion of the pneumatic circuit (3) with a first valve (51) arranged in the vicinity of the suction mouth and a second valve, and a control unit (6) configured to implement the steps of:
- closing the first valve (51)
- closing the second valve (52),
- so as to isolate the first portion of the pneumatic circuit until the next actual use of the at least one negative-pressure source,
- stopping the activation of the at least one negative-pressure source,
- waiting for a new occurrence of the need to activate the at least one negative-pressure source,
- activating the at least one negative-pressure source,
- opening the first valve (51)
- opening the second valve (52).
