Abstract
A control device of a multi disc brake having a hydraulic circuit having a supply branch to supply a pressurized fluid to a single-acting hydraulic cylinder of a multi disc brake, a discharge branch selectively connectable to the supply branch to discharge the supply branch, a pump to supply pressurized fluid to the supply branch, a distribution valve to selectively connect the supply branch to the pump and discharge the supply branch, and a check valve arranged along the supply branch downstream of the distribution valve to maintain a given pressure in the hydraulic cylinder. The control device further includes a control unit configured to control the pump and the distribution valve.
Claims15
A control device of a multi disc brake, the control device comprising:
- a control unit;
- and
- a hydraulic circuit comprising:
- a supply branch configured to supply a pressurized fluid to a single-acting hydraulic cylinder of the multi disc brake;
- a discharge branch selectively connectable to the supply branch to discharge the supply branch;
- a pump controlled by the control unit and configured to supply the pressurized fluid to the supply branch;
- a distribution valve controlled by the control unit to selectively connect the supply branch to the pump;
- and
- a check valve arranged along the supply branch downstream of the distribution valve and configured to maintain a determined pressure in the single-acting hydraulic cylinder.
A method for controlling a multi disc brake, the method comprising:
- supplying a pressurized fluid along a supply branch of a hydraulic circuit with a pump;
- supplying, by the pump, the pressurized fluid to a single-acting hydraulic cylinder of the multi disc brake, to the supply branch and through a check valve arranged along the supply branch;
- selectively connecting the supply branch to the pump by a distribution valve;
- and
- controlling, by a control unit, the pump and the distribution valve.
