BRAKING SYSTEM |
摘要 |
A braking system includes a brake charge module, an accumulator, and a pressure sensor coupled to the accumulator. The braking system further includes a brake actuator to selectively actuate a brake member based on a fluid pressure inside the brake actuator. The braking system further includes a brake valve disposed between the brake actuator and the accumulator. The brake valve is configured to regulate a flow of the pressurized fluid between the accumulator and the brake actuator. The braking system further includes a controller coupled to the pressure sensor and the brake valve. The controller is configured to determine a low-energy state of the accumulator based on the signal from the pressure sensor and maintain at least a pre-determined threshold value of fluid pressure within the brake actuator to retain the brake member at a touch up position with respect to a rotating member. |

1. A braking system comprising:
a brake charge module configured to supply a pressurized fluid; an accumulator configured to store the pressurized fluid therein; a pressure sensor coupled to the accumulator and configured to generate a signal corresponding to a fluid pressure within the accumulator; a brake actuator configured to receive the pressurized fluid from the accumulator and selectively actuate a brake member therein based on a fluid pressure inside the brake actuator; a brake valve disposed between the brake actuator and the accumulator, the brake valve configured to regulate a flow of the pressurized fluid between the accumulator and the brake actuator; and a controller communicably coupled to at least the pressure sensor and the brake valve, the controller configured to:
determine a low-energy state of the accumulator based on at least the signal from the pressure sensor; andmaintain the fluid pressure within the brake actuator above a pre-determined threshold value to retain the brake member at a touch up position with respect to a rotating member. |
