| 摘要 |
A hydraulic control system for a machine, the machine having a service brake and a parking brake, includes a hydraulic fluid tank, a pump configured to withdraw hydraulic fluid from the hydraulic fluid tank, and a first accumulator and a second accumulator fluidly connected to the pump. The first and second accumulators configured to supply the hydraulic fluid to the service brake and the parking brake. Further, a resolver valve fluidly coupled between the first and second accumulators and configured to selectively supply the hydraulic fluid from one of the first and second accumulators to the parking brake. |
