    Abstract: A machine includes a first cylinder coupled to a first wheel and a second cylinder coupled to a second wheel. A first proportional dampening valve fluidly connects to the first cylinder and a second proportional dampening valve fluidly connects to the second cylinder. First accumulators are fluidly connected to the first cylinder and the first proportional dampening valve, and second accumulator(s) are fluidly connected to the second cylinder and the second proportional dampening valve. Additionally, a first proportional flow control valve fluidly connects to the first cylinder and a second proportional flow control valve fluidly connected to the second cylinder. An electronic control module (ECM) communicatively couples to the first proportional flow control valve and the second proportional flow control valve to adjust a ride height of the first wheel via the first cylinder and a ride height of the second wheel via the second cylinder.

    Abstract: A braking system for a machine includes a first valve assembly having a first electronically actuated proportional valve, and a second valve assembly having a second electronically actuated proportional valve. The braking system includes a first pressure sensor and a second pressure sensor disposed downstream of the first and second valve assemblies, respectively. The first and second pressure sensors are configured to determine a first pressure and a second pressure of a braking fluid from the first and second valve assembly. The braking system also includes a controller configured to receive a signal indicative of the first pressure and the second pressure of the braking fluid and compare the first pressure and the second pressure. The controller is configured to selectively actuate at least one of the first electronically actuated proportional valve and the second electronically actuated proportional valve to substantially equalize the first pressure and the second pressure.

    Abstract: A hydraulic circuit includes: a priority valve including a first position and a second position where: the first position includes a first fluid passage and a fixed bypass orifice connected to the first fluid passage; the second position includes a second fluid passage and a variable bypass orifice connected to the second fluid passage. The hydraulic circuit further includes: a first fluid line fluidly connecting the priority valve and a first machine component; a second fluid line fluidly connecting the priority valve and a second machine component; a check valve placed between the priority valve and the second machine component and fluidly connecting the priority valve and the second machine component; an oil passage on the priority valve fluidly connected to one or more machine components other than the first and second machine components; one or more actuators connected to the priority valve; and a control valve communicatively connected to the one or more actuators connected to the priority valve.
