摘要： Systems and apparatuses include a power shift transmission including a plurality of clutch valves, each clutch valve actuatable between an open position providing flow to a corresponding clutch pack and a closed position inhibiting flow to the corresponding clutch pack; and a hydraulic damping rail including a primary rail wall defining a primary rail volume, a rail inlet structured to provide communication of hydraulic fluid between a hydraulic pump and the primary rail volume, and a plurality of rail outlets, each rail outlet corresponding to one of the plurality of clutch valves and structured to provide communication between the primary rail volume and the corresponding one of the plurality of clutch valves.

摘要： An exhaust treatment system for a work vehicle includes a mixing conduit extending between upstream and downstream ends along a bulk flow direction, where the upstream end receives engine exhaust. The system further includes an injector nozzle configured to inject exhaust reductant into the mixing conduit at a location between the upstream and downstream ends. Additionally, the system includes a branch conduit, where an inlet end of the branch conduit is fluidly coupled to the mixing conduit upstream of a location at which an outlet end of the branch conduit is fluidly coupled to the mixing conduit. A portion of the exhaust flowing through the mixing conduit may be directed through the branch conduit, where the outlet end of the branch conduit is configured to direct the portion of the exhaust back into the mixing conduit such that a spiraling flow of the exhaust is generated within the mixing conduit.

摘要： A hydraulic damping rail includes a primary rail wall defining a primary rail volume, a rail inlet structured to provide communication of hydraulic fluid between a hydraulic pump and the primary rail volume, and a plurality of rail outlets configured to provide communication between the primary rail volume and a plurality of clutch valves. A spacing between adjacent pairs of rail outlets of the plurality of rail outlets is variable.
