Abstract
Power takeoff lubrication devices and methods are disclosed. Embodiments include an accumulator connected to a power takeoff fluid supply line and storing fluid (which may be under pressure) for selective use independent of the fluid being supplied by the fluid supply line. In some embodiments, the fluid in the accumulator is supplied to various components within the power takeoff, including the clutch plates (which may have fluid supplied prior to and/or during engagement), which can decrease wear and/or clutch temperature. In some embodiments, the fluid in the accumulator is supplied to the clutch piston to actuate the clutch piston when the pressure in the supply line is less than optimal and/or to stabilize the pressures in the hydraulic lines connected to the clutch piston. In still further embodiments, the fluid in the accumulator is supplied to the clutch when the fluid supply line pressure is less than optimal.
