    摘要: A dual pump apparatus for use on a vehicle or industrial application having a housing in which a pair of hydraulic pumps are mounted, having by at least one charge pump mounted on an end cap, and the trunnion arms for controlling the hydraulic pumps extending out of opposite sides of the housing. A cooling fan may be mounted on the primary or secondary input shaft on the opposite side of the pulley used to engage the prime mover. An auxiliary pump may also be mounted on the primary input shaft and may be located either at the input end thereof adjacent to the pulley, or on the opposite side of the housing.

    摘要: A dual pump apparatus for use on a vehicle or industrial application and having a pair of hydraulic pumps that are disposed in separate chambers within a housing. A pair of input shafts are disposed within the housing to drive the respective hydraulic pumps and one of the input shafts engages a prime mover. A charge pump may be mounted on an end cap, and trunnion arms for controlling the hydraulic pumps may extend out of opposite sides of the housing. An auxiliary pump may also be mounted on one of the input shafts and may be located either at the input end thereof or on the opposite side of the housing.

    摘要: An assembly and means for cooling a hydraulic pump comprising an electric fan mounted on a housing of the hydraulic pump. An upper shroud helps direct cooler air to the fan and helps prevent inadvertent contact with the fan blades. An optional controller can be attached that senses the temperature of the hydraulic pump and adjusts the speed of the fan accordingly.
