HYDRAULIC POWERTRAIN SYSTEMS FOR A VEHICLE INCLUDING HYDRAULICALLY AND AUXILIARY POWERED SYSTEMS AND ACCESSORIES

摘要

A hydraulic auxiliary power system ( 248 ) for a vehicle includes a hydraulic pump ( 28 ). An auxiliary drive motor ( 56 ') receives hydraulic fluid from the hydraulic pump ( 28 ). An electrical current generating device ( 252 ) is coupled to the auxiliary drive motor ( 56 ') and powers one or more mechanically or electrically operated devices ( 254 ). A powertrain system ( 10 ''') includes an engine ( 12 ) and the hydraulic pump ( 28 ). A drivetrain hydraulic motor ( 30 ) receives hydraulic fluid from the hydraulic pump ( 28 ). The drivetrain motor ( 30 ) supplies energy for translation of the vehicle in response to the received hydraulic fluid. The auxiliary drive motor ( 56 ') is in fluid operation with the hydraulic pump ( 28 ) and supplies energy to one or more of the mechanically or electrically powered devices ( 254 ).
