Hydraulic drive apparatus

摘要

A hydrostatic drive device comprising a hydrostatic transmission mounted in a housing and a single output shaft driven by the hydrostatic transmission and extending out of the housing. The hydrostatic transmission has a center section mounted entirely within the housing and a rotatable hydraulic pump and a rotatable hydraulic motor mounted on the center section and connected through hydraulic porting in the center section. A pump shaft extends into the housing to drive the pump block, and the longitudinal axis of the output shaft is perpendicular to the longitudinal axis of the pump shaft.
