Hydromechanical drive for use in drive train of agricultural vehicle i.e. tractor, has hydrostatic transmission comprising supporting frame with recess that is opened transverse to shaft, where one of shafts extends through recess

摘要

The drive has a mechanical distribution gearbox arranged between a drive shaft (1) and an output shaft (7). A continuously adjustable hydrostatic transmission works together with the distribution gearbox. A supporting frame (36) of the hydrostatic transmission has a recess (69) opened transverse to the shaft, where one of the shafts extends through the recess. A hydrostatic unit (23) of the transmission is mounted at a side of the recess. The frame is fixed in an outer housing, and forms a flange bearing for accommodating the hydrostatic unit.
