Abstract:
1. Hydrostatic transmission having two bent axis axial piston units which are operated alternately as a pump and as a motor, with the two bent axis axial piston units being mounted in a common-pivotable dual yoke ( 20 ) and being pivotable together with the latter, characterized in that, in order to minimize the dead volumes ( 8 , 9 , 10 , 11 ) of the two bent axis axial piston units, the rotational axes ( 16 , 17 ) of the two bent axis axial piston units are offset with respect to a pivot axis ( 15 ) of the dual yoke ( 20 ) by a magnitude such that, at all pivot angles, power unit pistons ( 6 ), at dead centre, are located in the direct vicinity of a bore end of a cylinder block ( 7 ).
