Patent ID: 8915813

Claim:
A continuously variable hydrostatic transmission ( 10 , 10 ′, 10 ″; 30 , 30 ′) having torque division for a vehicle, the transmission ( 10 , 10 ′, 10 ″; 30 , 30 ′) comprising: a first hydrostatic unit (H 1 ) operating as a pump and a second hydrostatic unit (H 2 ) operating as a motor; a planetary drive ( 12 ), a first shaft (W 1 ) on a drive-input side and a summing means (W 6 ), wherein the power present at the first shaft (W 1 ) is divided by way of the planetary drive ( 12 ) between a mechanical transmission branch (Z 9 , W 2 , Z 1 , Z 2 or Z 10 ) and a hydraulic transmission branch (Z 7 , W 3 , Z 4 , Z 5 , Z 6 , H 1 , H 2 or Z 7 , W 3 , Z 4 , Z 6 , H 1 , H 2 ) formed by the two hydraulically coupled hydrostatic units (H 1 , H 2 ) and is combined again at the summing means (W 6 ), wherein power transmission between the first shaft (W 1 ) and the summing means (W 6 ) can be controlled exclusively by varying the displacements of the hydrostatic units (H 1 , H 2 ).
