Patent ID: 8454467

Claim:
A power split transmission for a motor vehicle, comprising: a mechanical and a hydrostatic power branch ( 3 , 4 ) which are disposed parallel to one another and are in contact via a common drive shaft ( 1 ), wherein the hydrostatic power branch ( 4 ) is composed of hydraulic motor ( 6 ) coupled to a hydraulic pump ( 5 ) and is connected to the drive shaft ( 1 ) via a gear stage ( 7 ), wherein the split power from the mechanical and the hydrostatic power branch ( 3 , 4 ) can be combined in a gear drive ( 13 ) which is disposed on an end face and is connected downstream to an output shaft ( 2 ), wherein the mechanical power branch ( 3 ) is composed of first and second planetary gear assemblies ( 8 , 9 ) having sun gears ( 10 , 12 ), planet gears ( 16 , 17 ), and ring gears ( 21 , 22 ), wherein the sun gear ( 10 ) of the first planetary gear assembly ( 8 ) is placed directly on the drive shaft ( 1 ), while the sun gear ( 12 ) of the second planetary gear assembly ( 9 ) is in contact with the gear drive ( 13 ) via a sun shaft ( 11 ), and wherein the planet gears ( 16 , 17 ) of both gear assemblies ( 8 , 9 ) are disposed coaxially relative to one another and are supported on a common planet carrier shaft ( 18 ), wherein the planet carrier shaft ( 18 ) is supported on a side of the first planetary gear assembly ( 8 ) via a planet carrier ( 20 ) in the ring gear ( 21 ) of the first planetary gear assembly ( 8 ), and can be connected on a side of the second planetary gear assembly ( 9 ) via a clutch ( 19 ) directly to the sun shaft ( 11 ).
