| 摘要 |
The invention relates to a hydrostatic vehicle drive system ( 1 ) comprising a first and a second hydraulic pump ( 2, 3 ), and a first and a second hydraulic motor ( 7, 12 ). Said hydraulic pumps ( 2, 3 ) and said hydraulic motors ( 7, 12 ) are coupled in such a way in a differential lock operation that a first connection ( 14 ) of the first hydraulic pump ( 2 ) is connected to a first connection ( 8 ) of the first hydraulic motor ( 7 ); a second connection ( 6 ) of the first hydraulic motor ( 7 ) is connected to a first connection ( 10 ) of the ( 10 ) of the second hydraulic pump ( 3 ); a second connection ( 9 ) of the second hydraulic pump ( 3 ) is connected to a first connection ( 13 ) of the second hydraulic motor ( 12 ); and a second connection ( 11 ) of the second hydraulic motor ( 12 ) is connected to a second connection ( 5 ) of the first hydraulic pump ( 2 ). The absorption volume of the first hydraulic motor ( 7 ) and the second hydraulic motor ( 12 ) can be respectively adjusted by means of an adjusting device ( 20, 21 ).
