Technical Examples
  1. 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).
