Hydrostatischer Fahrantrieb mit Differentialsperre

摘要

The invention relates to a hydrostatic drive (1) comprising a first hydraulic pump (2) and a second hydraulic pump (3), in addition to a first hydraulic motor (7) and a second hydraulic motor (12), said hydraulic pumps (7, 12) driving separate transmission lines. In a straight driving mode, the hydraulic pumps (2, 3) and the hydraulic motors (7, 12) are coupled in a single closed hydraulic circuit without any crossover lines in such a way that the input terminal (6) of the first hydraulic motor (7) is connected to the output terminal (5) of the first hydraulic pump (2) and the input terminal (9) of the second hydraulic pump (3) is connected to the output terminal (8) of the first hydraulic pump (7). The input terminal (11) of the second hydraulic motor (12) is connected to the output terminal (10) of the second hydraulic pump (3) while the input terminal (14) of the first hydraulic pump (2) is connected to the output terminal (13) of the second hydraulic motor (12).
