Abstract: A hydrostatic drive (1) with a hydraulic pump (3) and a plurality of hydraulic motors (6-9) that are hydraulically linked with the hydraulic pump (3). One speed sensor (20; 21; 22; 23) each allocated to a respective hydraulic motor (6; 7; 8; 9) and is linked with a control device (24) and detects the speed (n1; n2; n3; n4) of the allocated hydraulic motor (6; 7; 8; 9). Every hydraulic motor (6; 7; 8; 9) is functionally linked with a brake device (26; 27; 28; 29) that in turn is linked with the control device (24). When the speed (n1; n2; n3; n4) of one of the hydraulic motors (6; 7; 8; 9) exceeds a predetermined threshold value (ng), the control device (24) triggers the brake device (26; 27; 28; 29) allocated to the associated hydraulic motor (6; 7; 8; 9).

Abstract: The invention relates to a hydrostatic traveling mechanism (4) that comprises a closed hydraulic circuit (6) in which a first hydraulic pump (4) with a first hydraulic engine (12) is linked with a flow pipe (7) and a return pipe (8). Said hydraulic engine (12) drives the vehicle wheels (14, 15, 18, 19) of two first vehicle axles (17, 20). According to the invention, an additional open hydraulic circuit (9) is used in which a second hydraulic engine (22) and a third hydraulic engine (24) are linked with a second hydraulic pump (5) via a supply pipe (11) and a control valve (21). Said second hydraulic engine (22) and said third hydraulic engine (24) drive the vehicle wheels (23, 25) of a second vehicle axle (36).
