Hydrostatic vehicle drive with differential lock

A hydrostatic vehicle drive with at least a first and a second hydropump (2, 3) and at least a first and a second hydromotor (7, 12), the hydromotors (7, 12) driving separate drive lines in each case, characterised in that

• the hydromotors (7, 12) are double hydromotors, each with two partial hydromotors (7a, 7b;
• 12a, 12b) and
• the hydropumps (2, 3) and the hydromotors (7, 12) are coupled with one another in a closed hydraulic circuit in such a manner that
• a common input connection (6) of the two partial hydromotors (7a, 7b) of the first hydromotor (7) is connected to an output connection (5) of the first hydropump (2),
• an output connection (6a) of the first partial hydromotor (7a) of the first hydromotor (7) is connected to an input connection (9) of the second hydropump (3),
• an output connection (6b) of the second partial hydromotor (7b) of the first hydromotor (7) is connected to an input connection (14) of the first hydropump (2),
• an input connection (11a) of the first partial hydromotor (12a) of the second hydromotor (12) is connected to an output connection (10) of the second hydropump (3),
• an input connection (11b) of the second partial hydromotor (12b) of the second hydromotor (12) is connected to the output connection (5) of the first hydropump (2), and
• a common output connection (13) of the two partial hydromotors (12a, 12b) of the second hydromotor (12) is connected to the input connection (9) of the second hydropump (3).
