ABSTRACT:
A suspension system, in particular for a working machine, such as a tractor or similar device, with a suspension cylinder (10) is subjected to various load pressures (m). The piston slide (12) and rod side (14) of the system may each be connected to a suspension reservoir (16, 18). A locking device (20) locks the suspension and, with an equalization device (28) having a switching valve (48) within the supply device, controls the piston side (12) of the suspension cylinder (10). A pressure supply (P) supplies the system pressure necessary for the suspension system. A pressure equalization of the system to the relevant load pressure can be performed before renewed operation by the equalization device. The equalization device (28) includes a further switching valve (50) within the supply device (30) for control of the rod side (14) of the suspension cylinder (10). A load monitoring device (LS) is connected to parts of the stop device (20). The associated suspension reservoir (16) for the piston side (12) of the suspension cylinder (10) is in a branch (38) of a line (40).
