The invention discloses a cab full-floatation suspension device, and relates to the technical field of car manufacturing. The cab full-floatation suspension device comprises back-suspension assemblies and two front-suspension assemblies connected through a stabilization rod; each front-suspension assembly comprises a front-suspension lower support with an overturning support at the upper end in a fixed mode, the ends of the stabilization rod are connected with the overturning supports, swing arms are arranged between limiting circular beads on the stabilization rod and the overturning supports, the other end of each swing arm is hinged to a front-suspension upper support, the inner lateral wall of each swing arm is connected with a vertically-arranged front-suspension absorber, and the other end of each front-suspension absorber is connected with the corresponding front-suspension upper support. Each front-suspension upper support comprises a base plate, a lateral plate abutting against the outer lateral wall of a cab longitudinal beam and an ancillary shoring support connected with the corresponding front-suspension absorber, and limiting flanges are arranged at the front end of the cab longitudinal beam. Compared with the prior art, four-point full-floatation suspension is adopted in a heavy-duty commercial vehicle, the vibration isolation effect is good, and the smoothness and the reliability of a cab are relatively good; in addition, the cab full-floatation suspension device is simple and compact in structure, and spatial arrangement space is better saved.
