The utility model relates to the suspension technology of heavy truck cabs, in particular to an integrated cab rear suspension assembly. The integrated cab rear suspension assembly solves the technical problems that the leftward and rightward inclination range of a traditional floating type suspension system is wide and the riding comfort is not high. The integrated cab rear suspension assembly comprises a pair of suspension lower supports fixed to a left longitudinal beam and a right longitudinal beam of a frame respectively. Supporting beam plates are fixed to the tops of the two rear suspension lower supports in an inclined mode respectively. The adjacent sides of the top ends of the two supporting beam plates are connected through a beam assembly. Lateral pull arm assemblies are fixed to the sides, away from each other, of the top ends of the two supporting beam plates respectively. The lateral pull arm assemblies and the supporting beam plates are connected in a rotating mode. A rear suspension shock absorber is arranged between the lower portion of the other end of each lateral pull arm assembly and the bottom of the corresponding beam plate connected with the lateral pull arm assembly. A cab locking assembly used for connecting a cab is fixedly arranged on the upper portion of the other end of each lateral pull arm assembly.
