The invention discloses a double-rear-axle air suspension system and a commercial vehicle, and relates to the field of air suspensions, the air suspension system comprises four suspension assemblies, and the four suspension assemblies are arranged on the two sides of double rear axles respectively; each suspension assembly comprises a guide arm, an air bag and a connecting support. The distance between the axis of the drive axle body and the adjacent connecting bracket and the distance between the axis of the drive axle body and the adjacent airbag axis are A1 and B1 respectively; the distance from the axis of the active steering axle body to the adjacent connecting bracket and the distance from the axis of the adjacent air bag are A2 and B2 respectively; the ratio of the bearing capacity of the corresponding air bag of the driving axle body to the air pressure is k1, and the ratio of the bearing capacity of the corresponding air bag of the active steering axle body to the air pressure is k2; the load distribution ratio of the drive axle body to the active steering axle body is k1 (A1 + B1)/A1 to k2 (A2 + B2)/A2. According to the air suspension system and the commercial vehicle, the problem that load distribution of a traditional suspension system cannot be adjusted for a long time and cannot be adjusted in a large proportion is solved.
