The invention discloses a flexible connection structure for an auxiliary frame and a chassis beam. The flexible connection structure comprises the chassis beam and the auxiliary frame positioned above the chassis beam, the auxiliary frame comprises two longitudinal beams and a transverse beam, the two longitudinal beams are arranged along the length direction of a carriage, the transverse beam is connected with the two longitudinal beams, the distance between the two longitudinal beams is larger than the width of the chassis beam, the auxiliary frame is hinged to the chassis beam, a supporting structure is arranged on the chassis beam and provided with supporting points with supporting actions for the longitudinal beams of the auxiliary frame, and the auxiliary frame constantly keeps balance under the supporting action of the supporting structure when the chassis beam rotates around a hinge point, so that the hinge point and the supporting points acted by the supporting structure form torsion balance. When a vehicle drives, even if the vehicle drives on a severe road condition, the chassis beam swings along with the height of the road surface, the auxiliary frame and the portion positioned above the auxiliary frame keep relative balance, impact force is greatly reduced, and twisted damage to a vehicle body is reduced.
