The invention provides an auxiliary-frame installation assembly. The auxiliary-frame installation assembly comprises an auxiliary-frame connecting lining and an auxiliary-frame fixing bolt, and further comprises a lining installation structure. A rubber body of the auxiliary-frame connecting lining is wrapped by an outer sleeve. The lining installation structure comprises a flange face bolt, an outer mat cover provided with a first matched part and a second matched part and an inner pressing cover provided with a second through hole, wherein a first through hole is formed in the first matched part. A limiting cavity is formed between the first through hole and the second through hole, and the flange face of the flange face nut is located in the limiting cavity. The rubber body of the auxiliary-frame installation assembly is located between the outer sleeve and the outer mat cover, and vibration transmitted from a frame is easily buffered; the deformation amount of the auxiliary-frame connecting lining can be controlled by the outer mat cover, changes in the rigidity of the auxiliary-frame connecting lining are accordingly controlled, the vehicle traveling smoothness is improved, and efficiency losing of the auxiliary-frame connecting lining is effectively prevented; in addition, the vibration transmitted from the frame is better reduced easily through the limiting cavity, and the vehicle traveling smoothness is further improved.
