The invention discloses an automobile suspension
system. The automobile suspension
system comprises a hub, a suspension
control arm and a transmission shaft, wherein the transmission shaft is located at the center of the hub, the suspension
control arm comprises a push arm, an upper arm, a short arm and a lower arm, and the push arm perpendicular to the upper arm is used for supporting the weight of an automobile body. The upper arm is of an A shape and is fixed to a frame and the hub through a hard
bushing. The lower arm is of an H shape, the two ends of the first end face of the lower arm are respectively fixed to the frame through hard bushings, a first end point of the second end face of the lower arm is fixed to the hub through a hard
bushing, the first end point of the second end face of the lower arm and the transmission shaft are located in a same perpendicular line, a second end point is connected with the bottom end of the short arm through a soft
bushing, and the top end of the short arm is fixed between the lower arm and the upper arm through a
soft liner. The automobile suspension
system has the advantages that connection accuracy of the upper arm and the automobile body is guaranteed, the capacity for buffering the
impact of a bumpy road on the lower arm is improved, both
engine power and
brake resistance act on the lower arm, longitudinal stress of the upper arm is eliminated, and the requirement for longitudinal rigidity of the automobile body is greatly lowered.
