Abstract
The invention discloses a balance suspension system of a heavy-duty automobile, which comprises supports and balance shafts, the balance suspension system further comprises a middle communicating shaft for connecting the middle parts of the two brackets, the middle communicating shaft is connected with the two supports through a connecting device, and two balance shafts are respectively arranged on the two supports. The balance shaft omits an intermediate bent part at the middle part of an original integral balance shaft and becomes into two independent balance shafts, thereby not only reducing the weight of the balance shafts, but also reducing the processing difficulty of the balance shafts, changing the stress structure of the balance suspension and reinforcing the bearing capacity of the balance suspension system. The two supports are connected through the intermediate connecting shaft, and the balance shafts and the middle communicating shaft are easy to process, so no special equipment is needed. Besides, the balance shafts and the middle communicating shaft are easy to assemble without generating an improper assembly angle phenomenon, thereby avoiding the defect that the balance shafts rotate to interfere with a transmission shaft.
