A novel commercial vehicle cab single-torsion-bar zero-pre-deviation front suspension turnover system comprises a torsion bar, the outer side of the torsion bar is sleeved with a turnover support assembly, the two ends of the turnover support assembly are each provided with an inner cylinder, the outer sides of the inner cylinders are sleeved with a front suspension cushion assembly, a sleeve is arranged on the outer side of the front suspension cushion assembly, and the front suspension cushion assembly is sleeved with an outer cylinder. The two sleeves are fixedly connected with the left front suspension support assembly and the right front suspension support assembly respectively, a torsion bar force arm assembly is arranged at the end, close to the right front suspension support assembly, of the torsion bar, a fixing block is arranged on the right front suspension support assembly, a torsion bar force arm positioning hole is formed in the upper end of the fixing block, a guide hole is formed in the middle of the fixing block, and the torsion bar force arm assembly is arranged in the guide hole. And an adjusting bolt is inserted in the middle of the guide hole. The cab front suspension turnover system is not affected by the weight of a cab, the rigidity of a suspension support, the rigidity of a frame and the like, can cope with different whole vehicle configurations, and effectively solves the problem that the cab inclines in the X direction.
