Angle-adjustable cab double-torsion-bar tilting system assembly

An angle-adjustable cab double-torsion-bar tilting system assembly relates to a cab tilting system assembly of a commercial vehicle, and mainly solves the problem that a cab with the existing cab double-torsion-bar tilting system assembly is difficult to tilt due to limitation on torsion angle of torsion bars. The angle-adjustable cab double-torsion-bar tilting system assembly comprises a left suspension support, a right suspension support, a left tilting force-arm, a right tilting force-arm, an upper torsion bar, a lower torsion bar, a left tilting support and a right tilting support, and is characterized by further comprising a left torsion bar force-arm with a left internally threaded hole, a right torsion bar force-arm with a right internally threaded hole, a left adjusting bolt in the left internally threaded hole, and a right adjusting bolt in the right internally threaded hole. The left torsion bar force-arm and the right torsion bar force-arm are coaxial to the left tilting force-arm and the right til
