Problems solved by technology
Because its own structure limits the torsion angle of the torsion bar, the rigidity of the torsion bar will change with the consistency of production and durability, which will cause the torsional force of the two torsion bars to be inconsistent, causing the cab to tilt or drive When the cab is turned over, the turning force will be too large or too small, which will cause difficulty in turning the cab

The invention discloses a double-torsion-rod assembly of an angle-adjustable cab and relates to an overturning system assembly of a commercial vehicle cab. The double-torsion-rod overturning system assembly is mainly used for solving the problem that the double-torsion-rod overturning system assembly of the existing cab is limited by the torsion angle of the torsion rods so as to cause difficult overturning of the cab. The double-torsion-rod overturning system assembly comprises a left suspension bracket, a right suspension bracket, a left overturning force arm, a right overturning force arm,an upper torsion rod, a lower torsion rod, a left overturning bracket and a right overturning bracket. The double-torsion-rod overturning system assembly is characterized by also comprising a left torsion rod force arm and a right torsion rod force arm which are respectively provided with a left inner thread hole and a right inner thread hole, as well as a left adjusting bolt and a right adjusting bolt which are respectively positioned in the left inner thread hole and the right inner thread hole, wherein the left torsion rod force arm and the right torsion rod force arm are respectively coaxial with the left overturning force arm and the right overturning force arm; and the front ends of the left adjusting bolt and the right adjusting bolt abut against one sides of the left overturning force arm and the right overturning force arm respectively. By utilizing the double-torsion-rod overturning system assembly, the cab can be overturned freely; and the double-torsion-rod overturning system assembly has the characteristics that the structure is simple and the operation is convenient.
Description
technical field [0001] The invention relates to an overturning system assembly of a commercial vehicle cab, in particular to an angle-adjustable cab double torsion bar overturning system assembly. Background technique [0002] The existing double torsion bar turning system assembly of the cab of a commercial vehicle includes a left suspension bracket and a right suspension bracket, a left turning arm and a right turning arm, an upper torsion bar and a lower torsion bar, a left turning bracket and a right turning bracket. Because its own structure limits the torsion angle of the torsion bar, the rigidity of the torsion bar will change with the consistency of production and durability, which will cause the torsional force of the two torsion bars to be inconsistent, causing the cab to tilt or drive When the cab is turned over, the turning force will be too large or too small, which will cause difficulty in turning the cab. Contents of the invention [0003] The object of the...
