Adjustable cab double-torsion-bar turnover mechanism and assembling method

Abstract

The invention provides an adjustable cab double-torsion-bar turnover mechanism and an assembling method. A cab can be turned over conveniently and rapidly. The adjustable cab double-torsion-bar turnover mechanism comprises a support set, an adjustment set, a torsion arm set and a torsion bar set, and the adjustment set comprises a left adjustment plate assembly, a right adjustment plate assembly, a left adjustment bolt and nut assembly and a right adjustment bolt and nut assembly. The torsion arm set can freely rotate in the circumferential direction relative to the torsion bar set, and the axial position of the torsion arm set is fixed. The assembling method includes the following steps of assembling the support set, assembling the adjustment set and assembling the torsion bar set.

Description

technical field [0001] The invention relates to an overturning system of a truck cab, in particular to an adjustable cab double torsion bar overturning mechanism and an assembly method. Background technique [0002] At present, when domestic trucks adopt the double torsion bar turning mechanism, there is no device to realize the adjustment of the torsion bar torque. After the torsion bar turning mechanism is used for a long time, the torsion bar will inevitably experience torque attenuation due to fatigue. Torque attenuation causes too much operating force when turning over the cab, and even one person cannot complete the operation. At this time, it is necessary to replace the assembly or disassemble the torque arm, and reposition the pre-twist angle. This will inevitably cause maintenance difficulties, and also greatly increase the user's use cost. [0003] In order to adjust the torque of the torsion bar, the State Intellectual Property Office of China has published an ...

This will inevitably cause maintenance difficulties and greatly increase the user's use cost.

[0003] In order to adjust the torque of the torsion bar, the State Intellectual Property Office of China has published an invention patent of 2011110628457 titled Angle Adjustable Cab Double Torsion Bar Turnover System Assembly, which pushes the left adjusting bolt and / or the right adjusting bolt The turning arm and / or the right turning arm rotates, thereby adjusting the angle between the left turning arm and / or the right turning arm and the left torsion bar arm and / or the right torsion arm The rotation of the arm and / or the right turning arm can adjust the torsion angle of the upper torsion bar and / or the lower torsion bar, and finally achieve the purpose of adjusting the torsion force.
