Cab sealing structure design ideas. Design Objective: To improve the living environment of the cab body; improve corrosion candle body requirements. The main design elements: the sealing design prevents rain (water), dust, pollution gas invasion cab; prevent vibration, noise, heat sealing invasion cab design; prevent corrosion media intrusion candle body panel seal design. Category: requirements and seal tightness in accordance with structural features can be divided into static sealing sealing design and dynamic sealing two categories. When heavy truck HOWO standard cab cab windows always become locked state, that is when the cab tilting angle of 0 °. In this case, the maximum torsion angle of the torsion bar, the torsion bar of the maximum torque, the maximum torque of the cab of heavy long cab, but the torsion bar of the torque is greater than the weight of the cab moment; when releasing the locked state, since the torsion bar torque is greater than the cab heavy torque, the torque effect of the torsion bar in the cab automatically flips forward to after a static point of view, shown in Figure 2-2, this time the cab flip angle α is small, the torsion bar of torque cab equal weight moment; when the smaller man exerts an upward thrust in the locking position of the cab structure, the cab started to roll forward, slowly release the energy of the torsion bar, heavy torque cab decreasing, flip speed gradually slowed down; when the rollover to the maximum position, that the center of gravity of the cab slightly more than flip vertical center cab shell, then re-torque is almost zero, then gently push the cab, will rely limit cab fixed residual torque of the torsion bar to make the stopper in tension.
