When heavy truck HOWO standard cab always become locked state, that is when the cab tilting angle of 0 °. At this point, Hainan, Shaanxi Automobile Delong cab offer, the twist angle of the torsion bar is maximum, maximum torque of the torsion bar, the maximum torque of the cab's weight, but the torsion bar of the torque is greater than the weight of the cab moment; when the lock condition is removed Since the torsion bar of the 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, Hainan, Shaanxi Automobile Delong cab quotes as shown in Figure 2-2, this time Cab tilting angle α smaller torsion torque moment equal weight with cab; when the person applying smaller upward thrust locking mechanism position in the cab, the cab started to roll forward, Hainan, Shaanxi Automobile Delong driving room quotes, slow release of energy of the torsion bar, heavy torque decreasing cab, flipped rate gradually slowed down; when the rollover to the maximum position, which is slightly more than the center of gravity of the cab central vertical flip, then re-torque almost zero, then gently push the cab, the cab rely stopper fixed residual torque of the torsion bar so that the stopper is in tension. Improving driver comfort, thereby reducing operator fatigue, Shaanxi Auto setting cab driver can not only guarantee good health, but also to ensure road safety significance 'in recent years as materials technology and manufacturing technology continues Hainan progress Shaanxi Automobile Delong cab offer, air suspension being developed using people's attention. Research by computer simulation using the soft air suspension in the cab suspension to improve ride comfort results from the elastic vibration theory of general beam cross - Export bending vibration differential equations motion, then each particle and rigid body () vibration synthesis, thereby establishing heavy vehicle vibration model includes elastic vibration of the frame 'This model of heavy-duty vehicle ride comfort by computer simulation, verification cab air suspension can greatly improve the ride comfort was evaluated to improve effect. To improve the cab comfort Shaanxi Auto, suspension system parameters must be adjusted taking into account the car's suspension between the frame and the wheels have been using air suspension 'to stabilize the posture of the body is not appropriate to reduce the stiffness' so consider Deals small cab suspension stiffness to improve comfort! But lower suspension stiffness dynamic deflection to increase significantly 'to break the routine for this article' over-damped with large damping relative damping front and rear cab suspension is greater than. Cab offset frequency in between! S is the vertical acceleration power map cab air suspension driver's seat when the spectral density curve simulation results. Improved driver's seat vertical acceleration power spectrum random response curve.
