When heavy truck HOWO standard cab 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's weight, 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 is greater than the driving torque Room heavy torque, the torque in the torsion bar effect, the cab automatically flips forward to an angle later still, shown in Figure 2-2, then flip angle α smaller cab, and the cab of the torsion bar of torque equal weight moment; when the smaller man exerts an upward thrust in the locking position of the cab structure of Shandong, Shaanxi Automobile Delong cab Suppliers, cab started to roll forward, Shandong and Shaanxi Automobile Delong cab Suppliers, torsion bars slow energy release, the cab heavy torque decreasing Shandong, Shaanxi Automobile Delong cab suppliers flip rate gradually slowed down; when the rollover to the maximum position in Shandong and Shaanxi Automobile Delong cab supplier, namely the cab of the center of gravity slightly more than the central vertical flip, then re-torque is 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. Shaanxi Automobile Delong cab and cab trucks and other heavy rain test body rain tightness test role: Body rain test is an important means to test and determine the body sealing performance, the current heavy truck manufacturers mostly through body rain test to verify sealing performance car products. Rain test vehicle practice: 1, the test subject test object Shaanxi Automobile Factory Shaanqi cab, Delong cab car products. Above models in interior and chassis assembly after completion by the debugger to debug products Car drivers will line up in order to enter the rain room test. 2, number of tests. Shaanqi factory quality management department under the cab of the above three types of tests to be 100%. Automobile plant is based on the size of their production volume to develop their own rain test number, the test aims to identify problems and timely improvement failed project, so that customer satisfaction is maximized.
