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 torque maximum, Shaanxi Auto cab, the cab of heavy torque maximum, but the torsion bar of the torque is greater than the weight of the cab moment; when releasing the locked state, due twisting The torque rod is greater than the cab heavy moment, Beijing cab, at the torque effect of the torsion bar, the cab automatically flips forward to an angle later still, shown in Figure 2-2, then flip angle α smaller cab torsion bar 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, slowly release the energy of the torsion bar, heavy cab moment decreasing, flip the speed gradually slowed down; when the rollover to the maximum position, Oron cab, the cab's center of gravity slightly over the center vertical flip, then re-torque is almost zero, then gently push cab, cab rely stopper fixed residual torque of the torsion bar so that the stopper is in tension. Delong cab injector seal due to poor fuel leak if you can not make the time to spray atomization and positive, even because Delong cab injector seal due to poor fuel leakage, it will make fuel gathered in certain parts of the continuous combustion cylinder. Because of this combustion engine always runs through the whole process (intake, compression, do, row). Thus, it will cause excessive temperatures generated within the cylinder, which burned parts. The present case the car when the engine overhaul, no injector is corrected, there is no maintenance of the fuel system (only at the top before melting occurs on the fuel injector correction). Therefore, a comprehensive analysis, we can conclude that the fuel system is not working properly Delong cab caused by the melting of the piston top. From the above case, we can get a lot of inspiration, the repair shop, the cab price, not only in the maintenance of a comprehensive, detailed, and more important to repair before (or at the time of the vehicle into the plant) for all to be repaired The scope and content owners Delong cab necessary clear, otherwise, it is prone to conflicts. This is particularly important for some small repair business. Cab _ do Yiu Cheung Trading (certified) _ Beijing cab provided by Jinan Yiu Cheung Trading Company.
