ABSTRACT
This paper EQ1168 back east, overall layout design tank reservoir of the transport research material tank car, according to this topic title selection EQ1168kJ2 heavy truck dongfeng company on its site, and the overall design and jacket vehicle design.
This paper EQ1168 back tanker chassis major parts and parameters (including size parameters and performance parameter selection and calculation), completed the overall layout design. In this section, the first on the automobile chassis layout forms of choice, then, according to certain chassis layout forms, consider mainly size parameters and performance car the parameter selection and calculation, and on this basis to determine the hydraulic system and flip institutions components.
Refer to state standard according to the economy and reliability back tanker, determined the jacket structure, and according to the motion scheme, kinematic scheme, hydraulic system design for flip institutions designed to make the maximum pressure hydraulic system, at the same time to consider the smallest components of technology.
