Abstract
This design requires access edge with transmission DF6S850 of EQ1181 Truck matching, Request: the maximum output torque transmission 850Nm,get maximum output torque of Power 450Nm; to meet the strength and stiffness requirements; high transmission efficiency; good processing process and assembly process of. The devices take power from the power form of power transmission from the left side of cover, and the overall structure of the form of a two-axis, taking power from the device to a dedicated power transfer between the devices can be used mechanical transmission. First of all, the EQ1181-type vehicle in accordance with engine and transmission parameters and a dedicated device used to determine the parameters of Power from the transmission ratio, determined in accordance with the assembly of space inside edge from the center distance of two gear range, under the power transmission gear parameters taken from the two gear power devices module, pressure angle, tooth width and other parameters. After the shaft, gear and keys to check to verify the reliability of ponents. Then, check plete device assembly drawing ponents drawing. Finally, the preparation of parts of the processing process.
Analysis by calculating the force from a reasonable structure design, manufacturing process is simple, the basic can be used in actual production and use, meet the design requirements.
Key words:truck;transmission; power take off; design;technology.
