According to the design requirement to choose a three-axis 4th speed transmission and the fixed middle shaft, the reverse stall used to shift the gear on the reverse gear shaft, the other stalls used Synchronizer shift, according to the design requirements of the light truck,the manipulation agencies use remote control. Noted and demonstrated that the transmission parameters, the calculations and the list of gear geometry parameters,the gear material selection,gear strength and strength check, the design of the shaft and stiffness and strength check,shaft material selection, bearing selection,spline options and check.And briefly introduce the transmission disassembly sequence, as well as a summary of this design.The whole graduation design lasts three months, and it is completed under the teacher's leading and the help of the classmate smoothly. Finally thanks to the teachers and classmates who give me much help during the graduation design. This design, includes 1 No.0 diagram papers and 2 copies of three-dimensional graph by computer and manual drawing, translating a foreign information, preparing four MATLAB Programming Language, and edit a manual.
