Abstract
The topic of this project is a design of transmissions for a medium-size truck. The adoption of suitable designs and layout enables the effective utilization of engine to improve the truck's motility and economy. The design was referred to parameters of Beijing Foton truck and relevant books. Via a comprehensive demonstration, the data was collected from various components of the transmission which were modeled by Solidworks. The transmission is a five-speed transmission, including five forward gears and one reverse gear, applying advanced monolithic structure of the intermediate shaft and the shift lock ring-type synchronizer. The gearbox possesses a compact structure, a small size, high transmission efficiency, and a larger ratio range, with good economy and dynamic performance. [资料来源：https://www.doc163.com]
