Design of six speed transmission of 2019 model leading automobile of Geely Dihao<br>Abstract<br>The main requirement of automobile transmission is that it can cooperate with the engine well to ensure the reasonable power output of the engine, which requires that the transmission should have a reasonable number of gears and appropriate transmission ratio to match with the corresponding engine.<br>This design aims at the 2019 model of Geely Dihao leading automobile, changing the 5-speed manual transmission into 6-speed manual transmission and shift mechanism. Study the development trend of automobile transmission, and be familiar with the composition and requirements of transmission. Then according to the parameters of Geely Dihao 2019 model leading car, the maximum power, maximum torque, curb weight and other parameters of the engine, combined with the relevant knowledge learned, the distribution scheme of the transmission ratio and the corresponding gearshift mechanism form are proposed, and the scheme comparison is carried out, finally the appropriate scheme is selected, and the detailed design, calculation and verification as well as the input of the transmission are carried out , output shaft, driven gear, driving gear and reverse gear of each gear, select standard parts such as bearings, splines and bolts, and finally briefly describe synchronizer and control mechanism.<br>This design uses two axle six speed transmission, uses synchronizer to shift, the transmission ratio distribution is reasonable, the transmission efficiency is high, the power and the economy are good.<br>Key words: manual transmission; control mechanism; synchronizer; transmission ratio<br>
