the speed automatically according to the road conditions, it has made great drivers.Not only can alleviate drivers driving fatigue reduce road traffic accidents, but also can improve the fuel economy of the car.At the same time, it can improve power performance of car.Planetary gear transmission main structure for a planet gear mechanism, the planetary gear mechanism is mainly composed of the sun wheel, outer ring gear, planetary wheel, planet carrier.Because the planet gear mechanism has two degrees of freedom, so the planet gear mechanism has no fixed transmission ratio, cannot be directly applied to the transmission.In order to be able to will be applied in the automatic transmission planetary gear transmission, the gear mechanism of components must be fixed exhibit a degree of freedom.There is only one degree of freedom of planet gear mechanism has a fixed ratio, thus can be used in the automatic transmission.I design for commercial vehicles planetary gear transmission, the planet gear mechanism has the advantages of compact structure, large rigidity, smooth transmission.Planetary gear transmission power changes controlled by hydraulic torque converter, its operating mechanism for the clutch and brake, and the control with the hydraulic oil, so as to realize automatic shift.However, the automatic transmission structure is more complex.Through this graduation design I made a lot of work on automatic transmission principle and refer to commercial vehicles models ultimately determine the transmission scheme, and has made the detailed instructions for each transmission ratio.&nbsp;</p><p>KeyWords:automatic transmisson &nbsp;lanetary gearbox &nbsp;torque converter &nbsp;</p><p>目 &nbsp;錄</p><p>摘要<span class="Apple-tab-span"
