Abstract

The invention provides a six-gear planetary automatic transmission which comprises planet rows, transmission components, brakes, clutches, an input component and an output component, wherein the input component and the output component are connected with an input shaft and an output shaft respectively. The first planet row is connected with the input component, the first transmission component and the second transmission component; the second planet row is connected with the second transmission component, the first transmission component and the third transmission component; the third planet row is connected with the fourth transmission component, the first transmission component and the output component; the fourth planet row is connected with the third transmission component, the output component and the fifth transmission component; the fifth planet row is connected with the sixth transmission component, the output component and the fifth transmission component; the first brake, the second brake, the third brake and the fourth brake are used for braking the first transmission component, the second transmission component, the fifth transmission component and the sixth transmission component respectively; the first clutch is connected with the input component and the fourth transmission component, and the second clutch is connected with the input component and the first transmission component. Compared with the prior art, the six-gear planetary automatic transmission is provided with six forward gears, is wide in transmission ratio range, facilitates realization of a straight-gear planet row structure and is compact in structure, and the size and the weight of the transmission are reduced.

Description

technical field [0001] The invention relates to a transmission, in particular to a six-speed planetary automatic transmission. Background technique [0002] Automobile transmission is a set of transmission devices used to coordinate the engine speed and the actual driving speed of the wheels, and is used to exert the best performance of the engine. The transmission can generate different gear ratios between the engine and the wheels during the running of the car, and the engine can work at its best power performance state through gear shifting. The development trend of the transmission is more and more complicated, and the degree of automation is getting higher and higher, and the automatic transmission will be the mainstream in the future. [0003] The speed change mechanism of the automatic transmission changes the speed and torque output by the hydraulic torque converter, and outputs the changed speed and torque through the output shaft to meet actual needs. As we all k...
