Abstract

The invention discloses a six-gear planetary gear automatic transmission. The six-gear planetary gear automatic transmission comprises a power input shaft and a power output shaft. The first output end of the power input shaft is connected with a front-row gear ring of a planetary gear mechanism through a first clutch, the second output end of the power input shaft is connected with a front-row sun gear of the planetary gear mechanism through a second clutch, the third output end of the power input shaft is connected with a rear-row gear ring of the planetary gear mechanism through a third clutch, the fourth output end of the power input shaft is connected with a rear-row planetary frame of the planetary gear mechanism through a fourth clutch, and the fifth output end of the power input shaft is connected with a rear-row sun gear of the planetary gear mechanism through a fifth clutch. The automatic transmission is composed of double row planetary gear mechanisms with different parameters, the double row planetary gear mechanisms are relatively independent, and six gears with reasonably-distributed transmission ratios can be formed; and when all the gears work, power is transmitted by a single row planetary gear mechanism, a power transmission line is simple.

Description

technical field [0001] The invention relates to a six-speed planetary gear automatic transmission. Background technique [0002] An automatic transmission generally includes frictional engagement elements such as planetary gear units, clutches, and brakes. The automatic transmission uses automatic transmission oil for energy conversion and power transmission, and uses oil pumps, oil circuits, clutches, planetary gear sets, multiple solenoid valves and other components to realize automatic transmission, bringing easy and simple driving experience to people's car driving . [0003] The existing automatic transmission is mainly composed of a Lavina type planetary gear structure or a Simpson gear structure, and is a 4-speed transmission. The characteristics of the Lavina planetary gear structure: it is a double-row structure, and the front and rear rows share a ring gear and a planetary carrier; on the planetary carrier, the outer planetary gear is a long planetary gear, meshi...
