Abstract

An automatic transmission comprises a transmission case, a transmission input shaft, a transmission output shaft, a speed-change mechanism arranged between the transmission input shaft and the transmission output shaft and comprising a plurality of rotating elements, and an advancing and reversing gear shifting mechanism arranged in the transmission. Multiple outputs of different speed ratios canbe generated by multiple torque transmission mechanisms, which can selectively enable a speed-change mechanism input end gear and a speed-change mechanism output end gear of the speed-change mechanismto be connected or separated between the transmission input shaft and the transmission output shaft based on speed-change instructions, to meet vehicle driving requirements. The automatic transmission has the beneficial effects that the main speed-change transmission part of the transmission is the gear speed-change mechanism on the end face of an ordinary gear train, so that the structure is simple, control is easy, and the defect of complex structure and difficult design, manufacturing, gear-shifting control and maintenance of a traditional transmission are overcome.

Description

[0001] Technical field [0002] The invention relates to an automatic transmission, which belongs to the technical field of mechanical transmission, and in particular to an automatic transmission comprising a plurality of gear transmission mechanisms and a plurality of torque transmission mechanisms, and having a plurality of shift gears. Background technique [0003] Considering factors such as fuel economy and shift smoothness, automatic transmissions are required to realize multi-speed shifting. In the technical scheme that has been proposed, the automatic transmission that obtains a plurality of transmission ratios is obtained by torque transmission mechanism, planetary gear unit coupling combination. However, in order to constitute the above-mentioned automatic transmission that can realize multi-speed shifting, it is necessary to design complex power connection transmission paths between multiple torque transmission mechanisms and the rotation units of multiple planetary...
