Abstract

The invention discloses a drive-by-wire automatic transmission with multiple gears annularly arranged. A high-speed gear of each advancing gear is constantly engaged with a flywheel inside engaged gear. A high-speed gear of a back gear is constantly engaged with a central outside engaged gear. A driving gear and a driven gear of each gear are constantly engaged with each other. A first-gear main shaft, a second-gear main shaft, a third-gear main shaft, a fourth-gear main shaft and a back-gear main shaft are annularly arranged on the periphery of an intermediate shaft of the transmission. Engagement and disengagement of an electromagnetic clutch of each gear are controlled by an electronic control unit, so that power transmission of each gear is achieved. Power gear shifting is achieved in a drive-by-wire mode. The drive-by-wire automatic transmission with the multiple gears annularly arranged has the advantages that the structure is compact, drive-by-wire power gear shifting is adopted, and mechanical or hydraulic gear shifting components are omitted.

Description

technical field [0001] The invention relates to an automatic transmission, more precisely, a multi-speed ring-arranged wire-controlled automatic transmission. Background technique [0002] Automatic transmissions are widely used in various vehicles such as automobiles, electric vehicles, and construction machinery. The existing automatic transmissions mainly include hydromechanical automatic transmission (AT), metal belt continuously variable automatic transmission (CVT), mechanical automatic transmission (AMT) and dual clutch automatic transmission (DCT). [0003] AT is mainly composed of hydraulic torque converter, planetary gear and hydraulic control device. It is an automatic transmission widely used at home and abroad. It can automatically adapt to changes in driving resistance. The power is not interrupted during the shifting process, and it is more stable when starting and accelerating. But at the same time, there are disadvantages such as complex structure, low tran...
