Abstract

The invention discloses an automatic two-stage drive-by-wire multiple-gear transmission. A primary inner gear ring is constantly meshed with a first high-speed gear and a second high-speed gear along the peripheral inner sides of the gears. A secondary fly wheel inner gear ring is constantly meshed with a third high-speed gear, a fourth high-speed gear, a fifth high-speed gear and a sixth high-speed gear along the peripheral inner sides of the gears. A secondary fly wheel central gear is constantly meshed with a seventh high-speed gear. The high-speed gears are respectively connected with the driven ends of electromagnetic clutches, and the driving ends of the electromagnetic clutches are respectively connected with driving gears. The driving gears are respectively meshed with driven gears. Separation and connection of the electromagnetic clutches are respectively controlled by an electrical control unit, and drive control of forward gears and reverse gears is achieved. The automatic two-stage drive-by-wire multiple-gear transmission has multiple gears, is compact in structure and free of mechanical or hydraulic gear-shifting parts and adopts drive-by-wire power gear shifting.

Description

technical field [0001] The invention relates to an automatic transmission, more precisely a two-stage wire-controlled multi-speed 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 transmiss...
