Abstract

The invention discloses a lockable magnetic powder clutch type automatic six-gear gearbox which comprises a lockable magnetic powder clutch and electric stud type joint devices of all gears. The lockable magnetic powder clutch and the electric stud type joint devices of all gears are controlled to be powered on and powered off, and thus gear shift control over all the gears is achieved. The lockable magnetic powder clutch type automatic six-gear gearbox has the beneficial effects of being high in transmission efficiency, compact in structure, capable of achieving dynamic power shift, free of mechanical or hydraulic gear shift components and the like.

Description

technical field [0001] The invention relates to an automatic transmission, more precisely a six-speed automatic transmission of a lockable magnetic powder clutch type. 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 at present. 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...
