Problems solved by technology

Among them, when a hydraulic torque converter is used to transmit power, a hydraulic device needs to be added, which has a complex structure and low mechanical efficiency; when a traditional magnetic powder clutch is used to transmit power, the electromagnetic field generated by the yoke coil makes the magnetic powder magnetized to transmit power, and there are Speed ​​slip, low transmission efficiency, and short service life; when the friction plate clutch is used to transmit power, the engagement or separation of the friction plate clutch is controlled by a hydraulic actuator, a pneumatic actuator, or an electric actuator, and the structure of the control actuator is complex

Abstract

The invention discloses a locking magnetic powder clutch type automatic gearbox. According to the locking magnetic powder clutch type automatic gearbox, a first electric stud valve and a second electric stud valve of a locking magnetic powder clutch are added, and the two electric stud valves of the locking magnetic powder clutch are controlled to be powered on and powered off, so that mechanical locking transmission and separation of the locking magnetic powder clutch are achieved. The locking magnetic powder clutch type automatic gearbox has the beneficial effects of being high in transmission efficiency, long in service life and the like.

Description

technical field [0001] The invention relates to an automatic transmission, more precisely a lock-up magnetic powder clutch type 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 present, a hydraulic torque converter or a traditional magnetic powder clutch is usually used to transmit the power of a power device such as an engine or an electric motor to a hydromechanical automatic transmission (AT), a metal belt continuously variable automatic transmission (CVT), a dual-clutch automatic transmission, etc. A transmission (DCT), an automatic mechanical transmission (AMT), or a friction plate clu...
