Abstract

The invention relates to an automatic mechanical transmission based on a multi-piece electromagnetic clutch, which belongs to the technical field of automobile manufacturing. A first-gear driven gear and a second-gear driven gear in a transmission are arranged on an output shaft, the first-gear driven gear is meshed with a first-gear driving gear, and the second-gear driven gear is meshed with a second-gear driving gear. The first-gear driving gear, a first-gear flange sleeve, a multi-piece electromagnetic double-clutch and a second-gear flange sleeve are disposed sequentially and coaxially on an input shaft. The automatic mechanical transmission based on the multi-piece electromagnetic clutch has the advantages that since structure is compact, chassis arrangement space can be saved; automatic gear-shifting can be realized, and shifting operation is simple; power is not interrupted and no impact is produced when shifting gears, and comfort of riding is guaranteed.

Description

technical field [0001] The invention relates to an automatic mechanical transmission based on a multi-plate electromagnetic clutch, which belongs to the technical field of automobile manufacturing. Background technique [0002] With the increasing requirements for the economy and emission of automobiles, various new energy vehicles have emerged. Among them, small pure electric vehicles, as an important member of the electric vehicle family, are receiving more and more attention. Most of the existing small pure electric vehicles are directly driven by the motor without a transmission, and the power is directly transmitted to the drive shaft through a one-stage deceleration. Such a small pure electric vehicle cannot achieve deceleration and torque increase when starting and climbing, and the power is insufficient. If the slope is too long, the peak power of the motor may be burned if the motor is continuously used; if the first-stage reduction ratio is increased, the torque wi...
