Artificially self-controlled synchronous exchange two-gear variable speed electric drive system

Abstract

The utility model discloses a kind of human self-control synchronous exchange two-gear variable-speed electric drive system, by additionally setting overrunning clutch and additionally setting first synchronizing ring on high speed gear combination gear and additionally setting second synchronizing ring on low speed gear combination gear, whether it is low speed gear switching for high speed gear, or high speed gear switching for low speed gear, gear sleeve will first pass through synchronous exchange position, make gear sleeve simultaneously drive first synchronizing ring and second synchronizing ring with its synchronous rotation, then again with high speed gear combination gear or low speed gear combination gear combination, to not only can realize easy reverse gear and in gear, and greatly reduce gear impact and abrasion problem caused thereby, reduce maintenance cost and maintenance frequency, simultaneously also greatly optimize gear dullness, improve driving experience and comfort, and, by setting special high speed gear moving route separation mechanism, avoid the efficiency loss of existing tricycle manual transmission.
