Abstract

The invention relates to an automatic speed-changing mechanism for an electric vehicle, which comprises an input shaft (1), and a first gear (5) and a second gear (6) which are fixed on the input shaft (1). The automatic speed-changing mechanism also comprises a transmission shaft (11), and a third gear (7), a fourth gear (8) and a fifth gear (9) which are fixed on the transmission shaft (11); the third gear (7) is positioned between the fourth gear (8) and the fifth gear (9); the upper end between the input shaft (1) and the transmission shaft (11) is provided with an electric push-and-pull controller (2); a shifting fork (3) is arranged on a shaft of the electric push-and-pull controller (2); the shifting fork (3) is sheathed on the input shaft (1); and a sensing plug (4) is arranged besides a sixth gear (10). By adopting two gears including a top gear and a bottom gear, compared with the existing automatic speed-changing mechanism, the automatic speed-changing mechanism for the electric vehicle is greatly changed, the top gear and the bottom gear can be automatically converted with each other, and the operation is simpler and more humanized.

Description

technical field [0001] The invention relates to an automatic transmission mechanism of an electric vehicle. Background technique [0002] With the rapid development of vehicle control automation, the automatic transmission mechanism of automobiles is showing a trend of vigorous development. The existing automatic transmission mechanisms mainly include mechanical automatic transmissions, mechanical continuously variable transmissions, and electronically controlled mechanical transmissions that are being studied at home and abroad in recent years. Automatic transmissions, etc. The development of electronically controlled mechanical automatic transmissions has attracted the attention of major automobile factories because of its advantages of high fuel economy, low emissions and protection of existing manual transmissions required by the development of the automobile industry. However, the existing electronically controlled mechanical automatic transmission has the problem of po...
