Abstract

The invention discloses an automatic transmission which comprises a tap position gear transmission system, a gear-shifting mechanism execution system and a power connecting system, wherein the gear-shifting mechanism execution system comprises a control device, a reverse movement device and a gear-shifting switching device; the automatic transmission is characterized in that the tap position gear transmission system is double-shaft second-gear gear transmission or epicyclic gear train gear transmission; the power connecting system surpasses a reverse gear coupling or a conical surface buffer coupling or surpasses a reverse gear buffer coupling or a conical surface ring buffer device; the reverse movement device is a linkage internal reverse device or an integrated internal reverse device or an integrated linkage internal reverse device; and the gear-shifting switching device realizes gear switching to change speed through the following manner: a driven rack is arranged on a gear shaft in a sleeving manner, a sliding sleeve of the driven rack is assembled with a crank throw of a guide rod, the guide rod is assembled with a moving combination body, and the moving combination body is combined with or separated from a rotary combination body. The automatic transmission is high in transmission efficiency, long in service life and used for an electrombile to save electric energy.

Description

technical field [0001] The invention relates to an automatic transmission for shifting gears in the transmission of an electric vehicle, in particular to a fully automatic gear-shifting device for a driving wheel hub of an electric vehicle, a drive axle differential motor and a second-speed variable motor, which belongs to the technical field of mechanical transmission. Background technique [0002] Some of the drive hubs of existing electric vehicles realize electronic shifting or manual shifting, which is expensive and inconvenient to use; the manual shifting operation of the differential motor of the drive axle of the existing electric vehicle is cumbersome, which affects driving safety and has low transmission efficiency; Motor-type automatic shifting is expensive, unstable in performance, and not convenient enough to use. [0003] In the prior art, the automatic transmission disclosed in the Chinese invention patent application (application number: 201210125541.8) inclu...
