Abstract

An alternating shift type dual-motor automatic transmission belongs to the field of electric vehicles. Connected with a controller, two motors are used to drive an alternating gear shift gearbox to gradually shift gears and change the speed of the electric vehicle. By using this automatic shift transmission, the speed can be changed without being able to be controlled by the controller 14, and The speed change can be performed by using a mechanical transmission. This double-motor automatic transmission has small starting current, stable gear shifting, and simple structure, which is conducive to mass production.

Description

technical field [0001] The invention relates to a gearbox, in particular to an alternate gear shifting type automatic gearbox with two motors, which belongs to the field of electric vehicles. Background technique [0002] As an environmentally friendly and non-polluting electric vehicle, it is currently in the transition period from the primary stage to the high-level field. With the advancement of technology, it is constantly developing to new heights. Among them, the control system of electric vehicles is also constantly improving with the advancement of technology, and its functions are constantly improving. The pace of upgrading is accelerating, and it is constantly catching up with the mechanical structure of vehicles. pace. [0003] In the mechanical structure, gear shifting is a method of connecting two clutches with a gearbox, and then connecting with the engine to perform alternate gear shifting. However, in electric vehicles, only the control system of the electri...
