According to the patent summary information of Tianyancha, this application embodiment provides a reducer, powertrain and vehicle, and the reducer can be applied For electric vehicles/electric vehicles, pure electric vehicles, hybrid vehicles, extended range electric vehicles, plug-in hybrid vehicles, new Energy vehicles, etc., by canceling the setting of the synchronization ring, using the control of the rotation angle and speed, the reducer realizes the shift without power shock, shortens the shift stroke and synchronization time, saves costs, and solves the problem of using the synchronization ring to achieve friction. Synchronous shifting causes long shifting time and impacts during shifting.
