Abstract
A coupling device and a coupling mechanism is provided for selectively coupling of an electric drive to a wheel axle of a vehicle. The coupling device includes, but is not limited to an output gear connected to the wheel axle, an input gear connected to the electric motor. A synchronizer is adapted to contactlessly minimize a difference of the input gear's and the output gear's angular velocity below a predefined threshold, and a synchronizing member is adapted to frictionally engage with the input gear and/or with the output gear when the difference in angular velocity of input gear and output gear is below the predefined threshold.
