Electrical gear of modular drive for road vehicle, for almost loss-free stepped switching of driving motor power and rpm; has combination of simple and robust mechanical and electrical components

摘要

The gear has a combination of simple and robust mechanical and electrical components. The gear has electric switch gear and no rotating parts. The electric switching of gears, accumulators and generators, and the driving motor may be connected in series or in parallel, so that the driving motors, and their power and rpm, are controlled by voltage and current. The accumulators, generators and driving motors are not short-circuited.
