Routing auxiliary attachment for e.g. caravan trailer, has hub motors switched by controller between engine operation in which motors exert driving power on trailer wheels and generator operation in which motors produce electrical energy

摘要

The attachment has electric motors connected with vehicle wheels and energized by a battery. The motors are designed as hub motors or generators (8) and an electrical controller (9) is connected with hub motors. The hub motors are switched by the controller between an engine operation in which the motors exert driving power on trailer wheels and a generator operation in which the motors produce electrical energy.
