Patent ID: 6954003

Claim:
A mobile, self-sufficient operating assembly for providing electrical energy, comprising; two internal-combustion engines and two generators wherein the internal-combustion engines and the generators are mutually connected by way of a transmission gearing comprising several shifting clutches, and electrical control devices for controlling the several shifting clutches of the transmission gearing wherein is a first condition each of the two internal-combustion engines drive a respective one of said two generators, in a second condition both internal-combustion engines together drive each of the two generators and, in a third condition one of said internal combustion engines drive both generators together, wherein the transmission gearing comprises two essentially identically constructed partial gearings, one partial gearing comprising an engine-side shifting clutch and a generator-side shifting clutch. which are arranged in line with respect to one of said two internal-combustion engines and one of said two generators respectively, wherein the two partial gearings are capable of being coupled by way of a belt drive at an output side of the two engine-side shifting clutches.
