Patent ID: 10738752

Abstract:
A drive train for a motor vehicle includes an internal combustion engine, a starting device, and a vibration isolation device. The internal combustion engine has a main order of vibration and an excitation frequency predetermined by a predetermined operating principle and a predetermined number of cylinders. The starting device is for starting the internal combustion engine and has an electric machine with a torque characteristic over a speed (n). The vibration isolation device is designed for the main order of vibration of the internal combustion engine. The vibration isolation device has a resonance characteristic below an idling speed (nL) of the internal combustion engine in a resonance range occurring in a first speed range (Δn2). The resonance range is shifted into a second, lower speed range (Δn1) when the electric machine is coupled. The electric machine is arranged to supply a torque effective beyond the second, lower speed range (Δn1).
