Axle hybrid drive
First Claim
1. An axle hybrid drive for a hybrid vehicle comprising an internal combustion engine, drivingly connected to a first vehicle axle, and an electric motor, drivingly connected to a second vehicle axle, wherein the first vehicle axle includes a wheel, and wherein at least one of the internal combustion engine or a transmission allocated to the internal combustion engine are decoupled in terms of a driving force from the wheel and coupled in terms of a driving force to the wheel, wherein the decoupling occurs at the wheel,further comprising a freewheel arrangement, the at least one of the internal combustion engine or the transmission are decoupled via the freewheel arrangement from the wheel of the first vehicle axle, andthe freewheel arrangement includes a freewheel arranged between an end of a cardan shaft and a wheel bearing of the wheel of the first vehicle axle.
