Abstract

A hybrid vehicle has a first drive apparatus for driving wheels on a first axle by an internal combustion engine and a second electrical drive apparatus with two electrical machines for driving wheels on a second axle. At least one electrical energy store can be discharged when the two electrical machines are operated as a motor and can be charged when the electrical machines are operated as a generator. The two electrical machines of the electrical drive apparatus are combined with a respectively associated gearbox in an electrical axle to drive the individually suspended wheels on the first axle via universally jointed shafts. Two electrical converters are associated respectively with the two electrical machines and are combined in one converter unit, such that a basic module has the mechanical link to a bodywork structure, the link to a cooling circuit and the electrical link to an electrical energy store.
