Embodiment Construction

[0039] specific implementation plan

[0040] The shown variant is used in particular in vehicles with all-wheel drive. The second axle, not shown, is preferably driven by means of an internal combustion engine, according to Figure 2.1 to Figure 2.8 as well as Figure 4.1 to Figure 4.12 In these concepts, the internal combustion engine is used to additionally drive a further axle which can be driven by an electric machine.

[0041] 1. Electric machines arranged longitudinally without mechanical all-wheel drive

[0042] Figure 1.1 and Figure 1.2 shows an axle concept with two electric machines, and Figure 1.3 and Figure 1.4 An axle concept with one electric machine is shown.

[0043] Figure 1.1 A plan view of an axle of a passenger vehicle, specifically a front axle 1 of the passenger vehicle, is shown. This axle 1 has two wheels 2 . In plan view, the arrangement is shown in such a way that the direction of travel of the vehicle is from right to left, relative to ...

Abstract

The invention relates to a vehicle having an electric drive. The vehicle has a front and rear axles and at least one drive that comprises an electric machine for driving at least one wheel of one of the axles.

Description

technical field [0001] The invention relates to a vehicle with an electric drive. Background technique [0002] Vehicles, especially passenger vehicles, can be driven exclusively electrically by means of an electric machine. The vehicle can also be used as a hybrid vehicle equipped with an electric machine and an additional, non-electric drive, in particular an internal combustion engine. The internal combustion engine can either only charge an energy store (in particular an electric energy store, such as the vehicle battery (series hybrid)), or be mechanically coupled to a drive shaft (parallel hybrid), or both Both. In order to be able to reduce the fuel or energy consumption of a hybrid vehicle, the electric machine is used as a generator during braking of the vehicle and in this way charges an energy store. The electric machine thus acts as an electric brake and regenerates energy. In addition to or instead of this, there is at least one additional operating state of...
