Abstract

A motor vehicle includes two vehicle wheels, which are arranged on a common vehicle axis, and two single wheel suspension devices of an active chassis, via which the vehicle wheels are each connected to an engine vehicle body. The single wheel suspension devices each have a shock damper, which can be fluidically connected to an engine pump unit to vary the damping behavior. The engine pump unit is arranged in the area of the common vehicle axis. The engine pump unit and a further device arranged in the area of the vehicle axis are arranged off-center in the vehicle transverse direction. The engine pump unit is arranged spaced apart from the further device in the vehicle transverse direction.

First claim

What is claimed is:

1 . A motor vehicle comprising:
two vehicle wheels arranged on a common vehicle axis; and two single wheel suspension devices of an active chassis, via which the vehicle wheels are each connected to a vehicle body, wherein the single wheel suspension devices each have a shock damper, which is configured to be fluidically connected to an engine pump unit to vary the damping behavior, wherein the engine pump unit is arranged beside the common vehicle axis, wherein the engine pump unit and a further device arranged beside the vehicle axis are arranged off-center in a vehicle transverse direction, and wherein the engine pump unit is spaced apart from the further device in the vehicle transverse direction.

2 . The motor vehicle according to claim 1 , wherein the engine pump unit and the further device are arranged off-center in the vehicle transverse direction, such that a center of mass is arranged centrally in the vehicle transverse direction.

3 . The motor vehicle according to claim 1 , wherein the engine pump unit and the further device are arranged in the vehicle vertical direction flush to each other.

4 . The motor vehicle according to claim 1 , wherein the engine pump unit and the device are arranged spaced apart from each other in the vehicle longitudinal direction.

5 . The motor vehicle according to claim 1 , wherein the further device is a steering assist device.

6 . The motor vehicle according to claim 1 , wherein each shock damper is fluidically connected to the engine pump unit.

7 . The motor vehicle according to claim 1 , wherein said further device is an electric steering assistance unit.

8 . The motor vehicle according to claim 7 , wherein the pump unit and the electric steering assistance unit are positioned on different sides of a vehicle longitudinal axis that is defined along a travel axis of the vehicle.

9 . The motor vehicle according to claim 7 , wherein the electric steering assistance unit comprises a control unit and a steering assistance unit that is electrically connected with the control unit, wherein the steering assistance unit is operatively connected to a rack of a steering system of the motor vehicle.

10 . The motor vehicle according to claim 9 , wherein the rack includes a toothing and a gear wheel having a mating toothing that is mated with the toothing of the rack, and wherein the gear wheel is connected to a steering wheel of the vehicle via a steering shaft such that rotation of the steering wheel causes rotation of the gear wheel which causes translation of the rack which causes a steering movement of the motor vehicle.

11 . The motor vehicle according to claim 9 , wherein the pump unit is positioned at an elevation above the rack and the steering assistance unit is positioned on the rack.

12 . The motor vehicle according to claim 11 , wherein the pump unit and the steering assistance unit are positioned on different sides of a vehicle longitudinal axis that is defined along a travel axis of the vehicle.
