Abstract

A vehicle has a body, a flat component arranged under the body, and at least one axle carrier arrangement for two front or two rear wheel suspensions. The axle carrier arrangement includes a left-hand suspension arm bracket for connecting at least one suspension arm of the left-hand wheel suspension, a right-hand suspension arm bracket for connecting at least one suspension arm of the right-hand wheel suspension, and a center suspension arm bracket for connecting at least one suspension arm of the lefthand wheel suspension and at least one suspension arm of the right-hand wheel suspension. The three suspension arm brackets are each mounted on the body and the flat component, wherein the three suspension arm brackets are three separate components that are not directly connected, and wherein at least one of the suspension arm brackets has a bearing for an electric machine that drives the vehicle.

First claim

What is claimed is:

1. A vehicle, comprising:
a body;
a flat component mounted underneath the body; and
at least one axle carrier arrangement for two front or two rear wheel suspensions, the axle carrier arrangement comprising three suspension arm brackets which are:
a left-hand suspension arm bracket for attaching at least one suspension arm of a left-hand wheel suspension,
a right-hand suspension arm bracket for attaching at least one suspension arm of a right-hand wheel suspension, and
a center suspension arm bracket for attaching at least one suspension arm of the left-hand wheel suspension and at least one suspension arm of the right-hand wheel suspension,

wherein the three suspension arm brackets are each fastened on the body and on the flat component,
wherein the three suspension arm brackets are three separate component parts not connected directly, and
wherein at least one of three suspension arm brackets comprises a bearing for an electric machine driving the vehicle.

2. The vehicle according to claim 1 , wherein all three suspension arm brackets comprise a bearing for the electric machine driving the vehicle.

3. The vehicle according to claim 1 , wherein at least one of the three suspension arm brackets is connected to the body rigidly.

4. The vehicle according to claim 3 , wherein at least one of the suspension arm brackets is connected to the flat component rigidly.

5. The vehicle according to claim 4 , wherein the flat component is connected in a non-destructive releasable manner to all three suspension arm brackets.

6. The vehicle according to claim 5 , wherein the body is connected in a non-destructive releasable manner to all three suspension arm brackets.

7. The vehicle according to claim 6 , wherein the flat component is connected in a non-destructive releasable manner to the body at at least one body attachment point.

8. The vehicle according to claim 7 , wherein the flat component is formed as a structural reinforcement so that the axle carrier arrangement is only load-bearing by fixing the three suspension arm brackets on the flat component and on the body.

9. The vehicle according to claim 4 , wherein the at least one suspension arm bracket connected to the body rigidly and the at least one suspension arm bracket connected to the flat component rigidly have a screw connection without any elastic bearing.

10. The vehicle according to claim 1 , wherein the flat component is formed as a structural reinforcement so that the axle carrier arrangement is only load-bearing by fixing the three suspension arm brackets on the flat component and on the body.

11. The vehicle according to claim 1 , wherein the flat component is formed as an underbody of the vehicle.

12. The vehicle according to claim 11 , wherein the flat component formed as the underbody is designed as a lower aerodynamic closure of the vehicle.

13. The vehicle according to claim 1 , wherein the flat component has, on each side, a recess for a wheel of the vehicle.

14. The vehicle according to claim 1 , wherein the flat component extends at least over 10% of a perpendicular area projection of the vehicle.

15. The vehicle according to claim 1 , wherein the flat component extends at least over 20% of a perpendicular area projection of the vehicle.

16. The vehicle according to claim 1 , wherein the flat component extends at least over 30% of a perpendicular area projection of the vehicle.

17. The vehicle according to claim 1 , wherein the flat component has a maximum thickness of 150 mm.

18. The vehicle according to claim 1 , wherein the flat component has a maximum thickness of 20 mm.

19. The vehicle according to claim 1 , wherein the flat component comprises a plate element and a reinforcement structure fitted on the plate element and/or integrated in the plate element.

20. The vehicle according to claim 1 , wherein at least one of the three suspension arm brackets and/or the flat component is made from pressed composite material or fiber-composite material.
